mmlu | Question:
When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much. But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line. _ is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that's working on a factory assembly line or sitting in front of a computer. The monitor You should not have to tilt your neck up or down to lock at the screen. Your eyes should be level with the top of the screen. How far away should you sit? Reach your arm out so your fingertips just touch the screen. The keyboard It should be directly in front of you. Don't unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists "neutral," which means straight, not bent. This puts less strain on your nerves and muscles. Arms should be close to the body. Don't look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don't have to reach for it. The chair Your feet shouldn't dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there. The Body If you think of your body as a collection of right angles when you sit at a computer, you should be just fine. Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat. How high should a monitor be placed according to the passage?
Choices:
A. As high as your arms.
B. A little higher than your eyes.
C. A little lower than your eyes.
D. At the same level as your eyes. | D |
mmlu | Question:
Seligman is leading the research on what might be called Happiness Revolution in psychology. Since World War II, psychologists have focused on fixing what is broken --repairing psychosis , and neurosis . Research has piled up steadily when it comes to looking at patients who are neurotic, while the happy or joyful people among us have received little scientific examination. When Seligman did a search to find academic articles about such 'positive psychology' he found only 800 out of 70,000. 'Psychologists tend to be concerned with taking a negative 8 person, and helping him get to negative 2,' said Seligman, a psychology professor of the University of Pennsylvania. 'My aim is to _ ' In the last 50 years, statistics have shown that we are less happy as a people. 'While our quality of life has increased dramatically over that time, and we've become richer, we're in an epidemic of depression,' Seligman said. 'Depression is 10 times more common now, and life satisfaction rates are down as well.' Seligman argues that the new science he writes about is shifting psychology's model away from its narrow-minded focus on mental illness towards positive emotion, virtue and strength that increase people's happiness. If you want to be happy, forget about winning the lottery , getting a nose job, or securing a raise. In his new book, Authentic Happiness, psychologist Martin Seligman argues that overall lifetime happiness is not the result of good genes, money, or even luck. Instead, he says we can increase our own happiness by making use of the strengths and virtues that we already have, including kindness, originality, humor, optimism, and generosity. He has named the field'Positive Psychology,' arguing that we would be better off building on our own strengths rather than mourning, and, hence, trying to repair, our weaknesses. By frequently calling upon their strengths, people can build up natural barriers against misfortune and negative emotions, he said. Science has shown that there are several distinct roads to being a happy person -- though happiness might not mean what you think. Material goods -- even simple ones like ice cream, and massages -- are only stimulating things that rapidly give people a boost. To cultivate happiness, we must first find out our individual strengths and virtues. Next, apply the qualities in such a way as to enhance your happiness-generating system. The distinctive feature of Seligman's work lies in _ .
Choices:
A. evaluating the psychological state of people
B. making a study of people who suffer from mental illness
C. focusing the scientific examination on the happy or joyful people
D. figuring out the exact number of the academic articles about 'positive psychology' | C |

People who are hit by lightning and survive often have long-term effects. These may include memory loss, sleep disorders, muscle pain and depression . Experts tell people to seek the safety of a building or a hard-top vehicle any time they hear thunder, even if it is not raining. They say lightning can strike as far as sixteen kilometers from any rainfall. Lightning can travel sideways. And at least ten percent of lightning happens without any clouds overhead that you can see. People who are outdoors should make sure they are not the tallest thing around. Bend low to the ground, but do not lie down. And do not stand near a tree or any tall object. Get away from water and anything made of metal. A car is safe, but do not touch any metal inside. Safety experts say people in buildings should stay away from anything with wires or pipes that lead to the outside. The National Weather Service says if you plan to _ any electronic equipment, do so before the storm arrives. Do not use a wired telephone. Do not use water. All these can carry electricity. Some people think a person struck by lightning carries an electrical charge afterward. Experts say this is not true. It is safe to begin emergency treatment. Each year about four hundred people in the United States are struck by lightning. Last year forty four people died. The average is close to seventy. The National Weather Service says that is more than the number of people killed by severe storms. According to the passage, which of the following is NOT true?
Choices:
A. Lightning can happen even if there is no cloud.
B. Lightning won't do harm to people's health.
C. Lightning can travel sideways.
D. Lightning can strike very far. | B |
mmlu | Question:
Switzerland is one of the most developed countries in Europe. It is famous as one of the cleanest countries in the world. The Swiss think that recycling is very important. The government has made laws which require everyone to recycle. In 1998, the Swiss government passed a law which says that people can not throw away any electronic machines. Instead, people are told to bring old ones, such as televisions, computers and fridges, to special centers when they didn't need them. Many parts of the old machines are reused, and only the parts that can't be used are thrown away. The government also charges a rubbish bag tax . If people want their rubbish to be collected, they must buy yellow stickers and put them on their rubbish bags. In 2003, 47% of all rubbish in the cities was recycled. This included 70% of paper, 95%of glass, 71%of plastic bottles and 85--90%of cans. Until recently, people could get a small amount of money when they recycled their bottles. Recycling has become a daily habit for the Swiss. Everyone should learn from the Swiss, and our country will be clean like Switzerland. How can people in Switzerland get a small amount of money?
Choices:
A. Put yellow stickers on their rubbish bags.
B. Recycle their bottles.
C. Bring old electronic machines to special centers.

mmlu | Question:
Studying abroad is an amazing experience, especially when you come to Australia as an overseas( ) high school student. You can have a lot of fun here, especially on holidays. There are many festivals in Australia. The most important one is obviously Christmas. Each year, the summer holidays at every high school last about two months from the beginning of December to February, which covers the Christmas time. Since it is a long holiday, most overseas students love to fly back to their home countries to spend the time with their families and friends, but a few students still stay in Australia during the holiday to get part-time jobs. It is quite easy to find a part-time job at Christmas. Students often take part in another major social activity. They go to the beach to have fun in the sunshine. The summer in Australia is from December to February, so going to the beach in December is very popular among Australians. Easter in March is another important holiday in the year. It actually combines "Good Friday" and "Easter Monday". Almost every shop closes on Good Friday. And people usually go to see Easter Show. The Chinese New year is not a public holiday in Australia, so every Chinese student still has to go to school to study and do his or her normal duties. Summer holidays in Australia often begin in _ .
Choices:
A. July
B. September
C. December
D. February | C |

Victim recorded the call but has not brought the tape to court, although its existence is known to Defendant. Victim's testimony is
Choices:
A. inadmissible, because Victim cannot sufficiently identify the caller.
B. inadmissible, because the tape recording of the conversation is the best evidence.
C. admissible, because Defendant waived the "best evidence" rule by failing to subpoena the tape.
D. admissible, because Victim's lack of certainty goes to the weight to be given Victim's testimony, not to its admissibility. | D |
mmlu | Question:
Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health. In a new study, the researchers found that pizza is a large source of calories, saturated fat and salt in children's diets.Children should not eat more than two slices of pizza for a meal,and should pair that with salad, rather than with another high-calorie food,the researchers concluded. "Parents should aim to control pizza consumption , particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands."Said Lisa Powel, director of the Illinois Prevention Research Center. Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them.Studies have found pizza is among the greatest sources of calories for children. "Since pizza remains a common part of children's diet, we need to make 'healthy' pizza."Powel said.To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content," she said. Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. "Many foods are eaten too frequently and in large sizes," said Tindall.To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza,"she said. "Make it at home, instead of ordering it out where you don't have any control over how it's made." Tindall said. "When we make it at home, we can choose healthier ingredients,increase the vegetables, reduce fat, and put in less cheese.Pizza doesn't have to be just pepperoni and cheese." What is the best title for the passage?
Choices:
A. Pizza--a real junk food!
B. How to prepare better meals for your kids?
C. Discover the harm of eating pizza
D. Bring in healthier pizza for Americans | D |
mmlu | Question:
A woman renewing her driver's license at the County Clerk's office was asked to state her occupation.She hesitated, uncertain how to classify herself. "What I mean is," explained the recorder, "do you have a job, or are you just a ..." "Of course I have a job," said Emily."I'm a mother." "We don't list 'mother' as an occupation... 'housewife' covers it," said the recorder. One day I found myself in the same situation.The clerk was obviously a career woman, confident and possessed of a high sounding title."What is your occupation?" she asked. The words simply popped out."I'm a Research Associate in the field of Child Development and Human Relations." The clerk paused, ballpoint pen frozen in midair. I repeated the title slowly, and then I stared with wonder as my statement was written in bold, black ink on the official questionnaire. "Might I ask, " said the clerk with new interest, "Just what you do in this field?" Coolly, without any trace of panic in my voice, I heard myself reply, "I have a continuing program of research (what mother doesn't), in the lab and in the field (normally I would have said indoors and out).Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it).But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money." There was an increasing note of respect in the clerk's voice as she completed the form, stood up, and showed me out. As I drove into our driveway, buoyed up by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3. Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern. I felt proud! I had gone on the official records as someone more distinguished and indispensable to mankind than "just another mother." Motherhood...What a glorious career! Especially when there's a title on the door. What is the author's purpose of writing the passage?
Choices:
A. To show how you describe your job affects your feelings toward it.
B. To argue that motherhood is a worthy career and deserves respect.
C. To show that the author had a grander job than Emily.
D. To show that being a mother is hard and boring work. | B |

