1题:One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in NorthAmerica enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on.At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world’s people; yet we consume one-third of the world’s resources.
As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter.But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources.
AsAmericans consuming such a disproportionate share of the world’s resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine’ the presumed link between our level of well-being and the level of material goods consumeD、If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanceD、But if you have a loaf of bread, then an additional crust of bread doesn’t make that much difference. In the eyes of most of the world today,Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we’re going to have to answer, whether we’re trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch.
The prospect of a scarcity of, and competition for, the world’s resources requires that we reexamine the way in which we relate to the rest of the worlD、It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.
According to the passage, it has long been believed that ______.

A、people in poor countries scarcely know how to enjoy a high standard of living
B、the world’s resources being limited, people in underdeveloped countries are bound to live a poor life
C、mostAmericans know that the world’s resources of many kinds are becoming scarce
D、it is impossible for all the people in the world to improve their living standards

I was addressing a small gathering in a suburban Virginia living room-a women’s group that had invited men to join them. Throughout the evening, one man had been particularly talkative, frequently offering ideas and anecdotes, while his wife sat silently beside him on the couch. Toward the end of the evening, I commented that women frequently complain that their husbands don’t talk to them. This man quickly nodded in agreement. He gestured toward his wife and said, "She’s the talker in our family. " The room burst into laughter; the man looked puzzled and hurt. "It’s true," he explaineD、" When I come home from work I have nothing to say. If she didn’t keep the conversation going, we’d spend the whole evening in silence. "
This episode crystallizes the irony that althoughAmerican men tend to taXk more than women in public situations, they often talk less at home.And this pattern is wreaking havoc with marriage.
The pattern was observed by political scientistAndrew Hacker in the late 1970s. SociologistCatherine Kohler Riessman reports in her new bookDivorce Talk that most of the women she interviewed-but only a few of the men-gave lack of communication as the reason for their divorces. Given the current divorce rate of nearly 50 percent, that amounts to millions of cases in the United States every year-a virtual epidemic of failed conversation.
In my own research, complaints from women about their husbands most often focused not on tangible inequities such as having given up the chance for a career to accompany a husband to his, or doing far more than their share of daily life-support work like cleaning, cooking and social arrangements. Instead, they focused on communication: "He doesn’t listen to me. " "He doesn’t talk to me. " I found, as Hacker observed years before, that most wives want their husbands to be, first and foremost, conversational partners, but few husbands share this expectation of their wives.
In short, the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk.

4题:It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. You might tolerate the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a "Be Kind to OtherDrivers" campaign, otherwise, it may get completely out of hanD、
Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behaviors. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring.A、friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance, which is so necessary in modern traffic conditions.But such acknowledgements of politeness are all too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.
However, improper politeness can also be dangerous.A、typical example is the driver who waves a child across a crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to.
A、veteran driver, whose manners are faultless, told me it would help if motorists learn to filter correctly into traffic streams one at a time without causing the total blockages (堵塞) that give rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone be well-mannered on the roaD、Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.
The most cool-headed and good-tempered of drivers are likely to take revenge when they are exposed to rude behaviors.

7题:完全依赖蜜蜂授粉的植物,用丰富的花蜜和花粉来吸引授粉者,而花蜜和花粉是蜜蜂的全部食物。随着某种授粉植物适应程度的提高,蜜蜂只为单一的某种植物授粉,并从那里获得营养。同样,有些种类的植物的花朵已经进化到了只能由某一种蜜蜂来授粉的地步。这类植物冒着灭绝的巨大危险,如果不经意地使用杀虫剂把授粉蜜蜂毁灭的话,这种植物也就不能再生存了。
以上资料如果为真,最强地支持了以下哪项结论
A.最早的开花植物种类与最早的蜜蜂种类同时在地球上出现
B.如果某种植物的惟一授粉者不存在灭绝的危险的话,那么这种被授粉的植物也不可能灭绝
C.大部分的开花植物种类的花朵吸引某些种类蜜蜂而不吸引另一些种类的蜜蜂
D.某些植物产地的彻底灭绝会导致某些蜜蜂种类的灭绝
E.人们从现在起就应该注意适当采取措施来实现植物授粉蜜蜂的多样性

8题:When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi
A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy.
Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin.
Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu.
What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago.
Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003.
What can be inferred in the passage concerningBoeing

A、Its headquarter has been moved fromChicago to Seattle.
B、It’s to be blamed for the economic depression in Washington.

C、Boeing itself is having a hard time.
D、It’s expected to have a revival in the year 2003.
