初中英语语态讲解

语态知识梳理 知识点1：被动语态的构成 一般式 进行式 完成式 现在时 am/is/are+p.p am/is/are+being+ p.p have/has+been + p.p 过去时 was/were+ p.p was/were+being+ p.p had +been + p.p 将来时 shall/will+be+p.p shall/will+have been+ p.p 注意：含有情态动词的谓语变化为被动语态时，由“情态动词（can, may must, have to等）+be +动词的-ed形式。含有“be going to , be to, used to, be about to”等结构的复合谓语变为被动语态时，其构成为“be going to （be to, used to, be about to）+ be +动词的-ed形式”构成。 知识点2：几种特殊形式的被动语态的构成 1．短语动词的被动语态 通常只有及物动词才有被动语态，但有些短语动词相当于及物动词，可以有被动语态，但短语动词是一个不可分隔的整体，变为被动语态时不可去掉构成短语动词的介词或副词。 Have you sent for the doctor?→Has the doctor been sent for? 注意：主动结构的谓语动词为“不及物动词+名词+介词”构成的及物的短语动词时，通常把它看成一个整体。但也可将这类短语动词本身的名词用作主语，构成被动语态，尤其是在名词前有定语修饰时。 Good care must be taken of the babies particularly while they are ill.
