第一部分 语法专题突破
专题十二 非谓语动词
知识导图
考 点 精 讲
考点 1 动词不定式(6年5考)
1. 基本形式:to+动词原形,有时可以不用to,to为不定式符号,本身无意义。其否定结构为:not+to+动词原形。动词不定式没有人称和数的变化。
2. 基本用法
(1)作主语(2015.43)
不定式作主语时,往往用形式主语it代替,而将真正的主语放在句末,避免句子头重脚轻。如:
To learn a foreign language is not easy.
=It is not easy to learn a foreign language. 学习一门外语并不容易。
拓展 It代替不定式作形式主语的句型
①It is +adj.+of sb. to do sth. “某人做某事真是……了”
②It is +adj.+for sb. to do sth. “对某人来说做某事怎么样”
③It's one's turn to do sth. “轮到某人做某事了”
④It takes/took sb. some time to do sth. “某人花(了)多长时间做某事”
(2)作宾语(2016.43)
不定式一般用在及物动词后作宾语。其后跟补足语时常用it作形式宾语,而将不定式后置。如:You may find it useful to draw a timeline and write notes about each event. 你或许会发现画一个时间表和记录每一个事件是很有用的。[八(下)Module 10 P82](it是形式宾语,不定式to draw a timeline and write notes about each event是真正的宾语,useful是宾语补足语)
常见接动词不定式作宾语的有(v.+to do sth.):
agree同意
afford负担得起
would like想要
decide决定
expect期望
hope/wish希望
want想要
learn学习
manage完成;应付
begin开始
prepare准备
promise承诺
pretend假装
plan计划
refuse拒绝
(3)作宾语补足语(2017.39)
①在“动词+宾语+不定式”结构中,不定式作宾语补足语。变为被动语态时,宾语补足语相应地变为主语补足语。如:
It allows people to get closer to them. 这使人们能更加接近他们。[八(上)Module 6 P46]
→People are allowed to get closer to them.
常见接动词不定式作宾语补足语的有(v.+sb. to do sth.):
tell告诉
ask要求
invite邀请
warn警告
want想要
teach教
allow允许
force强迫
expect期望
help帮助
advise建议
persuade说服
②使役动词let, make, have和表示感官的动词see, hear, watch, notice, feel等后要用不带to的不定式作宾语补足语(2017.39)。但是,当上述动词变为被动语态时,其后的to要补上。如:
We often hear her sing. →She is often heard to sing by us.我们经常听见她唱歌。
【速记口诀】
一感(feel), 二听(listen to, hear),
三让(let, make, have),
四看(look at, see, watch, notice)。
(4)作定语
动词不定式作定语时,放在被修饰的名词的后面,作后置定语。如:
I don't have a partner to practise speaking English.我没有一个可以和我一起练习说英语的同伴。
(5)作状语(2019.35,2014.44)
不定式作状语主要表示原因、目的和结果等。如:
I'm sorry to hear you were ill.听到你病了的消息我感到难过。(不定式表原因)
To arrive on time, he got up very early.为了按时到达,他很早就起床了。(不定式表目的)
She is old enough to travel all by herself.她已经到了可以独自旅行的年龄了。(不定式表结果)
拓展 动词不定式的特殊句型
①It's time to do sth.是做某事的时候了。
②too...to... 表示“太……而不能……”。
③...enough to... 表示“……足够……”。
④prefer to do sth. rather than do sth. 表示“宁愿做某事而不愿做某事”。
⑤had better+(not)+省略to的不定式,表示“最好(不)做……”。
⑥Will/Could/Would you please+省略to的不定式?表示“请你做……好吗?”。
⑦Why don't you +省略to的不定式?=Why not +省略to的不定式?表示“你为什么不……?”。
考点 2 动名词(2019.40,2015.39)