That day It's 4 am,and Danilo C.Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum,Sarangani,in the far south of the Philippines. A few minutes later,he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully,figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs,roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fine-mesh fence. It is here that he buries the turtle eggs he has collected. Today,Dequina scoops out a hole,puts the eggs in it,and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carty the hatchlings to the shore,and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free most are hunted down by natural predators,and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction,including four that come to the shores of Sarangani to lay their eggs --the Hawksbill,Olive Ridley,Loggerhead and Green Turtles. After learning about their _ , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles,"52-year-old Dequina says. "If they see turtle eggs,they will either bring them to me or inform me of the nesting places." Over the past seven years,more than 3,000 hatch- lings have been released to the ocean. Dequina walks along the shore to _ .

mmlu | Question:
Indonesia's coral reefs are in trouble. Coral mining, Industrial pollution and poisonous agricultural runoff all play a role in their destruction, but the fishermen have been the worst offenders. They not only bomb fish but also poison them with cyanide, an equally destructive practice. The fishermen are also among the biggest potential victims . Two thirds of Indonesia's 7, 000 coastal villages are close to coral reefs and thus depend for their livelihood on the harvest of reef fish. The disappearing reefs are already leading to a dramatic decline in the productivity of coastal fisheries and to increasing fights among fishermen. Indonesia's reefs are vast - they cover 51, 000 square kilometers, surround 17, 500 islands and stretch 3,500 kilometers - but they are not infinite. Many foreign experts and Indonesians fear that the region's entire marine environment could be seriously damaged if the reefs keep dying at their present rate. "The overall picture is depressing," says Ian Dutton, Indonesian director of an environmental group. Depressing, but not hopeless. Despite the destruction, environmentalists have in recent years made significant progress in changing the hearts and minds of the fishermen. Working closely with local Indonesian authorities in North Sulawesi and less populated eastern Indonesia, where most of the country's reefs are located, they have succeeded in preventing destructive fishing practices and coral mining from overwhelming the reefs. Increasing numbers of fishermen are waking up to the threat and protecting the life-sustaining coral before it's too late. Nuhung, a 56-year-old fisherman, says, "I always knew blast fishing was harmful. Then I suddenly realized that by bombing the reefs I was destroying not only my own but my children's future." The fishermen are named "worst offenders" because_.
Choices:
A. they defend their rights of mining the coral reefs too eagerly
B. they wake up too late to realize the terrible situation
C. they use the fishing ways, which destroy the coral reefs
D. they pretend to follow the government's rules | C |

mmlu | Question:
A group of people from Denmark have formed the B-Society. According to them, human beings are divided into types: A-People, and B-People. A-People have no problem getting up in the morning, and operate much better earlier in the day. However, B-people are better later in the day. "I'm useless early in the morning," says one of the members of the B-Society."All I can do is drink coffee, and stare into space. People used to get up early because they had to feed the animals. But I haven't got any cows or chickens, so I can sleep late," She adds. Since the society was set up, the B-Society has welcomed several thousand members. Right now, the B-Society is fighting hard for businesses to join its B-certification list. Companies that are "B-certified" basically give their employees the opportunity to come in when they want. In some companies, employees arrive at any time up to 3:30 pm --- each to their own rhythm . And it is not just businesses that are benefiting from this. Teenagers who can't get out of bed in the morning, and parents who never quite get the kids to school on time, can now benefit from B-classes. From next year, a school in Copenhagen will offer classes which start later in the day (at 10 instead of eight). And even the government seems to like the idea. The B-Society was founded by Camilla Kring, a professor from the University of Copenhagen. On her website, she says, "When B-people's work rhythms are considered at the work place, their productivity and quality of life is increased, which can increase productivity for the entire organization." She adds that, "B-Society will create a new daily rhythm in schools and other institutions as an alternative to the current rhythm of 'early at work and early at home'. We are working for the establishment of kindergartens, primary and secondary schools as well as universities that open between 10 am and 8 pm." Would you like to work for a B-certified company? The author's purpose in writing this text is to _ .

Internet users can give websites a thumbs up or thumbs down in less than the blink of an eye, according to a recent study by Canadian researchers. Specifically, a positive or negative decision is made within one-twentieth of a second -- less than half the time it takes to blink.It is also about the time for users to read just one word on the website. In the study at the Carleton University in Ottawa, websites were flashed up on a screen for participants to view for 50 milliseconds, and then rated by the viewer. Later when the pages were viewed again for longer periods of time, the viewers' opinion were the same. The study was published in the March/April issue of the journal Behaviour & Information Technology. "It really is just a physiological response.If the first impression is negative, you'll probably drive people off," said Dr.Gitte Lindgard, the leading researcher, "So Web designers have to make sure they're not offending users visually." However, the results did not show how to win a positive reaction from users."When we looked at the websites that we tested, there is really nothing there that tells us what leads to dislike or to like," Dr.Lindgard said. Usually the appeal of a website is tied to color1, movement and interactivity .And while further research may offer more clues , personal taste would always be a limiting factor, according to Lindgard. "If the designs were _ to a set of principles, wouldn't we find an awful lot of similar houses, gardens, cars?" she said."We'd have no variety." How long does it take have a blink of the eye?

A baby giraffe is born 10 feet high and usually lands on its back. Bringing a giraffe into the world is _ . In his book, A View from the Zoo, Gary Richmond describes how a new-born giraffe learns its first lesson. The mother giraffe lowers her head long enough to take a quick look. Then she puts herself directly over her child. She waits for about a minute, and then she does the most unreasonable thing. She throws her long leg and kicks her baby, so that it's sent sprawling . When it doesn't get up, what the mother has done is repeated again and again. The struggle to rise is important. As the baby giraffe grows tired, the mother kicks it again. Finally, it stands for the first time. Then the mother giraffe kicks it off again. Why? She wants it to remember how it can get up. In the wild, a baby giraffe must be able to get up as quickly as possible to stay with its group, where there's safety. Another writer named Irving Stone understood this. He spent a lifetime studying great people, writing stories about such men as Michelangelo, Vincent van Gogh, Sigmund Freud, and Charles Darwin. Stone was once asked if he had found something unusual about these great people. He said, "I write about people who sometime in their life have a dream of something. They're beaten over the head, knocked down and for years they get nowhere. But every time they stand up again. And at the end of their lives they've realized some small parts of what they set out to do." The mother giraffe puts herself over her child and throws her long leg and kicks her baby because she _ .

Anne and Joseph are talking about an interesting question. Why do some people change their names? There can be many reasons. Hanna changed her name to Anne because she thought it would be easier for people to remember. On the other hand, Joseph is thinking about changing his name to an unusual name because he wants to be different. People have a lot of reasons for changing their names. Film stars, singers, sportsmen and some other famous people often change their names because they want names that are not ordinary, or that have special sound. They chose the "new name" for themselves instead of the name their parents gave them when they were born. Some people have another reason for changing their names. They have moved to a new country and want to use a name that is usual there. For example, Li Kaiming changed his name to Ken Lee when he moved to the United States. He uses the name Ken at his job and at school. But with his family and Chinese friends, he uses Li Kaiming. For some people, using different names makes life easier in their new country. In many countries, a woman changes her family name to her husband's after she gets married. But today, many women are keeping their own family name and not using their husband's. Sometimes, women use their own name in some situations and their husband's in other situations. And some use both their own name and their husband's. Famous people want their new names to _ .

Read the following interview with Dr John Bass, an international shark specialist who has spent many years studying sharks: First of all, doctor, are all sharks dangerous? No, they aren't. There are about 250 different kinds of sharks, but fewer than 30 of them are dangerous to humans. Certain sharks are very aggressive and we should fear them, but the danger of shark attacks is much lower than most people think. So which sharks are dangerous? The Great White shark is the most dangerous. Then there is the Tiger shark, which other sharks are afraid of, and the Blue shark. Both of them are very fast and dangerous. Which are the biggest and smallest sharks? The Whale shark is the biggest shark in the world. It grows up to 15 m in length and weighs as much as six large cars. The smallest shark, which is found near prefix = st1 /Japan, could fit into the palm of your hand because it is only 15-20 cm long. Do all sharks have teeth ? Yes, they do. Most sharks have hundreds, sometimes even thousands, of sharp teeth. These are arranged in rows of four or more. They fit quite loosely in the jaw. When the front ones break off or fall out, spare teeth move forwards from the rows behind: Sharks get a new set of teeth every two weeks. In 10 years, a Tiger may lose as many as 24,000 teeth! That's lots of teeth! What kind of food do sharks eat? Most sharks feed on small fish, and they keep the oceans healthy by eating sick and injured fish. However, hungry sharks will eat almost anything, including smaller sharks and even rubbish. Inside one Tiger shark which was found, there was a tin can, a bicycle tyre , a leather wallet and an alarm clock! And how do sharks find their food, doctor? A shark's sense of smell is excellent. It will follow the smell of blood across thousands of metres of ocean. They also see well, and they have good hearing. Sharks can feel movement in water very easily too, and it is possible for them to feel a fish moving as far as 30 m away. Choose the best title for this passage _ .

