我想问一下完成时态中 has been ,have heen 和had been 能举例吗,

我想问一下完成时态中 has been ,have heen 和had been 能举例吗,
he has been worked in hospital
表示他过去在医院工作,现在有可能还在医院工作
单数或第三人称时用has
they have been worked in hospital
人称复指,第一二人称时用have
he had been worked in hospital
他过去在医院工作,现在不在了

has been 用于第三人称单数的现在完成时
have been 是第一人称的
had been是过去完成时，在过去的某个时间用的完成时

前两个主要是根据主语来区分，第三人称单数用has 其他用have
have 和 had 的区别是时态上的，过去用had 现在用前两个。
例子
I have been there 10 years age.
The film has been on half an hour.
He said that he had been a English teacher.

我想问一下完成时态中 has been ,have heen 和had been 能举例吗, i hope the Pacific is as blue as it has been in my dreams我希望太平洋的海水如我想像中那样蓝为什么有个 has been 这是什么时态?过去完成时态吗? this hause has been completed since 1991.这里可以用has been completed表示被动的完成时态吗? he has been in the cinema for an hour是什么时态,为什么要用been?完成时态为什么不用go的过去分词,而用been? 问一下关于英语的现在完成时态我想问一下的就是现在完成时态中要用什么时态`可能我讲的比较模糊`说简单点的就是`比如说:I have tried roast duck.后面我想议论roast duck.那么是用过去时态还是英语句子中是不是只要有have been就说明这是个完成时态He has been out (for two days)他不在家（两天）了.这是什么时态,这说明他还持续没在家呢还是回来了.have been后接形容词又是什么时态英语完成时态的构成请问英语完成进行时态的构成为什么不是have,has加现在分词呢?为什么要加been呢? 问一下这句话中为什么可以省略thatthe house i grew up in (that) has been taken down. 在现在完成时态 since 引导的句子中,主句的谓语动词必须用持续动词吗?He has left here since two years ago.He has been away since two years ago.是两个都对,还是有错? sb has been wrong .可以这么说吗.如果可以的话这是什么时态?HAS BEEN+ DONE是被动+分词表完成进行.那加形容词呢? have/has/had加been是什么时态 have/has been+过去分词是什么时态? have/has+been to是什么时态 have/has+been+现在分词是什么时态? have/has+been to是什么时态 have／has been是什么时态?请举例? he has been to beijing.什么时态? now that she is out of a job,mary__going back to school,but she hasnt decided yethas been considering 露茜还没决定就是正在考虑中选项中就是填这个,我想问的是这到底是什么时态.如果是现在完成进行时不是用的
