Did you ever imagine flying over the city in an air taxi that has no pilot? Do you believe it can take you from place to place in minutes? It sounds like science fiction, right? Well, not anymore.
An electric vertical take-off and landing (eVTOL, 电动垂直起降) aircraft (飞行器), also known as an air taxi, completed its first inter-city flight in Guangdong on Feb 27. The eVTOL aircraft started its journey from Shenzhen to Zhuhai, completing the 55-kilometer trip in about 20 minutes. This flight is an important development of this exciting new form of transport.
Air taxis use high technology to take off and land vertically like a helicopter, which doesn’t need long runways. Instead of using traditional combustion engines, air taxis use electric motors. These air taxis have propellers placed all over them to help them stay balanced. They also use lithiumion batteries to store electricity, letting them fly far and fast. With a central command center that keeps an eye on the flight, some of them can fly without a pilot.
There is no doubt that air taxis can help improve heavy traffic, with their direct point-to-point travel saving valuable time for urban people. Except this benefit, as an eco-friendly choice, air taxis produce fewer emissions than traditional cars, improving urban air quality.
However, air taxis also need special places to take off and land, which means they need eVTOL airports called “vertiports”. Now researchers are trying to make full use of the existing (现有的) small airports to serve as “vertiports”. And with plans to fly at low altitudes (纬度) in cities, there’s still much work to be done to keep everyone safe.
1.1. Why does the author use the questions in paragraph 1?
A To carry out a survey.
B To show the author’s dream.
C To interest readers.
D To begin a science fiction.
解析:选C。C 细节理解题。作者开篇用设问,目的是吸引读者注意力,激发阅读兴趣,自然引出下文对空中出租车的介绍,A、B、D均不符合写作意图。
2.2. What helps air taxis stay balanced?
A A helicopter.
B Propellers.
C Lithiumion batteries.
D Combustion engines.
解析:选B。B 细节理解题。原文第三段明确指出,空中出租车周身配备的螺旋桨能帮助其保持平衡,A直升机、C锂电池、D内燃机均无此功能。
3.3. What does the underlined word “benefit” mean?
A Problem.
B Choice.
C Way
D Advantage.
解析:选D。D 词义猜测题。前文提及空中出租车可缓解交通拥堵、节省时间,这是其优势,“benefit”在此处意为“优势、好处”,与advantage同义,A问题、B选择、C方式均不符。
4.4. According to the last paragraph, what may next researches focus on?
A How to fly higher and more safely.
B How to improve urban air quality.
C How to fly at low altitudes more safely.
D How to build more new airports for air taxis.
解析:选C。C 细节理解题。最后一段提到,空中出租车计划在城市低空飞行,仍需大量工作保障安全,这是后续研究的重点,A飞得更高、B改善空气质量、D新建机场均与原文不符。
5.5. What’s the best title of the passage?
A A new form of transport.
B The history of air taxis.
C The popularity of air taxis.
D The forms of transport.
解析:选A。A 主旨大意题。全文围绕空中出租车这一新型交通工具展开,介绍其首飞、原理、优势与挑战,B历史、C流行度、D交通形式均片面,无法概括全文。
