单选题 {{B}}C{{/B}}
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 I saw something beautiful, I'm sure--
Then someone spoke,
And then I didn't see it any more,
Because I 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.
单选题 The poet compares her dream to kettle-steam because ______.
【正确答案】 C
【答案解析】推理判断题。该比喻处于诗的第三行:And all the dream went out like kettle-steam。由于like kettle-steam修饰的是谓语动词went out(消失),且后文论述的又是醒后不记得梦的内容,故选[C]。
单选题 Many people remember nothing about their dreams when they awake. The person in the I ______.
【正确答案】 A
【答案解析】细节题。诗的第十一行指出;I can't remember,说明她记不起梦的内容,而诗的一开始就说她做了一个梦,因此结合这两处即可知答案是[A]。
单选题 Which of the following statements is NOT true?
【正确答案】 A
【答案解析】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不符;[B]与诗的意思一致,[C]对应于第四段第三句;[D]对应于第四段第四句。
单选题 The dream experienced in the poem most likely occurred during ______.
【正确答案】 D
【答案解析】推理判断题。文章第三段指出,NREM状态下的第1、2阶段中我们不做梦,而第3、4两个阶段中做的梦通常我们都记不起来;在第四段则指出,在REM状态下我们做的梦最多。而诗中描述的梦境作者能记起来很有趣,只是记不起具体内容,因此应当属于REM状态下做的梦,故选[D]。
