mmlu | Question:
One morning, Ann's neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day. Tracy took photos of the dog and printed off 400 FOUND fliers , and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann's son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old. Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, Riley dashed into the boys' room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent. "If it hadn't come to get me, the doctor said Jack would have died," Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it. The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, "That dog saved my friend's son." Peter drove to Ann's house to pick up his dog, and saw Thomas and Jack crying in the window. After a few moments Peter said, "Maybe Odie was supposed to find you, maybe you should keep it." How did the dog help save Jack?

mmlu | Question:
Dear Mayor, I would like to draw your attention to the depressing state of the environment in our city. Increased vehicles have made the air polluted. Citizens find it difficult to breathe. Dumping toxic chemicals into the river has polluted the drinking water and ground water. All of us, as concerned citizens, have discussed these problems in various meetings. We have come up with the following proposals . The green roads are no longer green. Many trees and bushes have been cut. We propose restricting the movement of vehicles. Besides, we should make it compulsory to use anti-pollution devices on all vehicles. We should also plant more plants and trees along roads. The Bada Nadi River has become a dumping ground of toxic chemicals from some factories. These toxic chemicals have killed nearly all the life in the river and polluted our drinking water and ground water. We propose that the Bada Nadi River be declared a protected water body. All the dumping should be banned and heavy fine should be imposed on the offenders . To _ the problem of managing toxic waste, we propose setting up a water treatment plant so that only clean water is discharged into the river. Cleaning up the river and introducing various fishes and plants to the river will bring it back to life. Lastly, the noise pollution caused by honking horns and blaring loudspeakers has caused distress to one and all. Many people have suffered from noise-related illnesses. We propose a blanket ban on the use of loudspeakers. And"no horn zones"should also be declared in residential hospitals and school areas. I would request you to seriously consider our proposals and act accordingly. Thank you! Sincerely yours, A kind-hearted citizen In order to protect the Bada Nadi River, the author suggests _ .

Irina,now 46,never imagined she'd one day make a living as a balloon artist.The daughter of an engineer and a teacher,she won top academic awards in high school,went on to medical school and became an emergency room physician in a small city. "I loved the science of medicine," she says today,"but being a doctor was very hard.I saw things people don't normally see--women giving birth in the street,people getting drunk and killing someone." Medications were scarce,making it very difficult to treat those in need.When Irina was 33,a girlfriend showed her a magazine photo of an American named Wes Patterson.They began exchanging letters,and married that December.Irina took a public relations job.Then,a few years ago,she watched a man at a party twist a skinny balloon into the shape of a dog. _ Irina soon purchased a tiny pump and a supply of balloons and began practicing on the sidewalks.Observers challenged her to create all kinds of figures.Now,Irina says,"There's nothing I can't make."

mmlu | Question:
I've spent over a year in India, and in those 365 plus days, I've learned a lot about getting around Indian cities. My biggest lessons have been learned through being cheated, particularly by taxi and rickshaw drivers, but that doesn't mean those are bad ways to travel, as long as you know what you're doing. Below are the best ways to get around the city of Delhi, India, and tips for how to keep from being the victim of scams . Taking taxis is a great way to get around the city of Delhi and chances are, if you arrive in Delhi by plane, as soon as you make it through customs, you'll be swarmed by Indian taxi drivers. At the Delhi airport, be sure to arrange for a taxi to your hotel at one of the two Delhi Traffic Police Taxi Booths. One is inside the airport, and one is outside. The key is to make sure to go to a booth run by the police, rather than by independent taxi drivers. Rickshaws are one of my favorite ways to get around Indian cities, partly because it's how the locals often travel. Auto-rickshaws are more common, but bicycle rickshaws are still used in Old Delhi. If you do have a chance to take a bicycle rickshaw, you should do it at least once for a unique experience that should only set you back about 15 rupees. Auto-rickshaw rates around Delhi range between 30 and 80 rupees, depending on distance. If you really want to travel around Delhi like the locals, take a public bus. Indian buses become very crowded and most do not have air conditioning. They are, however, very cheap. A bus trip won't set you back any more than 15 rupees, as long as you stay within the city limits. Since Indian buses get so crowded, try to board the bus at the start of the route so you can get a seat. The train is a great way to get around within the city of Delhi. Fares are reasonable, between six and 22 rupees. All departure announcements are in both Hindi and English, and tokens can be purchased for between six and 22 rupees. What is the author trying to do through this text?
Choices:
A. Expect us to travel around Delhi.
B. Show his/her experiences in Delhi.
C. Give some advice of traveling in Delhi.
D. Explain the difficulties of traveling in Delhi. | C |

Tu Youyou, an 84-year-old scientist, became the first female Chinese to win a Nobel Prize in science on Oct,5. She shared the 2015 Nobel Prize for medicine because of the new medicine for malaria . Tu started the research in the 1970s that made her find artemisinin , a kind of medicine that has saved many people's lives. It comes from Chinese traditional medicine and now is a good way to treat malaria. When the news came that Tu was given the prize, there were cheers as well as questions. Some said that her achievement was the result of lots of Chinese scientists working together. So it is unfair to give the prize only to Tu. However, Tu was awarded for "three firsts". She was the first to bring artemisinin to her team, the first to extract artemisinin that can stop malaria, and the first to finish the experiment. Giving prizes to scientists with great ideas is the best way to keep national innovation . What kind of illness can artemisinin be used to treat?
Choices:
A. cold
B. flu

mmlu | Question:
Six-month-old babies are strictly limited in what they can remember about the objects they see in the world. If you hide several objects from babies, they will only remember one of those objects. But a new study, which was published in an issue of Psychological Science, a journal of the Association for Psychological Science, finds that when babies "forget" about an object, not all is lost. Researchers used to think that babies less than two years old did not understand that an object continues to exist when it is not in the baby's view. But in mid-1980s, new ways of doing experiments with babies found that they do, in fact, know that objects don't disappear when they do not look at them -- a concept known as object permanence. But it was still unknown what babies needed to remember about objects in order to remember their existence. Now Melissa Kibbe, of John Hopkins University, and Alan Leslie, of Rutgers University, are working to figure out exactly what it is that babies remember about objects. For the new study, they showed six-month-old babies two objects, a disk and a triangle. Then they hid the objects behind small screens, first one shape, then the other. Earlier research has shown that young babies can remember what was hidden most recently, but have more trouble remembering the first object that was hidden. Once the shapes were hidden, they lifted the screen in front of the first object. Sometimes they showed babies the shape that was hidden there originally , but sometimes it was the other shape, and sometimes the object had _ completely. Psychologists measure how long babies look at something to see how surprised they are. In Kibbe and Leslie's study, babies weren't particularly surprised to see that screen had changed, for example, from a triangle to a disk. But if the object was gone altogether, the babies looked significantly longer, indicating surprise at an unexpected outcome: "This shows that even though babies don't remember the shape of the object, they know that it should continue to exist," Kibbe says. "They remember the object without remembering the features that identify that object." This helps explain how the young brain processes information about objects, Leslie say. He thinks the brain has a structure that acts like a kind of pointer, a mental finger that points at an object. Before the study, which of the following was unclear?
Choices:
A. Whether babies know objects are gone.
B. What made babies remember objects' existence.
C. Whether babies can remember what was hidden first.
D. Why babies were interested in what was hidden. | B |

mmlu | Question:
What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives. (words:353) According to Theory Second, the disaster happened to the Titanic mainly because _ .
Choices:
A. the freezing weather made the watcher not be able to watch clear
B. the mirage on the sea attracted the watcher and made him forget his work
C. the high tides drove the icebergs float so fast that the watcher didn't respond to them

