考生在备考GMAT阅读时经常会因为没有掌握解题策略而严重失分，导致最后得分不理想。接下来小编为大家带来的是GMAT阅读解题策略讲解，希望对大家的阅读备考有帮助。
例如，OG13阅读解析-22：While the most abundant and dominant species within a particular ecosystem is often crucial in perpetuating the ecosystem, a “keystone” species, here defined as one whose effects are much larger than would be predicted from its appearance, also play a vital role. But because complex species interactions may be involved, identifying a keystone species by removing the species and observing changes in the ecosystem is problematic….
Moreover, whereas P. ochraceus occupies an unambiguous keystone role on wave-exposed rocky headlands, in more wave-sheltered habitats the impact of P. ochraceus predation is weak or nonexistent, and at certain sites sand burial is responsible for eliminating mussels. Keystone status appears to depend on context, whether of particular geography or of such factors as community diversity (for example, a reduction in species diversity may thrust more of the remaining species into keystone roles) and length of species interaction (since newly arrived species in particular may dramatically affect ecosystem). 更多相关内容请点击》GMAT阅读如何读懂文章。
111. The passage mentions which of the following as a factor that affects the role of P. ochraceus as a keystone species within different habitats?
(A) The degree to which the habitat is sheltered from waves
(B) The degree to which other animals within a habitat prey on mussels
(C) The fact that mussel populations are often not dominant within some habitats occupied by P. ochraceus
(D) The size of the P. ochraceus population within the habitat
(E) The fact that there is great species diversity within some habitats occupied by P. ochraceus。更多相关内容请点击》GMAT阅读满分备考方案。
第一步，利用题干中的关键词进行回文定位。
在这道题目中通过the role of P. ochraceus as a keystone species可以定位本题答案在第二段，定位到Moreover, whereas P. ochraceus occupies an unambiguous keystone role on wave-exposed rocky headlands, in more wave-sheltered habitats the impact of P. ochraceus predation is weak or nonexistent。
第二步，了解答案所在段落的结构。所谓的段落结构值得是段落的中心思想以及段落是如何展开的。了解段落的中心思想可以帮助考生对于段落整体进行把控，然后再进行题目分析，保证题目的正确率。同时还可以对阅读中文章内容小节题做准备。
(A) 通过定位处可知影响紫海星基础物种地位的由栖息地避浪性决定，正确。
(B) 文中指出它是由在栖息地内其他蚌类的程度决定，不正确。
(C) 文中指出蚌类数量在紫海星为主体的栖息地并不占主导地位，错误。
(D) 在栖息地内紫海星的数量，错误。
(E) 在蚌类占主导地位的栖息地物种多样性存在，错误。更多相关内容请点击》GMAT阅读文章思路分析。
第三步，掌握不同题型的解题方法
GMAT阅读理解考察的是考生的答题能力而非阅读能力。考生不必完全掌握整篇文章，了解文章中的每一个细节。对于GMAT阅读部分的七大题型，考生只需要掌握每种题型对应的解题方法，能够快速选出正确答案即可。另外，对于阅读过程中碰到的一些关键地方，比如数据，例子，关键词等，要有一定的敏感度，因为这些地方往往就会是之后出题和答题的关键点，发现这些关键之后最好做一下标记，以便之后做题的时候容易找到需要精读的地方。更多相关内容请点击》GMAT阅读高分经验分享。
