1、Fermi Problem
On 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、Intelligent Machines
1. Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson's disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is author of the successful book The Age of Intelligent Machines and is one of the world's best computer research scientists. He is researching the possibilities.
2. Kurzweil gets computers to recognize voices. An example of this is Ramona; the virtual (虚拟的) hostess of Kurzweil's homepage, who is programmed to understand what you say. Visitors to the site can have their conversations with her, and Ramona also dances and sings.
3. Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on in the visible world", he explains. Blind people will use a visual sensor (探测器) which will probably be built into a pair of sunglasses. This sensor will describe to the person everything it sees.
4. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to trans late into other languages, so even people without hearing problems are likely to be interested in using it.
5. But it is not just about helping people with disabilities. Looking further into the future, Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won't be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever.
Ray Kurzweil works with computers to help people ____.
【单选题】

A.what you say

B.a pair of sunglasses

C.the listening machine

D.a visual sensor

E.who have disabilities

F.living forever in a computer

正确答案:E

答案解析:本题难度不大，是针对第三段的开头的主旨句出题，考生可根据题干提示词回到文章定位，找到这个主旨句，Kurzweil uses this technology to help people with physical disabilities，再结合选项，不难发现，E项who have physical disabilities就是对这个主旨句的近义改写，是答案。

3、Britain's Solo Sailor
Ellen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money for three years to buy her first small sailing boat. When she was 18, she sailed alone around Britain and won the "Young Sailor of the Year" award.
Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors and she was given a very warm welcome when she returned.
Ambition and determination have always been a big part of Ellen's personality. When she was younger, she lived in a kind of hut (棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race. Then she took a one - way ticket to France, bought a tiny seven meter Class Mini yacht (游艇), slept under it while she was repairing it, and then she raced it 4,000 kilometres across the Atlantic in 1997, alone for 33 days.
Ellen has to learn many things, because sailing single - handed means that she has to be her own captain, electrician, sailmaker, engineer, doctor, journalist, cameraman and cooker, She also has to be very fit, and because of the dangers of sleeping for long periods of time she's in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time.
And she needs courage. Once, in the middle of the ocean, she had to climb the mast (桅杆) of a boat to repair the sails at four o'clock in the morning, with 100 kph winds blowing around her. It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It's hard to describe how it feels to be up there. It's like trying to hold onto a big pole, which for me is just too big to get my arms around, with someone kicking you all the time and trying to shake you off".
But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean and having the chance to live this. I just feel lucky to be here."
According to paragraph 4, which of the following statements is NOT true? ____ 【单选题】

A.She has to learn to repair sails.

B.She has to be her own teacher.

C.She has to be very fit.

D.She has trained herself to sleep for about 20 minutes at a time.

正确答案:B

答案解析:本题是判断题，有一定难度，选项的干扰较大，需要确定好文章里sailmaker的意思，需要紧扣文章原意。选项里A，B干扰较大，因为，C，D很明显是文章里明确提到的，可以排除。第四段谈到，“Ellen必须学会许多事情，因为单独航行意味着她必须是自己的船长、电工、修帆工……”Sailmaker是指“修船工”，所以A的意思和原文是一致的，可以排除。Captain，船长，不是教师，所以B是错误的，答案是B。

4、He predicted that an earthquake was imminent.【单选题】

A.foretold

B.proposed

C.promised

D.identified

正确答案:A

答案解析:predicted和foretold都是“预言”的意思；proposed：提议；promised:承诺；indentified:证明、确认。

5、Indian's Names
Each Indian was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.
The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a Horse. So an Indian's name told his record or described the kind of man he was.
A man was given many chances to improve his name, however, if in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelve names, all good and each better than the last.
An Indian's names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.
Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three or four times when this happened. It is the rarest honor for a person -the honor of assuming his father's name.
An Indian could be given the second name by____.【单选题】

A.his father

B.the enemy

C.the chief of the tribe

D.his childhood friends

正确答案:D

答案解析:birth name是出生时就取的，而且应该保留直到大了以后可以自己赢得一个名字。但是儿时的玩伴会给他一个a name of their own，因此选D。

