单选题Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem--how to collect body heat. They have designed a collection system which utilizes not only body heat, but also the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no conventional fuel is needed to make the campus's six buildings comfortable, Some parts of most modern buildings--theaters and offices as well as classrooms--are more than amply heated by people and lights and sometimes must be air-conditioned even in winter. The technique of saving heat and redistributing it is called"heat recovery."A few modern buildings recover heat, but the University's system is the first to recover heat from some buildings and re-use it in others. Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student studies, the more heat his body gives off. (80) Male students emit more heat than female students do, and the larger a student is, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hardworking, overweight male genius.

单选题Concerning money or anything else, conflicts between husband and wife usually reflect a power struggle. Conflicts between parent and child often center around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please, and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent training courses. Parents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behavior will be whatever the parents consider proper and constructive. But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is right. Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents" expectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents" values and ideas. Many parents feel that they get along with their adolescents quite well.

单选题Did you know that all human beings have a "comfort zone" regulating the distance they stand from someone when they talk? This distance varies in interesting ways among people of different cultures. Greeks, some of the Eastern Mediterraneen, and many of those from South America normally stand quite close together when they talk, often moving their faces even closer as they warm up in a conversation. North Americans find this awkward and often back away a few inches. Studies have found that they tend to feel most comfortable at about 21 inches apart. In much of Asia and Mrica, there's even more space between two speakers in conversation. This greater space subtly lends an air of dignity and respect. This matter of space is nearly always unconscious, but it is interesting to observe. This difference applies also to the closeness with which people sit together, the extent to which they lean over one another in conversation, how they move as they argue or make an emphatic (强调的) point. In the United States, for example, people try to keep their bodies apart even in a crowded elevator, in Paris they take it as it comes! Although North Americans have a relatively wide" comfort zone" for talking, they communicate a great deal with their hands--not only with gesture but also with touch. They put a sympathetic hand on a person' s shoulder to demonstrate warmth of feeling, or an arm around him in sympathy; they pat an arm in reassurance(放心)or stroke a child's head in fondness; they readily take someone's arm to help him across a street or direct him along an unfamiliar mute. To many people - especially those from Asia or the Moslem(穆斯林) countries--such bodily contact is unwelcome, especially if done with the left hand. The left hand carries no special significance in the U. S. Many Americans are simple left and use that hand more.
