根据短文内容，完成表格 Lifelong Learning (终身学习) 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 and more common. Lucy, who is forty, teaches physics at a college in Boston. “Next term, I’ll teach some of my classes by using the Internet. This is the way of teaching that I’ve never used before,” says Lucy. “These days, I am taking a class to learn how to teach in this way. If not, I will 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!”