6、The courageous boy has been the subject of massive media coverage.【单选题】

7、Wealth
Among the more colorful characters of Leadville's golden age were H. AW. Tabor and his second wife, Elizabeth McCourt, better known as "Baby Doe". Their history is fast becoming one of the legends of the Old West. Horace Austin school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here. " he said.
As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco. It was his custom to "grubstake" prospective miners, in other words, to supply them with food and supplies, or "grub", while they looked for ore, in return for which he would get a share in the mine if one was discovered. He did this for a number of years, but no one that he aided ever found anything of value.
Finally one day in the year 1878, so the story goes, two miners came in and asked for "grub". Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. "Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in gave Tabor a one-third interest in their findings. They picked a barren place on the mountainside and began to dig, After nine days they struck a rich vein of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine," made l,300,000 for Tabor in return for his $17 investment.
Later Tabor bought the Matchless Mine on another barren hillside just outside the town for$117,000. This turned out to be even more fabulous than the Pittsburgh, yielding $35,000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor, and later became lieutenant governor of the state.
The word "grubstake" in paragraph 2 means_____.【单选题】

A.to supply miners with food and supplies

B.to open a general store

C.to do one's contribution to the development of the mine

D.to supply miners with food and supplies and in return get a share in the mine, if one was discovered

正确答案:D

答案解析:第2段中grubstake的词义与D所述内容是相同的，即“供给探矿者资金、衣物、食品以及其他物品”。

8、J. K. Rowling
Like that of her own character, Harry Potter, J. K. Rowling's life has the luster of a fairy tale. Divorced, living on public assistance in a tiny Edinburgh flat with her infant daughter, Rowling wrote Harry Potter and the Sorcerer's Stone at a table in a cafe during her daughter's naps and it was Harry Potter that rescued her.
Rowling remembers that she always wanted to write and that the first story she actually wrote down, when she was five or six, was a story about a rabbit called Rabbit. Many of her favorite memories center around _____ .
On a particularly long train ride from Manchester to London in the summer of 1990, the idea came to her of a boy who is a wizard and doesn't know it. He attends a school for wizardry -she could see him very plainly in her mind. By the time the train pulled into King's Cross Station four hours later, many of the characters and the early stages of the plot were fully formed in her head. The story took further shape as she continued working on it in pubs and cafes over her lunch hours.
Rowling was working as a French teacher when she heard that her book about the boy wizard had been accepted for publication. Harry Potter and the Philosopher's Stone was published in June1997 and achieved almost instant success. With the publication of the American edition, retitled Harry Potter and the Sorcerer's Stone, in 1998, Rowling's books continued to make publishing history. Harry Potter climbed to the top of all the bestseller lists for children's and adult books. In Britain a separate edition of the first book appeared with a more "adult" dust jacket so that grown-ups reading it on trains and subways would not have to hide their copy behind a newspaper.
J. K. Rowling lives in Edinburgh, Scotland, with her daughter Jessica and continues to work on writing the seven-book story of Harry Potter.
【单选题】

A.would not have to hide their copy behind a newspaper.

B.With the publication of the American edition,

C.By the time the train pulled into King's Cross Station

D.Young people prefer to read stories about cities.

E.enjoying the fantastic adventure stories.

F.during her daughter's naps

正确答案:E

答案解析:根据前文“她记得她在六、七岁时写的第一个关于兔子的故事，她的美好记忆都围绕着……”，后面一定是奇妙的冒险故事，所以选E。

9、The State of Marriage Today
Is there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times and extramarital affairs will be even more common than they are now.
But what are the reasons for this, and is the picture really so gloomy? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands as they usually didn't have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don't feel that they need to stay in a failing marriage.
In answer to the second question, the outlook may not be as pessimistic as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now cohabit and don't bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages.
So is marriage really an outdated institution? The fact that most people still get married indicates that it isn't. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!
Why may the outlook of marriage not be as gloomy as it appears?【单选题】

A.Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 50% of the marriages continue to exist.

D.The statistics of divorce is not quite true.

正确答案:A

答案解析:从第3段里可以了解到离婚率并没有下降而是上升了，因此B选项不对。而C选项与第3段里“In fact，more than 50% of first marriages survive”所说不符，该选项没有提到是第一次婚姻。同样，D选项在文中也没有说到，文中第3段的最后一句只是说统计数据具有欺骗性，而没有说数据失实。

10、African wild dog
Finding 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.
The remaining lions will die out within decades.