mmlu | Question:
Several decades ago, US sociologists developed a series of universal facial images supposed to represent the seven basic human emotions: happiness, sadness, surprise, fear, disgust, anger and neutrality . But now, a new study by researchers at the University of Glasgow indicates that these standardized facial images aren't so universal at all. For the study, the Scottish researchers found 13 Western Caucasians (mainly Europeans) and 13 East Asians (mostly Chinese students). The volunteers were shown the standardized facial images and asked to identify the emotions being expressed. At the same time, the researchers electrically monitored the eye movements of the volunteers. According to the results, published in the journal Current Biology, the Asian participants had a harder time than the Caucasians telling the difference between a face meant to look fearful compared with one showing surprise, and a face supposedly expressing disgusting compared with one displaying anger. "This strongly suggests that the meanings of facial expressions are different across cultures," says Rachael Jack, who led the study. The study also showed that the volunteers focused on different parts of the face in their efforts to understand the underlying emotions. "Westerners look at both the eyes and the mouth to the same degree, yet Easterners favor the eyes and overlook the mouth. This means that Easterners has difficulty distinguishing facial expressions that are similar around the eyes," Ms Jack says. The faces representing fear and surprise" both have big, wide open eyes, while the mouths are very different," she notes. "It would be difficult to distinguish between the two if you didn't look at the mouth." So why would different cultures express emotions in different ways? Ms Jack thinks it may be considered impolite in some Asian cultures to display certain emotions in an obvious manners, and that they use more subtle ways to express them. In particular, muscle movements around their eyes could be more important for expressing feelings than over-expressive mouth movement, explaining why the Asian participants focused on the eyes. The Asian volunteers may have focused on the eyes because _ .
Choices:
A. Easterners believe using the eyes to express feelings is the best way
B. it's polite to focus on other people's eyes in some Asian countries
C. Easterners tend to use the eyes to express their emotions

mmlu | Question:
The virus "Ebola" is named after the Ebola River in what is now the Democratic Republic of the Congo. That's where the virus was discovered in 1976. A person can only get Ebola through direct contact with an infected person's bodily fluids, for example, sweat or spit. Additionally, the virus can get into your body through your eyes and mouth if those areas come into contact with something that contains the bodily fluids of an infected person. That's why health care workers are supposed to keep themselves completely covered while treating patients. The deadliest Ebola outbreak is spreading fast in Western Africa, taking over 900 lives so far. The health systems in Guinea, Sierra Leone and Liberia are severely lacking in resources, and health care workers may not have access to adequate protective clothing when working in rural clinics, where the proper protections are lacking. Since Guinea, Sierra Leone and Liberia share a border; it's easier for people to move from one country to another, increasing the risk for disease spread. For now, all doctors can do is treat the symptoms and provide supportive care like monitoring heart rate, blood pressure, and breathing while making sure the patients' fluids are supplied. Sometimes patients are given antibiotics to treat other possible infections. The hope is to make the patient pull through the infection so their immune system can eventually clear the virus. The people who survive Ebola have created enough antibodies to kill it. There are several promising drugs and vaccines in development, but since Ebola is less common--and research about it is not well funded -- there is no drug or vaccine that has been approved for use in humans. Many of the other drugs and vaccines have not yet been tested in humans. The WHO (World Health Organization) is meeting next week to discuss whether experimental treatments should be used during this outbreak. Which is the possible reason why Ebola spreads in West Africa quickly?
Choices:
A. The Ebola river is polluted by the virus.
B. There aren't any protections.
C. The protective clothing is adequate.
D. Three western countries share a border. | D |
mmlu | Question:
For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives. "A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?" asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts. These parts are not made of steel; they are the real things --- living cells, tissue, and even organs. Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999,when a research group at North Carolina's Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs from kidneys to ears. The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient's body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient's own cells and will not be rejected by the body's immune system. Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala's medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney. So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals' chances of survival. What have scientists experimented successfully on for a bioartificial kidney?

A. Patients.
B. Rats.
C. Sheep.

mmlu | Question:
Blogging may have psychological benefits for teens suffering from social anxiety, improving their self-esteem and helping them relate better to their friends, according to new research published by the American Psychological Association. "Research has shown that writing a personal diary and other forms of expressive writing are a great way to release emotional distress and just feel better," said the study's lead author, Meyran Boniel-Nissim, PhD, of the University of Haifa, Israel. "Teens are online anyway, so blogging enables free expression and easy communication with others." Blogging has a stronger positive effect on troubled students' well-being than merely expressing their social anxieties and concerns in a private diary, according to the article published online in the APA journal Psychological Services(r). Opening the blog up to comments from the online community intensified those effects. The researchers randomly surveyed high school students in Israel, who had agreed to fill out a questionnaire about their feelings on the quality of their social relationships. A total of 161 students -- 124 girls and 37 boys, with an average age of 15 -- were selected because their scores on the survey showed they all had some level of social anxiety or distress. All the teens reported difficulty making friends or relating to the friends they had. The researchers assessed the teens' self-esteem, everyday social activities and behaviors before, immediately after two months and after the 10-week experiment. Four groups of students were assigned to blog. Two of those groups were told to focus their posts on their social problems, with one group opening the posts to comments; the other two groups could write about whatever they wanted and, again, one group opened the blog up to comments. The number and content of comments were not evaluated for this experiment. The students could respond to comments but that was not required. Two more groups acted as _ -- either writing a private diary about their social problems or doing nothing. Participants in the writing and blogging groups were told to post messages at least twice a week for 10 weeks. Four experts, who held master's or doctoral degrees in counseling and psychology, assessed the bloggers' social and emotional condition via their blog posts. Students were assessed as having a poor social and emotional state if they wrote extensively about personal problems or bad relationships or showed evidence of low self-esteem, for example. Self-esteem, social anxiety, emotional distress and the number of positive social behaviors improved significantly for the bloggers when compared to the teens who did nothing and those who wrote private diaries. Bloggers who were instructed to write specifically about their difficulties and whose blogs were open to comments improved the most. All of these results were consistent at the two month follow-up. The authors conceded that the skewed sex ratio was a limitation to the study. However, the researchers analyzed the results separately by gender and found that boys and girls reacted similarly to the interventions and there were no major differences. They said future research should attempt to control the subjects for sex. What is the main idea of the passage?
Choices:
A. Blogging can help reduce social stress and anxiety.
B. The research into blogging attracts public attention.
C. Blogging provides a simple way for communication.
D. Blog comments have a positive effect on teenagers. | A |

A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth. Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience--what psychologists call fluid intelligence--is innate and cannot be taught(though people can raise their grades on tests of it by practicing). But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works. The key, researchers found, was carefully structured training in working memory--the kind that allows memorization of a telephone number just long enough to dial it.This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence. First they measured fluid intelligence of volunteers using standard tests.Then they trained each in a complicated memory task--the child's card game,in which they had to recall a card they saw and heard.During the course, they needed to ignore irrelevant items, monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time. The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively.To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training. The results, published Monday in The Proceedings of the National Academy of Sciences,were striking.Improvement in the trained groups was a lot greater.Moreover,the longer they trained, the higher their scores were.All performers,from the weakest to the strongest,showed significant improvement. "Our results show you can increase your intelligence with proper training." said Dr Jaeggi, a co-author of the paper."No one knows how long the gains will last after training stops," he added, "and the experiment's design did not allow the researchers to determine whether more training would continue to produce further gains." .When the experiment was conducted, the researchers _ .

