mmlu | Question:
Farmers could grow more rice and shaky Internet communications could work better someday, thanks to prize-winning discoveries by teenage scientists showed at a national science fair on Monday. High school scientists from across the United States showed off work in genetics, molecular biology, mathematics and other fields that judges said rose to the professional level. "It just blows me away. They're all just unimaginable," said Joel Spencer, aprefix = st1 /New YorkUniversityprofessor who served as judge at the Sidemen's Westinghouse Competition in Math, Science and Technology. Research done by finalists in the nationwide competition could lead to faster Internet speeds, more effective antibacterial drugs and better energy conservation. One team researched black holes in outer space, while another examined more than 700 fossils to better understand why dinosaurs died out. Juliet Girard and Roshan Prabhu won $ 100,000 scholarship for their work proving genes that help some kinds of wild rice flower earlier than others. Drawing on a database that described the genetic makeup of rice, the two students, fromJersey City,New Jersey, identified two genetic sections that directed wild rice to blossom an average of 10 days earlier than the ordinary short-grain rice that feeds much of the world. Their discovery could allow genetic engineers to develop a new strain that would take less time to reach maturity, allowing farmers to produce more and extending the growing region into colder climates. Steven Byrnes of Lexington,Massachusetts, took the top individual prize for his theory describing outcomes in a two-player game called Chomp. What Juliet Girard and Roshan Prabhu discovered may lead to _ .
Choices:
A. an important development in agriculture
B. faster Internet speeds.
C. their top individual prizes
D. better energy conservation | A |

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

mmlu | Question:
Graham and his friends preferred to shoot up in their arms, necks and legs. A dealer once said Graham was the type who would never be able to turn back and that he expected him to die from the drug. Wendy feared the same, but didn't know how to save her son. " Once, after he'd disappeared for more than a month, I found him at a friend's house with a bunch of other users," she said, "I got down on my hands and knees, begging him to come home. He did, but the next morning he was gone. I don't know what made him do it, but I drove 20 miles to the nearest train station. Graham was headed for Seattle, his pockets full of drugs. If I hadn't gotten there in time, I would never have seen him alive again." The turning point came in 2007, after Graham was arrested yet again for possession. Wendy got a call from the Montana Drugs Project, which works with local law enforcement to keep track of youth-related crimes so it can help families in trouble. Following a counselor's advice, Wendy hired two men to come to her home in the middle of the night, tie Graham and take him to a treatment program in Thompson Falls, Montana. "I was high when they came and really angry with my mom," he said, "But if she hadn't done that, drugs would have killed me." After six months of treatment, Graham, now 19, came back to Kalispell, where he's grown close to Wendy once again. "I still have the desires every day and attend support meetings every night," he said, "But life is worth living again. My mom thinks that's a miracle. I guess she is right." When the two men came to their home in the middle of the night, Graham _ .

Nails in the Fence There once was a little boy who had a bad temper . His father gave him a bag of nails and told him that every time he lost his temper, he must hammer a nail into the back of the fence. The first day he had driven 37 nails into the fence. Over the next few weeks, as he learned to control his anger, the number of nails hammered daily gradually _ . He discovered it was easier to hold his temper than to drive those nails into fence. Finally the day came when the boy didn't lose his temper at all. He told his father about it and the father suggested that now pull out one nail for each day that he was able to hold his temper. The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence.

You can put a knife in a man and draw it out. It won't matter how many times you say 'I am sorry ', the wound is still there. A verbal wound is as bad as physical one." The little boy then understood how powerful his words were. He looked at his father and said " I hope you can forgive me ,father, for the holes I put in you." "of course I can," said the father. When you say something with anger, they will leave a scar just as you put a nail in and then draw it out. It means _ .

mmlu | Question:
You may have known several kinds of police --- traffic police, fire police and street police. But have you ever heard of energy-saving policeman? A group of 22 energy-saving policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning no cooler than 26degC. They also set up a special phone line so that people can tell them which buildings fail to follow the rule. "If everyone sets their air conditioning at 26degC, Beijing will save 400 million kilowatthour of electricity in one summer. That's one-third of all the usages of the city in the season," said a TV advertisement. Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiansu Province, are going to follow Beijing's steps in setting up a similar police team. As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country's environment and limited energy. From 1986 to 2005, the country experienced 20 warm winters continuously . Numbers show that Chinese cities have to spend billions of yuan solving environmental problems every year. At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable energy up to 10% from 7% by 2010. To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps collect used bottles, have attracted lots of attention. "We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it on our daily lives," said Liu Qianguang, an environmental engineer in Beijing. According to Liu Qianguang, _ .
Choices:
A. there are few ways to protect the environment
B. it's difficult to find good ways to save energy
C. it's easy for one to do something good for the environment
D. it's difficult for one to do something good for the environment | C |
mmlu | Question:
What will man be like in the future--in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller, so we may assume that man will continue to grow taller. Again, as time goes on, we shall have to use our brains more and more. This is likely to bring about a physical change to the head, in particular, the forehead will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we are likely to make less use of our arms and legs, which, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. Perhaps all these give the impression that in the future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. According to the passage, we can learn that _ .
Choices:
A. human beings will become less attractive in the future
B. less use of a part of the body will become weaker
C. human beings hope for a change in the future life
D. future life is always predictable | B |

mmlu | Question:
People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think." In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity , a 25% increase in the risk for abnormal blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol . All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It's something that surprised even the researchers. Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that." In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study. How does the writer present the passage?
Choices:
A. By comparing opinions.
B. By giving advice.
C. By showing facts.
D. By discussing information. | A |
mmlu | Question:
When I paid for the bicycle repair, the repairman told me, " No change, Professor Pan. We're friends." "I'd rather pay," I replied. "If it's free, I can't afford it." Chinese often refuse payment for professional services, insisting, "We're friends now!" But then they show up later to ask me to tutor them in English, or get them into an American university, and I wish I'd have just paid the 30 yuan I owed them in the first place. According to the Americans, "There's no free lunch," meaning that there's a price for everything, and I'm always looking around to figure out what this means. Many of our neighbors have given us fruit or flowers or costly teas, never asking anything in return. For years, a bicycle repairman has repeatedly refused to let me pay him. "Wait until you have something major to fix!" he insists. Chinese generosity is a real education for Americans like me, who would rather avoid social entanglements and just hand over the money. But cash can't make up for the greatest gift - friendship. When an American saw some of my friends sitting on bamboo stools under the trees, sipping tea, he said, "They must have nothing better to do." "Actually," I said, "they are professors, with plenty to do. But probably you're right in saying that, at this moment, they have nothing better to do. And neither do I." And I joined the group. We chatted about tea and Chinese cooking and how much my boys have grown since we arrived. One man said, "They were pocket-sized when you came here. Now they're taller than you. How time flies." How life flies. And Chinese are smart enough to share what they know they cannot keep. They freely give of their time, never too busy to help a friend. And they are teaching me, slowly, to both give and receive. So the next time someone says, "No charge. We're friends." I will thank them heartily. But if they show up later asking me to tutor them in English, I'll make sure they tutor my son in Chinese as well, because there's still no free lunch. The best title for the passage should be " _ ".
Choices:
A. Still No Free Lunch
B. A Good Lesson from Chinese
C. True Help or Not
D. Learn to Both Give and Receive | A |

mmlu | Question:
So many of us hold on to little complaints that may have come from an argument ,a misunderstanding,the way we were raised,or some other painful events. Stubbornly,we wait for someone else to reach out to us -- believing this is the only way we can forgive or _ a friendship or family relationship. A friend of mine,recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out,she said," I can't do that. He's the one who should apologize. " After a little gentle encouragement,however,she did decide to be the first one to reach out. To her amazement,her son was grateful for her willingness to call and offered an apology of his own. As is usually the case,when someone takes the chance and reaches out,everyone wins. Whenever we hold on to our anger, we turn" small stuff")"into really" big stuff" in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go,and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go,as well as the joy of letting others be right. You'11 also notice that,as you reach out and let others be "right",they will become less defensive and more loving toward you. They might even reach back. But,if for some reason they don't, that's okay too. You '11 have the inner satisfaction of knowing that you have done your part to create a more loving world,and certainly you'11 be more peaceful yourself. The best thing to do after a quarrel is to .

