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 / ashame / 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.

一、过去分词
过去分词兼有动词、副词和形容词的特征,可以带宾语或受状语修饰。过去分词和宾语或状语一起构成过去分词短语。它在句中可以作定语、表语、宾语补足语或状语。这节课讲解作定语、表语的用法。
1. 作定语
作定语的过去分词如果是单词,一般放在被修饰词的前面;过去分词短语作定语,一般放在被修饰词的后面。例如:
There are many fallen leaves on the ground.
This is a book written by a worker.
2. 作表语
过去分词作表语,多表示主语所处的状态。
I was pleased at the news.
The door remained locked.
过去分词作表语,相当于形容词,常见的有:delighted, disappointed, astonished, interested,satisfied, surprised, tired, worried, excited, married 等。
过去分词作表语时,应注意与被动结构的区别。系表结构说明主语的状态或具有的性质、特点;被动结构强调谓语动作。
The small village is surrounded by trees.(状态)
The small village was soon surrounded by enemy soldiers.(动作)
I'm interested in chess.(状态)
3. 过去分词做状语
①表时间,相当于一个时间状语从句,有时过去分词前可加连词 when 或 while 来强调时间概念。
