mmlu | Question:
During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does. In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one's brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain. It has been found that one's brain usually works _ .
Choices:
A. faster when he is old
B. a little now and a little then

What is a library for? Most libraries have books and other things to read. Many of them have things to listen to. Some libraries even have computers. Very few people would think of a library as a place to live in. One library in New York City turned into a home for 250 people for a few days. These were all people near the library. They slept on the floor. Why did the people move into the library? The people moved into the library because the city wanted to close it to save money. These 250 New Yorkers loved their library. They didn't want to lose it. So they moved in. They knew that the library couldn't be closed if they were living inside it. At last the city agreed to keep the library open, and the people all went home. The people in the story _ .

mmlu | Question:
Eight-year-old Bethany and seven-year-old Eliza are having a great time jumping around in the orchard of their home in a village near Penrith. They can play any time they like because they don't go to school. Instead, they are educated at home by their parents, Paul and Veronika Robinson. But they don't have lessons, have never used a timetable and learn only what and when they want to learn. "I want my kids to have freedom in their childhood, not spend it in an institution," says 37-year-old Veronika, "School is all about control and following the rules." Veronika and her 56-year-old husband Paul have never experienced the daily rush to get dressed and out of the door that is common in most households with school-aged children. "We get up at our leisure - usually around 8:30," says Veronika. "We might visit a friend, or go to the library, and on Tuesdays we shop at the market. In summer, we spend most of our time outside and the girls entertain themselves a lot." New research due to be published this spring reveals a very different picture of Britain's home educators. "Out of 297 families, 184 said that they never use a timetable," says Mike Fortune-Wood of Home Education UK. "Ninety per cent never or rarely use textbooks, and nearly all said that happiness, contentment and self-fulfillment were more important than academic achievement. Only 15% felt that planning what to learn was important." So far, so good. But what, you might ask, are the children actually learning? "It wasn't important to me that the girls could read by a certain age, but they both picked it up for themselves at around seven," says Robinson. "Weighing cooking ingredients uses maths, and making a shopping list teaches them to write. Observing five hens has taught the girls about survival of the fittest. " But what about when the children grow up? Can they go to university? The home educators' answer is they can if they want to. There are a variety of routes into higher education, but probably the most common is to join a local college. This is what Gus Harris-Reid has done. "I was educated at home all my life. I'd never had a lesson or been inside a classroom until I started GCSEs," says the 18-year-old. "I'm now studying for 4 A-levels at Exeter College. I've had no problem with the work or with fitting in." When asked to reflect on his experience of home education, his considered response is, "Like a permanent holiday, really!" Not a bad start for someone who plans to take a mechanical engineering degree next year. According to the article, in homes with school-going children, _ .
Choices:
A. mornings are rushed and stressful.
B. the children hardly ever go outside.
C. the family wakes up around 8:30am.
D. the children must ask permission to go to the toilet. | A |

mmlu | Question:
In the six months that he'd worked at his aunt's shelter, Bryan had never grown close to a dog, but Patch was different. Aunt Kim had warned him, "Bryan, your mom says no dogs." The fact that Patch was deaf did not help. "It's not your fault you're deaf, "Bryan said, "Don't worry, because I've got a plan!" Later, Bryan got ready to leave. Making sure no one was coming; he secretly put the dog into his bag, and waved his aunt goodbye. Two hours after arriving home with Patch, Bryan sat sadly in his room. He had told his mother he would take care of Patch, but Mom didn't agree. Bryan lay awake that night, Patch jumped onto his bed, and soon he fell asleep. Unbearable barks woke Bryan sometime later. Bryan got up to quiet the dog, but he froze when he saw black smoke snaking into his room. He pulled the door open. Red-yellow flames licked greedily at the hallway entrance, blocking the front door. Suddenly, Patch ran down the hall. Bryan followed and found the dog in his sister Sarah's room. Bryan pushed Sarah to the window and shouted, "Jump with Patch!" Racing back into the smoky hallway, Bryan saw his mom. She seemed hardly able to catch her breath. Bryan tried to drag her to the hall window. But he failed. He looked up just in time to hear voices and feel _ pull them both to safety. A neighbor had heard Patch's barks and called 911. The firefighters thought a few candles had caused the fire. "I can't believe I forgot to blow out my candles," Mom said. "Sorry about the house, Mom,"Bryan said quietly. To his surprise, Mom smiled. It's OK. The important thing is that our family is safe. "She patted Patch's head. "Our whole family." Why couldn't Bryan fall asleep that night?

We spent a day in the country, picking wild flowers. With the car full of flowers we were going home. On our way back my wife noticed a cupboard outside a furniture shop. It was tall and narrow. "Buy it," my wife said at once. "We'll carry it home on the roof rack . I've always wanted one like that." What could I do? Ten minutes later I was PS20 poorer; and the cupboard was tied on the roof rack. It was six feet long and eighteen inches square, quite heavy too. In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea. After a time my wife said, "There's a long line of cars behind. Why don't they overtake, I wonder?" In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me. "Right, sir," he said."Do you need any more help?" I was a bit puzzled. "Thanks, officer," I said. "You have been very kind. I live just on the road." He was staring at our car, first at the flowers, then at the cupboard. "Well, well," he said, laughing. "It's a cupboard you've got there! We thought it was something else." My wife began to laugh. The truth hit me like a stone between the eyes. I smiled at the officer. " Yes, it's a cupboard, but thanks again."I drove home as fast as I could. What did the husband think of this matter?
Choices:
A. It was very strange.

