阅读理解解题策略——搭配段落与主题
在阅读当中，要把段落与主题进行正确搭配，同学们必须理清段落结构，了解段落大意。段落与主题之间的搭配练习可以很好地培养大家的结构认知能力和归纳概括能力。

【搭配方法】
一、认真阅读每一个段落, 找出段落主题句。
段落的大意主要由主题句来体现，因此识别各段落的主题句相当重要。主题句一般会出现在：
1. 段落首句。请看下面的例子：
Our life today depends very much on energy. In towns and in villages, on farms and in factories, machines have made life easier than it used to be. The machines use energy, and energy is needed for heating and lighting in daily life. Factories and industrial plants use a great deal of energy to make the things that we need.
这段文字所讲的主要是能源问题。第一句概括性地提出“我们目前的生活很大程度上依赖于能源”。而随后出现的三句都是具体事例，对第一句进行说明。
2. 段落尾句。请看下面的例子：
Now let’s look at an interesting example with color. If you own a blue car, you know it is blue, even it is in bright sunlight, in darkness or under a yellow street light. Your eyes tell you that it changes color in these different situations, but your brain knows better. You have learnt that cars don’t change color, and your brain interprets (解释) the information your eyes give you.
这段文字所讲的是眼睛和大脑对于颜色的辨别。主题句为your brain interprets the information your eyes give you，前面有关蓝色汽车的例子是为说明这一观点服务的。
3. 逻辑连词处, 尤其是表示因果和转折的连词。常引出主题句的逻辑连词有：therefore, so, but, however, in short等。请看下面的例子：
The modern Olympic Games were founded with the intention of improving health and education, promoting world peace and encouraging fair and equal competition. But over the years, the Olympic saying, “Faster, higher, stronger”, has pushed scientists as well as athletes to do everything possible to reach new levels.
该段首先谈到的是奥运会的宗旨，随后用But转折，引出新的话题——奥运会的口号使得科学家和运动员尽一切努力让运动员提高成绩。因此，主题句为But后面的内容。
二、从每段中找出关键词, 看关键词是否与所给主题有重复信息。这个重复信息通常就是该段的中心话题。
三、阅读所给主题, 并将它们和各段搭配。
四、确定与任何一段都不能搭配的多余主题。
