考查時(shí)態(tài)。By+將來(lái)的時(shí)間，主句用將來(lái)完成時(shí)；by+過(guò)去的時(shí)間，主句用過(guò)去完成時(shí)。By引導(dǎo)的從句用一般現(xiàn)在時(shí)代替將來(lái)時(shí)。work和finish主句是動(dòng)賓關(guān)系，故用被動(dòng)語(yǔ)態(tài)；再根據(jù)tomorrow可知，主句用將來(lái)完成時(shí)；綜合用將來(lái)完成時(shí)的被動(dòng)語(yǔ)態(tài)。句意“到明天她到達(dá)的時(shí)候，工作已經(jīng)被做完了�！惫蔬xB。