mmlu | Question:
When you consider what subject to study in college, chances are that you and your parents will think about what you can make out of _ after graduation. You will likely ask the question: "Can I find a well-paid job or simply a job with a degree in this in the future?" This consideration also influences students when they come to choose between studying science or humanities at college. People generally believe that the humanities, which include literature , history, cultural studies and philosophy, do not prepare students for a specific vocation . Science subjects, however, are considered vocational courses that produce scientists, engineers and economists . "I've decided to take finance as my college major. My parents and I think this subject will help me get a good job or start a business," said Huachen Yueru, 17, a science student at Wuxi No. 1 High School. Even those who choose a liberal arts education often pick the humanities subject which they think will best help them later find a job. "I'm going to study Spanish in college, which I believe will open doors to a high-paying job for me," said Liu Chao, 18, a Senior 2 student at Dalian No 20 High School. He said few of his classmates show interest in subjects like philosophy and history, which are seen as "less promising" in job markets. The popularity of liberal arts subjects among college students has also been decreasing in the United States. American scholars and universities are concerned that in the ongoing economic crisis liberal arts subjects will be hit hardest. As money tightens , they worry that the humanities may become "a great luxury that many cannot afford", according to the New York Times. When you consider what to study in college, what does you and your parents usually think about ?
Choices:
A. whether you are interested in the subject.
B. if you can lead a happy life.
C. what you can make out of it after graduation.
D. How much you can learn in the college. | C |

For as long as they can remember Jynne Martin and April Surgent had both dreamed of going to Antarctica.This winter,they each made it to the icy continent as guests of the National Science Foundation(NSF).Bm they didn't go as scientists.Martin is a poet and Surgent is an artist.They went to Antarctica as participants.in the NSF's Artists and Writers program.The NSF is thegovernment agency that funds scientific research in Antarctica.But it also makes it possible for artists,including filmmakers and musicians,to experience Antarctica and contribute their own points of view to our understanding of the continent. The mixing of science and art in Antarctica isn't new.Some of the earliest explorersbrought along painters and photographers.Edward Wilson was a British painter,doctor,and bird expert who journeyed with RobertFalcon Soott on two separate Antamtic expeditionsmore than 100 years ago.Herbert Ponting was a photographer who also accompanied Scott on one of those expeditions.In hundreds of photos,Pontingcaptured the beauty of the continentand recorded the daily lives and heroic struggles of the explorers. Today's scientists write articles forscientificjournals.Unlike theearly explorers'journals,scientific papers can now be very difficult for non-scientists to understand.Writers in Antarctica workto explain the research to the public.Peter Rejcek is editor,writer,and photographer for the Antarctic Sun,an onlinemagazine devoted to news about the U.S.Antarctic Program.Rejeck began his career in the Antarctic in 2003 by spending a year at the South Pole.He has returned everyyear since,interviewing,scientists about research at Palmer,McMurdo,and South Pole stations. There are also scientists in Antarctica who work hardto explain their research to the public.Scientist Diane McKnight wrote The Lost Seal,a children's book that explains the research she and others are doing in an unusual ice-free area in Antarctica called the Dry Valleys. Antarctica is full of stories and wonders that are scientific,historic.and personal. People such as Martin,Surgent,Rejcek,and McKnight are devoted to bringing those storiesto asmany peopleare they can."Some people are going to be scientists,some people are goingto be journalists,some people are going to be artists,but we can all work together,'saysSurgent,"tocelebrate,thisextraordinary place." Why didn't some earliest explorers bring writers along?
Choices:
A. Writers were not funded at that time.
B. Writing can't capture the beauty of the continent.
C. Writers were not interested in popularizing science.
D. Early explorers'journals can be easily understood by the public. | D |
mmlu | Question:
Bringing up children is hard work, and you are often to blame for any bad behavior of your children. If so, Judith Rich Harris has good news for you. Parents, she argues, have no important long -term effects on the development of the personality of their children. Far more important are their playground friends and neighborhood. Ms. Harris takes to hitting the assumption, which has dominated developmental psychology for almost half a century. Ms. Harris's attack on the developmental psychologists' "nurture" argument looks likely to reinforce doubts that the profession was already having. If parents matter, why is it that two adopted children, brought up in the same home, are no more similar in personality than two adopted children brought up in separate homes? Or that a pair of identical twins, brought up in the same home, are no more alike than a pair of identical twins brought up in different homes? Difficult as it is to track the clear effects of parental upbringing, it may be harder to measure the exact influence of the peer group in childhood and adolescence. Ms. Harris points to how children from immigrant homes soon learn not to speak at school in the way their parents speak. But acquiring a language is surely a skill, rather than a characteristic of the sort developmental psychologists hunt for. Certainly it is different from growing up tensely or relaxed, or from learning to be honest or hard -working or generous. Easy though it may be to prove that parents have little impact on those qualities, it will be hard to prove that peers have vastly more. Moreover, mum and dad surely cannot be ignored completely. Young adults may, as Ms. Harris argues, be keen to appear like their peers. But even in those early years, parents have the power to open doors: they may choose the peers with whom their young associate, and pick that influential neighborhood. Moreover, most people suspect that they come to resemble their parents more in middle age. So the balance of influences is probably complicated. Even if it turns out that the genes they pass on and the friends their children play with matter as much as affection, discipline and good example, parents are not completely off the hook What does the author mean by saying parents are not completely off the look at the end of the passage?
Choices:
A. Parents should control the situation.
B. Parents should give their way to children.
C. Parents should spend more time on children.
D. Parents should take on their responsibility. | D |
mmlu | Question:
When it's five o'clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clock tells them they're done. These days, the time is everywhere: not just on clocks or watches, but on cell-phones and computers. That may be a bad thing, particularly at work. New research shows that clock-based work schedules hinder morale and creativity. Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 am to 10 a.m., research from 10 a.m. to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning. What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities--from project planning, holiday shopping, to yoga--by time or to-do list to measure how they performed under "clock time" vs "task time." They found clock timers to be more efficient but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up. The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture. Smart companies, they believe, will try to bake more task-based planning into their strategies. This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time. While most people will still probably need,and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier. What did Tamar Avnet and Anne-Laure Sellier find in their experiments about clock-timers?
Choices:
A. They seize opportunities as they come up.
B. They always get their work done in time.
C. They have more control over their lives.
D. They tend to be more productive. | D |
mmlu | Question:
Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world's largest floating ice sheet. The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America's National Science Foundation. "We chose a study site where, in the first year ,We went into the subglacial lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates ,and how the sediment underneath the ice sheet operates, as well, because it's the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean" says Ross Powell, who led the investigation. The team included scientists ,engineers, machinery and other supplies across the ice from the main U.S. scientific base at Mc Murdo Station to the researcher's camp .The camp was near a subglacial lake ,where an earlier study took place, Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels. "What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere." Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water ,sediment and other material from the grounding zone. Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area. Reed Scherer says the video images they saw in the Command Center were a total surprise. "It's a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive, Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active." This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating ice have on them? Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues. "We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past ,relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will he some differences that we'll see in the history of the ice sheet from the sediment cores, once we open them up ."But Ross Powell says the work raises more questions than it answers. What made the researchers surprised when they saw the video images?
Choices:
A. Researchers saw fish in the farthest south for the first time.
B. A video camera was able to work well under deep icy waters.
C. Sediment cores present differences in the history of the ice sheet.
D. The drill should dig down 740 meters to collect things. | A |
mmlu | Question:
School children are using mobile phone applications to do their homework, which seem to beincreasing during summer vacations. But instead of blaming students for their behavior, we should say noto too much homework. This is important because by using mobile phone applications to do theirhomework, students don't add much to their knowledge, says an article in Guangzhou-based YangchengEvening News. Excerpts : Using mobile phone applications to do homework is no different from copying from someone else'swork. This is the opinion of a vast majority of teachers. Students who seek cell phone apps help to do theirhomework will pay dearly during major exams when they cannot seek the help of such applications, theteachers say. The heavy load of homework Chinese students are burdened with, said to be the heaviest in the world,has led to the popularity of these applications. Senior high school students in China rarely go to bed before 11 pm. A report in Shanghai published in2013 showed that students in the city on average spend 28.2 hours in class every week, the 9th highestamong 65 countries and regions surveyed. Also, they spend an average of 13.8 hours a week doinghomework, most in the world. There is no association between the amount of homework one does and the amount of knowledge onegathers. In fact, a research by Australian experts shows that the result is exactly the opposite: the morehours students spend doing homework, the less effective they will be in gaining knowledge. The United States is one of the countries where students do little homework, but that has not damagedthe country's academic status in the world. So, it's time Chinese schools understood this fact and freed students of the unnecessary burden ofhomework. What's the writer's attitude toward the students' using mobile phone applications to do theirhomework?
Choices:
A. Supporting
B. Understanding
C. Scolding

