很多刚开始接触GRE 阅读的考生在做多段文章时，常常反馈的自己遇到的困难是觉得文章字太多，看完第二段已经差不多忘了首段的内容。
而这种多段文章又常考察主旨题，很多同学做到这种题目的时候大脑一片空白，基本靠猜。
如果你也面对这样的问题的话，说明你并没有掌握GRE 阅读的一个核心考点，即判断文章主次关系的能力。
在考察文章主旨的时候，GRE 并不是要求大家能记住文章中每字每句的内容，进而自己总结出这些句子的共同点和主旨出来。
而实际是考察给了这么多句子，哪些句子的重要性会比别的句子更重要。换言之，主旨是找出来的，不是总结出来的。
回到我标题问的问题，字多头晕记不住怎么办？记不住说明你尝试记的内容太多了，GRE 并不考察记住所有信息的能力，需要去粗存精。
例
一起来看一篇三段的文章练习下这个能力：
What accounts for the low-lying, flat surface of Mars’s north? On Earth’s surface, higher- and lower-lying areas have different types of crust: one, thin and dense, is pulled toward Earth’s center more strongly by gravity, and the planet’s water naturally comes to sit over it, creating oceans. The processes that generate this oceanic crust drive plate tectonics.
Is Mars’s north similarly characterized by a sort of crust different from other areas of the planet? Some researchers do see signs of tectonic activity surrounding the northern basin that suggest that it was created through the formation of new crust, like ocean basins on Earth. However, McGill points to Northern bedrock structures that predate the features said to mark the start of the tectonic process. McGill instead believes that through some novel mechanism the ancient surface sank to its current depth as a single unit. This would explain why features around the basin’s edge, which would have formed as the surface dropped, seem to be younger than structures at its floor.
The third possibility is that the northern lowlands result from impacts. Some researchers suggest they formed as a series of big overlapping impact craters. Others arguing that the odds against such a pattern of impacts are large, postulate a single event-the impact of an object bigger than any asteroid the solar system now contains.
这篇文章出现了多个理论，而且文中措辞出现了很多天文地理术语，如果追求逐字读懂每个信息显然是非常困难的一篇文章。
但从寻找段落主旨句的角度来说，一段和第三段的主旨句都是很清晰可以快速判断出来的，即分别的一句。
首段提出来全文探讨的话题，什么可以解释火星北部的地表特征？
第三段开头说第三个解释是什么什么。通过第三段首句也可以推测出来，前文肯定是提了另外两个理论。
则全文的主旨结构是很清楚的，是一篇现象解释的文章，且提出了三种解释。
