Mary: We're having a few people over for a dinner party Friday. We'd love to have you.

Tom: ______

A. Oh, I'd love to. But I’m afraid.

B. Oh, really! What time should I come?

C. No, I have to prepare for the exam.

D. Yes, though I have to take the exam.

［答案］B

【精析】Mary邀請Tom出席星期五的宴會。選項A（噢，我愿意，但我恐怕）表達不完全；選項B（噢，真的嗎？那我幾點鐘來？）符合交際語境；選項C（不來，我要準備考試）、選項D（好，雖然我要參加考試）表達不夠委婉，過于直接，而且一般不用yes跟no應答別人的陳述句。
