10. A company's two divisions performed with remarkable consistency over the past three

years: in each of those years, the pharmaceuticals division has accounted for roughly 20

percent of dollar sales and 40 percent of profits, and the chemicals division for the

balance.  
Which of the following can properly be inferred regarding the past three years from the

statement above?  
(A) Total dollar sales for each of the company's divisions have remained roughly

constant.  
(B) The pharmaceuticals division has faced stiffer competition in its markets than has the

chemicals division.  
(C) The chemicals division has realized lower profits per dollar of sales than has the

pharmaceuticals division.  
(D) The product mix offered by each of the company's divisions has remained

unchanged.  
(E) Highly profitable products accounted for a higher percentage of the chemicals

division's sales than of those of the pharmaceuticals division.

Answer: C

这道题目虽然做对的，但是不知思路对不对。
我的思路是，这个公司就是由两个部门组成的，那么题目中的[the chemicals division for

the balance]就是说相对于医药部门，化工部门accounted for roughly 80 percent of dollar

sales and 60 percent of profits，60/80<40/20，这样推出C中的lower profits per dollar of

sales

11.  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.

题目没怎么看懂，也不知道为什么选E，请NN翻译翻译，指教指教。

10的思路如你所说应该没问题吧

11真是不知所云，开始说一大部分有抑郁症的人，说缺乏睡眠导致

然后转折说，“sleep-deprivation”

这里干吗要转折呢？

11题中的lift是什么意思？从题意上判断，应该和alleviate类似吧。

这样才会有人把sleep-deprivation作为治疗depression的方法。

而E说只要患者一睡觉，几分钟内depression就会复发。解释了原文。

还是不懂。

jerold0023说得有理。

lift是消除的意思。

这样一来，题干说61%的抑郁者觉得晚上不睡觉能减轻他们的症状。然后说尽管传统的治疗方法有副作用，但是不让睡觉并没有用来治疗。要你来解释一下为什么这样。

懂了。谢谢大家的帮助。

我还是不太明白，题目要解释为什么不让睡觉并不能治疗depression，而E选项说depression在病人睡了一会之后会马上恢复，虽然道出了睡眠与depression的关系，但是意思上简单点就是睡眠导致depression，这不就从侧面上证明了不让睡觉可以治疗depression吗？稀里糊涂啊~~请各位NN指点~~！！
