Question

It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.

However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.

【解析】

試題分析：文章講述的是有關“夢”的研究。每個人都做夢，有的夢持續(xù)時間長，有的卻很短。有測試顯示，夢每隔90分鐘循環(huán)一次，一個循環(huán)經(jīng)歷六個階段。人們常說的做夢，發(fā)生在第六個階段。

1.It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds.”可知，有的夢持續(xù)很長時間，有的卻很短暫。故選B。

2.these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place.”可知，夢以90分鐘為一個循環(huán)，每個循環(huán)分為六個階段，做夢發(fā)生在第六個階段，故選D。

3.In the last stage people experience rapid eye movement, known as REM, ...Eighty percent of people who were woken during this sixth stage could easily remember their dreams.”可知，在第六階段即快速眼動階段醒來的話，很容易記得夢境，故選B。

4.who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half.”可知，劃線詞指的是夜里醒來以后很難再次入睡，這個狀態(tài)持續(xù)一個半小時，故選B。
