将下列句子改为被动语态
We planted trees last week.
主动语态变被动语态解题步骤
1. 找宾语 ----即动作的承受者
2. 判断宾语的单复数 ----即be动词的单复数.
3.把谓语改成was/were+V.过去分词
5. 修改原句的主语 ----即by+ 主语/ 宾语.
宾变主,主变宾,前加by
动变被,看清be, 结构分别be+ pp
Tree was planted by us.
4. 判断新主语的单复数:确定be动词的单复数
He washed his car yesterday.
His car was washed (by him)yesterday.
Did you clean up your room last night
Was your room cleaned up last night
He saved the lives of the children.

Practice I
主动语态变为被动语态的注意事项：
几种特殊的被动语态
① “不及物动词 + 介词/ 副词”(介词/副词不与动词拆开或漏掉)
e.g. The man cut down the tree. →
② 在主动句中, 使役动词(如make等)和感官动词 (如see, watch, notice, hear等)后面常接不带to的动词不定式作宾语补足语; 但在被动句中，这些词后面的动词不定式都带to。
e.g. We heard Mary sing in the next room. →
感官动词
一感二听三让四看
主动句中to 离开，被动句中to回来
We often heard Kate sing in the room.
The tree was cut down by the man.
Mary was heard to sing in the next room.
Kate was often heard to sing in the
room (by us).
③ 含有双宾语的主动句变被动句时，如果直接宾语(物)作主语，则需在间接宾语(人)前加介词to或for。
e.g. Peter gave me a pen.
间接宾语
直接宾语
a. I was given a pen by Peter.
④ 有些动词常用其主动形式表示被动意义，如sell, wash, write等和表示感觉、知觉的系动词feel, sound, taste, smell等。
e.g. This kind of dress sells well.
The fish tastes very delicious.
含有双宾语的主动句变为被动语态时，通
把指 “人”间接宾语变为主语，而指“物的直接宾语则不变
如果要把指“物”的直接宾语变为主语，则在间接宾语前加to或for。
b. A pen was given to me by Peter.
Some food was brought to him (by me).
I brought him some food.
When was the zipper invented It was invented in 1893.
Who was it invented by It was invented by Whitcomb Judson.
When was tea brought to Korea It was brought to Korea during the 6th and 7th centuries.
