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 linethrough the centre. You may not use any of the words in the bank more

Most forms of steel 26 becomebrittle (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

Answer the questions by marking the corresponding letter on AnswerSheet 2.The future of personal satellite technology is hereare we ready for
12、 it?A Satellites used to be the exclusive playthings of rich governments and wealthycorporations. But increasingly, as space becomes more democratized, they are coming withinreach of ordinary people. Just like drones (无人机) before them, miniature satellites are beginningto fundamentally transform our
13、 conceptions of who gets to do what 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 drop
14、s sharply, the risks of irresponsibleuse 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 beneficia
15、ldevelopment and use of this technology actually look like? 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 ficti
16、on. But over the past few decades 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
17、-satellites can fit in a launch vehicles formerly “wasted space.” Multiplescan be deployed in combination for more complex missions than could be achieved by oneCubeSat alone.D Within their compact bodies these minute satellites are able to house sensors andcommunications receivers/transmitters that
18、 enable operators to study Earth 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 Statio
19、n (ISS) hang out. But they can attain-2 - more 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 orbitthan a traditional communications or G
20、PS satellite. For instance, a research group here at ArizonaState University recently claimed their developmental small CubeSats could cost as little as$3,000 to put in orbit. This decrease in cost a11ows researchers, hobbyists and even elementaryschool groups to put simple instruments into LEO or e
21、ven having them deployed from the ISS.F 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
22、evenBoeing have all launched and operated CubeSats. 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
23、not just for rocket scientists anymore.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 th

Yet as LEO opens upto more amateur satellites, they may pose
