Question

　　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, which are now being tried in several countries, and with several subjects, of which English is only one．

　　Specialists say that this sleep-study method speeds language learning tremendously． 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 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 over the radio at intervals (间歇) of a fortnight． Each lesson lasted twelve hours ---- from 8 p．m． to 8A．m． The first three hours of English grammar and vocabulary were given with the student awake． At 11 p．m． a soothing lullaby (使人镇静的催眠曲) 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 2A． m． a sharp noise was sent over the radio to wake the sleeping student up for a few minutes of revision． 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 breakfast．
