三、主动语态转换被动语态
step one：将主动句的宾语变为被动句的主语
step two：将谓语动词由主动形式改为被动形式：be+过去分词
step three：将主动句的主语改为被动句中介词by的宾语（by短语有时可以省去）
We plant many trees every year.(主动)
Many trees are planted by us every year.(被动)
My students always share ideas in class.
Ideas ______ always _______ by my students in class.
2. His parents didn’t catch his words at once.
His words _______ _______ by his parents at once.
3. The University will invite many graduates to celebrate its 100th birthday.

shared
weren’t

invited
双宾结构变被动
She gave me a book.
= A book was given to me by her.
= I was given a book by her.
在双宾结构中，直接宾语和间接宾语都可以作为主语，如果把直接宾语变成主语，间接宾语前仍然需要介词to , for.
He passes a cup to me.
They buy a present for Lily.
We showed him a postcard.
My mother made a cake for me.
A cup is passed to me by him.
I am passed a cup by him.
A present is bought for Lily by them.
Lily is bought a present by them.
A postcard was showed to him by us.
He was showed a postcard by us.
A cake was made for me by my mother.
I was made a cake by my mother.
动词短语变被动
We should speak to old men politely.
= Old men should be spoken to politely by us.
不及物动词+介词、副词组成的动词短语在变为被动时，后面的介词或副词不能丢掉。
“主语+谓语+宾语+宾补”
的句式转换
The man painted the door green yesterday.
The door was painted green yesterday.
含有宾语补足语的主动句变为被动句时，可将其宾语变为主语，宾补保留在原处作为主语补足语。
四、注意事项
1. by短语的位置
The kite was made by Jim.
The cup was broken by the boy.
by短语一般放在被动句的谓语动词之后。
四、注意事项
2. by短语的省略。
Computers are widely used nowadays.
Your homework must be finished on time.
These questions should be answered as soon as possible.
在被动句中，当不知道动作的执行者、不想说出动作的执行者或动作的执行者是泛指时，常省略by短语。
