主语谓语动词主动语态的过去式宾语主语谓语动词被动语态的过去分词介词+宾语主动句变为被动句所遵循的4个步骤：1.把原主动句中的宾语变为被动句的主语。2.把动词变为被动形式即be+过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。3.原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。4.其它的成分（定语、状语）不变。被动语态的几种句型

主语+be+not+过去分词+(by…)3一般疑问句

Be+主语+过去分词+(by…)?Asweetsongwasn’tsungbyheronthestage.Wasasweetsongsungbyheronthestage?4特殊疑问句

疑问词+be+主语+过去分词+(by…)?Wherewasasweetsongsungbyher?一般讲，被动语态可用于英语的各种时态。为了能准确地运用被动语态，重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下：

1、一般现在时的被动语态：am/is/are+动词的过去分词

Ourclassroomiscleanedeveryday.ThiscarismadeinChina.

2、一般过去式的被动语态:was/were+

动词的过去分词

Hisdeskwascleanedjustnow.

Thestationwasbuiltin1928.

一般现在时：am/is/are+vt.p.p.

一般过去时：

was/were+

vt.p.p.

一般将来时:

willbe/begoingtobe+

vt.p.p.

情态动词：must/can/could/may+be+

vt.p.p.现在进行时:

be(am/is/are)+being

+

vt.p.p.现在完成时:

have/has+been

+

vt.p.p.被动语态的构成：be

+vt.p.p.被动语态：当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者时，或者只需强调动作的承受者时，要用被动语态。何时使用被动语态？何时使用被动语态？主语是动作的承受者。
