1、Fermi ProblemOn a Monday morning in July, the world\'s first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi and his team stood. After a mental calculation, Fermi announced to his team that the bomb\'s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi\'s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi\'s death in 1954, no physicist has been at once a master experimentalist and a leading theoretician.Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven\'t the remotest notion of the answer, and you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s or books, you can come close to the exact solution.Suppose you want to determine Earth\'s circumference without looking it up. Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours. Three hours is one-eighth of a day, and a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions. It doesn\'t matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles. Looking up the answer, or letting someone else find it deprives you of the pleasure and pride that accompany creativity, and deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.Fermi problem is to develop the talent of breaking a seemingly unanswerable problem into sub-problems and finding the solution to it, which is a typical Fermi problem.【单选题】

2、G8 SummitLeaders of the Group of Eight Major Industrialized Nations (G8) will meet in Scotland in July this year. Representatives from China, India, Mexico, South Africa and Brazil have also been invited. Here\'s what the G8 leaders want from the meeting.British Prime Minister Tony Blair wants the G8 to cancel debt to the world\'s poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers and removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests. On climate change, Blair wants concerted (共同的) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn\'t like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol(《京都议定书》). Although the US is the world\'s biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem.French President Jacques Chirac supports Blair on Africa and climate change. He is determined to get the US to sign the climate change deal.German Chancellor Gerhard Schroder remains doubtful of Blair\'s Africa proposals. Schroder\'s officials have dismissed the notion that money will solve Africa\'s problems as"old thinking". Berlin says that African states should only receive extra money if they can prove they\'ve solved the corruption problem.Russian President Vladimir Putin was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Putin intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet Republics of Georgia, Uzbekistan, Tajikistan and Moldova.Japanese Prime Minister Junichiro Koizumi\'s priorities are a seat on the UN Security Council, for which he will be lobbying (游说) at the summit. And he\'s concerned about the Democratic People\'s Republic of Korea\'s nuclear weapons programme.Chirac takes a stand similar to Blair’s on Africa and climate change.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:根据主语Chirac可以确定答案出自第四段。第四段第一句：French President Jacques Chirac supports Blair on Africa and climate change. （Chirac支持布莱尔对非洲和气候变化的看法及态度。）这与题干所表达的意思是一致的，故正确答案是A。

3、Why Is the Native Language Learnt So Well?How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty and inexact command. What accounts for this difference?Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, and right use of words and right structure. He drinks in all the words and expressions, which come to him in a flash, ever-bubbling spring. There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled.Finally, though a child\'s "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.Gestures and facial expressions may assist a child in mastering his native language.【单选题】

正确答案:A

答案解析:题干大意：手势和面部表情可能会对儿童掌握母语有帮助。利用答案线索词gestures和facial expressions，我们可以在第三段第二句中发现直接相关信息。该句说：儿童学习母语的另一个优势是可以接触各种情景的母语，而且还常伴随着正确的手势和面部表情。可见原句的说法与问题句一致，所以问题句“正确”。

4、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.There is a tension between babysitting and hurting.【单选题】
