问题补充：
Being afraid of making mistakes,the little boy answer his teacher’s question.
A. does dare
B. doesn’t dare to
C. daren’t
D. not dare to
答案：
A. does dare
(答案→)B. doesn’t dare to
C. daren’t
D. not dare to
解析：句意：由于害怕犯错，那个小男孩不敢回答老师的问题。dare可作实意动词，后接带to的动词不定式。dare的用法如下：dare用作实义动词，此时其后的动词不定式可带to也可不带to，且dare有人称和数以及时态的变化。如：He dares to jump down from the top of the wall. 他敢从那墙头上跳下来。dare用作情态动词，后跟动词原形，主要用于疑问句、否定句和条件句中。如：How dare she do things like that to me? 她怎么敢对我做那种事?故选B。
