Unit5What arethe shirtsmade of主动语态和被动语态

1.在英语中，动词有两种语态，即主动语态The ActiveVoice和被动语态The PassiveVoiceo主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者eg:Many peoplespeak English.主动语态English isspoken bymany people.被动语态2一般现在时被动语态的构成当谓语是一般现在时的时候，被动语态由〃be am,is,are+及物动词的过去分词”构成助动词“be〃随人称、数的变化而改变egThis knifeis madeof woodand metal.Bananas areproduced inHainan.T amtaken careof by my uncle.

3.被动语态的用法当说话者不知道动作的执行者或没有必要指出动作的执行者，只需要强调动作的承受者时，要求使用被动语态如果需要在被动语态中指出动作的执行者时由介词by引导egChinese isspoken bythe largestnumber ofpeople inthe world.全世界说中文的人最多

4.主动语态改写成被动语态的方法将主动语态的宾语变成主语，将主动语态的谓语变成被动式be+过去分词，主动语态的主语变成被动句by的宾语或省略如果主动语态中有两个宾语直接宾语和间接宾语，可以把其中任意一个变成主语eg:My teachergives mea lot of books.主动语态I amgiven alotof books bymy teacher.A lotofbooksare givento mebymyteacher.单元语法精练
