mmlu | Question:
I was telling my boy Sonny the story of the hare and the tortoise . At the end I said, " Son, remember: Be slow and steady , and that will win the race. Don't you think there's something to learn from the tortoise?" Sonny opened his eyes wide, "Do you mean next time when I'm entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?" I was shocked, "But the tortoise didn't wish that the hare would fall asleep!" "He must have wished that," Sonny said, "Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did." "He didn't have such a wish," I insisted. "He won the race by perseverance , by pushing on steadily." Sonny thought a while. "That's a lie," he said. "He won it because he was lucky. If the hare hadn't happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he'd never have won the race. That's for sure." I gave up. Today's children are not like what we used to be. They're just hopeless. Sonny believed that the tortoise _ .
Choices:
A. won the race by his own hard working
B. took a risk by agreeing to run a race
C. was not given a fair chance in the race
D. in fact did win the race luckily | D |
mmlu | Question:
What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you. You say, "I wish I could help you but I'm short of money myself." In fact you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie? Professor Gerald Gullion of theprefix = st1 /UniversityofSouthern Californiahas made a scientific study of lying. According to him, women are better liars than men, particularly when telling a "white lie", such as a woman at a party telling another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liars hopes to profit or gain in some way. Research has also been done into the changes of people's behavior in a number of small, clearly unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying "I wish I were somewhere else now". They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The nose is very sensitive to such changes and the increased pressure makes it itch . Another gesture which gives away is what the writer Desmond Morris in his bookMan Watchingcalls "the mouth cover". He says there are several typical forms of this, such as covering part of the mouth with fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such a gesture can be understood, as an unconscious attempt on the part of the liar to stop himself or herself from lying. Of course, such gestures as rubbing the nose or covering the mouth, or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently in this situation. It is not one gesture alone that gives the liar away but a whole number of things, and in particular the context in which the lie is told. According to the passage, a "white lie" seems to be a lie _ .
Choices:
A. that other people have interest in
B. that other people cannot believe
C. told in order to avoid offending someone
D. told in order to take advantage of someone | C |
mmlu | Question:
prefix = st1 /NEW YORK--So we're going away on weekends and sticking close to home. But are we traveling with the kids? Here's how the down economy is changing the way we travel. SECONDARY CITIES Some smaller cities are stealing the glory . Fort Myers,Fla.experienced double digit growth in January 2009 over January 2008, based on American Express Travel bookings. Cities like Portland,Ore.are also becoming popular destinations, with Travelocity data showing an increase of 38% over last year. EvenPhiladelphia's star is rising, said Travelocity senior editor Shaw Brown. Brown said it's hard to explain exactly the reason for the _ : it could be a decrease in airfare or hotel prices or excellent marketing. Hotel rates inFort Myersare down about 10%. But hotel rates inPortlandare up, she said. She thinksPhiladelphia's higher popularity is due to good marketing, a decrease in airfare of 16% compared to the overall 8% decrease for domestic flights and more interest in historic destinations in general. FAMILY TRAVEL Rather than take a two-week vacation to Europe, families are going to national parks. David Mandt, spokesman for the Association of Amusement Parks, is cautiously optimistic about the summer season. He said even when gas was $4 a gallon in 2008, people continued to visit theme parks--they simply selected parks closer to their homes. While for years, park operators have used special offers, promotions and discounts to encourage families to visit at a specific time, the deals may be easier to find this year, especially when it comes to packages that include accommodations. Universal Orlando Resort has a deal allowing families to book a three-night package and receive two additional nights free. Packages include accommodations at a hotel near Universal and unlimited theme park admission to both Universal Studios and Islands of Adventure. It can be inferred from the news report that _ .

mmlu | Question:
CANYOUIMAGINEHOWHARDITWOULDBETOREADSENTENCESLIKETHIS? Every one of us gets so used to punctuation marks that not many of us give them a second thought. Actually, the ancient Greeks wrote this way. The lack of punctuation marks probably didn't bother good readers, though. As they read, they just put pauses where they fit best. Also at this time, sentences switched directions. A sentence read from left to right. The next one read right to left, and then left to right again, etc. The ancient Romans sometimes punctuated like this: They * put * something * that * can * separate * words * in * a * sentence. The word punctuation actually comes from this idea and the Latin word punctum, which means a dot. When the 5thcentury arrived, there were just two punctuation marks: spaces and points. The spaces separated words while the points showed pauses in reading. Then in the 13thcentury, a printer named Aldus Manutius tried to standardize punctuation. He always used a period for a complete stop at the end of a sentence. He used a slash (/) to indicate a short pause. Over time, that slash was shortened and curled, and it became the modern comma . Since that time, other marks have enlarged the punctuation family. The exclamation mark comes from the Latin word io. It means "exclamation of joy." The question mark originally started out as the Latin word questio, meaning question. Eventually, scholars put it at the end of a sentence to show a question. Punctuation even keeps changing nowadays. New marks are coming into existence, and old punctuation marks are used in new ways. Take for example the "interrobang". This 1962 invention combines the question mark and exclamation mark for times when writers want both. For example, "She did what?" or "How much did you pay for that dress?" Obviously, the interrobang is not widely used or recognized yet, but its invention shows that English is not yet finished with its punctuation. We can learn from the passage that _ .
Choices:
A. ancient Romans didn't use any punctuation marks
B. exclamation and question marks came from Latin
C. spaces and slashes were already used before the 5 thcentury
D. Aldus Manutius first started to use commas | B |

mmlu | Question:
How much pocket money do you get from your parents every month? Maybe 200 yuan? But for Li Beibei, 30 yuan each month is enough. The only thing she buys is lunch--1.5 yuan each day. "Meat is too expensive for me," said Li. Li, 14, is a Junior 1 student at Beijing's Xingzhi Experimental School. Her parents are migrant workers . They came to Beijing from a village in Luohe, He'nan two years ago. Her father now works as a cleaner and gets 500 yuan every month. Her mother has no job. Li Beibei has 460 friends at Xingzhi.