A. let go of our own rights
B. realize that you are wrong.

mmlu | Question:
Which animal has the fastest snapping jaw ? If you're guessing a shark or perhaps a larger animal, you'll have to think smaller. The trapjaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second. Another way to think about this is that the ant's jaws close at 125 to 233 kilometers per hour. That's 2, 300 times faster than the blink of an eye. Scientists were able to measure the amazing jaw speed using highspeed video techniques. Sheila Patek, a biologist, says the key is that the jaws have a springy system, which is critical in getting explosive speeds. Consider a bow and arrow. If you try to throw an arrow with your arm, it won't go very far. If you use a bow, elastic energy stored in the bow is released almost instantly when you release the arrow with your finger or a latch. The combination of the springy bow and latch mechanism is what makes the arrow zoom through the air. Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move. As the ant closes its jaws, it uses them to push off the ground--all faster than the eye can see without slow motion video. A snap of the jaw can send an ant up to 8.3 centimeters into the air. That's like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once. It would be hard for their enemies to grab just one. People have suspected the ants used their jaws to jump for over a century, but could only prove it with today's modern video equipment. According to the passage, the trapjaw ants' jaws keep them safe because _ .
Choices:
A. they can catch their enemies easily with their jaws
B. their jaws make them difficult to recognize
C. their jaws help them find food easily
D. their jaws help them escape from their enemies | D |
mmlu | Question:
Before the opening of the Cape Cod Canal in 1914,the only way ships could leave Boston was on a route around Race Point--the northern tip of Cape Cod.However,navigation during the 18th century was a nightmare,because the floating cross current around Race Point caused countless accidents.So building a lighthouse to lighten the place was very necessary. As early as 1808,the people of Provincetown requested a lighthouse on Race Point,but it took Congress eight years to react when they finally paid $ 8,000 on April 27,1816 to build a lighthouse --Race Point Light,which was located in the town of Provincetown,Massachusetts.It was first built of stone 25 feet high with no foundation and its light was 30 feet above the sea.It was equipped with one of the nation's earliest revolving lights. Actually,there were two other lighthouses on Cape Cod,but they were hit by a storm in October 1841.In the following year,Race Point Light was examined by I.W.P.Lewis,who realized the light's importance.He said,"The light should be useful to all ships leaving Boston.However,its _ power is so weak that people would hardly be able to differentiate it from the lights set on the ships which stay in the bay,or close by.It hasn't played its role as a lighthouse well." The result was that old lighthouse was destroyed and a new iron lighthouse with a proper foundation was put up to take its place.The new lighthouse was 45 feet high.Although the original keeper's house was in good repair,it was destroyed too and a new one was built.Today the lighthouse has been automated and Race Point Light is still an active aid to navigation. You can park at Race Point Beach and walk about 45 minutes to the lighthouse.Sunset at Race Point Light is one of the Cape Cod's most popular scenes.And at times whales can be seen in the lighthouse.For reservations to stay one night in the keeper's house at Race Point call(508)487-9930. What does this passage mainly talk about?
Choices:
A. The building process of Race Point Light.
B. The tourism value of Race Point Light.

A serious earthquake can be a terrible experience, and it is easy to forget safety measures in disorder . _ , most earthquake safety measures are common sense, but if you forget everything else, remember the following instructions: drop, cover, and hold on. Also, most of earthquake deaths happen after the earthquake, so remember that the danger does not end when the shaking does! If you stay indoors during an earthquake, move away from unsupported areas and windows. Try to get under a doorway or another area of the building which is held up by strong beams . Stay under a table or desk only if it is very strong. Do not rush to lifts, because it is far safer to stay where you are. Cover your head with your arms around it and curl into a ball, and wait for the shaking to stop. If you stay outdoors during an earthquake, move to an area which is as open as possible. Don't move to buildings, electric poles and other objects which may fall during an earthquake and injure you. Protect your head and stay low to the ground till the shaking ends and it is safe to move. After an earthquake, many buildings are less strong, although they appear safe. If you stay indoors, move people from the building quickly and help disabled or injured people. Once outdoors, move well away from the building so that if it falls down, you will not be injured. Wait till public safety officials announce that it is safe to stay indoors. By planning ahead and keeping calm during an earthquake, you can greatly increase your chances of survival without injury. We can learn from the passage that earthquake safety measures _ .

mmlu | Question:
Dennis Sinar, 51, a doctor from New York, is quick to explain why he took a year-long break from his job. "I was pretty burned out after practicing medicine for 26 years. I needed a recharge." So he took a "gap year", from July 2011 to June 2012, to explore things like ancient buildings, and traditional Eastern medicine, in locations including Alaska, Nepal and Romania. "Taking a break from work is an excellent way for adults to go into a new career or refresh an old one," said Holly Bull, president of Princeton, N, J. "In recent years, mid-career breaks have been gaining more interest," she said. A report on adult gap years published this year by a market research company also described the potential American market for gap years as a "sleeping giant." "A gap year is a challenge for the older individual to step out of a comfort zone and take a risk. I enjoyed that side most." said Dr. Sinar, who kept a daily blog about his experience. His time studying Eastern medicine "assured the reasons I went into health care," said Dr. Sinar, who returned to practice medicine at his old job, although he works fewer days. "I use those experiences to provide my patients with more care," he added. "And I listen better than I did before." George Garritan, chairman of the Department of Leadership and Human Capital Management at New York University, certainly agrees with Dr. Sinar. He said a gap-year experience could be worthwhile for employees and companies. For employees, investing in themselves and improving skill sets is a move that will benefit throughout their career. He added that returning employees feel refreshed and have given more thought to their career. For companies, offering unpaid leaves makes good sense for attracting and keeping talented employees. What's the passage mainly about?
Choices:
A. How an adult plans a mid-career gap year.
B. Why a gap year is worthwhile for adults.
C. Whether a gap year is popular with adults.
D. Why a gap year is challenging for individuals. | B |

