首先第一个空就不可能是must,假如用这个的话句意就成了：我必须在这里游泳吗?显然不对.应该用May或者Can 第二个空才该用mustn't,句意为小孩禁止单独在这里游泳.
相信你理解了吧

MUSTN'T 的意思是绝对不行
MUST不符合句意

can't 不能（ 指能力）
mustn't 表示禁止
所以正确的是C

Can I swim here ?我能在这儿游泳吗？can 能：能够
Children mustn't swim alone here.小孩纸禁止在此单独游泳。 must必须 mustn't 禁止，不许
希望能帮到你！

只第一个空就排除ad，第一个的话翻译是“我必须在这里游泳吗”听着你就知道不对了吧，第二个cant理论上可以但是它只表示不能，而mustnt表示禁止，语气更加强烈更加符合对话表达的意思

C
因为Can的语气比Must委婉，因此用Can作问句更好。而回答是表一种坚决的否定用Mustn't更好

您好！Can I ? 是征求别人的意见。mustn't do 是表示禁止，不允许的意思。所以选C .再如：Can I go out now ? No, You must finish your homework first. 望采纳 ！谢谢！
