1、【 精品教育资源文库 】 Unit 4 Astronomy the science of the stars 单元加餐练 . 阅读理解 A (2017 全国卷 )Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle named the Transition has two seats
2、, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23gallon tank of gas and burns 5 gallons per hour in the air. On the ground,
3、 it gets 35 miles per gallon. Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But dont expect it to show up in to
4、o many driveways. Its expected to cost $279,000. And it wont help if youre stuck in traffic. The car needs a runway. Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making
5、the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards. Mann said Terrafugia was helped by the Federal Aviation Admini
6、strations decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots wou

11、to its goal of selling the flying car within the next year” 由此可知，飞行汽车快要变成现实了。故选 D。 B Pluto which famously was degraded from a “major planet” in 2006 captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system. P
12、lutos underdog discovery story is part of what makes it so appealing. Clyde Tombaugh was a Kansas far boy who built telescopes out of spare auto parts, old farm equipment and selfground lenses. As an assistant at Lowell Observatory in Flagstaff, Arizona, Tombaughs task was to search among millions o
13、f stars for a moving point of light, a planet that the observatorys founder thought existed beyond the orbit of Neptune. After years efforts, Tombaugh finally found it. Pluto was the first planet discovered by an American, and represented a moment of light in the darkness of the Great Depression. Fo
14、r decades, Pluto thrived in its role as the ninth major planet of our solar system, even though it was tiny compared to the others and so far away. However, 62 years after its discovery, two astronomers discovered another planetlike object beyond the orbit of Neptune. Six months later, they discover
15、ed a third object. It looked like Pluto might actually be a member of a sort of asteroid 【 精品教育资源文库 】 belt, similar to but way beyond one weve known about for a long time between the orbits of Mars and Jupiter. Another 14 years passed, dozens more objects beyond Neptune like Pluto had been discover
16、ed, so the International Astronomical Union elected to degrade the planet. It now shares its dwarf planet designation with three of the 1,200 bodies that have been located beyond Neptune today, collectively known as “Kuiper Belt Objects” The Kuiper Belt is populated by icy bodies that are remnants o
17、f the solar systems formation. These are the building blocks of planets. We now also know the surface of Pluto contains ices composed of methane, nitrogen, and other compounds familiar to us. It also seems to have a bright polar cap, like on Earth. Its atmosphere is very thin, but its composed large
18、ly of nitrogen, like our own. So, as we finally get within 7,800 miles of Pluto today, we scientists are hoping we can finally understand how the chaos at the beginning of the solar system could have created objects so similar and yet so foreign as Earth and Pluto. Pluto is much more than something
19、that is not a planet. Its a reminder that there are many worlds out there beyond our own that the sky isnt the limit at all. We dont know what kinds of fantastic variations on a theme nature is capable of making until we get out there to look. 篇章导读：本文是一篇说明文，主要介绍了冥王星 从被发现到被降级的原因及经过。 5 Pluto was disco
20、vered by Clyde Tombaugh in _ . A 1930 B 1939 C 1992 D 2006 答案： A 细节理解题。由第一段中的 “Pluto which famously was degraded from a major planet in 2006” 以及第四段首句和第五段首句可知，向前推 76 年就是发现冥王星的时间： (2006 76 )1930 年。故答案选 A。 6 Now the official designation of Pluto is _ . A Asteroid Belt B Kuiper Belt C Major Planet D Dwa
21、rf Planet 答案： D 细节理解题。由第五段第二句 “It now shares its dwarf planet designation with three of the 1,200 bodies that have been located beyond Neptune today, collectively known as Kuiper Belt Objects ” 可知，现在冥王星的正式名称是矮行星。故答案选 D。 7 Pluto and Earth are to some extent similar for _ . A both of them are populate
22、d by icy bodies that are remnants of the solar systems formation 4.6 billion years ago B the atmosphere of either of them is mainly made up of nitrogen C there are ices throughout the surface of both D both of them have bright polar caps on the north pole as well as the south 【 精品教育资源文库 】 pole 答案：
23、B 推理判断题。由第六段最后一句 “Its atmosphere is very thin, but its composed largely of nitrogen, like our own.” 可推知，冥王星和地球在某种程度上具有相似之处，因为它们的大气层主要成分都是氮。故答案选 B。 8 Which of the following statements is TRUE? A There are nine major planets in the solar system. B There is an asteroid belt between the orbits of Mars and Jupiter. C Pluto now shares its designation with 1,200 bodies that have been located beyond Neptune. D Clyde Tombaugh discovered Pluto with the telescope out of spare auto parts, old equipment and selfground lense
