(首字母不大写了）
one day andrew's son is ill, so andrew takes him to see a doctor. the doctor 's sister is just henry' wife. we know andrew isn't a driver. and the farmer isn't married.the farmer has many good hens, so he often sells eggs. sam buy eggs from the farmer every week. the teacher sees henry every morning because they live in the neighborhood. what do they do? now piease tell me.
(不是要你翻译 是叫你推理出各自的职业）
Andrew Smith is a teacher ，Sam Miller isa doctor,Henry Hall is a driver,Frank Green is a farmer
Henry Hall 不是农民和老师，你可以推出来的，the doctor 's sister is just henry' wife，伦理上他不能娶姐姐为妻子，所以只能是司机。
Andrew Smith不是医生和司机，你可以得出的，the farmer isn't married，而Andrew Smith有儿子已结婚，所以他不是农民，只能是老师。
Sam Miller buy eggs from the farmer，他不是农民，只有老师一职了
Frank Green只能是农民了

四种职业：医生，教师，司机，农民
已知andrew不是医生，也不是司机，也不是农民（他有孩子）Henry不是农民（因为农民没结婚）也不是教师，也不是医生，sam不是农民。
因此首先推出Henry是司机，andrew是教师，那么sam就是医生，Frank就是农民
