被动语态基本用法:
当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由“助动词be+过去分词”构成，时态通过be表现出来。
被动语态 (Passive Voice)
结构: be + V-p.p.
am / are / is +动词的过去分词
was / were +动词的过去分词
一般现在时的被动语态:
一般过去时的被动语态:
一般将来时的被动语态:
will / be(am/is/are) going to +动词的过去分词

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
肯定句 主语 + be + 过去分词 + (by…)
A sweet song was sung by her on the stage.
2 否定句 主语 + be + not +过去分词 + (by…)
3 一般疑问句 Be + 主语 +过去分词 + (by…)
A sweet song wasn’t sung by her on the stage.

4 特殊疑问句 疑问词 + be + 主语 +过去分词 + (by…)
