问题
选择题
---Would you mind if I _______ here?
--- _______ . It’s not allowed.
A．smoke; Yes, please
B．smoked; You’d better not
C．smoke; That’s all right
D．smoked; You are welcome
答案
答案：B
Would you mind if I _______ here?是表委婉的请求，根据It’s not allowed.（吸烟是不允许的。）所以选B，You’d better not，你最好不要吸。If引导的从句用的是虚拟语气，指现在的情况，用过去时smoked。所以选B。
