How to use modal verbs in the passive voice? 语态 (Voice) 是动词的一种形式,它表示句子的主语和谓语动词之间的关系。语态通常分为主动语态和被动语态。
被动语态 (Passive Voice) 表示句子的主语是动作的承受者。其句子的谓语动词是:be + V-ed形式。被动语态指出句中的主谓宾语。We kept food in the fridge.We must close the windows and the door.S V.O.SV.O.

sb. be seen/heard/made to do sth.They saw the boy fall from the tree.The boy was seen to fall from the tree. 相当于及物动词的短语动词也可以有
被动语态。 如: look after, give up,
take care of, pay attention to, make
use of, put off, wake up, put out等。The children are taken good care of.The big fire has been put out.孩子们得到了很好的照顾。大火已经扑灭了。4. 短语动词结构。特别注意1. 在被动语态中,有时get可用来代替be,如get changed, get hurt和get dressed等。Please wait a while. I’ll just go and get changed.2. 表示状态的动词不能用被动语态。I have many science books.
VR films belong to the latest wave of new technology.3. 有些动词可用主动语态形式来表示
被动意义,如:open, write, read,
sell, wash, measure等。Your article reads well.This type of car sells well in China.This hall measures 100 metres long and 60 metres wide.4. 在一些固定句型中常用被动语态。 如:1) It+动词的被动语态形式+that引导的从句

It is reported that …
It is believed that …
2) 主语+动词的被动语态形式+动词不定式
