什麼是補(bǔ)語

補(bǔ)語(complement): 補(bǔ)語用於說明主語或賓語。分別稱爲(wèi)賓語補(bǔ)足語和主語補(bǔ)足語。補(bǔ)語例句如下：

He thinks the girl beautiful.

The doctor advised her to have a good rest.

You should get on the plane in turn.

若動(dòng)詞賓語較長，通常用it做形式賓語代替其位置，而將其移至賓語補(bǔ)足語之後：

I found it difficult to finish the task in time.

We have made it clear that we disagreed.

主語補(bǔ)足語：含賓語補(bǔ)足語的句子在轉(zhuǎn)換成被動(dòng)語態(tài)後，原有的賓語和賓語補(bǔ)足語就變爲(wèi)主語和主語補(bǔ)足語。

We found him working in the office. He was found working in the office.
