have been 用法如一个句子:He asked me whether the work has been finished.and I said it has been.后面那一句子.我说已经完成了.是不是就用has been就行了? 一个句子中有for用现在完成时还是过去完成时?就是一些关于过去完成时或现在完成时的用法.有since一般是过去完成时,have/has+been+过去分词但是在一个句子中有for,例如：he （ ）（ ）a（ ）（ 求助,用There have been开头造一个句子.内容如题,句子不要太复杂 have been 的用法? have been的用法现在完成时的状态用法我知道,但有时候对于这个been的用法很不解,有些句子中有been 可是有些句子中木有been.不知道是做什么成份,有什么含义.比如以下的两个句子,He has been busy s 讲一下have been的用法,如题 have been done；have been doing;have been n(如friends);have been adj(如asleep)辨析,尤其been的解释have been done；have been doing;have been n(如friends);have been adj(如asleep)辨析,尤其been用法；完成时用法’被动语态用法 have been to and have gone to用法区别在那里?如果现在完成时一个句子里面有两个动词都需要加上它的过去时吗？ 英语语法：错综时间的虚拟语气的用法虚拟语气中，句子的主句和从句的动作发生的时间不同时，如：If he ____ my advise,he _____ much better now.A.took,would be B.had taken,would be c.had taken,would have been D.ta have been+adj的用法 have ever been 的用法? have been用法知多少 have been on的用法 have been用法知多少 It turned out that he had never been there.在这个句子中,it是什么用法,是形式主语么?如题. the man has been dead for many years.为什么不用用died如题,为什么dead不能用died,像一个句子里：they have been married for two years.这里为什么又用married这样的格式啊?还有一个，he has been playing golf for ten year you have been so gracious.解释这句话的用法.很少见到称赞的句子用have been的 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
