have been coming 后加了for weeks 是错了?I've been coming up here night after night for weeks coming是不可以加for 表示段时间的 因为他是瞬间动词,书上写错了?我知道 但是coming是瞬间动词 可以表示将来,但是不 have been后加动词原型还是过去式谢谢了, 现在完成时have后什么时候后面加been? have been 后面加什么,have呢have been后什么时候加过去分词,什么时候加ing 我已经完成作业了,I have （完成） my homework ,完成是不是要用过去式 Have/has been 后一定要加doing sth.吗? have been keeping doing 为什么错了是因为have been后面不能加状态么 here coming Jenny’s teacher?here后加coming Have you been?A place I've never been这句话中been后要不要加东西?为什么？ have been on加什么 There have been great changes in our city since 1978.have been 后加的不是动词过去分词么这个句子的中have been 的用法 have been they have been doctors中been后直接加名词doctors.那为什么have been to China中必须加to等介词才能加名词China? 请问HAS BEEN和 HAVE BEEN HAD BEEN的用法以及分别加DONE后的用法请问HAD BEEN 单复数用法有区别吗 have been to 与have been 有什么不同 是否have been to 加名词 have been 加副词? have/has been后接地点名词时,中间为什么要加to been 的用法我不太懂为什么有的时候have后直接加过去分词有的时候就得加been在加过去分词 啊?
