英语被动语态语法讲解
初中被动语态语法讲解
(一)?语?态?分?类
英语动词有两种语态.，主动语态和被动语态。as brought his book here. His book?has been brought?here.
(四）含有情态动词的被动语态：含有情态动词的被动语态是由“情态动词+ be+?及物动词的过去分词”构成。
(1)You?must hand in?your homework after class. Your homework?must be handed in?after class.
(2)He?can write?a letter with the computer. A letter?can be written?with the computer by him.
(五)?被?动?语?态?的?使?用
，常用被动语态，这时往往不用by?短语。
??“Mr. White, the cup was broken after class. ”

→???A special class to help poor readers was set up?in the school.
。
+?过去分词，时态要与原句保持一致。
?的宾语，放在被动语态里谓语动词之后，by?短语可以省略。如果原句主语是地点名词，在被动语态中用in +?地点名词作状语。
(七)语态转换时所注意的问题
1.?把主动语态变为被动语态，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。We have bought a new new computer has been bought.?A new computer have been bought.??(错误)
