2011年高考英语语法专题知识必考点冲刺归总：动词的被动语态

被动语态的构成方式：be + 过去分词，口语只也有用get / become + 过去分词表示。被动语态的基本用法：不知道或没必要提到动作的执行者是谁时用被动语态。强调或突出动作的承受者常用被动语态（by短语有时可以省略）。

（1）使用被动语态时应注意的几个问题。

①主动变化被动时双宾语的变化。看下列例句。

My friend gave me an interesting book on my birthday.

An interesting book was given to me(by my friend)on my birthday.

I was given an interesting book (by my friend)on my birthday.

②主动变被动时，宾补成主补（位置不变）；（作补语的）不定式前需加to。

The boss made him work all day long.

He was made to work all day long(by the boss)

③短语动词变被动语态时，勿要掉“尾巴”。

The children were taken good care of (by her).

Your pronunciation and spelling should be paid attention to.

④情态动词和be going to、be to、be sure to、used to、have to、had better等结构变被动语态，只需将它们后面的动词原形变为be +过去分词。
