1、溫故而知新，下筆如有神。 近2年英語六級專題測練習(xí)及答案第3套 Part I Writing (30 minutes) Directions:?For this part, you are allowed 30 minutes to write an essay on the importance of motivation and methods in learning. You should write at least 150 words but no more than 200 words. _______________________________________

2、_________________________________ ________________________________________________________________________ ________________________________________________________________________ Part Ⅰ Writing The Importance of Motivation and Methods in Learning When it comes to learning, there is a famous Ch

3、inese saying which goes "Learning without thinking leads to confusion; thinking without learning ends in danger." Evidently, it is meant to tell us that learning methods are as important as hard work. I totally agree with it. Besides, I insist that in addition to diligence and methods, motivation in

4、 learning should also be paid attention to. As for me, motivation is an indispensable part of learning, because without motivation, you won't start to learn at all. Even if you have started studying, without motivation that drives you to keep going, you may easily give up when faced with difficulti

5、es. With motivation, we also need the right way to learn. In the learning process, hard work is not enough. If we don't attach importance to learning methods, we may fall into the dilemma of studying mechanically. Instead, with effective learning methods, there will be twice the result with half th

6、e effort. In brief, motivation and methods are critical to successful learning. Therefore, only when we are clearly aware of this, can we achieve good learning results by making efforts. Part II Listening Comprehension (30 minutes) 說明：由于近2年年6月六級考試全國共考了兩套聽力，本套專題測練習(xí)聽力與前2套內(nèi)容相同，只是選項(xiàng)順序不同，因此在本套專題測練習(xí)中

7、不再重復(fù)出現(xiàn)。 Part III Reading Comprehension (40 minutes) Section A Directions:?In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making you

8、r 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 through the centre. You may not use any of the words in the bank more than once. Steel（鋼鐵） is valued for its reliability可靠性, but not when it gets col

9、d. Most forms of steel _A_26_abruptly突然地、硬生生的_ become brittle （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對抗、抵抗 _J_27_fractures破碎、碎裂_ at much lower temperatures, while retaining保留、留住 its strength and

10、toughness韌性、韌度—without the need for expensive _B_28_additives(添加劑）_. Steel's fragility at low temperatures first became a major concern during the Second World War. After German U-boats torpedoed （用魚雷攻擊）numerous British ships, a 2,700-strong fleet of cheap- and-cheerful "Liberty ships" was introduc

11、ed to replace the lost vessels, providing a lifeline for the _E_29_besieged（被包圍）_ British. But the steel shells of hundreds of the ships _I_30_cracked（破裂）_ in the icy north Atlantic, and 12 broke in half and sank. Brittleness（脆弱、脆性） remains a problem when building steel structures in cold condition

12、s, such as oil rigs in the Arctic. So scientists have _N_31_strived（努力、奮斗）_ to find a solution by mixing it with expensive metals（金屬、五金） such as nickel（鎳）. Yuuji Kimura and colleagues in Japan tried a more physical（物理的、物質(zhì)的、符合自然法則的） _C_32_approach（方法）_. Rather than adding other metals, they develope

13、d a complex mechanical （機(jī)械、力學(xué)）process involving repeated heating（加熱、采暖） and very severe（嚴(yán)重、嚴(yán)厲、嚴(yán)格） mechanical deformation（變形）, known as tempforming. The resulting steel appears to achieve a combination of strength（強(qiáng)度） and toughness（韌性） that is _G_33_comparable（想當(dāng)、可比）_ to that of modem steels that ar

14、e very rich in alloy（合金） content（內(nèi)容、含量、目錄） and, therefore, very expensive. Kimura's team intends（打算） to use its tempformed steel to make ultra-high（超高） strength parts, such as bolts（螺栓、鉚釘）. They hope to reduce both the number of _H_34_components（組建、部件）_ needed in a construction job and their weight

15、—by（按……計(jì)算） replacing solid（實(shí)心的、實(shí)體的） supports with _K_35_hollow（空心的）_ tubes（管）, for example. This could reduce the amount of steel needed to make everything from automobiles（發(fā)動機(jī)） to buildings and bridges（橋梁）.

