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.

2)　as, though 引导的倒装句

as / though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。

Child as /though he was, he knew what was the right thing to do.

= Though he was a small child, he knew what was the right thing to do.

注意： a.　句首名词不能带任何冠词。

.　句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。

替换：no matter what = whatever

o matter who = whoever

o matter when = whenever
