应该选择 C选项
此题可用排除法,首先在意义,句子通顺上上,可排除A和B项；
而对于D项,must是情态动词,虽然must是表示“必须”的意思,但是用于否定式时,mustn't却表示“不要、千万不能、禁止”的意思,而不是表示“不必”,意义上不通顺.
故选C.
Mom,may I watch TV after dinner?No,you ——.You have to finish your homework.
Mom,may I watch TV after dinner?No,you ——.You have to finish your homework.
A needn't B don't have to
C shouldn't D mustn't 我认为是D 关键是may 提问用什么回答的问题
A needn't B don't have to
C shouldn't D mustn't 我认为是D 关键是may 提问用什么回答的问题
