单选题Aspirin is one of the safest and most effective drugs invented by man. The most popular medicine in the world today, it is an effective pain reliever. Its bad effects are relatively mild. It is also cheap. For millions of people suffering from arthritis, it is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although relatively mild, are largely unrecognized among users. Although aspirin was first sold by a German company in 1899, it has been around much longer than that. Hippocrates, in ancient Greece, understood the medical value of tree barks and leaves which today are known to contain a chemical found in aspirin. During the 19th century. there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States. A small quantity of aspirin relieves pain and inflammation. It also reduces fever by affecting some of the body's reactions. Aspirin is very irritating to the stomach lining. The best way is to chew the tablets before swallowing them with water, but few people can stand the bitter taste. Some people suggest crashing the tablets in milk or orange juice.

单选题 Questions 6-10 are based on the following passage. The term control is highly—and unjustifiably—unpopular. Some of its unpopularity can be traced to educational and philosophical writings that have addressed issues of freedom, self- determination, self-worth, individuality, and other humanistic concerns—concerns often equated with liberal and permissive child-rearing and educational methods. They are the concerns that define the spirit of these times. No teacher wants to be nonliberal and restrictive. And there is little doubt that the deliberate exercise of control is restrictive. Is control therefore unethical? There is, of course, no simple answer, ff there were, there would be little controversy, and behaviorists and humanists would have much less to disagree about. Consider, first, that control is not only inevitable but also necessary. There is no doubt that teachers, by virtue of their position and by virtue of their duties, have control. Indeed, it is not at all unreasonable to insist that the exercise of control is one of the teacher's most important duties. We are not speaking here of a fear-enforced control that might have been characteristic of some of yesterday's schools. Control can be achieved, or at least facilitated, in a variety of gentle ways, some of which can be learned． Parents too control their children (or at least try), often by setting limits for their behavior. Part of the successful socialization process requires that children be prevented from engaging in behaviors that might be injurious to themselves or to others. Thus, parents do not permit their children to play with the dinner as it is cooking on the stove, to insert knives into electrical outlets, to jump off ladders, or to swim in dangerous waters. Less extreme instances of control involve the teaching of socially appropriate behavior, of values and morals—of "shoulds" and "should nots". It is less by accident than by virtue of parental control that children learn not to deface wall, steal other people's property, or kill the neighbor's god． In short, certain standards of behavior are learned at least partly as a function of parental control. Whether that control involves reinforcement, punishment, models, reasoning, or a combination of these and other strategies, we cannot avoid the fact that control is being exercised． The classroom situation is not really very different. Teachers have often been described as acting [in loco parentis]—in the place of parents. More precisely, teachers have been urged to act in all ways as might a wise, judicious, and loving parent. And there is, in fact, no great incompatibility between values held in highest esteem by those who describe themselves as humanistically oriented and the techniques of behavior control that have been described by science. Love, empathy, warmth, genuineness, and honesty can go a long way toward ensuring a classroom climate corducive to and learning and development. In spite of these highly desirable qualities, however, discipline problems are not uncommon in classrooms. That teachers should judiciously administer rewards and punishment in an effort to maintain an effective educational environment does not mean that they care less for their students; indeed, in might well indicate that they care more.

单选题What"s your earliest childhood memory? Can you remember learning to walk or talk? The first time you 1 thunder or watched a television program? Adults seldom 2 events much earlier than the year or so before entering school, just as children younger than three or four 3 retain any specific, personal experiences. A variety of explanations have been 4 by psychologists for this "childhood amnesia" (儿童失忆症). One argues that the hippocampus, the region of the brain which is responsible for forming memories, does not mature 5 about the age of two. But the most popular theory 6 that, since adults do not think like children, they cannot 7 childhood memories. Adults think in words, and their life memories are like stories or 8 —one event follows 9 as in a novel or film. But when they search through their mental 10 for early childhood memories to add to this verbal life story, they don"t find any that fits the 11 . It"s like trying to find a Chinese word in an English dictionary. Now psychologist Annette Simms of the New York State University offers a new 12 for childhood amnesia. She argues that there simply 13 any early childhood memories to recall. According to Dr. Simms, children need to learn to use 14 spoken description of their personal experiences in order to turn their own short-term, quickly 15 impressions of them into long-term memories. In other 16 . children have to talk about their experiences and hear others talk about 17 —Mother talking about the afternoon 18 looking for seashells at the beach or Dad asking them about their day at Ocean park. Without this 19 reinforcement, says Dr. Simms, children cannot form 20 memories of their personal experiences.
