不，不需要。你可以在晚饭后做。考查情态动词。neednt不需要；mustnt禁止；shouldnt不应该；cant不能。根据英语语法，对于must开头一般疑问句，若要作否定回答，可用neednt，不用mustnt。故选A。9C解析：C【详解】句意：你为什么不早点告诉我？ 我为什么应该告诉你？我想要保守我自己的秘密。

careful.我们还是要非常小心。正确答案为：D【点睛】would，could，must，might，may，can都可以表示“可能性”：按照可能性的大小可以排序为might、may、could 、can、should、would、must。也就是说，might表示最小的可能性，must则表示达到最大的可能性。如：He might be at home. 他或许在家（但是可能性不大）。He may be at home. 他或许在家（稍有那么一点儿可能）。He must be at home. 他一定在家。此外，它们还表示各自独特的意思：may / might 表示有应承，即“可以”；can / could 表示有能力，即“能够”；should 表示有义务，即“应该”；would 表示有愿望，即“愿意”；must 表示有必要，即“必须”。13C解析：C【详解】句意：在我小的时候，我的父亲会带我去爬山，那离我们家不远。考查情态动词。may可能；must一定；would将要；should应该。本题考查情态动词的用法，由When I was young
