Answer 1

Can I walk across the road now ,Mum?
No you _____ .you have to wait until the light turns green
A.couldn't B.shouldn't C.mustn't D.needn't
选C
选项C.mustn't语气最强，意思是：“禁止、不准”。因为横过马路闯红灯有危险，所以，语气必须强，你说是吗？

Answer 2

选C。记住在英语中mustn't是禁止的意思，通常用于强烈的否定一般都是危险的事情。这道题是考察情态动词的用法。

为什么

追答

由”you have to wait until the right turns green“可知，当时是红灯，红灯时是禁止通行的，所以用mustn't。
