have/has/had+p.p 完成式 (至某個時間點止的行為)
have/has/had been+V-ing 完成進行式(至今仍"持續"的行為)
Two days have passed before he could get up and walk around.
=Before he could get up, two days have passed.
=Two days have passed, he could get up and walk. 在他可以起身走動前,已經過兩天。(直到兩天前他還不能起身走動)
經過兩天先發生,起身走動後發生,"have/has/had been+V-ing"用法不通、語意也不合
