问题
选择题
By the time our teacher arrives tomorrow,all the work _____,with which he will be satisfied.
A．is accomplished
B．will have been accomplished
C．will be accomplished
D．has been accompished
答案
答案：B
题目分析：by the time + 将来时间，主句用将来完成时，故选B。句意：到我们老师明天到达为止，所有的工作都将会被完成，他会很满意的。
点评：本题不难，将来完成时用来表示在将来某一时间以前已经完成或一直持续的动作，经常与before+将来时间或by+将来时间连用，也可与before或by the time引导的现在时的从句连用。
