Your sister must be helping the little girl with her homework, _______ ?

A．needn’t she

B．mustn’t she

C．isn’t she

D．must she

答案

解析

试题分析：句意为：你的姐姐一定是正在帮助那个小女孩儿做功课，不是吗?句中的must不是必须的意思，而是表示对现在正在发生的事情的肯定推测，表示推测的句子的反意疑问句变化时应还原成不推测的句子，所以这个句子应还原成：Your sister is helping the little girl with her homework,______? 故应填isn’t she.答案为C。