mmlu | Question:
Before the early 1960's people interested in the differing roles of the left and right hemispheres of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the "dichotic listening" procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear. In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory signal: music. When right-handed people listen to melodic patterns they report them better from the left ear. according to the passage, right-handed people normally _ .
Choices:
A. have better hearing in their both ears

mmlu | Question:
If you know the following fact, you'll understand why many people suffer from foot problems. The average person walks the equivalent of three times around the Earth in a lifetime. That is enormous wear and tear on the 26 bones, 33 joints and more than 100 muscles that make up the foot. In a recent survey for the American Podiatric Medical Association, 53 percent of respondents reported foot pain so severe that it affected their daily function. On average, people develop pain in their 60s, but it can start as early as the 20s and 30s. And usually women give care to their feet while men don't. "A lot of people think foot pain is part of the aging process and accept it, and walk with pain," said Dr Andrew Shapiro. Though some foot problems are inevitable, their progress can be slowed. The following questions will help you assess whether you should take more preventive action as you age. Do you have flat feet or high arches ? Either puts feet at risk. Shoes that support the arch and heel can help flat feet. People with high arches should look for roomy shoes and softer padding to absorb the shock. Proper exercises also strengthen muscles, supporting the foot. Do your shoes fit? In the survey, more than 34 percent of men said they could not remember the last time their feet were measured. 20 percent of women said that once a week they wore shoes that hurt, and 8 percent wore painful shoes daily. Feet flatten and lengthen with age, so if you still stick to the shoe size you wore at the age of 21, get your feet measured. Do you walk? Putting more mileage on your feet is the best way to exercise the muscles and keep them healthy. Which of the following statements best explains foot pain?
Choices:
A. Not all of it can be avoided.
B. People can't slow its process.
C. Walking more will stop foot pain.
D. Preventive actions can't work well. | A |
mmlu | Question:
Is there intelligent life on other planets? For years, scientists said "no" or "We don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers. They believe intelligent life exists somewhere in the universe. They also think we will soon contact these beings. Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnet. The second reason is size--the universe is huge. "Tools like the Hubble telescope have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milk Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth." In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes allow scientists to discover smaller planets--the size of Mars or Earth in other solar systems. These planets might have intelligent life. Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signs. In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other." Why haven't beings from space visited us yet according to Shostak?
Choices:
A. They are afraid of us.
B. It's a long way away.
C. They don't want to see us.
D. They don't know how to use radio signs. | B |

Shopping on the Internet is becoming more and more popular. Why do people use the Internet to shop? Some people say it is more convenient. They don't have to leave their homes to order something; they can shop for anything they want at any time; they can find things for sale that they can't find in the Mores near their homes. Still other people say they can find better prices on the Internet. If you want to buy something on the Internet, you need a credit card. You have to type your credit card number and information on the website and send them to the store over the Internet. You have to be sure that the store will not use your information in the wrong way. You don't want someone to get your credit card number, so be careful with it, because people sometimes steal credit card numbers from stores. TV Internet is also a good place to go window-shopping. Window-shopping is when you look at the things for sale in a store, but don't plan to buy anything. In window-shopping you can see what kinds of things you are able to get and how much they cost. Some stores like Ross Stores have a website for information about their Mores, but not for shopping. Some stores have a website for information about their stores, and you can shop on line there, such as Office Depot, Payless Shoe Source and Safeway. Some stores like Amazone.com are only for on line shopping Which of the following is NOT true according to the passage?

