問題詳情：

Many students try to study the whole night and not sleep before an exam. Two separate studies show this may do more harm than good. The studies found a good night's sleep may improve memory. The findings of both studies appeared in the publication Nature.

Scientists at the University of Chicago did one of them. They trained students to listen to unclear speech produced by a machine.

Some students listened to the recording after ____________________. Others were tested twelve hours after the training, with no sleep. Guess what? The students who slept understood the recording better.

Professor Daniel says sleep has at least two effects on learning. One is to strengthen memories and protect them against interference(干擾). The second is to recover memories that have been lost.

The study suggested that memories are recorded in three steps. Scientists say the process is similar to the way a computer stores information, but in humans, they say, the second step requires sleep. So remember that!
