语态讲解 | 被动语态的使用的几个注意点
英语中的语态体系浩如烟海，里面学问很大，掌握语态的用法对学习英语有很大的意义。今天，小编为同学们带来了相当丰富的与被动语态的用法相关的语法，一起来看看吧！
- 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。
- 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。
- 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。
- 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，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。
- 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。
