2、由于 2019 年 6 月六级考试全国共考了 2 套听力,本套真题听力与前 2 套内容完全一样,只是顺序不一样,因此在本套真题中不再重复出现。Part Reading Comprehension (40 minutes)Section ADirections: In this section, there is a passage with ten blanks. You are required to select one wordfor each blank from a list of choices given in a word bank following the passage.
3、 Read the passagethrough carefully before making your choices. Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2 with a single line throughthe centre. You may not use any of the words in the bank more than once.Questions 26 to 35 a

Most forms of steelbrittle (脆的) at temperatures below about -25 unless they are mixed with other metals. Now,though, a novel type of steel has been developed that resists 27 at much lower temperatures,w

12、usive playthings of rich governments and wealthy corporations.But increasingly, as space becomes more democratized, they are coming within reach of ordinarypeople. Just like drones (无人机) before them, miniature satellites are beginning to fundamentallytransform our conceptions of who gets to do what
13、up above our heads.B) As a recent report from the National Academy of Sciences highlights, these satellites holdtremendous potential for making satellite-based science more accessible than ever before.However, as the cost of getting your own satellite in orbit drops sharply, the risks of irresponsib
14、leuse grow. The question here is no longer “Can we?” but “Should we?” What are the potentialdownsides of having a slice of space densely populated by equipment built by people nottraditionally labeled as “professionals”? And what would the responsible and beneficialdevelopment and use of this techno

Some of the answers may come from anonprofit organization that has been building and launching amateur satellites for nearly 50 years.C) Having your personal satellite launched into orbit might sound like an idea straight out ofscience fiction. But over the past few decades
16、a unique class of satellites has been created that fitsthe bill: CubeSats. The “Cube” here simply refers to the satellites shape. The most commonCubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweighton your desk. These mini-satellites can fit in a launch ve

D) Within their compact bodies these minute satellites are able to house sensors andcommunications receivers/transmitters that enable operators to study Earth
18、 from space, as well asspace around Earth. Theyre primarily designed for Low Earth Orbit (LEO)an easily accessibleregion of space from around 200 to 800 miles above Earth, where human-tended missions like theHubble Space Telescope and the International Space Station (ISS) hang out. But they can atta
19、inmore distant orbits; NASA plans for most of its future Earth-escaping payloads (to the moon andMars especially) to carry CubeSats.E) Because theyre so small and light, it costs much less to get a CubeSat into Earths orbit than atraditional communications or GPS satellite. For instance, a research
20、group here at Arizona StateUniversity recently claimed their developmental small CubeSats could cost as little as $3,000 toput in orbit. This decrease in cost allows researchers, hobbyists and even elementary schoolgroups to put simple instruments into LEO or even having them deployed from the ISS.F
21、) The first CubeSat was created in the early 2000s, as a way of enabling Stanford graduatestudents to design, build, test and operate a spacecraft with similar capabilities to the USSRsSputnik (前苏联的人造卫星). Since then, NASA, the National Reconnaissance Office and evenBoeing have all launched and opera

There arc more than 130 currently in operation.The NASA Educational Launch of Nano Satellite program, which offers free launches foreducational groups and science missions, is now open to U.S. nonprofit corporations as well.Clearly, satellites are not just for rocket scientists anymore
23、.G) The National Academy of Sciences report emphasizes CubeSats importance in scientificdiscovery and the training of future space scientists and engineers. Yet it also acknowledges thatwidespread deployment of LEO CubeSats isnt risk-flee. The greatest concern the authors raise isspace debrispieces
