mmlu | Question:
Once I invited a group of friends round to my house, telling them that I was going to record their speech. I said I was interested in their regional accents, and that it would take only a few minutes. Thus, on one evening, three people turned up at my house and were shown into my front room. When they saw the room they were a bit alarmed, for it was laid out as a studio. In front of each easy chair there was a microphone at head height, with wires leading to a tape-recorder in the middle of the floor. I explained that all I wanted was for them to count from one to twenty. Then we could relax and have a drink. I turned on the tape-recorder and each in turn seriously counted from one to twenty in their best accent. When it was over, I turned the tape-recorder off and brought round the drinks, and for the rest of the evening there was general cheerful conversation--interrupted only by the fact that I had to take a telephone call in another room, which unfortunately lasted some time. Or at least that was how it would appear. For, of course, the microphones were not connected to the tape-recorder in the middle of the room at all but to another one, which was turning happily away in the kitchen. The participants, having seen the visible tape-recorder turned off, paid no more attention to the microphones which stayed in front of their chairs, only a few inches from their mouths, thus giving excellent sound quality. And my lengthy absence meant that I was able to obtain as natural a piece of conversation as it would be possible to find. I should add, perhaps, that I did tell my friends what had happened to them, after the event was over, and gave them the choice of destroying the tape. None of them wanted to--though for some years afterwards it always seemed to be my round when it came to the buying of drinks. Linguistic research can be a very expensive business. Which one is true according to the passage?
Choices:
A. The writer destroyed the tape.
B. The writer's friends destroyed the tape.
C. The writer did tell his friends what had happened.
D. The writer's friends like to drink. | C |

mmlu | Question:
Of all the components of a good night's sleep, dreams seem to be last within our control. In dreams, a window opens into a world where there is zero logic and dead people can speak. A century ago, Freud formulated his revolutionary theory that dreams were the hidden shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just "mental noise"--the random byproducts of the neural repair work that goes on during sleep. Now researchers suspect that dreams are regulating moods while the brain is "offline". And one leading authority says that these intensely powerful mental events actually can be bought under conscious control, to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychology at Chicago's Medical Center. "If you don't like it, change it." Evidence from brain imaging supports this view. The brain is as active during rapid eye movement sleep when most vivid dreams occur as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved: the limbic system or the emotional brain is especially active, while the prefrontal cortex--the center of intellect and reasoning, is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day," says Stanford sleep researcher Dr. William Dement. This link is shown among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events--until, it appears, we begin to dream. There is probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "We wake up in a panic," Cartwright says. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep or rather dream on it and you'll feel better in the morning. Casual nightmare sufferers are advised to _ .
Choices:
A. ask for medical help
B. relax their mind during the day
C. don't take the dreams seriously
D. realize the emotional significance of daily events | C |

mmlu | Question:
A few years ago, my younger sister and I were the first to board our flight for Norfolk, Virginia. Just as we were about to board the plane, a mechanic came out of the aircraft and blocked the door with his arms. He turned to the flight attendant and hurriedly stated, "We got problems!" I thought to myself, "Why did I have to be the one to hear that? Why couldn't I have been at the back of the line? I didn't need to know that!" Very soon we were back in the terminal, waiting, and then finally back on the plane. I waited for the pilot to give an explanation. Pilots take courses to ease passengers' mind, right? They know what to say to calm nerves. Unfortunately, I didn't think this pilot took that course. Soon his voice thundered throughout the plane, "Sorry for the delay, ladies and gentlemen. We had no power on the plane. We have a generator on the ground right now, and we're going to jump-start the engines. Once we get them going, we'll get up in the air and head to Norfolk, and see what happens." See what happens? We were going to get up in the air, and see what happens? Couldn't we have another plan, one that's been worked out just a little better? At this point, all I could do was to laugh nervously. One woman started yelling, "Oh no! We're going to crash!" There were sighs of desperation and anxiety spreading throughout the cabin. Finally, we got up in the air thirty minutes later, and what happened? Nothing ---other than thrust and lift. We arrived in Norfolk, and no sooner had the wheels touched the ground than a round of applause burst out, as everyone throughout the airplane simultaneously breathed a sigh of relief. Although, I did sincerely like to have a plan better than "see what happens" worked out when flying --- it really isn't such a bad life strategy. Success will never be guaranteed. The best thing you can do is just get up in the air, and see what happens. Sometimes adjustments would be made in the air, or shall we say, in the middle of the process. The purpose of the text is to _ .
Choices:
A. introduce a frightening flight experience
B. prove that taking a plane is dangerous
C. show a strategy of making plans
D. tell readers a life strategy | D |
mmlu | Question:
If you are really interested in music festivals, then you have probably heard of the Bestival Music Festival. It takes place every September on the Isle of Wight, the UK. As it is at the end of summer, people think it's their last chance to go to a festival and have fun before going back to boring work. The dream begins as soon as you start traveling to the island. In order to get to the campsite of the Bestival, you have to take the ferry . The ferry is full of happy festival lovers who are ready to take part in the fantastic music party. After you arrive at the campsite, you can put your tent up. There people talk with each other openly. They are not that cold like those you meet in your everyday life. The festival lasts for four days. During that time you forget all your worries and problems, just like living in a dream. And it is really hard for you to come back to "reality" after that. It seems that it is this kind of music event that makes people gather together. It gives people a real sense of unity. I took part in the Bestival with my friends the year before last. It was so exciting and we all lost ourselves in the beautiful music. We are family sung by Sister Sledge was my favorite. I'm really looking forward to joining in it for a second time.

mmlu | Question:
There once was a boy named Kevin. He met Jessica one afternoon at a park on a hot summer day. They both started talking and became great friends. They spent the whole day together and ate their lunches together next to the pond. Kevin sure enjoyed the park more than he liked going to the beach or store. There were many ducks, frogs, birds and chipmunks playing around the pond. In fact, one of the chipmunks even came up and stole Kevin's car keys when he was eating! Kevin knew that he needed to go have his keys, but the chipmunk ran with an evil smile on its face. Eventually, the chipmunk ran into its hole that he called home. Kevin tried everything he could to have the chipmunk come out with his keys, but he couldn't find out how to make the little guy give up. Finally, Jessica came over and placed a potato chip at the opening to the hole. In seconds, the chipmunk came out with the keys and dropped them in front of Kevin right before grabbing the chip and running back into the hole. The chipmunk then went in to have his snack and left Kevin and Jessica alone. Kevin thought that maybe next time he could go to the park in the early spring or winter so that the chipmunks would be busy sleeping during the cold weather months.

