點(diǎn)點(diǎn)英語繆金華：2009考研英語爭議題解析

　　本題問文章的第一二兩段顯示了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. 由這些粗體All he needs to do，More than 60,000，without prescriptions(無須處方)，over-the-counter(通過柜臺)，sell DNA tests directly to the public我們就很容易得出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

　　本題問文章最有可能的標(biāo)題是什么，文中對DNA testing outside the lab雖有涉及，但是but some observers are skeptical, critics also argue 這兩段是大頭，重點(diǎn)信息，說明了存在的問題，所以C不完整，此外系譜學(xué)家(genealogists)的研究也需要實(shí)驗(yàn)室的，文中只是交代了進(jìn)行DNA測試可能出現(xiàn)的問題，是在實(shí)驗(yàn)室內(nèi)外都有可能出現(xiàn)的問題。

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

　　B) takes efforts of generations

　　本題問第一段中對于新的教育體制的建立的描述。本題定位非常明確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.句子大意為，很幸運(yùn)前面的傳統(tǒng)觀點(diǎn)是錯誤的，因?yàn)�，建立新的教育體制并讓足夠的人通過(并讓足夠的人接受教育)，想靠這種方法改善經(jīng)濟(jì)水平需要2至3代人的努力。因此不難得出B) takes efforts of generations，而D) requires sufficient labor force，文中提到的them不是labor force，而是需要通過教育體制的人，并且要靠這些人通過教育體制來改善經(jīng)濟(jì)需要幾代人的努力，并沒有提到新的教育體制的建設(shè)需要充足的勞動力，兩者之間沒有關(guān)系。

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

　　C) when people no longer went hungry

　　本題問作者引用祖先的例子是為了說明教育是在什么情況下出現(xiàn)的，我們定位到原文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.文中的例子是為此段的主題服務(wù)的，那么此段的主題是什么呢?理解主題需要知道suspect的深層含義：懷疑其為真，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]中的后一個that指代，that就是指代continuing economic growth promotes the development of education even when governments don't force it. 因此我們選擇C) when people no longer went hungry在解決了溫飽的情況下才可以談教育。第三，雖然例子中談到了時間，但沒有時間是什么造成的呢?是需要花時間去找獵物來填飽肚子而沒了受教育的時間～,C答案流于表面化，只有是否餓肚子和經(jīng)濟(jì)發(fā)展邏輯上相關(guān)。
