Could you……？表示委婉的请求，不表过去；表示能够，用情态动词can。
故选C。
2．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。
根据上文Since you are very tired,可知，情态动词needn’t表示不需要，后面直接加动词原形。
根据题意，故选A。
3．A解析：A【解析】【详解】句意：——Tom，我们8点将会去购物，对么？——是的，但是我可能会晚一点，所以不要等我。
考查情态动词词义辨析。
A. may可能；B. should应该；C. mustn’t禁止。
根据句意可知是可能会晚到。
故选A。
4．B解析：B【解析】【详解】句意：——难道弗莱克不喜欢待在家里照顾他的小妹妹吗？——是的，但是他不得不这么做因为他的父母都去工作了。
考查一般疑问句。
has to不得不；doesn’t have to不必。
根据后面的both of his parents work 可知，弗兰克不得不在家照顾妹妹。
而且but表示转折，跟前面表述的是相反的，问句是一个否定式的一般疑问句，回答“No+否定句”，no翻译成“是的”。
故选B。
5．C解析：C【解析】【详解】句意：——你能告诉我一些在加拿大或者在美国的生活吗？——抱歉，我不知道，我来自澳大利亚。
could可以是can的过去式，但是在位于句首表示请求对方做某事的时候，表示礼貌而非过去时态。
can表示能力，表示能够做某事。
在空格一中，表示礼貌请求对方做某事，用could表示委婉语气；空格二中can’t表示回答者做不到，因为回答者来自澳大利亚而非加拿大或者美国。
故选C。
6．A解析：A【解析】【详解】句意：牛奶味道不好。
你最好把它扔掉。
考查had better和人称代词宾格。
throw away意为“扔掉”，根据所给空前面的had better后面接动词原形，排除B和D，由milk是不可数名词，所以用it来代指，排除C，故选A。
7．D解析：D【解析】【分析】【详解】句意：——看！史密斯太太正站在教学楼的前面。
——不可能是他。
她去埃及度假了。
考查情态动词表示推测。
must be一定是；mustn’t be禁止是；can be可能是；can’t be不可能是。
根据She has gone to Egypt for her holiday.可知她去了埃及，不可能站在教学楼前，故选D。
8．B解析：B【解析】【分析】【详解】句意：——杨小姐，我能从图书馆借这些书吗？——对不起，你不能。
这些书仅供英语俱乐部的会员借阅。
考查情态动词的用法。
can“能，会”，情态动词；could是can的过去式。
表示请求允许（即请求别人允许自己做某事）时，既可用 can也可用could，但这里的 could 并不表示过去，而是表示现在，只是比can的语气更委婉。
若表示给予允许（即自己允许别人做某事），一般只用can/can’t。
综上所述，故选B。
9．B解析：B【解析】【分析】【详解】句意：——今天下午你可以和我一起去闲逛吗？——对不起，我不能。
我必须为清洁日定计划。
考查情景交际。
Sorry, I couldn’t对不起，我不能。
