问题     Oh! I have just had such a lovely dream! and then I woke, and all the dream went out like kettle-steam or chimney-smoke. My dream was all about — how funny, though! I’ve only just dreamed it, and now it has begun to blow away like dust.
   In it I went  no! In my dream I had — No, that’s not it! I can’t remember, oh, it is too bad, My dream a bit. But l saw something beautiful, I’m sure — Then someone spoke, and then l didn’t see it any more, Because l woke.
   What do we do every night, whether we know it or not? We dream. Researchers have found that we dream about the same amount on nights that we remember our dreams as on the nights that we don’t. The amount of time we sleep is broken into cycles and states. There are two states of sleep:
   The first state, is called NREM, or non-rapid eye movement. It consists of four stages: Stage 1 is when we feel relaxed and sleepy. Stage 2 is when we move into a light sleep. We don’t dream in these two stages. Stages 3 and 4 are called slow-wave sleep. In these stages, we are in a deep sleep and the dreams we have are ones we don’t usually remember.
   The second state is called REM, or rapid eye movement. This is when we dream the most and have the dreams we remember the most. For many people, their REM dreams are the most meaningful and visually exciting. Approximately three-fourths of our total sleep time is spent in the NREM state and one-fourth in the REM state. We sleep by cycling through these states. Throughout the night, we experience four to six NREM/REM cycles.
Which of the following statements is NOT true?
选项 A、Dreams experienced during Stages 3 and 4 are the most memorable.
B、Most of our sleep time is spent in the non-rapid eye movement state.
C、REM dreams tend to be more exciting than NREM dreams.
D、We spend more time in NREM sleep than in REM sleep.
答案A
解析 细节题。本题为细节比对题。文章第三段指出的四个阶段都属于NREM状态，而第四段说明的则是REM状态，[A]因此与该段第二句话以及上一段最后一句不符；[B]与第四段第四句的意思一致；[C]对应于第四段第三句；[D]对应于第四段第四句。
