It has to be admitted that...这是什么语法?为啥用被动语态啊? Nowadays it has to be admitted that more and more college gr Nowadays it has to be admitted that more and more people wil 这是关于被动语态的,就是不明白这句改成被动语态have to为什么变成has to啊 He has been to Dalian 的被动语态是什么? we aren’t allowed to touch it.这句话为什么用被动语态啊? be admitted into/to的区别是什么? It must be admitted that this condition -----better than it It's a pity that theconcert has been cancelled.是被动语态吗? 用allege to be造个被动语态的句子 be going to do 的被动语态 to be是被动语态吗?
