C. dare not tell
D. dares not to tell

A. dares not tellB. dares not telling(答案→)C. dare not tellD. dares not to tell解析：既可以作行为动词又可作情态动词的词除了need以外还有dare.①dare：作情态动词用，一般用于否定句、疑问句及条件状语从句中，一般不用于肯定句中。有时态变化，但没有人称变化。如：He dared not go out alone at night. 他夜晚不敢独自出去。I daren’t ask you, because I thought I was wrong. 我没敢告诉你，担心自己错了。②dare：作行为动词用，在肯定句中常后接带to 的不定式；否定、疑问句中要用do, does, did等助动词，在否定和疑问句中可接带to或不带to的不定式。有人称和时态变化。如：I didn’t dare (to) come. 他不敢来。Does he dare (to) swim across the river? 他敢游过河吗？本题中dare是情态动词的用法。

我也是这个答案
