非谓语动词 非谓语动词指的是在句中起名词,形容词或副词作用的动词形式,而不是作谓语的动词形式。 动词的非谓语形式分为动名词,分词,动词不定式。 V2z
动名词
一 动名词-ing作主语
动名词-ing和动词不定式to do都可以作主语,但是在以下的句型中只能用动名词作主语。
It is / was no use /good
not any use /good + doing sth.
of little use /good
useless
若主语和表语都是非谓语动词,应保持形式上的一致。
Seeing is believing.
To see is to believe.
二 动名词 作宾语
以下动词或动词词组常用动名词作宾语
Mind, finish, enjoy, image, keep, practice, suggest, miss, consider, prevent, advise, give up, can’t help, insist on, devote to, look forward to, feel like, be used to, pay attention to等等。

解析:选D “我们的班长建议对这个题目进行讨论。” “suggest”后跟动名词作宾语。
三 下列动词或词组既可以跟动名词作宾语,也可以跟不定式作宾语,但是它们的意义不一样。

四 动词need , require , want 作“需要”解时,其后必须用动名词的主动形式或被动形式作宾语,表示事情需要做。这时动名词的主动式表示被动意义。Be worth 后必须用动名词的主动形式表示被动意义。此外,若动词need表“需要”,require表“要求”,want 表“想要”这些意义时,其后必须接名词或代词作宾语,然后接不定式作宾语补足语。
need / require / want doing / to be done
sb. to do sth.
be worth + n. (表示钱数或相当于钱数的名词)
doing
be worthy of being done
of + n. 值得
to be done
例如: The book is worthy to being read.
The book is worthy to be read.
五 动名词做状语,可以做时间状语,原因状语,条件状语, 让步状语,伴随状语等。

动词不定式
一 不定式做主语
1 可以直接放在句首
To play basketball is a pleasure to me.
2 可以用it作形式主语,而把真正的主语不定式置于谓语动词之后。
It is a pleasure for me to play basketball
It takes half an hour for me to go to school from home .
注意:句型 It is + adj. + for (of ) sb. to do sth用法.
It is very important for us to learn English.
二 不定式做宾语
1 动词不定式跟在以下词后做宾语agree , ask , desire , fail , refuse , intend , plan , manage , decide 等。
2 动词不定式作介词的宾语,一般用于“疑问连词wh- +不定式”结构。
We should take the advise on how to learn maths.
但是在表示“除外”的but , except等少数介词的后面,可用带to的不定式。其前如有实义动词“do”字样时,不定式的符号 “to”需省略。
He had no choice but to work hard.
She did nothing but cry.
3 动词不定式可以直接放在动词之后,也可以使用形式宾语 ,并把真正的宾语放在宾语补足语之后。
I don’t think _____ possible to master a foreign language without much money.
A this B that C its D it
解析:选D 不定式短语“to master a foreign language ”在句中做真正的宾语,因它带有自己的补足语“possible”,故必须用形式宾语it。
4 在感官动词或使役动词feel , see , smell , let , have等后,作宾补的不定式不带to。
但是使役动词和感官动词用于被动结构时,要用带to 的不定式 做宾补。
John was made _____ the truck for a week as a punishment.
A to wash B washing C wash D to be washing
解析: A 句中的谓语“was made ”为被动结构,其宾补应带“to”的不定式to wash。
三 动词不定式做目的,原因状语
The Bismarck sailed into the Atlantic ocean to cut off American supplies to Britain. (目的状语)
动名词做目的状语时,不定式可以变成 “ in order ( not ) to do”, “so as ( not ) to do.
He is playing basketball in the playground to relax himself. (原因状语)
