Real policemen, both Britain and the United States, hardly recognize any resemblance between their lives and what they see on TV - if they ever get home in time. There are similarities, of course, but the cops don't think much of them. The first difference is that a policeman's real life revolves round the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to scantily clad ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilty-or not-of stupid, petty crimes. Most television crime drama is about finding the criminal; as soon as he's arrested, the story is over. In real life, finding criminals is seldom much of a problem: Except in very serious cases like murders and terrorist attacks-where failure to produce results reflects on the standing of the police-little effort is spent on searching. The police have an elaborate machinery which eventually shows up most wanted men. Having made an arrest, a detective really starts to work. He has to prove his case in court and to do that he often has to gather a lot of different evidence. Much of this has to be given by people who don't want to get involved in a court case. So as well as being overworked, a detective has to be out at all hours of the day and night interviewing his witnesses and persuading them, usually against their own best interests, to help him. A third big difference between the drama detective and the real one is the unpleasant moral twilight in which the real one lives. Detectives are subject to two opposing pressures: first as members of a police force they always have to behave with absolute legality, secondly, as expensive public servants they have to get results They can hardly ever do both. Most of the time some of them have to break the rules in small ways. If the detective has to deceive the world, the world often deceives him. Hardly anyone he meets tells him the truth. And this separation the detective feels between himself and the rest of the world is deepened by the simple mindedness-as he sees it-of citizens, social workers, doctors, law makers, and judges, who, instead of stamping out crime punish the criminals less severely in the hope that this will make them reform. The result, detectives feel, is that nine tenths of their work is recatching people who should have stayed behind bars. This makes them rather cynical.

{{B}}Passage 3{{/B}} American society is not nap (午睡) friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine. "There's even a prohibition against admitting we need sleep". Nobody wants to be caught napping or found asleep at work. To quote a proverb: "Some sleep five hours, nature requires seven, laziness nine and wickedness eleven." Wrong. The way not to fall asleep at work is to take naps when you need them. "We have to totally change our attitude toward napping", says Dr. William Dement of Stanford University, the godfather of sleep research. Last year a national commission led by Dement identified an "American sleep debt" which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Clinton is trying to take a half hour snooze (打瞌睡) every afternoon. About 60 percent of American adults nap when given the opportunity. We seem to have "a midafternoon quiet phase" also called "a secondary sleep gate." Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. We Superstars of Snooze don't nap to replace lost shut eye or to prepare for a night shift, Rather, we "snack" on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, ears, planes and on boats; on floors and beds; and in libraries, offices and museums.
