一、不定式做主语：

1、不定式做主语一般表示具体的某次动作。===动名词doing 表示习惯的，经常的动作。

e.g: To finish the building in a month is difficult.

To do such things is foolish.

To see is to believe. (对等)

注: 1). 不定式作主语时,谓语用单数

2). 当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。

it做形式主语，不定式放在谓语动词之后常用于下列结构中：

(1)It is/was +adj.+of sb. to do…

(2) It is +adj.+for sb.+to do…

It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary

(3) it is +a +名词+ to do...

It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do

It takes (sb.) some time / courage / patience …to do…

It requires courage / patience / hard work… to do…

_注意: probable 和 possible 均可作表语，但possible可以用不定式作真实主语， 而probable不能用不定式作真实主语。

It is probable for him to come to the meeting.(错)

It is possible for him to come to the meeting.

It is possible / probable that he will come to the meeting.

二、不定式做表语

主语是以aim duty hope idea intention plan job suggestion wish purpose task 等为中心词的名词词组 或以 what 引导的名词性从句表示，后面的不定式说明其内容, 不定式作表语常表示将来或现在的动作或状态。

eg :My idea is to climb the mountain from the north.

Your mistake was not to write that letter.

What I would suggest is to start work at once.

三、动词不定式作宾语

以不定式结构为宾语的动词有：

ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用动词不定式作宾语

口诀(接不定式作宾语的动词)

想要学习 早打算( want learn plan)

快准备 有希望( prepare hope wish expect)

同意否 供选择(agree offer choose)

决定了 已答应(decide be determined promise)

尽力去 着手做(manage undertake)

别拒绝 别假装(refuse pretend)

语法总结

过去分词作定语和表语

一. 过去分词作表语

作表语用的过去分词表示主语的特点或所处的状态，相当于形容词，强调主谓关系;被动语态表示动作，强调动宾关系,绝大多数被动结构中的行为执行者还可以用by短语来表示。

1. 过去分词做表语与被动语态的差异:

The store is now closed.(系表)

The library is usually closed at 8:00 p.m. (被动)

2. 某些过去分词作表语，多半用来表示人物所处的心理状态或情感变化, 其主语主要是人。

这类过去分词通常为下列过去分词: delighted, devoted, discouraged , astonished, frightened, excited, inspired, encouraged, interested, contented, pleased, puzzled, satisfied, tired, worried, ect .

二. 过去分词作定语

作定语的过去分词相当于形容词，其逻辑主语就是它所修饰的名词。及物动词的过去分词作定语，既表被动又表完成;不及物动词的过去分词作定语，只表完成。

1. 过去分词用作定语，如果是单个的，置于其所修饰的名词之前。

We must adapt our thinking to the changed conditions.

我们必须使我们的思想适应改变了的情况。

2. 过去分词短语用作定语时，置于其所修饰的名词之后，其意义相当于一个定语从句，但较从句简洁，多用于书面语中。

The concert given by their friends was a success.

他们朋友举行的音乐会大为成功。

3. 过去分词短语有时也可用作非限制性定语，前后常有逗号。

The meeting，attended by over five thousand people，welcomed the great hero.

他们举行了欢迎英雄的大会，到会的有五千多人。
