　　通常来讲，任何一个阶段不管长短都会涉及疑问的一个方面，也就是说每个阶段通常要围绕一个主题展开。如东一句，西一句，文章的头绪就不会明晰，读者也就无从捉住要点。托福白话阶段不管长短都会有阐明主题的语句，咱们称它为主题句(Key Sentence / Topic Sentence)。捉住主题句就等于捉住了阶段的基地。因此，精确判别并找出主题句适当主要。主题句通常会出如今段首或段尾，起概括全段的作用。托福白话主题句也能够出如今段中，一起还能够首尾呼应，阶段结束时再次着重本阶段的基地思想。

　　例1：阅览下面的阶段：

　　Now let’s look at an interesting example with color. If you own a blue car, you know it isblue, even it is in bright sunlight, in darkness or under a yellow street light. Your eyes tell youthat it changes color in these different situations, but your brain knows better. You have learntthat cars don’t change color all time, and so your brain interprets the information your eyesgive you.

　　主题句在段尾：“你的大脑在解说你的双眼传递给它的信息。”前面有关蓝色轿车的比如恰是为阐明这一观念服务的。

　　主题句当然能够极好地向读者阐明阶段的基地思想，但阅览中咱们常常会发现，有时很难在详细的方位找到一个显着的能阐明主题的语句。这时就需要咱们对阶段的整体内容进行概括总结，高度概括提炼出它的基地思想。

　　留意到了托福 白话主题句的方位，捉住了主题句，就等于捉住了阶段的基地思想。除此之外，阅览时还应留意一些进一步概括总结的词汇和短语的运用以及别的一些遣词，由于这些词的运用能够就啥是主题为读者供给有用的头绪。

　　例2：阅览下面的阶段：

　　Students today socialise in ways quite unlike those of their parents. One of the primarydifferences is the use and abuse of drugs. During the ‘60s and ‘70s, students were known tosmoke the odd joint and occasionally take harder substances, whereas according to recentpolls, students today are using ever larger quantities of drugs on an ever more regular basis.Whilst cannabis is still the drug of choice among young people, synthetic drugs such asecstasy and harder drugs such as cocaine and even heroine are being taken by an increasingnumber of students. Drugs are much more readily available to students and are much cheaperthan ever before.

　　段首句为主题句：“Students today socialize in ways quite unlike those of their parents.”它揭示了这段的基地思想是“如今的学生以一种不同于他们父母所选用的方式进行着社会活动。”余下的各个语句都是以详细的案例来支撑阐明这一基地论点的。

　　例3：阅览下面的阶段：

　　We surveyed local residents in three university towns throughout the state to find out theiropinions on the students in those towns. We questioned over three thousand people andfound that since our last survey three years ago, attitudes towards students have changedconsiderably. “Lazy,” “scruffy” and “bad-mannered” was how more than 40% of thosequestioned described students, up from 22% in the last survey. This year only 25% consideredstudents to be “polite” and “friendly” compared with 39% three years ago. Overall, 49%considered students to be a positive part of the town compared to 58% last time.