It is now commonly known that AIDS is a deadly disease. It does great damage to human beings' immune system, weakening resistance to disease and leading to death due to utter weakness. To this day, there are no existing drugs that can kill AIDS virus. It is a deadly battle between science and AIDS. This is only one side of the story. Although it can not be cured, AIDS is preventable. For those who have not caught the disease, the knowledge of preventive measures seems to be the most powerful weapon at hand. Since the discovery of the first AIDS patient in 1985, the number of HIV carriers is on an alarming rise in China and statistics show that young people are the more likely victims of AIDS. Nationwide there are 214 million people between the ages of 13 and 22, most of whom are students. If no measures are taken to protect these young people, it is almost certain that the threat of AIDS will be very real to them. There has been a great deal of misinformation concerning the transmission of AIDS. One of the most misleading myths is that AIDS can be transmitted by casual physical contact such as kissing, shaking hands or sharing food container. Surveys and investigations conducted in some universities and colleges show that half of those people questioned are not clear about how AIDS is transmitted, not to mention how it is prevented. This is the driving force behind the State Education Department's decision to spread AIDS awareness information among college students and later to high school students and primary school students. By writing "This is only one side of the story", the author suggests that _ .
Choices:
A. although we can't cure AIDS, we can manage to prevent it.

mmlu | Question:
Walking down a path through some woods in Georgia, I saw a small pool of water ahead on the path. I angled my direction to go around it on the part of the path that wasn't covered by water or mud. As I reached the pool, I was suddenly attacked! Yet I did nothing for the attack. It was so unpredictable and from somewhere totally unexpected. I was surprised as well as unhurt though I had been struck four or five times. I backed up a foot and my attacker stopped attacking me. Had I been hurt I wouldn't have found it amusing. And I was laughing. After all, I was being attacked by a butterfly! Having stopped, laughing, I took a step forward. My attacker rushed me again. He charged towards me at full speed, attempting to hurt me but in vain. For a second time, I took a step backwards while my attacker paused. I wasn't sure what to do. After all, it's just not everyday that one is attacked by a butterfly. I stepped back to look the situation over. My attacker moved back to land on the ground. That's when I discovered why my attacker was charging me only moments earlier. He had a mate and she was dying. Sitting close beside her, he opened and closed his wings as if to fan her. I could only admire the love and courage of that butterfly in his concern for his mate. He had taken it up on himself to attack me for his mate's sake , even though she was clearly dying and I was so large. He did so just to give her those extra few precious moments of life, should I have been careless enough to step on her. His courage in attacking something thousands of times larger and heavier than himself just for his mate's safety seemed admirable. I couldn't do anything other than reward him by walking on the more difficult side of the pool. He had truly earned those moments to be with her, undisturbed. Since then, I've always tried to remember the courage of that butterfly whenever I see huge barriers facing me. What made the man feel funny?
Choices:
A. Making the attacker pause.
B. Being attacked by a butterfly.

A young man learns what's most important in life from the guy next door. It had been some time since Jack had seen the old man. College, girls, career, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of his dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him. Over the phone, his mother told him, "Mr. Belser died last night. The funeral is Wednesday." Memories flashed through his mind like an old newsreel as he sat quietly remembering his childhood days. "Jack, did you hear me?" "Oh, sorry, Mom. Yes, I heard you. It's been so long since I thought of him. I'm sorry, but I honestly thought he died years ago," Jack said. "Well, he didn't forget you. Every time I saw him he'd ask how you were doing. He'd reminisce about the many days you spent over 'his side of the fence' as he put it," Mom told him. "I loved that old house he lived in," Jack said. "You know, Jack, after your father died, Mr. Belser stepped in to make sure you had a man's influence in your life," she said "He's the one who taught me carpentry," he said. "I wouldn't be in this business if it weren't for him. He spent a lot of time teaching me things he thought were important...Mom, I'll be there for the funeral," Jack said. As busy as he was, he kept his word. Jack caught the next flight to his hometown. Mr Belser's funeral was small and uneventful. He had no children of his own, and most of his s had passed away. The night before he had to return home, Jack and his Mom stopped by to see the old house next door one more time. Standing in the doorway, Jack paused for a moment. It was like crossing over into another dimension, a leap through space and time. The house was exactly as he remembered. Every step held memories. Every picture, every piece of furniture....Jack stopped suddenly. "What's wrong, Jack?" his Mom asked. "The box is gone." he said. "What box?" Mom asked. "There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he'd ever tell me was 'the thing I value most'." Jack said. It was gone. Everything about the house was exactly how Jack remembered it, except for the box. He figured someone from the Belser family had taken it. "Now I'll never know what was so valuable to him." Jack said. "I better get some sleep. I have an early flight home, Mom." It had been about two weeks since Mr. Belser died. Returning home from work one day, Jack discovered a note in his mailbox "Signature required on a package. No one at home. Please stop by the main post office within the next three days." the note read. Early the next day Jack retrieved the package. The small box was old and looked like it had been mailed a hundred years ago. The handwriting was difficult to read, but the return address caught his attention. "Mr. Harold Belser" it read. Jack took the box out to his car and ripped open the package. There inside was the gold box and an envelope. Jack's hands shook as he read the note inside. "Upon my death, please forward this box and its contents to Jack Bennett. It's the thing I valued most in my life." A small key was taped to the letter. His heart racing, as tears filling his eyes, Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the finely etched casing, he unlatched the cover. Inside he found these words engraved: "Jack, Thanks for your time! -Harold Belser." "The thing he valued most was...my time" Jack held the watch for a few minutes, then called his office and cleared his appointments for the next two days. "Why?" Janet, his assistant asked. "I need some time to spend with my son," he said, "Oh, by the way, Janet, thanks for your time!" Why did Jack think Mr. Belser died years ago?
Choices:
A. College and career prevented him from remembering Mr. Bleser.
B. Jack was too busy with his business and family to think about Mr. Belser.
C. Jack was too busy realizing his dreams to think about Mr. Belser.

mmlu | Question:
In ancient Greek mythology we learn about a young man named Narcissus. He was so beautiful that he fell in love with his own reflection . He became obsessed , but soon realized that what he loved was not real. As a result, he became sad and died. In the place where he had stood appeared a soft yellow flower -a narcissus. This is where the word "narcissism" came from. Unfortunately, narcissism is often used to show disapproval because it is usually used to mean being self-centered and not caring about others. However, part of the reason that narcissism carries these negative meanings is that many people admire themselves in an unhealthy way. But the truth is that good self-love is necessary for our mental health, scientists say. A study published 10 years ago shows that low self-esteem is responsible for many social problems, and it can affect teenagers seriously. When they feel less confident and not as good as their classmates, teenagers are more likely to suffer from depression, commit suicide, get pregnant and bully others, according to the BBC. The other reason that narcissism is considered an ugly thing is because we are taught that we should care more about others than ourselves and that it's better to give than to receive. Thinking about others is the right thing to do, without question. But psychologists say that the love of others is actually based on self-love. If you see yourself as an unpleasant stranger, how can you be capable of making friends with anyone else? After all, you are closer to yourself than anyone else. After years of study, scientists also found that parents play a big part in building a child's self-belief. Only if the parents approve and accept their children, do they feel loved and learn to love themselves. The next time you look in the mirror, try to tell yourself that you are one of a kind. Pick out your best qualities and be proud of yourself. It is suggested in the article that _ .