mmlu | Question:
The Production Department can be a fun place to work in a TV station. It can also be quite stressful if the station broadcasts a significant amount of live programming. There can be a number of interesting positions in this department. Here is a list of the core ones: The Production Manager heads the department, and is the person to contact if you are interested in working in this area. He or she oversees all activities in the studios, hires and fires workers, meets with customers who want to produce an advertisement, and monitors expense budgets for the department. The person in this position may also sometimes act as a Director, Producer, Camera Operator, or any other role in which they are proficient. Directors lead the crew during a production session. Over a headset, the Director tells Camera Operators what shots to get and the Technical Director (TD) what audio and video to put on the air. Directors work closely with the Producer of each program, ensuring that the final product meets with the Producer's demands. A Technical Director is a master at "punching" up the correct video source. In other words, if the Director calls for camera one, the Technical Director puts camera one on the air. The TD sits in front of a massive board called a "swicher" during production sessions, which allows him or her to literally switch between video sources. Since this can be a high-pressure, fast-moving job, the best Technical Directors are people who can stay even-tempered and in control. The Stage Manager is responsible for everything that goes on in the television studio. This person makes sure all of the equipment is in good working order, oversees the building and placement of all staging, and may even set the lighting for all productions. Really efficient Stage Managers take pride in their studios, and it would not be unusual to see this person sweeping the floor or cleaning the sets between productions. This is a leadership position, which often leads to promotion to the position of Production Manager. The Production Manager _ .

A. seldom takes part in producing programs
B. is also called "Producer"

mmlu | Question:
The best swimmers tend to be tall and thin with long arms, long legs, long feet, and long hands. The size of their hands gives them great "water grasp", and only a very small hand movement keeps them afloat. They also have great strength, endurance, insulation against heat loss while in water below body temperature, thus better energy conservation, low resistance when in the water, and swimming stroke mechanics . Part of the reason why some people are better swimmers than others has to do with body density. The average person's body density is slightly less than that of water. Muscle has greater density than fat. Therefore, very muscular people tend to be poor at staying afloat. Bone has greater density than fat. Therefore, very skinny people tend to be poor at staying afloat. Good buoyancy is not necessarily the most important factor in good swimming, but it certainly helps. For example, great competitive swimmers--tall, thin, and usually more muscular than average--tend to have greater body density than average and less buoyancy. Many would not float very well if they remained motionless in the water. Their much greater "water grasp" makes up for it. www.ks5u.com The average woman contains a higher proportion of fat in her body than the average man, and the average man contains a higher proportion of muscle in his body than the average woman. Therefore, in general, women are better floaters than men. Compared with other competitive sports, the performance of women is closer to that of men in competitive swimming. Buoyancy is important because_.
Choices:
A. it helps people to be safer in water
B. it can help people to swim better
C. it can never be trained to get better
D. it increases swimming length | B |

mmlu | Question:
Looking back on my childhood. I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic. Before Word War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects. I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people's observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together .This has resulted in my publishing 300 papers and books. Which some may light honor, with the title of scientific research. But curiosity a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist? One of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds. The author can't remember him relatives clearly because _
Choices:
A. He didn't live very long with them
B. He was too young when he lived with them.
C. The family was extremely large
D. He was fully occupied with observing nature. | D |

Having spent two and a half years in China over several visits, I don't remember ever going through a phase we in the United States call "cultural shock". This period of difficulty in adjusting to a new culture would probably have set in during my semester at Peking University. Of course, this is not to say that I didn't notice any differences between the American and Chinese cultures upon my arrival at Peking University, I did notice the differences. Looking back, I remember one of the first differences I noticed: Chinese universities are surrounded by walls. To an American, this is one of the most striking aspects of a Chinese university which immediately sets it apart from an American campus. Having grown up in the United States, I had never seen a university surrounded by high, cement walls. My idea of a university, based on having seen scores of them in different states of the U.S., was a place of life and learning, an inseparable part of the community in which it was located, open not only to the students of the school itself, but also fully accessible to students from other schools and to the broader public. My idea of a university was that it was a center of cultural life, a resource for the entire community. In all my twenty-one years, it had never occurred to me that a school would have a wall around it. Walls enclose and separate; schools expand and integrate . _ I asked a Chinese friend if all Chinese universities have walls around them. "You know, I have never really thought about it. I guess so. I guess all Chinese schools have walls around them, not just universities." "Why?" I asked, "What's the point?" "I don't know. To protect us, I suppose." "From whom?" "I don't know. Don't you have walls around your schools in the United States?" I thought carefully before answering. "No, I've never seen or heard of a university encircled by a wall." My Chinese friend seemed puzzled. Walls around schools came to strike me as more than just an architectural difference between the United States and China. As China continues to open up to the outside world, these walls seem increasingly out of place. The author felt strange about Chinese culture when he _ .
Choices:
A. studied in Peking University
B. talked with his friends about the walls
C. experienced the "cultural shock" at his arrival
D. spent two and a half years in China over several visits | A |

As I grew into a man, I often looked to my father for advice and support. There were many things about his character that I admired, but like any young boy, I often thought that my father's ideas were from the past and out of date. I did well as a student and was the first person in my family to graduate from university. I went on to be a university professor and writer, and most people would say that I have had a very successful life. But I know much of my success is because of the lessons that he passed onto me.

mmlu | Question:
When young people begin to live independently, home-hunting can bring some stress. But they would do well to remember that a new alternative is available--micro-home. Called "tiny houses", these houses have all living necessities in a small package, including kitchen, bedroom and bathroom. Generally under 50 square meters, most tiny houses accommodate just one or two people though some claim the space for more. What's lost in size is not lost in design as these homes are often quite unique and modern in design. Besides an attractive appearance, tiny houses can also have unique practical features. Making the best of urban space, the 72- to122-centimeter-wide Keret House in Warsaw, the world's narrowest home, fills in an alley. The Ecocapsule home uses solar power, wind power and rainwater collection to enable its owner to live practically anywhere. A system of rails allows the DALE micro-home to adjust room size and number as well as adding the option of an open or enclosed courtyard. Visually appealing as micro-homes are, there are a few drawbacks to consider before getting cozy on a mini-couch. Moving into a tiny house requires the removing of most non-essentials, regardless of the emotional connection to them. Guests will also mostly be out of the question as the limited space may even cause a solitary individual to experience some cabin fever . And finally, a micro-home is likely a temporary living option for most people since they will probably start families and acquiremore possessions. Though the limitations will scare some, there is usually a benefit. A small size results in a small price tag and small bills, making tiny houses easier to save up for and budget. And though you won't have much stuff around the house, this can provide the comfort of simple living and repairs. Micro-homes are also practically mobile and have eco-friendliness that can't be matched by other homes. They probably aren't for everyone or forever, but when it comes to your next (or first) home, they could be just what you need. Micro-homes are especially fit for _ .
Choices:
A. a young couple in hope of settling down permanently
B. an individual constantly suffering from cabin fever
C. a college graduate on a tight budget for the time being
D. a family of five in favor of environmental protection | C |

