七、阅读理解。
(社会热点)On April 13,2025,China made a very important step in global communication technology. It launched the world’s first 6G integrated(综合的)communication-intelligence-sensing test network in Nanjing. Purple Mountain Laboratory developed this. This is a big jump from just having ideas about 6G to testing it in the real world.
The new 6G network can do two things. It can communicate and also sense like a radar(雷达). The base stations(基站)are both signal senders(信号发送器)and “smart radars”. They use wireless signals to find objects. For example,when testing drones(无人机),these stations could find the positions,speeds,and heights of three drones very accurately. The error(错误)was less than or equal to 3 cm. Compared with 5G,the 6G network is more than 10 times faster in communication. And each base station can support up to 1 million devices.
This technology will change our daily life. In low-altitude(低空的)delivery,drones can bring goods much faster. A 7. 4-km delivery only takes 13 minutes,which is three times more efficient. For the safety of cities,it can find illegal(非法的)drones in 5 seconds. This helps keep the airspace(空域)safe. In smart cities,traffic lights can change by themselves using real-time road information. In some test areas like Beijing,traffic jams are reduced by 35%.
China wants to be the leader in global 6G standards. It plans to start using 6G for business by 2030. This project also helps other industries,like satellite networks(卫星网络)and devices that use AI. Professor You Xiaohu,a famous scientist,said,“6G will change how people connect. It’s not just about being fast,but also about helping us know more about the world around us.”
This new development shows that China is becoming more and more important in high-technology. It gives us a look at a future:networks are faster,smarter,and more connected than ever.
