Question

【題目】 The $380,000 aircraft, called the "Speeder", will be able to reach at least 150 miles per hour and have a 45-mile range and fly as high as 15,000 feet when it is on sale next year, according to David Mayman, CEO of JetPack Aviation, one of the companies that create and sell flying vehicles. This motorcycle can take off vertically (垂直地) from the grassland or a street and land on the other side of the city in a similar position. This idea has always been treated like science fiction.

At some point, the Speeder could be adapted to use electric energy, which is more environmentally friendly, but for now, Mayman said, no battery cells come close to the speed and potential power created by jet engines. Besides, like other developing similar craft, currently the Speeder will only be used for recreation and sport until laws and regulations begin to change in America.

Mayman argued that there was a large role for the Speeder to play in both civilian and military life. He said his company has been working for several years to develop a jet pack that could be used by Special Forces soldiers. As their cost continued to increase, he said, engineers began designing a personal aircraft that eventually turned into the Speeder.

Mayman said that the aircraft could be used to transport heavy loads or move soldiers on and off the battlefield, especially in areas too dangerous for helicopters. Unlike other flying vehicles, the craft is small enough to sit on the back of a boat or can be easily delivered by a common fighting vehicle.

Answer 1

【答案】

【1】D

【2】B

【3】B

【4】D

【解析】

本文是一篇說明文。作文章主要向我們介紹了架價值38萬美元的飛機——Speeder的相關(guān)信息。

【1】推理判斷題。根據(jù)文章第一段中的This motorcycle can take off vertically (垂直地) from the grassland or a street and land on the other side of the city in a similar position.可知，這種摩托車可以從草地或街道上垂直起飛，在城市的另一邊以類似的位置降落。由此可知，它可以在寬敞的地方起落，因此在學校的操場上也可以起落。故選D。

【2】推理判斷題。根據(jù)文章第二段中的Besides, like other developing similar craft, currently the Speeder will only be used for recreation and sport until laws and regulations begin to change in America.可知，除了像其他開發(fā)類似工藝一樣，Speeder目前僅用于娛樂和體育，直到法律法規(guī)開始在美國發(fā)生變化。由此可知，政府的政策限制了Speeder的使用。故選B。

【3】推理判斷題。根據(jù)文章第三段中的He said his company has been working for several years to develop a jet pack that could be used by Special Forces soldiers. As their cost continued to increase, he said, engineers began designing a personal aircraft that eventually turned into the Speeder.可知，他說，他的公司多年來一直致力于開發(fā)一種可以供特種部隊士兵使用的噴氣背包。他說，隨著成本的持續(xù)增加，工程師們開始設(shè)計一種個人飛機，最終將其改裝成Speeder。由此可知，Speeder最初是為軍隊設(shè)計的。故選B。

【4】細節(jié)理解題。根據(jù)文章最后一段中的Unlike other flying vehicles, the craft is small enough to sit on the back of a boat or can be easily delivered by a common fighting vehicle.可知，與其他飛行器不同的是，這種飛行器足夠小，可以安裝在船的后部，也可以很容易地由一輛普通的戰(zhàn)車運載。由此可知 與其他飛行器相比，這種飛行器的優(yōu)勢是它的體積小，使它方便。故選D。