17、 the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. The future of personal satellite（衛(wèi)星） technology is here—are we ready for it? A）Satellites used to be the exclu

18、sive playthings of rich governments and wealthy corporations. But increasingly, as space becomes more democratized, they are coming within reach of ordinary people. Just like drones （無人機(jī)）before them, miniature satellites are beginning to fundamentally transform our conceptions of who gets to do what

19、 up above our heads. B）As a recent report from the National Academy of Sciences highlights, these satellites hold tremendous 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 irrespo

20、nsible use grow. The question here is no longer "Can we?" but "Should we?" What are the potential downsides of having a slice of space densely populated by equipment built by people not traditionally labeled as "professionals" ? And what would the responsible and beneficial development and use of th

21、is technology actually look like? Some of the answers may come from a nonprofit 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 of science fiction. But over the past

22、few decades a unique class of satellites has been created that fits the bill: CubeSats. The "Cube" here simply refers to the satellite's shape. The most common CubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk. These mini-satellites can fi

23、t in a launch vehicle's formerly "wasted space. " Multiples can be deployed in combination for more complex missions than could be achieved by one CubeSat alone. D）Within their compact bodies these minute satellites are able to house sensors and communications receivers/transmitters that enable ope

24、rators to study Earth from space, as well as space around Earth. They're primarily designed for Low Earth Orbit （LEO）—an easily accessible region of space from around 200 to 800 miles above Earth, where human-tended missions like the Hubble Space Telescope and the International Space Station （ISS） h

25、ang out. But they can attain more distant orbits; NASA plans for most of its future Earth-escaping payloads （to the moon and Mars especially） to carry CubeSats. E）Because they're so small and light, it costs much less to get a CubSat into Earth's orbit than a traditional communications or GPS satel

26、lite. For instance,a research group here at Arizona State University recently claimed their developmental small CubeSats could cost as little as $3,000 to put in orbit. This decrease in cost allows researchers, hobbyists and even elementary school groups to put simple instruments into LEO or even ha

27、ving them deployed from the ISS. F）The first CubeSat was created in the early 2000s,as a way of enabling Stanford graduate students to design, build, test and operate a spacecraft with similar capabilities to the USSR's Sputnik （前蘇聯(lián)的人造衛(wèi)星）.Since then, NASA, the National Reconnaissance Office and eve

28、n Boeing have all launched and operated CubeSats. There are more than 130 currently in operation. The NASA Educational Launch of Nano Satellite program, which offers free launches for educational groups and science missions, is now open to U. S. nonprofit corporations as well. Clearly, satellites ar

29、e not just for rocket scientists anymore. G）The National Academy of Sciences report emphasizes CubeSats' importance in scientific discovery and the training of future space scientists and engineers. Yet it also acknowledges that widespread deployment of LEO CubeSats isn't risk-free. The greatest co

30、ncern the authors raise is space debris—pieces of "junk" that orbit the earth, with the potential to cause serious damage if they collide with operational units, including the ISS. H）Currently, there aren't many CubeSats and they're tracked closely. Yet as LEO opens up to more amateur satellites, t

31、hey may pose an increasing threat. As the report authors point out, even near-misses might lead to the "creation of a burdensome regulatory framework and affect the future disposition of science CubeSats." I）CubeSat researchers suggest that now's the time to ponder unexpected and unintended possibl

32、e consequences of more people than ever having access to their own small slice of space. In an era when you can simply buy a CubeSat kit off the shelf, how can we trust the satellites over our heads were developed with good intentions by people who knew what they were doing? Some "expert amateurs" i

33、n the satellite game could provide some inspiration for how to proceed responsibly. J）In 1969.the Radio Amateur Satellite Corporation （AMSAT） was created in order to foster ham radio enthusiasts' （業(yè)余無線電愛好者）participation in space research and communication. It continued the efforts, begun in 1961, b

