According to a review of 61 studiesof patients suffering from severely debilitating depression, a large majorityof the patients reported that missing a night's sleep immediately lifted theirdepression. Yet sleep-deprivation is notused to treat depression even though the conventional treatments, which usedrugs 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 fordepression? (A) For a small percentage ofdepressed patients, missing a night's sleep induces a temporary sense ofeuphoria. (B) Keeping depressed patientsawake is more difficult than keeping awake people who are not depressed. (C) Prolonged loss of sleep canlead to temporary impairment of judgment comparable to that induced byconsuming several ounces of alcohol. (D) The dramatic shifts in moodconnected with sleep and wakefulness have not been traced to particular changesin brain chemistry. (E) Depression returns in fullforce as soon as the patient sleeps for even a few minutes.
答案是E,我选的C,因为我觉得C是在说不睡眠会产生和酒精一样的让人缺乏正确判断力的作用,也就是说病人以为自己不忧虑了,其实还是忧虑的,所以不睡觉产生的改善是虚假的。 E我也明白,是对的。但是为什么C错了?或者为什么C不如E?
