你以后必须开车回家。
shouldn't不应该，needn’t不必，mustn’t禁止，may not可能不。
根据You have to drive home later.可知，你必须开车回家，因此表示你不可以喝酒，故用mustn’t。
故选C。
2．D解析：D【解析】【详解】句意：-我必须今天做完这个工作吗，妈妈？-不，你不必。
你可以明天完成。
mustn’t禁止，不要；can’t不能，不会；shouldn’t不应该；needn’t不必，没有必要。
Must 的一般疑问句，肯定回答用must，否定回答应用needn’t。
故选D。
3．C解析：C【解析】【详解】句意：你已经完成了大部分工作，所以你明天不必这么早就开始工作。
你可以9点来。
本题考查情态动词。
can't不可能，mustn’t禁止，needn’t不必，couldn’t可能不。
根据You have finished most of the work可知，你已经完成了大部分工作，因此明天不必这么早就开始工作，因此用nee dn’t，故选C。
4．A解析：A【解析】【详解】句意：既然你很累，今天就不必完成这项工作了。
A. needn’t不必；B. may not 可能不；C. mustn’t禁止；D. can’t不能。

根据题意，故选A。
5．B解析：B【解析】【详解】句意：——吉姆坐火车来吗？——我不确定，他可能开自己的车。
考查情态动词辨析。
A项，必须，一定，表示肯定推测；B项，也许，表示有可能；C项，需要；D项，应该。
根据回答部分I’m not sure.可知，此处并不确定吉姆是开车来还是乘坐火车来，所以此处是“可能”。
故选B。
【点睛】must意为“必须，应该”，可以表示主观上一定要做什么或者肯定推测。
例如：I must go home to look after my mum. This pair of shoes must be hers. may意为“可以，也许”，可以表示请求或者推测（无法断定）。
例如：May I come in？ It may be hers，but I’m not sure.need意为“需要”，既是情态动词也是行为动词。
例如：You needn’t finish your homework right now. You need to tell him the truth. should意为“应该”，表示责任或者义务。
例如：You should finish practising playing the piano at first.6．B解析：B【解析】【详解】句意：——我能带些牛奶和饼干到阅览室吗？——不行，我们学校规定学生不许在那里食用食物。