mmlu | Question:
According to figures released by the Office for National Statistics (ONS), the U.K. has about 7.7 million families with dependent children, of which 3.7 million have just one child, compared to 3 million with two and 1.1 million with three children or more. The number of families today with just one dependent child is now 47 percent and will likely rise to more than 50 percent in a decade. As the ONS confirms, "It appears that families are getting smaller." One obvious reason for this could be that women are putting off having children until they have established careers when they are bound to be less fertile. But it could just as well be a matter of choice. Parents must consider the rising cost of living, combined with economic uncertainty and an increasingly difficult job market. And this trend may continue growing as having an only child becomes more normal, which seems to be the mood on the mothers' online forum Mumsnet, where one member announced that she "just wanted to start a positive thread about how fab it is to have an only child". She had received 231 replies, overwhelmingly in the same upbeat spirit. Parents of only children insist there are plenty of benefits. Nicola Kelly, a writer and lecturer who grew up as an only child and is now a married mother of one, says her 15-year-old son seems more grown-up in many ways than his contemporaries. _ In a moving recent account journalist Janice Turner wrote about her own keenness to "squeeze out two sons just 22 months apart" as a reaction to her only-child upbringing. She was placed on a pedestal by her doting parents, whom she punished with a "brattish, wilful" rejection of everything they stood for. Desperate for a close friend she was repeatedly shattered by rejection and refers to her childhood as being "misery". Writer and clinician Dr. Dorothy Rowe, a member of the British Psychological Society, says that we all interpret events in our own individual way and there are some children who no matter what their circumstances feel slighted, while other children see the advantages of their situation. However, the one part of life that is unlikely to get any easier for only children is when they grow up and find themselves looking after their own parents as they become older. From what Dr. Dorothy Rowe said, we know that _ .
Choices:
A. journalist Janice Turner experienced a miserable childhood
B. she has a positive attitude towards Janice Turner's reaction
C. it's necessary for us to look at the event from our own angle
D. some are unable to make an objective assessment of their conditions | D |

Modality City has had a severe traffic problem on its streets. As a result, it enacted an ordinance prohibiting all sales to the public of food or other items by persons selling directly from trucks, cars, or other vehicles located on city streets. The ordinance included an inseverable grandfather provision exempting from its prohibition vendors who, for 20 years or more, have continuously sold food or other items from such vehicles located on the streets of Modality City. Northwind Ice Cream, a retail vendor of ice cream products, qualifies for this exemption and is the only food vendor that does. Yuppee Yogurt is a business similar to Northwind, but Yuppee has been selling to the public directly from trucks located on the streets of Modality City only for the past ten years. Yuppee filed suit in an appropriate federal district court to enjoin enforcement of this ordinance on the ground that it denies Yuppee the equal protection of the laws. In this case, the court will probably rule that the ordinance is
Choices:
A. constitutional, because it is narrowly tailored to implement the city's compelling interest in reducing traffic congestion and, therefore, satisfies the strict scrutiny test applicable to such cases.
B. constitutional, because its validity is governed by the rational basis test, and the courts consistently defer to economic choices embodied in such legislation if they are even plausibly justifiable.
C. unconstitutional, because the nexus between the legitimate purpose of the ordinance and the conduct it prohibits is so tenuous and its provisions are so underinclusive that the ordinance fails to satisfy the substantial relationship test applicable to such cases.
D. unconstitutional, because economic benefits or burdens imposed by legislatures on the basis of grandfather provisions have consistently been declared invalid by courts as per se violations of the equal protection clause of the Fourteenth Amendment. | B |

Summer time is a great opportunity for kids to learn how to work and earn a little bit of spending money. If your child needs a summer job, here are a few options to consider: Lemonade/Cookie Stand Benefits Creates a concept of running a business: Your child will be his own boss, set his own price , and run the show. It's a great introduction to running his own business. Limited Start-Up Costs: The things used to make lemonade are cheap, so your child should be able to get back his investment with a handful of sales. What Kids Learn About Money: Your child will learn a very valuable lesson about pricing. The price of his lemonade will decide how much he can sell, if he will recover his investment and the amount of profit. Yard Work Benefits: Repeated Customers: If a homeowner needs help raking this year, he'll probably want help again next year. Your child should be able to maintain a regular set of customers after one season. Safety: Yard work is generally safer than a lawn-mowing job. Without having to operate machines, your child will be much safer. What Kids Learn About Money: Because of the variability in pay, your child will need to learn how to negotiate a fair price with homeowners if they ask.

mmlu | Question:
Papa's Straw Hat Papa was a ranger. He worked with horses. He always wore clean clothes with a hat even when he worked. His hat was always the same kind of a cowboy hat- large black hat of heavy wool. He wore his hat full and high. I think he wanted to look taller than he really was. Mama was proud of the way he looked when he wore his hat and his best clothes. But in some way she got the idea that papa would lose his hair if he kept wearing a heavy wool cowboy hat in the hot weather. She began to talk about his hats. "Papa," she said one day, "why don't you get a nice cool straw hat? That heavy wool cowboy hat may cause losing hair!" Papa laughed at her and explained that the horses wouldn't recognize him if he changed the hat. But she didn't believe him. Mama talked and talked about the hat all summer long. At last papa answered, a little angry, "It would not the cowboy hat but a wife's talking about the hat that makes me lose my hair." Mama had a very serious look on her face. She went straight out and later came home with a straw hat. It was a bad year for ranger and we didn't have much money. She thought that if she spent the money for a straw hat, papa would wear it. When papa saw the hat, his face got red. Without a word, he pulled the straw hat down over his head until it hid his eyes and went on to train the horses. He was a good ranger and gentle to his horses. But as papa got close to the horses this time, they jumped high into the air, raising their front feet. All of them ran around in the rounded field and then raced toward the barn. Papa began to shout "Woo boys. Steady boys, steady." But there was nothing equal to. Papa walked back straight to the stove in the kitchen, pushed the straw hat deep down into the fire then turned to mama, in a way that even frightened me. "Now listen to me, mama. Understand this I will never wear a straw hat or any other kind of hat my horses do not like." Then he put on his wool cowboy hat and walked out of the house. I never heard mama talk any more about hats. Perhaps, that is why when papa died many years later, there was a round spot on the top of his head where there was no hair. According to the passage, a ranger is _ .