mmlu | Question:
Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water. In time, however, they broke _ and went back to where the necessary vitamins were. In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet. So, in selecting food, rats and babies do seem to know and act on what's best for them. Apparently, there is a kind of "body wisdom", which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-established habits. Some people eat fox, dog and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them. According to the passage ,adults eating habits differ from those of babies because _ .
Choices:
A. adults know better than babies what kind of food are good for their health
B. adults usually cannot resist the temptation of various delicious foods
C. adults' eating habits are closely related to the social and cultural customs
D. adults have more choices of food than babies in eating patterns | C |

mmlu | Question:
Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science. Scientists have changed the colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes . The number, size and darkness of melanosomes per pigment cell determines skin colour. It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation in the gene for melanosome production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra fish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colours, said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment done on Michael Jackson. Which of the following is NOT mentioned according to the passage?
Choices:
A. The version of the pigment gene of Asians and that of Africans are the same.
B. Scientists have succeeded in turning the colour of a dark-striped zebra fish into uniform gold.
C. Dark skin can protect bodies from utral-violet rays of the sun.
D. People like pop king Michael Jackson. | D |

mmlu | Question:
Even plants can run a fever, especially when they're under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away--straight up. A decade ago, adopting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and longterm backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago. Plants will send out an increased amount of heat when they are _ .
Choices:
A. facing an infrared scanner
B. sprayed with pesticides
C. in poor physical condition
D. exposed to excessive sun rays | C |
mmlu | Question:
The sea is very big. When you look at the map of the world, you will find there is more water than land. The sea covers three quarters of the world. It looks very pretty when the sun is shining on it. It can be very rough when there is a big wind. The sea is also very deep in some places. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan, where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place, there would be 2 kilometers of water above it! The sea is salty. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are more salty than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers can't sink! Fish can't live in the Dead Sea! The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to a depth of eleven kilometers. Why can't people go very deep into the sea?
Choices:
A. Because of the coldness of the water.
B. Because of the living things in the sea.
C. Because of the pressure of the water.
D. Because of the salt in the sea. | C |

mmlu | Question:
Qi Haoran, a Junior 1 student at High School Attached to Harbin Institute of Technology, was quite busy over the past winter vacation--and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign . The 11 students went to many restaurants and told people the importance of saving food."Excuse me, do you know that 950 million people around the world still haven't got enough to eat? Could you please not waste food?"They would say this kind of thing hundreds of times every day. China in recent years has experienced serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. It's a tradition that Chinese people offer lots of food when they invite others to dinner. Many even feel that they will lose face if their guests have eaten all their food. Luckily the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives the guests who have eaten up all that they ordered a sticker. People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers home. Wasting food is a serious problem around the world, not only in China. It's said that 2 billion tons of food ends up as waste every year in our country. This is as much as half of all the food in the world. The UN Environment Program and the Food and Agriculture Organization held a"Think, Eat, Save" program on January 24 to help reduce food waste. To reduce food waste is a big task, and it needs time. It's important that everyone does their bit, just like Qi. Did you finish your meals today? What did the restaurant in Xinjiang do to support the campaign?
Choices:
A. The owner would have dinner with those who had eaten up their food.
B. It offered a free meal to the guests who had finished all their food ten times.
C. It gave stickers to the guests who ordered small dishes.
D. It encouraged customers to take leftovers home. | B |

mmlu | Question:
In bringing up children, every parent watches eagerly the child's acquisition of each new skill -- the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality . Also, parents should realize that "example is better than _ ". If they are not sincere and do not practice what they preach , their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment. In terms of moral matters, parents should _ .
Choices:
A. follow the rules themselves
B. be aware of the huge difference between adults and children
C. forbid things which have no foundation in morality
D. always ensure the security of their children | A |

mmlu | Question:
Ancient humans were afraid of the sight of comets . Many cultures believed that comets were messages sent by gods, and people thought these messages were warning signs for bad behavior. But today science and technology give us a better understanding of comets. Last week, comet Ison ended its million-year-long journey as it flew straight toward the sun, melting most of the comet. It was hoped that comet Ison would survive this trip around the sun. Because once it got near Earth, it would have produced a great show of lights for us. In ancient times, the coming of comet Ison might have scared people. However, now we can track a comet's journey in our solar system. We can also study what they're made of. There is even a project to launch a spacecraft onto a comet to study them further. Although from the sky they look like great giant fireballs, comets are a collection of gas, ice, dust and small rocks. As a comet goes into our solar system, the sun's solar winds blow some of the dust and gas away, giving the comet a tail. The average size of comets is about 10 kilometers in diameter . But amazingly, their tails can be 150 kilometers long! Comet Ison's diameter was about 5 kilometers. Today, people don't fear comets as much as they did before. Western countries have even developed and old tradition. When people see a comet or meteoroid shooting across the sky, they call it a shooting star, People who get the chance to see one get to make a wish. It is a tradition that lives on today. In ancient times, people thought comets were _ .

A. warning signs sent by gods
B. lucky signs for good behavior
C. great shows of lights

Scientists added a record of 715 more planets to the list known to the world beyond the solar system, astronomers said on Wednesday, in February 2014. The additions include four planets about 0.5-2 times as big as Earth that are the right distance from their parent stars for liquid surface water, which is believed to be fit for life. The discoveries were made with the NASA's planet-hunting Kepler space telescope. The telescope, launched in 2009, spent four productive years observing 160,000 target stars for signs of planets passing by, within the telescope's sight. The numbers of planets announced at a NASA press conference on Wednesday increased Kepler's confirmed planets from 246 to 961. Combined with other telescopes' results, the total number of planets beyond the solar system now is nearly 1,700. "We almost doubled, just today, the number of planets known to humans," astronomer Douglas Hudgins, head of planet exploration at NASA Headquarters in Washington, told reporters on a conference call. Many planets' discovery is due to a new technique that analyzes potential planets in _ rather than one at a time. The method was developed after scientists realized that most planets, like those in the solar system, have similar worlds orbiting a common parent star. The newly found planets strengthen the evidence that small planets, two to three times the size of Earth, are common throughout the galaxy . "Generally, wherever (Kepler) can see them, it finds them," said astronomer Sara Seager, with the Massachusetts Institute of Technology. "That's why we have confidence that there will be planets like Earth in outer space." Like the solar system, which has eight planets plus Pluto and other so-called "dwarf planets," the newly found planets belong to families. But unlike the solar system's planets, which are about 150 times farther from the sun than Earth. Most of the planets fly nearer to their parent stars than Venus orbits the sun, a distance of about 67 million miles (108 million km.) NASA and other space agencies are designing new telescopes to discover planets in so-called "habitable zones" around their parent stars where temperatures would be suitable for liquid surface water. Two papers on the new Kepler research will appear in an upcoming issue of 'The Astrophysical Journal'. Which of the following is the most suitable title for this passage?

A team led by Professor Theoder Berger, from the University of Southern California, can now manipulate brain cells in rats so that memories stored in the hippocampus, a brain area crucial for memory formation, are activated or suppressed . It's said that _ could one day have medical applications. In the study, researcher first trained rats to remember which of two levers they pressed first, then to press the other lever. As the rats performed the task, the scientists carefully monitored the electrical activity in each creature's hippocampus to find the pattern of nerve-cell activity involved in making a solid memory. Using the same glass needles they had used to record the nerve activity, they stimulated nerves in the same pattern and found that the animals' performance in the task got even better. The rats made fewer errors and were able to remember which lever was the"correct"one for a longer period of time. The scientists went a step further and suppressed the rats' memories with a drug called Mk801, which caused them to forget their task. When the animals' brain cells were later stimulated with the"correct"pattern, they remembered again which lever to press. "What's really exciting about this study is that when they played back the'good' patterns--the patterns when the animal got the task right--it did appear to improve memory,"said Dean Buonomano, an associate professor at the University of California. The final goal, Berger said, is to help people with stroke and epilepsy and the like strengthen memories and to help doctors treat them. The technology might even help sufferers of post-traumatic stress disorder. But first, researchers would have to show that they can stimulate or suppress far more complex memories than the ones in the rat experiment. "Here ,it's a simple task,"Buonomano said. In contrast, humans' memories are very rich and specific... "We have very many steps to go before this can be achieved,"he said. What can we infer from the article?
Choices:
A. MK801 is a drug that can be used to stimulate nerves.
B. The study is expected to be used to help stroke and epilepsy patients recover completely.
C. Using the study to improve humans' memories still face many challenges.
D. Researchers have studied far more complex memories than the ones in the rat experiment. | C |

