第1题：Before a big exam, a sound night’s sleep will do you more good than poring over textbooks. That, at least, is the folk wisdom.And science, in the form of behavioral psychology, supports that wisdom.But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. One says that sleep is when permanent memories form. The other says that they are actually formed during the day, but then "edited" at night, to flush away what is superfluous. To tell the difference, it is necessary to look into the brain of a sleeping person, and that is harD、But after a decade of painstaking work, a team led by Pierre Maquet at Liege University inBelgium has managed to do it. The particular stage of sleep in which theBelgian group is interested in is rapid eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as if watching a movie, and brainwave traces resemble those of wakefulness. It is during this period of sleep that people are most likely to relive events of the previous day in dreams. Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task during the day, and as they slept during the following night. The task required them to press a button as fast as possible, in response to a light coming on in one of six positions.As they learnt how to do this, their response times got faster. What they did not know was that the appearance of the lights sometimes followed a pattern — what is referred to as "artificial grammar". Yet the reductions in response time showed that they learnt faster when the pattern was present than when there was not. What is more, those with more to learn (i.e., the "grammar", as well as the mechanical task of pushing the button) have more active brains. The "editing" theory would not predict that, since the number of irrelevant stimuli would be the same in each case.And to eliminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they went to sleep. The team, therefore, concluded that the nerve connections involved in memory are reinforced through reactivation during REM sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soundly in the knowledge that what they will remember the next day are the basic rules of algebra and not the incoherent talk from the radio next door. The author mentions "maths students" as an example to show______. A、its significance in the study B、an inherent pattern being learnt C、its resemblance to the lights D、the importance of night’s sleep

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
