1、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. Others will die out for lack of food. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. _____. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:A

答案解析:选项A中的ecological recovery与前面一句中的recognize相呼应，提示选项A的句子是前面句子的后续句。

2、Intelligent Machines1. 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.People without hearing problems may also be interested in using ____.【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:C

答案解析:本题难度不大，针对第四段最后一句出题，考生可根据题干提示词回到文章定位，找到第四段最后一句：The listening machine will also be able to translate into other languages, so even people without hearing problems are likely to be interested in using it。 回来再看选项，很明显，答案是C。

3、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.Ties were first worn by the Croatian soldiers________.【单选题】

A.they were workmen

B.they were members of different organizations

C.hospital doctors stop wearing ties

D.who does not always wear a tie

E.who served as mercenaries in many conflicts in the 18th century

F.who does not want to live like a king

正确答案:E

答案解析:根据题干中的线索词Croatian soldiers可定位到第三段第二句：Soldiers from Croatia, in Eastern Europe, served as mercenaries（雇佣军）in various conflicts in the 17th century. E选项who served as mercenaries in many conflicts in the 17th century是原句的同义复现，故E为正确答案。

4、Money or Friendship or Both1. Friends and money don\'t mix. It\'s a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don\'t lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don\'t need it? Are you willing to write off that amount if it\'s not returned? If your answers are negative, do yourself a favor and say "no".3. Let\'s assume you can\'t stand saying "no" to your friend because you don\'t want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:Amount of the loan.Date of the loan.Time of repayment.Amount of interest (if any).Lender\'s and borrower\'s signature.This will at least keep the borrower from forgetting the loan so easily, If your friend\'s loan is past due, it\'s important that you ask him－and it\'s actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.4. You can send him a friendly reminder via E - mail. Tell him something like "I\'m going over my bank account and I\'m just wondering when we\'ll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.5. After asking two or three times, you might have to write it off. That\'s what happens. If he just doesn\'t have the money or is unwilling, then what kind of friend is that?Before you lend money to your friend ____.【单选题】

A.you can remind your friend of it via E - mail

B.you can lend more money to him or her

C.you must get to know why he or she needs that money

D.if you should lend money to your friend

E.you can call the police to settle the issue

F.there is no need to maintain a friendly relation with him or her

正确答案:C

答案解析:本题难度不大，答案依据不难找到。答案依据在第二段。读懂题干意思后，认真阅读第二段。第二段第二句话，Think about why this person needs to borrow in the first place，是主要依据，再回来看选项，C项符合文章句意，是答案。

7、A New Doctors\' DilemmaWhen Christian Barnard, a South African doctor, performed the first human heart transplant in1967, the result was a worldwide moral debate on the ethics of transplanting organs. Hearts were not the first human organs to be transplanted but, in this case, if a donor gave his or her heart, he or she would obviously and necessarily die (or be dead). Kidney transplants, which were already quite common in 1967, often involved the transfer of a single kidney from a close living relative. The chances of survival of the donor were somewhat diminished because he now had only one kidney and if that kidney were affected by disease, he would not have a healthy kidney in reserve. Nevertheless, the donor would certainly not necessarily die.Undoubtedly, another reason why the first heart transplant was so controversial was the fact that we associate so many personality traits with the heart. Questions were asked of the type: "If a person had a different heart, would he still be the same person?", or "If doctors needed a dying person\'s heart, would they tend to declare him dead prematurely?", and so on.Today, not only hearts and kidneys, but also such extremely delicate organs as lungs and livers, are transplanted. These developments have led to a far higher or proportion of successful operations and this, in turn, has led to greater demand for transplants. At the same time, many of the original moral questions surrounding heart transplants have been almost forgotten.However, as a result of the heavy demand for organs, a new moral dilemma has emerged. For example, in the United States there are many people who would survive iflungs were available for transplanting. In fact, about 80% of them die before a suitable donor is found. In these circumstances who would decide if a donor were found whose lungs were equally suitable for two potential recipients?This problem is made worse by the fact that many patients, or their families, become desperate to find a donor. Some succeed in publicizing their situation in newspapers, to politicians or on television. Sometimes, as a result, suitable donors are found. But what would happen if another patient needed the organ more than the one who got the publicity? Who would decide if the other patient should get the organ? Would it be the doctors? Or the donor? Or the family who got the publicity? If such a dilemma developed it would be very difficult to resolve and it would be a matter of life or death to the patients involved.Which of the following is true?【单选题】

A.Kidney transplant operations were not corumon until 1967.

B.Kidney s for transplant operations had to come from dead people in 1967.

C.Kidney transplant operations were performed before heart transplant operations.

D.Heart transplant operations were as common as kidney transplant operations.

10、Shopping at Second - hand Clothing StoresWhen 33 years old Pete Barth was in college, shopping at second - hand clothing stores was just something he did－"like changing the tires on his car." He looked at his budget and decided he could save a lot of money by shopping for clothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons for shopping for second - hand clothing. Some people, like him, shop to save money. Some shop for a crazy - looking shirt. And some shop as a means of conserving energy and helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, for her, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said: "Also, why pay 30 dollars for a new coat when you can get another one for a lot less?"Akins said that the SA has shops all over the US－"some as big as department stores". All of the clothes are donated (捐赠), and when they have a surplus (盈余), they\'ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes for only 5 or 10 dollars.Julia Stocum, 22, points out, however, that the huge amount of second - hand clothing in the US is the result of American wastefulness."I\'d say that second - hand stores are the result of our wasteful, materialistic culture," said Slocum, who works for a pro - conservation organization, the center of a New American Dream. "Thrift shops prevent waste from going to landfills (垃圾填埋场), They give clothing a second life and provide cheaper clothing for those who can\'t afford to buy new ones and generate (创造) income for charities. They also provide a way for the wealthy and middle classes to shed (摆脱) the guilt for their level of consumption."Thrift shops can do everything EXCEPT ____【单选题】

A.give clothing a second life.

B.generate income for charities.

C.provide cheaper clothes for the poor.

D.stop rich people from wasting money.

正确答案:D

答案解析:本题有一定难度，需要认真阅读文章，答案依据在文章最后一段。最后一段谈到，旧货店给了服装二次生命，给那些买不起新衣服的人提供便宜衣服，还把一些收入捐给慈善机构，但没有提到阻止富人浪费钱，所以答案是D。