Paula Radcliffe, chasing a third London marathon title , says she has become a stronger person after her terrible experience at the 2004 Athens Games. Radcliffe, who failed to complete the Olympic marathon and the 10,000m last August, said: "Athens made me a stronger person and it made me care less about criticism." "In the past I wanted to please everyone, but now I am going to listen even more to the people around me." She didn't care about criticism made at the weekend by Liz McColgan, who felt Radcliffe should have rested and let her body recover after her failure in Athens. "Liz is someone I look up to but she hasn't spoken to me since last year and if she really cared for me, I'm sure she would have contacted me." Instead Radcliffe won the New York City marathon just 11 weeks after Athens. "In New York I wasn't in my best state but I did know I was good enough to win the race." Radcliffe insisted her only goal in Sunday's race would be winning a third title and not chasing world records. However, Radcliffe has not ruled out in the future chasing her "final" world record time and questioned sayings that marathon runners have the ability in their career to produce only four or five world-class times. "I don't think that--although _ ," said Radcliffe. "That changes from person to person." Radcliffe is sure she can better her winning London 2003 performance at some point in the future. Following a successful three-month training period in the United States, the 31-year-old will chase a third title on Sunday after her first victory in 2002 and again 12 months later. Radcliffe clocked a time of 2:18:56 in her first 42.2-kilometer race three years ago. Afterwards she set a "mixed course" mark of 2:17:18 five months later in Chicago before lowering that to a time of 2:15:25 in the 2003 London event. Radcliffe's failure in Athens made her _ .

mmlu | Question:
I lost my left eye just after my first birthday -- I'd fallen seriously ill. My artificial eye was very convincing and I usually wore glasses over it -- even my boyfriend, Mick, didn't really notice. I told him I was blind in one eye just before we got married -- I was 19 at the time. He said he didn't care and that he loved me just the same. The day before we married, I was at my parents' house, when my other eye suddenly went blurry . My dad phoned the doctor, who told him it was probably nerves and I'd be fine by morning. He was right -- when I awoke, I was able to read my good luck cards. The wedding photographer arrived just as I was putting on my dress and I was called into the garden for a pre-ceremony photo. There was no time even to look in a mirror. Afterwards, we drove straight to the church. It was a sunny day, and as we approached I could see all our friends waiting. The service was delightful, and Mick and I went into the minister's office to sign the register -- the last thing I ever wrote with my sight. It was only when we reached the hotel, where the reception was taking place, that I started to feel strange. As we waited to greet our guests, my sight started to become blurry again and I really had to concentrate as our friends and family lined up to congratulate us. Afterwards, we went into the reception room, so the photographer could take our picture as we pretended to cut the cake. That's when the pain started. "Don't let anyone know!"my mum said. She'd always blamed herself for the loss of my other eye, wishing she'd taken me to the doctor earlier. Only a few family members had ever been told -- even my close friends had beennone the wiser. So even as the pain became more severe, I carried on as if nothing was happening. I'd waited so long for this day, and everyone seemed so happy, I didn't want to spoil things. I couldn't make anything out, but I managed tostay calm and made it through the meal and the speeches. I suppose it's normal for the bride and groom to stay close together after a wedding, and Mick led me around properly. We took regular dance lessons, so the first dance passed without incident, Mick leading me in a slow, graceful waltz. Afterwards, we left the building to see if a bit of air would improve the situation, but it didn't help, and nor did a lie-down. I still thought the blurriness would pass, as it had the night before. But I finally accepted that things just weren't going to get better on their own -- I was in so much pain. Mick sent for a doctor, who took one look at me and called for an ambulance. At the hospital, I remember a nurse bursting into tears when she saw me arrive -- I still had confetti in my hair. I was diagnosed with glaucoma, a disease in the eye that causes terrible pressure -- it was unrelated to the problems I'd had as a child, just a coincidence. An operation to try to save my sight seemed successful at first -- as the bandages were removed, I remember seeing a vase of flowers at the end of the bed. But it's the last thing I ever saw. It was hard, but I coped, and nearly 40 years on I feel I've had a full and active life. There are sights I'll always feel sad not to have seen -- the face of the daughter and my grandchildren. I'll always regret not finding the time to look in the mirror on the morning of my wedding, too -- despite everything that happened, I have happy memories of the ceremony. Why did the nurse at the hospital cry suddenly?
Choices:
A. Because she felt sad for the writer's experience.
B. Because she felt amazed at their happy marriage.
C. Because she was afraid of the writer's appearance.
D. Because she was moved by Mick's selfless love for the writer. | A |

Cassandra Feeley finds it hard to manage on her husband' s income. So this year she did something more than a hobby: She planted vegetables in her yard. For her fist garden, Ms Feeley has put in 15 tomato plants, and five rows of a variety of vegetables. The family' s old farm house has become a chicke n house, its residents arriving next month. Last year, Ms. Rita Gartin kept a small garden. This year she has made it much larger because, she said,"The cost of everything is going up and I was looking to lose a few pounds too; so it' s a win-win situation all around." They are among the growing number of Americans who, driven by higher living costs and a falling economy , have taken up vegetable gardening for the first time. Others have increased the size of their existing gardens. Seed companies and garden shops say that not since the 1970s has there been such an increase in interest in growing food at home. Now many gardens across the country have been sold out for several months. In Austin, Tex, some of the gardens have a three-year waiting list. George C. Ball Jr, owner of a company, said sales of vegetable seeds and plants are up by 40%, over last year, double the averag e growth of last five years. Mr. Ball argues that some of the reasons have been building for the last few years. The big one is striking rise in the cost of food like bread and milk, together with the increases in the price of fruit and vegetables. Food prices have increase of higher oil price. People are driving less, taking fewer vacations, so there more time to garden. Which of the following might be the best title for the text?

A. Family Food Planning
B. Banking on Gardening
C. A Belt-tightening Move
D. Gardening as a Hobby | B |
mmlu | Question:
America has been experiencing the longest economic increase in its history. Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings. But just a short walk from Manhattan's skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel. Brown is homeless----one of the 2.3 million people in the US who end up on the street. During the day, Brown collects aluminum cans and sells them for five cents a piece. At night, he sleeps on the street. "I have been on the street about eight or nine years, something like that," said the 62-year-old former construction worker. Brown admits he had problems with alcohol and has smoked cocaine. But he said he still wants a more stable housing arrangement. He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available. However, he sees no hope of finding affordable housing in New York. With the strong economy and unemployment down, beautiful housing is being built to meet demand. A US report shows rents in New York City rose more than 27 per cent, from $549 to $700 a month. One of the side effects of the strong economy is that rents have been going up. The majority of people who experience homelessness really just need some affordable housing help. But few housing companies are building for the poor. Many small apartments in the city now rent for $1,500 a month or more. Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her. She is angry about his drinking and won't allow it in her house. Smiling, he said he also has seven grandchildren whom he'd like to see more often. "All I've got to do is _ ," he said. It can be inferred from this passage that _ .

