高中英語必修三語法知識
使用被動語態應注意的幾個問題：
1. 不及物動詞無被動語態。
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，主動語態中不帶to ，但變為被動語態時，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時，直接賓語(物)作主語，那麼動詞後要用介詞，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.
