中考网整理了关于2020年中考英语知识点之被动语态的结构与应用情况,希望对同学们有所帮助,仅供参考。
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.
