Recently, China made a big step in 6G technology. Purple Mountain Laboratories in Nanjing showed the world’s first outdoor 6G test network. This happened at the Global 6G Conference 2025.

The new 6G network works much better than 5G. It is over 10 times faster! Scientists used three drones (无人机) to test it. Workers could see the drones’ real-time movements on screens. The screens showed exact positions, speeds, and heights of the drones.

Dr. Huang Yongming explained how it works. The 6G base station sends signals to drones. When signals hit the drones, they bounce back. Computers then study these signals to find the drones’ locations.

Future 6G won’t just be fast — it can “see” things too! Like radar, it can detect objects up to 1 kilometer away. Professor You Xiaohu said this combines communication and sensing. The same base station can both send messages and find objects.

This technology will help many areas. Delivery drones can fly safer in cities. It can also stop illegal drones in protected areas. The system can track drones while keeping communication with them.

Chinese scientists say this is just the beginning. The 6G test network will support new technologies and future industries. It shows China’s strong ability in creating next-generation communication systems.

1.1. Where was the world’s first outdoor 6G test network shown?

A In Beijing.

B In Shanghai.

C In Nanjing.

D In Guangzhou.

解析：选C。C 细节理解题。根据第一段的“Purple Mountain Laboratories in Nanjing showed the world’s first outdoor 6G test network.”可知，全球首个6G通智感融合外场试验网是在南京公开的。故选C。

2.2. What can be inferred from the use of drones in 6G testing?

A Drones can test 6G everywhere.

B 6G needs lots of drones to run.

C 6G can monitor real-time data.

D Drones improve 6G’s quality.

解析：选C。C 细节理解题。根据第二段的“Workers could see the drones’ real-time movements on screens. The screens showed exact positions, speeds, and heights of the drones.”可知，通过无人机测试，6G能够实现对实时数据的监测。故选C。

3.3. How does the 6G base station find drones’ locations?

A By taking photos of drones.

B By studying bounced signals.

C Using satellite maps directly.

D Following drones with cameras.

解析：选B。B 细节理解题。根据第三段内容可知，基站通过发射信号并接收回波来分析无人机位置。故选B。

4.4. What does the underlined word “see” in Paragraph 4 probably mean?

A Detect objects.

B Send messages.

C Take pictures.

D Control robots.

解析：选A。A 词义猜测题。根据第四段划线单词后文“Like radar, it can detect objects up to 1 kilometer away.”可知，像雷达一样，6G能对1公里外的物体进行“检测”，即此处“see”指6G的“感知/探测”功能。故选A。

5.5. What is the main idea of Paragraph 5?

A 6G helps delivery drones.

B 6G stops illegal drones.

C 6G easily tracks drones.

D 6G helps in many fields.

解析：选D。D 段落大意题。根据第五段内容可知，6G技术在多个方面有帮助，如让送货无人机在城市飞行更安全、阻止保护区内非法无人机以及跟踪无人机并保持通信等。故选D。
