为提高考生们GRE阅读逻辑题复习技巧，本文接下来重点为各位考生就和前程百利小编一同来学习GRE阅读主旨题型的星座解析!在十二星座中，狮子座是最具有权威感与支配能力的星座。与之相匹配的就是GRE阅读中的主旨题。所谓主旨题就是整篇GRE阅读文章的精髓或者说是行文脉络，考查考生对于文章逻辑的把握能力。其表现形式主要有三种：内容性主旨题、架构性主旨题和其他主旨题。此类型的考题和十二星座中的狮子座一样。通常需要考生对整篇文章的组织结构和内容有充分的了解和把握。
主旨型考题通常以下面几种方式出现：
The primary purpose of the passage is to… (内容性主旨题)
The author is primarily concerned with… (内容性主旨题)
Which of the following best states the central idea of the passage? (内容性主旨题)
Which of the following statements best describes the organization of… (架构性主旨题)
Which of the following is the most accurate description of the organization of…? (架构性主旨题)
Which of the following is the most appropriate title for the passage? (其他主旨题—文章标题题型)
The passage would be most likely to appear as a part of… (其他主旨题--文章段落、句子作用题)
下面我们看一篇有关内容主旨的题型：
Because of its accuracy in outlining the Earth's subsurface, the seismic-reflection method remains the most important tool in the search for petroleum reserves. In field practice, a subsurface is mapped by line arranging a series of wave-train sources, such as small dynamite explosions, in a grid pattern. As each source is activated, it generates a wave train that moves downward at a speed determined uniquely by the rock's elastic characteristics. As rock interfaces are crossed, the elastic characteristics encountered generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments.
The seismic records must be processed to correct for positional differences between the source and the receiver, for unrelated wave trains, and for multiple reflections from the rock interfaces. Then the data acquired at each of the specific source locations are combined to generate a physical profile of the subsurface, which can eventually be used to select targets for drilling.
The passage is primarily concerned with
(A) Describing an important technique
(B) Discussing a new method
(C)Investigating a controversial procedure
(D)Announcing a significant discovery
(E)Promoting a novel application
题目要求是对于文章主要介绍内容的选择。那么看题干就知道这是一道有关内容性的主旨题。那么首先要寻找文章的主题句，作者在文章的首句就提出了这个篇内容的主旨——the seismic-reflection method remains the most important tool in the search for petroleum reserves.主要讲述的是 “地震反射法”在实地作业中是探寻石油储存的最主要的工具。接下来排查五个选项，发现A描述的是一项重要的技术，符合主题句改写所以是正确答案。
以上介绍的是GRE阅读主旨题型的星座解析。有关于其他类型的主旨题型，其解题方案很相似，都是通过寻找文章的主旨句，然后进行分析排除错误选项。所以在GRE考试中，如果你能同狮子座一样对文章有很好的掌控欲，紧紧抓住文章的主题句，那么在你应对GRE阅读十二星座之主旨星的时候，肯定能够所向披靡，获得傲人成绩。
