问题补充:
Do you think the plan out as soon as possible?
A. should carry
B. ought to be carried
C. ought to have carried
D. ought to have been carried
答案:
A. should carry
(答案→)B. ought to be carried
C. ought to have carried
D. ought to have been carried
解析:句意:你认为这个计划应该尽可能快的被执行吗?根据句意,还没有执行,所以排除完成时态C,D;且the plan 和carry是动宾关系,要用被动结构。所以选B。
