GMAT阅读问题求解考试题型的文章开始提出一个问题或设置一个困难/任务，然后给出解决方案，文章围绕这些问题展开讨论分析，并把作者的观点态度贯穿其中，所以如何解答这种题型呢?本文就给大家介绍下GMAT阅读文章—问题解决型解答技巧。
一、考察形式
1、首先，问题解决类的文章通常会以问句的形式开始提出一个问题或设置一个困难/任务，第一段会提出一个问题或者呈现一个难题，而问题通常是“设问”句。常见的标志词如：problem，difficulty, task, puzzle, challenge, question等词。
例如：All of the cells in a particular plant start out with the same complement of genes. How then can these cells differentiate and form structures as different as roots, stems, leaves, and fruits?
2、紧接着，会对这一问题进行解答或作出解释，给出解决方案，文章围绕这些问题展开讨论分析，并把作者的观点态度贯穿其中。主要考察考生对文章问题的理解以及对所给答案的分析和判断，要求考生有明确的思路和方向。
例如：The answer is that only a small subset of the genes in a particular kind of cell are expressed, or turned on, at a given time. This is accomplished by a complex system of chemical messengers that in plants include hormones and other regulatory molecules. Five major hormones have been identified: auxin, abscisic acid, cytokinin, ethylene, and gibberellin. Studies of plants have now identified a new class of regulatory molecules called oligosaccharins.
二、应对方法：
这类文章的大体结构基本可以总结为“提问-解答-表明立场”，明白这一点，在读文章的过程中就要学会善于分析并把握文章的重点，判断作者最想表达的内容。这样在做题的时候就能做到心中有数，镇定自若，在提高做题速度的同事也能保证较高的正确率。

三、真题解析
After evidence was obtained in the 1920s that the universe is expanding, it became reasonable to ask: Will the universe continue to expand indefinitely, or is there enough mass in it for the mutual attraction of its constituents to bring this expansion to a halt? It can be calculated that the critical density of matter needed to brake the expansion and “close” the universe is equivalent to three hydrogen atoms per cubic meter. But the density of the observable universe—luminous matter in the form of galaxies—comes to only a fraction of this. If the expansion of the universe is to stop, there must be enough invisible matter in the universe to exceed the luminous matter in density by a factor of roughly 70.Our contribution to the search for this “missing matter” has been to study the rotational velocity of galaxies at various distances from their center of rotation….(OG13/23)
首先，正如上文介绍的，文章一开始作者先提出了文章围绕的问题：宇宙是继续扩大呢?还是有足够的物质能够让它停止扩大?(Will the universe continue to expand indefinitely, or is there enough mass in it for the mutual attraction of its constituents to bring this expansion to a halt?)。接着，作者给出了解答这个问题的重要信息：宇宙中存在的无形物质的密度必须超过发光物质的密度，宇宙才有可能停止扩大(If the expansion of the universe is to stop, there must be enough invisible matter in the universe to exceed the luminous matter in density by a factor of roughly 70.)文章第二段，作者开始探讨这种无形物质到底是否存在?答案是：存在。最后作者对第一段的问题做出回答：“不确定”以此来表明作者的观点和立场。
