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(配件業(yè)) in recent years.

Today's watches offer a lot of uses that meet the need of almost any personality(個(gè)性). They can be used as compasses(指南針), 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.

Today, people want to do sports and exercise to keep healthy. But some of them have some wrong ideas about it.

◆ “A plate of chicken is a good meal before games because it has much energy.”

The best meal before games should have carbohydrates (碳水化合物). Food like potatoes, bread, bananas are rich (富含……的) in it, but chicken and meat are not.

◆ “ 54 ”

You must have some water when you exercise. And after exercising, you also need to have some water. If you don’t drink any water, then you may feel tired.
