1.掌握各个时态的被动语态的结构与用法；

2.能够熟练运用被动语态解题造句。

一. 含义与构成

1. 被动语态表示句中的主语接受谓语动作，也就是说，主语是谓语动作的承受者。谓语动词用作被动语态的句子叫做被动句。

2. 构成：be + 过去分词(be有时可用become 或get代替), be随着主语的人称、数、时态和语气的不同而变化。

3. 被动语态的各种时态形式有：

一般时态：be + 过去分词

English is spoken in many countries.

Romeo and Juliet was written by Shakespeare.

Many believe that one day the earth will be destroyed if people do not learn to live in peace.

进行时态：be + being + 过去分词

His plan is being carried out successfully.

The new curtains were being hung when the visitors showed up.

The car will be being cleaned by my brother.

完成时态：have + been + 过去分词

I’ve been robbed.

The outcome of the election was announced before all of the votes had been counted.

Everything will have been done by the end of this month.

二. 用法

1. 强调动作的承受者：

Frank was hit by a car.

A new idea has been suggested.

2. 说话者不知道动作的执行者，或者认为没有必要指出：

This bridge was built in 1700.

The house is being repaired.

3. 说话者希望所说的内容显得更加客观，避免就一些自己不太肯定的事表态：

此类通常为表示\"据说\"或\"相信\" 的词组，基本上由believe, consider, declare, expect, feel , report, say, see, suppose, think, understand等组成，如：It is said that…据说；It is reported that… 据报道；It is believed that…大家相信；It is hoped that…大家希望；It is well known that… 众所周知
