选择题
By the time our teacher arrives tomorrow, all the work _____,with which he will be content.
A．is accomplished
B．will have been accomplished
C．will be accomplished
D．has been accomplished
答案
答案：B
考查时态和语态。By与完成时连用，the time our teacher arrives tomorrow使用一般现在时代替将来时，故主句使用将来完成时，根据句意使用被动语态。句意：到明天老师到的时候，所有的工作都已经被完成了，对此他会很满意的。故B正确。