Looking up at the ceiling, Na He Jeon pours porridge into her mouth. She carefully dips the bowl forward, dropping the porridge directly down her throat, careful not to touch the 15 ulcers in her mouth. But it was the week before midterms, so she still had to study. Jeon was 1st out of 330 students on her exams that year. "Thank god I did," she says. "If I hadn't done well I would have been regarded as a failure." By the end of the week, 14-year-old Jeon weighed only 83.6 pounds. Like Jeon, there are countless numbers of first generation Asian-Americans who make great efforts to go beyond at everything. Yet the children themselves cannot all be put to blame for their efforts. Typically, it is the parents who are designing a life which they see as perfect for their children. One such occurrence is when I was at my hotel in Beijing. It was roughly around 8:00 p.m. when I decided to take a dip in the pool after dinner. I jumped into the pool that was already spotted with a few Chinese children and I hadn't realized what was going on until I took notice of the parents calling out orders and instructing their children. I saw various children all under the age of 10 taking laps across the pool trying various styles. If a child's foot was too bent, her parent would demand that she straighten it. If a child was kicking too slowly, his parent would order that he go faster. I couldn't help but pity the children whose parents were taking the opportunity to give a swimming lesson, rather than just let them enjoy their time during the holiday. Either because of their parents or their own desire, first-generation Asian-Americans put forth their 110% in order to be accepted into one of the best American colleges. Asian-American students want to see A's, 100%'s, and perfect scores. According to Jeon, Asians complain that students with a 4.0 GPA and 2400 SAT simply cannot be rejected from top schools. To their disappointment, however, they often are. The ethic of this aggressive work also exhibits itself via sports and other after-class activities. What sets Asian-Americans apart, however, is that they fight to be excellent in whatever it is that they do. Be it playing the piano or performing in math competitions, Asian-Americans look to be in first place. Although it may cause unnecessary stress, such a driven work ethic is a _ quality. Often blamed for lacking in creativity, Asian-Americans can actually make up for the absence of imagination with their determination. The average American can dream creative dreams, but that only matters if he or she can make it happen in reality. Asian-Americans, instead, can gather creative ideas to produce something concrete. Yet with such a drive to succeed, Asian-Americans have somehow twisted their definition of success. Rather than looking at personal achievement, they refer to numbers, statistics and scores to rate their success. It seems as if desire and the sense of free will are nonexistent in certain Asian-American students as they mercilessly drive themselves to an inevitable burnout. Their desire to be the most-talented is an impossible dream. In a fruitless attempt, they try to be the best in a world already full of winners. The writer's purpose of writing this article is to _ .
Choices:
A. express sympathy for Asian-American children
B. advocate academic competition among students
C. stress that personal success means more than high scores
D. analyze the problems in school education | C |

Spring is a wonderful season to celebrate rebirth and new life. The long, cold winter is over. The weather is warmer and sunnier. The trees again have leaves and the flowers are blooming. The season represents hope, joy and beauty. At this time, many people think of this classical music piece -- Spring, which shows happiness. Italian composer Antonio Vivaldi wrote it in the seventeen hundred. However, not all songs about spring are happy. This song written and sung by K.D. Lang is about dreaming of spring in cold dark places. She recorded I Dream of Spring in 2008. Richard Rodgers and Oscar Hammerstein wrote It Might as Well Be Spring for the movie State Fair in 1945. Frank Sinatra sings it. It is a feeling of restlessness or excitement brought on by the coming of spring. Richard Rodgers also wrote Spring Is Here, this time with Lorenz Hart. Ella Fitzgerald sings this song about feeling lonely during this season. Frank Loesser wrote the sad song, Spring Will be a Little Late This Year. Why has the season been delayed? Because the singer's lover has left her. Sarah Vaughn released her version of the song in 1953. By now you may be thinking, "Enough with the sad songs, already!" Ok, then how about a cowboy song? Gene Autry was one of America's most famous singing cowboys. He recorded When It's Springtime in the Rockies in 1937. And finally, we'll leave you with a sunny song called Up Jumped Spring.

Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood. When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage. We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the tree and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird. I decided that I would catch a young bird and keep it in a cage and that way have my own private musician. I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home, I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician. I had left the cage out on our back porch , and on the second day of the bird's captivity my new pet's mother flew to the cage with food in her mouth . The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby. The following morning when I went to see how my captive was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened? I had taken excellent care of my little bird, or so I thought. Arthur Wayne, the famous _ , happened to be visiting my father at the time and, hearing me crying over the death of my bird, explained what had occurred: "A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity." Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free. The most important lesson the boy learned from the incident is that _ .
Choices:
A. birds put in a cage won't live long

Beauty has always been regarded as something admirable. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive persons. But in the executive circle , beauty can become a liability. While attractiveness is a positive thing for a man's rise, it is harmful to a woman. Handsome male executives were considered as having more honesty than plainer men; effort and ability were thought to be the reasons for their success. Attractive female executives were considered to have less honesty than unattractive ones; their success was attributed not to ability but to factors such as luck. All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Why are attractive woman not thought to be able? An attractive woman is thought to be more feminine and an attractive man more masculine than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally masculine position appears to lack the "masculine" qualities required. This is true even in politics. Anne Bowman recently published a study on the effects of attractiveness on political candidates . She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked lo rank them again, in the order they would vote for them. The results showed that attractive males completely defeated unattractive men, but the woman who had been ranked most attractive always received the fewest votes.

Robert Louis Stevenson was born in Edinburgh in Scotland in 1850. He had to end his college studies because his health was poor. He began to travel, looking for a place that was good for his health. And he wrote about his travels. Inland Voyage(1878) was about journeys by canoe on the rivers and canals of Belgium and France. Travels with a Donkey in the Cevennes followed it in next year. People loved his travel books, and they also found his poems beautiful. In 1879 he travelled to California in a very uncomfortable ship and then by train across the United States to San Francisco. He married in California, but his poor health made him and his wife travel again. Readers of his travel books and poetry were surprised when Treasure Island came out in 1883. It was not at all like his earlier writing, but both children and grown-ups loved it. Treasure Island was finished in Switzerland. Stevenson then continued to travel. He loved the islands of the southern Pacific Ocean, and he found that his health was better there. In the end, he and his wife made their home in Samoa. It was there that he wrote Kidnapped(1886), the story of David Balfour and Alan Breck. It was followed (but not immediately) by Catriona, which continues the story of David Belfour and tells of other exciting adventures of David and Alan, and of David's love for Catriona Drummond. In between the two stories about David Belfour came another surprising book, the "thriller" called The Strange Case of Dr Jekyll and Mr Hyde. Stevenson died in Samoa in 1894, and he is buried there.

