被动语态
英语动词有两种语态：主动语态和被动语态 1. 主动句：主语（施动者）+谓动+宾语（受动者）
被动句：主语（受动者）+be 谓动过分+ by+施动者 2. 被动语态的谓语： be动词+ p.p.(过分词） e.g.The school was built last year.学校是去年修的 3. 主动句和被动句的转换方法：
情态动词+ be + done must be done/mustn’t be done should be done/ shouldn’t be done can be done/ can’t be done may be done/ might be done

一.生活中不是每个句子都需要用被动语态表示。像“Basketball was played by动 句用的还是多一些。 什么时候用被动句呢？
三. 1.Was the bag taken by him ? Yes, it is/ No, it isn't. The bag wasn't taken by him.
2. Should the food be eaten ? Yes, it should/ No, it shouldn't 3. Has the work been done ? Yes, it has./ No, it hasn't.
二. 1. The flowers were watered by me. 2. A jacket was bought by her. 3. His clothes are often washed by him. 4. My mother is gong to be visited by me. 5. Basketball can be played by him.
二. 把下列句子变为被动句。
1. I watered the flowers. 2. She bought a jacket.
3. He often washes his clothes. 4. I'm gong to visit my mother. 5. They can play basketball. 6. We should take care of the old people 三. 把下列句子变为疑问句并回答，再变为否定句. 这种变化与以 前学的一样：有be变be动词，有其他助动词则变助动词，有情态 动词则变情态动词
1) A car knocked him down yesterday.
•He was knocked down by a car yesterday． 2) These two kids plant trees every year． Trees are planted by these two kids every year. 3)We should protect the earth．
The earth should be protected by us. 4)We’ll put on the play next Sunday．
The play will be put on next Sunday.
补充作业：
一. 翻译（用被动语态译，注意时态）： 1. 我的红钢笔被他偷了。2. 他的钱已经被用完了。 3. 这辆自行车经常修。 4. 这个房间能使用。 5.这个房子将被卖掉。
基本形式：be+ done (以do为例）
1. 一般现在时：am/is/are
+ done
2.一般过去时：was/were
+ done
3. 一般将来时：(shall/will/be going to) be+ done
4.现在完成时： have/has been
+
done
5. 情态动词： can等 + be
1）.把原来的宾语提到前面作被动语态的主语; 2）.把动词变成“be + 过去分词”; 3）.主动语态中的主语变为介词by的宾语。 e.g. They cleaned the room. 主动句
The room was cleaned by them. 被动句 * 若施动者不重要，by+施动者口语中常省略。 3. 被动语态有各种时态：
Your clothes should be washed. 你的衣服该洗了。
（以上句子中都省略了by+ 施动者）
**可见，被动句的各种时态只变be动词的时态就行，过去分词始 终不变。
