To Learn English While You Sleep

　　If you ask some people, “How did you learn English so well?”you may get a surprising answer:“In my sleep!”

　　These are people who have taken part in one of the recent experiments to test learn-while-you-sleep methods (方法), which are now being tried in several countries, and with several subjects, of which English is only one.

　　Specialists(专家) say that this sleep-study method speeds language learning tremendously(巨大地). They say that the average person can learn two or three times as much during sleep as in the same period during the day－and this does not affect(影响) his rest in any way. A word of warning, however: sleep-teaching will only hammer into your head what you have studied already while you are awake.

　　In one experiment, ten lessons were broadcast(广播) over the radio at intervals of a fortnight ( two weeks). Each lesson lasted twelve hours－from: 8 p. m. to 8 a. m. The first three hours of English grammar and vocabulary were given with the student awake. At 11 p. m. a soothing (起镇静作用的) lullaby (催眠曲) was broadcast to send the student to sleep and for the next three hours the radio whispered the lesson again into his sleeping ears. At 2 a. m. a sharp noise was sent over the radio to wake the sleeping student up for a few minutes of revision (repeating a lesson ). Then he was lulled back to rest again while the radio purred on. At 5 o'clock his sleep ended and he had to go through the lesson again for three hours before his hard-earned breakfast.

“At three or four in the morning and I surf the net.”
“I often check my e-mail forty times a day.”
“I often spend more than three hours during one time on the net.”
“I spend more time in chat rooms than with my ‘real-1ife’ friends.”
Do you know any people like these? They are part of a new addiction（瘾）called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.
Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family.
