被动语态由“助动词be+及物动词的过去分词”构成。其人称、数和时态的变化都是通过助动词be的不同形式表现出来的。一般现在时的被动语态的谓语形式为“am/is/are+及物动词的过去分词”。This jacket is made f cttn.Many trees are planted by us every year. Tea is grwn (by peple) in Hangzhu.
English is spken by many peple.They aren’t allwed t g int the huse.Is the car made by a Japanese cmpany?
一般现在时的被动语态的句式结构
（1）当动作的执行者不必或不易说出时，用被动语态。The flwers are watered every mrning. （2）需要突出动作的承受者时，用被动语态。动作的执行者由by引出，置于谓语动词之后。The new teacher is liked by all the students.
（3）表示“据说，据报道；人们相信”等时，常用“It is +过去分词+ that从句”句型。It is believed that bth f the chairs were repaired by him.（4）文章的标题、广告、新闻等用语也常使用被动语态。Teachers Wanted. (省略了are) 招聘老师。
（1）系动词get、turn、becme、seem、lk、sund、smell、taste、feel等后接形容词作表语时，用主动形式表示被动含义。That dg lks dangerus.（2）动词need、want、require以及短语be wrth 等后接动词-ing时，用主动形式表示被动含义。My flwers need/want watering. This bk is well wrth reading. 这本书很值得一读。
不能使用被动语态的情况
（3）某些表示主语内在“品质”或“性能”的不及物动词，如write、wash、sell、read、clean、cut等，当它们的主语为物时，用主动形式表示被动含义。This kind f skirt sells well here.（4）不及物动词或词组没有被动结构，如：take place “发生”，happen “发生”，break ut “爆发”， appear “出现”， disappear “消失”，last “持续”等。
主动语态转化为被动语态的步骤
（1）确定主动句的主语、谓语和宾语。
（2）把主动句里的宾语变为被动句里的主语，若主动句里的宾语是人称代词，要将宾格变为主格。
（3）把谓语变成被动结构“be+动词的过去分词”，但时态不能改变。
（4）把主动语态中的主语放在介词by后作宾语，若主语是人称代词，应把主格变为宾格。
