     When we ask students what they want to be, they often talk about unusual jobs, things like teachers

and doctors. But if you think about it, many people don't plan to do their jobs. They just start doing

them by accident. We have talked to two people with unusual jobs.

     Emily is a dentist (牙医) but she doesn't work with people. She works with horses. After university

she took care of animal's health for several years, but she noticed that there were few people who could

help horses' teeth. She decided to go to college and study again. Then she had to buy special tools, but

she is never out of work. She's always very busy taking care of horses' teeth. "I couldn't be a dentist for

people now," Emily said, "because I really enjoy working with horses."

     As soon as David could read, he read books about robots, but the robots he built today don't look

like the strange robot people in his books. He builds robots for industry. Early one morning he made up

his mind to study maths, science and computers so that he could break into the world of robot engineering. "Some of the maths is very difficult," says David, "but you must study maths to be an engineer." Fortunately he got top marks in all his math exams.