A. America is short of housing companies
B. the poor can't benefit from the increasing economy
C. poor people in America will become rich
D. housing companies will build more houses for the poor | B |
mmlu | Question:
I've often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes on and had genes off. In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only "reads" the part of this handbook it needs at any given moment. Can sleep affect how a gene reads instructions? It's a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours. Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less. Sleep restriction(six and a half to seven hours a night) changed 380 genes. Of these, 220 genes were down regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes . One of the most downgraded genes is that which has a role in controlling insulin and is linked to diabetes and insomnia . The most upgraded gene is linked to heart disease. So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little. The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes. What can we learn about Professor Derk-Jan Kijk's experiment?
Choices:
A. The experiment was carried out to find the answer to how genes affect sleep.
B. The experiment took a period of more than two weeks to reach a conclusion.
C. His volunteers were divided into two groups with two different sleeping patterns.
D. Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping. | C |

The unwanted disturbing of a mobile phone ringing at a critical moment has led to some famously strong reactions British actor Richard Grif-fiths,stopped a performance at the National Theatre and ordered The offending party to leave Judge Robert Restaino went considerably further.He was hearing a session of domestic violence offenders in a court when proceedings were interrupted by rings of a phone. "Everyone is going to jail unless I get that instrument now," he shouted. Over the next two hours,the judge entered a period of "incredible madness".He began by ordering the doors of the court locked,and set the officers to searching for the phone. When that failed to find the offending item he ordered each of the defendants present in the room up to his bench and in turn asked them if they had no idea, he sent each in turn to jail . All 46 of them. When a defendant protested the judge's actions were not fair to those who didn't possess the phone,Restaino replied:"I know it isn't.

Texting long messages can be a pain in the neck. The repetitive action of working your fingers across the keyboard of your cell phone can cause some of the same chronic pain problems previously limited to those who'd spent a lifetime typing. The possible connection is particularly worrying considering how much teens and young adults -- and increasingly those in professional settings -- are texting nowadays, said Judith Gold, who carried out one of the first studies on the potential connection. Text messaging is a fairly new technology, Gold says, so this is a new area of research for those who study ergonomics . But "considering the similarities in body position, findings from research on overuse injuries from computers could be applicable" to texting. "The way the body is positioned for texting - fixed shoulders and back with rapidly moving fingers - is similar to the position for typing on a computer," Gold explained. Previous research has found pain in the elbow connected with too much thumb texting. To look for a broader link between texting and chronic pain, Gold and her colleagues sent a questionnaire to 138 college students, asking them to report the number of text messages they sent per day (in four categories: 0, 1-10, 11-20, 21+ messages) and to point out any discomfort they felt on a body map. The research showed an association between the number of text messages sent per day and shoulder discomfort. The effect seemed to be particularly pronounced in males, though Gold says she doesn't know why that would be. "What we've seen so far is very similar to what we see with office workers who've spent most of their time at a computer," Gold said. However, Gold's study did not take account of the amount of time the people surveyed also spent typing on computers, which could be affecting the results. It can be inferred from the passage that _ .
Choices:
A. the study was the first one carried out by Gold
B. one positions oneself differently from computer-users when texting
C. the amount of computer-use time was calculated in the survey

It's parents' worst nightmare. Their child doesn't come home one evening and is missing for several days. When a 14-year-old boy from Atlanta, Georgia disappeared earlier this year, his mother turned to her Smartphone for clues using an app called Family Tracker that helped track his location. "You can see where your loved ones are without having to call or bother them. "said Roberto Franceschetti of LogSat, the creators of the Family Tracker, which has more than 100,000 users and is available worldwide. Parents can track the location of their child on a map, send messages, and even sound an alarm on the phone in a long distance. "We have an option for the sender to make a very unpleasant, noisy sound. It's a loud alarm and we repeat that sound every two minutes until the person picks it up, "he said. Parents don't need to own a Smartphone to track their children. The service is also accessible through the web, as long as the phone that is being tracked is running the app. Family Tracker has an additional service that keeps records of all data from the app for a two-week period, which the company calls GPS breadcrumbs. "With a subscription , we keep all the locations where people have been on our servers. You can see where your kid has been for the past two weeks. You can find out where someone was at a certain time or when that person was at a specific place, "Franceschetti explained. "When somebody gets abducted , usually whoever does this throws the phone away or takes the battery out. We were hoping that our app would at least provide information on where the person was abducted or where they had been in the past. " But will these types of apps let out personal secrets? "The advantages are huge compared to the disadvantages. Let's not forget that the person always has to give initial permission--no one can be tracked unless they allow someone to do it. "said Franceschetti. What can we infer from the passage?
Choices:
A. The app will enjoy a great popularity in the future.
B. The loss of children won't be a nightmare for parents any more.
C. The app will repeat the loud alarm continuously whenever parents track children.

There are stories about two US Presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK. We don't know if either story is true,but they are both interesting. The first explanation is based on the fact that President Jackson had very little education. In fact,he had difficulty reading and writing. When important papers came to Jackson,he tried to read them and then had his assistants explain what they said. If he approved of a paper, he would write "all correct" on it. The problem was that he didn't know how to spell. So what he really wrote was "ol korekt". After a while,he shortened that term to "OK". The second explanation is based on the place where President Van Buren was born,Kinderhook,New York. Van Buren's friends organized a club to help him become president. They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called "OK". According to the first story, the term "OK" _ .

