问题补充：

— Mum, many friends of mine are going to Hongenshi Park. Can I go too?

— Wait till you are old enough, dear.

A. Will you?

B. Why not?

C. I hope so.

D. I’m afraid not.

答案：

A. Will you?

B. Why not?

C. I hope so.

(答案→)D. I’m afraid not.

解析：考查情景交际。根据答语“等到你足够大的时候吧，亲爱的。”可知，现在“我”还不能去。Why not?“为什么不？”与答语不符；I hope so.“希望如此”，与答语不符。I’m afraid not.“恐怕你还不能”符合题意。故选D。