A. trained the four groups for the same period of time

Swimming in the water of Hawaii's Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction . Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays . Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they're swimming in the water. From 2010 to 2013, spinner dolphins of Hawaii's Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia's Murdoch University. The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals. Besides, when people are around, dolphins become more active. Thus, they can't get enough sleep. "Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population," Ann Garrett of NOAA's National Marine Fisheries Service told the Associated Press. As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state. What does the article mainly talk about?
Choices:
A. What habits dolphins have.
B. What spinner dolphins are.
C. How the animals live in the sea.
D. How to protect dolphins near the shore. | D |

One day, a magician came to the palace and asked for sanctuary , saying that he was a professor who was being persecuted by his enemies and had nowhere to write an important book. "Good professor," said the king, "you shall have a room and everything that you desire, on condition that you may finish your great work." So the magician went on with his spells and magic formulas, pretending to be absorbed in scholarly matters. Every Friday, which was the day of rest in that far land, the magician paid his respects to the king and his court, but secretly he desired to take away the king's throne. One day he disguised himself as an old woman and walked under the trees in the palace gardens till he met Safia. "Princess," he said, "let me be your laundress, for I can wash linens and silks as finely as anyone in the world, and I would do it for almost nothing if I could serve Your Highness." "Good woman," said Princess Safia, "I can see that you are a poor creature and grieve for your condition. Come to my private quarters and I shall give you some of my linen to wash." So the disguised magician followed the princess into the palace, and before the girl could see what was happening he bundled her into a laundry bag and ran away as fast as his legs would carry him. He took the princess into his private room. Muttering a magic spell, he made her as small as a doll, and put her in a cupboard.

The Puritans get a bad reputation in America--especially when it comes to alcohol. Mayflower, the first ship that came over from England to Massachusetts Bay, actually carried more beer than water.In fact the Founding Fathers of America liked a drink--Samuel Adams was a partner in his father's brewery, and Thomas Jefferson was famous for importing European wines. Early Americans took a healthful small drink for breakfast, whiskey was a typical lunchtime drink, ale accompanied supper and the day ended with another drink called nightcap.Most Americans in 1790 consumed an average of 5.8 gallons of pure alcohol a year.In 1830, consumption reached 7.1 gallons a year and alcoholism was starting to have a serious influence on communities.Women and children might be in physical danger if the man of the house began drinking.If he became ill or lost his job through drinking, there was no social safety net to support or protect his family.Eventually, alcoholism was being treated as a disease. By the late 19th Century, support for Prohibition, banning the manufacture and sale of alcohol, was powerful.The first arrest for driving under the influence of alcohol was in 1897.On 16 January 1919, Prohibition was set into law.However, by the 1930s when American economy was experiencing a hard time it was widely believed that making alcohol legal again would provide badly-needed jobs and taxes.So in February of 1933, Prohibition was endeD. Still, Prohibition had a great influence on alcohol drinking in this country.In 1955, Americans drank an average of 2.3 gallons of pure alcohol a year.The Prohibition movement was still quite strong after Prohibition ended and it led to a lot of local prohibition on alcohol. The American presidency has done a lot to rehabilitate alcohol and make it respectable again.Presidents Richard Nixon, Jimmy Carter, Bill Clinton, Ronald Reagan and Barack Obama can all be seen on film drinking socially and making official toasts with international celebrities.

I'm a speed reader. Have been since I was a teen. Mother worked for the continuing education department of a university, and they were offering a class on speed reading and needed one more person to fill out the class. I became that one person. The class met for only an hour or two for a few weeks, but when the goal of a class is speed, you don't need to meet for long. The instructor said to make our eyes go across the lines of words as fast as they could and not to be concerned about what the words meant. I read Animal Farm in 10 ten minutes. Cover to cover. The instructor asked what the book was about. I said I didn't know, but if I had to guess I'd say it was about animals on a farm. He looked displeased. I've been speed reading ever since. I can't stop and I can't slow down. Today, for example, I plan on reading Churchill's History of the English Speaking Peoples over lunch. I hope it's more memorable than Animal Farm. As a result of all this speed-reading, I often experience a delay between what I think I read and what something actually says. The other day I passed by a mall with a large sign that said "Auto Theft Sale". I thought how efficient it was for auto thieves to simply sell all the stole cars in a big tent at the mall. A half-mile later it dawned on me that the sign had said "Auto Tent Sale". Every time I drive through a construction zone, I gasp . The sign says: "Hit a Worker $10, 000 (about 62,000 yuan)." It reads like they're offering a reward. Of course, it's not an offer. It's just that my eyes rarely take in the last line that says, "Fine." It's a $10, 000 fine if you hit a worker. Someone really needs to rephrase that one. Speed reading has bitten me on the backside more than once. Especially as a writer. Just ask any of my editors. Why was the author able to attend classes on speed reading?
Choices:
A. Her mother found her gifted in speed reading.
B. She was the only teenager applicant for the class.
C. She'd already practiced speed reading before.
D. She took a chance and filled one vacancy . | D |

BEIJING (AP) -- Sandstorms whipping across China shrouded cities in an unhealthy cloud of sand Monday, with winds carrying the pollution outside the mainland as far as Hong Kong and Taiwan. It was the latest sign of the effects of desertification: Overgrazing, deforestation, urban sprawl and drought have expanded deserts in the country's north and west. The shifting sands have gradually moved onto populated areas and worsened sandstorms that strike cities, particularly in the spring. Winds blowing from the northwest have been sweeping sand across the country since Saturday, affecting Xinjiang in the far west all the way to Beijing in the country's east. The sand and dust were carried to parts of southern China and even to cities in Taiwan, 1600 miles (2600 kilometers) away from Inner Mongolia where much of the pollution originated. The sandstorm in Taiwan, an island 100 miles (160 kilometers) away from the mainland, forced people to cover their faces to avoid breathing in the grit that can cause chest discomfort and _ problems even in healthy people. Drivers complained their cars were covered in a layer of black soot in just 10 minutes. In Hong Kong, environmental protection officials said pollution levels were climbing as the sandstorm moved south. Twenty elderly people sought medical assistance for shortness of breath, Hong Kong's radio RTHK reported. The latest sandstorm was expected to hit South Korea on Tuesday, said Kim Seung-bum of the Korea Meteorological Administration. The sandstorm that raked across China over the weekend caused the worst "yellow dust" haze in South Korea since 2005, and authorities issued a rare nationwide dust advisory. Grit from Chinese sandstorms has been found to travel as far as the western United States. China's Central Meteorological Station urged people to close doors and windows, and cover their faces with masks or scarves when going outside. Sensitive electronic and mechanical equipment should be sealed off, the station said in a warning posted Monday on its Web site. State television's noon newscast showed the tourist city of Hangzhou on the eastern coast, where graceful bridges and waterside pagodas were hidden in a mix of sand and other pollution. In Beijing, residents and tourists with faces covered scurried along sidewalks to minimize exposure to the pollution. A massive sandstorm hit Beijing in 2006, when winds dumped about 300,000 tons of sand on the capital. Which of the following statements is NOT true?
Choices:
A. South Korea seldom issues nationwide dust advisories.
B. Taiwan is 1,600 miles from Beijing.
C. Sandstorms have hit Beijing more than once.
D. In Hong Kong some old people need help for shortness of breath caused by sandstorms. | B |

