使用被動(dòng)語(yǔ)態(tài)應注意：

　　1、不及物動(dòng)詞無(wú)被動(dòng)語(yǔ)態(tài)。

　　What will happen in 100 years.

　　The dinosaurs disappeared about 65 million years ago.

　　2、有些動(dòng)詞用主動(dòng)形式表示被動(dòng)意義。

　　This pen writes well.

　　This new book sells well.

　　3、感官動(dòng)詞或使役動(dòng)詞使用省略to的動(dòng)詞不定式，主動(dòng)語(yǔ)態(tài)中不帶to ，但變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)，須加上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.

　　The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.

　　4、如果是接雙賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)時(shí)，直接賓語(yǔ)(物)作主語(yǔ)，那么動(dòng)詞后要用介詞，這個(gè)介詞是由與其搭配的動(dòng)詞決定。

　　He gave me a book.→A book was given to me by him.

　　He showed me a ticket.→A ticket was shown to me by him.

　　My father bought me a new bike. →A new bike was bought for me by my father.

　　5、一些動(dòng)詞短語(yǔ)用于被動(dòng)語(yǔ)態(tài)時(shí)，動(dòng)詞短語(yǔ)應當看作一個(gè)整體，而不能丟掉其中的介詞或副詞。

　　We can't laugh him. →He can't be laugh by us.

　　He listens to the radio every day. →The radio is listened to by him every day.

　　The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
