The boy is ________ see the teacher because he ________ a mistake.

A. afraid of; has

B. afraid to; has made

C. afraid to; make

D. afraid of; made

【答案】

B

【解析】

句意：这个男孩害怕见到老师，因为他犯了错误。Be afraid to do sth害怕做某事，Be afraid of 后跟动词ing形式；后半句表示过去曾经做过的事情，强调对现在造成的影响和结果，使用现在完成时态（结构：have/has+动词的过去分词） 所以选B。