On October 11, NASCAR announced the car of tomorrow after a seven-year design program. People used to believe that science would promise a future of endless spare time and very cheap electricity. Nowadays the scientists' predictions are a great deal less optimistic: the world is challenged by climate change and decreasing resources. In fact, the car of tomorrow is a symbol of hope. The emission of carbon dioxide has contributed to global warming, but the car producers are waking up to their responsibilities. Investment in new technology to maximize efficiency and minimize environmental damage is not only improving the car industry's act but also setting an example to other industries. It is said that most cars of today run about 15 percent efficiency, which does highlight the potential for improvement. Get it right, and we could continue to enjoy the freedom that comes with owning a car, without the worries. Of course, many advances have already been made. There's evidence that the public is eager to buy cleaner and greener cars. And with petrol prices increasing there is no doubt that the cars with economical, efficient engines are going to be in great demand. The good news is that we can all drive the car of tomorrow today, without having to worry about the purchase cost. By choosing our holiday hired cars wisely we can cut down on our fuel costs and experience an eco-friendly drive. Hire a green car and you'll make a difference to the environment. Designers will always enjoy catching our imagination with "concept cars" that look more like miniature spaceships than anything you see on the highway. Whether these creations will eventually become family cars remains to be seen. However, for the moment, there's no doubt at all what the car of tomorrow will be, and it's here today: something familiar and friendly that does its job with considerably less trouble and much greater efficiency than the car of yesterday. According to the text, people's present worry about developing the car industry is that _ .

The hole in the earth's protective ozone layer won't repair itself until about two decades later than had been expected, scientists announced. The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation , helping to make life on Earth possible. For many dacades, ozone was depleted by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere. Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere over the past 27 years. The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed. Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate ozone-depleting gases over Antarctica, and how _ will decrease over time, reducing the ozone hole area. Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065. The improved computer model is believable because _

Agatha Christie (1890-1976) was born Agatha May Clarissa Miller in Devon, England in 1890, the youngest of three children in a conservative, well-to-do family. Taught at home by a governess and tutors, as a child Agatha Christie never attended school. She became skillful at creating games to keep herself occupied at a very young age. A _ l child, unable to adequately express her feelings, she first turned to music as a means of expression and, later in life, to writing. In 1914, at the age of 24, she married Archie Christie, a World War I fighter pilot. While he was off at war, she worked as a nurse. It was while working in a hospital during the war that Christie first came up with the idea of writing a detective novel. Although it was completed in a year, it wasn't published until 1920, five years later. "The mysterious Affair at Styles" gave the world the unique Hercule Poirot, a retired Belgian police officer who was to become one of the most enduring characters in all of fiction. With his waxed moustache and his "little grey cell," he was "meticulous (careful to do things correctly), a tidy little man, always neat, orderly and a bit absurd." Christie wrote more than 30 novels featuring Poirot. Among the most popular were" The Murder of Roger Ackroyd"(1926), "Murder on the Orient Expredd"(1934), and "Death on the Nile" (1937). Another of Christie's most well-known and beloved characters was introduced in "Murder at the Vicarage" in 1930. Miss Jane Marple, an elderly single in the old- fashioned English village of St. Mary Mead, solved all manner of mysteries with intense concentration and instinct. Christies ultimately (finally)became the acknowledged Queen of the Golden Age. In all, she wrote over 66 novel, numerous short stories and screenplays, and a series of romantic novels using the pen name Mary Westmacott. Several of her works were made into successful feature films, the most notable being Murder on the Orient Express (1974). In short, she is the single most popular mystery writer of all time. In 1971 she was awarded the high honor of becoming a Dame of the British Empire. Which of the following is NOT true about Hercule Poirot?
Choices:

The computer is fast, and never makes a mistake, while people are too slow, and full of mistakes sometimes. That's what people often say when they talk about computers. For over a quarter of a century, scientists have been making better and better computers. Now a computer can do a lot of everyday jobs wonderfully. It is widely used in factories, hospitals, post offices and airports. A computer can report, decide and control in almost every field. Many computer scientists are now thinking of making the computer "think" like a man. With the help of a person, a computer can draw pictures, write music, talk with people, play chess, recognize voices, translate languages and so on. Perhaps computers will one day really think and feel. Do you think the people will be afraid when they find that the computer is too clever to listen to and serve the people? What will happen in the future?
Choices:
A. Most jobs will be done by the computer.
B. People will no longer use computers.
C. Computers will be used only to talk with people.
D. All computers will be put into prison. | A |

For most Chinese university students, the prefix = st1 /USis a favorite destination for further education. But apart from obstacles such as the GRE and TOEFL exams, choosing a good graduate school is no easy task. Admission is very competitive for international students, so it is important to apply to a number of institutions to have a reasonable chance of acceptance. Since the application to most universities requires a certain fee, Chinese students usually choose seven to 17 universities according to their own financial circumstances. Wang Yuwei, a Zhejiang University graduate, sent applications to 15 USuniversities. When the 24-year-old began looking for a USgraduate school in her senior year, she took time to compare the various schools and find the ones most suiting her needs. Now, studying at theUniversityofWashington, she knows that her hard work paid off. "To broaden your chances, at least one third of the applications should be to less selective schools," said Wang. "Applicants shouldn't limit their choices to the most famous institutions." Furthermore, one shouldn't rely on too much on college rankings such as the Gorman Report or US News & World Report's annual league tables. The right school is the one that best meets your own personal needs and interests, rather than someone else's assessment of an institution's prestige . "Usually choices are based on one's personal interests and academic background, but it is important to make sure that your chosen subject is satisfied," said Wang. According to this passage, what can we judge?
Choices:
A. More and more students will go abroad for their further education.
B. Choosing a good graduate school is a piece of cake.
C. To go abroad for further education, you must pass the GRE or TOTEL.
D. To get a better chance to go abroad, you'd better apply to a less selective school. | C |

I have never understood why so many people visit Rome from late spring to early autumn, when traffic, heat and stressed shopkeepers and waiters lead to the lower tone of the city. Things improve a little in March, April, October and November. But connoisseurs know that winter is the best time to go there. In winter, the low-flying sun turns Rome into a wonderful stage set. There are days in winter when the sky is kind of blue. And there are also days when you find that you have beautiful sights all to yourself. Perhaps the only period you might want to avoid is the two weeks before Christmas. Italians often leave their shopping late, and traffic in the city is often heavy. But this can also be a good time to come if you are more interested in culture than in fashion shops; if you stay somewhere central, you can beat the traffic by walking everywhere. Christmas in Rome is a low-key family event. One of the nice things is the way the city keeps going. Although museums and shops are closed, many bars and restaurants stay open, and public transport continues to run. If you are lucky with the weather, it's in January and February that Rome is at its best. Late February can be especially attractive. One sometimes forgets what a difference that extra hour of daylight makes compared with mid-December. And there are always a few days of proper sunshine, when you can picnic in Villa Borghese and Pompeii. In which of the following periods would the writer most probably advise us to visit Rome?
Choices:
A. Late spring.
B. Mid-summer.
C. Early autumn.
D. Mid-winter. | D |

If your cellphone suddenly stops working, don't blame the service provider.The malfunction might well have been caused by something bigger -- a solar storm.Experts expect that Earth will see more solar activity in the near future.The malfunction of electronic devices will just one of the effects. Sunspots serve as an indicator of the sun's activity.For the past two years, sunspots have mostly been missing.Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise. When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This "solar minimum" doesn't last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum. What's special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now. Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina. What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level. However, there is also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether. What is the passage mainly about?
Choices:
A. The earth is in close contact with the sun.
B. Sunspots can cause trouble to our life.
C. Introduction of sunspots.
D. Introduction of the solar storm. | D |