When the six very best students from different cities in Guangdong Province all together chose universities in Hong Kong ; when the very best students of Beijing picked up HK University while giving up the nearby Peking or Tsinghua University ; when the highest enrollment rate of Hong Kong Science and Industry University reached 48:1, it's the high time to ask where the real education heaven for students in China is. Years ago, the answer certainly would be "Peking or Tsinghua University". But now no one could give the exact answer without hesitation . The only sure thing is that HK universities have gradually showed an unusual attraction to a great many mainland students. There's no doubt to call this HK craze , which is even out of the expectation of those HK universities themselves. How can HK universities shake the steady foundations of Peking and Tsinghua University and attract so many mainland students? First, Hong Kong universities offer large-amount scholarship, especially for the top students who can receive the scholarship as much as 400,000 HK dollars. Since higher education has become a kind of heavy burden of many families, it's easy to understand why the reaction to the generous offering of HK universities is great. Second, most HK universities receive professors and students from all over the world and carry out bilingual education. This kind of excellent language atmosphere is another attraction for mainland students. Furthermore, university students in Hong Kong have a better chance to study abroad as exchange students. Can mainland top universities like Peking or Tsinghua University be calm as before when facing the unexpected competition from HK? Will they take relevant measures to win back the top students who once help them set the worldwide reputation? Time will explain it . The fierce competition brought by HK universities can be a good thing for an entire improvement of education in China. After the awakening and action-taking of mainland universities , they can perform better together with HK universities. At least, it reminded the mainland universities the tuition fees are among students' top concern when they are choosing universities . It's time to move. From the passage we can see HK universities _ .
Choices:
A. didn't mean to enroll top students from mainland
B. didn't expect their enrollment of mainland students would be so popular
C. have strict enrollment rules and only 1 out of 48 students can get the chance to study there

mmlu | Question:
You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community. "How Yoga Can _ Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself. The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison. Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself. The reasons that yoga causes "serious injury", according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures. Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there. We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer. Which is not mentioned among the reasons for yoga being likely to cause injury?
Choices:
A. Teachers lack the knowledge of students' limits.
B. Modern lifestyle decreases our flexibility.
C. The body doesn't tell when you are in real pain.
D. Students themselves might not be in good physical condition. | C |

What is green food? Do you enjoy green food every day? The concept of "green food" was first suggested by the Department of the Ministry of Agriculture in 1990. Green symbolizes life, health and energy. Nowadays, people demand healthy and fresh food. Having enough food to eat is only a basic requirement, and they need more than this. They want to enjoy unpolluted, safe and nutritious food and eat comfortably. So the government does this through a set of "from the land to the dinner table" quality controls. It requires to change China's traditional agricultural structures and ensure the food of high quality. Safe vegetables refers to products without substances harmful to humans. Growing such vegetables requires no strong poisons, thus guaranteeing vegetables fresh and clean. There are strict regulations in place for even applying fertilizer . The examination of vegetables should reach the state food hygiene standard. The following conditions for green food are regulated by the China Green Food Development Center. Firstly, products or raw materials must reach the green ecological environment standard set by the Ministry of Agriculture. Secondly, crop planting, livestock raising, fish breeding and food processing must follow green food operating procedures set by the Ministry. Products must be up to the green food hygiene standard. External packing must be pasted with national standard universal labels, special green food packing decoration and tag regulations. However, by now, our goal hasn't been completely realized. When you return home with a full basket, you are still worried about whether what you have bought is green and healthy. Indeed, for the sake of our health, we still have a long way to go.

Did you ever think someone was scary because they looked different or ate strange food? Well, they might think the same about you!

Put yourself in their shoes.How would you feel? Putting yourself inside someone else's head can be a very powerful way to understand WHY they are acting the way they are. 3Try to make friends with people from other cultures!

mmlu | Question:
When discussing about friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share. When I was in the eighth grade, I had a friend. We were shy and "too serious" about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:" Let's start with a train whistle today." We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped. When I lived for a time in London, I had a friend. He was in despair and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted . We gave London to each other. For almost four years I have had a remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other's dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think: "Yes, I must tell...." We have never met. It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist , who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend. What is the best title for the passage?
Choices:
A. Unforgettable Experiences
B. Noble Companions
C. Remarkable Imagination
D. Lifelong Friendship | B |

In modern society, people can hardly do without mobile phone or computer. The youth of today are even more looking forward to Apple Corp's products. The iPad is an Apple tablet computer. The device sits somewhere between a laptop and a smart phone, according to Apple's chief executive, Steven P. Jobs, and does certain things better than both of them, like surfing the Web, reading e-books and playing videos. The iPad went on sale on April 3, 2010, and Apple said it had shipped 500,000 units in the first week. The handheld device puts Apple on a direct collision course with the Kindle from Amazon, which Mr. Jobs ever considered as pioneering the category. It is common knowledge that media companies hope the iPad will finally lead to available ways for them to charge for news, books and other materials. The half-inch thick, 1.5-pound device features a 9.7-inch multi-touch screen and is powered by a customized Apple microchip, which is called A4. It has been designed with an exposed screen and without a camera or separate keyboard. The iPad has the same operating system as the iPhone and also has access to its 140,000 applications. The price of the device starts at $499 for the most basic model, with a Wi-Fi wireless connection. More expensive models with more memory and with 3G wireless access will cost $629 to $829, depending on storage size. Because Apple is attempting to popularize a new kind of computing device, acceptance among consumers is expected to be slower than with previous Apple devices. Critics assume that some buyers are waiting for future versions of the iPad to appear, perhaps with a camera or USB ports . On its first day on sale, iPad users downloaded more than one million applications from the company's AppStore and more than 250,000 electronic books from its iBookstore. A new wave of apps is expected in response to the iPad. For an application developer, having an application accepted for a highly desired Apple product means reaching a passionate group of consumers. The potential income is huge: the apps market for the iPhone and iPod Touch alone is already worth a billion dollars a year in sales. It is implied in the passage that _ .
Choices:
A. people may download any application from the App Store
B. the Apple company will make more profit from the iPad
C. people would prefer to buy an iPad rather than an iPhone
D. owning an Apple product means that you will be respected | B |

mmlu | Question:
I was sure that I was to be killed. I became terribly nervous. I felt in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could hardly get it to my lips. But I had no matches, they had taken those. I looked through the bars at my jailer . He did not make eye contact with me. I called out to him "Have you got a light?" He looked at me and came over to light my cigarette. As he came close and lit the cigarette, his eyes absently locked with mine. At that moment, I smiled. I don't know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. Anyway, I smiled. I know he didn't want to, but my smile went through the bars and generated a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile. I kept smiling at him, now considering him as a person and not just a jailer. "Do you have kids?" he asked. "Yes, here, here." I took out my wallet and nervously felt the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes were filled with tears. I said that I was scared that I'd never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out and set me free. "My life was saved by a smile." Yes, the smile--the unaffected, unplanned, natural relation between people. I really believed that if that part of you and that part of me could recognize each other, we wouldn't be enemies. We couldn't have hate or scare. Which of the following do you agree with most?
Choices:
A. The jailer helped him because he was a friend of the writer.

