求助,用There have been开头造一个句子.内容如题,句子不要太复杂 there have been great changes为什么用have been have been there 中文翻译 have been there have been there 还是 have been to there Have you been in there?写成Have you been there? i have always been there i have never been there They have a____ been there There have been 一般疑问句 have you brother been there? 用现在完成时,there have been 和 there has been造句,各造5个 I have been there,have been 是have been in还是have been to的缩写? 请问下过去完成时的用法have you been there?yes ,i have just been there.i had never been there before.请问i have just been there.为什么这句不能用过去完成时而后句又为什么要用过去完成时? have been there =have been in there?have been和have been in 有什么区别呢? have been there与 have gone there的区别 have been there 和 have lived there 有啥区别? 帮我解释一下,这个语法时态,以及用法There have been a number of robberies and muggings.其中,为什么用there have been,不直接用there are there have been many books about historythere have been 这里是不是用了倒装?there have been many books about history是用了什么结构?THERE 后面不能加HAVE?
