备战职称英语考试:重点语法解析(1)

发布时间:2016-03-01  编辑:查字典英语网小编

  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.

  被动语态考点聚焦

  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.

  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:

  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 meon my birthday.

  I was given an interesting book on my birthday.

  ②主动变被动时,宾补成主补;不定式前需加to.

  The boss made him work all day long.

  He was made to work all day long

  ③短语动词变被动语态时,勿要掉尾巴.

  The children were taken good care of .

  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:谓语动词用被动语态,动词不定式作主补.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