Sheep always follow each other and never really think about where they are going. Perhaps fashion makes us into " _ ". Maybe we should find our own way and not follow the crowd. Everyone wants to wear top brand clothing. However, we should remember that clothes designers study what ordinary people wear on the street. Then they make clothes like ordinary people's for everyone. Therefore, fashion really starts with individual finding a new look. Then a company uses that look and then it becomes fashionable! That doesn't mean you will. That is to say, a model might look perfect in a shirt but that doesn't mean you will. The same goes for mobile phones. Young people are always asking me when to change my mobile phones. Mobile phone companies are always putting new functions on their phones but do we really need all these extra functions? I use my phone to call people and to send messages to my friends. I don't need a camera, Internet surfing or a calendar on my phone. Again, if you buy the latest phone, it will only be the latest phone for a month or so. Then something new will come out and you'll be unfashionable again. You can't keep up with fashion all the time, so you don't need to follow the fashion. The passage is written mainly to _ .

It was late in a spring afternoon. I was sitting at a fruit stand beside Beihai Lake looking at the shinning ripple , which awoke me to a full sense of life. A mother and her daughter were sitting opposite to me. The latter, a lovely girl of seven or eight with a pretty, small nose, was occupied with an ice cream. Her mother, holding the child's sweater, was whispering to her. A sudden breeze blew and the child sneezed. Her mother rapidly put the sweater on her and began to button it up. In her hurry the buttons were wrongly matched, which was unnoticed by her until several had been done. The mother at once unbuttoned the sweater and did it again. Such an unimportant incident, however, did not escape the child's eye. "Ha-ha, mum, see how your mind has wandered!" said the girl with a loud laughter, which brought a bit angry look to the mother's face. As an onlooker, I imagined a good dressing down for the little girl because of the impolite remark she made. But instead there was only an embarrassing interval of a few seconds. Then I heard the mother's gentle voice: "Yes, it surely has, for my heart has gone out to you!" said the mother, pointing a kind finger at the girl's little chest. The child blinked puzzlingly, hiding her red face in the arms of her mother who hugged her gently. A smile of satisfaction spread over the mother's face. I was deeply moved by the scene of motherly love. What was the most praiseworthy thing about the mother was her way of treating the child's behavior. Nowadays many people seem to forget that the best way to educate a child is not tolerating or blaming, or even moral lecturing, but tender enlightening with love. How did the mother treat her daughter's loud laughter?
Choices:
A. She tolerated it.
B. She enlightened her daughter with love.
C. She gave her daughter a lesson.
D. She ignored it. | B |
mmlu | Question:
Loren Gladstone of Toronto is 58, but thinking over how to bequeath his digital property . Doing the paperwork after his parents' death was a challenge. "When my time comes, I wonder if my children will even know what paper is," he says. As a software developer, his virtual property is both valuable and vital to his business. That reflects a problem. Online lives have increasing economic and emotional value. But testamentary laws offer confusing and incomplete ways of bequeathing and inheriting them. Digital property may include software, websites, downloaded content, online gaming identities, social-media accounts and even e-mails. In Britain alone holdings of digital music may be worth over PS9 billion ($14 billion). A fifth of respondents to a Chinese local-newspaper survey said they had over 5,000 yuan($790) of digital property. And value does not lie only in money."Anyone with kids under 14 years old probably has two prints of them and the rest are in online galleries,"says Nathan Lustig of Entrustet, a company that helps people manage digital property. Service providers have different rules--and few state them clearly in their terms and conditions. Many give users a personal right to use an account, but nobody else, even after death. Facebook allows relatives to close an account or turn it into a memorial page. Gmail (run by Google) will provide copies of e-mails to an executor . Music downloaded via iTunes is held under a license which can be abolished on death. Apple declined to comment on the record on this or other policies. All e-mail and data on its iCloud service are deleted on the death of the owner. This has led to cases to court in America. In 2004 the family of Justin Ellsworth, an army man killed in Iraq, took Yahoo! to court in Michigan to get copies of his e-mails. This year, a court in Oregon ruled that another American mother whose son had died could use her dead son's password to enter his Facebook account for a short period. Now five American states have made laws giving executors control over the social-networking accounts of dead users. But this raises the subject of privacy. Passing music on is one thing; not everyone may want their relatives to read their e-mails. Colin Pearson, a London-based lawyer, says access should come only with a clear provision in a will. But laws, wills and password safes may be contrary to the providers' terms of service, especially when the executor is in one country and the data in another. Headaches for the living and lots of lovely work for lawyers. Which of the following can be inferred from the passage?
Choices:
A. Digital property is assessed in terms of nothing except money.
B. No laws in America have been made to deal with digital property.
C. The relatives may read the e-mail of the dead without permission.
D. Lawyers can make money through cases about digital property. | D |

Lu Jialei, 14, from Hangzhou Foreign Language School, won the CCTV Chinese Character Spelling Contest on Oct 18th, 2013. About 160 people competed. The host read a word to the contestant, explained its meaning and gave sample sentences. The contestant was required to write down the word. Winning the contest was a "surprise" to Lu. "I was not the smartest one," she said. "But I paid attention to details." To prepare for the contest, she and her teammates studied the Modern Chinese Dictionary for 10 days. There are more than 56,000 entries including characters, words and phrases in it. She also had a secret weapon. She studied how Chinese characters were formed. "When others paid attention to the plot of a story, she looked at how authors use words and sentences to express themselves," said Su Yunsheng, Lu's Chinese teacher. Su is happy to see students like Lu find the beauty of Chinese language.

In Friendship 7, Glenn radioed, "The lights show up very well. Thank everybody for turning them on." His capsule moved on to the east. "During his three orbits of the earth, Glenn could always reach one of the 18 tracking stations. Some of them were on ships at sea. Others were in theUnited States. Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands asNigeria, Zanzibar andMexico, there would have been breaks in the worldwide radio network. John Glenn, Jr. was the first American to orbit the earth. For his flight, the tracking network covered 60,000 statute miles . 500 men worked in the stations along the route. Since his flight, the network has grown.

mmlu | Question:
About influenza A(H7N9) virus What is the influenza A(H7N9) virus? Influenza A H7 viruses are a group of influenza viruses that normally spread among birds. The influenza A(H7N9) virus is one smaller group among the larger group of H7 viruses. Although some H7 viruses (H7N2, H7N3 and H7N7) have sometimes been found to infect humans, no human infections with H7N9 viruses have been reported until recent reports from China. What are the main signs of human infection with influenza A(H7N9) virus? So far, most patients with this infection have had severe pneumonia . Signs include fever, cough and shortness of breath. However, information is still limited about the full area of disease that infection with influenza A(H7N9) virus might cause. How did people become infected with the influenza A(H7N9) virus? Some of the confirmed cases had connections with animals or with an animal environment. The virus has been found in a pigeon in a market in Shanghai. It is not yet known how persons became infected. The possibility of animal-to-human spread is being looked into. Is it safe to eat meat like chicken and pork products? Influenza viruses are not spread through eating well-cooked food. Because influenza viruses are made inactive by normal temperatures used for cooking (so that food reaches 70degC in all parts), it is safe to eat properly prepared and cooked meat. Diseased animals and animals that have died of diseases should not be eaten. In areas experiencing outbreaks, meat products can be safely eaten only if they are properly cooked and properly handled during food preparation. The eating of raw meat and uncooked blood-based dishes is a high-risk practice and should be discouraged. Is it safe to travel to China? The number of confirmed cases in China is very low. WHO does not advise the application of any travel measures with respect to visitors to China, nor to persons leaving China. Are Chinese products safe? There is no evidence to link the present cases with any Chinese products. WHO advises that people should not fear to trade them at this time. It is not safe to eat _ .

Reached My Destination "Ego has an enormous appetite, the more you feed it, the hungrier it gets." --Nathaniel Bronner Jr. It has been two years, we have not met. Last time was when we were departing at Rome Airport as a procedure of joining different competitive firms. We exchanged our personal email IDs and I never realized my email ID was one with an error. We had been in six years of professional relationship that ended with a small misunderstanding. We never realized that we might not get a chance to clear it. We both had tough ego levels to shed off. In these two years work has always kept me busy. There have been instances where I wanted to write to him for his expertise advice but my ego always stopped me. And then one day flying to London for a conference was taking away my peace of mind. I knew he would be there as a part of the event from his firm. I thought to ignore him and behave professionally as an employee. Finally, I entered the conference hall. I was quick enough to realize that he would take over participants' attention with his confidence, and all I would do sitting there would be appreciating him, nodding my head as "Yes to Yes" and "No to No". Finally, he approached the stage. The very first line that fell into my ears was my name as he continued, "I am proud to be here with 8 years of experience and I would like to share my best practices with all of you. This is a journey I completed with one of my best colleagues and my best friend 'my name' who supported me through day and night with the toughest projects and killing deadlines". For a moment I fell numbed and completely lost. All I could remember were my thoughts for him before entering the room and his greatness to acknowledge my presence. Finally, the conference ended and we all left for refreshment. I was struggling hard to face him. I saw him coming towards me with a gift. I asked him, "Why this gift?" He was very humble to answer, 'This is a small symbol of friendship to tell how much I missed my friend when I wanted her the most. A small token to represent that even when you were not with me, your teachings helped me to work on difficult projects." I asked curiously, "But you never wrote to me, if I was so important and helpful." He replied, "You left me with an email ID that is not reachable, maybe you missed a letter. I had no number to call you either but when I read your name in the list, I did all these arrangements. We never know when we meet again in life, so this gift is for you my friend." Finally, we again departed to our respective destinations but this time with a smile. The writer didn't email her friend because _ .

