什麼是補語

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

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.

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

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