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.

Advance train tickets may also be available for first class travel,meaning you can enjoy all the perks (特殊待遇) of a higher standard of train travel at a good price.

Could you imagine what it would be like if there were no other ways to get around except by using your feet? Not only would you wear out(磨破)a lot of shoes but it would take you a long time to get anywhere.

【小题1】 But that’s just the wheel; did you know that the earliest boats were dugout canoes (独木舟)?People lit a fire on a big log (圆木) and then put the fire out and dug out the burned wood!

Then there were the Egyptians, who invented the sailing boat, but this could only be used in one direction. 【小题2】 Later the clever Romans came along and built their famous network of roads across the Roman Empire. 【小题3】

Some of the roads did not last very long and they soon became dirt tracks (路). People travelled on roads by wagon (马车), but most things would be taken by sea in the 16th century. In the 19th century, some of the forms of transport that you know today were invented—the bike and the car. 【小题4】 The first underground railway in the world was built in London.

Horses have long pulled tourist carts through Jordan’s ancient city of Petra, but animal rights groups are driving a project to start replacing them with electric vehicles.

A small team of 10 rechargeable e-carts now take visitors through the rose-colored road leading to the famed capital of the Nabateans, which dates back to the first century BC.

“The e-cart produces no pollution or smoke and the change has reduced the cases of animal mistreatment,” said Suleiman Farajat, head of the Petra Development and Tourism Regional Authority. The new golf buggy-style (马车式) electric vehicles have less impact on the surroundings because the horse cart wheels used to hit the sides of the road. The horse waste also caused a bad smell in the place, and cleaning it was not easy.

Animal rights group PETA, which had blamed the use of the overworking animals, has described the project as a major first step to protect working animals. The group hopes to work with officials toward the day when there will be only animal-free transportation at Petra.

The change has also been well received for another reason — helping to make the UNESCO World Heritage Site accessible to elderly and disabled visitors with the newly designed e-carts. Austrian tourist Rudy, 43, who uses a wheelchair, said he had repeatedly postponed a visit, but was now very happy to have made the trip. “Not only disabled people but also people who have difficulty walking for a long distance now have a chance to see this amazing place,” he said.

For now, the Petra authority says it will keep some of the horses to preserve the character of the place, as it is a world heritage site.

【小题1】What is the disadvantage of using horse carts?
A.Their speed is too slow.B.Their horses waste food.
C.They are difficult to clean.D.The wheels damage the road.
【小题2】What do we know about the animal rights group?

B.They sing high praise for keeping horse working hard.
C.They are happy to see the progress in animal protection.

【小题3】What makes it possible for Rudy to visit Petra?
A.His improved health.B.The better environment.

【小题4】What is the text mainly about?
A.E-carts replace horse carts in the ancient Petra.B.Animal rights group calls for protection of animals.
C.Government takes measures to protect heritage sites.D.Convenient traffic helps tourism in Jordan to boom.
