14. (26835-!-item-!-188;#058&002982)
The higher the level of certain vitamins and minerals in the bloodstream, the better a person's lung function, as measured by the amount of air the person can expel in one second. The lung function of smokers is significantly worse, on average, than that of nonsmokers. Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of foods that are rich in these helpful vitamins and minerals.
Which of the following is an assumption on which this argument depends?
(A) Smokers are less likely than nonsmokers to have diets that are rich in vitamins and minerals. (E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.
答案是E,我后来想想E也能想明白,但是A呢?
我的理解是smoker吃的维他命少(前提),所以肺更加不好(原文的中间结论),所以应该多吃点(原文结论)
有的时候做的急了,看到A直接选上去了,都看不到E选项了。。。。 这个习惯是不是很不好? |
