music show will be held in the school hall at . on Tuesday, 4 May.

5月4日星期二下午4点，将在学校大厅举行音乐表演。

说明：句1是一般现在时的被动语态，句2是一般过去时的被动语态，句3是一般将来时的被动语态。

英语的语态有主动和被动两种：主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。

1.基本构成

be+过去分词

Football is played all over the world. 足球风靡世界。

Is it made of bamboo? 它是用竹子做的吗？

2.基本变法

We Visited that factory last summer →主动语态

主语谓语宾语其余部分

That factory was visited by us last summer →被动语态

主语谓语宾语其余部分

宾语提前做主语，主语变为介词by的宾语，谓语变为be+过去分词，时态根据主动语态来确定。3.省去by的几个条件

(1)不知道、没必要或不想说出动作的执行者。

Rice is grown well there.

(2)强调说明动作的承受者

I was sent to teach them English.

(3)汉语中有“据说、大家说”等

It is said that one day he climbed to the top of a house.

4.各种时态的被动语态

(1)一般现在时的被动语态

am/is/are+过去分词

I am often given gifts by Tom.

The things on show are all made in China.

Is the room cleaned everyday?

(2)一般过去时的被动语态

was/were+过去分词

Jim was asked to go there.

The visitors were stopped from leaving the top of the mountain by the heavy snow.

(3)一般将来时的被动语态

will be+过去分词或者am/is/are+过去分词

Lots of trees will be planted on the hill next year.

The children won’t be allowed to go out at night.

Is the bridge going to be built by the workers next year?

5.特殊情况：复合宾语的被动语态

感官动词和使役动词在主动句中，其后的动词不定式不带to，但变被动句时必须加上to.主动：The boss made her work for 10 hours a day.

被动：she was made to work for 10 hours a day.