34、y Project OSCAR—a U. S. -based group that built and launched the very first nongovernmental satellite just four years after Sputnik. As an organization of volunteers, AMSAT was putting "amateur" satellites in orbit decades before the current CubeSat craze. And over time, its members have learned a t

35、hing or two about responsibility. Here, open-source development has been a central principle. Within the organization, AMSAT has a philosophy of open sourcing everything—making technical data on all aspects of their satellites fully available to everyone in the organization, and when possible, the p

36、ublic. According to a member of the team responsible for FOX 1-A, AMSAT's first CubeSat, this means that there's no way to sneak something like explosives or an energy emitter into an amateur satellite when everyone has access to the designs and implementation. K）However, they're more cautious abou

37、t sharing information with nonmembers, as the organization guards against others developing the ability to hijack and take control of their satellites. This form of "self-governance" is possible within long-standing amateur organizations that, over time, are able to build a sense of responsibility t

38、o community members,as well as society in general. But what happens when new players emerge, who don't have deep roots within the existing culture? L）Hobbyists and students are gaining access to technologies without being part of a long-standing amateur establishment. They're still constrained by f

39、imders, launch providers and a series of regulations—all of which rein in what CubeSat developers can and cannot do. But there's a danger they're ill-equipped to think through potential unintended consequences. What these unintended consequences might be is admittedly far from clear. Yet we know inn

40、ovators can be remarkably creative with taking technologies in unexpected directions. Think of something as seemingly benign as the cellphone—we have microfinance and text-based social networking at one end of the spectrum, and improvised （臨時制作的）explosive devices at the other. M）This is where a cul

41、ture of social responsibility around CubeSats becomes important-not simply to ensure that physical risks are minimized, but to engage with a much larger community in anticipating and managing less obvious consequences of the technology. This is not an easy task. Yet the evidence from AMSAT and other

42、 areas of technology development suggests that responsible amateur communities can and do emerge around novel technologies. The challenge here, of course, is ensuring that what an amateur community considers to be responsible, actually is. Here's where there needs to be a much wider public conversat

43、ion that extends beyond government agencies and scientific communities to include students, hobbyists，and anyone who may potentially stand to be affected by the use of CubeSat technology. 36. Given the easier accessibility to space, it is time to think about how to prevent misuse of satellites.I 3

44、7. A group of mini-satellites can work together to accomplish more complex tasks.C 38. The greater accessibility of mini-satellites increases the risks of their irresponsible use.B 39. Even school pupils can have their CubeSats put in orbit owing to the lowered launching cost.E 40. is careful abo

45、ut sharing information with outsiders to prevent hijacking of their satellites.K 41. NASA offers to launch CubeSats free of charge for educational and research purposes.F 42. Even with constraints, it is possible for some creative developers to take the CubeSat technology in directions that result

46、 in harmful outcomes.L 43. While making significant contributions to space science, CubeSats may pose hazards to other space vehicles.G 44. Mini-satellites enable operators to study Earth from LEO and space around it.D 45. AMSAT operates on the principle of having all its technical data accessibl

47、e to its members, preventing the abuse of amateur satellites.J Section C Directions:?There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and

48、 mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 46 to 50 are based on the following passage. When I re-entered the full-time workforce a few years ago after a decade of solitary self-employment, there was one thing I was looking forwar

49、d to the most: the opportunity to have work friends once again. It wasn't until I entered the corporate world that I realized, for me at least, being friends with colleagues didn't emerge as a priority at all. This is surprising when you consider the prevailing emphasis by scholars and trainers and

50、managers on the importance of cultivating close interpersonal relationships at work. So much research has explored the way in which collegial （同事的）ties can help overcome a range of workplace issues affecting productivity and the quality of work output such as team-based conflict, jealousy, undermini

51、ng, anger, and more. Perhaps my expectations of lunches, water-cooler gossip and caring, deep-and-meaningful conversations were a legacy of the last time I was in that kind of office environment. Whereas now, as I near the end of my fourth decade, I realize work can be fully functional and entirely

