题目内容
We won’t start the work until all the preparations __________.
A. are being made B. will be made
C. have been made D. had been made
C
【解析】
试题分析:句意:直到所有的准备工作已完成,我们才会开始工作。A. are being made现在进行时的被动;B. will be made一般将来时的被动;C. have been made现在完成时的被动;D. had been made过去完成时的被动;这里主句是一般将来时,until从句应该用一般现在时或者现在完成时,符合“主将从先”的语法习惯。故选C。
考点:考查动词时态。
