2020年中考英语知识点之被动语态的结构与应用情况

来源:101教育网整理 2020-02-04 字体大小: 分享到:

 

 如果你觉得现在走的很辛苦,那证明你在走“上坡路”,101教育初中小编整理了2020年中考英语知识点之被动语态的结构与应用情况内容,以供大家参

  ①基本结构:

  肯定句式:be +done (及物动词的过去分词)

  如果是不及物动词 + 相应的介词或副词

  否定句式:be +not +done

  疑问句式:be动词(情态动词)放句首

  被动语态中的be为助动词,无意义。be可能是am , is , are也可能是was ,were或原形be。

  注:☆被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be后面的过去分词不变。

  Eg:

  1.The song is liked by young people. (肯定句)

  2.The song isn’t liked by young people.(否定句)

  3. Is the song liked by young people ?(一般疑问句)

  4.Who is the song liked by ?=By whom is the song liked?(特殊疑问句)

  ②各种时态的构成(动词以do为例):

  →一般现在时

  动词的被动形式:am/is /are done

  例句:He is asked to do this.

  →一般过去时

  动词的被动形式:was/were done

  例句:The story was told by her mother.

  →一般将来时

  动词的被动形式:will /shall be done

  Is/are going to

  例句:The problem will be discussed tomorrow.

  →过去将来时

  动词的被动形式:should/would be done

  Was/were are going to

  例句:He said the trees would be planted soon.

  →现在进行时

  动词的被动形式:am/is/are being done

  例句:The novel is being written.

  →过去进行时

  动词的被动形式:was/were being done

  例句:At that time the desk was being made.】

  →现在完成时

  动词的被动形式:has/have been done

  例句:The house has been built.

  →过去完成时

  动词的被动形式:had been done

  例句:They said that their work had been finished.

  含有情态动词的被动语态:情态动词+be+ done Your homework must be handed in today.

  其它几种特殊句型:

  It is said that ……..

  It is well known that …….

  It is reported that……

  例:

  ①History is made by the people. (一般现在时)

  ②The cars were made in Tianjin in 1995. (一般过去时)

  ③The tree will be cut down next year.(一般将来时)

  ④The room must be kept clean.(含有情态动词的被动语态)

  ⑤The door is being opened.(现在进行时)

  ⑥The film has been seen by me.(现在完成时)

  注:☆不同时态的被动语态的差异主要体现在助动词be的变化上,同时助动词be还要在人称和数上与主语保持一致。

  ③应用情况

  行为的执行者不明确或不必说出来。

  Eg: A stranger was killed last night.

  用于强调动作的承受者而不是执行者。

  Eg: The story is told everywhere in the city.
