Thepassivevoice被动语态语态是表示主语与谓语的关系的。如果主语是动作的执行者，动词要用主动语态；反之，如果主语是动作的承受者，动词就要使用被动语态。被动语态谓语部分结构为助动词be+过去分词。

各种句型的被动形式肯定句主语+be+过去分词+（by…）否定句主语+benot+过去分词+（by…）一般疑问句Be+主语+过去分词+(by…)?特殊疑问句疑问词+be+主语+过去分词+（by…）？注意：这里be的形式决定了被动语态的时态，其后的过去分词没有变化。重点内容

被动语态的用法1.不知动作执行者时,常用被动语态.eg.Mybikewasstolenyesterday.ThiscarismadeinAmerican.2.不必要说出动作执行者时,常用被动语态。eg.Romewasnotbuiltinaday.3.为了突出强调动作的承受者时,常用被动语态.eg.Thousandsofbeachesarepolluted.

1.PrintingwasintroducedintoEuropefromChina.2.WhowasthefilmtheGoldenCompassdirectedby?3.Heisthoughttobeagoodteacher.4.SheisreputedtobethebestsingerinEurope.印刷术是由中国传入欧洲的。《黄金罗盘》是由谁执导的？他被认为是个好老师。据说，她是全欧洲最好的歌唱家。
