.主动语态与被动语态：
英语动词有两种语态,即主动语态(The Active Voice)与被动语态（The Passive Voice)。
主动语态表示主语是动作的执行者;
被动语态表示主语是动作的承受者。
主动语态
被动语态
主动语态
被动语态
e.g Many people speak English.
主动语态变被动语态的步骤：
1、主动语态的宾语变为被动语态的主语；
2、主动句的谓语动词变为被动结构；
3、主动句的主语变为被动句的宾语，由by 引出，当不强调动作的执行者时，常省略。
4.其它成分不变。
变被动语态时需要注意的事项
一变
二套
三注意
宾变主，主变宾，宾语前面by跟，谓语动词变过分，不忘前面be动词跟
套时态，主被动时态一致
注意因人称的变化而引起的主谓一致问题。
各种时态的被动语态的构成：
1.一般现在时态 am, is, are +过去分词
2.一般过去时态 was, were +过去分词
3.一般将来时态 will/am.is.are going to
+ be +过去分词
4.过去将来时态 would/was.were going to
+ be + 过去分词
5.现在完成时态 have, has + been +过去分词
6.过去完成时态 had + been +过去分词
7.现在进行时态 am, is, are + being +过去分词
8.过去进行时态 was, were + being +过去分词
9.含情态动词的 情态动词 + be +过去分词
所有时态的被动语态否定就是在
最前面的助动词后加 not
疑问就是把最前面的助动词提前。
Many trees are not being planted now

2、People used wood for making tables.

3、They are making computers in the USA.
