118. According to a review of 61 studies of patients suffering from severely debilitatingdepression, a large majority of the patients reported that missing a night’s sleep immediately lifted their depression. Yet sleep-deprivation is not used to treat depression even though the conventional treatments, which use drugs and electric shocks, often have serious side effects.
Which of the following, if true, best explains the fact that sleep-deprivation is not used as a
treatment for depression?
(A) For a small percentage of depressed patients, missing a night’s sleep induces a temporary
sense of euphoria.
(B) Keeping depressed patients awake is more difficult than keeping awake people who are
not depressed.
(C) Prolonged loss of sleep can lead to temporary impairment of judgment comparable to that
induced by consuming several ounces of alcohol.
(D) The dramatic shifts in mood connected with sleep and wakefulness have not been traced
to particular changes in brain chemistry.
(E) Depression returns in full force as soon as the patient sleeps for even a few minutes.
答案为E。但是我有点不理解。
这类问题应该如何分析？谢谢。
按照61份对罹患严重身体机能降低的病人的调查报告，大多数病人在经历了一夜的失眠后，身体机能降低的病患马上有所改善。但是睡眠缺乏仍旧没有用于治疗身体机能降低，尽管传统的方法------使用药物和电震经常有严重的副作用。
题目问的是，下面哪个选项可以为我们做出最好的解释------为什么睡眠缺乏没有用于治疗身体机能降低？
只有E给我们解释了：如果我们使用失眠来治疗，治疗后一旦病人即使睡了几分钟，病患又回到了原来的状态。而其他的几个选项和本题是无关的。
不知道MM哪里不是很理解，如果发贴的时候能说的比较详细具体什么地方不大理解，在做解答的时候就比较有针对性了。如果还是有问题，请继续跟贴。
