In the early nineteenth century, people did not use stamps. They had to pay postage（邮费）when they received letters. Sometimes they didn't want to receive a letter at all, but they had to pay money for it. They were unhappy about this. The postage was high at that time, because the post offices had to send many people to get the postage.

Rowland Hill was a school teacher in England. He was the first to think of using stamps in the 1850s. He thought it would be much easier for people to use stamps. They could go to the post office to buy stamps and put them on envelopes（信封）before they sent the letters. The post office could just put seals（印记）on the stamps so that people could not use the stamps again. In this way, the post office did not need postman to get postage. It only needed fewer postmen to send letters.

At a supermarket in County Durham, England, the workers are getting ready for some lessons in sign language (手语). They are excited to meet their teacher — two-year-old Diana Graham. The little girl will teach them how to communicate with deaf(聋的) customers(顾客).
Diana is a wonder child. She began to use sign language to “speak” to her deaf mother before she said her first word. So whenever the phone rings or there’s a knock at the door, her mother can be quickly told by her.
Diana understands the sign language well. Her mother even reads story books to her in sign language. Her grandmother said, “Diana started signing at about five months. She is so clever for her age.”The supermarket officials couldn’t think of a better sign language teacher for their workers. So they asked Diana to give some lessons to the workers. They hoped that her lessons would help the workers communicate better with deaf customers during their shopping.

Some people say, “Extreme(极限的) sports are so dangerous. Why would anyone want to do them?” But the danger is what makes them so excited. Keep reading to find out the most popular ones.

Bungee jumping: People on some South Pacific islands have been bungee jumping for hundreds of years. In 1979, some people bungee jumped off a bridge in England and made the sport popular around the world. Bungee jumping came to China in 1996.
Skateboarding: At first, this sport was called “sidewalk surfing”. Skateboarders often jump high into the air, go down steps or slide(滑行) down rails on their boards. They wear baggy trousers(宽松裤) so they can move more freely.
Skydiving: This is probably the scariest(最惊险的) extreme sport. Skydivers jump out of airplanes about four kilometers up in the sky. They usually free-fall for a while and then open a parachute to slow down for a safe landing.
Snowboarding: This became a winter Olympic sport in 1998. People tie their feet to the board with special shoes. They don’t use any ski sticks. Then, they ride down hills, jump high and do tricks.