Ashenden knew several European languages and the fact that he was a writer provided excellent cover: on the pretext that he was writing a book he could, without attracting attention, visit any neutral country. It was while they were discussing this point that the Colonel said, "You know you might get material that would be very useful to you in your work. I'll tell you an incident that occurred only recently. Very dramatic. A foreign government minister went down to a Mediterranean resort to recover from a cold and he had some very important documents with him that he kept in a dispatch case . A day or two after he arrived, he picked up a beautiful blonde at some restaurant or other, and he got very friendly with her. He took her back to his hotel, and when he came to himself in the morning, the lady and the dispatch-case had disappeared. They had one or two drinks up in his room and his theory is that when his back was turned the woman slipped a drug in his glass. "Do you mean to say that happened the other day?" said Ashenden. "The week before last." "Impossible," cried Ashenden. "Why! We've been putting that incident on the stage for sixty years, we've written it in a thousand novels. Do you mean to say that life has only just caught up with us?" "Well, I can guarantee the truth of the story." said the Colonel, "And believe me, the government has been put to no end of trouble by the loss of the documents."

The following are four books that will help you change your mind and change your life. 1) You Can Heal Your Life, Louise Hay:A groundbreaking book when it was released in 1982.It is still the book that I turn to when I have physical unrest that requires deeper understanding.Louise Hay is the pioneer in looking at the connection between the physical unrest that we have in our body and the emotional connection.At the time that she wrote the book many people scoffed at this idea,but it is now widely accepted and millions of people refer to it on a daily basis. 2) The Four Agreements,Don Miguel Ruiz:Maintaining a sense of reliability and faith is developed through understanding according to The Four Agreements by Don Miguel Ruiz written in 1997.We are faced with rules and regulations:don't do this,don't do that,watch what you are doing,be kind,loyal,faithful, etc.The four agreements represent a simple system of maintaining your own inner authority while practicing being a true person with other people. 3) Slowing Down to the Speed of Life,Richard Carlson and Joseph Bailey:This is a new one in my "bedside collection" and one that has made the biggest impact on me 1ately.Written in 1997, it is even more relevant today than it was when it was written.The idea of "slowing down'' to get there faster was extremely hard for me to understand.As a human species we seem to enjoy moving fast and expecting quick results,especially from ourselves,I should be successful now in contrast to ''in the fullness of time" when I am ready. 4) The Game of Life and How to Play it,Florence Scovel-Shinn:A classic book that was first published in 1925 and remains one of my favorite books of all time.Scovel-Shinn understood the power of our words to express either our deepest desires or our most horrible nightmares. So where does this leave you? The way I see it is if you want to "Heal Your Life" then you had better learn how to play "The Game of Life" by learning how to "Slow Down to the Speed of Life" and keep the "Four Agreements",the Solutions may not be easy to do but it is simple.In fact, most solutions are pretty simple,and it is us humans that want to complicate it.

Isabella Stewart was born in New York City in 1840. Her father made a great deal of money in trade. During school,her parents took her to Italy to explore the country's many cultural treasures. One of the private art collections Isabella visited in Milan had a deep influence on her. She wrote to her friends about her dream of owning a house one day with an art collection like the one she had seen in Italy. In Paris, Isabella became a close friend of one of her classmates, Julia Gardner, whose family was from Boston. Julia would later introduce Isabella to her brother, Jack. In 1860, Isabella Stewart married Jack Gardner. The couple had too much art to fit inside their home. So they decided to start planning a museum. Mrs. Gardner didn't like the cold and empty spaces of many museums during her time. She wanted a warm museum filled with light. She once said that she decided years ago that _ . America was a young country developing quickly in other areas. But the country needed more chances for people to see beautiful examples of art. After her husband's death in 1898, Isabella knew she had no time to lose in building her museum. She bought land, hired a building designer, and supervised every detail of her museum's construction. Mrs. Gardner opened her museum on January 1,1903. The museum was then called Fenway Court. She invited her friends that night for a special musical performance. The next month, she opened the museum to the public. At first, visits were limited to twenty days out of the year. Visitors paid one dollar to enter. Isabella Stewart Gardner died in 1924 in Boston.

A super drug that could remove Alzheimer's ,heart disease and diabetes and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the " longevity genes" will allow millions to live longer, predicts Dr Nir Barzilai. Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer's. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise. Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. " The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing," he said. Of the three longevity genes, two genes increase the production of so-called good cholesterol , which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai's team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: " 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100." But Andrew Ketteringham of the Alzheimer's Society said: "Alzheimer's disease, a most common disease, is likely to be caused by a combination of genetic disosition , lifestyles and life events. Many genes are probably involved. What is Andrew Ketteringham's attitude toward the study?

Preface to the fourth edition A practical English Grammar is intended for intermediate and post-intermediate students. We hope that more advanced learners and teachers will also find it useful. The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on conversational forms. 1. Explanation and examples have been brought up to date. 2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of places, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns. In the fourth edition the main changes are as follows. 3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice. 4. The contents list now summaries every edition heading, and there is a new index containing many more entries references. In this edition the sign "~" is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign "="sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech. We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

"Mum,what does it mean when someone tells you that they have a skeleton in the closet ?"Jessica asked. "A skeleton in the closet?"her mother paused thoughtfully. "Well, it' s something that you would rather not have anyone else know about. For example,if in the past,someone in Dad' s family had been arrested for stealing a horse,it would be 'a skeleton in his family' s closet'.He really wouldn' t want any neighbor to know about it." "Why pick on my family?" Jessica' s father said with anger. "Your family history isn' t so good,you know. Wasn' t your great-great-grandfather a prisoner who was transported to Australia for his crimes?" "Yes,but people these days say that you are not a real Australian unless your ancestors arrived as prisoners." "Gosh,sorry I asked. I think I understand now," Jessica cut in before things grew worse. After dinner,the house was very quiet. Jessica' s parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband,who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica' s closet. Just as she opened the door and reached in to hang a skirt,a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor.

Even bird brains can get to know an entire continent ----- but it takes them a year of migration to do so, suggests a Princeton research team. The scientists have shown that migration adult sparrows can find their way to their winter nesting grounds even after being thrown off course by thousands of miles. The team first brought 30 sparrows to Princeton from northern Washington State, where the birds had been in the process of migrating southward from their summer breeding grounds inprefix = st1 /Alaska. Half the birds were juveniles of about three months in age that had never migrated before, while the other half were adults that had made the round trip to their wintering site in the south-western United States at least once. After the birds were released, they attempted to resume their migration, but both age group grew disoriented quickly. "All the birds scattered at first," Wikelski said. "It was clear that they were turned around for a couple of days. But while the adults eventually realized they had to head southwest, the younger birds resumed flying straight southward as though they were still in Washington." "The adults," said team member Richard Holland, "recovered their bearings because they possess something the younger birds do not, which is an internal map." "These birds need two things to know where they are and migrate effectively: a 'map' and a 'compass'," saidHolland, a postdoctoral research associate in Wikelski's lab. "What we've found is that juveniles use their compass, but the adults also use their map." Hollandsaid, "The birds do not lose the compass as they age, but somehow develop the map, eventually applying both tools to keep on track during migratory flights. Scientists already have determined that the compass is based on the sun or the magnetic field, but where the map comes from remains a mystery----one that the team will be exploring in coming years." Scientists are still not sure _ .

mmlu | Question:
One evening after dinner, Mr. and Mrs. Tisich called a family meeting. --We've had to make a difficult decision, Mr. Tisich announced. --You see, your mother has been offered a post as co-director of a television station in Chicago. Unfortunately, the station is not here. After thinking long and hard about it, we've concluded that the right decision is to move to Chicago. Marc looked shocked, while his sister Rachel breathlessly started asking when they'd be moving. --It's surprising, but exciting! she said. Marc simply said, --We can't go--I can't leave all my friends. I'd rather stay here and live with Tommy Lyons! The Tisichs hoped that by the time they moved in August, Marc would grow more used to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings. When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyon's house, but Mrs. Lyons said she hadn't seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly. What they didn't know was that Marc had started walking over to Tommy's house, with a faint idea of hiding in Lyons's attic for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood: the fence that he and his mother painted, the tree that he and his sister used to climb, and the park where he and his father often took evening walks together. How much would these mean without his family? Who make them special in the first place? Marc didn't take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons the right size to hold his record collection. The reason for Marc's going home was that _ .