One man tells of driving on a long and lonely road, the last 65 miles of it unpaved, in order to watch Indian dances in the state of Arizona.After the dances, he returned to his car only to find that it had a flat tire.He put on the spare and drove to the only service station in that town. "Do you fix flats?" he inquired of the attendant. "Yes," came the answer. "How much do you charge?" he asked. With a twinkle in his eye, the man replied, "What difference does it make?" This is what has been called a "Hobson's choice".A Hobson's choice is a situation that forces a person to accept whatever is offered or go without. According to Barbara Berliner, the phrase was inspired by sixteenth-century entrepreneur Thomas Hobson.There was no choice by the customer -- it was strictly Hobson's choice. But often we really have a choice, and the choice does make a difference.We may not always believe it.We may feel as if we have no choice, but almost always there is a choice in the matter.And when we realize that we do most things by choice, then we are taking control of our own lives. Someone challenged me to try an experiment that completely changed my perspective(,)."For the next seven days," he said, "remove the words 'I have to' from your vocabulary and say 'I choose to'.Don't say, 'I have to work late tonight'.Instead, say, 'I choose to work late'.When you choose to do it, you take control of your life.Instead of saying 'I have to stay home', try 'I choose to stay home'.The way you spend your time is your choice.You are responsible.You have control." In just seven days I was no longer saying "I have to" and I felt better about my decisions.I learned that there is very little in my life I actually have to do.You and I decide to do certain things because we believe that it will be for the best.When we remove "I have to" from our vocabularies, we take control.

About 6,000doctors in theprefix = st1 /Philippinesare studying to become nurses so they can find higher-paying jobs abroad, Health Secretary Francisco Duque says. This was up from 2,000 doctors who studied to become nurses last year, Duque said. The exodus of doctors and nurses had created a "threatening situation for our health care system" and a task force had been established to examine the potential impact, he said. The team was working on a bill which would require doctors to practice in thePhilippinesfor at least three to four years before they were able to work abroad. "I think the problem really is the migration of doctors. We have so many nurses now, more than enough to fill up(vacancies). But our doctors are leaving," Duque said. A study by the University of thePhilippineshad found that between 2000to 2003 more than 50,000 Filipino nurses went abroad to work. A doctor working in a government hospital in thePhilippinesearns only about 25,000 pesos(446 dollars) a month. A doctor could earn around 8,000dollars a month while working as a nurse overseas. Even lawyers, accountants and engineers are enrolling to brain as nurses. Filipino nurses are in demand in Europe, the United States, the Middle East and even closer to home, such as in Singapore and Japan. However, Health officials have warned the country faces a "medical apocalypse" if it continues to lose its health professionals to jobs abroad. What is the aim of this short passage?

BUKHANNON, West Virginia--Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident. Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates on the rescuers' progress. The miners were trapped at about 6:30 and many families weren't informed of the accident until about 10 a.m-more than three hours after it happened."It's very upsetting, but you've got to be patient, I guess," said John Helms, whose brother, Terry, was trapped in the mine. The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine's entrance, said Roger Nicholson, general counsel from International Coal Group. At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p.m.Another team entered the mine about 30 minutes later. He said the crew was very experienced, with some members having worked underground for 30 to 35 years.The miners were equipped with about one hour of breathable oxygen each.The company has not released the names of the miners. The teams test the air about every 500 feet, and have to disconnect (remove) the power to the phones they use to communicate with the surface before doing that." We don't want to be energizing anything if it's in an atmosphere with burnable gases," Kips said. The cause of the explosion was not immediately known.High levels of carbon monoxide were discovered shortly after the explosion, which delayed rescue efforts, but those levels have since subsided , authorities said. If the first team advanced at an average speed, they could dig about _ per hour.

The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline. The term comes from the glacial activity of the Ice Age. At that time, the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier descended, however, it applied enormous force on those mountains, and they sank into the sea. As the mountains sank, ocean water charged over the lowest parts of the remaining land. And the highest parts of the former mountain range, nearest the shore, remained as islands. Marine fossils found here are 225 feet above sea level indicating the level of the shoreline prior to the glacier. The 2,500-mile-long rocky and jagged coastline of Maine keeps watch over nearly 2,000 islands. Many of these islands are tiny and uninhabited, but many are home to blooming communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands left behind by the glacier. Measuring 16 miles by 12 miles, Mt. Desert was very nearly formed as two distinct islands. It is split almost in half by Somes Sound, a very deep and very narrow stretch of water seven miles long. For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, has afforded summer homes for the wealthy. Recently, though, Bar Harbor has become a new arts community as well. But the best part of the island is the unspoiled forest land known as Acadia National Park. Since the island sits on the border between two different geographical zones, the park supports the plants and animals of both zones. It also lies in a major bird migration lane and is a resting spot for many birds. The establishment of Acadia National park in 1916 means that this natural monument will be preserved and that it will be available to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, hiking, cycling, and boating. Or they may choose to spend time at the museum learning about the Stone Age inhabitants of the island. The large number of small islands along the coast of Maine is the result of _ .

The United States will introduce a new exam system for students who seek to study in the USA and other English-speaking countries, Xinhua News Agency reported from New York. The exam, which means a great change from the English level test, was introduced by Theresa Jen, associate director of the International Service of the USA College Board, America's leading educational organization. "The Advanced Placement International English Language (APIEL) will be offered for the first time all over the world on May 10, 2012," said Jen. However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL (Test of English as a Foreign Language), the GRE (Graduate Record Examination), or the IELTS (International English Language Testing System). "I have never heard of such a test and I would prefer the IELTS if I need another exam," said Xu Jingyan, a graduating student from Beijing University, who wants to study in England and has already taken the TOEFL. Most of Xu's classmates have never heard of the APIEL."The APIEL is made for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada and Australia." Jen said. "The APIEL will be used," said Jen, "because the TOEFL can no longer perfectly show the students' abilities of using English." Xinhua reported that a large number of foreign students who had high scores in TOEFL exam turned out to be very ordinary educational performers after being admitted. "Compared with the TOEFL, the APIEL measures a student's ability to read, write, speak and understand 'English through testing his or her skills in listening comprehension, speaking with fluency, and writing in an organized way." Jen said. The APIEL is designed for students who want to study in English-speaking countries, such as _ .

Although it was autumn, the snow was already beginning to fall in Tibet. Our legs were so heavy and cold that they felt like blocks of ice. Have you ever seen snowmen ride bicycles? That's what we looked like! Along the way children dressed in long wool coats stopped to look at us. In the late afternoon we found it was so cold that our water bottles froze. However, the lakes shone like glass in the setting sun and looked wonderful. Wang Wei rode in front of me as usual. She is very reliable and I knew I didn't need to encourage her. To climb the mountains was hard work but as we looked around us, we were surprised by the view. We seemed to be able to see for miles.

mmlu | Question:
Once there was an 11-year-old boy who went fishing with his father in the middle of a New Hampshire lake. On the day before bass season opened, they were fishing early in the evening, catching other fish with worms. Then the boy tied on a small silver lure and put it into the lake. Suddenly he felt that something very big pulling on the lure. His father watched with admiration as the boy skillfully brought the fish beside the bank. Finally he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass. The boy and his father looked at the big fish. The father lit a match and looked at his watch. It was 10 p.m.--two hours before the season opened. He looked at the fish, then at the boy. "You'll have to put it back, son," he said. "Dad!" cried the boy. "There will be other fish," said his father. "Not as big as this one," cried the boy. He looked around the lake. No other fishermen or boats were in sight in the moonlight. He looked again at his father. Even though no one had seen them, nor could anyone ever know what time he had caught the fish, the boy could tell from his father's voice that the decision couldn't be changed. He threw the huge bass into the black water. The big fish disappeared. The boy thought that he would never again see such a big fish. That was 34 years ago. Today the boy is a successful architect in New York City. He often takes his own son and daughters to fish at the same place. And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish ... again and again ... every time he has an ethical decision to make. For, as his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult. The successful architect went fishing with his children at the same place because _ .

