1、 GrammarThe passive voice被动语态语态(voice)是个语法范畴，它是一种动词形式，表示动词的主语与该动词所表示的动作之间的主动和被动关系。当主语是动作的执行者时，动词用主动语态（Active Voice）；如果主语是动作的承受者，动词便用被动语态（Passive Voice）。We cleaned the classroom yesterday.昨天我们打扫了教室。The classroom was cleaned by us yesterday.昨天教室被我们打扫了。一、被动语态的定义：We speak English.主语谓语宾语English is spoken
2、by us.主语谓语宾语主动语态被动语态动词的被动语态由“助动词be+及物动词的过去分词”构成。当主动句变为被动句时，原来的宾语变成了主语，原来的主语变成了介词by 的宾语。主动句与被动句的结构虽然不同，但动作的执行者和承受者的关系并没有改变。二、被动语态的一般结构：即：be+done(+by)在被动句中有时用by-词组，有时不用。一般来说，当动作的执行者为谁不甚清楚，不甚重要或难以说出时，通常不用by。但有时为了强调动作执行者或者由于上下和结构上的需要则必须使用 by 词组。例如：Hamlet was written by Shakespeare.哈姆雷特是莎士比亚写的。The task h
