（一般现在时态）
什么是被动语态
被动语态(Passive Voice)表示句子的主语是动作的接受者或受影响者。
被动语态的基本动词形式是be+V-ed。通过改变be的时态，可以构成不同时态的被动语态。
什么时候用被动语态
当我们不知道谁是动作的执行者，或者没有必要说明谁是动作的执行者，只需强调动作的承受者时。
怎样变成被动语态
◆ 主动语态变被动语态的方法
① 主动语态的宾语变成被动语态的主语。
② 主动语态的谓语动词变成“am / is /
are+及物V-ed”形式。
③ 主动语态的主语变成by引导的介词
短语放在主谓结构后面，有时可以省略。
时态变化
被动语态有人称和时态的变化，都在be动词上做变化。
一般现在时： is/ am/ are + done
e.g. This shop is owned by my sister.
I am not allowed to go out alone.
Are you required to go to school on time
Umbrellas are used for keeping off the rain.
伞是用来遮雨的。
一般现在时被动语态的基本结构：
主语 + am/is/are + 及物V-ed +by +宾语（逻辑主语）　
Tea plants are grown on the sides of mountains.
The model plane is made of used wood and glass.
Chopsticks are usually made of wood.
一般现在时态的被动语态的几种句型
1.肯定句: 主语 + am/is/are + V-ed + (by…)
The news is published by the government.
2.否定句: 主语 + am/ is/are + not + V-ed + (by…)
3.一般疑问句: Am/ Is/Are + 主语 + V-ed + (by…)
The news isn’t published by the government.
Is the news published by the government
特殊疑问句:
疑问词 + am/is/are + 主语 + V-ed + (by…)
When is the news published by the government
被动语态的特殊情况
1） 不及物动词不用于被动语态
如： arrive, go ,come, die, happen, take place， appear, disappear等
2）hear/see/ notice/ make/ let/ have sb. do 等变为被动语态后，要将省略掉的to 加上。
The teacher made him clean the classroom.
He was made to clean the classroom by the teacher.
一般过去时 was/ were + done
e.g. The window was broken by a little boy yesterday.
Was telephone invented by Bell
The trees were not cut down by local people.
拓展
现在完成时：have/ has been + done
e.g. My car has been fixed a few times.
Have the desks been moved to the classroom
The gifts haven’t been opened yet.
拓展
4) 含有情态动词的被动语态
情态动词+ be + done
e.g. The desk should be cleaned every day.
