二、主動語態(tài)變被動語態(tài)
步驟：
1. 先找出謂語動詞;
2. 再找出謂語動詞后的賓語;
3. 把賓語用作被動語態(tài)中的主語;
4. 注意人稱、時態(tài)和數(shù)的變化。
1. Bruce writes a letter every week. →A letter is written by Bruce every week. 布魯斯每星期寫一封信。

6. You must lock the door when you leave.→the door must be locked when you leave. 當(dāng)你離開的時候你必須把門鎖上。
三、注意問題
1. 不及物動詞無被動語態(tài)。

2. 有些動詞用主動形式表示被動意義。

This new book sells well. 這本新書賣的很好。
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。
make somebody do something→somebody+ be +made to do something see somebody do something→somebody +be +seen to do something

一個女孩看到我的錢夾掉了當(dāng)她經(jīng)過的時候。
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
這個老板讓這小男孩干重活。
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. 他給了我一本書。
He showed me a ticket.→A ticket was shown to me by him. 他給我展示了一張票。
My father bought me a new bike. →A new bike was bought for me by my father. 我父親給我買了一輛新自行車。
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 at him. →He can?t be laugh at by us. 我們不能嘲笑他。
