— Would you mind if I sing here?

— . Look at the sign. It says “Be Quiet”.

A. Of course not.

B. Better not.

C. Not at all.

D. I don’t mind.

答案：

A. Of course not.

(答案→)B. Better not.

C. Not at all.

D. I don’t mind.

解析：Of course not.当然不了；Better not.最好别；Not at all.一点也不；I don’t mind.我不介意。句意：你介意我在这儿唱歌吗？根据下文，看这个牌子。上面鞋舌“请保持安静”。结合语境可知选B。
