編輯推薦：2021年上半年公共英語(yǔ)三級(jí)閱讀理解練習(xí)題匯總

American society is not nap( 午 睡 ) friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvanian 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% of American adults nap when given the opportunity. We seem to have "a mid afternoon

quiet phase" also called "a secondary sleep gate." Sleeping 15 minutes to 2 hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap.

We Superstar 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, cars, planes and boats; on floors and beds; and in libraries, offices and museums.

Passage 2

Most people have had a dog or wanted one as their companion at some time in their lives. If you are thing of buying a dog, however, you should first decide what sort of companion you need and whether the dog is likely to be happy in the surroundings you can provide. Specialists' advice is useful to help you choose the most suitable kind of dog. But in part the decision depends on common sense. Different dogs were originally developed to perform specific tasks. So, if you want a dog to protect you or your

house, for example, you should choose the one that has the right size and characteristics. You must also be ready to devote a great deal of time to training the dog when it is young and give it the exercise it needs through out its life, unless you live in the countryside and can let it run freely. Dogs are demanding pets. Cats love the house and so are satisfactory with their place where it is secure, but a dog is loyal to its master and consequently wants him to show proof of his affection. The best time to buy a baby dog is when it is between 6 and 8 weeks old so that it can transfer its love from its mother to its master. If baby dogs have not established a relationship with the human being until they are over three months old, their strong relationship will always be with dogs. They are likely to be shy when they are brought out into the world to become good pets.
