China has a self-developed navigation system — BeiDou. Pair work. Look at the pictures and discuss what BDS can be used for in our daily life. 5 When people go hiking in mountains or forests, BDS can show their real‑time position on the map and help them find the right way. It keeps them from getting lost in the wild. After disasters, BDS can quickly find the positions of people in danger. With its help, rescuers can reach trapped people faster and save more lives. 6 It records where each bike is placed. Managers can check the locations of bikes easily and users can find nearby shared bikes conveniently on mobile apps. BDS offers position information for fishing boats on the sea. Fishermen can know exactly where they are. If they meet danger at sea, they can send signals for help with BDS, so it protects fishermen’s safety. 7 What do you know about the BeiDou System? Pre-reading Read the text. Up in the sky, there are many man-made inventions that help us find the right direction on 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 navigation 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 first step in China’s three-step BDS program. The second step was to bring BDS to more countries. This was a big goal and required even more ef forts. 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 around the world. To compete with the navigation systems from Europe and America, the Chinese team worked harder than ever. Finally, in 2020, BDS-3 was completed and began providing services worldwide. China’s navigation satellite system is named “BeiDou” after the seven bright stars that the ancient Chinese used for navigation. In the future, China will continue to improve BDS and provide better navigation services for the whole world. Read the text and retell the past, present and future of China’s BDS briefly in your own words. China’s BeiDou Navigation Satellite System Past Present Future In 1994, China decided to develop its own navigation system. BDS-1 was put into use and began providing services for people in China in 2003; BDS-2 was completed in 2012, covering the Asia-Pacific. BDS-3 was completed in 2020, providing global services. China will continue to improve BDS and provide better navigation services for the whole world. Para 1 Para 2 Para 3 Para 4 Para 5 What BDS is. The starting of BDS. BDS-2 serving the Asia-pacific area. BDS-3 serving the world. The meaning and future of BDS. Read the text and answer the questions. What navigation system did the world depend on in the early 1980s? When did China decide to develop its own navigation system? The world depended on America’s GPS. In 1994. Read the text and answer the questions. Where does the name “BeiDou” come from? Why did China decide to develop BDS? It is named after the seven bright stars that ancient Chinese used for navigation. Because in the early 1980s, the world depended on America’s GPS for navigation. China wanted to have its own independent navigation system. Read the text and answer the questions. What does “three-step BDS program” refer to? What can we learn from the engineers and scientists who developed BDS? Step1: BDS-1 served China. Step2: BDS-2 served the Asia-Pacific area. Step3: BDS-3 served the whole world. We can learn the spirit of hard work, teamwork and never giving up. Read the text again and complete the following chart.