I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task.It occurred at first that I did not recognize the handwriting,and then I realized whose it must be.I finally became aware of the fact that I had been working with this colleague for at least a year,maybe two,and yet I did not recognize her handwriting at that point. It was a very important event in the computerization of life--a sign that the informal.friendly communication of people working together in an office had changed from notes in pen to instant messages and emails.There was a time when our workdays were filled with little letters,and we recognized one another's handwriting the way we knew voices or faces. As a child visiting my father's office,I was pleased to recognize,in little notes on the desks of his staff,the same handwriting I would see at home in the notes he would leave on the fridge-- except that those notes were signed"dad"instead of"RFW". All this has been on my mind because of the talk aboutThe Rise and Fall of Handwriting,a book by Florey.She shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well,but many others argue that people in a digital age can't be expected to learn to hold a pen. I don't buy it. I don't want to see anyone cut off from the expressive,personal associations that a pen still promotes better than a digital keyboard does.For many a biographer,part of really getting to know their subjects is learning to read their handwriting. What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16th--century Italy.That may sound impossibly grand--as if they want kids to learn to draw by copying classical paintings.However,they have worked in many school systems. We can learn from the passage that the author _ .

A. thinks it impossible to teach handwriting

With more and more cars on the road, the traffic _ will happen. How do we see it and how can we solve the problem? We know that the traffic jam happens in many places, especially in big cities. What are reasons for the problem? On one hand, some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable. On the other hand, a growing number of people hope to use their cars to show off . What's more, years of research has shown that one of other reasons for the traffic jam is the driving habit. For example, many young people enjoy driving very fast, so they can feel excited. At last, most of them hardly care about the speed rules. Many governments are working at how to make the traffic better. In my opinion, firstly, the governments should educate those people who have cars or plan to buy cars. The governments must make them know that the traffic jam is very serious, and set up a much more perfect traffic system to solve the traffic pressure. Which of the following is NOT true?
Choices:
A. The reason for the traffic jam is that people have too much work.
B. The reason for the traffic jam is that more and more people drive cars.

From Sept. 1, Chinese children will be able to watch domestic cartoon programs during 5 p.m. every day, according to a regulation by prefix = st1 /China's TV watchdog. The State Administration of Radio, Film and Television (SARFT) has decided to ban all foreign cartoons during the "Golden hours", reported the Beijing News. No foreign cartoons or programs of introducing foreign cartoons can be shown during the period on all domestic cartoon channels, the regulation says. Only after 8 p.m. can foreign cartoons appear on TV, it requires. The regulation has been issued to local TV stations but the administration has not made it public, according to the newspaper. Cartoon programs co-produce by domestic and foreign producers will have to get approval from SARFT to show during 5 p.m. and 8 p.m. from Sept.1. The first foreign cartoon introduced to Chinawas a Japanese cartoon called "Astro Boy" series in 1981. Since then, a large quantity of foreign cartoons _ China. Incomplete surveys show about 80 percent of interviewed Chinese children like foreign cartoons according to the Southern Metropolis News. With the effects of regulations and establishment of 15 film and cartoon production bases in recent years, domestic cartoon industry attracted huge civil investment, resulting in a sharp rise of cartoon programs in 2005. However, due to the poor popularity among children, domestic cartoons found it hard to show during "golden hours", and even had troubles to get back the production costs. Moreover, it was the content of domestic cartoons that lost the audience, said the editorial, therefore improving the creation environment of cartoon makers is much wiser than such market-protecting measures. Finally it said it was reasonable and necessary to introduce system into the cartoon competition to protect the domestic industry, the complete prohibition of foreign cartoons and compulsory screening of domestic ones during popular hours was rather unreasonable. "This is a worrying, short-sighted policy and would not solve the fundamental problems in China's cartoon industry," it concluded. What attitude does the editorial in the Southern Metropolis News hold towards the ban?
Choices:
A. He thinks highly of the ban.
B. He raises a storm of objections to the ban.
C. He thinks Chinashould not improve the content of domestic cartoons rather than the ban.

Every small child knows the panic of losing sight of its mother in the supermarket, and as these delightful pictures show, small whales obviously feel the same way. Taken by a British diver who was following the sperm whale calf, _ show the minute the baby - who had lost track of its mum - found her again in the sea off the Azores. Soaring 30ft across the waves, the newborn slammed its body onto the water with joy after becoming separated from its family group in the chilly waters. But the whale calf was doing more than just jumping for joy. British biologist and dive guide Justin Hart, 44, who took the pictures, says that young whales communicate with older ones in the ocean by creating a slamming sound which travels through the water to the ears of the adults deep below. By leaping out of the water and slamming its 12ft long body onto the surface of the sea up to 30 times, the baby whale is telling its relatives where it is so they can regroup. He said: "We had been following the sperm whale calf for most of the day. Sperm whales, of all the whales and dolphins, are the species that dive the deepest and for the longest time." "The calves have to follow what's going on below them from the surface as best they can probably listening to the echo location clicks of the adults." "However, sometimes the adults re-surface far out of sight of the calf, and in this situation the whales often leap out of the water causing a large bang as their bodies hit the surface. In this way, the whale family could regroup." He added: "When I took the photo, two adults' females had just resurfaced and the calf quite literally began jumping for joy." Mr. Hart captured the rare image four miles from the port of Lajes do Pico while he was working as a crewman on an underwater documentary with special license to film sperm whales in the area. Sperm whales live in nearly all the world's oceans in groups of about 15 to 20 animals and they practice communal childcare. The calves do not have to follow their mother too closely as sperm whales can take milk from any milk-producing female in its social group. According to Justin Hart, the young sperm whale _ .

Malaria, the world's most widespread parasitic disease, kills as many as three million people every year--almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long. Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth--and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming. For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next. People suffering from malaria _ .

A smell may be attractive but it may not just be used for freshening air.One sports goods company once reposed that when it first introduced scent into its stores,customers'intension to purchase increased by 80 percent. When it comes to the best shopping streets in Pairs,scent is just as important to a brand's success as the quality of its window displays and goods on sales.That is mainly because shopping is a very different experience to what it used to be.

mmlu | Question:
When creating a digital advertisement or something to promote a product or service ,music is one of the most important aspects. Whether it is simply a jingle ,musical note or any other use of sound,music can play a huge role in attracting a customer's attention or being noticed by your target audience. Music can work hand-in-hand with what you are advertising. Many times the advertising jingle, or saying, is what the audience remembers. Companies such as McDonald's and Subway have used this method many times with different jingles and little sayings that are easy to remember and fun to sing along with. Usually concepts that are part of a jingle would sound conceited and pompous when said in a normal conversation. When put to music however, and sung in a rhythm,it suddenly sounds attractive. For example, if someone said," No one does it better than me" in a normal statement, this would sound very conceited. Add music and a tune to this statement and it becomes attractive and fun for others to sing along with. While understanding how important music is for your advertising needs, it is also important for you to know the best way to get special music. Having people from many different backgrounds all over the world write something specifically for you is one of the best ways to get songs written just for you. You simply choose which one you believe is best for the project. So instead of hiring a single songwriter to compose your music, you can run a contest for you advertising jingle and songwriters around the world write you a finished jingle in an attempt to win your contest.

