Speaker A: Hello,Jane. How lucky to run into you! Can you and Tom come to dinner tomor-row evening?

Speaker B: _________. I don't think we're going out.

A. I suppose I can't

B. I'm afraid not

C. It's my pleasure

D. I think so

D 【解析】說(shuō)話者A偶遇說(shuō)話者B—Jane和Tom，并邀請(qǐng)二人明晚一起共進(jìn)晚餐。說(shuō)話者B的答語(yǔ)后半部分說(shuō)他們明天晚上不會(huì)外出，意即同意赴約。A項(xiàng)、B項(xiàng)均表示不同意，C項(xiàng)是針對(duì)致謝用的答語(yǔ)，表示“不用謝”，只有D項(xiàng)是表示同意的答語(yǔ)。因此。D項(xiàng)正確。