After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days. The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds "this is the only paint like it in the world, and tests prove it works." Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period. Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 US to the price of a car. It plans to use its new chemical mixture only on its _ in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores as well. What can be inferred from the article?
Choices:
A. The paint was developed by Nissan Motor Company.
B. The paint might work better in summer than in winter.
C. The mark on the car could disappear as soon as the paint is applied.
D. The paint is very popular in Japan. | B |

Can you imagine that several hundred years ago, tomatoes were seen as _ food in Europe? What made Europeans believe this was John Gerard's publication of Herbal in 1597. Gerard wrote: "The leaves and stalks of the tomato plant are toxic." Undoubtedly, Gerard's opinion was based on a misunderstanding of tomatoes. But his opinion was widely spread in Britain and North America for over two hundred years. In the late 1700s, a lot of Europeans held more fears for tomatoes. A nick name for the fruit was "poison apple" because it was believed that aristocrats got sick and died after eating them. But the actual reason was the pewter plates they used. Since tomatoes are high in acidity, when placed on the plates, the lead in the plates would dissolve . This caused many deaths. Unluckily, no one knew this at that time. So the innocent tomatoes were picked as the killer. Today, more than one and a half billion tons of tomatoes are produced every year around the world. Tomatoes are cooked in various ways. This healthy and tasty food finally wins its innocence back. Which of the following can be the best title for this passage?
Choices:
A. Europeans' fears for tomatoes
B. History of tomato planting
C. Why do people eat so many tomatoes
D. How did the tomato prove its value | A |

When asked what they want for a gift, most teens would say a CD player, or maybe an iPod, but I want Lego. I received my first set for my fifth birthday, a tiny pizzeria with an umbrella and a delivery truck. Since then my collection has expanded rapidly and I have built skyscrapers, constructed spaceships and designed submarines. There is a small area in my house designated as The Lego Room. Beyond its door, I fantasize and govern my own small world of castles, modem cities, and thousands of Lego people. Each time I enter The Lego Room, a new story is created. Once, a friend asked to tour this room. Amazed by my Star Wars models, he reached for a ship and accidentally knocked over a restaurant, breaking it to pieces! This disaster became an opportunity to rebuild and I fashioned a two-story food court with a McDonald's, pizzeria, and drive-thru. It was better than the original! Ideas for new constructions fill my head and I write them down in a sketchbook. Lego represents a creative consistency in my life, much as an artist has his canvas and a musician, his violin. Lego has taught me to be an architect, engineer, governor, economist and so on. Lego has provided the building blocks of my future, developing my math skills and ability to follow complex directions. As I build new worlds, brick by brick, I imagine my own possibilities and opportunities. Through the "lives" of my Lego friends, I have been able to act out all kinds of experiences. They have served as a link between my childhood and manhood. My friends say I'm childlike and there is truth to that, but perhaps we should all find a way to keep in touch with our childhood. Lego is mine. What can we infer from the passage?
Choices:
A. The author likes collecting anything but Lego.
B. The author wants to be an architect.
C. The author has benefited a lot from playing with Lego.
D. The author doesn't want to grow up. | C |

There are millions of people throughout the world who are either born blind or have become blind over the course of their lifetimes. It is unfair to take away the visual beauty of the world from these people. Doctor Humayun has created the world's first bionic eye that could change the life of every blind people in the world. Doctor Mark Humayun is a well respected professor at the Doheny Eye Institute in California. He has been working for years on creating a bionic eye that would allow blind people to see images just like a normal person does. His idea of the bionic eye is actually an eye that has been built in a small video camera. The test results show the bionic eye has given blind patients the amazing ability to see the scientists doing the tests. But the images are still blurry and we need much work before the eye actually becomes a regular implant into blind people. Humayun believes that he can go into production with the bionic eye over the next three to five years. A closer look at the bionic eye is amazing. The patient wears a special set of eyeglasses. All the signals are passed to the implanted eye. It's done by wireless technology. Humayun has created an invention that could change the lives of millions of people. Imagine a world in which someone would no longer fear about being blind. This could be considered a technological achievement. How long will it take Doctor Humayun to produce his bionic eye?

Does your local town have a nickname? If so, what does it say about the area and the people who live there? Many cities are recognized across the world by their unofficial names. New York is the Big Apple, London is the Big Smoke, and Los Angeles is famously called La La Land. Now, as part of English Language Day on Wednesd ay, two British organizations, the English Project and Ordnance Survey, are launching an interactive project which aims to identify the nicknames which people use in their daily lives for the places which they like or dislike. "The name that people create for a place forms a connection with feelings," explains Winchester University's Professor Bill Lucas, a patron of the English Project. "So Basingstoke becomes Amazingstoke; Swindon is known as Swindump and Padstow, hometown of chef Rick Stein, is nicknamed Padstein." Basingstoke is a town in central England. The local nickname, Amazingstoke, shows the love that locals seem to have for the area. Swindon, on the other hand, is sometimes called Swindump, showing that some people think it's a dump ( ). Stanford Le Hope in Essex is called Stanford No Hope by locals. And Padstow in Cornwall is so closely connected with the local famous person Rick Stein that it's become known as Padstein. Since launching the online survey last week, the creators have already received 3,000 alternative titles for places and landmarks. As well as creating what promises to be a fascinating resource of nicknames, there is a practical side to the project. "With the huge variety of place nicknames that exist, we could never hope to collect them all ourselves," says Glen Hart, Ordnance Survey's head of research. "But the information from the project could prove vital. Organizations like the emergency services rely on our information when responding to 999 calls, so by having the most complete set of nicknames we could help the emergency services quickly locate the right place, and maybe even save lives." What is the passage mainly about?
Choices:
A. Some stories about nicknames for places.
B. Activities launched by two British organizations.
C. A survey of nicknames for places.
D. The attractiveness of place nicknames. | C |

MEXICO CITY: A jetliner from the beach resort of Cancun was briefly hijacked as it landed in Mexico City on Wednesday. The hijackers released all passengers shortly before federal police stormed the plane, and the crew emerged unharmed moments later. Police, who did not fire a single shot, led as many as eight handcuffed men away from the airplane, which was isolated at the end of a runway in an area designed for emergencies. The hijackers' motive was unclear, though Mexican news media initially identified them as Bolivians demanding to speak with Mexican President Felipe Calderon. US, French and Mexican citizens were among the 112 passengers and crew on Aeromexico Flight 576, according to a US official who had been briefed on the situation. The official was not authorized to discuss the case and spoke on condition of anonymity. Mexico's transportation and communications secretary, Juan Molinar, said there was no bomb on the airplane, although some passengers said one of the hijackers held a package that resembled an explosive device, and a bomb squad was later seen near the airplane. He did not immediately identify the hijackers or speculate on their motive. "Various people who participated in the act have been detained and we are investigating," Molinar said. The attorney general's office said it was opening an investigation into terrorism and kidnapping but did not specify how many people could be charged. Mexican news media initially reported the hijackers were Bolivian, but Bolivia's ambassador to Mexico, Jorge Mancilla, said Mexican authorities had no evidence that was the case. Mancilla said sources told him they could be Colombian or Venezuelan. Several passengers told reporters they did not notice a non-Mexican accent. Passenger Rocio Garcia told the Televisa network that the pilot made an announcement after landing in Mexico City that the airplane was being hijacked. Passengers said the hijackers never communicated with them directly. "These were scary moments," she said. She said she saw one of the hijackers whom she described as a well-dressed, older man. "He looked fine, like a normal passenger," she said. Passenger Daniel Hernandez said he saw a hijacker carrying a Bible. From what Juan Molinar said we can learn that _ .
Choices:
A. police were still trying to identify a possible bomb
B. passengers succeeded in stopping the explosion
C. a frightening bomb was found later on the airplane
D. several Mexicans were involved in the hijacking | A |

