对于托福阅读来说，内容的阅读还是要建立在托福阅读文章基础上出的题目，那么这就需要各位好好的理解文章后再街托福阅读试题了，那么文章除了要了解意思外还有什么呢?当然是整体结构了了解段落展开方式(paragraph development)对于把握与段落主题有关的修辞目的的托福阅读试题题和文章摘要题非常有效。例如，修辞目的题有时问段落的写作目的，有时问段落的结构，都等于从写作手法，即段落展开方式上问段落主题。现在就跟着百利天下小编一起来学习吧!
很多托福阅读文章段落属于总-分结构，即段落开始为段落主题句，其他部分为支撑细节，具体论证方式有举例、对比比较、定义、分类、提供数据支持、类比、过程描述等，此时的段落目的对应段落开始的主题句。例如，
例一(总-分结构)
Paragraph 7: About 90 percent of modern humans are right-handed: we are the only mammal with a preferential use of one hand. The part of the brain responsible for fine control and movement is located in the left cerebral hemisphere, and the findings above suggest that the human brain was already asymmetrical in its structure and function not long after 2 million years ago. Among Neanderthalers of 70,000–35,000 years ago, Marcellin Boule noted that the La Chapelle-aux-Saints individual had a left hemisphere slightly bigger than the right, and the same was found for brains of specimens from Neanderthal, Gibraltar, and La Quina.
What is the author's primary purpose in paragraph 7?
(A) To illustrate the importance of studying the brain
(B) To demonstrate that human beings are the only mammal to desire fine control of movement
(C) To contrast the functions of the two hemispheres of the brain
(D) To demonstrate that right-hand preference has existed for a long time
托福阅读根据一般段落的总-分结构，可以判断首句为主题句，所以第四个选项为正确答案。文中主要描述大脑左半球的功能，未与大脑右半球的功能进行比较，所以第三个选项为干扰选项。
