中考真题2024年四川省资阳市阅读理解C篇-北斗卫星系统:全球导航的东方力量

This year, we celebrate 30 years since China started to build its Beidou Navigation Satellite System (BDS, 北斗卫星导航系统). It took its name from the Big Dipper stars, a group of seven bright stars in the sky.

In 1994, China began building the BDS, so it wouldn’t have to use navigation systems from other countries. It’s a lot safer this way. In 2020, the BDS was completed. This achievement made China the fourth to have its own navigation system after the US, Russia and the European Union.

The BDS does not just show where you are. It’s the first to let you send messages where there is no phone signal (信号). It has also played an important role in disaster prevention and response (防灾救灾). It even helps farmers in China by providing information for planting, which makes farming smarter.

The BDS is more than a system. It shows China’s ability in science and technology. Now over 120 countries and areas are using it. Wherever you are, the BDS is there to help you find your way.
