  5、[阅读理解]Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from the somatosensory neocortex(an area that processes sensory information)and the hippocampus, which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined. So-called sleep spindles(bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory consolidation. A second study, also published online this week by the Proceedings of the National Academy of Sciences, links age-associated memory decline to high glucose levels.

  What is the result of the experiment with rats and mice carried out at Rutgers University

  A、The electrical activity is emanating from the somatosensory neocortex.

  B、Oscillations in brain waves are from hippocampus.

  C、Somatosensory neocortex and hippocampus work together in memory consolidation.

  D、Somatosensory neocortex plays it primary role in memory consolidation.

  正确答案:C

  答案解析:答案选C。本段告诉我们,科学家分析了老鼠的脑电波,尤其是从somatosensory neocortex和hippocampus两个区域发出的脑电波。该段是后两句指出,这两个大脑区域的活动是互相作用的。本段并没有说 somatosensory neocortex或 hippocampus起主导作用。

  6、[概括大意]They always complained(抱怨) more or less justly, that their parents are out of touch with modern ways. They also blamed that their parents always have a final say. And the young felt that their parents do not trust their children to deal with crises. Besides, they dissatisfied too much murmurs of their parents about certain problems and the lack of sense of humor in dealing with the problems, at least in parents-children relationships.

  The main idea of this paragraph is__________.

  A、The criticisms to their parents can be kept out of the young people‘s mind in following ways.

  B、It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstanding between them.

  C、There are so many criticism to their parents among the young people.

  D、Young people have gotten enough reasons to criticize their parents.

  正确答案:C

  7、[阅读理解]The other side of a state legal apparatus is a state military apparatus. While the one protects the individual from violence, the other sacrifices the individual to violence in the interests of the state. In war the state affirms supreme power over the individuals within its own borders. War is not simply a trial by combat to settle disputes between states; it is the moment when the state makes its most powerful demands upon its people for their commitment, allegiance, and supreme sacrifice.

  The word “allegiance” is closest in meaning to ______.

  A、loyalty

  B、objective

  C、survival

  D、motive

  正确答案:A

  答案解析:解本题可用同类词关系进行判断。在“allegiance”前后的两个词分别是commitment和 sacrifice,应能判断出这三个词相对于国家而言是同一类词,再利用排除法,不难选出正确答案A。
