當(dāng)不定式、動(dòng)名詞、從句等復(fù)雜成分用作賓語(yǔ)且其后跟有賓語(yǔ)補(bǔ)足語(yǔ)時(shí)，通常會(huì)在賓語(yǔ)補(bǔ)足語(yǔ)前使用形式賓語(yǔ)it，而將真正的賓語(yǔ)移至句末，其基本結(jié)構(gòu)為“動(dòng)詞+it+賓語(yǔ)補(bǔ)足語(yǔ)+不定式(動(dòng)名詞或從句)”。如：

I find it difficult to do the job well.

我發(fā)現(xiàn)做好這件事不容易。

I think it best that you should stay here.

我認(rèn)為你最好住這兒。

We think it no use complaining.

我們認(rèn)為抱怨是沒(méi)有用的。

但是，以下幾種形式賓語(yǔ)比較特殊，同學(xué)們需引起注意(同時(shí)它們也是高考的常考考點(diǎn))：

1. 動(dòng)詞+ it + that-從句。如：

I like it that you came. 你來(lái)了，我很高興。

I take it (that) he will come on time. 我認(rèn)為他會(huì)準(zhǔn)時(shí)來(lái)的。

You can put it that it was arranged before. 你可以說(shuō)這是以前安排的。

Rumor has it that the defence minister will soon resign.

據(jù)傳聞，國(guó)防部長(zhǎng)不久就要辭職。

說(shuō)明：能用于此結(jié)構(gòu)的動(dòng)詞不多，常見(jiàn)的有 have, take, put, like 等。

2. 動(dòng)詞 + it + when (if)-從句。如：

I dislike it when you whistle. 我不愛(ài)聽(tīng)你吹口哨。

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，好就太好了。

說(shuō)明：能用于此結(jié)構(gòu)的動(dòng)詞不多，常見(jiàn)的有 enjoy, hate, love, like, dislike, appreciate, prefer 等。

3. 動(dòng)詞 + prep + it + that-從句。如：

See to it that you’re not late again. 注意千萬(wàn)不要再遲到。

Look to it that this doesn’t happen again. 注意不要再發(fā)生這種事。

I can’t answer for it that he will come. 我不能保證他會(huì)來(lái)。

You may rely on it that he’ll come to meet you. 你放心，他會(huì)來(lái)接你的。

說(shuō)明：能用于此結(jié)構(gòu)的動(dòng)詞不多，常見(jiàn)的有see to, look to, insist on, stick to, depend on, answer for 等。

4. 動(dòng)詞 + it + 介詞短語(yǔ)+ that-從句。如：

I owe it to you that I am still alive. 多虧有你我才仍然活著。

I took it for granted that he would help us. 我認(rèn)為他會(huì)幫助我們的。

說(shuō)明：能用于此結(jié)構(gòu)的動(dòng)詞不多，常見(jiàn)的有take it for granted, bring it to sb’s attention, owe it to sb 等。