Al Ossinger,an experienced mountain guide,knew it was time to leave Longs Peak in Colorado's Rocky Mountain National Park,and get off'quickly.The sky had turned threatening dark,and his ice ax at times gave out upset sounds.Suddenly,as Ossinger was crossing a large mass of rock,both hands pressed against it for balance,there was a roar,a flash of light and an electric current charged through his arms. "In that second. I thought 1 was finished,"he said,"Then I realized 1 was still there--the jolt hadn't knocked me off.My body and legs were all right,but my arms were paralyzed from the shoulder down.''Fortunately Ossinger was able to continue down and soon the feeling began to return to his shoulders,upper arms,and,two hours later,his fingertips.Ossinger was a lucky man. A single stroke of lightning,which is usually three to four miles long,travels at speeds of up to 100,000 miles per second.In a single flash,it can carry 100 million volts of electricity and reach a temperature of 55,000 degrees Fahrenheit,five times hotter than the surface of the sun.During its brief life span,lightning carries enough energy to power a 100-watt light bulb for as long as three months.If you find yourself unlucky enough to be near lightning's path,you could suffer a direct hit,sending electrical current though your body for some 5 00 milli-seconds.Because of the short duration,severe burns aren't common and the resulting burns are usually superficial . According to the national Weather Service,more people have been killed by lightning in the United States during the past 30 years,an average of 87 a year-than by either tornadoes or hurricanes,484 people were injured in 1994 alone.These"swords from the sky" are also responsible for an estimated$100 million to$300 million of property damage a year.During the 1980s an average of 5502 wildfires a year were sparked by lightning on national forest lands alone. Earth is struck by at 1east 100 of these flashes every second-more than 8.6 million strikes a day.For all its destructive power,lightning has its good sides too.It's likely that humans discovered fire from some early lightning-sparked flames.And all that activity above the earth may help create ozone ,which protects us from the sun's harmful rays.Lightning dancing across a summer night sky is a force to be respected and appreciated-from a distance. Electrical lightning is called"swords from the sky"to mean _ .

A. it looks 1ike swords
B. it can kill people

On a summer day, John was sitting on a beach in Hawaii with his parents. The six-year-old child suddenly said he was so lucky because he had so many toys to play with at home. His surprised parents replied that he was lucky, since a lot of kids didn't have any toys at all. "How can that be?" John said, confused, but then he said that he would like to get toys for those children. His parents naturally thought their son was just kidding. But as soon as they returned home, John began using his pocket money to buy toys for other kids and asking his friends to do the same. His parents responded by organizing pizza suppers for other families interested in helping other children that can't afford to buy toys. John thought that he just wanted to cheer those kids up. John's parents started to find a place that would allow children as young as six and seven to volunteer. They finally find a day care center for disabled children to let John and his friends visit. They went and played with these kids, playing around the room as if they belonged there. John and his friends named their work Kids Cheering Kids. John and his friends visited kids at some childcare centers, helping out with a party they organized. They also prepared a performance for children with disabilities. Their activities have drawn public concern. The spirit of helping is as fresh as it was that day in Hawaii. "The whole purpose," John says, "is to make the kids feel better."

mmlu | Question:
In our home it was natural to fear our father . Even our mother was afraid of him. As children, my sister and I thought every family was like that. Every family had an unpredictable dad who was impossible to please and a praying mom who was there to protect the children. We were good children. Mom was always telling us we were, even if Daddy couldn't see it . part of this was because we didn't dare to do anything. Then came the day we found something new and fun to do. We worked at drawing with chalk on our wooden front door and making lots of pretty pictures all over it. We had a great time. We thought Mom would love it and praise us. The praise we expected did not come. Instead, Mom was mad. We did not understand why, but we knew we were in big trouble! Off we ran to find a place to hid. In our wooded yard it was not hard for two small children to find safety. Together, we hid behind a tree and did not move. Soon we heard the frightened voices of Mom and our neighbors calling out to us. The sun set and it began to get dark. Those around us became more anxious, and we became more frightened. However, we still didn't move. As we clung together in the dark, we became aware of yet another voice, one we recognized with great fear: our daddy. But there was something strangely different about it. In it we heard something we had never heard before: fear, agony and despair. Then came his prayers in tearful voice. Our daddy was promising God that he would give his life to him if he would safely return his girls. Nothing in our lives had prepared us for this kind of shock. Neither of us remembers making a decision to come out. We were drawn to him like a magnet , our fears disappearing into the forest. We didn't know yet if we actually took steps or if God somehow moved us out and into Daddy's arms. What we do remember were those strong, loving arms holding us and crying, hugging us like we were precious. Things were different after that. _ . Our whole family was changed by a piece of chalk.

American football is different. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field. They have four chances to move the ball ten yards . They can carry it or they can throw it. If they move the ball ten yards, they can try to move it another ten yards. If they move it to the end of the field, they receive six points. It is difficult to move the ball. Eleven men on the other team try to stop the man with the ball.

Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths due to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors beat that among female by nearly 10 percent . The statistic is reversing . Third, several recent studies have indicate high school _ have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking level among youth. Every day there are over _ high school students who will become regular smoker.

mmlu | Question:
What do working mothers worry about the most? It's the kids of course. Whatever the setting, the question I get asked the most is "Will the kids be alright?" It has made me realize that we tend to look at the glass half-empty rather than half-filled when it comes to mixing work and family. We forget about all the benefits that we bring to our children when we work - and I'm not talking about the obvious financial benefits, although these of course shouldn't be taken for granted. About a year ago I remember getting a call from the school just as I was pulling up to the house after having driven 20 minutes to the school and 20 minutes back. "Mrs. Brown Quinn, your son asked us to call. He forgot his sports clothes. Can you come back to the school and drop them off?" I was exasperated ! I had already spent 40 minutes in aggressive weekday morning traffic. I replied, "Sorry, I'm working at the moment. I'm afraid my son needs to learn to be organized." Being a good parent requires delivering tough love sometimes. Kids need to learn to be independent. It can be a cruel and competitive world out there. Seeking interests, including business, outside of your kids, can give you that extra idea that you need not care for your kids with attention. This benefit of working isn't always immediately evident. It wasn't until our daughter went away to college that she realized why we had raised her in the way that we did. "Mom, I can't believe how so many of my friends struggle to manage things on their own. They are constantly calling their parents for help." You'll love that moment! After all those years of complaining about why you don't do this or why you don't give them that, your kids realize that tough love has made them better people. The daughter's attitude towards the author is _ when she grows up.

mmlu | Question:
It's hard to avoid looking like a fool on April Fool's Day. On April 1 each year, people play tricks on each other. These tricks are usually silly rather than mean. Classmates sometimes tie each other's shoelaces to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke. Newspapers announce fake contests (such as "Win an elephant!") and report on fake stories (like "UFO" lands in New York City). Forget gifts, songs and special foods--those are for the other holidays of the year. On April Fool's Day, the only tradition is to laugh (and maybe to cause a little bit of trouble). One April Fool's Day, when I was in high school, a group of students in my class played a very clever and funny trick on the teachers. They bought some chickens and set them free in our school cafeteria. The chickens ran all round the school, in and out of classrooms and under our feet. Feathers were flying everywhere. Teachers began running after the chickens, trying to catch them. Finally, they caught four of them. But the chickens were wearing numbered tags around their necks, and the teachers discovered that they had only caught chickens No.1, 2, 3, and 5.Where was chicken No.4? The teachers looked and looked. They couldn't find another chicken. After a few hours, they realized that the students had played another joke on them: There were only four chickens in the first place! They've been tricked by the numbers on the chickens. It's been a long time since I was in high school, but that April Fool's Day remains one of my favorite memories from those years. How many jokes did the students play on teachers?

