非谓语动词

非谓语动词包括动词不定式,动词- ing形式和过去分词。非谓语动词没有人称和数的变化,不受主语人称和谓语动词的时态变化干扰,但是有时态和语态的变化。非谓语动词在句中不能单独作谓语,但仍保留动词的特点,即可以有自己的宾语和状语。

To hear your voice is so nice. 动词不定式

Reading books makes one wise. 动词-ing形式

This is a book written by Balzac. 过去分词

1、 动词不定式

作主语

To learn a foreign language is not easy.

作宾语

He wants to buy some stamps.

作宾语补足语

The doctor told me to have a rest.

作定语

I want something to eat.

作状语

Yesterday they came to visit us.

动词不定式的时态和语态

一般式:to do表示不定式的动作发生在谓语动词的动作之后,或同时发生。

I want to visit my teacher.

I believe him to be a good studeng.

完成式:to have done 表示不定式的动作发生在谓语的动作之前。

I am sorry to have kept you waiting for a long time.

进行式:to be doing 表示不定式的动作与谓语的动作同时进行。

He seems to be worrying about it.

被动语态:to be done 表示被动关系。

This sick man will need to be taken to a hospital.

有些动词的不定式省略to.

祈使动词如make, let , have

The boss made Tom’s father work all day.

感官动词如hear, see, notice

I saw him go into the classroom just now.

用于被动语态时,被省略的to需要还原

He was made to do the job at once.

*不定式省略to的口诀

有些动词跟不定式作宾语补足语时省去了to,其口诀是:一感二听三让四观看。

一感:feel

二听:hear, listen to

三让:let, have, make

四观看:observe, see, watch, look at

动词不定式的否定需在to前加not。

2 动词-ing形式

动词-ing形式是动词的另一种非限定形式,包括现在分词和动名词两种,有动词原型加-ing构成。

动词-ing形式作主语的情况

动词-ing形式作主语,有时也可以用it作形式主语,而把动词-ing形式放在后面。

Reading poetry brings people from different places and different times together.

It’s useless arguing with him.

在下面这些词后常接动词-ing形式作宾语。

mind 介意 finish 完成 consider 考虑 miss 错过

enjoy 喜欢 practice 训练 keep 坚持 appreciate 欣赏

2.3 动词-ing形式放在系动词后作表语

2.4动词-ing形式在一些动词后作宾语补足语

动词-ing形式在listen to, hear, watch, notice, feel, find, leave, look at, have等动词后作宾语补足语,表示动作正在进行。

They left the fire burning all day long.

Do you notice him writing something there?

The policeman caught him stealing the bike.

I heat him singing in the next room.

2.5动词-ing形式作定语的两类情况

我们常说的动名词作定语,用来修饰无生命的名词,且只能前置;这类定语不能改为名词从句。

A teaching building 教学楼 A walking stick 拐杖 A swimming pool 游泳池

A sleeping bag 睡袋 A smiling face 笑脸 A reading room 阅览室

我们常说的现在分词作定语,多用来修饰有生命的名词(有时也可以用来修饰无生命的名词)。这类定语,如果动词-ing形式是单独修饰名词,常前置;如果动词-ing短语修饰名词,则常后置,它们都可以被改为定语从句。

The dancing girl (The girl who is dancing) is my classmate.

The new hospital being built (which is being built) is just near our school.

动词-ing形式作状语

这类结构常用来表示时间、原因、条件、结构。它相当于一个状语从句,其逻辑主语就是主语的主语;也可置于句尾,表示伴随、补充说明。

动词-ing形式作状语表示时间

Hearing the good news (= When they heard the good news), the students were wild with joy.

Having watered the vegetables ( = After they had watered the vegetables), they went back home for

breakfast.

动词-ing形式作状语表示条件

Standing on the top of the tower (= If we stand on the top of the tower), we can see as far as the Yangtze

River.

动词-ing形式作状语表示自然而然的结果

Her husband died in 1942, leaving five children with her(= and left five children with her).

动词-ing形式作状语表示伴随或补充说明

Every evening they sat on the sofa watching TV(= and watched TV).

过去分词

过去分词作前置定语

单个的过去分词或带副词的单个过去分词作定语时,放在所修饰词的前面,为前置定语,具有形容词的特点。

A broken window

A recently-built house

A newly-married couple

过去分词作后置定语

有时为了强调,过去分词作定语时要置于被修饰的名词之后,作后置定语,此时过去分词既有形容词的特征,又有动词的特征。

He is a man loved and respected by all.

过去分词作定语与定语从句的关系

及物动词的过去分词可以改为动词为被动形式的定语从句;部分不及物动词的过去分词作定语时,可改为动词为完成式或动词为表示状态的定语从句。

A returned scholar = a scholar who has returned

The first textbooks written for teaching English ( = which were written for teaching English) as a foreign

language came out in the 18th century.

The computer center opened last year(= which was opened last year)is very popular among the students in

the school.

过去分词作表语表示主语所处的状态

He was terrified at seeing this scene.

The door remained unlocked.

过去分词作表语与被动状态的区别

过去分词作表语表示主语的特点或所处的状态,被动语态则表示一个被动的动作。

The cup is broken.(过去分词表状态)