The sun is shining when I get on No. 151 bus. We passengers sit jammed together in heavy clothes. No one speaks. That's one of the unwritten rules of Chicago _ . Although we see the same faces every day, we prefer to hide behind our newspapers. The phenomenon is striking: people who sit so close together are using those thin sheets of newsprint to keep their distance. As the bus approaches the Magnificent Mile, a voice suddenly rings out: "Attention! Attention!" Papers rattle . Necks crane . "This is your driver speaking." We look at the back of the driver's head. His voice has authority. "All of you put your papers down." The papers come down, an inch at a time. The driver waits. The papers are folded and placed on our laps. "Now, turn and face the person next to you. Go ahead." Amazingly, we all do it. Still, no one smiles. I face an older woman, her head wrapped tightly in a red scarf. I see her nearly every day. Our eyes meet. We wait, unblinking, for the next order from the driver. "Now, repeat after me..." It is a command, delivered in the tones of a drill sergeant . "Good morning, neighbor!" Our voices are weak and timid. For many of us, these are the first words we have spoken today. But we say them at the same time, like schoolchildren, to the strangers beside us. We smile and can't help it. We have said it; the barrier has been broken. Good morning, neighbor. It is not so hard after all. Some of us repeat it. Others shake hands. Many laugh. The bus driver says nothing more. He doesn't need to. Not a single newspaper goes back up. I hear laughter, a warm sound I have never heard before on bus No. 151.

Victim, injured by Driver in an auto accident, employed attorney First to represent him in the matter. Victim was chronically insolvent and expressed doubt whether he could promptly get necessary medical treatment. Accordingly, First wrote into their contract his promise to Victim "to pay from any settlement with Driver compensation to any physician who provides professional services for Victim's injuries." The contract also provided that First's duties were "nonassignable." First immediately filed suit against Driver. Victim then sought and received medical treatment, reasonably valued at $1,000, from Doctor, After receiving a bill from Doctor for $1,000, Victim immediately wrote Doctor explaining that he was unable to pay and enclosing a copy of his contract with First. Victim then asked First about payment of this bill, but First requested a release from their employment contract, stating that he would like to refer Victim's claim to attorney Second and that Second was willing to represent Victim in the pending lawsuit. Victim wrote a letter to First releasing him from their contract and agreeing to Second's representation. A copy of this letter was sent to Doctor. Second subsequently promised First to represent Victim and soon negotiated a settlement of Victim's claim against Driver which netted $1,000, all of which was paid by Victim to creditors other than Doctor.

mmlu | Question:
Nowadays, there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air, while good for our lungs, could make global warming worse. And the pollutants still go up around the air, along with carbon dioxide. These pollutants are called aerosols and they include soot as well as mixtures of nitrogen and sulfur and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air. "There are so many different kinds of aerosols," she says. "Some warm and some cool. But in fact, humans are giving out a lot of extra aerosols, and they tend to cool for the most part." The aerosols reflect sunlight back into space, or keep us cool. But it turns out that's not all they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea. "They can add nutrients, for example, to the oceans or to the land," Mahowald says. "But also while they're in the atmosphere they can change the climate, and thus that also can influence the amount of carbon, the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other." Mahowald's results suggest that reducing those pollutants could be an even bigger problem than realized, when you consider that aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment, but this could turn out to be quite significant. And studying it is not easy because the effects aren't well understood. For example, nitrogen can be a fertilizer , but it can stop plant growing when nitrogen comes out of the air in acid form. Right now it seems like we're much more likely to clean up aerosol pollution, while increasing the amount of carbon dioxide in the air. So scientists, unfortunately, may have a chance to see whether this experiment on our planet should continue or not. What does the last sentence of the passage imply?
Choices:
A. Scientists will be in a dilemma.
B. The experiment will be successful.
C. Scientists will carry out the experiment.
D. Scientists have difficulty in the experiment. | A |

mmlu | Question:
Three years ago I listened to a lecture on cognition that changed the way I think about intelligence. There are two types of cognition, and the first is normal cognition the ability to regain knowledge from memory. The second type of cognition is metacognition the ability to know whether or not you know. Does this affect intelligence? In traditional education, intelligence is measured by cognitive ability. Some people can easily produce everything they know on a test. But others are awarded with poor grades and considered inferior (not as good as). But does this inability make them any less intelligent? If the question came up on a task, they could refer to a book or a quick Google search. In reality they're just as effective as the people that ace a test. They just can't prove it as easily. Metacognition is more important to success than cognition. A person with poor cognitive ability, but great metacognitive ability might do poorly in school, but when faced with a challenge, they understand their abilities and _ . For example, when faced with a question, a person with strong metacognitive ability will deal with it like this. If he knows the answer, but can't come up with it, he can always do a bit of research. If he knows for sure that he doesn't know, then he can start educating himself. Because he's aware of his ignorance, he doesn't act with foolish confidence. These people might not seem intelligent at first glance, but because they know what they know, they make better decisions and learn the most important things. However, people with great cognitive ability but poor metacognitive ability may be considered excellent at a young age for acing every test and getting great SAT scores. Unfortunately, they've been ruined by poor metacognition they think they know everything but they really don't. They are arrogant (overconfident), fail to learn from mistakes, and don't understand the slight differences of personal relationships, showing disregard for persons with lower cognitive ability. They may make the worst decisions. The most important mental power is the ability to know what you don't know .The recognition of a fault is the first step to improvement. Don't try to hide a lack of knowledge. For intelligent people this is the toughest lesson to learn. People with great cognitive ability tend to _ .

In New York City public schools, 176 different languages are spoken among the more than 1 million students. For 160,000 children, English is not their first language. New York's Department of Education makes learning better for these students by providing dual-language programs, in which students are taught in two languages, English and another one, like Russian or Chinese. Math, social studies, science and all other regular courses are taught in both languages. And they learn about the culture of the other country. Milady Baez, Deputy Chancellor of English Language Learners and Student Support, says these dual-language programs will help children succeed in the future. "The jobs of the future require that our students know more than one language. They are going to be traveling abroad; they are going to be communicating with people from all over the world. This will open doors for them." Middle-schoolers might not have jobs on their minds yet. For Kequing Jaing, she likes keeping up her first language, Mandarin."It makes me feel that I am home because I can speak in Chinese, learn in Chinese, while learning in English. So it makes me feel better and makes me understand more about the task I'm learning."[:ZSSxxSSk.Com] Anastasia Hudikova came to the United States when she was 2 years old. She says the Russian-English program keeps her connected to her heritage and her parents happy."They're really happy about the program. They are really happy that I can preserve my culture and my language, and that I can speak it fluently in school." The New York schools also offer dual-language programs in seven other languages: Arabic, French, Haitian Creole, Hebrew, Korean, Polish and Spanish. There are plans to add even more languages in the future. While these dual-language programs are popular, some organizations in the U.S. say teaching English comes first. U.S. Studies show that children who learn English early will be more successful later. Who may not quite agree with dual-language programs?

If you'renotmakingmistakes,you'renottryinghardenough. It's good to make mistakes. That's not a _ , folks,and I have not lost my mind. It is good to make mistakes, and here's why. First of all, mistakes are a clear sign that you are trying new things. It's always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you expand? How can you innovate? The simple answer is, "You can't." Look around you. With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new. Another good thing about mistakes is this: when you are making mistakes, you are learning. Consider this: Edison failed 10,000 times before he perfected the light bulb. When asked how he felt to fail that many times, he remarked that he hadn't failed 10,000 times, but rather had learned 10,000 things that didn't work. Finally, when you make a mistake you are that much closer to success. Why? Because when all is said and done, you will have tried some finite number of things before you succeeded. Every time you made a mistake you eliminated one of those things and are one step closer. But this all doesn't mean that you should forge ahead with disregard for the consequences of a mistake. Quite the contrary, when you try something new you have to be willing to set some reasonable limits so that, in the event that it doesn't work out the way you want it to, you will be in a position to try again. We all have limited resources in the form of time and money, so don't blow them all on one approach to a problem. Realize that it probably won't be perfect the first time and allocate these resources appropriately so you can learn, modify, and try it again. Only by embracing and using your mistakes in this way can you make significant advances in your business and your career. There is an old axiom that goes, "If you're not making mistakes, you're not trying hard enough." So go forth and make mistakes. And learn. And grow. And prosper. It's good to make mistakes as long as _ .

