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.