Every day when Cora Castle, 14, from Indiana, US goes back home, she opens her computer and logs into a website called Fuel Up to Play 60. She puts on what she has eaten and what kind of activities she has played that day. Then the site decides whether Castle has eaten healthily and done enough exercise. All the seventh graders in Castle's school have done the same thing since the year started. It's part of their health class. If the site finds her habits are unhealthy, it will give her advice. If she does something good, the website will give her a star. Her health teacher set up a competition to see which student could get the most stars from the website. Castle has got 30 stars so far. Cameron Bartlett said she liked tracking the food and activities. "This is the first year we've done it," she said. "It's really interesting to see all of the different choices that we have." The seventh grade health class is coming to an end. They won't be in health class, but the students all said that they would go on to take part in the Fuel Up to Play 60.

mmlu | Question:
It has been known that the octopus has many special skills, such as using hard shells for mobile homes and protection, disabling their suckers, plotting escapes, and even predicting World Cup soccer game outcomes. Can't we say it is a mysterious creature? While all these talents are impressive, they pale compared to its ability to "disappear" from plain sight. Researchers have long known that this is possible because of the presence of the organs under their skin, which expand or contract to produce a series of color1s, patterns and even skin textures in just milliseconds. Scientists had always believed that such a reaction was directed by a signal from the octopus's large, human-like eyes or brain. But a recent report published in the Journal of Experimental Biology by researchers from the University of California at Santa Barbara, indicate that the animal does not have to wait for a signal from its eyes or brain. It can "see" the light with its skin! UCSB doctoral student Desmond and Professor Todd said they have seen reports about octopus skin changing color1s in response to light with no signal from the eye or brain. However, there had been no follow-up to find out why this was the case and the two decided to see what they could uncover. They began by taking skin samples from a couple of California octopuses and exposing them to color1s, ranging from violent to orange and found that their skin is equipped with the same light-sensitive protein as is found in the cells in the retina of the eyes. Thanks to these proteins, the octopus can "see" the light and react without having to wait for a signal from the eyes or brain, thus enabling it to begin the escape process. Another research by University of Maryland researchers discovered that cuttlefish and squid share the same talent. Thanks to these findings researchers now know that their skin color1 can be controlled by both. What is still not clear is how the two come together to manage the whole process. The doctoral student plans to get to the bottom of the mystery. What is the next aim of Desmond on octopuses?
Choices:
A. Whether octopuses and cuttlefish have the same ancestor.
B. How the signals from their brain work with the proteins.
C. When the two teams will cooperate on their research.

Towards evening, Jennifer was walking on the beach with a gentle breeze blowing through her hair. Looking up at the golden red sun ball, she was surprised by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky. The atmosphere relaxed her. This was what she needed. "It's getting late," she thought, "I must go home. My parents will be wondering where I am." She wondered how her parents would react when she got home after the three days she was missing. She kept on walking, directing herself to bungalow 163, where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters, she would have been safe in her house. It was really getting dark now. She wished she had her favorite coat on. It might keep her really warm. She imagined having it with her. This thought dissipated when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... She entered the house. First, she went into the kitchen and saw a note written by her father, "Dear Ellen, there's some coffee ready; I went looking." But where was Ellen? On the right side of the hallway was her parents' room. She went in and saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn't slept for days. She was really pale. Jennifer would have wanted to wake her up, but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up something was different. She wasn't in her mother's room and she wasn't wearing the old clothes she ran away in. She was in her cozy bed in her pajamas . It felt so good being back home. Suddenly she heard a voice.

In some parts of the United States, farming is easy. But farming has always been difficult in the northeastern corner of the country, which is called New England. New England has many trees and thin, rocky soil. Anyone who has wanted to start a new farm there has had to work very hard. The first job has been cutting down trees. The next job has been digging the stumps of the trees out of the soil. Then the farmer has had the difficult job of removing stones from his land. This work of removing stones never really ends, because every winter more stones appear. They come up through the thin soil from the rocks below. Farmers have to keep removing stones from the fields. Even today, farms which have been worked on for 200 years keep producing more stones. That is why stone walls are used instead of fences around New England fields. The stone walls are not high; a man can easily climb over them. But they keep the farmer's cows from joining his neighbor's cows. In New England, stone walls are used _ .

Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door. They believe the 220- kilogram brown bear probably learned the trick while nudging a door to get it to open. Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick. The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door. ''We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time." Mum Nevenka Loknar told a reporter from a local newspaper. "I opened the door and saw him standing there and I didn't believe my eyes at first, then I ran for it as he walked in as if _ was the most normal- thing in the world." Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door. Mum Nevenka Loknar said, "The bear is so intelligent. It's incredible. We've tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn't be surprised if he knew how to use wire cutters." It is _ in Gerovo that a bear knocks at the door.

I came to the USA because I needed to study English here. I went to an English language school. I was not a beginner, but I was not good at English. At the end of the first term, I could read, write and speak, and I thought I was good at them. However, I was not good at understanding when people spoke to me. My teacher said," Why don't you repeat the classes?" I was not happy. I made progress every month, so I did not want to repeat them. However, it was true -- I was not good at understanding when people spoke to me. My teacher said, "Repeating the classes is a good way to practice listening. And if you repeat them, you will understand more spoken English." In the end, I repeated the classes. In the second term, I studied the same books that I did in the first term. My teacher was right. It was a good idea. Now, after studying English for a year, I can understand more spoken English. And I know that reading, writing and speaking are not enough; listening is also very important.

