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 (实验) to test “the learn while you sleep” method (方法), which is now being tried in several countries, and with several subjects. English is among them.

Scientists say that this sleep study method greatly speeds language learning. They say that the ordinary 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. However, sleep teaching will only put into your head what you have studied already while you are awake.

In one experiment, ten lessons were broadcast over the radio for two weeks. Each lesson lasted twelve hours — from 8 p.m. to 8 a.m. The first three hours of English grammar and vocabulary (词汇) were given with the students awake. At 11 p.m. a lullaby (催眠曲) was broadcast to send the student to sleep and for the next three hours the radio in a soft and low voice broadcast 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 to go over the lesson. The soft music sent him back to rest again while the radio went on. At 5 o’clock his sleep ended and he had to go through the lesson again for three hours before breakfast.
