    Medical experts say most Americans do not get enough sleep. They say more Americans need to take a nap—that is to rest for a short period in the middle of the day. They give people advice to sleep lightly before continuing with other activities. The experts say naps might improve health by reducing pressure.

    Some European and Latin American companies have supported the idea of napping for many years. They ask people to leave work, go home and have a nap before returning. In the United States, some companies let workers rest simply in their offices. They believe this can help workers make fewer mistakes and also increase the amount of work that a person can do.

Sleep experts say it is likely that people make more mistakes at work than at other times. They say people should not carry out important tasks when they feel sleepy. And they say the best thing to do is to take a nap. About twenty minutes of rest is all you need. Experts say this provides extra energy and can increase your effects until the end of the day. But experts said that a nap should last no more than twenty to thirty minutes. A longer nap will put the body into sleep and waking up will be difficult.

阅读下面的短文，掌握大意，然后从四个选项中，选出一个最佳选项。

When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.

Large Internet companies such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems (系统). These systems send the heat into the air.

A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy So the company developed a special device(仪器，装置)—the e-Radiator.

Boaz Leupe, head of the company, says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.

Five home owners in Holland are testing the heating system in their homes.

"We pay for the computer using, so, in that way, home owners get heating for free,"Boaz says.

Jan Visser is one of the home owners. "If you use the computer more, the e-Radiator producers more heat, "he says, "It cannot provide enough heat if you don't use your computer often." But he is ready to try it. It's a great help for his family.

The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.