You've probably grown accustomed to texting in the glow of a mobile phone screen. Well, there's some good and bad news coming for those of you who spend hours speedily tapping messages to one another. The good news is that the hours you spend face-to-phone are paying off. You may have become fluent in a second language. The bad news, however, is that this language is texting. Worse still, there isn't yet a texting section in your school exams, so you'll need to work harder to recover the grammar skills you might be killing with every LOL and BRB (Be right back). A new study confirms what many parents suspect. The more kids send and receive texts, the poorer their grammar skills become. With "the culture of mobile communication--quick back and forth , there are compromises on traditional, cultural writing", said S. Shyam Sundar, professor of Pennsylvania State University, which conducted the study. "Techspeak", as Sundar and his research partner Drew P. Cingel call it, has become so prevalent among young users that it's changing their foundation of basic grammar. "Routine use of textual adaptations by current and future generations of 13-to-17-year-olds may serve to create the impression that this is normal and accepted use of the language, "they said in their published findings. It seems teenagers are unable to "code switch-shift" between standard grammar and the abbreviations used in text messages, Sundar said. These abbreviations have become the real words for them now. However, linguists aren't particularly disturbed by the trend, Sundar added. "The linguists will tell you the language is very dynamic. " Still, students have exams to worry about. Here's a sample of the questions, so you can test yourself to see how texting has affected your grammar: *During the flood, we (dranked, drank, drunk, drunked) bottled water. *Fortunately, Jim's name was (accepted, excepted) from the list of those who would have to clean bathrooms because he was supposed to go downtown to (accept, except) a reward for the German Club. *The dress is so large that it is (lose, loose) on me when I wear it!

"I've changed my mind.I wanted to have a telescope,but now I want my dad back." Lucien Lawrence's letter to his father for Christmas written after his father had been knifed to death outside his school gate,must have touched everyone's heart.Lucien went on to say that without his father he couldn't see the stars in the sky.When those whom we love depart from us,we cannot see the stars for a while. But Lucien,the stars are still there,and one day,when you are older and your tears have gone,you will see them again.And,in a strange way,I expect that you will find your father there,too,in your mind and heart.I find that my parents,who died years ago,still figure in many of my dreams and that I think of them perhaps more than I ever did when they were alive.I still live to please them and I'm still surprised by their reactions.I remember that when I became a professor,I was so proud,or rather so pleased with myself that I couldn't wait to cable my parents.The reply was a long time in coming,but when it did,all my mother said was "I hope this means that now you will have more time for the children!" I haven't forgotten.The values of my parents still live on. It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care.Would I have been as ready as Philip Lawrence have been to face the aggressors,and to lay down my life for those in my care?How many people would want me back for Christmas?It's a serious thought,one to give me pause. I pray silently,sometimes,in the dead of night,that ancient cry of a poet "Deliver my soul from the sword,and my darling from the power of the dog." Yet I know the death comes to us all,and sometimes comes suddenly.We must therefore plan to live forever,but live as if we will die tomorrow.We live on,I'm sure,in the lives of those we love,and therefore we ought to have a care for what they will remember and what they will treasure.If more parents knew this in their hearts to be true,there might be fewer knives on our streets today.

A. Proud.

mmlu | Question:
The world's population is more mobile today than ever before. In 2010, more than 200 million people left their home countries to live in a new country. This is about 3 percent of the total world population. Some experts believe that number will swell to 400 million by 2050. Rates of immigration have remained strong for the last 300 years, but patterns of immigration have changed since World War II. The backgrounds and experiences of today's immigrants are different from those of the typical European immigrant of the nineteenth and early twentieth centuries. Contemporary immigrants range from unskilled laborers to highly skilled professionals, and they come from and go to countries all over the world. In the nineteenth century and until World War II, immigration was primarily in one direction- from the Old World to the New World. This is no longer the case. Countries such as Russia and China, which have long been, and continue to be, significant source countries, are now also destination countries. There is also considerable mobility inside regions, such as from one European country to another, or among the countries of the former Soviet Union. In spite of such differences, the push and pull factors for immigration remain essentially the same as they were 100 years ago. Most people move to another country because they want a better life. For the majority of immigrants, this means better economic conditions. As in past generations, a labor shortage in one country often draws workers from another country, especially if wages are significantly higher. In some small countries, for example, Qatar, United Arab Emirates, and Kuwait, there are more jobs than citizens. The demand for labor is so high that the majority of the population consists of foreign-born workers, ranging from highly skilled engineers and financial experts to domestic and construction workers. In traditional destination countries, such as the United States, however, labor needs have changed. Today, although there is still demand for unskilled labor, there is increasing demand for people with a high level of skill and education. The need for less skilled labor has shifted to other countries. As work on farms and in industry in the United States and Canada once drew workers from all over the world, now work in factories in Taiwan and south Korea attracts workers from Vietnam, the Philippines, and Cambodia. Most global immigration is legal: however, a large number of people also move across national borders illegally in pursuit of employment. Experts estimate that about 15 to 20 percent of immigrants worldwide are in their new countries illegally. The United States has the largest number of these immigrants, followed by South Africa, with significant numbers also in Northern and Western Europe and Mexico. These immigrants face particular challenges because they often must hide from the authorities who might deport them back to their home countries. Their illegal status also means that employers may take advantage of them by forcing them to work longer hours and paying them less than the legal minimum wage. Although economics remains the most important motivation in all forms of immigrant, other factors are also important. Some people decide to leave their home countries because their actions or political beliefs make it dangerous for them to remain. Others choose to leave because their home country has become too dangerous and unstable, often because of war or political unrest. They wish to find a place that is secure for themselves and their families. Education is also a significant factor for many modern immigrants. They want to raise their children in a place where they can get a good education, which, in turn, they hope will provide them with better prospects for the future. Finally, family and community ties also play a role in immigration decisions. As in the past, once a group of people from one country establishes a community in a new country, more people from that country is likely to follow. The pattern, direction, and rate of immigration may change as the global economy changes. However, as long as life in a new country is more attractive than life in the old country, immigration will continue. Which is not the factor contributing to the immigration?
Choices:
A. Education
B. Political instability
C. Religious freedom
D. Family and community connections | C |

Martin Lynch, an American businessman, had been going on vacation to a small Mexican fishing village for a number of ears. One morning while going for a walk along the beach, he saw his friend Pablo Perez, a local fisherman. Martin watched Pablo _ his boat and pack the fish in a box. Martin noticed Pablo was smiling and looked very happy. He could also see several large fish in the boat. Martin greeted Pablo and asked how long it took to catch the fish. "Just a few hours," replied Pablo. Martin asked, "Why didn't you stay longer and catch more fish?" "I have enough for my family," Pablo said. "And what do you do with the rest of your day?" asked Martin. "I take a nap, play with my children, spend time with my wife, and go into the village to see my friends and play cards, I have a full and busy life." Martin explained that if Pablo worked longer hours and caught more fish, he could make more money. With the extra money, Pablo could buy more boats and catch money more fish. By selling the fish, Pablo could open his own factory and sell direct to supermarkets. "Then what?" asked Pablo. "Well you would probably have to move to Mexico City to run the business. Finally, you would be able to sell your business and make millions of dollars," replied Martin. "How long will that take?" asked Pablo. Martin thought for a while and said it would probably take at least 15 years. "And then what" asked Pablo. "Well, that's the best part," Martin said. "You will be able to retire, buy a house near the ocean, sleep longer, play with your children, spend more time with your wife, see your friends, and play cards." How can the fisherman make more money in the businessman's view?

