have been 后接形容词 和 have been doing 的区别 have been + 形容词 和be+形容词 有什么区别? Must have been後面动词,形容词,分别接什麼形式?可以接副词麼?书上有句he must have been stay at home ,stay at home 它和 he must have stayed at home相同么? have since been 和 have been since have been 和have ever been区别! have been premature My negative impression of Nathan may have been premature.He's turning out to be an excellent market analyst.这句话里的have been premature have been后面不是接动词吗,premature是形容词啊 英语句子中是不是只要有have been就说明这是个完成时态He has been out (for two days)他不在家（两天）了.这是什么时态,这说明他还持续没在家呢还是回来了.have been后接形容词又是什么时态 have been 形容词 属于什么语法现象呢? we have been together 里的together是形容词? have been 和 has been的区别 has been和have been区别 弱酸HA加水稀释后A-和HA浓度的比值变化 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 现在完成时后可以跟形容词么?IT HAS BEEN PAID 形容词可以放在名词后吗?there must have been several hundred people present just before the show began.请帮我分析present,这里应该是形容词.我明白为什么放在people后. have/has been 后面可以接形容词吗?它不是接动词过去分词吗?例如：Yao Ming has been successful have been to这里的have 这里have been是延续性动词吗?have been to后能跟for和since引导的时间状语从句吗?I _________the north for a year.这里填have been to 为什么?have been to与have been in如何辨别 have been和have gone的区别
