to have done 目的状语to have done 引出目的状语,这是怎么回事?这语法是属于非谓语动词的用法还是什么?我看了语法书,可是没有说啊, 请问不定式和having done 还有to have done 是不是不能做伴随状语? have done to to be doing和to have done为什么不能作状语 to be done 可不可以做伴随状语 have been done 和 to be done should ought to have done were to have done 造句, be believed to have done were able to have done 条件状语从句题1.If you want ____ you have to get the fund somewhere.A.that the job is done B.the job that is done C.to have done the job D.the job done选什么, seem to do seem to have done have sth to be done/have sth done?为什么要用have anyting to be done? should have done 可以换成 ought to have done嘛? have something done 与have sth.to be done 区别 pretend have done还是pretend to have done? to have been done的用法 我发现语法中很少用这个啊 可以做定语和状语么 to have done,to be done,to have been done,having done在用法上有什么区别?
