Mel: The official salary for judges has always been too low to attract the best Candidates to the job. The legislature’s move to raise the salary has done nothing to improve the situation, because it was coupled with a ban on receiving money for lectures and teaching engagements. Pat: No, the raise in salary really does improve the situation. Since very few judges teach or give lectures, the ban will have little or no negative effect. Pat’s response to Mel is inadequate in that it A. attempts to assess how a certain change will affect potential members of a group by providing evidence about its effect on the current members.(现在代表未来) B. mistakenly takes the cause of a certain change to be an effect of that change(因果倒置) C. attempts to argue that a certain change will have a positive effect merely (无a有b) by pointing to the absence of negative effects D. simply denies Mel’s claim without putting forward any evidence in support(无证据) of that denial E. assumes that changes that benefit the most able members of a group(部分代表全部) necessarily benefit all members of that group. 我认为这道题正确答案应该在 c和e之间,答案却是a,不明白呀 Q36 The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.
Which of the following, if true, provides the most support for the researchers’ hypothesis? A. Even after long periods of sleep when adenosine is at its lowest concen- tration in the brain, the number of brain cells bound with adenosine remains very large. B. Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to sites on brain cells. C. Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body. D. Some areas of the brain that are relatively inactive nonetheless release some adenosine. E. Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are high. 两个疑问1.cause the onset of sleep,这句话怎么理解,是说破坏了睡眠呢,还是说导致进入睡眠状态? 2.b为什么正确,e为什么错. 多谢指教!!
