have been是一种什么句式?been是什么?

have been是一种什么句式?been是什么? have been句式的回答是用have吗? have been的句式.他表示什么?怎么用? 现在完成时什么时候加been,什么情况加一种是直接have加过去分词，另一种是have been+过去分词。分不清楚什么时候用have b+ 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 You must have been driving at seven miles an hour句中的must have been driving是一种什么语法及此句的汉语意思 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? 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? have been 跟 have ```分别在那种句式用 Have you ever been to Hangzhou,_____is famous for the West Lake?10.Have you ever bee to Hangzhou,什么是限制性定语从句?什么是非限制性定语从句?这两项有什么区别?请举例说明? 关于been的一个疑惑The house has been built 10 years ago by him . 这房子是他10年前建造的（实际上是被他建造的）. I have been very busy the last few days 这里的been 是 be动词 的过去分词形式, 和上面的 have bee Have been 什么意思? bee,什么意思? a picture has been painted是什么句子?如题 是被动语态的什么句式 He has been doing这个句式是?代表什么?如何使用?请朋友解答. bee是什么的单词 It is the second time that I have been to Bingjing.这是强调句式还是定语从句?不是强调句式，是什么句式？从语法角度能说明吗？ have been to sp和 have been sp和 have been sth?特别是have been sp是表示曾经到过什么地方,还是表示一种状态?请知道的人告诉一下!
