非谓语动词
非谓语动词
1
PART ONE
非谓语动词首先是一种动词形式,其次是这种动词形式不能做谓语,综合这两点,我们将其叫做非谓语动词。
非谓语动词的形式非谓语动词包含四种形式,即不定式、动名词、现在分词和过去分词。其中,每种形式按照发生时间和主被动又包括不同的子形式。
定义:
①基本形式:to do(表示主动,并且一般表示将来)
②被动式:to be done(表示被动,并且一般表示将来)
③进行式:to be doing (表示主动和进行)
④完成时:to have done(表示主动和完成)
⑤完成被动式:to have been done(表示被动和完成)
⑥完成进行式:to have been doing (表示主动和完成进行)
不定式:
①基本形式:doing (表示主动)
②被动式:being done(表示被动)
③完成式:having done(表示主动和完成)
④完成被动式:having been done(表示被动和完成)
动名词:
①基本形式:doing (表示主动和进行)
②被动式:being done(表示被动和进行)
③完成式:having done(表示主动和完成)
④完成被动式:having been done(表示被动和完成)
现在分词:
done及物动词的过去分词表示被动或完成;不及物动词的过去分词表示主动或完成。
polluted river 被污染的河流;fallen leaves 落叶
过去分词:
非谓语动词重难点
1. 须用省去to 的不定式(do)作宾补的11个动词。五看(see、watch、notice、observe、look at)两听(hear、listen to)三使(make、let、have)一感觉(feel)根据谐音记忆法,我们可以记做“吾看两厅三室一感觉”。
2. 只接不定式(不能接动名词)作宾语的25个常用动词want、would like、wish、help、hope、learn、manage、offer、plan、afford、agree、arrange、ask、beg、care、choose、decide、demand、determine、expect、fear、prepare、pretend、promise、refuse
3. 只接动名词(不能接不定式)作宾语的28个常用动词practice、consider、enjoy、finish、give up、imagine、keep、put off、risk、suggest、admit、advise、allow、appreciate、avoid、delay、deny、discuss、dislike、escape、excuse、fancy、forbid、mention、 mind、miss、permit、prohibit
4. 既可接不定式也可接动名词,但含义完全不同的8个动词remember to do sth. 记住要做某事(未做) remember doing sth. 记得做过某事(已做)
非谓语动词重难点
非谓语动词解题步骤
1. 判断非谓语动作的逻辑主语,以此来确定它表示主动含义还是被动含义。①非谓动词做定语时,其逻辑主语是它所修饰的名词或代词。②非谓语动作做状语时,其逻辑主语是句子主语。③非谓语动作做宾补时,其逻辑主语是它前面的宾语。
非谓语动词解题步骤
2. 判断非谓语动作与谓语动作的先后关系。和谓语动作同时发生表示进行,应用以上提到的进行式(to be doing和doing);发生在谓语动作之后表示将来,应用(to do和to be done);发生在谓语动作之前表示完成,应用(to have done、to have been done、to have been doing、having done、having been done和done)。

例2._________ many times, he still couldn’t understand it.
A. Having been told B. Having told C.He had been told D. Though he had told
解析:例1中有连词but连接,表明前后都是句子,答案为C。
例2中后面是一个句子,而且没有连词,所以前面不是句子,应该用非谓语动词,根据句意此处为被动,答案为A。
原则一:两个句子必须要用连词连接,如果没有连词连接,则需要用非谓语动词。
例3. ____ in the mountains for a week, the two students were finally saved by the local police.
A. Having lost B.Lost C. Being lost D. Losing
解析:lose为及物动词,现在后面没有宾语,所以用-ed形式,答案为B。

A. Considered all the possibilitiesB. Taking all the possibilities into considerationC. Taken all the possibilities into considerationD. Giving all the possibilities
解析:把…考虑进来结构为take sth into consideration,现在take后面有宾语all the possibilities,所以用-ing形式,答案为B。
原则二:不及物动词无-ed形式非谓语动词,及物动词有宾语时用-ing形式,无宾语时用-ed形式。
例5. to reach them on the phone, we sent an email instead.
