  • 2024年12月英語四級閱讀理解模擬:超導(dǎo)材料

    2024年12月英語四級考試在即,同學(xué)們要認真?zhèn)淇寂?。今天為大家?guī)淼氖?024年12月英語四級閱讀理解模擬:超導(dǎo)材料,一起來看看吧。 2024年12月英語四級閱讀理解模擬:超導(dǎo)材料 The stone age, The Iron Age. Entire epochs havebeen named for materials. So what to call thedecades ahead? The choice will be tough. Welcometo the age of superstuff. Material science -- once theleast sexy technology – is bursting with new, practical discoveries led by superconducting ceramicsthat may revolutionize electronics. Butsuperconductors are just part of the picture: from house and cars to cook pots and artificialteeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics willshape the future just as surely as have genetic engineering and computer science. The key to the new materials is researchers’ increasing ability to manipulate substances atthe molecular level. Ceramics, for example, have long been limited by their brittleness. Butby minimizing the microscopic imperfections that cause it, scientists are making far strongerceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. nowuses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissorsand knives that stay sharp for years and never rust or corrode. A similar transformation has overtaken plastics. High-strength polymers now formbridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricitywhen vibrated or pushed is used in electric guitars, touch sensors for robot hands and karatejackets that automatically record each punch and chop. Even plastic litter, which oncethreatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings forexample, gradually decompose when exposed to sunlight. Researchers are developing ways tomake plastics as recyclable as metal or glass. Besides, composites – plastic reinforced withfibers of graphite or other compounds – made the round-the-world flight of the voyagerpossible and have even been proved in combat: a helmet saved an infantryman’s life bydeflecting two bullets in the Grenada invasion. Some advanced materials are old standard with a new twist. The newest fiberoptic cablethat carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane. But new materials have no impact until they are made into products. And that transitioncould prove difficult, for switching requires lengthy research and investment. It can be said afirmer handle on how to move to commercialization will determine the success or failure of acountry in the near future. 1. How many new materials are mentioned in this passage? [A] Two [B] Three [C] Four [D] Five 2. Why does the author mention genetic engineering and computer science? [A] To compare them with the new materials. [B] To show the significance of the new materials on the future world. [C] To compare the new materials to them. [D] To explain his view point. 3. Why is transition difficult? [A] Because transition requires money and time. [B] Because many manufacturers are unwilling to change their equipment. [C] Because research on new materials is very difficult. [D]Because it takes 10 years. 4. Where lies success of a country in the New Age of superstuff? [A] It lies in research. [B] It lies in investment. [C] It lies in innovation. [D] It lies in application. Vocabulary 1. superstuff 超級材料 2. superconducting ceramic 超導(dǎo)陶瓷 3. exotic 神奇的 4. shape 塑造,成型 5. brittleness 脆性 6. polymer 聚合體 7. karate jacket 空手道外衣 8. touch sensor 觸及傳感器 9. each punch and chop 每一個擊、打 10. blot 玷污,損害風(fēng)景的東西 11. tinker 修補,調(diào)整 12. amendable 服從于,遵循的 13. biodegradable 能生物遞減分解的 14. six-pack rings 放六個罐子的環(huán)狀物 15. decompose 分解 16. recyclable 可

  • 經(jīng)濟學(xué)術(shù)語:Labor-intensive

    Labor-intensive Labor-intensive是指勞動密集型的,它是指單位勞動占用的資金數(shù)量較少,勞動消耗所占的比重較大的。在勞動的消耗中,也不僅指簡單的體力勞動,而且還包括復(fù)雜的、高級的、腦力的勞動消耗。 我們來看2個例句: Largely because China is not quite ready to dismantle labor-intensive industries that still provide much-needed jobs at home. 這很大程度上是因為中國沒有做好準備,放棄仍在提供急需的國內(nèi)就業(yè)崗位的勞動密集型產(chǎn)業(yè)。 Tourism

  • 備考雅思口語的四個方法

    下好印象 見到考官,一定不要不說話,需要主動與考官溝通。例如,在進入考場之前,考官會讓你把包放在門口,并要求你關(guān)閉移動設(shè)備。這時,你也可以主動說:“我已經(jīng)關(guān)機了?!边@些看似不重要的英語口語會為你占據(jù)一些主動權(quán)。 如果你遇到一位隨和健談的考官,可能會問你:“今天感覺怎么樣?”這時,不要說:“我真的很緊張,因為我的英語口語很糟糕?!倍歼€沒開始考試呢,就先否定自己的這種做法真的很不明智。即使你真的很緊張,也沒有必要誠實地說出你的真實感受。 3. 目光接觸 請注意,口試實際上是兩個人相互交流的過程。很多考生擔(dān)心自己會緊張,故意避免與考官眼神接觸。事實上,這是一個非常糟糕的表現(xiàn)。當跟別人說話時,必須看著對方的眼睛以示尊重。即使不是一直盯著考官看,也需要時不時地互相對視。 同時,如果完全不跟對方對視的話,考官是會認為你是在背答案,這樣一來分數(shù)一定不會高。 4. 肢體語言 口語考試的關(guān)鍵是交流,交流可以是一個輕松隨意的過程,坐在椅子上時不必太拘謹。一些必要的肢體語言會給考官一個加分的印象,這樣自己就能表現(xiàn)出良好的溝通能力和自信。相信考官會更喜歡和一個自然、流利、自信的學(xué)生交談。 以上就是小編給大家分享的雅思口語考試方法,希望可以給大家學(xué)習(xí)帶來幫助。 王總早上好,請問一下中標通知書是登錄系統(tǒng)查詢嗎,因為我剛剛看了上面的“中標結(jié)果通知”還是顯示灰色

Manchester Art Gallery has recruited two of the country's leading experts in stress management to choose pictures that are guaranteed to leave even the most frantic feeling at ease wich the world.They have created the "tranquility tour" which allows city-centre workers to spend their lunch hour taking a soothing tourof what are described as "some of the most relaxing and inspiring paintings ever committed to canvas”. The free tour takes the visitor through several centuries of painting, from the Victorian aesthetic h the PreRaphaelite school, to modern abstract an.   Kim Gowland, a gallery executive. said: "Looking at art is a stress-relieving activity. What we are tryingto do is encourage people who work in the city to spend half an hour of their lunchbreak in the gallery. to chill out rather than rush around the shops."   The five works chosen by Andrew Loukes. the gallery's manager, are: John Roddam Spencer Stanhope’s The Waters of Lethe (1880), Turner's Thomson’s Aeolian Harp (1809), Sir John Everett Millais’s Autumn Leaves (1856), James Durden’s Summer in Cumberland (1925) and Bridget Riley’s Zephyr (1976).   Mr. Loukes said: "We chose five pictures that suggest restfulness. We also wamed to display the breadth of the collection. We arc particularly strong in early-19th and early-20th-century British art."   Their therapeutic powers have been endorsed by Olga Gregson and Terry Looker from the Department of Biological Sciences at Manchester Metropolitan University. Dr. Gregson said that "research shows that stress levels have reduced and moods changed for the better” when subjects looked at paintings.   "Although art appreciation is very much a matter of personal choice, it is true that some works of art appeal to almost everyone, and that some paintings have qualities that can induce relaxation in most people."Dr. Gregson said. "Great painters such as Leonardo da Vinci were masters of techniques that could evoke particular responses in the viewer."   Dr. Gregson said the gallery represented an "oasis of calm".
