点点英语缪金华：2009考研英语争议题解析

　　本题问文章的第一二两段显示了PTK的什么。[b]All he needs to do[/b] is shell out $30 for a paternity testing kit at his local drugstore—and another $120 to get the results.

　　[b]More than 60,000[/b] people have purchased the paternity testing kits since they first became available [b]without prescriptions[/b] last year, according to Doug Fogg, chief operating officer of Identigene, which makes the [b]over-the-counter[/b] kits. [b]More than two dozen companies[/b] sell DNA tests [b]directly[/b] to the public, ranging in price from a few hundred dollars to more than $2,500. 由这些粗体All he needs to do，More than 60,000，without prescriptions(无须处方)，over-the-counter(通过柜台)，sell DNA tests directly to the public我们就很容易得出A) easy availability易得性(很容易得到)。

　　30. An appropriate title for the text is most likely to be ______.

　　B) DNA tests and its problems C) DNA testing outside the lab

　　本题问文章最有可能的标题是什么，文中对DNA testing outside the lab虽有涉及，但是but some observers are skeptical, critics also argue 这两段是大头，重点信息，说明了存在的问题，所以C不完整，此外系谱学家(genealogists)的研究也需要实验室的，文中只是交代了进行DNA测试可能出现的问题，是在实验室内外都有可能出现的问题。

　　32. It is stated in paragraph 1 that the construction of a new education system _____.

　　B) takes efforts of generations

　　本题问第一段中对于新的教育体制的建立的描述。本题定位非常明确We are fortunate that it is, because building new educational systems there and putting enough people through them to improve economic performance would require two or three generations.句子大意为，很幸运前面的传统观点是错误的，因为，建立新的教育体制并让足够的人通过(并让足够的人接受教育)，想靠这种方法改善经济水平需要2至3代人的努力。因此不难得出B) takes efforts of generations，而D) requires sufficient labor force，文中提到的them不是labor force，而是需要通过教育体制的人，并且要靠这些人通过教育体制来改善经济需要几代人的努力，并没有提到新的教育体制的建设需要充足的劳动力，两者之间没有关系。

　　34. The author quotes the example of our ancestors to show the education emerged ____.

　　C) when people no longer went hungry

　　本题问作者引用祖先的例子是为了说明教育是在什么情况下出现的，我们定位到原文What is the real relationship between education and economic development? I have begun to suspect that continuing economic growth promotes the development of education even when governments don't force it. After all, that's how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn't have time for education. They didn't have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.文中的例子是为此段的主题服务的，那么此段的主题是什么呢?理解主题需要知道suspect的深层含义：怀疑其为真，第二，要知道I have begun to suspect that continuing economic growth promotes the development of education even when governments don't force it. [b]After all, that's how education got started.[/b]中的后一个that指代，that就是指代continuing economic growth promotes the development of education even when governments don't force it. 因此我们选择C) when people no longer went hungry在解决了温饱的情况下才可以谈教育。第三，虽然例子中谈到了时间，但没有时间是什么造成的呢?是需要花时间去找猎物来填饱肚子而没了受教育的时间～,C答案流于表面化，只有是否饿肚子和经济发展逻辑上相关。
