These systems use satellites in space to send signals to receivers on Earth. By measuring the time it takes for signals to travel, a receiver can calculate its exact location. The most well-known GNSS is the United States' GPS (Global Positioning System), which was developed by the U.S. Department of Defense. It became fully operational in 1995 and has been the leading navigation system for decades. Russia's GLONASS is another major system, and the European Union has developed Galileo. China's Beidou Navigation Satellite System (BDS) is the newest of the major global systems. BDS was developed to meet China's growing need for secure and reliable navigation services. It is unique because it uses both geostationary and non-geostationary satellites, which gives it better coverage in certain regions. The system has been widely used in transportation, agriculture, and disaster management. With the completion of BDS-3 in 2020, it now provides global coverage. The development of GNSS has greatly improved the accuracy and reliability of navigation. These systems are used not only for personal navigation but also for shipping, aviation, and scientific research. They have become an essential part of modern life. ( )1. What do Global Navigation Satellite Systems provide? A. Only positioning services. B. Positioning, navigation, and timing services. C. Only navigation services. D. Communication services. ( )2. When did GPS become fully operational? A. In 1980. B. In 1995. C. In 2000. D. In 2010. ( )3. What makes Beidou unique compared to other GNSS? A. It is the oldest system. B. It uses both geostationary and non-geostationary satellites. C. It only covers Asia. D. It is the cheapest system. ( )4. In which areas is BDS widely used? A. Only in transportation. B. In transportation, agriculture, and disaster management. C. Only in aviation. D. Only in scientific research. ( )5. What is the main idea of the passage? A. GPS is the best navigation system. B. There are several global navigation systems, and Beidou is the newest one. C. Navigation systems are not important. D. Only China has a navigation system. B   My Experience with Beidou Navigation Last summer, my family and I went on a road trip to the countryside. We decided to use a navigation app on my father's phone to find the way. I was surprised to see that the app was using China's Beidou Navigation Satellite System instead of GPS. My father explained that Beidou is now widely used in China and offers very accurate positioning. As we drove, the navigation gave us clear directions. It told us exactly where to turn and even warned us about traffic jams ahead. At one point, the road was closed for construction, but the navigation system quickly found an alternative route. We arrived at our destination without any problems. My father told me that Beidou was developed by Chinese scientists and engineers. He said that it took many years of hard work to make it so reliable. He also mentioned that Beidou is used not only for navigation but also for farming, fishing, and even disaster rescue. I felt proud that China has its own navigation system. It made me realize how much technology can improve our lives. I hope Beidou will continue to develop and become even better in the future. ( )6. What did the writer's family use for navigation on their trip? A. A paper map. B. A navigation app using Beidou. C. A GPS device. D. A compass. ( )7. What did the navigation system do when the road was closed? A. It told them to stop. B. It found an alternative route. C. It turned off. D. It gave an error message. ( )8. What did the writer's father say about Beidou? A. It was developed by American scientists. B. It took many years of hard work to make it reliable. C. It is only used for navigation. D. It is not very accurate. ( )9. Besides navigation, what else is Beidou used for? A. Cooking. B. Farming and fishing. C. Entertainment. D. Schooling. ( )10. How did the writer feel about Beidou? A. Disappointed. B. Proud. C. Worried. D. Indifferent. C   The Importance of Independent Navigation Systems Having an independent navigation system is very important for a country's security and development. A nation that relies on another country's navigation system may face risks if the system is ever disrupted or used against them. That is why China decided to develop its own Beidou Navigation Satellite System. One of the main reasons for developing an independent system is security. A military or country that uses GPS is dependent on the United States. If there is a conflict, the U.S. could potentially disable GPS in certain regions. By having Beidou, China can ensure its military and civil services have reliable navigation at all times. Another reason is economic development. A national navigation system supports many industries. Transportation, logistics, and agriculture all depend on accurate positioning. By having its own system, China can save money and avoid paying for foreign services. It also creates high-tech jobs for Chinese scientists and engineers. Finally, having an independent navigation system is a matter of national pride. It shows that a country has the technological capability to compete on a global level. Beidou is a symbol of China's progress in science and technology. It inspires young people to pursue careers in engineering and innovation. ( )11. What is the main idea of the passage? A. GPS is the best navigation system. B. Independent navigation systems are important for security, economy, and pride. C. Beidou is only used by the military. D. China should not have its own navigation system. ( )12. Why is an independent navigation system important for security? A. It is cheaper. B. It prevents dependence on other countries. C. It is more accurate. D. It is easier to use. ( )13. How does Beidou support economic development? A. By providing free services. B. By supporting industries like transportation and agriculture. C. By creating new languages. D. By building new roads. ( )14. What does Beidou symbolize? A. China's progress in science and technology. B. China's food production. C. China's population growth. D. China's ancient history. ( )15. What does the author suggest at the end? A. Beidou is not important. B. Beidou inspires young people to pursue careers in engineering. C. Only scientists should use Beidou. D. Beidou should be replaced by GPS. 八、完形填空（阅读下面的短文，从每题所给的A、B、C、D四个选项中选出最佳选项） China's Beidou Navigation Satellite System (BDS) is one of the best navigation systems in the world.
