GRE阅读中有(yǒu)些选项和正确答(dá)案意思非常接近，我们可(kě)能(néng)会不太确定到底在两个相似的答(dá)案之间到底应该选什么，这个时候一定要遵守两个重要的原则。

第1：正确答(dá)案一定出自原文(wén)，原文(wén)一定会对正确答(dá)案提供或明确或隐晦的提示；

第二：两个较為(wèi)相似的答(dá)案如果难以抉择，要仔细观察到底这两个看似都挺正确的答(dá)案之间细微的差别是什么，即每个答(dá)案的侧重点是什么，或者这两者zui大的逻辑上的差异是什么。比如下题：

The waters east of Cape Hangklip were once the center of a lucrative wild-caught abalone fishery, but illegal fishing in the mid-1990s escalated to such levels that the recreational fishery was closed in 2003. When abalones did not rebound, commercial fishing was also banned. Continual declines in abalone were attributed to poaching, but an invasion by rock lobsters during the early 1990s probably intensified the trend. Rock lobsters prey on sea urchins, and increased rock lobster densities coincided with significant decreases in urchins. In that area, urchins feed largely by trapping drift kelp, and in doing so provide juvenile abalone with both protective shelter and nourishment. Without urchins’ presence, juvenile abalones are less likely to survive to adulthood.

According to the passage, which of the following is a true statement about the feeding behaviors of sea urchins

A. They change according to the type of food available in an area.

B. They are responsible for the decline of abalones in some regions.

C. They have a significant impact on the young of another species.

D. They make sea urchins more vulnerable to potential predators.

E. They result in marked decline in certain regions.

有(yǒu)些同學(xué)或许会觉得其实答(dá)案E也挺好的，确实如果按照原文(wén)的信息“In that area, urchins feed largely by trapping drift kelp, and in doing so provide juvenile abalone with both protective shelter and nourishment. ”我们得知urchin会去吃kelp，而正因為(wèi)这个饮食习性，使得幼小(xiǎo)的abalone可(kě)以有(yǒu)庇护所以及营养，但是原文(wén)并没有(yǒu)明确告诉我们kelp在abalone的成長(cháng)过程中到底扮演了什么角色，我们只知道urchin干掉了kelp对abalone有(yǒu)好处，而E没有(yǒu)明确告诉我们decline到底是谁的下降，而要从urchin自身数量下滑推到kelp增加，再推到abalone下降又(yòu)需要几步推理(lǐ)过程，原文(wén)是没有(yǒu)明确指明的，所以E不可(kě)以选择。反观C所言：它们对某一生物(wù)幼崽有(yǒu)作用(yòng)，确实是原文(wén)仅的少量信息里可(kě)以作证的内容，所以zui保险就是选择C。
