这篇文章我也是问题多多，都做了2,3遍了还是错得一塌糊涂！关键是很多地方都找不到文中相应的地方。不过幸好，第五题我还做对了。文中这么说的：“Until recently it was assumed that ...This theory ignores the fact that ”又是假设又没有事实根据，所以自然是B了。D说的deductive reasoning应该是说“经过演绎推理得出的理由”，应该是正面的评价吧？
我想问其他几个问题：
第一题：
[center]The author is primarily concerned with
(A) showing that behavior is a more effective way of controlling bodily temperature than innate mechanisms
(B) criticizing researchers who will not discard their theories about the effects of microwave radiation on organisms
(C) demonstrating that effects of microwave radiation are different from those of other forms of radiation
(D) analyzing the mechanism by which an organism maintains its bodily temperature in a changing thermal environment
(E) discussing the importance of thermoreceptors in the control of the internal temperature of an organism[/center]
我想知道，文章的主题句是否是第一句？如果是，那么里面根本没有提到微波，这里怎么会选C而不是D？如果不是第一句，那么应该是哪句？我怎么看不出来？因为这个问题，导致第3，7题都做错了！
№4：
The author’s strategy in lines 39-42 is tofficeffice" /><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com[img][/img]
(A) introduce a hypothetical example to dramatize a point
(B) propose an experiment to test a scientific hypothesis
(C) cite a case study to illustrate a general contention
(D) produce a counterexample to disprove an opponent’s theory（A）
(E) speculate about the probable consequences of a scientific phenomenon
我不知道答案A所说的hypothetical example 是指的什么？这个文章里面哪有假设的例子了？
总的来说，这篇文章给我的感觉是内容不难，但是结构特别模糊，主题不鲜明，读起来很容易搞糊。但愿考试不要碰到这样的题目！God Bless Me！
