China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots, self-driving cars, and the Internet of things.
The GSMA said that China’s three major mobile operators — China Unicom, China Mobile, and China Telecom—are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
A One of the major distinguishing factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China’s seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation’s total connections will be 5G, according to GSMA. This compares to 50 percent in the US,49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1.What will 5G bring?
A.A completely new pattern for daily life.

2.What is the future of 5G in China?

My senior high school life started with military training(军训). It consisted in two parts: the theory exam and the physical training, which was lasted about two weeks. The latter was much tough than the former. Dressed in green uniforms and exposing to the sun, we had to follow the soldier daily routine and go through hard training. Each morning, we had to get up and fold quilts rapid. We should finish our meals in limited time, too. Then I think it unbearable. Besides, now looking back, I find it necessary. It is the military training which teaches me how to bear hardship and lead better life.
