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. Read and learn Read the text and learn the key words and phrases in it. navigation /ˌnævɪˈɡeɪʃn/ n. 导航 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 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. Read and learn Read the text and learn the key words and phrases in it. GPS /ˌdʒiː piː ˈes/ abbr.

Think and talk Why did China spend so many years developing BDS? What good qualities do the BDS scientists have? What can we learn from them for our schoolwork? What can we do now to make our country better in the future? We’ve learned a lot about BDS today. It’s really amazing, isn’t it? Yes. It took Chinese scientists many years to build it. That’s true. So why did China spend so many years developing BDS? Because we didn’t want to depend on other countries. We needed our own navigation technology. Make and share Make up a conversation based on your discussion and share it with the class. I agree. Then what good qualities do the BDS scientists have? They are hard-working and they never give up. They also work well as a team. Make up a conversation based on your discussion and share it with the class. That’s great. What can we learn from them for our schoolwork? When we meet difficult problems, we should keep trying instead of giving up. We can also help and learn from classmates. Right. What can we do now to make our country better in the future? We should study hard now and keep our love for science. Maybe we can create new things one day. Make and share Exercise 1. Many shared bikes depend on high‑precision ____________ (navigate) services. 2. More ____________ (technology) skills are important for young scientists. 3. A great invention __________ (require) plenty of time and patience. 4. Young inventors _________ (aim) to create useful things for people around us. 5.
