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

Answer 1

C

试题分析：句意：我们得等到所有的准备工作都做好了才能开始工作。are being 是现在进行时的被动形式；will be made 是一般将来时的被动形式；have been made是现在完成时的被动形式，用于强调动作产生的影响；had been made是过去完成时的被动形式。本题是主将从现的用法。主句是将来时时，从句用现在时或相当于现在的时态；现在完成时强调过去对现在的影响或动作从过去一直持续到现在。所以选C。
