1、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。将疑问句、感叹句等还原成陈述句1. _ when has the country been open to inter
2、national 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 countryhas 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. n
3、ot 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 businessC. So her business was successful D. So was her busi
4、ness successful点拨：选B。该句的正常语序是：Her business 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 hav
5、e 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 now. 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. wateringC. waterD. 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 un
6、less 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)A. not if dealt carefully with B. if not carefully dealt withC. if dealt not carefully with D. not if carefully dealt with点拨：选B。if not carefully dealt with是if the
7、situation is not carefully dealt with的省略形式。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. (2007全国卷)A. like B. as C. or D. but点拨：选D。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i
8、t 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 C. that D. this点拨：选C。强调句型，强调由not . but . 连接的两个并列的主语从句。将被动语态还原成主动语态1. When you get the paper back, pay special attention to what _. (四川2007)A. have marked B. have been
9、 marked C. had marked D. had been marked点拨：选B。还原成主动语态可以清楚地看出“批阅（mark）”的执行者是“老师”，而what是mark的承受者，两者之间为动宾关系或被动关系。2. Professor James will give us a lecture on the Western culture, but when and where _ yet. (浙江2007)A. hasnt been decided B. havent decided C. isnt being decided D. arent decided点拨：选A。when and where hasnt been decided yet还原成主动语态应该是：they havent decided when and where Professor James will give us the lecture。
