分析 --我们现在可以离开教室了吗?
--不,你们不可以.你们铃响之前别想 离开.
解答 答案:C.
mustn't,禁止don't have to,不必needn't,不必can't不能.be allowed to do sth 被允许做某事.根据May we leave the classroom now?-No,you.You to leave until the bell rings.可知我们现在可以离开教室了吗?--不,你们不能.你们铃响之前别想 离开.前面以may引导的一般疑问句的否定回答用mustn't表示不可以;后面含有until,所以前面应该有not,构成结构:not…until表示直到…才.故选C.