A wood fire can be handy when you ' re camping. You can roast marshmallows or stay warm, for example. Forest fires that rage out of control, however, are a big problem. Wildfires cause hundreds of millions of dollars in damage every year. And the amount of destruction has grown over the last 2 decades,especially in the western United States. To understand better why the northern Rocky Mountains region has been hit especially hard by wildfires, scientists from the University of Arizona in Tucson looked at weather, snow, and fire records from 1970 to 2003. Their study showed that, between 1987 and 2003, fires burned an area 6. 5 times larger than the area burned between 1970 and 1986. The fire season also started earlier-, and its average length increased by 78 days. Warmer spring and summer temperatures appear to be part of the explanation for this change. The average temperature in the study's more recent period was 0.871 higher than it was in the earlier period. And this trend is likely to continue. Experts predict that average summer temperatures may rise between 23/4 and 53/4 by the year 2050 in western North America. Hie timing of snowmelt appears to be another cause of the fire boom. When snow melts early in the season,forests become drier through the summer and catch fire and burn more easily. Western snow packs now typically melt a week to a month earlier than they did 50 years ago, according to recent studies. Some people have blamed the growing fire risk on policies that allow bush and branches to build up on forest floors. But clearing bush by itself won' t help much if changes in climate are largely responsible for increasingly severe forest fires. Scientists fix>m the University of Arizona found out the following EXCEPT _

Americans who volunteer for the Peace Corps get a chance to help improve lives in developing countries. They also get a chance to learn more about the world, and about themselves. This week this program is celebrating its 50th anniversary . President John Kennedy set up the Peace Corps soon after he took office in 1961. It was the time of the Cold War between the United States and the Soviet Union . The new program gave Americans a chance to answer the call to service that the president made in his inaugural speech. "Ask not what your country can do for you," he said. "Ask what you can do for your country." Kennedy told Peace Corps volunteers that America's image in the countries where they were going would depend largely on them. On August 30th, 1961, the first group of 51 Peace Corps volunteers arrived in Accra, Ghana, to serve as teachers. They had agreed to work for almost no pay. They would spend two years in Ghana helping its people and learning the reality of life in a developing country. Most of the volunteers had just completed college. About half of them taught English or health care. In the 50 years since then, more than 200,000 Americans have served as Peace Corps volunteers. They have worked in 139 countries. The Peace Corps is a government agency that was created to promote world peace and friendship. There are three goals: First, to help the people of interested countries in meeting their need for trained men and women. Second, to help promote a better understanding of Americans on the part of the people served. And, third, to help promote a better understanding of other people on the part of Americans. Today, the Peace Corps has more than 8,000 volunteers and trainees in 77 countries. They work in agriculture, economic development, education, the environment and health care. Some work in programs related to youth development. Fifty percent of current Peace Corps volunteers are women. The average age of a volunteer is 28. But the ages of Peace Corps volunteers range from 18 to 86. Some Americans join the Peace Corps after they retire . Today seven percent of volunteers are over the age of 50. And 19 percent are members of minority groups. Volunteers for the Peace Corps can _ .

BEIJING--Family planning officers will handle the illegal birth case of film director Zhang Yimou by following legal procedures, a government spokesman said on Tuesday, December 10, 2013. When asked to comment on Zhang's case at a press conference, Yao Hongwen, spokesman for the National Health and Family Planning Commission(NHFPC), said "Every citizen is equal before the law and nobody is allowed to have privileges to give birth to more children than allowed." Yao's comment came after media stories claimed that Zhang had remarried and fathered a total of seven children: one with his former wife, three with his present wife, Chen Ting, and another three from two lovers. "The NHFPC's attitude towards citizens' birth violations is consistent and clear...Every Chinese citizen should obey and safeguard the seriousness of laws and regulations." NHFPC spokesman Yao Hongwen said. China's family planning policy, introduced in the late 1970s to slow down the country's growing population, limits most urban couples to one child and most rural couples to two. The policy was recently relaxed, allowing couples to have two children if one of them is an only child. Those who break the policy face severe fines. The amount of the fine is generally several times the yearly annual income of the two spouses . Some media calculations put the fine that Zhang may face at as much as 160 million yuan(over $26 million). Zhang's birth case has caused criticism online about famous people who have more children than the policy allows. In an open letter on December 1, Zhang admitted that the couple has two sons and daughter and they are willing to accept investigation and punishment according to China's laws and regulations. He apologized to the public. However, the letter denied that Zhang had lovers and was father to as many as seven children from various mothers. Zhang, one of the "fifth generation" of Chinese filmmakers, made his first directorial work in 1987 with "Red Sorghum" and has won a number of award worldwide. He was chief director of the opening and closing ceremonies of the Beijing Olympic Games. The purpose of the news report is to _

mmlu | Question:
Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee. U.S. biochemist Ben Yu has created 'Sprayable Energy,' which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee. Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure. Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: 'The reason for this is our product not being ingested, isn't almost entirely metabolised by the liver before entering your system and becoming available to your body.''Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee. Sprayable Energy`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day. It claims that after spraying the product on the skin, users will feel 'awake and focused without being over-stimulated', which is common with coffee and energy drinks. We can conclude from the passage that _
Choices:
A. Sprayable Energy can not be permitted to be used by people now.
B. Sprayable Energy has not already gone into mass production
C. Each spritz of Sprayable Energy has the same effect as a full cup of coffee
D. Sprayable Energy is well received by flagging workers. | B |

The Future of Technology William, a businessman, arrives in a foreign airport. He doesn't show his passport. Instead, a machine in the wall reads the computer chip in his arm. This contains information about him: his name, age, and I.D number. He exits the airport, and a car door opens when it "sees" him. The car takes him to his hotel. His room "knows" he has entered the building and it "reads" his body. He is cold, so the room becomes warmer. William then watches a business presentation on a video wall. When he takes a bath, the presentation "follows him and continues on the bathroom wall. Finally, the room plays music to help him sleep. It turns off the music when it "sees" him sleeping.

