(十)消除思维定势

10.Everyone here will thank the firefighter for the things they have done to prevent fires______ the environment safer.

A. make B. to making C. to make D. from making

有些试题的题干，看上去好象就是固定搭配，我们高兴地完成以后，结果却做错了。要从句子结构上或者句子意思上分析，以免步入命题者设计的陷阱。此题容易误选D，以为是考查prevent sb. /sth. from doing 这一固定搭配的。其实，“使环境更安全”是“他们为防火所做的工作”的目的，所以用动词不定式，选C。

(十一)查看有无连词

11.If an excellent Chinese novel is translated into English, ______means many more people in the world can enjoy it.

A. as B. which C. what D. that

若经查实，前后的确是两个句子，就要看其中一个分句是否已经用了连词。若已经用了连词，一般不选连词，若没有用连词，就一定要选连词。此题已有连词If，选D，若没有If，就选B， which引导一个非限制性定语从句。

(十二)正确把握语境

12. I agree with most of what you said, but I don’t agree with ______.

A. everything B. anything C. something D. nothing

有时孤立地看留空格的那个句子，好象多个答案都可以，但与上下句的意思联系起来，就会发现问题。因此，做题时一定要把握语境。此题答案选A。B答案的意思是I don’t agree with anything 等于I agree with nothing.这就与前一分句的意思发生矛盾了。

(十三)识别相似句型

13. ______is known to everybody, light travels much faster than sound.

A. It B. As C. That D. What

14.______is known to everybody that light travels much faster than sound.

A. It B. As C. That D. What

15. _____ is known to everybody is that light travels much faster than sound.

A. It B. As C. That D. What

有的句型十分相似，若不仔细分辨，很容易出错。13题选B，as引导一个非限定性定语从句，先行词是后面整个句子。14题选A，it是形式主语， that引导主语从句;15题在that前加个is，则应选D， what引导的是主语从句， that引导的是表语从句。

四、方法归纳

分析法：分析句子结构或语言习惯，使句子“合法”。

排除法：排除句子中某些附加成分， 使其简单直接。

补全法：补全省略部分，连接思维序列中的断点。

推断法：根据上下文依据，判断空格所依据的信息。

还原法：通过转换句型还原句子本来面目，以便理解句意。