Now that military dogs are taking on a larger role in fight, they' re also taking on more of the risks that come with going to war, including developing post-traumatic stress disorder.The New York Times reports that more than 5 percent of the approximately 650 deployed military dogs are developing some form of canine PTSD . "It really is difficult, because cace the dog experiences these traumatic explosions, it's the same as the troops," Army Lt.Col. Richard A Vargus, chief of the law enforcement branch at CENTCOM told the Military Times in September."Some dogs move right through it and it doesn't affect them.Some dogs, it takes some retraining, and some dogs just refuse to work." Like humans, military dogs exhibit a range of changes in temperaments when they develop PTSD.Some become aggressive, others retreat.But because dogs can't express what the problem is, soldiers can be put at risk if their partner simply stops doing his job without warning. "If the dog is trained to find improvised explosives and it looks like it's working, but isn't, it' s not just the dog that' s at risk," Dr.Walter F.Burghardt Jr., chief of behavioral medicine at the Daniel E.Holland Military Working Dog Hospital at Lackland Air Force Base, told the Times."This is a human health issue as well." And searching for such devices has become a key responsibility for military dogs.Even after spending six years and nearly $ 19 billion on experimenting with innovative ways to detect bombs, the Pentagon admitted in 2010 that its most sophisticated technology was no match for a dog' s nose. "Electronic equipment is great in the laboratory, but out on the battlefield, you can't beat the dogs," Bill Childress, manager of the Marine Corps working dog program told the Los Angeles Times. Just as physicians have yet to find a safe way to treat PTSD among humans, so too are veterinarians weighing a wide range of options when it comes to helping their canine patients But offering dogs the same innovative treatments that their human counterparts get, doesn't guarantee a full recovery.It's a fact that fears once learned are never unlearned. What is the theme of the passage?

A. Military Dogs Are Hard to Train
B. Electronic Equipment And Military Dogs
C. Military Dogs Play A key Role In Wars

mmlu | Question:
Many everyday American expressions are based on colors. Red is a hot colour. Americans may say they are red hot about something unfair. They are red hot when they are very angry about something. The small hottasting peppers found in many Mexican foods are called red hot for their colour and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz. Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The expression was first used in America at the beginning of the twentieth century. It comes from the fact that many babies are born with nice pink skin that shows that they are in good health. The colour black is often used in expressions. People describe a day on which everything goes wrong as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations. The colour green is natural for trees and grass. But it is,an unnatural colour for humans. A person who has a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green. Sometimes a person may be upset because he does not have something as nice as a friend has. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because green is the colour of the back side of the paper money. Americans use "red hot" to describe the following EXCEPT _ .

mmlu | Question:
After 20 years as a full-time wife and mother, I decided to be a school bus driver for I loved kids. After hard practice, by the time school started that year I'd gotten the hang of it. I was happy in my new work. I became a combination of chauffeur, nurse and friend. And if the kids needed it, I'd put on my "Tough Big Sister" act. It was a lot like my previous job---being a mom. When I think about my years of bus driving, many things crowded in, but mostly, I remember Charlie. Charlie, eight years old, with blond hair and crystalline gray eyes, began riding my bus in September of my fourth year driving. They all had stories to tell me about their summers. Charlie, though, ignored me. He didn't even answer when I asked his name. From that day on, Charlie was a trial. If a fight broke out I didn't have to turn my head to know who had started it. If someone was throwing spitballs I could guess the culprit's name. If a girl was crying, chances were Charlie had pulled her hair. No matter how I spoke to him, gently or firmly, he wouldn't say a word. He'd just stare at me with those big gray eyes of his. I asked around some, and found out Charlie's father was dead and he didn't live with his mother. He deserves my patience, I thought. So I practiced every bit of patience I could muster. To my cheery "Good Morning", he was silent. When I wished him a happy Halloween, he sneered. Many, many times I asked God how I could reach Charlie. "I'm at my wit's end." I'd say. Still I was sure that this child needed to feel some warmth from me. So, when he'd pass by, I'd ruffle his hair or pat him on the arm. Toward the end of that year, the kids on my bus gave me a small trophy inscribed "To the Best Bus Driver Ever". I propped it up on the dashboard. On top I hung a small tin heart that a little girl had given me. In red paint she had written, "I love Polly and Polly loves me." On the next-to-last day of school I was delayed a few minutes talking to the principal. When I got on the bus I realized that the tin heart was gone. "Does anyone know what happened to the little heart that was up here?" I asked. For once with 39 children, there was silence. One boy piped up, "Charlie was the first one on the bus. I bet he took it." Other children joined the chorus, "Yeah! Charlie did it! Search him!" I asked Charlie, "Have you seen the heart?" "I don't know what you're talking about," he protested . Standing up, he took a few pennies and a small ball out of his pockets. "See, I don't have it." "I bet he does!" insisted the girl who had given me the heart. "Check his pockets." Charlie glowered when I asked him to come forward. His gaze burned into mine. I stuck my hand into one pocket. Nothing. I reached into the other pocket. Then I felt it ---the familiar outline of the small tin heart. Charlie stared at me for a long time. There were no tears in those big gray eyes, no plea for mercy. _ I was about to pull the tin heart out of Charlie's pocket when I stopped myself. Let him keep it, a voice seemed to whisper. "It must have fallen off before I got here," I said to the kids. "I'll probably find it back at the depot." Without a word, Charlie returned to his seat. When he got off at his stop, he didn't so much as glance at me. That summer Charlie moved away. Eventually I retired. And there my story as a school bus driver ends, except for one more incident. A dozen years after retirement I was in a department store in Kansas City, when someone said tentatively, "Polly?" I turned to see a balding man who was approaching middle age. "Yes?" His face didn't look familiar until I noticed his big gray eyes. There was no doubt. It was Charlie. He told me he was living in Montana and doing well. Then, to my surprise, he hugged me. After he let go, he pulled something from his pocket and held it up for me to see. An old key chain....bent out of shape, the lettering faded. You can probably guess what it was---the little tin heart that said, "I love Polly and Polly loves me." "You were the only one who kept trying," he explained. We hugged again, and went our separate ways. That night I thought over his words. You were the only one who kept trying. Before I fell asleep I thanked the Lord for the reassurance that I'd done a good job and for all the qualifications he'd given me to do it with. Charlie kept the tin heart all the time because it reminded him _ .

A. it was a Christmas gift from Polly

mmlu | Question:
Earlier this year,my oldest daughter got braces on her teeth,and let's just say she did not go quietly into that dentist's chair. Fear and hate pretty much describe the days leading up to her first appointment. So when she finally walked out with shiny teeth,a sore mouth and a broken spirit, I told her I was proud of her and took her to Ben & Jerry's for an ice cream reward. Two weeks later, we returned to the scene of the crime.The dentist spent about 45 seconds checking her teeth before sending her on her merry way. Before I could start the car, she was placing her ice cream order. She was shocked when I told her that she wasn't going to get a reward every time we got her teeth checked. Apparently,she's not alone. According to some parenting experts, kids are easily addicted to a benefitproducing system of parental rewards and bribes --not all ice creams, candies and cool toys.Some parents are offering their children novel prizes just to let them sit down and behave in a restaurant--or sleep in their own beds--or score a goal in the next soccer game. While the experts agree that occasional awards are okay,the danger lies in the system's overuse.Kids quickly gain a sense of entitlement ,where they come to expect a big reward for every good thing that they do, no matter how small.To keep things in check,experts say parents should reduce the number of rewards they offer, make sure rewards match the behavior and explain the real benefits of behaving. What would be the BEST title for the passage?

