    In the past, when students graduated from college and got jobs, only some of them went on with their
study. But today, lifelong learning is becoming more common.
    Lucy, who is forty, teaches physics at a college in Boston. "Next term, I'll teach some classes by using
the Internet. This is the way of teaching that I've never used before," says Lucy. "these days I'm taking a
class to learn how to teach in this way. If not, I'll lose my job." At the same time, Lucy's seventy-year-old
parents, who live in New York, are taking an art history class online."We love this subject," says her father,
"and we learn it to enjoy ourselves. You see we can study with people all over the world. What fun it is to
learn like this!"
