问题补充：

—Would you like to join us in the walk?

—, for I have two important letters to answer.

A. I won’t

B. I’d like to

C. I will

D. I’m afraid not

答案：

A. I won’t

B. I’d like to

C. I will

D. I’m afraid not

解析：选D。考查情景交际。由“for I have two important letters to answer. ”可知“我”不能接受邀请。A项I won’t语气太强, 不符合交际习惯; 而B, C两项都表示同意, 所以此题选D。
