被动语态
Language
被动语态
被动语态的概念:当句子的表达强调动作的承受者时,也就是说主语时动作的承受者
句子使用被动语态
Eg: Some fish are sold
Eg: A piece of grass is tied around the neck
从上面的句子中,你发现了什么,例如:被动语态的结构
被动语态的基本结构:Be+过去分词(当你们在做题时发现这一个句子使用的是被动语态,就必须具备这两个条件
被动语态同其它语态一样,都有各种时态
Let's go
各个时态的被动语态的结构
一般现在时:am/is/are+done
一般过去时:was/were+done
一般将来时:will/shall+be(原形)+done
Am/is/are going to be +done
现在进行时:am/is/are being +done
现在完成时:has/have been +done
情态动词的被动态:情态动词+be(原形)+done
我们还可以加上by在被动语态的句子中,告诉我们谁或谁做某事
Eg: English is spoken by us
Eg: This maths problem is worked out by Jim
主动语态变成被动语态的方法:
1、把主动语态的宾语作为被动语态的主语
2、把主动语态的谓语改为被动形式
3、把主动语态的主语做by的宾语
4、把主动语态句子其余部分补充到被动语态的句子中
注意:不及物动词没有被动语态
如:happen 、 take place 、break out
主动语态句子主语谓语(主动形式) 宾语其余部分
被动语态句子主语谓语(被动形式) by宾语其余部分
Eg: we must keep this in mind this must be kept in mind
Eg: JIm is mending my bike now My bike is being mended by Jim now
当感官动词或者是使役动词出现在被动语态中,不能省to不定式,必须将to找回来
感官动词 hear,see,feel,taste,sound (橙色的感官动词, 没有被动语态,hear,see,就有)
{
被动语态的使用判断: 1、主语为动作的承受者时 2、句子中动作的执行者为by的宾语时
