We have recently heard some interesting ways that 5G technology might change our lives in the future. 5G promises internet speeds between 50 to 100 times faster than 4G systems. Such improvements are sure to be popular with 5G users worldwide. While it is said to start only in some few areas of the United States this year, much of the rest of the world is not expected to receive this service until 2023.
One project in Britain, though, is already testing the superfast technology, but not on humans. Instead, the experimental subjects (实验对象) are unlike the group of internet users—cows. The system connects the animals to 5G in an effort to automate (使自动化) the milking process.
The project was developed by American technology company Cisco Systems. Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G-connected devices (设备) that link up to a robotic milking system. The system uses sensors (传感器) and machine learning to fully automate the process.
System designers say technology takes over after a cow is ready to be milked and walks toward an automatic gate. The device is designed to recognize each cow. It then positions devices to the right body position for milking. During the process, machines offer food for the cow as a reward.
One of the test areas is in the town of Shepton Mallet in southwest England. There, about 50 of the farm’s 180 cows are fitted with 5G smart collars(智能项圈) in ear sensors. Project officials say the devices do not harm the cows and the sensors help farmers immediately find any problems or health concerns.
Duncan Forbes, the project leader, told Reuters that so far, he thinks the project shows the farm’s 180 cow operations can be greatly improved with 5G technology.
Forbes added that the experiment provides strong evidence that 5G technology can be widely used in the future“not just on farms, but in rural communities right across the country”.
1. What do we know about 5G technology from the first two paragraphs?
A. It has changed our lives.
B. It has more users than 4G.
C. It has not been widely used.
D. It is used on cows in the USA.
2. What is Paragraph 4 mainly about?
A. The introduction of 5G devices.
B. The milking process with 5G technology.
C. The purpose of system designers.
D. The way machines provide cows with food.
3. Why are some cows fitted with ear sensors?
A. To recognize every cow.
B. To judge the position of the cow.
C. To reduce the harm from devices.
D. To find health problems in cows.
4. What is Forbes’ attitude to the future of 5G technology?
A. Doubtfu1. B. Hopeful.
C. Disapproving. D. Uncaring.
