问题补充:
All the preparations for the task ,and we e ready to start.
A. completed
B. complete
C. had been completed
D. have been completed
答案:
A. completed
B. complete
C. had been completed
(答案→)D. have been completed
解析:
现在完成时表示过去做的事对现在的影响。从and we e ready to start句意可知,一切准备工作已经就续,可以开始工作了。complete是及物动词,与句子的主语是被动关系,所以需要用被动语态表达。