Impossible cases are not forever. While it is impossible for one person, it is possible for another. In a word, everything is possible. Someone says, "Success belongs to those who can look at the complex challenges offered by the world as inspiration." So your challenges are golden opportunities for success. How can there be miracles if there are no obstacles? How will you chase the storm if there is no storm? You need challenges to reveal your ability. Success doesn't come out' of nothing; success comes from the problems you face. Those who refuse to give in come out smiling. Robert X. Perez says, "The seeds of success spring from failure's ashes. "Failure is not defeat; it is the pointer to do better than what you just did. You have to know that you are in a constant study of life. What you face is for your training. Samuel Aidoo says, "Each failure is simply another chapter in the story of our lives. To fail is to understand what not to do. Remember it and don't give up until your goal is achieved." What do you do when you face difficulty? Yeah, life is difficult, but you do not give up. Have a positive and calm outlook on your circumstances and make the best of them. You may learn something new. You can develop mental toughness. Mental toughness means to be able to see the long-term gains rather than be put off by short-term pains. Once you have this toughness, you have the winning edge . The only things in life you ever really regret are the chances you didn't take. You will regret when you see the consequences of not seizing the opportunities when they arose. Take chances every day! The main point of the passage is that _ .

A. success comes out of nothing
B. never give up and you may achieve success

The government employs many people to help take care of our society. However, these professionals cannot help out everyone just by themselves. They need our help! Consider Volunteering! What Exactly is Volunteering? Volunteering is when we regularly go and do nice things for other people. Volunteers may help out in local retirement homes, or in hospitals. Some volunteers work with poor people and other volunteers help teach orphaned children to read. There are many types of volunteers who help those who need help the most. Volunteering Teaches Mature Thinking Volunteering is something that really helps us as individuals. It gives us a chance to stop complaining about our own lives, and realized exactly how lucky we are. We are able to see the people who really need help. Volunteering also teaches us more about responsibility, patience, empathy , and above all, compassion . Doing Our part! Volunteering gives us a chance to do our share of the work of making this society the best it possibly can be. It helps us feel good about ourselves when we can help those who really need our help. When we can make someone else feel special, it helps us remember what life is really about. Ways to Start Volunteering There are many places that you can go to try to start volunteering. Here are just a few places you can go and what you can do at each place. 1) Hospital-ask if you can go and visit people who are really sick. Sometimes all they need is just someone who will talk with, or someone to give them hope. 2) Orphanage-the children living here really need someone to play with them. 3) Food Shelter --many food shelters can really use more people willing to just organize the shelters and help distribute the food to those who need it. Whatever you decide to do, just do the best you can. Remember that giving can be its own reward! Volunteers mainly help all of the following people EXCEPT _ according to the passage.
Choices:
A. patients in hospital
B. children without parents

So you're beween the ages of 13 and 24.What makes you happy? A worried,weary parent might imagine the answer to sound something like this:sex,drugs,a little rock 'n' roll .Maybe some cash,or at least the car keys. It turns out the real answer is quite different Spending time with family is the top answer to that open-ended question,according to an extensive sur-vey--more than 100 questions asked of 1,280 people aged 13-24--conducted by The Associated Press and MTV on the nature of happiness among America's young people. Next is spending time with friends,follwed by time with a significant other.And even better for parents:Nearly three quarters of young people say their relationship with their parents makes them happy. "They're my foundation,"says Kristiana St.John,17,a high-school stu-dent from Queens in New York."My mom tells me that even if I do something stupid,she's still going to love me no matter what.Just knowing that makes me feel very happy and blessed." You might thik money would be cleauly tied to a general sense of happi-ness.But almost no one says"money" when asked what makes them happy,though people with the highest family incomes are generally happier with life.However,having highly educated parents is a stronger predictor of happiness than income. From the body to the soul:Close to half say religion and spirituality are very important.And more than half say they believe there is a higher power that has an influence over things that make them happy.Beyond religion religion,simply belonging to an organized relious group makes people happier. And parents,here's some more for you:Most young people in school say it makes them happy.Overwhelingly ,young people think mar-riage would make them happy and want to be married some day,Most also want to have kids.

Once in a blue moon, there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue - the name has nothing to do with the color of our closest celestial neighbor. A full moon occurred on December 2. It will appear again on Thursday in time for the New Year's countdown. The New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up until New Year's Day, making January a blue moon month for them. A full moon occurs every 29.5 days, and most years have 12. On average, an extra full moon in a month - a blue moon - occurs every 2.5 years. The last time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't come again until 2028. "Blue moons have no astronomical significance," said Greg Laughlin, an astronomer at the University of California. "`Blue moon' is just a name in the same sense as a `hunter's moon'(a full moon in octorber) or a `harvest moon,'" Laughlin said in an e-mail. The popular definition of blue moon came about after a writer for Sky & Telescope magazine in 1946 misinterpreted the Maine Farmer's Almanac and labeled a blue moon as the second full moon in a month. In fact, the almanac defined a blue moon as the third full moon in a season with four full moons. Compared with the hunters moon, the blue moon _ .

On March 1, Computer Programs, Inc. (CP) orally agreed with Holiday Department Store (HDS) to write a set of programs for HDS's computer and to coordinate the programs with HDS's billing methods. A subsequent memo, signed by both parties, provided in its entirety: HDS will pay CP $20,000 in two equal installments within one month of completion if CP is successful in shortening by one-half the 17 processing time for the financial transactions now handled on HDS's Zenon 747 computer; CP to complete by July 1. This agreement may be amended only by a signed writing. On June 6, CP demanded $10,000, saying the job was one-half done. After HDS denied liability, the parties orally agreed that HDS should deposit $20,000 in escrow, pending completion to the satisfaction of HDS's computer systems manager. The escrow deposit was thereupon made. On July 5, CP completed the programs, having used an amount of time in which it could have earned $18,000 had it devoted that time to other jobs. Tests by CP and HDS's computer systems manager then showed that the computer programs, not being perfectly coordinated with HDS's billing methods, cut processing time by only 47 percent. They would, however, save HDS $12,000 a year. Further, if HDS would spend $5,000 to change its invoice preparation methods, as recommended by CP, the programs would cut processing time by a total of 58 percent, saving HDS another $8,000 a year. HDS's computer systems manager refused in good faith to certify satisfactory completion. HDS asked the escrow agent to return the $20,000 and asserted that nothing was owed to CP even though HDS continued to use the programs"Assume for this question only that the programs completed on July 5 had cut processing time by one-half for all of HDS's financial transactions. Is HDS entitled to renounce the contract because of CP's delay in completion?
Choices:
A. Yes, because "CP to complete by July 1" is an express condition.
B. Yes, because the doctrine of substantial performance does not apply to commercial contracts.
C. No, because both parties manifested an understanding that time was not of the essence.
D. No, because the contract did not contain a liquidated damages clause dealing with delay in completion | C |

A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said, "I am blind, please help." There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words. Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy heard his footsteps and asked, "Were you the one who changed my sign this morning? What did you write?" The man said, "I only wrote the truth. I said what you said but in a different way." What he had written was, " Today is a beautiful day but I cannot see it." Do you think the first sign and the second sign were saying the same thing? Of course, both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind. The first sign simply said the boy was blind.

