    2024年12月英語四級考試在即,同學們要認真?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:超導材料,一起來看看吧。 2024年12月英語四級閱讀理解模擬:超導材料 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

  • 2024年12月英語四級閱讀理解擬:電視有害

    理了2024年12月英語四級閱讀理解模擬:電視有害,一起來看看吧。 2024年12月英語四級閱讀理解模擬:電視有害 Yes, but what did we use to do before there wastelevision? How often we hear statements like this! Television hasn't been with us all that long, but weare already beginning to forget what the world was like without it. Before we admitted the one-eyed monster into our homes, we never fond it difficult to occupy our spare time. We used toenjoy civilized pleasures. For instance, we used to have hobbies, we used to entertain ourfriends and be entertained by them, we used to go outside for our amusements to theatres, cinemas, restaurants and sporting events. We even used to read books and listen to music andbroadcast talks occasionally. All that belongs to the past. Now all our free time is regulatedby the goggle box. We rush home or gulp down our meals to be in time for this or thatprogramme. We have even given up sitting at table and having a leisurely evening meal, exchanging the news of the day. A sandwich and a glass of beer will do anything, providing itdoesn't interfere with the programme. The monster demands and obtains absolute silenceand attention. If any member of the family dares to open his mouth during a programme, he isquickly silenced. Whole generations are growing up addicted to the telly. Food is left uneaten, homeworkundone and sleep is lost. The telly is a universal pacifier. It is now standard practice formother to keep the children quiet by putting them in the living-room and turning on the set. Itdoesn't matter that the children will watch rubbishy commercials or spectacles of sadism andviolence so long as they are quiet. There is a limit to the amount of creative talent available in the world. Every day, television consumes vast quantities of creative work. That is why most of the programmes areso bad: it is impossible to keep pace with the demand and maintain high standards as well. When millions watch the same programmes, the whole world becomes a village, and society isreduced to the conditions which obtain in preliterate communities. We become utterlydependent on the two most primitive media of communication: pictures and the spokenword. Television encourages passive enjoyment. We become content with second-handexperiences. It is so easy to sit in our armchairs watching others working. Little by little, television cuts us off from the real world. We get so lazy, we choose to spend a fine day insemi-darkness, glued to our sets, rather than go out into the world itself. Television may be ssplendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to real living when we spend aholiday by the sea or in the mountains, far away from civilization. In quiet, naturalsurroundings, we quickly discover how little we miss the hypnotic tyranny of King Telly. 1. What is the biggest harm of TV? [A] It deprives people of communication with the real world. [B] People become lazy. [C] People become dependent on second-hand experience. [D] TV consumes a large part of one's life. 2. In what way can people forget TV? [A] Far away from civilization. [B] To a mountain. [C] By the sea. [D] In quiet natural surroundings. 3. What does a mother usually do to keep her children quiet? [A] Let them watch the set. [B] Put them in the living room. [C] Let them watch the rubbish. [D] Let them alone. 4. What does the first sentence in the first paragraph mean? [A] We found it difficult to occupy our spare time. [B] We become addicted to TV. [C] What we used to do is different from now. [D] We used to enjoy civilized pleasures. Vocabulary 1. goggle 轉(zhuǎn)動眼珠,瞪眼 goggle box (英俚)電視機 2. gulp 狼吞虎咽 3. telly 電視機 4. pacifier 平息者,撫慰者。這里指平靜人,使人不吱聲的東西。 5. rubbishy 垃圾的,無價值的 6. sadism 施淫虐 7. glue 膠(水);粘牢 glue to the sets 和電視機粘在一起,指成了電視迷 8. hypnotic 催眠的 寫作方法與文章大意 這是一篇論說“電視有害”的文章。采用對比分析手法。先提出問題,對比過去和現(xiàn)在“過去在業(yè)余時間,我們享受文明的歡樂,有各種嗜好,招待朋友,訪友,外出娛樂,在家讀書聽音樂……現(xiàn)在一切受

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.

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". "You have got this wonderful opportunity to evoke a different kind of psychophysiological response."   1. What is done by the Manchester Art Gallery is intended to____________.   A) find out the relation between paintings and stress-easing   B) promote its magnificent collection of British art   C) reduce working people's stress levels by art appreciation   D) provide an alternative of pastime for consumers   2.
