第3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

第4题：In 1924American’s National ResearchCouncil sent to engineers to supervise a series of industrial experiments at a large telephone-parts factory called the Hawthorne Plant nearChicago. It hoped they would learn how stop-floor lighting (1) workers productivity. Instead, the studies ended (2) giving their name to the "Hawthorne effect", the extremely influential idea that the very (3) to being experimented upon changed subjects’ behavior.
The idea arose because of the (4) behavior of the women in the Hawthorne plant.According to (5) of the experiments, their hourly output rose when lighting was increased, but also when it was dimmeD、It did not (6) what was done in the experiment; (7) something was changed, productivity rose.
A、(n) (8) that they were being experimented upon seemed to be (9) to alter workers’ behavior (10) itself.
After several decades, the same data were (11) to econometric the analysis. Hawthorne experiments has another surprise store (12) the descriptions on record, no systematic (13) was found that levels of productivity were related to changes in lighting.
It turns out that peculiar way of conducting the experiments may be have let to (14) interpretation of what happeneD、 (15) , lighting was always changed on a Sunday. When work started again on Monday, output (16) rose compared with the previous Saturday and (17) to rise for the next couple of days. (18) , a comparison with data for weeks when there was no experimentation showed that output always went up on Monday, workers (19) to be diligent for the first few days of the working week in any case, before (20) a plateau and then slackening off.

第5题：The invention of both labor-saving tools and tools of intelligence is rarely accidental. Instead, it is usually the product of human need; (21) is truly the mother of invention. People usually devise tools to (22) for natural deficiencies. For example, people invented weapons to defend (23) from physically superior (24) .But (25) is only one incentive for inventions. People also invent (26) tools to (27) certain established tasks more efficiently. For instance, people developed the bow and arrow from the (28) spear or javelin in order to shoot (29) and strike with greater strength.

One impetus for invention has always been the (35) for speed and high-quality results--provided they are achieved (36) reasonable costs.

Excitement, fatigue, and anxiety can all be detected from someone’s blinks, according to psychologist John Stern {{U}} (21) {{/U}} Washington University in St. Louis. Stern specialized in the study on these tiny twitches, using them as sensitive {{U}} (22) {{/U}} of how the brain works. "I use blinks as a psychological measure to make{{U}} (23) {{/U}} about thinking because I have very little {{U}} (24) {{/U}} in what you tell me about what you are thinking." He says. "If I ask you the question, ’what does the phrase a rolling stone gathers no moss mean ’ you can’t tell me {{U}} (25) {{/U}} you’ve started looking for the answer.But I can, by watching your eyes."
Blinks also tell Stern when you have understood his question--often long before he’s finished asking it--and when you’ve found an answer or part of {{U}} (26) {{/U}}. "We blink at times {{U}} (27) {{/U}} are psychologically important." He says. "You have listened to a question, you understand it, {{U}} (28) {{/U}} you can take time out for a blink.Blinks are {{U}} (29) {{/U}} marks. Their timing is tied to what is going on in your {{U}} (30) {{/U}}."
Stern has found that {{U}} (31) {{/U}} suppress blinks when they are absorbing or anticipating {{U}} (32) {{/U}} but not when they’re reciting it. People blink later, for example, {{U}} (33) {{/U}} they have to memorize six numbers instead of two. "You don’t blink," he says, "until you have {{U}} (34) {{/U}} the information to some short-term memory store."And if subjects are cued {{U}} (35) {{/U}} the set of numbers is coming, say, five seconds, they’ll curb their blinks until the task is {{U}} (36) {{/U}}. Similarly, the more important the information that people are taking in, the more likely they are to put their blinks on hold for {{U}} (37) {{/U}} Pilots blink less when they’re {{U}} (38) {{/U}} for flying a plane than when they {{U}} (39) {{/U}} their eyes from the road to the rearview mirror.But if they see the flashing lights of a state trooper behind them, their {{U}} (40) {{/U}} will move fast to the speed-meter and back to the mirror.

第7题：山奇是一种有降血脂特效的野花，它数量特别稀少，正濒临灭绝。但是，山奇可以通过和雏菊的花粉自然杂交产生山奇一雏菊杂交种子。因此，在山奇尚存的地域内应当大量地人工培育雏菊，虽然这种杂交品种会失去父本或母本的一些重要特性，例如不再具有降血脂的特效，但这是避免山奇灭绝的几乎唯一方式。
上述论证依赖于以下哪项假设
Ⅰ只有人工培育的雏菊才能和山奇自然杂交。
Ⅱ在山奇生存的地域内没有野生雏菊。
Ⅲ山奇一雏菊杂交种子具有繁衍后代的能力。A．只有Ⅰ
B．只有Ⅱ
C．只有Ⅲ
D．只有Ⅱ和Ⅲ
E．Ⅰ、Ⅱ和Ⅲ
