While-reading 03 Q: What is the main idea of the whole passage? It introduces______________________, ___________and ______of______________. Up in the sky, there are many man‑made inventions that guide us to go in the right direction on the Earth. Among them, China’s Beidou Navigation Satellite System (BDS) is one of the best. In the early 1980s, the world depended on America’s GPS (Global Positioning System) for navigation. However, in 1994, China decided to develop its own system. In the next 10 years, a research and development team worked day and night, doing experiments, running tests, and solving technological problems. Finally, in 2003, BDS‑1 was put into use and began providing services for people in China. This marked the beginning of and the first step in China’s three‑step BDS strategy. The second step was to include more countries in China’s BDS. This was a great aim and required even more efforts. Experienced engineers worked closely with younger ones, passing on successful experience and solving the problems one by one. In 2012, after nine years of hard work, BDS‑2 was completed. Its services covered the Asia‑Pacific area. Starting in 2015, the Chinese scientists aimed to make BDS work well at a global level. To compete against Europe and America, the Chinese team worked harder than ever. Finally, in 2020, BDS‑3 was completed and began providing services around the world. China’s navigation satellite system is named “Beidou” because it is the name for the seven bright stars that ancient Chinese used to find their ways. In the future, China will continue to improve BDS and guide the whole world to go in the right direction.c China’s BDS the development history name reason future Up in the sky, there are many man‑made inventions that guide us to go in the right direction on the Earth.
