这是非谓语动词讲解的一部分

关于逻辑主语的问题动名词复合结构的一般规则是：

1.逻辑主语是有生命的名词：作主语时，须用名词所有格或形容词性物主代词；作宾语时，也可用普通格或人称代词宾格。

Tom s (His) coming is what we have expe

2. 逻辑主语是无生命的名词：Is there any hope of our team winning the match

She didn t mind Jack/ Jack s (him/ his) coming here.

1. ______to the meeting surprised all of the boards.

A. Mike coming B. Mike came

C. Mike comes D. Mike s coming

2. It s no use _______ that you didn t know the rules.

A. you pretend B. you pretending

C. your pretending D. your pretend

Change the following into the simple sentences. 不定式、动名词用作主语

1。直接作主语

（1）眼见为实

（2）今天早晨做早操对身体无益

（3）在这里吸烟很危险

1.To see is to believe

2.To do morning exercises today is not good for health.

3.To smoke here is dangerous

（1）眼见为实。

（2）天天做早操有益于健康。

（3）吸烟不是好习惯。

1.Seeing is believing.

2.Doing morning exercises every day is good for health

3.Smoking is not a good habit

A: 如果要说明不定式表示的动作是谁做的，

可以在不定式前加一个由 for 引起的短语。

It is easy for the students to read.

It will be a mistake for us to help you.

B: 下列形容词作表语时，不定式前常加一个 of 引起的短语，这些形容词是：

(表评价性的，来说明逻辑主语的性质，特征，属性）

kind, good, nice, wise, unwise, clever, silly, stupid, foolish, wrong, right, careless, rude, polite,naughty etc. It s kind of you to think so much of us.

It s unwise of him to leave home at once.

It s wrong of him to speak bad behind others.

It s wrong of the south to break away from the Union.

动名词作主语用it作形式主语，有自己特定的句型

2.用it作形式主语，常与no use,no good,useless, worthwhile连用

1.It’s no use talking too much without doing anything

2.It’s useless crying over the spilt milk

3.It’s no good smoking too much

4.It’s worthwhile learning English well.

1. It s no use ______( sit ) here waiting.

这是非谓语动词讲解的一部分

2. There is no ______( say )what will happen next.

3. Is it any good ______( tell ) him the truth?

4. It is great fun _____ (play) golf.

小结：动名词与不定式作主语时的区别

一、对称原则 主语和表语对称

二、特殊表达 动名词表示经常性、反复发生的动作

不定式表示具体的、某一次的动作

三、固定句型It takes sb some time to do sth

四、习惯用法It s no use/no good /useless/worthwhile + doing …

It s kind/wise/clever… of sb to do sth

It s important/necessary/hard …for sb to do sth

作表语

to do 表示具体的动作，-ing form表示泛指的动作，通常

1. Her work is ______( look ) after the

children.

2. My aim is ______( go ) to TsingHua

University.

3. One of my bad habits is ______(bite )

nails（指甲）.

（3）做表语：主语+系动词+不定式

1). 其主语多为抽象名词(wish, need) 2).be to do可构成将来时态,表 “准备/打算/计划/需要”;

It was about to leave when it started to rain.

2。不定式作主语用it作形式主语，有自己特定的句型

1.It is very kind of you to say so.

2.It’s very foolish of him to say such things

3.It is necessary for us to learn English well

4.It’s not difficult for you to learn well English grammar

3.固定句型

1.It takes LiLei two and a half hours to complete his homework.

2.How long did it take you to finish writing your composition?

不定式动词在介词but，except，besides后面时，如果这些介词之前有行为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to。

She could do nothing but cry．

What do you like to do besides swim?

I have no choice but to go．

(4)作定语

不定式作定语时， 通常放在被修饰的名词或代词之后。不定式常和它所修饰的词有动宾关系。如： I have a lot of work to do. Here are some books for you to read.

She was the first person to think of the idea.

1). 目的状语: 可放于句首,也可放于句末, 前面可加in order/so as/so…as to表强调. He went to see the artist himself. 2). 结果状语:主要用在enough to/too…to…/only to结构中。 3). 原因状语: 主语+系动词+adj.+ to do

表感情的adj.有: happy, surprised, pleased, glad, sorry, anxious(忧虑), disappointed, careful, afraid, wrong. I’m very sorry to see you.

动词不定式的时态和语态

动词不定式保留了动词的一些特征，具有时态和语态的变化，但是它的时态和语态只有以下几种，见下表。

When I got home, my son happened to be watching TV.

如果不定式的动作发生在谓语动词之前，要用完成式.

She is said to have read thirty novels this year.

This novel is said to have been translated into French.
