Question

    The development of a V-shaped fuel-efficient airplane design known as the Flying-V will be funded by Dutch national carrier KLM Royal Dutch Airlines．

To improve the sustainability （持续性） of air travel, the Flying-V was developed by researchers at Delft University of Technology in the Netherlands, also known as TU Delft．

Its futuristic design puts the passenger cabin into the wings. It's said the plane will use 20% less fuel than the Airbus A350-9-while carrying a similar number of passengers．

"In recent years, KLM has developed as a pioneer in sustainability within its airline industry," said Pieter Elbers, CEO and president of KLM. "We are proud of our progressive relationship with TU Delft"．

"Air travel is contributing about 2.5% of global CO₂ emissions (排放物)， and the industry is still growing, so we really need to look at more sustainable airplanes," said TU Delft project leader Roelof Vos．

"We cannot electrify planes, as electrified airplanes become way too heavy and you can't fly people across the Atlantic on electric airplanes- not now, not in 30 years," Vos said. "So we have to come up with new technologies that reduce fuel burning in a different way."

"We've been flying traditional airplanes for decades now, but it seems like they are reaching the limit in terms of energy efficiency," he said."The new design actively contributes to the lift of the airplane, and creates less air drag."

The plane's increased fuel efficiency is largely a result of its design, Vos explained．

The researchers hope to fly a model this September, Vos said, while the new cabin design will be open to the public at Amsterdam Airport Schiphol in October. The completed plane is expected to enter service between 2040 and 2050．

【解析】

本文是一篇说明文。本文主要讲述了由荷兰国家航空公司荷航荷兰皇家航空资助的V型省油飞机的设计被称为" Flying-V"．

1.细节理解题。根据第四段“In recent years， KLM has developed as a pioneer in sustainability within its airline industry，”近年来，荷航已发展成为航空业可持续发展的先驱．可知，荷航在可持续发展方面发挥着重要作用。故选D。

2.细节理解题。根据第五段“Air travel is contributing about 2.5% of global CO₂ emissions （排放物）， and the industry is still growing， so we really need to look at more sustainable airplanes.”可知，航空旅行占全球二氧化碳排放量的2.5%，而且该行业仍在增长，因此我们确实需要研究更具可持续性的飞机。可知，需要可持续的飞机是为了减少全球CO2排放量。故选B。

3.细节理解题。根据倒数第二段“The plane's increased fuel efficiency is largely a result of its design， Vos explained．”沃斯解释说，飞机提高燃油效率的主要原因是其设计。可知，Flying-V节省能源是通过V型设计。故选A。

4.推理判断题。这是一篇说明文，文章开头第一段“The development of a V-shaped fuel-efficient airplane design known as the Flying-V will be funded by Dutch national carrier KLM Royal Dutch Airlines．”开门见山介绍了由荷兰国家航空公司荷航荷航荷兰皇家航空资助的V型省油飞机的设计被称为" Flying-V"。其余各段都在围绕Flying-V展开具体的细节介绍。因此本题选C。
