今儿做GWD遇到一个好像和楼主描述的很像啊
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.
结论A结合的cells的累积数量导致了sleep的onset（有力的开始），问加强。
B说咖啡因能让人awake，是因为它interfere（干扰）A与cells的结合。
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 concentration 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.

我跟楼主的IR和阅读是同一个题库，基本上都是一样的！！！
