had meant to do =meant to have done 表示本来打算做但没做成.

had meant to do =meant to have done 表示本来打算做但没做成. had meant to do 表示过去本打算做某事,可以用meant to have done 来替换吗? meant to have done mean to have done=had meant to do时态正确吗.我总觉得前面应该是meant或者后面是ha meant to do和meant to have done有什么区别 meant to do I meant to do meant to do和had meant to do的区别是什么 meant to 有had meant to do 的用法吗意思是什么? I meant to do sth.还是 I meant doing sth. meant to do 为什么省do?
