问题补充：

It isn’t quite that he will be present at the meeting.

A. sure

B. certain

C. exact

D. afraid

答案：

A. sure

(答案→)B. certain

C. exact

D. afraid

解析：考查形容词：A. sure 确定的，用于Sb be sure that +从句。B. certain确定的，可用于主语是人的时候，还有it作形式主语, that引导主语从句时, 主句中表语只能用certain, 不能用sure，C. exact确切的D. afraid恐怕，句意：他将出席会议不是很确定的。选B。