The triathlon promises to be one of the most popular Olympic sports.Recently it has drawn huge crowds attracted by athletes swimming 1,500m,cycling 40km,then running 10km without stopping.But what makes an attractive 17yearold girl give up everything for the doubtful pleasure it offers? Melanie Sears has not yet learnt those oftenrepeated phrases about personal satisfaction,mental challenge and higher targets that most athletes use when asked similar questions."You swim for 1,500m,then run out of the water and jump on your bike,still wet.Of course,then you freeze.When the 40km cycle ride is over,you have to run 10km,which is a long way when you're feeling exhausted.But it's great fun,and all worth it in the end," she says. Melanie entered her first triathlon at 14 and she won the junior section.Full of confidence,she entered the National Championships,and although she had the second fastest swim and the fastest run,she came nowhere."I was following this man and suddenly we came to the sea.We realised then that we had gone wrong.I ended up cycling 20 kilometres too far.I cried all the way through the running." But she did not give up and was determined that she never will."Sometimes I wish I could stop,because then the pain would be over,but I am afraid that if I let myself stop just once,I would be tempted to do it again."Such doggedness draws admiration from Steve Trew,the sport's director of coaching."I've just been testing her fitness," he says, "and she worked so hard on the running machine that it finally threw her off and into a wall.She had given it everything,and she just kept on." Melanie was top junior in this year's European Triathlon Championships,finishing 13th."I was almost as good as the top three in swimming and running,but much slower in cycling.That's why I'm working very hard at it." She is trying to talk her longsuffering parents,who will carry the PS1,300 cost of her trip to New Zealand for this year's world championships,into buying a PS2,000 bike,so she can try 25km and 100km races later this year. But there is another price to pay."I don't have a social life,"she says."After two hours' hard swimming on Friday night,I just want to go to sleep.But I phone and write to the other girls in the team."

HANGZHOU, China -- Millions of Chinese basketball fans who were upset about the retirement of Yao Ming, are excited to see another even more shining star, Jeremy Lin, rising from the N.B.A and becoming a household name all across China. "We are amazed by Lin Shuhao's magic performance and should cheer him on," one Internet user wrote. "His sport shirts have sold out, even including the counterfeit ones," said Zheng Xiaojun, a 24-year-old clerk. Lin's amazing success over the last month has caught the imagination of the Chinese. He has been particularly popular here in northern Zhejiang province, from which his grandmother went to Taiwan in the late 1940s. Cai Qi, a well-known micro blogger, posted a message on micro blog over the weekend stating that Lin's hometown is Jiaxing, a city near Hangzhou where Lin's grandmother grew up. Cai Qi's nephew Yu Guohua, a 56-year-old factory worker, is Lin's closest still living in northern Zhejiang. He said in a telephone interview that Lin had come to play basketball with the Jiaxing High School team last May and had been surrounded by admirers. Yu said he did not have a chance to meet Lin in the crowd, but managed to speak with his family. "His father was very supportive of Lin's playing basketball, but his grandmother was not, for fear he would be injured," Yu said. Lin may owe his height, 6 feet 3 inches, to his grandmother's family, Yu said. Chen Weiji, the father of Lin's grandmother, was well over 6 feet and all of Chen's children were tall as well, he said. The N.B.A. believes that 300 million people in China play basketball. The retirement last year of Yao Ming took its main Asian draw away from the N.B.A. But Lin's appearance has helped the league remain a hot topic of Chinese online chatter. Lin's success in N.B.A has _ .
Choices:
A. attracted more Chinese children to play basketball as a career
B. drawn Chinese people's attention back to the league
C. helped his hometown develop sports shirts business
D. helped his hometown attract more foreign visitors | B |

Scientists have found that human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper The Telegraph. The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District. They found that on the beach, eyes are exposed to a daily 260 kilojoules of UV a square meter compared to 658 kilojoules in snow-covered areas. The findings are supported by the Japan Meteorological Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height. Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes. If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes. Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness. Which of the following statements is TRUE according to the passage?
Choices:
A. Too much eye exposure to UV rays may cause total blindness.
B. Short-time exposure of the eyes to UV rays doesn't harm them at all.
C. Most people know that UV rays harm the eyes as well as the skin.

Old people are always saying that the young are not what they were. The same comment is made from generation to generation and it is always true. It has never been truer than it is today. The young are better educated. They have a lot more money to spend and enjoy more freedom. They grow up more quickly and are not so dependent on their parents. They think more for themselves and do not blindly accept the life goals of their elders. Events which the older generation remembers vividly are nothing more than past history. This is as it should be. Every new generation is different from the one before. Today the difference is very noticeable indeed. The old always believe that they know best for the simple reason that they have been around a bit longer. They don't like to feel that their values are being questioned or threatened. And this is exactly what the young are doing. Wouldn't people work best if they were given complete freedom and responsibility? And what about clothing? Who said that all the men in the world should wear dull grey suits and very short haircuts? Who said that human differences can best be solved through normal politics or by violent means? Why have the older generation so often used violence to solve their problems? Why are they so unhappy and guilty in their personal lives, so occupied with mean ambitions and the desire to collect more and more wealth? Haven't the old lost touch with all that is important in life? These are not questions the older generation can shrug off lightly. Their record over the past forty years or so hasn't been exactly spotless. Traditionally, the young have turned to their elders for guidance. Today, the situation might be opposite. The old--if they are prepared to admit it--could learn a thing or two from their children. One of the biggest lessons they could learn is that enjoyment is not wrong. Enjoyment is a principle one could apply to all aspects of life. It is surely not wrong to enjoy your work and enjoy your free time. It is surely not wrong to live in the present rather than in the past or future. This emphasis on the present is only to be expected because the young have grown up under the shadow of the bomb: the constant threat of complete annihilation . This is just what the older generation has passed down to them. Which of the following about the young is NOT mentioned in the article?
Choices:
A. Better educated.
B. Richer.
C. Independent.
D. Hard-working | D |

Sunshine is a great film, which takes us on a voyage into space when mankind is in danger. In 2057, our Sun is dying and mankind faces extinction. A spaceship named IcarusII, carries an enormous bomb to return life to the dying star. As the movie begins, the spacecraft is approaching the Sun. Suddenly, the operating system is out of control;then the crew receive a frightening signal from the original IcarusI which was sent to carry out the same task seven years ago. Should the crew continue flying to the Sun in the endangered ship? The question is not so much about whether any crew member can survive--the chances of that hardly exist--but should they try to grab the other bomb in IcarusI and take it to the Sun? Two shots at saving mankind are obviously better than one. After the decision is made, a crew member makes a mistake that places the mission in extreme danger. More accidents occur, and the crew face a difficult situation:there isn't enough oxygen for them on the ship. www.ks5u.com Among the most exciting scenes is a space walk by Capa and Kaneda when the ship's shield is damaged and must be inspected and repaired. Then when docked with IcarusI, the crew find it will be difficult for them to achieve the goal of the voyage. The film reaches its climax when the computer in IcarusI detects the presence of an unknown crew member. Indeed, the major task of the flight is to take back the world by restarting the failing Sun.

GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water. But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae outbreak in Taihu Lake, China's third largest freshwater lake and the source of drinking water for 4 million Wuxi residents ,water from the city's taps became dark and smelly. "I can't believe there is no water for drinking, let alone cooking and washing,"said Gu. The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor in the water. "High temperature and a lack of rain in the past few months helped the growth of algae,"said Zhang Lijun, an official from the State Environment Protection Administration. "However, pollution from human activity should be most blamed for the disaster." Taihu Lake is surrounded by many small factories, which _ in the 1980s.Inthe 1990s,many foreign-funded companies joined in. The industries prospered ,Wuxi has grown into one of the wealthiest cities in East China. But that came at the price of pollution. The lake was treated like a waste dump ,with factories emptying industrial waste and untreated sewage into it. Although, after the government's effort, life in the city has gone back to normal, the one-week crisis rang a bell for the government and local people."It's time to rebuild the beauty of nature, or our lives will be at risk,"said Gu.

Millions of people die of hunger in Southern Africa every year, but when prefix = st1 /Zambiawas offered thousands of tons of free maize by theUS, the government politely said no. "We don't know whether the food is safe," said Zambia's Commerce, Trade and Industry Minister Dipak Patel. His worries are shared by countries around the world that are _ aboutAmerica's genetically modified (GM) crops. Just last week, EU member nations were discussing whether or not to import GM sweet corn from theUS. Ever since people started farming, they have tried to crossbreed plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other. But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature. This means they can make crops more productive and resistant to disease by adding genes from other species. They can also create food with special characteristics, such as "golden rice", which is enriched with vitamin A. But many people believe GM foods are a health risk. "If left to me, I would certainly not eat GM foods," said Scottish scientist Arpad Pusztai. "We are putting new things into food which haven't been eaten before. The effects on the immune system are not easy to predict." At the moment, the official argument is that GM foods "are not likely to present risks for human health". But there are still many questions to be answered as the foods are produced in different ways. Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. Which of the following statements is NOT true about GM foods?

mmlu | Question:
The most common use of intelligence test scores is to predict degree of academic success. Such scores are used in some communities as bases for admitting able children to schools at ages younger than normal, and they are very generally used to determine admissions to schools beyond public secondary school. Another use common in elementary schools involves comparing such scores with performances in various subjects to identify children who are working below capacity. The greatest problem in using intelligence tests for the purpose of prediction is that no dependable criterion of their accuracy exists. The ideal criteria would be objective and reliable achievement tests following instruction in each subject, but there are few such tests, especially at the college level. Studies have shown that correlations between intelligence tests and achievement tests in various subjects through secondary school range roughly from 0.5 to 0.8. Such correlations are fairly high, but they do not suggest anywhere near complete agreement. At the college level there are two major tests used as criteria of admission. By far the more important is the College Entrance Examination, constructed by the Educational Testing Service authorized by the College Entrance Examination Board. These tests are returned to the Educational Testing Service for scoring, and the results are then made available to the various colleges authorized by the students to receive them. The second test of this type is the American College Test, which operates in essentially the same fashion. Both tests constitute measures of certain skills, abilities, and knowledge that have been found to be related to success in college. Their correlations with academic success are limited for three outstanding reasons. First, measures of achievement in college are themselves perhaps no more reliable than those in elementary and secondary schools. Second, intellectual factors do not alone determine academic success, especially at the college level. Many students drop out of schools because they are inadequately motivated or because they dislike the instructional programme. Third, correlations are lowered because the use of such tests for denying admission to some students means that the range of scores for those admitted is restricted, and such restriction tend to reduce correlation. The ideal criteria in using intelligence tests for prediction should be _ .

Monitoring the mood of a pet dog could be used as an early warning sign that an elderly owner is struggling to cope, a new report has claimed. Researchers placed movement sensors on dogs to track their behaviour and identified 17 distinct activities, including chewing, barking, sitting and digging. This allowed them to map the normal behaviour of a healthy, happy dog, which means any changes can be monitored and could indicate an issue with their owner. Nils Hammerla, part of the team from Newcastle University, said, "Humans and dogs have lived together in close relationships for thousands of years, which has led to strong emotional and social mutual bonds." "A dog's physical and emotional dependence on their owner means that their well-being is likely to reflect that of their owner. Any changes such as the dog being walked less often, perhaps not being fed regularly, or simply demonstrating "unhappy" behaviour could be an early indicator for families that an older relative needs help. This is the first system of its kind which allows us to remotely monitor a dog's behaviour in its natural setting." The team of academics, who presented their findings at the 2013 UbiComp conference in Zurich, created a hi-tech, waterproof dog collar for the study. Dr Cas Ladha, who led the study, said: "A lot of our research is focused on developing intelligent systems that can help older people to live independently for longer. But developing a system that _ family and carers that an older relative is well without intruding on the individual's privacy is difficult. This is just the first step but the idea behind this research is that it would allow us to support people without the need for cameras." A range of dogs was used for the study, as the team needed to map distinct behaviours that correlated between different breeds. Which of the following could be the best title for the text?

If they are not working, they are jogging, or playing tennis or golf, or taking courses to improve their minds or bodies -or they are parked in front of the TV. Sitting in front of the TV isn't sitting - it's watching. People used to sit a lot. You would walk down the street or drive down the road, and there they would be, out on the doorsteps, sitting. You could go down to the store and sit on the bench out front in the summer or around the fire in the winter. There were sitting benches out in the town square. At the garage, there were straight-backed chairs. There among the oilcans and tries and spare parts, you could kick back and sit. Houses used to have sitting rooms, where the grown ups would go after Sunday dinner. Mom and Dad, Grandpa and Aunt Ruby would sit and digest the fried chicken and talk about Aunt Ethel's illness, and how well the minister did today. Outside, the children would play, and the afternoon would pass by in a comfortable haze . That sort of thing looks like doing nothing.

In the depths of my memory, many things I did with my father still live. These things come to represent, in fact, what I call joy and love. I don't remember my father ever getting into a swimming pool. But he did love the water. Any kind of boat ride seemed to give him pleasure. And he loved to fish; sometimes he took me along. But I never really liked being on the water, the way my father did. I liked being in the water, moving through it, having it all around me. I was not a strong swimmer, or one who learned to swim early, for I had my fears. But I loved being in the swimming pool close to my father's office and spending those summer days with my father, who would come by on a break. I needed him to see what I could do. My father would stand there in his suit, the only person not in swimsuit. After swimming, I would go inside his office and sit on the wooden chair in front of his big desk, where he let me play with anything I found in his top desk drawer. Sometimes, if I was left alone at his desk while he worked in the lab, an assistant or a student might come in and tell me perhaps I shouldn't be playing with his office things. But my father always showed up and said easily, "Oh, no, it's fine." Sometimes he handed me coins and told me to get myself an ice cream... A poet once said, "We look at life once, in childhood; the rest is memory."