mmlu | Question:
I try not to be biased but I had my doubts about hiring Stevie. His social worker assured me that he would be a good, reliable busboy. But I had never had a mentally handicapped employee. He was short, a little fat, with the smooth facial features and thick-togued speech of Down's Syndrome . I thought most of my customers would be uncomfortable around Stevie, so I closely watched him for the first few weeks. I shouldn't have worried. After the first week, Stevie had my staff wrapped around his stubby little finger, and within a month my regular trucker customers had adopted him as their official truck stop mascot. After that, I really didn't care what the rest of the customers thought of him. He was like a 21-year-old in blue jeans and Nikes, eager to laugh and eager to please, but fierce in his attention to his duties. Every salt and pepper shaker was exactly in its place, not a bread crumb or coffee spill was visible when Stevie got done with the table. Our only problem was persuading him to wait to clean a table until after the customers were finished. Over time, we learned that he lived with his mother, a widow who was disabled. Money was tight, and _ . That's why the restaurant was a gloomy place that morning last August, the first morning in three years that Stevie missed work. He was at the Mayo Clinic in Rochester getting a heart surgery. His social worker said that people with Downs Syndrome often had heart problems at an early age and there was a good chance he would come through the surgery in good shape and be back at work in a few months. A ripple of excitement ran through the staff later that morning when word came that he was out of surgery, in recovery, and doing fine. Frannie, my head waitress, did a little dance when she heard the good news. Belle Ringer, one of our regular trucker customers, stared at her and asked, "Okay, Frannie, what was that all about?" "We just got word that Stevie is out of surgery and going to be okay." "I was wondering where he was. I had a new joke to tell him. What was the surgery about?" Frannie quickly told Belle Ringer and the other two drivers sitting at his booth about Stevie's surgery, then sighed: "Yeah, I'm glad he is going to be OK," she said. "But I don't know how he and his Mom are going to handle all the bills. From what I hear, they're barely getting by as it is." Belle Ringer nodded thoughtfully, and Frannie hurried off to wait on the rest of her tables. After the morning rush, Frannie walked into my office. She had a couple of paper napkins in her hand. "What's up?" I asked. "I cleared off that table where Belle Ringer and his friends were sitting after they left, and I found this. This was folded and tucked under a coffee cup." She handed the napkin to me, and three $20 bills fell onto my desk when I opened it. On the outside, in big, bold letters, was printed "Something For Stevie". That was three months ago. Today is New Year's day , the first day Stevie is supposed to be back to work. His placement worker said he had been counting the days until the doctor said he could work, I arranged to have his mother bring him to work, met them in the parking lot and invited them both to celebrate his day back. I took him and his mother by their arms. "To celebrate you coming back, breakfast for you and your mother is on me." I led them toward a large corner booth. I could feel and hear truck customers and the rest of the staff following behind as we marched through the dining room. We stopped in front of the big table. Its surface was covered with coffee cups and dinner plates, all sitting slightly on dozens of folded paper napkins. "First thing you have to do, Stevie, is clean up this mess," I said. Stevie looked at me, and then pulled out one of the napkins. It had "Something for Stevie" printed on the outside. As he picked it up, two $10 bills fell onto the table. Stevie stared at the money, then at all the napkins peeking from beneath the tableware, each with his name printed on it. I turned to his mother. "There's more than $10,000 in cash and checks on that table, all from truckers and trucking companies that heard about your problems. Happy Thanksgiving!" While everybody else was busy shaking hands and hugging each other, Stevie, with a big, big smile on his face, was busy clearing all the cups and dishes from the table. What made the author not fully satisfied with Stevie's work?
Choices:
A. That he made customers uncomfortable.
B. That he couldn't pay attention to his duties.
C. That he often spilled cups of coffee.
D. That he usually cleaned the table too early. | D |
mmlu | Question:
Hiking is an outdoor activity which consists of walking in natural environments, often in mountainous or other scenic terrain . People often hike on hiking trails. It is such a popular activity that there are numerous hiking organizations worldwide. It is considered one of the recreational activities. Many people say they go hiking because they love to walk outdoor, without necessarily having a destination ahead of them. This makes hiking much more different than walking down the street to the store or to some other places that we need to go. People who like hiking say, "We enjoy ourselves along the way whether we arrive somewhere important or not." Some people add another reason for hiking to the basic one of loving to be outdoors. These folks see hiking as not only mentally healthy for clearing the mind but also physically healthy as great exercise for the body. Unlike some other exercise programs, hiking can be an activity for almost anyone in reasonably good health. Hiking on a smooth, level path is even good exercise. Trudging over rougher terrain can be a workout and a time of enjoyment at the same time. Some people who hike on a regular basis give little thought to the exercise part of the activity. These people are more likely to go hiking because they are exploring nature. They may be interested in the trees or the rocks. Perhaps they are interested in looking at the birds or the various animals that lodge in the forest or the park. Certainly park land is ideal for hiking. Many of these sites have marked for hiking. This leads many to take part in hiking specifically for the exercise and enjoyment of being outdoors, when they may not do this otherwise. Some people look at hiking as having two major benefits. When asked why they go hiking in their spare time many people will combine these reasons: It helps me relax; it doesn't take a great investment of money for equipment. For them, a good pair of shoes and some comfortable clothes can help them get away from work or other stressful situations that may arise in life. In many cases, these hikers can enjoy their favorite pastime all year long. They may be able to take those outdoor walks in almost any weather. It's safe to say that hiking can heal and please the human being in many ways. What is the text mainly about?

mmlu | Question:
Once upon a time, there was a farmer in central China. He didn't have money, so instead of a tractor , he used an old horse to plow his field . One afternoon, while working in the field, the horse fell down, dead. Everyone in the village said, "Oh, what a horrible thing!" The farmer said simply, "We'll see." He was so peaceful and so calm that everyone in the village got together and, admiring his attitude, gave him a new horse as a gift. Everyone's reaction now was, "What a lucky man!" And the farmer said, "We'll see." A couple of days later, the new horse jumped over a fence and ran away. Everyone in the village shook their heads and said, "What a poor fellow!" The farmer smiled and said, "We'll see." Eventually, the horse found his way home, and everyone said, "What a fortunate man!" The farmer said, "We'll see." Later in the year, the farmer's young boy went out riding the horse and fell and broke his leg. Everyone in the village said, "What a poor boy!" The farmer said, "We'll see." Two days later, the army came into the village to draft new recruits .When they saw the farmer's son had a broken leg, they decided not to recruit him. Everyone said, "What a fortunate young man!"

mmlu | Question:
As millions of playthings are recalled, doctors are reminded that the risks of lead exposure continue for young patients. Lead is such a well-known health - perhaps even contributing to the fall of the Roman Empire- that it came as a shock to discover that toys played by children could contain lead. Doctors are now dealing with the aftershocks. Just how dangerous is this exposure? That's the question physicians are being asked by parents who find a lead-polluted Elmo, of Dora. Millions of others toys, lunch boxes and pieces of jewelry manufactured in China have been recalled because they contain lead either in the paint that coats them or as a component of the plastic used to make the item more flexible. The lead content in some of the toys recalled this summer was 180 times the amount allowed by law. Some pieces of jewelry were almost 100% lead. Experts advise that the items do cause a risk and that doctors should urge parents to check the comprehensive lists of recalled products on the Consumer Product Safety Commission's Web site and return any appearing on those lists to the manufacturers. If exposure is suspected, a blood test is in order . Since there is no safe level of this universal element, the risk face by children for lead poisoning and its accompanying threat of learning disabilities and behavior problems is considerable. Doctors who have toys in their waiting rooms also are advised to see if any of them have been recalled and to check for chipped, flaking paint-even on those that haven't yet been recalled--since new announcements of toy risk continue. From the report we can infer that _ .
Choices:
A. children who are exposed to lead have learning disabilities
B. the unsafe toys have all been listed on the website
C. lead is used mainly to make the products flexible
D. some toy and jewelry manufacturers will suffer heavy losses | D |

