[单元语法]

v.-ing形式的被动语态
1.________in a famous university is what most students wish for. A.To educate B.Educated

C.Being educated D.Educating

解析:选C。考查非谓语动词。该结构的逻辑主语是下文中
的“most students”,所以应用被动形式,故排除A、D;由句子 结构分析,空格部分在句子中作主语,故只能选C。

目录

2.(2013· 福建省龙岩市高三第一次质量检查)________ in the leg made it impossible for me to walk as fast as usual. A.Being injured B.To be injured

C.Having injured D.Injured 解析:选A。考查非谓语动词。此处缺少主语,而现在分词和 过去分词不能作主语,排除C项和D项;B项不定式表示未发生

的动作,与语境不符。据此选A项,用动名词短语作主语。

目录

me.The more I think of them,the more questions I think of

more questions________.由此可知设空处需要用不定式作
more questions的定语。
目录

4.(2013· 辽宁大连双基测试)—What in the world put you in a really bad mood? —________in the traffic for hours.

A.Stuck
C.To be stuck

B.Being stuck
D.Sticking

解析:选B。句意:——到底是什么让你心情特别不好?— —交通堵塞几个小时了。根据问句的what可知,此处需要主 语,排除A项;不定式表示将来,排除C项;stick与“我”之间为

被动关系,所以选B项(动名词的被动式)作主语。

目录

5.—What made little Tom so unhappy and cry in his room?
—________to go hiking with his brother. A.Having not been allowed B.Not having allowed C.Having not allowed

D.Not having been allowed
解析:选D。非谓语动词的否定式not应该放在其前,而且句 中指小汤姆不被准许和他的哥哥一起去远足,故应该使用被 动结构,所以D项正确。
