如何學好英語語法：使用被動語態應注意的幾個問題 ，希望對大家的學習有所幫助。
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
　　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.
　　5. 一些動詞短語用于被動語態時，動詞短語應當看作一個整體，而不能丟掉其中的介詞或副詞。
　　We can't laugh at him. →He can't be laughed at by us.
