二、 怎样把主动语态改成被动语态?
把主动语态改为被动语态非常简单，可以遵循以下几个步骤：
1. 先找出谓语动词；
2. 再找出谓语动词后的宾语；
3. 把宾语用作被动语态中的主语；
4. 注意人称、时态和数的变化。
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week. 布鲁斯每星期写一封信。
2. Li Lei mended the broken bike this morning. →The broken bike was mended by Li Lei this morning. 李雷今天上午在修理坏的自行车。

4. They will plant ten trees tomorrow. →Ten trees will be planted by them tomorrow. 他们明天将要种植十棵树。
5. Lucy is writing a letter now. →A letter is being written by Lucy now. 露西正在写信。
6. You must lock the door when you leave. →the door must be locked when you leave. 当你离开的时候你必须把门锁上。
三、 使用被动语态应注意的几个问题：
1. 不及物动词无被动语态。
What will happen in 100 years？一百年里会发生什么事？
The dinosaurs disappeared about 65 million years ago. 约65万年前恐龙灭绝。
2. 有些动词用主动形式表示被动意义。
This pen writes well. 这支钢笔很好写。
This new book sells well. 这本新书卖的很好。
3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带to ，但变为被动语态时，须加上to。
例：Make somebody do something →somebody+ be +made to do something
See somebody do something →somebody +be +seen to do something
A girl saw my wallet drop when she passed by. →My wallet was seen to drop by a girl when she passed by. 一个女孩看到我的钱夹掉了，当她经过的时候。
The boss made the little boy do heavy work. →The little boy was made to do heavy work by the boss. 这个老板让这小男孩干重活。
4. 如果是接双宾语的动词改为被动语态时，直接宾语（物）做主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。
He gave me a book. →A book was given to me by him. 他给了我一本书。
He showed me a ticket. →A ticket was shown to me by him. 他给我展示了一张票。
My father bought me a new bike. →A new bike was bought for me by my father. 我父亲给我买了一辆新自行车。
5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。
We can’t laugh at him. →He can’t be laugh at by us. 我们不能嘲笑他。
He listens to the radio every day. →The radio is listened to by him every day. 他每天都收听广播。
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.这*在照顾这个虚弱的男人。
