1楼的和2楼的我该听谁的?还有have been和has been后的动词是什么形式来着?再补充下被动语态谢谢

答案和解析
你说的in和on只能说是惯用词组
在办公室 in office
在郊区 on the outskirts
have been 和has been都是现在完成时态,区别只是人称
i have been in the office for all day.
she has been outing for the day.
也就是单数的第三人称就用has been
希望对你有所帮助吧~
been 后面是什么动词要视具体语境来说
如she has been waiting for two hours.这里been只是be的完成时,变成现在时的话就是she is waiting
又如the chair has been broken for several days.这里been broken因为是被动语态,所以后面的动词就是被动形,变成现在时的话就是the chair is broken
不知道是否解释清楚了——||
额——|||
被动语态就是以动作的对象作为主语来进行叙述
比如我弄坏了相机
主动态就是i broke the camera.
被动态就是the camera was broken by me.