It is reported by Chinese Xinhua News that students waste more food than the national average. So the campaign on school food waste is getting popular across the country. The move is part of a national campaign started by students at different schools. At East China University of Science, students who finish their food in the school dining hall get a special card when they return their plates after meals. Students can collect cards and exchange them for small gifts, such as books, schoolbags, magazines and umbrellas. "It's been such a surprise," said Liang Zhaoyun, 19, a student in Shanghai. "It has given us one more motivation to eat up our food." "The purpose of the campaign is not only to encourage students to finish their food. We hope it can also teach students to choose a more environment-friendly and healthy lifestyle," said Tao Siliang from University of Traditional Chinese Medicine. Other schools also pay attention to the quantity of food. At Nanjing No.9 Middle School, rice is divided into three different-sized bowls that students can choose from according to their own need. "It's great because I can try different dishes at half price and don't waste so much food," said Fan Peng, 15, a student from this middle school. What if you really can't finish all your food? At Changchun Normal College, they provide a take-away service. "If you can't finish all your food, you can get a box to take the left food home. Even if you feed the cat, it's not wasted," said Zhou Zeyong, a student who learns Chinese education. "I'm happy that we've cut down waste since joining the school 'eat-up' meeting. But some food is poorly cooked, meaning that students are not willing to finish it all. Some schools have taken note of this. So if we hope students try to waste less food, we should also improve the service and keep an eye on the meal quality on weekdays at school. If not, you can't complain students for throwing away much food," said Wang Guangji, the head-teacher of Beijing No. 29 Middle School. Why did we start the campaign on food waste at schools? Because _ .
Choices:
A. food waste at school is very serious
B. students should not eat more food
C. it is students' duty to eat less food
D. it's easy for schools to start a campaign | A |
mmlu | Question:
Linking the Red Sea to the Indian Ocean, the blue waters of the Gulf of Aden near Somalia are one of the most important trading routes in the world. But they are also the most feared. Pirates whose targets are ships and their crew often show up there. On September 25, a Ukrainian ship carrying 30 tanks became another victim. The pirates have reportedly killed one of the crewmen and are now surrounded by the US Navy. But they are still demanding $ 20 million for the release of the ship. This year alone, more than 50 ships have been attacked, 25 hijacked , and 14 are currently being held. Of course this is nothing new either. Ever since there has been water and ships there have been pirates. The earliest documented history of pirates dates back to the 13th century in the Mediterranean Sea. Even the famous Roman emperor Julius Caesar was kidnapped by pirates at one time. Piracy reached its peak in the early l700s, especially in the Caribbean and off the coast of Africa. In the mid-20th-century, most pirates we're common thieves. They used hooks to steal on board commercial ships, and took all that they could find. These pirates were more likely to flee than fight if met by the crew. However, nowadays piracy has become a multi-million dollar business attracting many in poor countries such as Somalia. "The pirates are well funded and have all the latest equipment, including satellite phones," said a top UN representative in Somalia. In Asia, however, a trend started where pirates didn't just want to kidnap the stuff, they also wanted to control the ship. They would kill the crewmembers or kidnap them for ransom . After the recent kidnapping of Ukrainian ship, people are also worrying that tanks and arms on board would fall into hands of terrorists. Last week the UN called a meeting from all affected countries to fight piracy. "The international community is determined to stop these pirates who are weakening efforts to bring peace to Somalia. This cannot and will not be allowed to continue," a representative said. We can infer from the passage that
Choices:
A. it is impossible to fight with piracy
B. no country has the determination to fight with pirates
C. no ships will be found in the Somalia area before the disappearance of pirates
D. more measures will be taken to fight with pirates | D |

A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men. The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue ofPsychological Science. Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, "What do you regard as your most serious fault of personality or character?" Pessimists were defined as fatalistic people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation. Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide). A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. "A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later," according to Peterson. According to the passage, pessimists may feel all of the following EXCEPT _
Choices:
A. helpless when faced with difficulties.
B. cheerful when faced with troubles.
C. hopeless when one bad event occurs.
D. guilty when things go wrong. | B |

Since my retirement from teaching music in 2001, I have spent a good deal of time painting as an artist, I actually began drawing again in the summer of 1995 when my father died. so perhaps I was trying to recover from the loss of my father, or maybe it was just that it brought back memories of him. In any case, I drew pen and ink animals and landscapes much influenced by Krenkel and St. John for five years. For some strange reason, I had been waiting until my retirement to start doing watercolor1s again, but as soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew Wyeth, who quickly became my favorite artist, I had looked through all the art books I had on my shelves and found his watercolor1s to be the closest to how I thought good watercolor1s should look. So I painted landscapes around Minnesota for three years and tried out many other types of painting. However, watercolor1s remained my first choice, and I think I did my best work there, showing my paintings at a number of art exhibitions. Art is now together with my piano playing and reading. There is a time for everything in my world, and it is wonderful to have some time doing what I want to do. As Confucius once said: "At seventy I can follow my heart's desire."

When I was growing up in the suburbs of New York, our first local Earth Day was organized around a drive to a town field where families were urged to empty items from their basements for recycling rather than dropping them in the dustbin. It was an eye opening idea for a kid in 1970. But as an environmental reporter, I'm bored of the large amount of deals and promotions that arrive by email or in my office or home mailbox on Earth Day. Like Valentine's Day, Earth Day has become a huge marketing opportunity--a way to promote consumption. In fact, Earth Day is such a good sales opportunity that some shops, like Target, have expanded Earth Day into Earth Month. There isn't time to give you a variety of the Earth Day shopping opportunities I was informed of this past week. They included deals on buying bottled water and earth-friendly wipes. My award for the silliest promotion: a plan to gift 25 of the most environmentally conscious stars with unique, useful and "green" products and services, including skin care products, cheese-cake and artwork. My guess is most of the stuff will end up in celebrities' garbage. Is buying and selling a good way to celebrate and protect the environment? I would argue that Earth Day might be an occasion to consider giving up purchases or habits that are environmentally questionable or that we could happily do without. How about not buying bottled water, but refilling a water bottle? How about not buying foods--even "organic" foods--that are packed in non-recyclable plastic? Don't get me wrong. The company of Bridgestone is celebrating Earth Day by promising to repurpose a spent tire for every tire that it sells. Verizon will plant a tree for each cell phone you trade in. Some coffee stores will even refill reusable cups at no charge. Target is giving out free reusable carrier bags without requiring a purchase. But few shopkeepers are taking the next step-charging a fee at the cash register for disposable plastic bags, a common practice in Europe-to encourage customers to use those new reusable carriers. Earth Day is transient . If you only showed love on Valentine's Day, would that really mean anything at all? It could be inferred from the text that Bridgestone and Verizon _ .

