Question

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

Answer 1

B

考查時(shí)態(tài)和語(yǔ)態(tài)。By與完成時(shí)連用，the time our teacher arrives tomorrow使用一般現(xiàn)在時(shí)代替將來(lái)時(shí)，故主句使用將來(lái)完成時(shí)，根據(jù)句意使用被動(dòng)語(yǔ)態(tài)。句意：到明天老師到的時(shí)候，所有的工作都已經(jīng)被完成了，對(duì)此他會(huì)很滿意的。故B正確。
