GMAT阅读是GMAT考试中的一大难点，考生要想获得理想分数就要掌握GMAT阅读的正确解法及备考步骤。下面小编为大家带来的是GMAT阅读的正确复习步骤，希望对大家的阅读备考有帮助。
考生在快速阅读文章时，特别留意段落开头或者结尾可能出现的语气词和过渡词。这样做有助于你对作者思路的把握，从而快速掌握文章大意。考生要在脑子里形成一个文章的结构思路题。各个段落的目的是什么，主题又是什么?不必完全掌握整篇文章，了解文章中的每一个细节。可以只读文章段落的第1句，并快速浏览其余部分。当你“读”完这篇文章时，你就能对文章的结构思路有总体的把握。下面小编将结合具体文章为大家详细介绍一下：
Biologists have advanced two theories to explain why schooling of fish occurs in so many fish species. Because schooling is particularly widespread among species of small fish, both theories assume that schooling offers the advantage of some protection from predators.
Proponents of theory A dispute the assumption that a school of thousands of fish is highly visible. Experiments have shown that any fish can be seen, even in very clear water, only within a sphere of 200 meters in diameter. When fish are in a compact group, the spheres of visibility overlap. Thus the chance of a predator finding the school is only slightly greater than the chance of the predator finding a single fish swimming alone. Schooling is advantageous to the individual fish because a predator’s chance of finding any particular fish swimming in the school is much smaller than its chance of finding at least one of the same group of fish if the fish were dispersed throughout an area……Sometimes, proponents argue, predators simply cannot decide which fish to attack. This indecision supposedly results from a predator’s preference for striking prey that is distinct from the rest of the school in appearance. In many schools the fish are almost identical in appearance, making it difficult for a predator to select one. The second explanation for the “confusion effect” has to do with the sensory confusion caused by a large number of prey moving around the predator. Even if the predator makes the decision to attack a particular fish, the movement of other prey in the school can be distracting. The predator’s difficulty can be compared to that of a tennis player trying to hit a tennis ball when two are approaching simultaneously.
