(1)一日，王教授应邀到甲机关举办一场关于职业道德与行为规范关系的专题讲座。会场里

As the Internet becomes more popular, many older media (媒体) businesses are dying out. But TV seems to be doing OK. In fact, it's doing better than OK. Though the Internet is popular in the world, television continues to draw more and more people all over the world to many of its programs. Hundreds of millions turn to TV to watch World Cup soccer，Olympic Games and Discoveries.

In many places, increasing numbers of people can watch more TV than before. Ten years ago, only 44% of British homes had satellite or cable TV(卫星或有线电视).Today, more than 93% do. More importantly, recent studies show that people are spending more time watching TV. Surprisingly, this is even true of young people between the ages of 8 and 18.Today's television industry has given so many choices. As a result, people can watch more of the things they like 24 hours a day.

The technology behind television has also improved. The big boxes that once filled living rooms are gone. Today's TV screens are thinner and thinner, yet the pictures are better and better. TVs are also moving from living rooms into kitchens and vehicles.

For years, TVs have also been used as video game players. But now they have been used in a few new ways. Many televisions can connect to the Internet and record programs. They also let people watch two programs at the same time. Today the most modern television has been on the way of development.

The Internet is the main challenge (挑战) for television now. But TV industry has shown that television will be important for years to come.

American society is not nap (午睡)friendly . In fact , says David Dings , sleep specialist at the University of Pennsylvania School of Medicine , “There’s even a prohibition (禁止) 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(淘气的) eleven.”

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(发现) 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 (瞌睡) every afternoon .

About 60 percent 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 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 , cars , planes and on boats ; on floors and beds ;and in libraries ,  offices and museums .
