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

　　These people have taken part in one of recent experiments to test“Learn-While-Sleep”ways. People are now trying these ways in several countries and with several subjects. English is one of them.

　　Specialists（专家）say that“sleep-study”way speeds language learning greatly. 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 effect his rest in any way. A word of warning: sleeping teaching will only strengthen（加强）in your mind what you have already studied while you are awake.

　　In an experiment, people gave lessons over the radio. Each lesson lasted twelve hours from 8 p. m to 8 a. m. People gave the students awake the first three hours of English grammar and vocabulary. At 11 p. m. people let the students listen to a lullaby（催眠曲）to sleep and for the next three hours the radio whispered the lesson again into the students' ears, At 2 a. m. people sent a sharp noise over the radio to wake the sleeping students up for a few minutes to review the lesson. The soft song sent the students back to rest again while the radio went on. At 5 a. m. their sleep was over and they had to go through the lesson again for three hours before breakfast.

　　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.
