—________ I've booked a table at Michel's restaurant for this evening.

A．What then? 

B．I'm afraid so.

C．How could I? 

D．For sure.

试题答案

C解析：根据“I've booked a table at Michel's restaurant for this evening.”可知并没有忘记对方的生日，故选C项How could I？表示“我怎么能忘呢？”。What then？“那便会怎么样呢？”；I'm afraid so. “我恐怕是这样。”；For sure.“肯定，确定。”A、B、D三项均不符合语境。
