70. According to a review of 61 studies of patients suffering from severely debilitating depression, 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.

ANSWER: E

文章是说一天晚上睡不着，会使depression减少；但不推荐用睡眠剥夺的办法使depression减少，因为睡了一会后depression会增加？

题目说失眠了，就不压抑了（a large majority of the patients reported that missing a night's sleep immediately lifted their depression）。只有E解释了为什么不用剥夺睡眠的疗法，因为只要睡了几分钟，压抑重新又来了。

其他都无关

睡几分钟，抑郁又回来了：这个选项是怎么解释剥夺睡眠不被采用的说法呢？

lifted their depression 中的Lift是指改善的意思么？
