have been的句式.他表示什么?怎么用? have been是一种什么句式?been是什么? have been句式的回答是用have吗? should have been doing表示什么情况? would have been completed表示什么时态? They will have been married for 20 years by then.这里的been 表示什么 have been 和 have become 在表示“成为”时,它们的用法有什么区别 为什么have done也可表示持续到现在的动作或 状态例如My mother has taught English for twenty years那他和have been doing 表示持续到现在的动作或 状态有什么区别? so...句式,例如so do i.i like reading.i have been to SH.i can swim.mary is reading.i had finished my work.用so...句式表示,像so do i.这样的 we have anxious about you.这句用了have been的什么句式,帮我分析一下这句子.anxious是形容词we have been anxious about you上面打错了 现在完成时的几个问题句式为have++过去分词为什么说他死了要用he has been die而不用he has died?还有,有一个句式是he has already finished his homework,可不可以把already置后? must have been doing与must have been done都表示推测,有什么区别呀? 有关 have been 在本句中的解释How will you account for the fact that you have been late each day this week?本句中的have been的句式是不是现在完成时have done,been在这里的身份是动词be的过去分词?late作什么? have been 跟 have ```分别在那种句式用 已有好多人吃饭了.英语翻译.用there have been 的句式 been的疑问我想问问那有时是那种句式 例如；i have been.那那些也是被动语态吗? I have lived here.与I have been in there.有什么区别?第二句中的been表示什么? 关于“去”的英语 （问的是时态）他去过美国（表示以前去过,现在回来了）他去了美国（在美国呆着,不在说话现场）他马上去美国have been to, have gone to, went to,go to,be going to等等 有什么区别?
