使用被動語態(tài)應(yīng)注意：

　　1、不及物動詞無被動語態(tài)。

　　What will happen in 100 years.

　　The dinosaurs disappeared about 65 million years ago.

　　2、有些動詞用主動形式表示被動意義。

　　This pen writes well.

　　This new book sells well.

　　3、感官動詞或使役動詞使用省略to的`動詞不定式，主動語態(tài)中不帶to ，但變?yōu)楸粍诱Z態(tài)時，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、如果是接雙賓語的動詞改為被動語態(tài)時，直接賓語(物)作主語，那么動詞后要用介詞，這個介詞是由與其搭配的動詞決定。

　　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、一些動詞短語用于被動語態(tài)時，動詞短語應(yīng)當(dāng)看作一個整體，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.