Watercolor is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water. Fresco , one of the greatest of all art forms, is done with watercolor. It is created by mixing paints and water and applying these to wet plaster . Of the thousands of people who stand under Michelangelo's heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolor painting in the world. The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolor was used mainly for doing sketches or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have a widely-known love for the outdoors and also small, private pictures. The softness of watercolor had a remarkably strong attraction for them. The popularity of watercolor continued to grow until in the twentieth century. The United States passed England as the center for watercolor, producing such well-known watercolor artists as Thomas Eakins and Andrew Wyeth. The first watercolor artists were _ .

mmlu | Question:
Below is a selection from a popular science book. If blood is red, why are veins blue? Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? This question depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Do old people shrink as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine becomes shorter and more curved due to disuse and the effects of gravity . Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again?No, because old people don't really shrink!It is not that they are growing backwards--their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy ? Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity and motion sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning , the system goes out of control, and your brain thinks you're moving while you're not! Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area--from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet. Why do some old people look a little shrunken as they age?
Choices:
A. Their spine is in active use.
B. They are more easily affected by gravity.
C. They keep growing backwards.
D. Their spine becomes more bent. | D |

The world itself is becoming much smaller by using modern traffic and modern communication means . Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it. Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world. Air pollution is still the most serious. It's bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily. Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air. The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution. The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must try to control the growth of population at the same time. What is the most dangerous problem of air pollution?

A. CO2
B. H2O

My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it's a gift while others simply think I talk too much. As my thirties came to a close, I found myself reflecting on my life. I'm very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator ; I didn't seem to know when to stop talking. Whether it was hurting someone's feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet. To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He's highly intelligent and has wonderful opinions but he'll sit quietly and just listen. Even when he's asked a pointed question, he'll answer with few words while still communicating effectively. What a talent! Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers--they either didn't feel confident enough to speak up, or they just didn't feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers. The first one didn't work for me. I'm just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn't work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it's so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. _ An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells. I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet. As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I've found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success. By "I had to look further", the writer means she had to _ .
Choices:
A. look into the future in order to succeed in practicing the power of quiet
B. try harder to prevent herself from talking too much
C. survey people in other areas who talk little
D. find out other reasons why she should talk less | D |

While waiting to pick up a friend at the airport in Portland, Oregon, I had an experience which occurred merely two feet away from me. Trying to locate my friend among the passengers coming through the jet way, I noticed a man walking toward me carrying two light bags. He stopped right next to me to greet his family. First he kissed his three children one by one and said, "It's nice to see you. I missed you so much!" Then he hugged his wife, "I've saved the best for last!" giving her the longest, most passionate kiss I ever remember seeing. They stared at each other's eyes, smiling at one another, while holding both hands. For an instant they reminded me of newlyweds , but I knew by the age of their kids that they couldn't possibly be. Full of admiration, I asked, "Wow! How long have you two been married?" "Being together for fourteen years total, married twelve of those." He replied, without breaking his gaze from his lovely wife's face. "Well, then, how long have you been away?" I asked. "Two whole days!" "Two days?" I was astonished. By the intensity of the greeting, I had assumed he'd been gone for at least several weeks --- if not months. I knew _ so I turned away my eyes and said quietly, "I hope my marriage is still that passionate after so long!" The man suddenly stopped smiling and looked me straight in the eye. With forcefulness he told me something that left me a different person. "Don't hope, friend...decide!" Then he smiled again, shook my hand and said, "God bless!" With that, he and his family turned and walked away together. I was still watching that man and his special family walk just out of sight when my friend came up to me and asked, "What are you looking at?" Without hesitation, and with a curious sense of certainty, I replied, "My future!" From the passage, we can infer that _ .

Mike Maietta was eating lunch when he got a text message from his mom. "Notre Dame," it said. " _ !" Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big trouble. So Mike and his parents are considering offers from several other colleges and are figuring out the costs of tuition, housing and holiday trips home. This year, money is the driving factor for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and house prices have changed family spending. "We're excited that Mike got into eight great schools," said Mike's father, an engineer at Microsoft. "But if you consider going to school out of state, you've got to think about all of the other costs: moving, flying back and forth for the holidays. You're looking at about $3,000 a year, just for travel." As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased. Rachel Brown was happy to get a thick envelope from New York University (NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego (UCSD), because of the high cost in New York. "The tuition for NYU is twice as much as UCSD," said Rachel, 17. "My mom doesn't want me to have a big debt when I graduate, and I don't want that either. I'd have to take out a loan of $15,000. I'll check and see if there's any way that NYU can offer me any financial aid." More than 7.6 million American students have filled out the Free Application for Students Aid, 19.9 percent increase over last year. This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000. The passage mainly focuses on _

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize. Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants are able to quantify substances --like sand or water--as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food. With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount. "Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don't seem to count things like water or sand," vanMarle said. "What we're saying is that they can quantify substances; The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one." This information further refutes the long-held idea that babies "know nothing of the world," vanMarle said. "Since psychologists have begun studying infants with sensitive measures, we've discovered a lot of early abilities. I think for parents, it should be exciting to know that there's somebody there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development," vanMarle said. In the future, vanMarle says this kind of study could be linked to a child's progress in math-related skills, although programs marketed to increase those abilities, such as "Baby Einstein," still have mixed reviews when it comes to academic study. The quantifying ability refers to the ability to _ .
Choices:
A. choose between different substances
B. get much knowledge of the world
C. describe the quantity of something
D. obtain math-related skills | C |

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life. Blue/Purple Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight. A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer. Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc. Green We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer. Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene . Diets high in those above are associated with lowered blood pressure." Foods that contain the green color are: broccoli, cabbage, cucumbers, etc. Red Lycopene in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks. Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce." Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc. Orange The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A. "Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach.

