二、精典名题导解
选择填空
1. _________ is a fact that English is being accepted as an international language.(NMET 1995)
A.There B.This C.That D.It
解析:答案为D。本题考查作形式主语的用法。that引导的从句是真正的主语。为避免头重脚轻而平衡句子结构,将it置于句首作形式主语。
2. I hope there are enough glasse for each guest to have ________.(NMET 1995)
A.it B.those C.them D.one
解析:答案为D。本题考查替代词it和one的区别。it用于替代同类的、特定的、同一的事物;one替代同类的、泛指的人或物。根据题意“我希望有足够的杯子使每个客人有一个。”可知应用one泛指enough glasses中的一个。
3. Was __________ that I saw last night at the concert?
A.it you B.not you C.you D.that yourself
解析:答案为A。本题考查强调句型的疑问式。只须将句序变为陈述句便不难得出答案。
4.It was back home after the experiment.
A. not until midnight did he go B. until midnight that he didn’t go
C. not until midnight that he went D. until midnight when he didn’t go
解析:答案为C。此题考查的是not…until句型的强调结构,其最根本结构是:He did not go back home after the experiment.①,把①转变为Not until midnight did he go back home after the experiment.②,注意②中的倒装结构,把②中划线部分放在强调结构It be 被强调部分that…中进行强调,但注意that从句后面不用倒装形式。