A. are likely to misunderstand the author
B. have a good way to celebrate Earth Day
C. are devoted to making money on Earth Day
D. make wrong promotion plans on Earth Day | B |

Barack Obama has never been shy about comparing himself with Abraham Lincoln. He did so when he announced his presidential election in Illinois, where both he and Lincoln served in the legislature . "The life of a tall, thin, self-made Springfield lawyer tells us that a different future is possible." Obama said. "He tells us that there is power in words and that there is power in hope." Such comparisons have continued on big and small occasions, but the most important similarity, in Obama's mind, is how he plans to govern if elected. Obama says he admires Doris Kearns Goodwin' s wonderful Lincoln biography, Team of Rivals. "He talks about it all the time." says a top assistant. "He is particularly interested in the idea that Lincoln successfully won the hearts of many people who had run against him for President, some of them even disagree with him firmly." "The lesson is that you shouldn't let your hatred get in the way of hiring ly the best people." says Obama. "I think American people are practical and so I have an interest in casting a wide net, seeking out people with a wide range of expert knowledge, including Republicans, for the highest positions in the government." "I don't want to have people who just agree with me." He says. "I want people who are continually pushing me forward and I'd be very interested in having those sorts of Republicans in my government, especially people who can speed up a responsible and logical conclusion to the Iraq war." What can we infer from the passage?
Choices:
A. Obama is a member of the Republicans.
B. The passage was written after the presidential election.
C. Doris Goodwin is one of Obama's assistants.
D. In the end Lincoln was able to get the support of the people who once hated him. | D |

Scientific Progress Most scientific progress is the result of careful consideration of work that has already been done. The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life's road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough. When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end. Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don't know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance. Our present wonderful world has been built up by _

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

All of us have taken an instant dislike to someone, and then felt guilty about being too judgmental. But now it seems we should place more trust in our first impressions. Most people can accurately judge a total stranger following a short meeting, according to scientists. And in general, the more confident the people are, the more likely they are to be correct in their assumptions. Jeremy Biesanz, who led a team of researchers from the University of British Columbia, said: "Many important decisions are made after very brief encounters -- which employee to hire, which person to date, which student to accept". Although our first impressions are generally accurate, it is necessary for us to recognize where they may be not good enough. The researchers arranged for two groups of more than 100 people to meet in a meeting. Much like speed-dating, the volunteers spoke to everyone in their group for three minutes each. At the end of each three-minute chat, they were asked to rate each other's personalities, and how well they thought their impressions "would _ someone who knows this person very well". To find out what the person was "really" like, the scientists had his friends and family fill out his personality reports. Generally speaking, the more confident the volunteers felt in accurately rating another's personality, the closer their ratings were to those of the other person's friends and family, the researchers said. However, the participants with the highest accuracy were those who rated themselves moderately accurate -- those highly confident of their judgment were less successful. The scientists concluded that, although we know people are different from each other, a good judge of character knows that in many ways people are mostly alike. For example, almost everyone would prefer being kind to being unfriendly. Therefore, while first impressions can be generally accurate, they are not conclusive in working out whether somebody really is "better" than someone else. The volunteers joined a meeting which was _ .

A. interesting
B. complex
C. serious

As Michael put each finger on the white laces of the football like his dad had shown him he thought about his school trip to the zoo tomorrow. He could not wait to get to the zoo and most of all could not wait to see his favorite animal, the lion. Aiming the football at the tire swing that hung in his back yard, he remembered the second thing his dad had taught him about throwing a football which was making sure his shoulder and the football were in a straight line before he threw it. He watched the football sail toward the tire, right as his mom called him in for dinner. His mom had made his favorite food, hotdogs. He sat in the kitchen and watched as ketchup fell on to his plate as he ate his hotdog. His mom told him that in order to get his after dinner treat he would have to eat his corn, carrots, and drink all of his milk too. That night as his mom tucked him in to bed he starred out the window and wondered if the lions at the zoo were looking up at the moon too. Michael, wondered if his best friends Joe, Nick, and Ryan were as excited as he was about going to the zoo the next day. He closed his eyes and went to sleep. The next day he hopped from one foot to the other as his class lined up to get on the bus that would take him to the zoo. On the bus he sat with Ryan. The bus driver started the engine and turned the big steering wheel leading them out on to the road. Finally, at the zoo Michael began to imagine how cool it would be to finally get to see the lion cage. First his class went to see the monkeys and then headed over to see the long necked giraffes. As their teacher announced that they would then be going to see the elephants, we wondered if he would ever get to see the lions. Finally after learning about the elephants it was time to see the lions. The lion stood on a huge rock and swung its long tail from side to side. The lion licked his lips with its long pink tongue and Michael wondered if it was thinking about having a class full of kids for its lunch. Who did Michael sit with on the bus?

The crash of the thermos caused the host,with a box of sugar cubes in his hand,to rush back from the inner room.He looked foolishly at the steaming floor and blurted out. "It doesn't matter! It doesn't matter!'' The father started to say something.Then he said in a low voice,"Sorry I touched it and it fell." "It doesn't matter,"the host said. Later,when they left the house,the daughter said,"Daddy,did you touch it?'' "No.But it stood so close to me." "But you didn't touch it.I saw your reflection in the window .You were sitting perfectly still." The father laughed."Then how would you explain the cause of its fall?" "The thermos fell by itself , The floor is uneven. It wasn't steady when Mr. Li put it there. Daddy,why did you say that?" "That won't do,girl.It sounds more acceptable when I say I knocked it down.There are things which people accept less true it sounds."

Worrying about how you'll perform on a math test may actually contribute to a lower test score, US researchers said on Saturday. Math anxiety--feelings of dread and fear and avoiding math--can weaken the brain's limited amount of working capacity, a resource needed to calculate difficult math problems, said Mark Ashcrafi, a psychologist at the University of Nevada Las Vegas who studies the problem. "It turns out that math anxiety occupies a person's working memory," said Ashcraft, who spoke at the annual meeting of the American Association for the Advancement of Science in San Francisco. Ashcraft said while easy math tasks such as addition require only a small part of a person's working memory, harder calculations require much more. Worrying about math takes up a large part of a person's working memory stores as well, _ disaster for the anxious student who is taking a high-stakes test . Stress about how one does on tests like college entrance exams can make even good math students choke. "All of a sudden they start looking for the short cuts," said University of Chicago researcher Sian Beilock. Although test preparation classes can help students get over this anxiety, they are limited to students whose families can afford them. Finally, she said, "It may not be wise to rely completely on scores to predict who will succeed." While the causes of math anxiety are unknown, Ashcraft said, "People who manage to get over math anxiety have completely normal math ability." What can we learn from the text?
Choices:
A. The causes of math anxiety have already been found.
B. All of the students attend test preparation classes.
C. Math anxiety weakens working memory needed to do math.
D. Few measures can be taken to get rid of math anxiety. | C |

Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries built the church in 1791. It was the start of a special kind of neighborhood: the Mission District. The area is a place with a long and varied history. One community member says that it's important for people to understand the many levels of history in the neighborhood. He feels that _ is a big part of understanding what it means to be a real San Franciscan. One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. It's easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music! Juan Pedro Gaffney, the director of the Spanish Choir of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively. But it isn't just its music that's colorful and lively. Its art is full of life as well. The local art community stays close to the area's culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals . Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, they're something the community likes. Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. "People see that they're not so different from each other," says one artist. "There are a lot of things that bind the immigrants through culture and tradition." The author shows the multi-culture of the Mission District from the aspects of _ .

Walking down any of Shanghai's main shopping streets this week, newcomers might think the locals have been celebrating Christmas for centuries. Christmas may not be a customary holiday in China, but businessmen in Shanghai know it will bring something more valuable than tradition: people are willing to spend money. Most Chinese may feel little connection with the Christmas celebration, but with most shops offering discount , the message couldn't be clearer-- it is the season to part with one's hard-earned cash. Much of that marketing drive is directed towards thousands of foreigners and foreign companies that call Shanghai home. But for Shanghai's 13 million locals, regardless of personal interest, there seems no avoiding the season's commercial greetings. Along some major roads, nearly every shop window displays some symbols to the holiday: a man-made fir tree with lights, or a snowman. With an increasing number of westerners arriving in the city for work, young Shanghainese, eager to keep pace with the latest western fashions, have begun to show their interest in Christmas. But some people still don't think Christmas is an important festival in China. At least it is less important than the New Year and China's Spring Festival. Which of the following statements is TRUE?
Choices:
A. Christmas is the season people will hold their hard-earned money tightly.
B. Most Chinese people think they have something to do with Christmas.
C. Christmas is the season for common people to earn money.

