英语语法：it's been a while 已经有一段时间了 'S是否是 has 这句子成分是什么 哪个是动词
een可以是be,也可以是go的过去分词.
It's 可以是It is ; It was ; It has ；a while表示一段时间.
1、It is been a while.= It is gone a while.被动【一般现在】一会
2、It was been a while.= It was gone a while.被动【一般过去】一会
3、It has been a while.= It has gone a while.主动【现在完成】一会
1=3.如果把虚词 it 换成实词,就一目了然了哈,比如换成cat,动词也就清楚了啥.
再问： 请分析下句子成分 哪个主语 哪个谓语 哪个宾语什么的
再答： 老兄啊，典型的“be+分词”式系表结构啥：主语为虚词it，is, was, has作状态系动词，分词been就是状态了哈。
再问： a while是表语的意思吗 这里a white是什么词性？ 考虑到后面还要带个从句 又是如何分析？
再答： 补充成分。 前面是缩写，后面带的从句时态就比较自由了，此时的分析应以从句的谓语动词为准。
it's been a while since I've been here翻译是 我有一段时间没来了 还是 我来了有一 It's been a while It's been a ride这是一个现在完成时句型吗 it's是it has的缩写吗 It'S Been A While 歌词 It's getting dark.中的It's 是否是It is ?句中哪个是系动词? It`s been a pleasure to talk to you.中 It`s 是It has 还是It is? It's a pity that theconcert has been cancelled.是被动语态吗? 英语翻译有个老同学去美国很多年了,近日收到她一封信 it has been a long while!How's eve It's been a while since I left here It has been的缩写 It’s been It is Tom 的缩写It’s Tom 这两者缩写后的发音是一样的 It's has been accepted It has been 3 years since he smoked.为什么这句话的意思是他不吸烟已经三年了?
