Tea has a long history with more than two thousand years. Its hometown is certainly China.

At first tea was considered as a kind of good thing that could make people awake so that they could study comfortably. Many knowledgeable people thought it was helpful for their study, because their minds could keep awake after drinking too much tea. During Tang Dynasty, tea was sent to European countries first through the Silk Road. It was tea that made Chinese culture spread over in western countries. The first book about tea was The Classic of Tea by Lu Yu in Tang Dynasty. In the book, he described all the tea cultures.

However, the tea culture changed into a kind of new form. Many people could find something bad in it in Song Dynasty. Many people spent much time on it instead of thinking about the safety of their country. Between the end of Yuan Dynasty and the beginning of Qing Dynasty, plenty of people paid more attention to tea. People thought of it as the symbol of the spirit.

Nowadays, tea has become the most gentle and comfortable drink in France. It also becomes a helpful drink that is good for people's skin and health in England. Lots of Chinese look on tea as one of the most popular presents that they give others on important festivals.

When you want to go shopping, decide how much money you can spend on new clothes. Think about the kind of clothes you really need. Then look for those clothes on sale.

There are labels inside all new clothes. The labels tell you how to take care of your clothes.

The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash it in cold water. The label on a coat may say“dry－clean only”. Washing may ruin this coat.

If you do as the directions say on the label, you can keep your clothes looking their best. Many clothes today must be dry－cleaned. Dry－cleaning is expensive. When buying new clothes, check to see if they will need to be dry－cleaned. You will save money if you buy clothes that can be washed.

You can save money if you buy clothes that are well made. Well－made clothes last longer. They look good even after they have been washed many times. Clothes that cost more money are not always better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes.

People drink a lot of tea in England. Every afternoon, people drink tea. It’s “tea time”. English people like to drink their tea with milk in it.

Many people drink black tea in the US. In the South, people like to drink sweet tea. Sweet tea is cold black tea with sugar in it.

Most tea comes from China. Some tea comes from India or Sri Lanka. Kenya, Japan and Indonesia also grow tea.

In today's world of mobile phones, MP3 players and mini computers, most people have at least one time－telling tool with them. Since these small machines are so common, will people stop wearing the 500－year－old watches? According to some people, yes. A teenager says it's unnecessary to wear a watch. Many young people agree and use their mobile phones to tell time. Louis Galie, a president, said that fewer young people wear watches today than five years ago.

However, watchmakers say that watches get popular again when people reach their 20s and 30s. By then, they want to spend money on a nice time－telling tool which doesn't just keep good time. For this reason, the watch industry has become an accessory business(配件业) in recent years.

Today's watches offer a lot of uses that meet the need of almost any personality(个性). They can be used as compasses(指南针), calendars, and even USB drives...

People are always trying their best to create new kinds of watches. A certain watchmaker business makes watches that don't even look like watches. Their popular model uses different color lights to tell the time. Another watchmaker business, makes a “handless” watch, using a ring of circles to keep time. This watch makes people talk a lot about modern watches.

Whether a watch expresses fashion sense, creative ability or a love for sports, people want their time－telling tools to be beautiful, fashionable and practical. All in all, a watch has become more important than the time it tells.
