单选题 "Wash every day and you'll die young, my son!" People often said those words; long ago, of course. Napoleon's wife had new clothes every month, instead of a bath. ("It's quicker," She always said). Rich people did not often have a bath. They washed their hands and faces, but not their bodies. Many poor people did not wash at all. A young man once said to a doctor; "Soap and water have never touched my body." (And the doctor answered. "That's true. I know... ")
why didn't people wash in those days long ago?
Well, they did not have water in their house. They carried water from rivers or from holes in the ground ( = wells). Towns people bought it from a water--carrier. Sometimes it was expensive; and soap was always expensive. They drank water, of course; and so they were clean inside. They did not think about the outside! And this is true; they just did not like a bath.
Modern life is different. We use a lot of soap and water. And we are all quite clean. However, a few people use too much soap; and they often get ill. Who are these people?
Many young women work as hairdressers. They wash and then "dress" other women's hair. That is their job, and they like it. Young hairdressers sometimes wash dirty heads on a busy day! Their hands are soapy for seven or eight hours; and that is not a good thing. A young hairdresser's hands are often red and ugly; and she must then go to doctor.

【正确答案】 D

【答案解析】由于当时人们普遍都不洗澡，医生因此不会认为这个年轻人脏，所以A错；B、C也不符合文章的事实，当年青人说：“我身上从未用过水和肥皂。”医生说的确如此，说明医生对青年说的话是毫不怀疑的，所以正确答案为D。
