(1) 由于介詞后通常不能直接跟that從句作賓語,有個別特殊結構就在介詞后先接it作形式賓語,再跟that從句:

You may depend on it that he will turn up in time. 你可以相信他會及時趕到的。

I can’t answer for it that the boy is honest. 我不能保證這個男孩是誠實的。

I’ll see to it that all these letters will be sent to the post before twelve. 我將注意讓所有的信件在12點以前送到郵局。

【注】① 在其他情況下解決介詞后跟that從句的辦法是借用the fact作賓語:

They were worried over the fact that you were sick. 他們為你生病發愁。

個別介詞(主要是butexcept)也可接that從句作賓語:

I know nothing about him except that he lives next door. 我只知道他住在隔壁,其他的就不知道了。

(2) 有的動詞由于通常只用作及物動詞,當它們后接if從句或when從句,通常應先在動詞后接it作形式賓語:

She won’t like it if you arrive late. 她不喜歡你遲到。

He hates it when people use his bike. 他討厭別人用他的自行車。

I hate it if you say such things in public. 我討厭你在大庭廣眾之下說那樣的事。

I’d prefer it if I didn’t have to do so much work. 要是我不必做那么多工作,那就太好了。

I would appreciate it very much if you would help me with it. 如果你能幫助我做這事,我會十分感激。

【注】能這樣用的動詞不多,主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示情緒的動詞。而且高考對此也有所考查,請看一道高考真題(答案選A)

I hate ______ when people talk with their mouths full.

A. it                          B. that                      C. these                    D. them

(3) 用于 have it that(說,認為)take it that(認為)等個別固定表達中:

I take it (that) you agree. 我以為你同意了(www.52ysedu.com)

Report has it that about 30 people were killed in the accident. 據報道,在這次事故中大約有30人喪命。

六、用于強調句型

1. 基本句型結構

it用于強調句的基本句型結構是:It+be+被強調部分+that(who)+其他部分。請看用例:

It was in the Japan that he died. 他是死于日本。

It was yesterday that he got married. 他是昨天結婚的。

It was a computer that he bought last week. 他上個星期買的是一臺電腦。

2. 使用強調句型應注意的幾點

(1) 強調主語時,that后謂語動詞的數應與被強調的主語保持一致:

It is I who am right. 是我對。

It was you that were wrong. 是你錯了。

(2) 不要想當然地用he, she, that等代替強調句中的it

_____ was in this room that he was killed.

A. It                         B. That                     C. He                        D. Who

此題答案應選A。該句還原成非強調句為He was killed in this room.

【注】有關強調句型的其他用法說明,參見本講義強調句型
