we never dared to ask him,did we和the little boy dare not go

dare情态动词，可以直接加not或作为构成一般疑问句（也有过去式dared) 如 I dare not go out at night. Dare you go out at night? 不用于肯定句。 但也有 I dare say我敢说。 行为动词： 跟行为动词do用法一样的。 肯定： He dares to go out at night. 否定： He doesn't dare to go out at night. 疑问： Does he dare to go out at night? 跟need的用法类似的。