People often ask me how, as a man, I became so devoted to improving the quality of women's lives. It wasn't until age forty that I realized what had started me down my career path. One morning more than thirty-seven years ago, I was awakened by the passing school bus. I was thirteen years old, living at home with my two younger brothers and our mother, Doris Joy Heavin. She had just passed her fortieth birthday. She was a mother of five children and had suffered emotional and physical problems most of her life. Her doctor had tried various treatments on her with little benefit. As I awoke to the sound of the passing school bus, my brother Paul came in and told me that I'd better come quickly because mother was sick. As I knelt beside her bed, I could feel the absence of warmth. I put my arms around her, first to feel for a sign of life, and then as a final hug. I took my younger brothers, aged eight and nine, in my arms and gently told them that our mother was in heaven. Her death was unnecessary. The high blood pressure causing the blood clot that took her life was unnecessary. Rather than _ , she could have dealt with the cause of her high blood pressure: we now know that exercise and proper nutrition will almost always reduce the causes of high blood pressure and most other chronic diseases. Many years later, while teaching a fitness and weight loss class to a group of about eighty women, I realized I was subconsciously searching the crowd for the face of my mother. From the passage we learn that _ .

"Whoosh!" The ball flew into the net and the game was finally over. This game had gone into overtime twice. Until the last goal was scored, no one had any idea which team would win. Dave felt so bad because his team had lost. He liked playing soccer, but he liked winning even more. Now the two teams should have a picnic together. Dave did not want to eat lunch with the other team. The other team would probably brag by talking about how they won the game. Dave went to the locker room to change out of his soccer clothes. There the coach talked to the team about what they had done well. They also talked about how they could improve. Then everybody walked outside towards the picnic table. One of the players from the other team was standing near the picnic table. He handed Dave a paper plate. "Hi, I'm Miguel," he said. "Hi," Dave replied, looking down at the ground. "You played great," Miguel said. "I didn't think we were going to win." Dave was surprised. Miguel was not bragging at all. "Thanks," Dave said to Miguel. "You played great, too." Dave felt happy.

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

Kenya is the first country to protect elephants by text messages. Mobile phone SIM cards are inserted in the collars of elephants. The cards will send a text message when the elephants wander too close to farms, allowing wildlife protectors to drive them off rather than shoot them. Hungry elephants cause big problems for farmers and villagers in some parts of Kenya when they are searching for food. Two years ago the Kenyan wildlife service had to unwillingly shoot five elephants who continued to destroy crops. In order to prevent such bad activities, the Elephants charity put a mobile phone SIM card on a huge bull elephant called Kimani. The conservationists then set up a virtual fence. Each time Kimani came near the fence, a text message was sent to farmers. So far he's been stopped from going into the danger area fifteen times. The project seems to be working successfully as Kimani hasn't come near a farm for four months. A similar system has now been put into operation in another part of the country. One of the biggest benefits of the project is that elephants seem to learn from one another, which can help a whole group change their habits. The elephants can also be tracked using Google Earth software. This is also helping the protectors know where to use their resources to protect the animals well. Elephants often cause problems in Kenya, because _ .
Choices:
A. they are attacked
B. they are angry
C. they are sad

Many of us use them several times a day without really noticing. And yet the way we behave in lifts, or elevators as they are known in the US, reveals a hidden anxiety. Passengers seem to know instinctively how to arrange themselves in an elevator, like the dots on a die. With each additional passenger, the bodies shift, going into the open spaces. On your own, you can do whatever you want--it's your own little box. If there are two of you, you take different corners, creating the greatest distance. When a third person enters, you will unconsciously form a triangle. And when there is a square, with someone in every corner, a fifth person is probable going to have to stand in the middle. Why are we so awkward in lifts? "You don't have enough space," says Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin. "Usually when we meet other people we have about an arm's length of distance between us. And that's not possible in most elevators, so it's a very unusual setting. It's unnatural." But perhaps there is more to it than just social awkwardness. "In the back of our minds we are a little anxious," says Nick White, an officer in New York who was unfortunate enough to be trapped in a lift for 41 hours. "We don't like to be locked into a place. We want to get out of the elevator as soon as possible, you know, it's a frightening place to be." During his terrible experience, he began to think of another enclosed space--a tomb. Dr. Lee Gray agrees that a sense of powerlessness is the main cause of lift anxiety. "You're in a machine that's moving, over which you have no control. You cannot see the elevator engine, you don't know how it's working." he says. What does the text mainly talk about?
Choices:
A. People's behavior in lifts.
B. Accidents in lifts.
C. The function of lifts.
D. Differences between lifts and elevators. | A |

I learned to look at my troubles differently because I know I'll grow in difficult times. A year ago. I visited my old high school hoping to see Profe. But he had retired. My high school helped me contact him. Now we stay in touch through e-mail. The author William Arthur Ward wrote: "The ordinary teacher tells. The good teacher explains. The superior teacher shows.

For years scientists have been worried about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse. Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution. People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building--green plants. Scientists do not really know how plants control air pollution. They believe that a plant's leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place. The reason why we should use different kinds of plants to clean the air is that

A. plants can let out all kinds of pollutants indoors

While we are still children ,most of us live at home with our parents, more or less peacefully . But as we become teenagers , things change ,and we begin to grow apart from our parents . This means we are almost ready to leave the house where we grew up and make a new home of our own . All humans must do this ,but they don't all do it in the same way . If ,for instance ,you belong to a primitive tribe ,then as you grew up ,you'd learn the skills you needed as an adult---how to catch fish ,how to keep the house and look after children . You would be ready to marry in your early teens and you would build a house and live near your family in the village. This seems a very old way of life , but it is what humans have been used to through hundreds of years. And it is what we are still used to in the 21stcentury ,for man hasn't changed in the short time since he became civilized . But could you leave home and look after yourself during the teen years ? Most people would not do very well . Why ? Because although man hasn't changed very much , the society he lives in has changed greatly ,which means that we have to learn more and more before we are ready to leave our parents' shelter( ) and live alone . However ,sometimes it is very frustrating to live at parents' home . Parents can be very upset about late nights ,criticizing friends and always saying that we are noisy and dirty .

mmlu | Question:
There are two kinds of changeschemical change and physical change. In a chemical change, there is always a new substance formed. Breaking up water into hydrogen and oxygen is a chemical change. In each of the chemical change at least one new substance is formed. A change is not a chemical change if it doesn't form a new substance. Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with lathe . Here paper is still paper, and the iron is still iron. Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears. You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dissolving of anything is a physical change. When water freezes, the change is also a physical one.
