问题补充:
If I more about diamond, I cheated by that man.
A. had known, would not be
B. had known; wouldn’t have been
C. knew; would not have been
D. had known; would never be
答案:
A. had known, would not be
(答案→)B. had known; wouldn’t have been
C. knew; would not have been
D. had known; would never be
解析:这题考查if的非真实条件句,根据句意:如果我知道更多的关于钻石,我就不会被那个人骗了。说明是和过去相反的情况,if条件句用过去完成时,主句用would have done。选B。
