直接引述別人的原話，叫做直接引語;用自己話轉述別人的話，叫做間接引語。間接引語一般構成賓語從句。直接引語必須放在引號內，間接引語則不用引號。直接引語改為間接引語時，除將引語部分變成賓語從句外，還必須對直接引語中的人稱、時態(tài)、指示代詞、時間狀語、地點狀語等進行改變。

一、不定式做主語：

1、不定式做主語一般表示具體的某次動作。===動名詞doing表示習慣的，經常的動作。

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

To do such things is foolish.

To see is to believe. (對等)

注: 1).不定式作主語時,謂語用單數

2).當主語較長，謂語較短時，常用it做形式主語，而將不定式放到謂語的后面。

it做形式主語，不定式放在謂語動詞之后常用于下列結構中：

(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 +名詞+ 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均可作表語，但possible可以用不定式作真實主語，而probable不能用不定式作真實主語。

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

It is possible for him to come to the meeting.

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