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. →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.
