  2011新gre考试实施以来,参加了新版gre考试的考生都觉得阅读部分的题难度增加了,这主要是由于新gre考试逻辑阅读需要考生的逻辑反应一定要比以前更快,可能考生还是有点不习惯,或是没有准备充足。那么,接下来的几天,小编将给大家搜索整理一些新gre考试逻辑阅读的练习题,希望考生能从平日的练习中总结规律,找到解题技巧。

  Questions 1 to 3 are based on the following reading passage.

  One advantage of breeding African bees with other bee types (Africanization) may be resistance to the para-sitic mite Varroa jacobsoni, a major threat to modern beekeeping. In parts of Europe, this mite is devastating 5 honeybees and killing many colonies despite preventive measures by beekeepers. But in Brazil Varroa jacobsoni has been present in Africanized bees since 1972 without the loss of a single colony, even though beekeepers there undertook no preventive measures. The mites lay eggs 10 within the brood cells of immature bees, and developing mites feed on the hemolymph (blood) of bee pupae. But fewer mites reproduce in Africanized bees than in European bees. Some researchers point out that this resistance may be related to the Africanized worker bee's 15 shorter development period, which prevents some mites from reaching maturity. Recently the mite has become a serious problem in colonies of European bees in North America. Africanization of these bees may be the best safeguard against this parasite.

      For the following question, consider each of the choices separately and select all that apply

  1. The author cites all of the following as evidence that Africanized bees' resistance to Varroa jacobsoni is superior to that of European bees:

  □A Varroa jacobsoni is killing many bee colonies in Europe.

  □B Beekeepers in Brazil have not used preventive measures to protect their colonies.

  □C At least some European bee colonies have been saved by preventive measures.

  2. Select the sentence that indicates one possible reason the Africanized bees in Brazil have successfully resisted Varroa jacobsoni .

  3. The author's argument regarding the resistance of Africanized bees to Varroa jacobsoni would be most weakened if which of the following were true?

  ○A The bees in Brazil were resistant before being Africanized.

  ○B The number of bee colonies in North American increased dramatically whereas the number in Brazil remained unchanged.

  ○C Mites found in European bees reproduce at a faster rate than mites of identical species found in the bees in Brazil.

  ○D Africanized bees retain many of the characteris- tics of European bees.

  ○E Bee colonies in Europe continue to produce greater quantities of honey than do those in Brazil.

  正确答案: 1. AB 2. Some researchers point out that... 3. A

  以上即是阅读练习题,对于新gre考试逻辑阅读,考生除了采取题海战术,其实更应该做的就是总结。如果能从平日的练习中找到解新gre考试逻辑阅读题的思路,那么,要比采取题海战术更好。
