Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion of the annual session of the National People’s Congress that WiFi should not be provided on high-speed trains, as it might harm communication signals (信号) of trains and would also cost a lot in keeping trains in good condition. He also encouraged passengers to enjoy the views, instead of fixing their eyes on the tiny screens of smartphones and laptops. However,Beijing Youth Dailysaid it should be market demand that decides whether the WiFi is offered on the trains or not.

An increasing number of people, especially young white-collar workers, are addicted to their smartphones rather than face-to-face communications, thanks to the extensive WiFi coverage across the country. ThatjustifiesWang’s disagreement to the offering of WiFi on high-speed trains, because they shouldn’t depend on high-tech devices. It is also obvious that passengers on trains without free WiFi will use their smartphones and other mobile devices less. However, whether the trains should provide a free WiFi service mainly depends on customer demand.

In other words, the China Railway Corp has to obey relevant market rules, and provide technologically possible services to passengers if that is what they want. It cannot turn a blind eye to customers’ wants.

Free WiFi, in fact, is already offered on a lot of buses and coaches. This is a natural response to their competition with trains (especially high-speed ones), which are significantly faster and safer. The bus companies have been forced to improve their services to survive. So it requires proper guidance, not total “no” on the use, to make up for the negative effects of high-end technologies, such as people’s increasing addiction to smartphones.

A.make the communication signals harmful

An electric flying vehicle called Skai was shown yesterday near Los Angeles, California. Skai is made by Alaka’i Technologies. The vehicle has six rotors(旋翼)on the roof and seats inside for five people.

Like a drone(无人机), the vehicle from Alaka’i Technologies takes off and lands vertically(垂直地). It’s one of many similar electric flying vehicles in production, including ones from Boeing and Airbus. But most of them are powered by batteries, which can add a lot of weight. The Skai instead uses very light hydrogen fuel cells to run its rotors, giving it a range of 400 miles(644 kilometers)and the capacity to carry 1,000 pounds(454 kilograms)in people or goods, the company says.

Alaka’i says it’s planning a test flight near its Massachusetts headquarters. It will be flown by an on ⁃ board pilot(飞行员), but the technology exists to eventually fly it remotely and even autonomously. However, it will be years before the Federal Aviation Administration(FAA)allows the autonomous flight of passenger vehicles, said Thaddeus Lightfoot, who helps companies navigate FAA rules.

“Drone⁃ like vehicles such as the Skai must first simply prove their airworthiness, like any common plane. After that, getting commercial certification is another complex process. The technology is interesting, but the regulatory road will be very long,”said Lightfoot, adding that the idea of allowing people to fly in a large aircraft without a pilot is“well outside the current regulatory system.”

Hanvey, CEO of Alaka’i Technologies, said that it could take at least a decade before the company realizes his goal of electric flying vehicles ferrying passengers over major cities at   nearly 120 mph. Before that, he hopes to see Skai aircraft used by first responders to send in food or water following disasters like hurricanes or wildfires. It could also serve as a mobile cell tower, staying in the sky for up to 10 hours over a neighborhood to provide communication services, he said.

【小题1】What is the advantage of the Skai?
A.It is quite light.B.It uses batteries.
C.It carries more people.D.It lands autonomously.
【小题2】What can we infer about the pilotless flight of passenger vehicles?
A.It costs a lot.
B.It saves energy.
C.It is not readily available now.
D.It will soon get approved by FAA.
【小题3】According to Thaddeus Lightfoot, what should the Skai do first?
A.Prove its safety to fly.B.Conduct a test flight.
C.Get a commercial license.D.Obey the International Air Law.
【小题4】Where is the Skai probably first used according to Hanvey?
A.In the countryside.B.In some major cities.
C.In mountainous areas.D.In disaster⁃stricken areas.
