1 2 3

需要掌握的要点:

1、如何判断主动句还是被动句。

2、掌握各种时态的被动形式。

3、主动句与被动句的转换。

  • 1、判断主动句还是被动句的关键是看谓语与主语之间的关系。如果谓语动词所表示的动作是主语发出的是主动句,否则是被动句。

  • 例如:We often play basketball。(此句中的play“打”这个动作是主语we“我们”来完成,因此是主动句。

    • The baby is looked after very well.(此句的主语baby“婴儿”不能完成looked after“照顾”这个动作,而是被别人照顾,因此是被动句。

  • 2.被动语态的形式:

  • 1)被动语态的基本形式为“助动词be + 动词的过去分词”构成即(be done) 。

  • 被动语态的不同时态是通过助动词be的时态变化来体现的,其人称和数方面应与主语保持一致。我们需要掌握的被动句型是:

  • am/is/are+动词的过去分词 (done)

  • 一般现在时的被动语态:

  • 一般过去时的被动语态:

  • 一般将来时的被动语态:

  • 现在完成时的被动语态:

  • 含情态动词的被动语态:

  • was/were+动词的过去分词 (done)

  • will be +动词的过去分词(done)

  • have /has been +动词的过去分词(done)

  • 情态动词+be+动词的过去分词 (done)

  • 2)被动语态的否定式:在第一个助动词后加not构成

  • 例如:The letter was not written last night.

  • 3、主、被动语态的相互转换:

  • 主、被动句的转换可分为三个步骤:

  • 第一步:将主动句的宾语变为被动句的主语。

  • 第二步:将主动句的动词变为被动语态的形式即“be+动词的过去分词”。

  • 第三步:将主动句的主语变为被动句的宾语,前面要加by。

  • 注意:1、by短语可以省略。2、如果是人称代词要相应的变为主格或宾格。如图:

  • 主动句: 主语+谓语+宾语

  • 被动句:

主语

be+过去分词

(+by+宾语)

例如:Luxun wrote the book.

The book

was written

by Luxun.
