Question

— Mum, must I stay there the whole day?

— No, you____________. You____________come back after lunch, if you like.

A. mustn't; can　　　 B. needn't; must　　　 C. needn't; may

Answer 1

C

【解析】選C。考查情態(tài)動(dòng)詞的用法。由must引導(dǎo)的一般疑問句表示否定回答時(shí)需要用needn’t或don’t have to；表示答應(yīng)準(zhǔn)許某人時(shí)情態(tài)動(dòng)詞可以用can或may。故選C。
