在被动语态中什么时候动词后要加to,尽量说得简单一些!

网友回答

一般是不及物动词要用的.
主要是看这个动词本身在不是被动的时候是怎么用的,如果要跟介词才能用的,不管是to还是in啊神马其他的,那么转成被动的时候后面都要拖着那个介词的啦~特别是词组神马的要注意!
======以下答案可供参考======
供参考答案1:
1,有些动词后跟不带to的不定式作宾语补足语，但改为被动结构后要加上“to”：
例：He was asked to go to school right now.
He was heard to sing in his room just now.
2.可以接双宾语的一些动词，像give,tell,show：
An apple was given to me.
A ticket was shown to me by him.
供参考答案2:
特殊的：be made to do sth/be seen to do sth(主动式省略to)
一般的：be asked to do sth/be forced to do sth
