答案解析：该题考查连词在宾语从句中的用法。观察题干Mr. Hall understands是主句，其后有that引导的宾语从句，可将该句简化为： ______ maths has always been easy for him， it is not easy for the students.分析简化后的句子可知， maths has always been easy for him与it is not easy for the students之间含有转折关系，其他选项不合题干逻辑。故答案为C.
答案解析：这是一个宾语从句，wants后面缺少宾语，Always give the monkey exactly what he wants是一句谚语，意思是“永远给予他人他确实想要的东西”。故答案为A.
答案解析：由题意可知被猜测的时间是现在，有客观事实根据I saw her in the town a few minutes ago，猜测语气要求最强，所以正确选项是B(can‘t是must的否定式)。