How clean are the nation's homes? According to a survey by CIF, there's room for improvement all over Britain. Love or hate it -- cleaning your home is one job you simply can't ignore . But that's not to say everyone spends the same amount of time or effort on making their places spotless. A new survey by CIF-- experts on making tough cleaning jobs easier---- shows that when it comes to washing windows or cleaning the oven ,where you live in the UK it may show how much effort you put into the task. BATHROOM 25% of men have never cleaned the toilet -- but those in Wales are the worst. Nearly four in 10 Welsh men said they never cleaned anywhere in the house. Hate cleaning the shower head? You're not alone -- a quarter of a million Brits say the same. 20% of Scots regard window-cleaning as their most hated job. KITCHEN 36% of people in the south-east say cleaning the cooker is their hated task. 68% of those in the north-east spend more than six hours a week cleaning their homes -- especially the kitchen -- in sharp contrast to the 49% of Welsh and West Country folk, who put their hands up to cleaning for under an hour. BEDROOM 18% believe cleaning starts here: that's the percentage of women who clean wearing their dressing gowns. 51% of women in the north-west may be staying in bed and giving their husband a cuddle --as a thank-you for helping them clean.

A report by the Consumer Electronics Association says electronics are among the most popular gifts being bought this holiday season. Jim Barry is a spokesman for the Consumer Electronics Association. He says the CEA study found that electronics represent three of the top five things on its "holiday gift wish list" this year. JIM BARRY: "Notebook computers are at the top, followed by iPads and then e-readers. IPad is a touch-screen tablet computer and that's really the big player in that category." The computer company Apple began selling its small, touch-screen computers in April. People use the touch-screen computers to surf the Web, write e-mails, watch movies and read books. Since the iPad's release earlier this year, several other companies have come out with their own tablet computers just in time for Christmas. A report from the e-Marketer research group predicts that worldwide, tablet sales will reach more than eighty-one million in two thousand twelve. Still, Jim Barry says these devices are facing tough competition this year from another Christmas favorite. JIM BARRY: "Another hot category right behind that are the e-readers. So you can read on an iPad or a touch-screen tablet, but the e-book readers are less expensive. The Kindle is the market leader there, from Amazon. But you also have the Nook from Barnes and Noble and the e-reader from Sony. And you have more and more of those e-readers coming into the market as well." The Consumer Electronics Association report found that iPod music players are also in high demand this holiday season. But not all of the things on the holiday gift wish list involved electronics. Clothes, cars and motorcycles also made the list. So did family togetherness and good health. And the one thing that people wanted most? JIM BARRY: "At the top of the list was peace and happiness." That is also our wish for you this holiday season. People use the touch-screen computers to do all the following things except _ .

Meet Jeff Wilson AKA Professor Dumpster , an environmental scientist and the Dean of Huston Tillotson University in Austin, Texas. The reason for his unusual nickname? He has decided to live in a dumpster for the next year. Yes, the kind that you might find filled with trash behind a restaurant. Wilson says the inspiration to do something first hit him two years ago, when he was working on an article at a neighborhood coffee shop and caught sight of an eight-yard dumpster. Now that he has found one, Professor Dumpster is putting his students to work. After all, the point of this project isn't just to spend his life living out of a garbage can: there is, a much greater purpose involved. As an environmental scientist, the professor constantly thinks about sustainable living and how every person should try to minimize his/her impact on our already stretched resources. That, is the challenge Wilson wanted his students to step up to, this entire year. Using their math, science, engineering and technology skills, he wants them to retrofit his 33 square-foot dumpster into a modern space that includes a shower, a toilet, a kitchen and a bed and is fitted with conveniences like air-conditioning and even WiFi. The demand? It all has to be green and sustainable. www.ks5u.com So why is Wilson planning to go through such hardship? That is because he wants to equip his students with the tools to survive in a world that is rapidly heading towards a population of 10 billion people. A large majority of the population adjust to living in tighter spaces in the world where resources and space should be limited to be used. By promoting awareness and education on these subjects, Wilson is helping students everywhere see that living "small" and sustainably is certainly possible. And while the dumpster project may seem a little crazy to some, the professor thinks of it as a "playful and imaginative" educational experiment and conversation-starter to discuss the fact that all of us can do with less as we move into the future. What is the best title for the passage?
Choices:
A. How Should We Teach Our Students in Effective Ways?
B. Who Will Be the Next One to Live in a Dumpster?
C. Why Is This Professor Moving into a Dumpster?

mmlu | Question:
Six years ago, a Miami woman walking through the hall of an office building casually noticed two men standing together. Several minutes after her leaving, the men murdered a person working in the building. Police investigators determined that the woman was the only witness who had seen the two suspects, and could possibly describe them. In an interview with police, her memory of the men proved disappointingly unclear. Several days later, psychologist Ronald P. Fisher was brought in to get a more complete description from the woman. Fisher's interview produced a breakthrough--the woman reported a clear picture of one of the suspects. She then recalled several details about his appearances. This information gave police important leads that enabled them to arrest the suspects and close the case. Police investigators found the help from Fisher because of his rich knowledge in conducting the so-called cognitive interview, a kind of memory-rebuilding process. In its original form, the cognitive interview focuses on guiding witnesses through four general recalling techniques: thinking about physical surroundings and personal feelings that existed at the time of past events, reporting everything that comes to mind about those events no matter how broken or unconnected, retelling events in kinds of time orders, beginning to end, end to beginning, forward or backward, and accepting different views while recalling events. Usually, an interviewer begins the cognitive approach by encouraging the witness to take an active role in recalling information rather than giving answers only to someone else's questions. The witness first describes what happened in his or her own words, with no interviewer interruptions. The interviewer then goes further with specific techniques, such as having the witness tell the details of what happened from different aspects. Experiments with police detectives trained in this demanding interview method find that they get nearly 50% more information from witnesses than before training, while error rates remain about the same. It can be inferred from the passage that in a cognitive interview, the interviewer mainly plays a _ role.
Choices:
A. directing
B. questioning
C. disappointing
D. interrupting | A |
mmlu | Question:
In recent years, temperatures in the polar areas are rising faster than anywhere else on Earth. As a result, the ice and the snow are melting at record-setting rates. One result is that sea levels are rising around the world, putting animals and people at risk. A sheet of ice acts like a huge mirror, reflecting the sun's energy. But ocean water, which is darker than ice, absorbs a lot of it. This causes the ocean to warm, which in turn speeds up ice melting and which leads to even more open waters. The cycle continues until all the ice is gone. "As the ice melts, water flows into the oceans, making them less salty. That, along with warmer water temperatures, can harm the creatures that live in, under, and near the ice," says zoologist Michael Stoddard. "Cold-adapted animals -- including polar bears, foxes, hares, and seals -- also need ice for travel and survival." "Most species of fish, sea spiders, and many other animals and plants that live in the waters of Antarctica don't live anywhere else," Stoddard says. "Many of them have special proteins in their bodies keeping them from freezing to death and have other adaptation to the cold that has yet to be explored." Therefore, experts are urging us to reconsider the way we live. The fuels that we burn in cars, power stations, and factories are largely to blame for the carbon dioxide and other greenhouse gases that are trapping overmuch heat in our atmosphere. If we can produce fewer of these gases, we can help save the polar ice. "Even small things would make a difference, if everyone did them." Michael Stoddard says, "That's what we have to figure out in the near future to help save the polar ice and thus protect the oceans and us." The passage is mainly written to _ .
Choices:
A. introduce the present situation of the polar areas
B. warn people against extreme weather
C. call on people to protect the oceans and humans
D. advertise for volunteers to protect the environment | C |