52、 fulfilling without needing to be best mates with the people sitting next to you. In an academic analysis just published in the profoundly-respected Journal of Management, researchers have looked at the concept of "indifferent relationships". It's a simple term that encapsulates （概括） the fact that

53、relationships at work can reasonably be non-intimate, inconsequential, unimportant and even, dare I say it, disposable or substitutable. Indifferent relationships are neither positive nor negative. The limited research conducted thus far indicates they're especially dominant among those who value i

54、ndependence over cooperation, and harmony over confrontation. Indifference is also the preferred option among those who are socially lazy. Maintaining relationships over the long term takes effort. For some of us, too much effort . As noted above, indifferent relationships may not always be the mos

55、t helpful approach in resolving some of the issues that pop up at work. But there are nonetheless several empirically proven benefits. One of those is efficiency. Less time chatting and socializing means more time working and（產(chǎn)出）. The other is self-esteem. As human beings, we're primed to compare o

56、urselves to each other in what is an anxiety-inducing phenomenon. Apparently, we look down on acquaintances more so than Mends. Since the former is most common among those inclined towards indifferent relationships, their predominance can bolster individuals' sense of self-worth. Ego aside, a third

57、 advantage is that the emotional neutrality of indifferent relationships has been found to enhance critical evaluation, to strengthen one's focus on task resolution, and to gain greater access to valuable information. None of that might be as fun as after-work socializing but, hey, I'll take it anyw

58、ay. 46. What did the author realize when he re-entered the corporate(企業(yè)) world? A） Making new Mends with his workmates was not as easy as he had anticipated. B） Cultivating positive interpersonal relationships helped him expel solitary feelings. C） Working in the corporate world requires more in

59、terpersonal skills than self-employment. D） Building close relationships with his colleagues(同事 was not as important as he had ejected（驅(qū)逐）. 47. What do we learn from many studies about collegial（大學(xué)的、社團(tuán)的） relationships? A） Inharmonious（不和諧、不和睦） relationships have an adverse（不利的、相反的） effect on prod

60、uctivity（生產(chǎn)力、生產(chǎn)率、生產(chǎn)能力）. B） Harmonious relationships are what many companies aim to cultivate. C） Close collegial relationships contribute very little to product quality. D） Conflicting relationships in the workplace exist almost everywhere. 48. What can be inferred about relationships at work fr

61、om an academic analysis? A） They should be cultivated. B） They are virtually（實(shí)際上、事實(shí)上、幾乎） irrelevant（不相干的）. C） They are vital to corporate culture. D） They should be reasonably intimate. 49. What does the author say about people who are socially lazy? A） They feel uncomfortable when engaging in

62、 social interactions. B） They often find themselves in confrontation with their colleagues. C） They are unwilling to make efforts to maintain workplace（工作場所） relationships. D） They lack basic communication skills in dealing with interpersonal issues. 60. What is one of the benefits of indifferen

63、t（冷漠的、中立的） relationships? A） They provide fun at work. B） They help control emotions. C） They help resolve differences. D） They improve work efficiency（效率、效益）. Passage Two Questions 51 to 55 are based on the following passage. In a few decades, artificial intelligence (AI) will surpass many o

64、f the abilities that we believe make us special. This is a grand challenge for our age and it may require an "irrational" response. One of the most significant pieces of news from the US in early 2017 was the efforts of Google to make autonomous driving a reality. According to a report, Google's se

65、lf-driving cars clocked 1,023,330 km, and required human intervention 124 times. That is one intervention about every 8,047 km of autonomous driving. But even more impressive is the progress in just a single year: human interventions fell from 0.8 times per thousand miles to 0.2, a 400% improvement.

66、 With such progress, Google's cars will easily surpass my own driving ability later this year. Driving once seemed to be a very human skill. But we said that about chess, too. Then a computer beat the human world champion, repeatedly. The board game Go（圍棋）took over from chess as a new test for human thinking in 2016, when a computer beat one of the world's leading professional Go players. With computers conquering what used to be deeply human tasks, what will it mean in the future to be human?
