单项填空解题技巧之“简化还原法”

单项填空解题技巧之“简化还原法” 单项填空是高考英语试题的基本题型之一，用来考查词法、句法、惯用法、交际用语、词语辨析等各项内容。在做单项填空题时，除应具有较扎实的语言基础知识外，掌握一些解题方法也是很有必要的。

简化还原法我们平时见到的句子大多是以陈述语序出现的。因此，遇到疑问句、感叹句、倒装句、强调句等相对陌生的句式时，我们不妨先把它们还原成陈述语序；遇到省略句时，我们可以根据上下文把省略的部分还原，这样，句子结构就清晰了；并列句、复合句看似复杂，但通过简化，问题自会迎刃而解。

1.—_____ when has the country been open to international trade?

—1978, I suppose. 陕（西2007）

A.Since

B. In

C. From

D. After

点拨：选 A 。结合答语，疑问句可还原成：The country

has been open to international trade since 1978. 现在完成时与since 引导的时间状语连用。

2.—Robert is indeed a wise man.

—Oh, yes. How often I have regretted __ his advice! （安徽2007）

A.to take

B. taking

C. not to take

D. not taking

点拨：选D。感叹句可还原成：I have often regretted not taking his advice. regret

接动词-ing 形式作宾语，表示对过去所做的事感到后悔。

•将倒装语序还原成正常语序

1. ___ that Marie was able to set up new branches elsewhere.（陕西2007）

A.So successful her business was

B.So successful was her business

C.So her business was successful

D.So was her business successful

点拨：选B。该句的正常语序是：Her bus in ess was so successful that Marie was able to set up new branches elsewhere在so ... that …句型中，当“ so + adj. / adv” 位于

句首时，主句需部分倒装。

2.I have been living in the United States for twenty years, but seldom __ so lonely as now. （辽宁2007）

A. have I felt

B. I had felt

C. I have felt

D. had I felt

点拨：选 A 。还原成正常语序，后一分句应该是：I have seldom felt so lonely as n ow. seldom是含有否定意义的副词，用于句首时，句子需部分倒装。

•将省略句还原成完整的句子

1.The flowers his friend gave him will die unless every day. （四川2007）

A. watered

B. watering

C. water

D. to water

点拨：选A。还原成完整的句子，该句就应该是：The flowers his friend gave him will die unless the flowers are watered every day. 当状语从句的主语与主句的主语一致时，从句的主语和be动词可以省略。

2.We all know that, _____ , the situation will get worse. （2007 全国卷I ）

A.not if dealt carefully with

B.if not carefully dealt with

C.if dealt not carefully with

D.not if carefully dealt with

•将强调句式简化成一般句式

1.Between the two generations, it is often not their age, their education that causes their misunderstanding. （200全国卷I ）

A. like

B. as

C. or

D. but

点拨：选Do强调句型的基本句式是：it is / was +被强调部分+ that +句子的

其它成分。通过简化，去掉it is / was ... that,就成了一般句式。该句中，如果将

it is及that去掉，我们就不难看出，这句话强调的是由not ... but…连接的并列主语。

2.It is not who is right but what is right is of importance. （重庆2007）

A. which

B. it