A gadget which makes water out of air could become the greatest household invention since the microwave.http://www.ks5u.com/gaokao/beijing/ Using the same technology as a dehumidifier ,the Water Mill is able to create a ready supply of drinking water because it can always get from an unlimited source--the air.http://www.ks5u.com/gaokao/beijing/ The company behind the machine says not only does it offer an alternative to bottled water inhttp://www.ks5u.com/gaokao/beijing/ developed countries, but it is a solution for the millions who face a daily water shortage.http://www.ks5u.com/gaokao/beijing/ The machine works by drawing in wet air through a filter and over a cooling instrument which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights. Inventor Jonathan Ritchey said, "The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable." The machine, which is about 3 feet wide, is likely to cost PS800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly calculates that a liter of water costs around 20 pence to produce. Environmentalists state that half the world's population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking. The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won't be much of a problem. What does the passage lead us to believe?http://www.ks5u.com/gaokao/beijing/

Father was in the army all through the First World War, so up to the age of five, I never saw much of him, and what I saw did not worry me. Sometimes I woke and there was a big figure looking down at me. Sometimes in the early morning I heard the closing of the front door and the sound of shoes walking down. These were father's entrances and exits. Each time he went away, he left me lots of presents--model tanks, knives and all sorts of military equipment which he put in a long box. When he was not there, mother let me get a chair and search through his treasures. She did not seem to think so highly of them as he did. The war was the most peaceful period of my life. Every morning I awoke as soon as it was light and felt myself to be like the sun. Life never seemed so simple and clear and full of possibilities as then. I got up, went into mother's room and climbed into the big bed. She woke and I began to tell her of my plans. I talked but then fell asleep and woke again only when I heard her below in the kitchen, making the breakfast. I often wondered what mother and I should do all day and what present I would get for Christmas. There was that little problem of the baby, for example. Mother and I could never agree about that. Ours was the only house in the street without a new baby, and mother said we could not buy one until father came back from the war as they were very expensive. That showed how simple she was. The Geneys who lived nearby had a baby, and everybody knew that they had hardly any money at all.

One day, a farmer was walking along a road with his son Thomas. The father said, "Look! There's a horseshoe, pick it up and put it in your bag." Thomas said, "It isn't worth the trouble." His father said nothing but he picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the horseshoe and with the few pennies he bought some cherries . The father and the son continued their way. The sun was well up in the sky, and there wasn't a house or even a tree where they could have a rest. Thomas felt too thirsty to walk on. At this time, his father dropped a cherry on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another cherry and once again, his son lost no time in picking it up and putting it in his mouth. And so they went on. The old farmer dropped the cherries and the son picked them up. When Thomas had eaten up all the cherries, his father said to him, "My dear son, if you had bent down early to pick up that horseshoe, it would not have been necessary for you to bend so many times for the cherries. Always remember the lesson that he who does not worry about the little things will find that he cannot do the great things." The father dropped the cherries one by one, because _ .

I first came across the concept of pay-what-you-can cafes last summer in Boone, N.C., where I ate at F.A.R.M (Feed All Regardless of Means) Cafe. You can volunteer to earn your meal, pay the suggested price($10) or less, or you can overpay--paying it forward for a future customer's meal. My only regret after eating there was not having a chance to give my time. So as soon as Healthy World Cafe opened in York in April, I signed up for a volunteer shift . F.A.R.M and healthy World are part of a growing trend of community cafes. In 2003, Denise Cerreta opened the first in Salt Lake City. Cerreta now runs the One World Everybody Eats Foundation, helping others copy her pay-what-you can model. "I think the community cafe is truly a hand up, not a handout," Cerreta said. She acknowledged that soup kitchens have a place in society, but people typically don't feel good about going there. "One of the values of the community cafe is that we have another approach," she said. "Everyone eats here, no one needs to know whether you volunteered, overpaid or underpaid." The successful cafes not only address hunger and food insecurity but also become necessary parts of their neighborhood -- whether it's a place to learn skills or hear live music. Some teach cooking to seniors; some offer free used books. Eating or working there is a reminder that we are all in this world together. My 10 am-1pm shift at World-Healthy-Cafe began with the cafe manager -- one of the two paid staff members.

Choose the best answer (,) Suppose you are 17 and live alone with no money. Years ago, that was my dad. His father died when he was 10, and as the oldest of five, he had to take care of his brothers and sisters. When his mother remarried, my dad had to leave home. With few choices, he joined the army, and worked as hard as he could for a job, a nice house, and a family. Having a dad like him has made me different from other people; with his help and advice, I set and meet my goals. When I wanted to play basketball, my dad said, "Don't let anyone tell you what you can or can't do." People thought I was too small to play, but he let me know I could. Looking back now, I know why my dad said this to me: it was something his father and mother never told him. Time flew by. It was time for me to look for a job. A department store offered me a job as cart assistant. For the whole day, I pushed shopping carts. It was so cold that I couldn't move my hands. But my dad wouldn't let me give up, even though I wanted to. He kept saying it would get better, and he was right. I've worked there for a year now and I do much more than just push carts. My dad helped me grow into the person I'm becoming. When I was younger, I was small. The other boys called me " _ Nicky". I hated it. I went to my dad for a help. He encouraged me and helped me make an exercise plan and I got to work. In my life, there are different roads. My dad helped me get on the one I continue on today. I know I am just at the beginning. There will be difficulties. But there will always be my dad. Even when he is not physically here for me, his words won't leave my mind. At the age of _ , my father had to care for his brothers and sisters.

