-初中英语被动语态的教案-第 3 页被动语态授课人： 授课时间：一、 语态概述 英语中有两种语态：主动语态和被动语态。 主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。 例如：Many people speak English. 谓语：speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。例如：English is spoken by many people.主语English是动词speak的承受者。He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句) 判断：你来判断哪个是主动哪个是被动？ We call the doctor. People dont play football here. The truck was cleaned yesterday. Mr Chen teaches us English. The classroom was cleaned. 二、被动语态的构成：be+动词的过去分词+by sb（be+done) 一般现在时：amisaretaught 一般过去时：wasweretaught 一般将来时：willshall betaught 现在进行时：amisare beingtaught 过去进行时：havehas beentaught 现在完成时：havehas beentaught 含有情态动词的被动语态：can/may/must/should. +be done 歌诀是：被动语态be字变，过去分词跟后面。三、 主动变被动的方法 口诀：主变宾，宾变主，By 句尾跟 Be 字变，Vpp跟后面一、选择题（2×15=30分）一、选择题（2×15=30分）( )1._ a new library _ in our school last year?A.
