By the time our teacher arrives tomorrow,all the work _____,with which he will be satisfied.
A．is accomplishedB．will have been accomplished
C．will be accomplishedD．has been accompished
B

試題分析：by the time + 將來時間，主句用將來完成時，故選B。句意：到我們老師明天到達為止，所有的工作都將會被完成，他會很滿意的。
點評：本題不難，將來完成時用來表示在將來某一時間以前已經(jīng)完成或一直持續(xù)的動作，經(jīng)常與before+將來時間或by+將來時間連用，也可與before或by the time引導的現(xiàn)在時的從句連用。
