       All around the world, people drink tea. But tea does not mean the same thing to everyone. In different countries, people have very different ideas about drinking tea.        In China, for example, people always

drink tea when they are getting together. They drink it at any time of the day at homes or in the teahouses. They prefer plain tea, with nothing else in it.       

       Tea is also important in Japan. The Japanese have a special(特殊)way of serving tea called tea

ceremony(茶道).It is very old and full of meaning. Everything must be done in a special way in the

ceremony. There is even a special room for it in Japanese homes.       

       Another tea-drinking country is England. In England, the late afternoon is “tea time”. Almost everyone has a cup of tea then. The English usually make tea in a teapot and drink it with milk and sugar. They

also eat cakes, cookies and a few sandwiches at tea time. This is the so-called “Afternoon Tea” in

Britain.       

       In the United States, people drink tea mostly for breakfast of after meals. Americans usually use tea

bags to make their tea. Tea bags are faster and easier than making tea in teapots. In summer, many

Americans drink cold tea-“iced tea”. Sometimes they drink canned iced tea, just as soda.
