含有allow的被动语态句子怎么改成主动语态!
我只知道主谓宾结构怎么在主动与被动语态的转换.
但这种句子怎么变成主动语态?
You are not allowed to use a camera in here.
还有很多类似的,如 Smoking is not allowed.
以上句子怎么改成主动语态啊?

Answer 1

首先要知道一个主动语态的句子如何变成被动语态.能变成被动语态的句子必须是主谓宾都有.把主动语态里的宾语变为被动语态的主语 然后+be (一般现在时用am/is/are 过去时用was /were)+ done + by + 主动语态句子里的主语的宾格.比如：she speaks English.---- English is spoken( by her).多做些就熟悉了.然后再试着往主动语态变.
You are not allowed to use a camera in here.-------(自己加一个适合的主语根据上下文)(The museusm doesn't allow you to use a camera in here.)
还有很多类似的,如 Smoking is not allowed.
The host doesn't allow smoking.
