今天，我们与广大考生分享历年职称英语考试中常考的几类语法最后一类——被动语态，被动语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态;如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。

　　新东方在线网络课堂职称英语辅导团队现将职称英语考试中被动语态的知识点、考点等总结如下，希望考生能达到全面熟悉和熟练运用，以帮助大家提高考试成绩。

　　一、被动语态考点聚焦

　　(一)被动语态的概念：

　　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)。

　　(二)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。

　　(三)被动语态的基本用法：

　　(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。

　　⑤当句子的谓语为say、believe、expect、think、know、write、consider、report等时，被动语态有两种形式：(A)谓语动词用被动语态，动词不定式作主补。(B)用it作形式主语，真正的主语在后面用主语在后面用主语从句来表示。如：

　　People say he is a smart boy.

　　It is said that he is a smart boy.

　　He is said to be a smart boy.

　　People know paper was made in China first.

　　It is known that paper was made in China first.

　　Paper was known to be made in China first.

　　类似句型有：It is said / known / suggested / believed / hoped/ thought that …
