高中英语第一轮复习：非谓语动词
非 谓 语 动 词
非谓语动词就是不能充当句子谓语成分的动词形式，包括动词
不定式（to do）、分词（过去分词 V-p.p.、现在分词 V-ing）、动名词
V-ing 三种形式。
一、 动词不定式
1、 基本形式：to do (有时 to 可以省略，称为不带 to 的不定
式)
2、 特点：没有人称和数的变化，也不受谓语动词时态变化的
干 扰 eg: I(You/He/She/We/You/They)
want(wants/wanted) fdfddd
dddd to buy a car.
3、 动词不定式可充当的句子成分
作主语
eg: To study hard is our duty.
常使用 it 作为形式主语，不定式作真正主语放后面
It is not easy to master a foreign language.
亦可在不定式前面加上 for sb.指出不定式的逻辑主语
It is not easy for us to master a foreign language.
但某些表示人的品行的形容词，如：
kind/good/nice/right/wrong/wise/unwise/polite/impolite/
rude/silly/stupid/foolish /careless/clever/thoughtful 等作表
语时改用 of sb.
It is kind of you to help me with my study.
作宾语
eg: I want to borrow your dictionary.
能直接跟不定式作宾语的动词
有want/like/hope/wish/prefer/hate/decide/expect/desire/
try/manage/start/begin/remember/forget/ask/offer/
continue/agree/choose/pro-mise/mean/pretend 等
常使用 it 作为形式宾语，不定式作真正主语放后面
I find it interesting to study English.
作表语
也就是放在连系动词（主要有 be 动词 am/ is/ are、感官动词
look/ hear/ smell/ taste/ feel、表示保持和变化的动词 stay/
keep/ remain/ become/ turn/ grow/ get 以及 seem 等）的后
面。
eg: Her wish is to become a doctor.
She doesn’t seem to like the idea.
作定语 动宾关系
eg: Here are some books (for you to read).
She has a sick baby (to take care of).
Have you got anything to say? Vt.或短语动词（Vi.+介
词）
The nurse has five children to look after.
She was the first person to think of the idea.
作状语
1. 作目的状语
eg: To catch the first bus, I have to get up early.
He went home to see his parents.
She uses a computer to write an article.
另外不定式作目的状语常用 so as to(只能放句中) / in order
to