A. people use them positively

The king was to pass by a beggar's small poor house and the man was excited, not because he was about to see the king but because the king was known to part with expensive jewels and huge sums of money when moved by sympathy. He saw the king's carriage just when a kind man was filling his begging bowl with uncooked rice. Pushing the man aside, he ran into the street, shouting praises of the king and the royal family. The carriage stopped and the king beckoned to the beggar. "Who are you?" he asked. "One of the most unfortunate of your people," said the beggar. "Poverty sits on my doorstep and follows me about like a dog. I haven't eaten since yesterday afternoon!" "Have you nothing for your king except great sorrow?" said the ruler, putting out his hand. "Give me something." The beggar, astonished, carefully picked up 5 grains of rice from his bowl and laid them on the king's outstretched palm. The king drove away. The beggar's disappointment was great. He complained and cursed the king again and again for his miserliness. When he returned home in the evening he found a bag of rice on the floor. "Some generous soul has been here," he thought and took out a handful of rice from the bag. To his astonishment, there was a small piece of gold in it. He realized then that the bag had been sent by the king. He emptied the rice on the floor, feeling sure there would be more gold pieces in it, and he was right. He found 5, one for each grain of rice he had given the king. "It is not the king who has been miserly," thought the man, sadly.

Hannah Levine decided she wanted to give hugs to all of the children and families in need at local hospitals. Because she couldn't give them one by one, Levine, then a sixth-grader, decided she would use her talents to do the next best thing. She began to knit hats, scarves, and blankets for families staying at the Ronald McDonald House at Stanford. Her creations also went to Bundle of Joy, a program that provides newborn baby items for families in need, and to Knitting Pals by the Bay, a local organization that provides hand-knitted caps to cancer patients. "I love to knit, and I thought it would be a great idea to make all these handmade items for kids and adults who need them. It would be like a hug for them," Levine explained. Levine started the project about a year ago. "I think it's just really fun to do, and it keeps me busy," said Levine, now 13. Once she got started, Levine realized that her project could be much bigger than the goods she was able to produce with just her own hands. So she sent emails to her school and communities , asking for knitted donations to the project she named "Hannah's Warm Hugs". She also posted advertisements at Starbucks and other locations in her area. The warm goods began to _ . "It was amazing; more strangers than people she knew started dropping donations at our door," said Levine's mother, Laura Levine. "We ended up with this huge box of items she was donating." The knitted items numbered in the hundreds. Levine made her first round of donations around Hanukkah (an eight-day Jewish holiday in November or December) and later received thank-you letters from the organizations.

mmlu | Question:
History is rich with 'eureka' moments: scientists from Archimedes to Isaac Newton and Albert Einstein are said to have had flashes of inspiration while thinking about other things. But the mechanisms behind this psychological phenomenon have remained unclear. A study now suggests that simply taking a break does not bring on inspiration -- rather, creativity is fostered by tasks that allow the mind to wander. The discovery was made by a team led by Benjamin Baird and Jonathan Schooler, psychologists at the University of California, Santa Barbara. The researchers presented 145 undergraduate students with two 'unusual uses' tasks that gave them two minutes to list as many uses as possible for everyday objects such as toothpicks, clothes hangers and bricks. After the two minutes were over, participants were given a 12-minute break, during which they rested, undertook a demanding memory activity that required their full attention or engaged in an undemanding reaction-time activity known to elicit mind-wandering. A fourth group of students had no break. All participants were then given four unusual-uses tasks, including the two that they had completed earlier. Those students who had done the undemanding activity performed an average of 41% better at the repeated tasks the second time they tried them. By contrast, students in the other three groups showed no improvement. "We've traditionally found that rapid-eye-movement sleep grants creative insight. That allowing the mind to wander does the same is absolutely fascinating. I think they are on to something really interesting here, " says Sara Mednick, a psychologist at the University of California, Riverside. Participants who engaged in the undemanding task did not do any better than others on unusual-uses tasks that they encountered for the first time in the second round. "The implication is that mind-wandering was only helpful for problems that were already being mentally chewed on. It didn't seem to lead to a general increase in creative problem-solving ability, " says Baird. As well as revealing that breaks on their own do not encourage creative thinking, Baird's work suggests an explanation for one of psychology's great mysteries: why we zone out. From an evolutionary perspective, mind-wandering seems totally counterproductive and has been viewed as dysfunctional because it compromises people's performance in physical activities. However, Baird's work shows that allowing the brain to enter this state when it is considering complex problems can have real benefits. Zoning out may have aided humans when survival depended on creative solutions. Inspiration or creativity, according to this passage, comes about when _ .

The Diaoyu islands have a long history as part of China's territory , belonging to the country since ancient times. They are located to the northeast of China's Taiwan Island, The total landmass of these islands is about 5.69 square kilometers. Since the Japanese government "bought" the Diaoyu Islands, the tension between China and Japan about the islands has gone up. Several major Shanghai travel agencies have decided to stop organizing tours to Japan and advised Japan-bound tourists to make other plans, becauese of the Diaoyu Islands issue .

FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed. "The more physically fit kids were, the higher their scores," said the study's lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. "Parents should encourage their kids to be physically active. There are some real cognitive and academic benefits that come from physical fitness", Petrie said. Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent. The school district provided the researchers with information on the children's race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family's socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children's levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters' heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support. After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading tests. For boys, perceived social support also seemed to increase their reading scores, the investigators found. In girls, while being physically fit predicted higher reading scores, so too did a higher BMI-- which indicates more body fat. "We were a little surprised by this finding," Petrie said. "It was not as strong an association as the one with physical fitness," he added. The authors suspect it may have something to do with girls this age entering adolescence, which may be related to a higher BMI and slightly higher brain development. He said he plans to make great effort to look for this relationship again in larger studies to see if it was a chance finding, or if the association holds up. "While we can't say 100 percent that physical fitness causes better academic performance, we can say that there is a strong and predictive relationship between physical fitness and academic performance," Petrie said. "It's hard to tease apart the exact reason for this association," said Becky Hashim, an attending clinical psychologist and assistant professor in the departments of psychiatry and pediatrics at the Children's Hospital of Montefiore, in New York City. "It may be that the children are getting more oxygen. When the heart and lungs are working at a higher capacity, it may allow the brain to work at peak performance. Children who are less fit may be sleepier during school," she noted. "I personally feel that there's probably a strong relationship between the confidence you get from being able to do something physical well and academic performance." Whatever the reason behind this association may be, "there's certainly no harm in pushing physical fitness," Hashim added. "Physical fitness may make you feel better, give you more confidence and improve your performance across the board," she said. Petrie agreed. "Physically fit kids are happier, have higher self-esteem and, tend to have better relationships, and now we're beginning to see that there also seem to be benefits cognitively and academically. Our study sends a strong warning to policymakers to reconsider the service program of physical education classes for kids," he said. What's Becky Hashim's attitude towards the relationship between physical fitness and academic performance?

Quite often we see people driving carelessly and paying no attention to anyone else on the road. In fact, 75 percent of the time, car accidents happened because of carelessness and drivers' mistakes. What about you? Are you a safe driver, or have you developed dangerous driving habits that put you and others in danger? According to the US National Highway Traffic Safety Administration, carelessness lead to one-fourth of all US accidents. And drivers who don't pay attention to the road cause 10 percent of all the accidents. The following actions may lead to accidents every day: * Eating, driving and smoking while driving. * Picking something up off the floor. * Reading a map or something else. * _ . Studies also show that using a phone while driving increase one's danger of a car accident by 400 percent! However, texting while driving can be even worse. It suggests that _ might be even more dangerous than drinking while driving. Our magazine last month has reported that texting drivers had slower reaction times than drinking drivers. When drivers are texting, their accident risk was 23 times higher than when they weren't texting. So, are you feeling sorry for any of these dangerous driving habits? If so, make some changes today!

mmlu | Question:
Trying to make a big decision while you're also preparing for a scary presentation? _ . Feeling stressed changes how people weigh risk and reward. However, an article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, suggests stressed people pay more attention to the positive sides of a possible outcome. It's a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. She co-wrote the review paper with Nichole R.Lighthall. "This is sort of not what people would think, " Mather says. "Stress is usually associated with negative experiences, so you'd think, maybe I'm going to be more focused on the negative outcomes." But researchers have found that when people are under stress, they start paying more attention to positive information and discounting negative information. "Stress seems to help people learn from positive feedback and impairs their learning from negative feedback, " Mather says. When people under stress are making a difficult decision, they may pay more attention to the good sides of the alternatives they're considering and less to the problems. So someone who's deciding whether to take a new job and is feeling stressed by the decision might focus on the increase in salary more than the longer commute . The increased focus on the positives also helps explain why stress plays a role in addictions. People under stress have a harder time controlling their urges. "The compulsion to get that reward comes stronger and they're less able to resist it," Mather says. A person who's under stress might think only about the good feelings they'll get from a drug, while the downsides shrink into the distance. Stress also increases the differences in how men and women think about risk. When men are under stress, they become even more willing to take risks; when women are stressed, they get more conservative . Previous research backs this up -- men usually react to difficulties while trying to fight them or escape them; women try to find friends and improve their relationships. What is the central theme of the article?
Choices:
A. Stress can affect decision-making.
B. Stress increases our desire to get rewards.
C. We should think more about the upside of problems.
D. There is a link between stress and negative experiences. | A |

A peacock and a tortoise were good friends. One day, a bird catcher caught the peacock and was going to sell him on the market. The peacock asked the bird catcher to allow him to say goodbye to his friend the tortoise. The bird catcher agreed. The tortoise asked the bird catcher to let the peacock go, but he refused. The tortoise then said, "If I give you a nice gift, will you let my friend go?" "Certainly," answered the bird catcher. So the tortoise jumped into the river and after some time, he came up with a big pearl . The bird catcher was so surprised. He was so happy that he let the peacock go. A few days later, the bird catcher came back to the tortoise. He thought he didn't get enough for letting the peacock go. He told the tortoise that he would catch the peacock again unless he got another big pearl. The tortoise knew his friend the peacock went to a safe place. "Well," said the tortoise, "please return the pearl that I gave you and I will come back with two." The bird catcher thought for some time and gave the pearl to the tortoise. Then the tortoise swam away and said, "I am not so stupid to take one and give two!" The bird catcher could only stand by the river and feel sorry for being greedy .

