for me to climb such a high mountain.

    Every year thousands of young people in England finish school and then take a year off before they start work or go to university. Some young people go to other countries and work as volunteers. Volunteers give their time to help people. For example, they work in schools or hospitals, or they do something helpful for the environment.

    Pauline Jones, 18, lives in Cardiff, Wales. Next year she wants to go to university to study Chinese, but now she's living in Belize. Pauline says, "I'm working with other people here to save the coral reefs (珊瑚礁) in the sea near Belize. The reefs here are beautiful, but if the sea water is very polluted, the coral will die. I'm helping to do research on the coral and the fish that live around the reefs. All over the world, coral reefs are dying. We need to do something about solving the problem before it's too late."

    "I'm staying with a family here and I help do some housework. I don't get any money, but that's OK. I love my work here, and I'm learning a lot about the people of Belize—and myself! When I finish my work, I want to stay here for another three months. I want to travel around Belize and Central America."

    Imagine you receive an e-mail that looks something like this: ARE YOU GOING TO CLASS TODAY? How does1this message make you feel? Why did the sender use2capital (大写的) letters? Was he or she angry,3did the person just4to turn off the "Cap Lock (大写锁定)" on the computer? This e-mail" sounds" like the reader is shouting because using all capital letters in an e-mail is5the way that people shout online.

    Knowing when to and when not to use capital letters is just one6of online etiquette (礼仪).

    Don't do anything online that you wouldn't do in7life. Don't use information that someone else has written, and say it's yours. Do share your knowledge of the Internet with others.
