　　Living Space

　　How much living space does a person need? What happens when his space needs are not met? Scientists are doing experiments on rats to try to determine the effects of overcrowded conditions on man. Recent studies have shown that the behavior of rats is greatly affected by space. If rats have enough living space, they eat well, sleep well and produce their young well. But if their living conditions become too crowded, their behavior and even their health change obviously. They can not sleep and eat well, and signs of fear and worry become clear. The more crowded they are, and more they tend to bite each other and even kill each other. Thus, for rats, populations and violence are directly related. Is this a natural law for human society as well? Is enough space not only satisfactory, but necessary for human survival? These are interesting questions.

　　British and American Police Officers

　　Real policemen, both in Britain and the U.S., hardly recognize any common points between their lives and what they se on TV—if they ever get home in time.

　　Some things are almost the same, of course, but the policemen do not think much of them much of them.

　　The first difference is that a policeman’s real life deals with the law. Most of what he learns is the law. He has to know actually what actions are against the law and what facts can be used to prove them in court. He has to know nearly as much law as a lawyer, and what’s more, he has to put it into practice on his feet, in the dark and, running down a narrow street after someone he wants to talk to.

　　Little of his time is spent in talking with beautiful girls or in bravely facing cruel criminals. He will spend most of his working life arranging millions of words on thousands of forms about hundreds of sad, ordinary people who are guilty--- or not of stupid, unimportant crimes.

　　Useful Words and Expressions:

　　1. think much of 重視，尊重

　　2. in court 在法庭上

　　3. criminal 罪犯，犯罪者

　　4. guilty 犯罪的，有罪的