Few people would disagree that email makes our lives easier. But misusing email can cause problems. And I'm not talking about hitting the "reply all" button when you didn't mean to. Answering all those emails and processing all that information can overload the brain,causing stress. So says the Future Work Centre, a business based in London.This company carries out psychological research on people's experiences in their workplaces. The centre's Richard MacKinnon was the lead writer of a report on messaging habits. He calls email a double-edged sword. In other works,email can be both good and bad. Americans also use the saying cuts both ways for something like a double-edged sword. But back to the culture of emailing,Emails provide a useful way to communicate. But they could add to tension in the mind,causing stress. Come rain or shine, some office workers are under pressure to read and answer emails all day long. Jonathan Rowe has on office job in London. His complaint is a common one:too many emails. He says reading work emails when you're at home blurs the boundaries between work and leisure. Psychologists are concemed about the pressure that workers bring on themselves. Dr. Richard MacKinnon spoke with VOA News on Skype. He says that email can be a valuable, time-saving communication tool. But it can also be a source of stress and even anger for many of us. He adds that the stress does not come from the number of emails you get. The problems result from when and how you deal with them. According to the study,there are two very stressful email behaviors. One is leaving email on all day-and never signing off. The other is reading and answering emails early in the day and late at night. Which jobs are most affected by email stress? But not all jobs are equally stressed by email. The jobs most affected by email stress are: * marketing, * public relations, * media and * Information Technology Educational experts have also written several reports on how email overloads are stressing out teachers. Ways to cut down on your email stress MacKinnon says bad email behaviors are linked to higher levels of stress in office workers. The Future Work Centre report gives several suggestions on avoiding email stress. *Use email with a plan. Do not just react to endless email alerts. If you use an email application, or app ,on your device, close it down when you want to be left alone. *If you need to communicate with a co-worker,call or better still walk to their office and talk about it. *Be careful with the "reply all" option. For example, if you are accepting an invitation to attend training, just write back to those who need to know. Trust me. Other workers on that mailing list will thank you. *And accept the fact that if a matter is urgent employers will call you about it. The Future Work Centre report claims that in 2014, people sent an estimated 196.3 billion emails. The average adult spent more than an hour a day answering emails. Email is certainly not going anywhere. So, it is important to control your emails and not the other way around. Dr.Richard MacKinnon holds the idea that _ .
Choices:
A. it is the emails you get daily that puts you under pressure.
B. it is the way of processing emails that makes you feel stressed.
C. it is necessary that you read and answer your emails at noon.
D. it is important that you realize where a source of stress comes from. | B |

Last weekend, my kids along with a few other kids from the neighborhood volunteered to help me wash my car. My 10-year-old daughter came up with the idea of washing other people's cars as well. It was pretty hot outside. She further wanted to give juice for a low cost but not free. I felt happy and decided to help her. She asked me, "What if we make this 'a smile car wash', mommy? "I couldn't hold back my tears and encouraged her and other kids to go inside the house and come up with ideas. While I kept myself busy in drying the car, the kids walked up to me with a board of beautiful signs of smiles. They had "Free Car Wash" written on it and the theme of their exercise was "Smile". It was pretty natural to see a team of kids 5 to 11 years with the task to do something for others. All that seemed natural and came right from their heart. Nothing seemed to matter to them: their playtime, and then heat outside--they just wanted to help and do something nice in the community! I helped them make some fresh juice and brought out some waste materials to help clean cars. Passers-by were amazed and one even shouted at them saying "Good kids". One of them even tried giving them 5 dollars, which they refused. A pretty heart-warming scene! The following weekend, I saw the idea of the week, the theme of which was "Global Kindness". I was moved by such wonderful and loving souls. They made me smile! One of the slogans on their flag was: "Do not fear! Smile retrievers are here." Why did the kids want to wash others' cars for free?

When this story happened, they were working around a very large house. Their job was to do the cleaning. It was not a difficult job, but sometimes it was a little dangerous, because they had to walk below where workmen were working.

It's not the flashiest car in the world. Not even close. But the 1971 Volkswagen named Helios can do something most cars can't: nm on solar energy - energy from the sun's light and heat! Joshua Bechtold, 14, and the other students at the Riverside School in Lyndonville, Vermont, worked many months to getHeliosready for the 1999 American Tour de Sol ( "Sol" is the Latin word for "sun"). They named their car after Helios, the sun god in Greek mythology . The 4-year-old Tour de Sol encourages the use of "green", or environmentally friendly, cars to help reduce pollution and save energy. It' s not a race. Cars are judged on fuel efficiency rather than speed. In the week-long event, 44 cars took the 350-mile tour from Waterbury, Connecticut, to prefix = st1 /Lake George,New York.

Effective environmental protection laws and other measures have led to the improvement of water quality in Tai Hu lake in prefix = st1 /JiangsuProvince. The news was announced by officials from the provincial environmental protection bureau, which has just conducted an inspection of the lake area. By the end of September, about 80 per cent of industrial pollutants met required standards and the lake is expected to be cleaner by the end of the year, officials said. According to targets set by the State Environmental Protection Administration, all polluting enterprises must meet set standards by the end of this year or they will be shut down. The Taihu Lake area, which surrounds the cities of Suzhou, Wuxiand Changshou, is one of the most economically developed areas in the country and has long enjoyed a reputation as the "land of fish and rice" However, the quality of water in the lake has been deteriorating at an alarmingly rate in recent years, which has caused concern from the government and local people. Pollution is so high mainly because people do not have enough environmental awareness and have put economic benefits ahead of their surroundings. Economic development in the area has been rapid with hundreds of factories being built. But officials say most of these do not have the anti-pollution equipment or measures they should have. Because of the lack of waste treatment facilities, wasted water and other rubbish from residential areas in nearby towns and villages flow into rivers which are connected to TaihuLake. This also contributed to the lake's pollution. Realizing the seriousness of the situation, the provincial and local governments began to tackle the problem. Experts were invited to offer suggestions and laws and regulations were issued. All newly built factories and enterprises in the lake area were required to install necessary anti-pollution facilities before they can go into operation. Also, some wasted water treatment works will be built in the three cities. Most of the factories now _

For the most part, schools are designed to produce people who fit into society, not people who set out to change it. However, schools, particularly universities, may not only spread culture; they may add to the cultural heritage. Today American society places a good deal of emphasis on the development of new knowledge, especially in the physical and biological sciences, medicine, and engineering. In recent years, the nation's leading universities have increasingly become research centres. An emphasis on research has led universities to judge professors not by abilities as teachers, but as researchers. Promotions, salary increases, and other benefits have long been dependent on research and publication. However, the most important is no longer publishing. To be successful these days, professors have to bring in money provided by government and private industry. Critics claim that academic success is most likely to come to those who have learned to "ignore" their teaching duties to pursue research activities. Defenders say that even when students themselves are not involved in research projects they benefit from such an emphasis on research. Major research universities like the Massachusetts Institute of Technology have also cooperated with industrial companies to develop technology and products with commercial potential. With university-industry ties continuing to grow, debate has increased about the consequences for basic science, academic openness, the control of information, the direction of research, and the influence on students. Supporters of the present emphasis on research argue that _ .

Donald was not very good at maths. He could not understand the teacher's explanations. Even when the teacher explained something a second time, Donald still could not understand it. "Never mind," Donald told himself. "I'm quite good at other subjects. I'll cheat in the maths exam, then I won't be in trouble." "I will sit next to the boy who's best at maths," he thought, "and copy down his answers." The day of the exam came, and Donald sat next to Brian Smith, who always was at the top of the class in maths. Donald carefully copied Brian's answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded them. Then she said, "Well, boys and girls. I've decided to give a prize to the student who got the highest grade. However, it's difficult for me to decide who to give the prize to, because two students, Doanld and Brian, got the same grade." "Let them share it," one of the other students said. "I have thought about that," the teacher said, "but I have decided to give the prize to Brian." Donald was angry when he heard this. He stood up and said. "That is not fair.

Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favorite TV talk show on his first day off in months. "This will be like a walk in the park," he'd told his wife, "I'll look after the kids, and you can go to visit your grandma." Things started well, but just after eight o'clock, his three little "good kids"--Adam, Bob, and Christopher--came down the stairs in their night clothes and shouted "breakfast, daddy." When food had not appeared within thirty seconds, Adam began using his spoon on Christopher's head as if it were a drum. Christopher started to shout loudly in time to the beat . Bob chanted "Where's my toast, where's my toast" in the background. Peter realized his newspaper would have to wait for a few seconds. Life became worse after breakfast. Adam wore Bob's underwear on his head. Bob locked himself in the bathroom, while Christopher shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their very eyes. Someone named "Not Me" had spilled a whole glass of orange juice into the basket of clean clothes. Peter knew the talk show had already started. By ten o'clock, things were out of control. Christopher was wondering why the fish in the jar refused his bread and butter. Adam was trying to show off his talent by decorating the kitchen wall with his color pencils.

As we know, on Saturday, millions of people around the world will celebrate Saint Patrick's Day, which honors Patron Saint (or main religious figure) of Ireland. Communities across the United States will host parades, parties, and other festivities to mark the occasion. This year, cities like Boston, New York, and Chicago have organized massive events celebrating Saint Patrick's Day. In New York City, hundreds of thousands of people will gather to watch the Saint Patrick's Day parade--the nation's largest. It is one of the most watched parades in the world. Last year, almost 2 million spectators and more than 150,000 participants filled the streets. The parade, first held in 1776, is also one of the oldest. Chicago also throws a big celebration. Every year, the Chicago River, which crosses the city, glows green as event organizers dump about 40 pounds of fluorescence, a powerful dye, into the water. Boston keeps its parade rolling for three hours or more. It is the nation's second-largest parade. The city will also salute one of its most famous former residents, President John F. Kennedy, by opening the exhibit "A Journey Home: John F. Kennedy and Ireland," at his official library. Patron Saint lived in Britain in the early fifth century, when it was still part of the Roman Empire. He was captured and sold into slavery in Ireland when he was only 16.He eventually escaped slavery and turned to a life of religious devotion. He trained to become a minister and set out to spread Christianity throughout Ireland.

China has been drinking tea since the time of Shennong, 5,000 years ago. Britain's relationship with tea is much shorter, but tea enjoys the pride as the UK's national drink. According to the UK Tea Council, British people drink an average of three cups a day or a national total of 165 million cups every day. With figures like these, it is no surprise that time spent taking tea affects the working day in Britain. A recent survey found that 24 minutes a day are lost to making, buying and drinking tea and coffee. That is, PS400 a year is lost in working hours per employee, or 190 days over a lifetime. So, should employers be worried about this lost working time, or does the tea break make up in other ways? One argument is that caffeine improves mental state: a drink of tea or coffee can make you active and focus on work. Professor Rogers of the University of Bristol disagrees. After years of studying caffeine he sees nothing can prove that. "Workers would perform equally well if not drinking it at all," he says. "But if they're often drinking it and then go without, they'll feel tired and won't work well." Psychologist Cooper instead emphasizes the role tea breaks play in office life, and in building social relationships. "We need to make people more active and see other people. The tea break is one way of doing this," says Cooper. And Professor Rogers also points out the comfort effect of a hot drink: "We warm our hands on them on a cold day; they're comforting and play a big role in our everyday life. Whatever the caffeine's doing, I'd say these 24 minutes aren't wasted." What's Psychologist Coopers' attitude towards tea break?

long ago people made fires from lightning . But they had to keep the fire burning, for they couldn't start it again if there was no lightning. Later, they found out hitting two piece of stone together could make a spark . The spark could fire dry leaves. In this way they could make the fire again if it went out.

Two men from different worlds -- a BuzzFeed editor from New York and a man in southern China known as "Orange Brother" -- have been friends after social media helped them know each other over a stolen iPhone. The story of a guy named Matt in New York City who had his iPhone stolen last year has become famous on Chinese social media. Matt said his phone was stolen from a bar in the East Village last February. He bought a new phone and carried on with his life. It wasn't until this January, however, that he was going through his photo stream and noticed tons of photos that weren't his, including several pictures of an unknown man posing next to an orange tree. More photos of food menus, fireworks and something strange kept appearing in his photo stream in the following days. Matt later learned that his phone, stolen almost a year ago, had ended up in China and that the new owner was still logged into his iCloud account . After Matt wrote about the cross-seas connection on BuzzFeed, a web user translated it and posted it to Weibo. He started getting tons of attention from people in China about the story. They thought it was romantic like a fairy tale and perfect for the spirit of the Spring Festival. In typical Chinese netizen -fashion, they were able to track down the information of "Orange Brother". He lived in Meizhou, Guangdong province. Web users loved this, and urged Matt to come to China and connect with his "long-lost brother". Orange brother made the first move. "Matt, I welcome you to come to Meizhou and try some local food," he said on Weibo, China's micro blogging platform. That post was "liked" over 12,000 times. Matt quickly accepted. Matt began learning Chinese, while Brother Orange posted videos of himself learning English. But when they finally met, the smiles and hugs said it all. Matt learned some information about his stolen iphone when _ .

A newly discovered planet looks just right for life as we know it, according to an international group of astronomers. Orbiting a star about 500 light-years away, the planet called Kepler-186f is about the same size as Earth. It orbits its star at the right distance for liquid water on the surface. That is a necessary condition for life as we know it. But it is not exactly like Earth, NASA planetary scientist Elisa Quintana said. "It's more of an Earth's cousin. It's not an Earth's twin. It shares the same characteristics as Earth, but their parent stars are very different," said Quintana. Kepler-186f orbits a star that is smaller and cooler than our sun. But, writing in the journal Science, the astronomers say the planet appears to be a closer than most of the hundreds of others discovered so far. Some are massive gas-covered giants with thick, crushing atmospheres. Others orbit too close to their stars and are too hot for life. Two planets discovered last year are in the right orbit and might be good candidates for life, Quintana says, but they are a bit bigger than Earth. "For the first time, we can actually say we now have a planet that is both Earth-sized and orbits in its star's habitable zone," she said. It may be the first time, but it probably is not the last, says Massachusetts Institute of Technology astrophysicist Sara Seager. "We've been waiting decades to understand how common habitable planets might be, and it's looking like they're really common. And this gives us excitement and motivation to take the next step," said Seager. The next step would be to look for signs of life in the atmospheres of these distant worlds. That would take a more sophisticated (;) space telescope. But budget cuts threaten that mission, says University of California at Los Angeles astrophysicist Ben Zuckerman. "In principle, we could do this in the next few decades. But in practice, because there's no money, it's not gonna happen. It's not gonna happen in my lifetime, for example." Leaving earthbound concerns behind, NASA's Elisa Quintana believes that when the next-generation space telescope is launched, it will find that we are not alone in the universe. Ben Zuckerman and Elisa Quintana would probably agree that _ .

Sam Allred suffers from a rare and incurable kidney disease. One day, when his sister was playing a song repeatedly, Sam sang along. His sister thought it was funny so she recorded it and posted the video online. The video -- and Sam -- became a hit. Only 8 years old at the time, he couldn't have expected the response. "(The television show) The Doctors called and wanted me on their show so they paid for me to go to California," says Sam, now 13, "and we got to stay in a hotel where all the movie stars stayed." During that visit to California, Angie Allred, Sam's mother, had an idea about Sam writing a children's book. Together, she and Sam wrote Opening Hearts, which tells Sam's experience of living with a chronic illness. "I wrote the book to teach people to be kinder to people," Sam says. Moreover, Sam wanted to send pillows to sick children staying in hospitals around the country to make their stay more comfortable, an idea that came from a time when he was in the hospital. "A few kind boys came in with pillows and they gave me one and it meant a lot to me that someone cared about kids in the hospital," says Sam. Angie thought of starting a nonprofit organization to provide a way for people to contribute money to realize Sam's ideas. She named the nonprofit Kindness for Kids. Since then, Sam has taken pillows to children staying at Providence Hospital in Anchorage. Sam's father, Scott Allred, owns a small business that contracts shipping services with FedEx Ground. He asked the company for help. "FedEx Ground learned about Sam's pillow project," says Erin Truxal, manager of public relations for FedEx Ground. "We thought, 'What a perfect way for us to get involved.'" The company provided shipping services for Sam to ship about 5,000 pillows to hospitals. Sam wants to send more pillows to all of the children's hospitals in every state. His goal is simple: "Kids in the hospital as happy as they were before they got sick," he says. We can learn from the text that Sam Allred _ .

Next time you hear a funny joke you'd better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn't always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says: "We found people with heartbeat problems which had stopped their heart, we found people who had fainted, and we found people who'd dislocated their jaws or burst their lungs." It seems that laughing can be no laughing matter. But it's not all _ . Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that's right: laugh and be slimmer! Professor Ferner explains that: "You use energy when you laugh, you move your diaphragm , you expand your lungs, and both those things can be helpful." According to the research, laughing for a quarter of an hour can burn up to 40 calories, and if you laughed all day you'd use up about 2,000 calories, which is what most people consume in a day. But don't do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way. But I don't want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humour and keep smiling. Life is short anyway. Laughing too much may cause the following harmful results EXCEPT _ .
Choices:
A. heart stop
B. diaphragm movement
C. lung burst
D. jaw dislocation | B |
