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.Then the fourth paragraph tells us how Fermi solved the problem of earth\'s circumference without looking up.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:第4段是为第2段和第3段的内容提供实际例子，即Fermi problem的实际运用，并不是Fermi本人运用Fermi解决问题的方法约略推算出地球的周长。由此可见，题干的说法是错误的。

2、Ceasing to Wear TiesIt\'s useless. It\'s dirty. It spreads disease. That\'s why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It\'s an interesting story, but it doesn\'t tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman\'s clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain\'s most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.Paragraph 4 ________.【单选题】

A.Origin of the tie

B.British ties

C.Uselessness of the tie

D.Old-fashioned ties

E.Role of the tie

F.Signs of a tieless era

正确答案:E

答案解析:第四段的主题句是第二句：The answer seems to be about identification.这里the answer后边省略了why people wear ties。该句说明人们戴领带是为了表明身份。这说明了领带在日常生活中所起的作用。E选项Role of the tie与其意思一致，故E为正确答案。

3、Making Yourself a Good RecordIf you are an American and you think you might need to borrow money someday, the best thing to do is to start early.That\'s because just as many employers want to hire only people with experience, banks and other creditors are usually reluctant to lend to those without a proven track record of paying back, on time, the money they have borrowed.But if you need experience just to get a start, how do you get that start in the first place?With a little help from your parents usually, while you are still financially dependent on them. It is easy to get a credit card or student loan when you are in college, because banks figure your parents will bail you out if you fail to pay.So just as students take on internships to build up their resumes, one s university time can be a good time to work on another important personal record: the credit reportCredit reports are a summary of one\'s personal credit history, gathered by a credit reporting agency, or CRA.Banks, and companies including hospitals, landlords and insurance companies-regularly report to the three main CRAs in the US on how their customers are doing at paying back the money they owe.Anyone with a "legitimate business need" has the right to order individuals\' reports from the CRAs. Potential creditors usually compile the information in the reports into a credit "score", ranking the level of creditworthiness. Lack of experience in borrowing in addition to a bad record of doing so, can result in a low score.Even if you are not considering taking out a loan for such a large purchase as a home or car, your credit report can be important to getting through life. Landlords often ask for the reports to judge whether a person can be trusted to pay the rent. Credit checks are necessary for getting a credit card, even for purchasing a mobile phone calling plan.People can obtain a copy of their own credit report, usually at a cost of around US$ 8-9. Some consumer organizations recommend doing this once a year to allow one to catch any mistakes ______have slipped into the records or, even worse, to find out whether any fraud has taken place. Though the system is controlled by laws meant to protect people\'s privacy, it isn\'t fool-proof. Sometimes people take out bad loads in others\' names, ruining their records.In a society addicted tocredit, that can be a disaster.【单选题】

A.these

B.what

C.that

D.those

正确答案:C

答案解析:空格所在的结构是跟在名词mistakes后面的定语从句，只有that可以引导定语从句。故C项为正确答案。

4、Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 and respond quickly to space station emergencies.The space agency released the first set of mission needs and requirements several days ago for me orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to and from the International Space Station.Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper and require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available for rescue missions by 2010. NASA says the craft should be able to transport injured or ill space station crew members to "definitive(决定性的) medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia and its seven member crew on February l, 2003.Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working for years on a successor to the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.The program\'s managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.U. S. President George W. Bush asked Congress for about US$1 billion for Space Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.The design of the orbiter indicates ____ .【单选题】

A.NASA\'s determination to continue space exploration

B.NASA\'s disadvantage in space technology

C.the great pressure from Congress on NASA

D.a heavy defeat for NASA

正确答案:A

答案解析:此题问的是设计这架航天飞机表明了什么？选项A的意思是“NASA继续探索太空的决心”。其他几个选项的意思均与原文不符，所以A为答案。

5、Stop Eating Too much"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent or grandparent. Often, it\'s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can\'t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.It\'s not that working class Americans don\'t want to eat healthy. It\'s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money for next year\'s Christmas presents.(2008年)What happened in the 1970s?【单选题】

A.The US government called on its people to reduce their weight.

B.Health experts persuaded restaurants to serve smaller portions.

C.The American waistline started to expand.

D.The United States produced more grain than needed.

正确答案:C

答案解析:题干问“20世纪70年代发生了什么”。参见文章第三段，其中提到：一位宾夕法尼亚州立大学营养学教授告诉《今日美国》，20世纪70年代餐馆给的饭菜的量开始增加，与此同时，美国人的腰围也开始增大。故正确答案为C。
