1、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let ____ of such a potential weapon. Undoubtedly several nations still have a few vials. And the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US and Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

2、The Only Way Is Up Think of a modem city and the first image that come to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities don\'t permit buildings to go above a certain height. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers. When people gather together in cities, they create a demand for land since cities are places where money is made, that demand can be met. And the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground that means building upwards. The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They had to be small enough for people on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, or home. Elisha Otis, a US inventor, was the man who brought us the lift or elevator, as he preferred to call it. However, most of the technology is very old lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine and develop the elevator brake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public confidence in the new invention. In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects and builders. A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that it would just be boring. Yet psychologists and others who study human behavior find lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts. "It breaks all the usual conventions about the bubble of personal space we carry around with us and you just can\'t choose to move away," says workplace psychologist, Gary Fitzgibbon. Being trapped in this setting can create different types of tensions, he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. Some stand close to the door. Others hide in the comers. Most people try and shrink into the background but some behave in a way that makes others notice them. There are a few people who just stand in a comer taking notes. Don\'t worry about them. They are probably from a university.The difficulty in constructing tall buildings in the 19th century lies in____.【单选题】

A.the shortage of money

B.the lack of a device to carry people upward

D.mountains taking up land space

3、Waste Not, Want Not1 Bob and Clara Darlington, who own and run a farm in the North of England, have always looked for new ways of making money out of the produce they grow. Their SUCCESS began when they established a shop on their farm, so that people could come and buy fresh vegetables directly from them.2 The business was an immediate SUCCESS, and soon scored top marks in a competition set up by the Farm Retail Association to find the best farm shop in the country. The Association\'s inspectors found the Darling tons\' shop offered excellent service and value for money as well as quality fruit and vegetable.3 Clara Darlington is a trained chef and, in addition to a range of home-grown foods and other local produce, she began offering a variety of prepared meals which she had made herself in the farmhouse kitchen. A small cafe alongside the farm shop was soon added, with everything that visitors could taste on the menu also being for sale in the shop.4 Clara admits that starting the business was expensive, and she has worked very hard, but maintains that if the product is good, the public recognize this and buy it. "I aim to offer the highest quality to our customers, whether they come in for a loaf of bread, or take a whole dinner-party menu. I take it as a compliment if people take home one of my dishes to serve to their family and friends and get away with pretending they made it themselves. "5 So it was that the couple realized that they had a surplus of misshapen or damaged vegetables grown on the farm which were unsuitable for selling in the shop. Clara, not wishing to see them get thrown away, decided to turn them into soup.6 The soup met with the immediate approval of customers to the shop and Clara now produce different varieties. She spent much of the summer traveling up and down to London by rail, doing presentations of the soups. As a result, they are now served in first-class railway restaurant cars belonging to three companies as well as being stocked by a number of high-class London stores.Paragraph 4____【单选题】

A.Time well spent is rewarded

B.Professional recognition is obtained

C.A necessary alternative to farming

D.Professional skills are exploited

E.Continuing investment in high standards

F.Ensuring that nothing gets wasted

正确答案:E

答案解析:克拉拉的经营之道是为顾客提供最优质的服务，所以题目应为E，继续高标准的投资。

4、 Happiness If your sense of well-being fluctuates with stock market, you might be comforted to know that money can\'t buy you happiness anyway. In one American study conducted in 1993, level of income was shown to have an inverse relation to happiness: The group whose income had declined was happier overall than the group whose income had increased. A soon-to-be published review of the hundreds of studies on this subject supports the 1993 findings. In developed countries, the correlation between income and happiness is close to zero and sometimes negative. With a correlation between level of income and happiness somewhere between 0.12 and 0.18, the United States is near the bottom of the list; that factors other than income are overwhelmingly more important in explaining happiness. Also, as our material wealth increases, the gap between income and satisfaction with life seems to be widening. Predictably, money has its most positive effect on the poor, but once a person has achieved a minimal standard of living level of income has almost nothing to do with happiness. Close relationship, rather than money, is the key to happiness. Indeed, the number of one\'s personal friends is a much better indicator of overall satisfaction with life than personal wealth. One stands a better chance of achieving a satisfying life by spending time with friends and family than by striving for higher income. Incidentally, in the US, as people become richer, the probability of divorce increases. Our need for companionship is partly biological. All primates respond with pleasure to demonstrations of affection and with pain to loss of companionship. Isolated monkeys will sacrifice food just for the glimpses of another monkey. By ignoring our biologically programmed need for each other, we risk physical and mental distress. A recent cross-national study of mental depression in the US found that in advanced countries, there is a rising tide of major depression. Teenage suicides have increased in recent decades in almost all advanced countries. Moreover, in the US since World War Ⅱ, there has been an actual decline in the proportion of people who report themselves to be "very unhappy. " You can easily test the claim that companionship exceeds wealth as a source of happiness. Ask yourself which has a greater influence on your satisfaction with life: your income or the affection of your intimate companions and the well-being of your children? Conversely, which would make you more depressed: a reduction in salary or a divorce and isolation from your friends? Capitalism succeeds in creating material riches, but it is less successful in building companionable societies and protecting family integrity. But developing countries still have much work to do in pursuing material wealth, where a rise in productivity still greatly increases happiness. For poorer countries, the time is not yet ripe for a shift in priorities from wealth accumulation to companionship. Can we afford to believe that the pursuit of material gain will lead to self-fulfillment? We should continue to enjoy our wealth in good company, or else we may find that it is not satisfying. According to the author, which of the following is most likely to share our biological need for companionship besides the monkey?【单选题】

A. A swallow.

B.A pig.

C.An ape.

D.A dog.

正确答案:C

答案解析:根据常识来看，因为猿猴（C与猴子最接近，所以推测C最可能是答案。结合段首句的内容来看，这个句子是用作具体的例子例证“我们对友谊的需要有部分原因是出于动物的天性。”判断该句前句中提到的灵长目（猴子也属于灵长目）也应该是用来例证的，因此判断灵长目都应该具有对友谊的生理需要，因此判断C（猿猴）是答案。
