Unit 3 The Internet 能力提升素养练习 Ⅰ.阅读理解 A We have heard some interesting ways that 5G wireless technology might change our lives in the future. 5G, short for the 5th generation mobile communication technology, promises Internet speeds between 50 to 100 times faster than 4G systems. One project in Britain is already testing this super fast technology on an unlikely group of Internet users—cows. The project was developed by American technology company Cisco Systems. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G connectivity in rural areas around the world. Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G­connected devices (装置) that link up to a robotic milking system, which uses sensors (传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward. Other 5G technology tools include automated brushes that turn on when the cow rubs up against them. Sensors also control the amount of light to the cows' living areas depending on the weather. And an automatic feeding system makes sure the animals always get enough to eat. Duncan Forbes, head of the project, told Reuters that the project shows the farm's cow operations can be greatly improved with 5G technology and that the experiment provides strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in rural communities across the world. 1．What is the purpose of Cisco Systems' program? A．To win financial support from British government. B．To test the effects of 5G technology on animals. C．To promote its technological development in Britain. D．To expand the future use of 5G