It is probably the strangest sport anyone has ever invented.And at first sight,it looks like the easiest.Competitors have to do two things.The first is to stand still.The second is to place their hands anywhere on the body of a car,and keep it there. This is where things start getting difficult.Lots of people are doing the same thing.And the winner of the "handathon" contest is the person who can carry on doing it for the longest time.That person gets to own the car. It still seems to be an easy thing to do.At the beginning it is.Anyone can stand still.But when the contest has been going for four or five days,standing still seems like the most difficult job in the world.And keeping the hand in place over this time becomes an act of serious attention.After a few days,the hand seems to belong to someone else--someone who wants to go home and get some sleep. Competitors are allowed to take a five-minute break every hour to eat,drink or do whatever else is necessary.No one is allowed to lean on the car for support.Winners need to be able to show great powers of attention.They also need to be able to develop special skills. Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter.Entrants in the Longview handathon certainly don't seem to do much preparation.Most say they will prepare by "getting lots of sleep".Others say they will "eat healthy food" or "pray for success".The whole event gives ordinary people the chance to do something interesting and win something in the end. Handathons are competitions,but there is little rivalry between competitors.They help each other out and keep each other's spirits up.People who drop out early return with food,drink and encouragement. Why is handathon popular?

A. Someone can win with special training.
B. It doesn't need to make any preparation.

Wealth is what you accumulate ,not what you spend.If you make $1 million a year and spend $1 million,you're not getting wealthier,you're just living high. The most successful accumulators of wealth spend less than they can afford on houses,cars,vacations and entertainment.Why? Because these things offer little or no return.The wealthy would rather put their money into investments or their businesses.It's an attitude. Millionaires understand that when you buy an expensive house,you buy an expensive life-style too.Your property taxes ,insurance,and the prices of nearby services tend to be higher.

As Paul, a bartender, was removing the restraining wire from a bottle of champagne produced and bottled by Winery, Inc., the plastic stopper suddenly shot out of the bottle. The stopper struck and injured Paul's eye. Paul had opened other bottles of champagne, and occasionally the stoppers had shot out with great force, but Paul had not been injured.Paul has brought an action against Winery, Inc., alleging that the bottle that caused his injury was defective and unreasonably dangerous because its label did not warn that the stopper might suddenly shoot out during opening. The state has merged contributory negligence and unreasonable assumption of risk into a pure comparative fault system that is applied in strict products liability actions. If the jury finds that the bottle was defective and unreasonably dangerous because it lacked a warning, will Paul recover a judgment in his favor?
Choices:
A. No, if the jury finds that a legally sufficient warning would not have prevented Paul's injury.
B. No, if a reasonable bartender would have realized that a stopper could eject from the bottle and hit his eye.
C. Yes, with damages reduced by the percentage of any contributory fault on Paul's part.
D. Yes, with no reduction in damages, because foreseeable lack of caution is the reason for requiring a warning. | A |

Eleven top universities are joining the Open University to launch free Internet courses. King's College London, along with the Universities of Birmingham, Bristol, Cardiff, East Anglia, Exeter, Lancaster, Leeds, Southampton, St Andrews and Warwick, has partnered with FutureLearn, a company set up by the Open University that will offer free and non-credit bearing courses to Internet-users around the world. The courses are modeled on the US phenomenon "Massive open online courses" ( Moocs ), which have attracted millions of users around the world and are especially popular in emerging economies. FutureLearn will improve UK institutions for international students, said Prof Martin Bean, voice-chancellor of the Open University. "At the moment, foreign students' _ of UK Universities is: wonderful history, great tradition, really good teaching, but a bit boring." Leeds University says the partnership will benefit students studying on campus. "Students will have access to a rich set of resources from both Leeds and our partners. They can also broaden their education beyond their main subject areas." The UK higher education industry stands among the top five export earners for Britain Moocs have grown rapidly in the US over the past year, with two providers leading the field. Coursera offers courses from 33 Universities, including Princeton, Brown, Columbia and Duke, and has reached more than 1.7 million users, EdX, a nonprofit start-up from Harvard and the Massachusetts Institute of Technology courses this autumn. Simon Nelson, one of the key architects of BBC Online, will head FutureLearn as launch CEO. "It's really meaningful for these universities to come together -we'll punch much harder collectively than any other university will individually," he said. Partner Institutions will be responsible for their own content while the OU, which has been providing distance-learning courses since 1971, will assist with course delivery and infrastructure. Details of further universities will be revealed next year, as will the courses on offer. We can learn from the passage that _

In the U.S.,the public has tended to believe that all motorcycles are ridden by wild,irresponsible lawless young men. There are several things about motorcycling that the average citizen dislikes.A cyclist's appearance has something to do with this dislike.Motorcyclists frequency look dirty;in fact,they are dirty.0n the road there is little to protect them from mud,crushed insects and bird droppings.For practical reasons they are often dressed in old clothing which looks much less respectable than the clothing of people who ride in cars.For the same reason motorcyclists usually wear dark color1s.Perhaps this helps to explain why they are sometimes suspected of having evil natures. In old plays of long ago,evil characters usually wore black. In cowboy movies the"bad guys"usually wear black hats while the"good guys"wear lighter color1s.Something else about their appearance makes an unfavorable impression. In their practical,protective clothing they look very much like the men on military motorcycles in the movies of World War II--cruel enemies who roared into peaceful villages filling people's hearts with fear. Probably the machine itself also produces anger and fear. Motorcycles are noisy,though some big trucks are even noisier.But trucks are big and carry heavy loads;they are accepted(if not really welcomed)because they perform a needed service,making America move.Motorcycles,on the other hand,make all unpleasant noise just to give their riders pleasure.That is what is commonly thought.In the woods motorcycles,frighten animals.Roaring along quiet streets, they wake sleeping families and make babies cry. Of course the danger of motorcycling,also helps account for many people's low opinion of the sport.Its defenders, however,claim that careful cyclists are in less danger than commonly behaved. A cyclist must drive as if everybody around him wanted to kill him.He must pay careful attention to his driving.From that point of view,a man on a motorcycle is safer than,a man in a car.

More and more schools are being designed and used in ways that are friendly to the environment. These so-called green schools use less energy, cost less to run and are good for students. The newly renovated Sidwell Friends Middle School in the District has been awarded the highest rating by the U.S. Green Building Council for having a positive impact on the environment-a rare honor. Soon the school will treat and re-use its wastewater, saving hundreds of thousands of gallons of water per year. The recycled water from sinks and toilets, which can't be used for drinking, will be color1ed blue, "so we know it's recycled, just in case it gets into the water fountains -not that it would," joked Emily Bernstein, 14, a Sidwell student and building tour guide. Water fountains will still use fresh city water. Sidwell students are studying the building itself in science classes to help them learn first-hand the positive impact of green buildings. It's affecting how they view the world around them. "If you see a [building] being torn down, you think, 'They're going to fill up a whole landfill with that,'" said Matthew Malone, 13. In Prince George's County, Suitland Elementary has been so successful that another green school is being planned, in Laurel, for the 2008-09 school year. At Suitland, a garden courtyard collects and uses rainwater; the roof is angled away from the sun to keep it cool; and skylights and tall windows let in lots of natural light. "You don't have to switch on the light switch all the time," said Rupert McCave, the county official guiding these projects. Green schools tend to be sunnier and more _ than older buildings. In fact, a study done inprefix = st1 /Washingtonstate showed that students at green schools performed better and were absent less. From Matthew Malone's words, we can see that_.

mmlu | Question:
A rabbit is running into its hole. You may ask, "What happened?" Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is danger. The rabbit has told them something without making a sound. It has given them a signal. Many other animals use this kind of language. When a bee found some food, it goes back to his home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is. Some animals say things by making sounds. A dog barks, for example, when a stranger comes near. A cat purrs when pleased. Some birds make several different sounds, each with its own meaning. But human beings have something that no animals have --- a large number of words about things, actions, feelings or ideas. We are able to give each other information, to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things what have happened, or send messages to people far away. No animals can do this. No animals has the wonderful power of language. No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language. People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example, contains four or five hundred thousand words. But we do not know all these. The words we know are called vocabulary.

