It isn’t quite ______that he will be present at the meeting.
A.sureB.certainC.exactD.afraid
B

试题分析: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。
点评:平时学习的时候要把一些经常考查的形容词进行归类总结,特别是同一个形容词有不同搭配,要在语境中进行区别。形容词是高考的重点,一定要加强识记和辨析。做题时一定要结合上下文做题。Sure和certain的不同主要是看主语,这两个形容词都可以和主语是人的搭配,如He is sure to come. =" He" is certain to come。但是如果是it做主语,只能用certain。
