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.

One of the most distinguishing actors 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.
B.Realizing the potential in many new services.
C.Excellent networks and national safety.
D.Amazing speeds for public transportation.
2. What is the future of 5G in China?
A.It may be lack of government support.
B.It will move forward slowly.
C.It will develop rapidly.
D.It may fall behind Europe.
3. Which of the following best explains "erect" underlined in paragraph 4?
A.set upB.bring upC.turn upD.pick up
4. What can we infer from the last paragraph?
A.Chinese cannot own 5G in 2025.
B.More than half Koreans use 5G in 2025.
C.Only five countries will have 5G in 2025.
D.Europe will pay little attention to 5G in 2025.

文章大意:本文是说明文。瘫痪的男子在大脑和脊髓植入物的帮助下恢复了站立和行走的能力。

【推荐2】A man paralyzed (瘫痪的) in 2011 has regained the ability to stand and walk with the help of implants (植入物) placed in his brain and spinal cord (脊髓).

The patient, 40-year-old Gert-Jan Oskam of the Netherlands, was told he would never walk again after a biking accident. Now, using the implants, “we’ve read the thoughts of Oskam and translated these thoughts into stimulation of the spinal cord to reestablish voluntary movement,” said Gregoire Courtine, a neuroscientist at the Swiss Federal Institute of Technology.

The technology “enables natural control over the movements of his legs to stand, walk, and climb stairs,” the study authors write. Oskam can walk more than 330 feet at once and stand for several minutes without using his hands for support. “A few months ago, I was able, for the first time after over ten years, to stand up and have a beer with my friends,” Oskam says. “That was pretty cool.”

The new technique involved placing two implants in Oskam’s brain. When he wants to move, the implants read his brain signals and send that information to sensors on a device on his head. A computer uses these signals to predict how Oskam intends to move, then turns his intentions into commands and sends these commands to another implant in the spinal cord. Finally, the spinal implant stimulates Oskam’s muscles according to his intended movement. Through this “digital bridge,” the researchers re-opened a line of communication between Oskam’s brain and spinal cord.

For now, the device is still at the experimental stage. Next, the researchers would like to be able to make the device’s hardware, which Oskam carries in a backpack, more compact (小巧的). They hope the technology can one day be used to help people regain the capacity for other movements and bodily functions. Harvey Sihota, CEO of the U.K. charity Spinal Research, says the technology still has a long way to go before becoming available to the public, but the results are “very encouraging.”

1. How might Oskam feel after the implants were put in?
A.Cheerful.B.Secure.C.Disappointed.D.Uncomfortable.
2. What provides direct stimulation to Oskam’s muscles in the new technique?
A.The brain implants.B.Sensors on his head.
C.A computer.D.The spinal implant.
3. What are the researchers most likely to do next concerning the device?
A.Mass-produce it.B.Test it on a larger sample size.
C.Explore its other functions.D.Improve its hardware.
4. What can be the best title for the text?
A.Brain implants cure paralyzed man completely
B.Paralyzed man walks again using his thoughts
C.Digital bridge connects paralyzed men closely
D.New technology offers hope for biking accident victims

【推荐3】A research has shown that nearly 90 percent of traffic accidents are caused by human errors. So our aim is a fully autonomous car that gets rid of the cause of most accidents: the driver. Researcher Hodgson points out, “For safety, the faster you can remove humans, the better, even if there are unfortunately a few accidents from new causes. It s a question of balancing the number injured or killed by autonomous vehicles with the people whose lives are potentially saved.”

It’s an idea that Elon Musk, chief executive of electric car company Tesla Motors, has long believed. His company are determined to be the first to deliver a fully autonomous vehicle to consumers. Last year, Musk announced that Tesla’s 2017 goal was “to do an example drive of full autonomy all the way from LA to New York…and have the car park itself.”

However, even Tesla admits that there are problems to overcome—the software needs further validation and the appropriate regulatory approval needs to be in place. Indeed, recent crashes of Tesla vehicles and Google cars confirm that the software isn’t ready yet.

The UK government appears committed to encouraging the development of autonomous vehicles. It’s supporting four city trials, publishing the Modem Transport Bill to reduce red tape around their introduction and adapting the legal system to take into account problems such as insurance liability when a human isn’t in control of a vehicle.

The insurance industry is similarly eager to help increase autonomy in cars. As the Association of British Insurers (ABI) points out, “More than 90 per cent of road accidents are caused by human error.” This costs motor insurers a shocking £20m per day in claims.

1. What difficulty does the company Tesla Motors have?
A.New inventions may cause more injuries and deaths.
B.The company lacks confidence to make new creations.
C.The software should be made officially acceptable.
D.The traffic regulation has proved unreasonable.
2. What is the UK government’s attitude to autonomous cars?
A.Ambiguous.B.Positive.
C.Cautious.D.Disapproving.
3. What is the main idea of the last paragraph?
A.Insurance companies would like to support autonomous cars.
B.Human mistakes may be the key cause of traffic accidents.
C.Traffic accidents wastes insurance companies quite a lot.
D.Motorists are surprised to hear about autonomous cars.
4. What is the author’s purpose in writing the text?
A.To show his deep love for autonomous cars.
B.To introduce a new development in technology.
C.To amuse readers with funny examples.
D.To provide a persuasive argument against autonomy.
