it is no use telling him not to do worried 这一句中的真正主语是什么?是tel It is no use telling him not to worry.为什么tell不加不定式啊 It is diffcult for him to do it 真正的主语是TO DO IT那谓语是什么吖 It is no use telling him about it.可以改为It is no use to tell h 把这句话进行剖析“It's no use telling him not to worry.” It is no use telling him about it .It is no use (tell) _____________ him what to do it is no use telling him about it .请问about it在句中做何成份? It`s no use you telling me not to worry.为什么不能用tell? it is no use to do 与it is no use doing 有什么区别? it is no use doing sth.与it is no use to do sth.的区别 It is no use doing sth与It is no use to do sth的区别.
