第六课时　Section B (3a—Self Check) Unit 6　When was it invented ？ 1 一、阅读理解 I like digital(数字的) watches, but I like the old watches with their slow moving hands and ticking sounds best. I think mechanical watches(机械表) are fantastic. There is a long history of watches. Many years ago, ships had trouble navigating(导航) without a dependable clock on board(甲板). In 1500, a man invented a clock that would work on board. A special piece of metal was used to keep it working. Soon, pocket watches became available, but they were expensive. Owning a pocket watch meant you were rich and probably important. But by the 1800s, owning a pocket watch had become quite common. In 1795, Breguet who was born in Switzerland invented the tourbillon(陀飞轮) watch. Today，tourbillon watches are still produced. In fact, they are quite expensive. It has up to 400 moving parts inside and can take up to a year to make. Sometimes people don't realize how amazing these mechanical watches are. Sure, you can buy a digital watch for almost nothing, and it will still give you very accurate time. But remember, today's watches are the result of hundreds of years of development. Watches keep us in touch with the world because the accurate time keeps everything running in order.
