1、巧用还原法快解英语单选题 在英语的单项填空题中，有许多是针对考生解题的思维定势所设计的“陷阱题”。出题人往往通过变化句子结构，把简单的句子改写成一个少见或陌生的结构，来干扰学生的思路，使学生误入“歧途”。对于这类题考生可以反其道而行之，把题干还原为自己所熟悉的结构。这样，题目就会变得简单，答案也就比较容易判定。具体来说，可采用以下几种方法： 一、疑问句改为陈述句 疑问句的使用，使句子的结构变得陌生，考生可将题干还原成陈述句。如： 1. Whom would you rather have _________ with you? A. to go B. go
2、C. gone D. going 分析：将题干还原为陈述句： Would you rather have whom ________ with you. 很容易看出测试的知识点是 have sb. do 结构。答案为 B 。 2. Is this factory _________ you visited yesterday? A. that B. which C. the one D. where 分析：将题干还原为陈述句： This factory is ___________ you visited yesterday. 很容易看出该句缺先行词，所以选
3、“ the one ”。答案选 C. 试比较： Is this the factory _________ you visited yesterday? A. when B. which C. the one D. where 分析：将题干还原为陈述句： This is the factory __________ you visited yesterday. 此句缺定语从句的连接词。答案为 B 。 二 . 陈述句改为倒装句 考生们经常接触的是倒装句，而命题者却有意地使用陈述句来命题。如： We had ______ got home than it beg
4、an to rain. A. no sooner B. hardly C. almost D. nearly 分析：“ no sooner … than ”是考生非常熟悉的一个倒装句型，但命题者却使用了一个陈述句。如果将题干还原为 _________had we got home than it began to rain, 就能很容易地选出答案 A 了。 三 . 倒装句改为陈述句 On the grass _________ two sheep. A. lies B. lie C. laid D. lying 分析：将题干还原为陈述句： Two sheep
5、 _________ on the grass. 答案为 B. 四 . 去掉从句 命题者有时会故意在句子中插入从句造成主谓隔离以增强干扰。如果将从句去掉，题干就会变得很简单。如： 1. The young student did all that he could ________ the examinations. A. pass B. to pass C. passing D. passed 分析： that he could 是一个定语从句。将其去掉就会发现这个句子少了一个目的状语。答案为 B 。 2. The days we look forward
6、 to ________ at last. A. comes B. to come C. came D. coming 分析：本题易被误认为介词 to 的后面要接动名词（即动词 -ing 形式）。实际上 we look forward to 是一个定语从句，介词 to 的宾语为 the days 。去掉这个从句，就可以看出题干中缺少一个谓语。答案为 C 。 3. The country life he was used to _________ greatly since the opening policy. A. change B. has change
7、d C. changing D. having changed 分析：去掉从句 he was used to ，可以看出本题缺少一个谓语。答案为 B 。 五 . 去掉插入语 1. Who do you think _________ us a talk this afternoon? A. to give B. gave C. will give D. giving 分析： do you think 是插入语，把它去掉，答案也就一目了然了。答案为 C 。 2. He believes in himself, ________, in my opinion,
