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.
The dream experienced in the poem most likely occurred during ______.
选项 A、Stage 2 of NREM
B、Stage 3 of NREM
C、Stage 4 of NREM
D、the REM state
答案D
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、记得最清楚。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，选[D]。
