has been和had been 有什么区别

Question

如题所述

Answer 1

区别：

一、

has been是现在完成时.

had been是过去完成时.

（1）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 

（2）单数或第三人称时用has 

they have been worked in hospital 

（3）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

二、

have been 和 has been 只是根据前面主语的人称而定。都是一般现在完成时

简单来说如果前面是I,you,we以及复数形式的主语则是have been

第3人称单数如he,she,it,则是用has been

有been的话表示被动语态

had been则是过去的过去，是过去完成时，和上面一样有been的话表示被动语态

如果都加done的话，都是表示已经做完某个事情，只是时态不同

had been 单复数用法没有区别 第一第三人称都是用had
