2、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. This allowed scientists to gauge the pace and progress of the ecological recovery. 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. _____.【单选题】

3、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi\'s Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We\'ve been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."4. But it wasn\'t all so easy. For Denise, the worst part was waiting at the beginning. "After I\'d sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren\'t allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there\'s been no problem with the physical side of singing: "We didn\'t have to worry about that as we\'ve had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn\'t understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.Paragraph 2 ____【单选题】

A.Advice

B.Living the new life

C.The competition

D.Becoming famous

E.Their lives before

F.The difficult parts

正确答案:E

答案解析:本题的难度减弱，通读第二段后，回来看选项，找信息提示，可以发现，their lives before，讲的是她们成名前的生活，所以最佳答案是E。

4、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet and disease. Since 1957 a team of American researchers has monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential for the growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples.In the Western Electric study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.Why do researchers warn against taking large numbers of vitamin A pills?【单选题】

A.The pills are hard to swallow.

B.The pills contain a chemical that can be toxic in high doses.

C.The pills are expensive.

D.The pills cause lung cancer.

正确答案:B

答案解析:根据最后一段，“因为该药片包含一种化学成分，大剂量服用时有巨毒”，因此答案B。

5、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 ______.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 that 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.own

B.lend

C.owe

D.possess

正确答案:C

答案解析:A项和D项是近义词，所以可排除，空格所在的局部结构是：paying back the money they...（偿还他们……的钱），故C项为正确答案。

6、The company has the right to end his employment at any time.【单选题】

A.provide

7、The State of Marriage TodayIs 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 (婚外的) affairs will be even more common than they are now.But what are the reasons for this, and is the picture really so gloomy (黑暗的)? 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 (悲观的) 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 simply live together 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.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! (2011年)Why is the outlook of marriage not as hopeless as it appears?【单选题】

A.Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 60% of the marriages continue to exist.

D.The statistics of divorce is reliable.

正确答案:A

答案解析:细节考查题。题干问“前景似乎不像人们想的那么悲观的原因”。正确答案为A“很多人仍然想结婚”。离婚率没有下降而是上升了，故I3项与原文信息不符；选项C和D与原文内容不符。

8、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.Paragraph 3 ____【单选题】

A.A new pair of eyes

B.Computers that can communicate

C.Everlasting consciousness on a computer

D.Time to break off a friendship

E.An author and researcher

F.A new pair of ears

正确答案:A

答案解析:本题难度不大，考生只要认真阅读第三段，不难抓住本段的中心。这一段主要是说如何帮助盲人，这种“看得见的机器”能够使盲人描述他所看到的一切。A项A new pair of eyes，“一双新的眼睛”，可以概括本段内容，答案是A。

9、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 6 ________.【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:F

答案解析:第六段的主题句是第二句：The signs are not promising.这里the signs后边省略了of the future of ties。该句说明领带的前景不是很好。比如在后一句中讲到英国首相布莱尔等政治家经常在公共场合不再戴领带，这进一步说明了以后人们可能不再打领带。F选项Signs of a tieless era与其表达相符，故F为正确答案。

10、LanguageWhen one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of language is a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Language a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different relationship of words in a sentence. Anglo-Saxon(old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections come into conflict with word order,. there may be trouble for the users of the language, as we shall see later when we turn our attention to such maters as WHO or WHOM and ME or l. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The eighteenth century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write.Which of the following statements is not mentioned in the passage?【单选题】

A.It is generally believed that the year 1500 can be set as the beginning of the modern English language.

B.Some other languages had great influence on the English language at some stages of its development.

C.The English language has been and still in a state of relatively constant change.

D.Many classes or groups have contributed to the development of the English language.

正确答案:A

答案解析:根据文章的内容，选项A“普遍认为1500年是现代英语的起点”在文章中没有提及，故为正确答案。文章第2句说“The history of our been a history of constant change…. at times a slow, almost imperceptible change, at other times a violent collision between two languages. ”由此可以推断一些其他的语言对英语的发展有重大影响，选项B符合文章的意思。
