.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。
e.g. 1.They make trains in Zhuzhou .
主动语态
被动语态 主动语态
Trains are made in Zhuzhou.
2.The farmers grow cotton every year.
Cotton is grown by the farmers every year.被动语态
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 出，当不强调动作的执行者时，常省略。 4.其它成分不变。 e.g Many people speak 引
三、注意动词短语的 完整性
• 常考到的动词短语有
• take care of • look after • listen to • speak to eg. 1.We should speak to the old politely. The old should be spoken to politely. 2. The nurse takes good care of the baby. The baby is taken good care of by the nurse.
四、无被动语态的动词。

4、They have grown rice in South China.

English.

变被动语态时需要注意的事项

• 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：
5. We must plant more trees next year.
More trees must be planted next year.
6.I am going to clean our classroom tomorrow.
Our classroom is going to be cleaned tomorrow.
Sth+be+ 过去分词+ for/to sb+ by sb. Sb + be+ 过去分词 sth + by sb
二、无to不定式
变为被动时加上to
• 一感 • 三让 • 四看
feel listen to.hear let.have.make watch. see.look at. notice
二听
所有时态的被动语态否定就是在ห้องสมุดไป่ตู้最前面的助动词后加 not
Many trees are not being planted now
疑问就是把最前面的助动词提前。
Are many trees being planted now?
