2. They managed _____the meeting room before the guests arrived. (C)
A. finishing to clean B. finishing cleaning
C. to finish cleaning D. to finish to clean
1. ______won't be of much help. (A)
A .Tom's going B. Tom going C. Tom to go D. Tom goes
2. ______for two hours , he went away .
A. waiting B. to wait C. waited D. Having waited
句1表示“站在那等”,两个动词同时发生,故选A作伴随状语。
句2表示已经等了两个小时,发生在谓语动词“went away ”之前,故用完成式,选D 。
需要注意的是,非谓语动词的否定也是常考的项目,要认清否定形式,非谓语动词的否定都应将not 放在前面。
如:
What is the reason for ______there?
A. not your going B. not your go C. your not going D. you not to go
巩固练习:
1. He stood there ______for his mother .
3. The building ______last year is a restaurant.
A. having been built B. to be built
C. being built D. built
句1中 now 说明大楼正在被修,故用进行式,选C。
句2中next year 说明大楼将在明年被修,故用表将来的不定式,选B。
句3中 last year 说明大楼已被修,但不能选,因为现在分词的完成式不能作定语,故用过去分词,选D。
又如:
2. The building ______next year will be a restaurant .
1. The building ______now will be a restaurant .
4. ______ the dirty clothes, the girl hung them up outside.
A. was washed B. washed C. were washed D. having washed
分析:句3. 前面应用非谓语动词作句子的状语,逻辑主语是“the dirty clothes”,和动词搭配表示“衣服被洗”,故选B。
句4. 逻辑主语为句子的主语“the girl”,表示“女孩洗衣服”,为主动关系,故选D。
3. The dirty clothes ______ , the girl hung them up outside .
2.______from space , we can see the earth is blue .
A. Seen B. Seeing C. To see D. See
这两个题选项中的非谓语动词都没有加自己的逻辑主语, 因此其逻辑主语就是句子的主语。
分析:句1. “地球”被“看起来”,表被动,故选A,用过去分词表被动。
句2. 我们“主动看……”即表主动,故选B。