mmlu | Question:
How to improve our life? Many people think that they have to accept whatever life throws at them. They'll say, "This is my destiny .I cannot change it." Of course not! You don't have to suffer needlessly. Your life depends on you, not on any other external factor. I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, and then goes to sleep. Next day, the same routine cycle follows. Huh! Is this what she calls "doing her best"? She believes she has tried her best and just accepts it in her heart that this is the life that has been intended for her and that her luck can only change if God wills it. She hasn't realized that we have to do our share of making the effort to live the life of our dreams. Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone(unless it contributes to your success),and get your mind and body to work! Don't expect your luck to change, unless you do something about it. If something goes wrong, don't just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively; you also have to act positively. If someone's life is in trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don't just stand(or sit)there, do something to improve your life. The text is mainly written to advise you to _ .

mmlu | Question:
For years, business people in Western Europe were worried. They knew they could not compete against business from the U.S. The United States is much larger and had many more resources than any Western European countries. Some European people realized that the European nations need to join together to help each other. If they could forget their language differences and the differences in customs, they might become strong competition against other countries. In 1958, six of the European countries --- Belgium, the Netherlands, Luxembourg, France, Germany and Italy got together and decided to cooperate. They called their group the European Economic Community, or the Common Market. These countries agreed to join their resources together. Within a few years, the European Economic Community had worked so well that its members were more prosperous than many other European nations. Soon, other nations began to realize the advantage of the Common Market. Today the Common Market includes most of the important countries in Western Europe. It is helping Western Europe to again take its place as a leader among the industrial nations of the world. Which statement is true?

A. The Common Market is only a political association.
B. The Common Market is an economic and political association
C. The Common Market is only an economic association

Land Art, sometimes referred to as Earth Art or Earthworks, is a form of art which involves using physical landscapes to create art, taking art out of the museum and into the outside world. Modern Land Art movement really got going in the 1960s when American artists began creating Land Art on a large scale. Today, works of modern Land Art can be seen all over the world, sometimes right alongside much older pieces of Land Art created by people who lived thousands of years ago. Land Art, which is not necessarily unchangeable, can take a number of forms. For examples, in 1970 Robert Smithson created the Spiral Jetty , made of a collection of stones and mud, in the Great Salt Lake. The American artist made a large jetty in a spiral shape which sticks out into the waters of the lake. Reshaping the landscape is a common characteristic of Land Art, which can be created by moving parts around. People can also add things to the environment to create Land Art, like salt, which is added to the Spiral Jetty. It is possible to use plants. In all cases, Land Art is immovable. Land Art is designed to gradually form, change, and eventually decay . That's one of the biggest differences between Land Art and most of the art one sees in the museums. Some works of art can exist only for a few hours or days. Others are exposed to rain and wind so that they develop and decay over time, which is part of the attractiveness in the eyes of the artists. What is the passage mainly about?
Choices:
A. Works of Land Art.
B. History of Land Art.
C. Changes of Land Art.
D. Introduction of Land Art. | D |

Clean your ears, because airport security might soon be scanning them. According to a recent discovery, the shape of ears could provide a reliable new way of identifying people at airports. Researchers discovered that ears of each person have a unique shape and they have created a system that can scan them. The ear scanning technique uses a technology called image ray transform that highlights all the tubular structures of the ear and measures them. Professor Mark Nixon, a computer scientist who led the team from the University of Southampton, believes ear scanning could take place as passengers walk through security gates, for example, by placing cameras on either side to record an image of their ears. Comparing the results against a database of ear shapes, the new system could help airport security workers instantly identify passengers. Nixon and his team tested 252 images of different ears and found the system was able to match each ear to a separate image held in its database with 99 percent accuracy. Besides ear scanning, there have been other systems developed for identity recognition. "With facial recognition, the systems are often confused by crows feet and other signs of ageing," Nixon said. "Your ears, however, age very gracefully. They grow proportionally and your lobe gets a bit larger, but otherwise your ears are fully formed from birth." What's more, facial recognition software is often confused by changes in expression so people need to control their faces and in some cases even avoid wearing make-up. An ear scan system would also offer a less _ alternative toretina scanning, which requires passengers to stare at scanners from a close range. Fingertip detection has long been the most effective way of identifying someone. Nixon expects there to be a combination of different techniques that can be used at the same time to identify a person." The ear scanning system would help to find out _ .

A great way for teens to cool off during the summer is at water parks. If you live near a water park, you might think about getting a season pass. This way you can go as often as you like. Check to see if there are any water parks around you. Many are indoor facilities. So even if it isn't warm enough where you live to swim outdoors, you can enjoy swimming in a temperature controlled area. The prices are usually good. For example, one ticket to Water World, a water park, is only $5. Some teens like to get a part time job over the summer to make some pocket money. Older teens shouldn't have much trouble finding jobs. An idea is to get some teens together to form your own summer job business. You can walk dogs, bring in the newspapers, feed the cats, collect rubbish, water flowers, etc. Being that it's summer, many people go on vacation and could use someone to look after their houses while they're away. You can also think about other jobs you can do for them. Teens love freedom. Sure you would like to get to such places as the small, movie theaters, the zoo, the beach, picnic, bowling and local amusement park instead of staying home all summer. Then a summer bus pass will be helpful. Check to see if your area has one for you teens. Such a pass costs only $10 for the whole summer. The price is reasonable and also your parents don't have to always drive. If Sally goes to Water World with two friends, they should pay _ .

Are you in a bad mood? Don't worry! According to a new Australian study, a bad mood can actually be good for you. The study showed that being sad could help people to judge others more correctly and was also good for the memory. The study was carried out by Professor Joseph Forgas at the University of New South Wales."People in a bad mood paid more attention to the people and things around them than happy people .Happy people were more likely to believe anything they were told,"said Forgas For the study, Forgas and his team did a lot of experiments. During the experiments, they made the participants feel happy or sad by watching films and thinking about good or bad things of the past. In one of the experiments, happy and sad participants were asked to judge whether some wrong things were true or not. The results showed that people in a bad mood were less likely to believe that these things were true. People in a bad mood were also less likely to make mistakes when they were asked to remember the things that they saw. The study also showed that sad people were better at talking about their thoughts in written style. In fact, the study said that a slightly bad mood could help to make communication more successful. Which of the following is true according to the passage?

A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden and wait for it to flower . A biodegradable mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates . These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time." said one scientist. As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists. ,A, B, C, D,. (10) We can guess from the story _ .
Choices:
A. the new type of mobile phones is already on the market
B. the new type of mobile phones will sell very well
