听力原文：W: When did you become interested in collecting stamps？
M: Oh, when I was about ten years old. It's an exciting hobby. You know, the first postage stamps were issued in Britain in 1840.
W: Really？ I didn't know that. I did know that the charge for mail delivery before postage stamps was paid by either the sender or the receiver. How much was the usual charge？
M: Oh, about ten cents for a short distance. But post offices were losing money with that system. Rowland hill, an Englishman, suggested using postage stamps. Here's a picture of the first two stamps issued.
W: They both bear a picture of Queen Victoria.
