An electric flying vehicle called Skai w...

    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 miles644 kilometersand the capacity to carry 1,000 pounds454 kilogramsin 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 AdministrationFAAallows 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.

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.

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.

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.

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 disasterstricken areas.

 

1.A 2.C 3.A 4.D 【解析】 这是一篇说明文。短文介绍了一款氢动力空中出租车Skai的相关信息。 1.细节理解题。由第二段的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.”可知,但是大多数都是由电池供电的,这会增加很多重量。相反,Skai使用非常轻的氢燃料电池来驱动它的转子。所以the Skai的优点在于其重量很轻。故选A项。 2.推理判断题。由第三段However, it will be years before the Federal Aviation Administration(FAA)allows the autonomous flight of passenger vehicles可知,然而,美国联邦航空管理局(FAA)还需要数年时间才能允许客运车辆自主飞行。所以判断出关于无人驾驶的客车飞行,我们能推断出现在还不能使用。故选C项。 3.细节理解题。由第四段Drone-like vehicles such as the Skai must first simply prove their airworthiness, like any common plane.可知,像 skai 这样的无人驾驶飞行器,必须首先证明它们的适航性,就像任何普通飞机一样。所以根据撒迪厄斯 · 莱特福特的说法,the Skai首先应该证明它飞行的安全性。故选 A项。 4.细节理解题。由最后一段Before that, he hopes to see Skai aircraft used by first responders to send in food or water following disasters like hurricanes or wildfires. 可知,在此之前,他希望看到Skai飞机被第一批回应人员用来在飓风或野火等灾难发生后运送食物或水。所以根据汉维的说法,Skai最早最先用在受灾地区。故选D项。

    Frederick Phiri is the junkart king of Zambia: at just 22, he started to earn an international reputation for being able to make complex and elegant sculptures from scrap metal(金属废料) found in his community.

Phiri’s father died when he was starting primary school. Then his mother abandoned him and he had to stay with his grandfather. His grandfather paid for his schooling through primary school but when he entered secondary school, he had to get various jobs to pay for his fees. Yet even in school, he was always drawing and making things in class.

After graduating, he did what he could to support himself by making animal sculptures from wires and sold them to tourists. His work was so popular that it caught the eye of Karen Beattie, director of Project Luangwa, a nonprofit dedicated to education and economic development in central Africa.

“I introduced him to a local welder(焊工),”Beattie told Newsweek.

In 2017, Phiri worked with welder Moses Mbewe during the rainy season, helping to make a complex set of doors for Project Luangwa. The piece sparked an idea in Beattie’s mind:“I handed him a bunch of scrap metal and said,‘Make something with this.’And he did. It was wonderful.”

Today, Phiri continues his art, using pieces of junk people bring him — keys, broken bike chains, old metal plugs and whatever scrap metal is lying around. He then turns the junk into abstract animals — elephants, cranes, giraffes, chameleons — and sells them at Project Luangwa headquarters. The community has recognized his talents.

“My dream is to earn enough to study art at the Evelyn Hone College in Lusaka and be able to make a living from it,”Phiri said“. And then to make very large sculptures.”

1.What is Phiri known for?

A.Serving his community.

B.Collecting works of art.

C.Being the king of Zambia.

D.Turning trash into treasure.

2.What can we learn about Phiri from paragraph 2?

A.He had an unhappy childhood.

B.He paid for his primary school.

C.He had to support his grandfather.

D.He missed school to do parttime jobs.

3.How does Phiri feel about his future?

A.Uncertain. B.Confident.

C.Depressed. D.Satisfied.

4.What can be a suitable title for the passage?

A.A Rough Road to Success

B.The Junk Art King of Zambia

C.A Young Man’s Wildest Dream

D.The Modern Junk Works of Art