Next time you raise an eyebrow at the views of your partner, friend, sibling or colleague, remember they could be helping to make you smarter. New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members, bright mates and intellectually stretching careers. The study challenges the commonly held belief that intelligence is static by the age of about 18. Current scientific consensus suggests that intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a partial role up to this age. After this point, IQ scores stabilize . But James Flynn, professor of political studies and psychology at the University of Otago in New Zealand, argues that people can "upgrade" their own intelligence throughout their lives. He believes intellectual stimulation from others is crucial as the "brain seems to be rather like a muscle - the more you use it, the stronger it gets". However, the opposite is also true - so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels fall as a result. He found the "understanding quality" of a family changes the IQs of all members, especially children. It can "lift" or hold back, depending on the "gap between their brightness and that of their siblings and parents". A bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage, compared to a similar child with equally bright siblings. However, children with a low IQ could gain six to eight points by having brighter siblings and special educational treatment to help pull them up.

Late that afternoon I took the train back to Sydney . There I found another surprise waiting for me . My room at the hotel had been given to somebody else and they had no room for me. Harkin had known my travel plans and had planned everything . How could he have booked the room only for three days ? There was nothing to be done but to find another hotel. The waiters were happy to find me a new hotel , and when I said that I was happy to stay at the airport , thinking it might be cheaper than staying in the city , they suggested the Holiday Inn at the airport . There was one small matter : the room rate was $ 300 per night . The best hotel in Katoomba had wanted only $ 145 . I asked if there was anything cheaper they might suggest but they warned that most hotels would already be full by this time. The hotel was far from the train station , so I had to take a taxi , at $ 25 . On the way to the Holiday Inn , we passed a hotel just two blocks from the Holiday Inn that advertised a room rate of $ 104 . At the desk I asked if their room rate could go down a lot . " No , this is a 4-star hotel," the waiter told me . " In that case ," I replied , " I'll just walk the two blocks to the cheap hotel."

A famous building in New York City is turning 100 years old. A year-long celebration is planned for Grand Central Terminal, which is usually called Grand Central station, the sixth most-visited place in the world. The huge building has not changed much since it opened in February, 1913. About 750,000 people pass through Grand Central every day. Some just come to look at it, others to visit the stores. But most are there to catch the trains that enter and leave from the station. It is the largest train station in the world. There are 67 train tracks, all of them underground. The main part of the building has large, arched windows, a jeweled four-sided clock and ticket windows. Grand Central has been seen in many movies through the years. Dan Brucker is with the New York Transit Authority, which operates the station. Dan Brucker has worked for the transit authority at Grand Central for 30 years. In all those years, he has not lost his interest in the building. Justin Ferate, a historian, has been giving tours of Grand Central Station for 30 years. He says the station was designed to make travel a pleasure. "Why people don't run into each other in Grand Central is simple: each block of stone in Grand Central is the length of your leg. Each block of stone in Grand Central is the length of your arm. Each block of stone is a different color, so it's a checkerboard, based on you." A ten-year-long fight against plans to build a huge office building over Grand Central in 1968 helped create the modern preservation movement. Now, no one would think of changing the beauty of the station. Which of the following statements about the station is WRONG?
Choices:
A. It's in New York City.
B. It's one of the most-visited places in the world.
C. It's the largest train station in the world.
D. It has been changed much over the years. | D |

When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles. Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song. But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: "Songs move like cultural communication from one population to another, causing all males to change their song to a new version." Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia. Most of the new songs contain material from the previous year mixed with something new. " It would be like getting an old Beatles song together with U2," she said. " Occasionally they completely throw the current song out of the window and start singing a completely new song". Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: " we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex." What is the main idea of the text?
Choices:
A. The humpback whale likes to hear Lady Gaga's songs.
B. The humpback whale's tunes sound like Lady Gaga.
C. Lady Gaga's new single gained worldwide popularity.
D. The songs of humpback whales can spread globally. | D |

If your mother told you to eat carrots so you'd be able to see in the dark, she was right. It turns out that feeding kids carrots is just one of a number of things to keep eyes healthy. Other things include regular eye exams, and sunglasses or hats are also very helpful, experts say. While eye disease is sometimes hereditary , some are still preventable , said Dr. Ron Weber, an Atlanta-based ophthalmologist. For example, nearsightedness, "not only has a genetic component but is also influenced by how kids use their eyes during childhood," he told Reuters Health by phone. He said that extended close work, such as reading, has long been thought to cause nearsightedness. Recent support has come from a study in which people with a higher level of education were more likely to have nearsightedness, because they spend more time reading or working on computers. Another study showed that children who spend more time outdoors are less likely to become nearsighted. But these findings don't mean kids should be stopped from reading or working on the computer. Instead, Weber suggests, make sure a child's environment is bright enough while they are doing close work. Parents should also help kids get into the habit of holding their reading material at the perfect distance - about 18 to 22 inches, he said. Finally, taking a break every five minutes or so, to let the eyes relax and focus on an object in the distance, will also help. One of the most important things a parent can do to help _ eye disease and vision problems is to make sure their child gets regular eye exams, beginning early in life. "The majority of vision problems in children are preventable and treatable," said Dr. Ida Chung. What does the writer want to tell us in the passage?
Choices:
A. It is important to keep your eyes healthy.
B. People seldom pay attention to eye health.
C. It is necessary to give your kids carrots.
D. All the eye disease are hereditary. | A |

mmlu | Question:
We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it is an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers. Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say "Ugh!" and run away. Workers must first dry and then roast the beans. This removes the bitter taste. The word "chocolate" comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink. When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion. In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better. Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and of course an ice cream sundae with hot fudge sauce. According to the passage which of the following statements is TRUE?
Choices:
A. Nobody had the idea of adding sugar until the sixteenth century.
B. The word "chocolate" comes from a Mexican word.
C. The beans taste so bitter that even the monkeys like them.
D. Workers must dry and roast the beans to remove the bitter taste. | D |

Passage 1 The Information Highway is the road that links computer users to a large number of on-line services: the Web,e-mail,and software,to mention just a few. Not long ago,the Information Highway was a new road,with not many users. Now,everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems,forcing the system to close down for repair. Naturally,accidents will happen on such a crowded road,and usually victims are some files,gone forever. Then,of course,there' s Mr. Cool,with his new broad-band connection,who speeds down the highway faster than most of us can go. But don' t trick yourself:he pays for that speeding.
