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
