    2024年12月英語四級考試在即,同學們要認真?zhèn)淇寂丁=裉鞛榇蠹規(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模擬:大學專業(yè)選擇

    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:大學專業(yè)選擇,一起來看看吧。 2024年12月英語四級閱讀理解模擬:大學專業(yè)選擇 One of the bitterest and most time-worm debates in student union bars up and down the country is resolved as academic research confirms that in financial terms at least, arts degrees are a complete waste of time.Getting through university boosts students’earnings by 25%, on a weighted average, or $220,000 over theirlifetime, according to Professor Ian Walker of Warwick University-but if they study Shakespeare or the peasants’revolt instead of anatomy of contract law, those gains are likely to be completely wiped out. The government is about to allow universities to charge students up to $3,000 a year for their degrees, arguing that it’s a small price to pay compared with the financial rewards graduates reap later in life. But Prof. Walker’s research shows there are sharp variations in returns according to which subject a student takes. Law, medicine and economics or business are the most lucrative choices, making their average earnings 25% higher, according to the article, published in the office for national statistics’monthly journal. Scientists get 10-15% extra. At the bottom of the list are arts subjects, which make only a “small ”differenceto earnings- a small negative one, in fact. Just ahead are degrees in education-which leave hard pressed teachers anaverage of 5% better off a year than if they had left school at 18. “it’s hard to resist the conclusion that what students learn does matter a lot; and some subject areas givemore modest financial returns than others,” Prof. Walker said. As an economist, he was quick to point outthat students might gain non-financial returns from arts degrees:”Studying economics might be very dull, forexample, and studying post-modernism might be a lot of fun.” 練習題: Choose correct answers to the question: 1.What is the best title for the passage? A.Professor Walker’s Research B.How to Make Big Money. C.Differences Between Science and Arts Degrees. D.Studying Arts Has Negative Financial Outcome. 2.Universities charge students a rather high tuition mainly because_____ provide the students with very prosperous subjects to learn assume that their graduates can earn much more than they had paid don’t get financial support from the government need much revenue to support the educational expenses 3.The word “l(fā)ucrative”(Line 1, Para. 4) most probably means _____ le ve able le 4.Law, medical and business graduates could earn 25% more than ______ ion graduates graduates who had not studied at the university average income 5.We can safely conclude that the author ______ s arts degrees as meaningless this result disappointing and unfair the students to think twice before they decide what to learn in college that arts degrees are still rewarding despite its scarce financial returns 參考答案: 1.[D] 主旨大意題。本文為Walker教授的研究成果,旨在說明不同專業(yè)的畢業(yè)生有不同的經(jīng)濟回報,并非要傳授發(fā)財心得或者比較文理科的異同。文章首句即為本題解題關鍵,故D正確。 2.[B] 事實細節(jié)題。定位至第3段第1句。本文只有這一句與收取學費有關,后一個分句即前一個分句的理由,抓住其中隱含的因果關系就不難找到正確答案。 3.[C] 詞義理解題。通過下文數(shù)據(jù)earnings 25% higher和get 10-15% extra可以推測lucrative大意應為“給人帶來豐厚收入的”,故選C。 4.[C] 事實細節(jié)題。第4段中出現(xiàn)了幾個比較數(shù)字,考題要求找到此段首句提到的收人增加25%的參照點。第2段第1句中的Getting through university 表明這類學生收人增加25%的參照對象是沒讀大學的人,且從第4段第3句中的the list和第4句即可以確定這一段是在比較大學畢業(yè)與18歲畢業(yè)(即沒讀大學)收入的不同,因此C正確。 5.[D] 推理判斷題。結(jié)論往往出現(xiàn)在文章結(jié)尾,要想答對此題,一定要仔細體會本文末句。本文雖然重點討論文科沒有經(jīng)濟效益,但是作者并沒有做出主觀判斷,故A、B、C都不正確,而作者在文章最后講到了人文學科雖然經(jīng)濟效益不佳但學習過程更有趣,故D符合作者意思。 以上就是關于“2024年12月英語四級閱讀理解模擬:大學專業(yè)選擇”的全部內(nèi)容啦,祝同學們考試順利。

    沒寫,只有你寫了,哪怕你翻譯的有很多錯誤,你也可以拿到滿分。 當然,這種情況幾乎不可能出現(xiàn)。 把710分的滿分看成100分,各題型的分值分別如下: ?聽力部分為35分: 前15題每題1分,后10道題每題2分。 ?閱讀部分為35分: 選詞填空每題0.5分,總計5分; 信息匹配題每題1分,總計10分; 仔細閱讀每題2分,總計20分。 ?寫作部分15分。 ?翻譯部分15分。 用這個方法計算,根據(jù)往年的經(jīng)驗: ??四級一般能考到55分基本就穩(wěn)過四級425分; ??六級一般考到57分,通過六級425分的概率很大。 寫作和翻譯,無法估計具體的分數(shù),但我們也可以算個大概。 自己先看看作文和翻譯的范文,然后對比自己的寫的: ◎如果整體沒什么錯誤,11-13分; ◎如果有個別小錯誤,8-10分; ◎如果錯誤很多,5-7分 ◎如果完全跑題,4分及以下。 大家可以按照上面這個方法,去對對答案,然后計算一下自己的成績哦~

  • 經(jīng)濟學職場術語:PPP

    PPP 如果對不同國家的GDP進行比較呢,一個方法就是PPP(Purchasing Power Parity,購買力平價)。 購買力平價是根據(jù)各國不同的價格水平計算出來的貨幣之間的等值系數(shù),如果一個巨無霸在美國的價格是4美元,而在國是3英鎊,那么美元與英鎊的購買力平價匯率就是3英鎊=4美元。 我們來看2個例句: PPP measures show where currencies should end up in the long run. 購買力平價方法顯示出貨幣從長遠來看的價格。 For this reason, PPP is a more reliable comparison for the currencies of economies with similar levels of income. 由于這樣的原因,購買力平價方法在比較有相近收入水平的經(jīng)濟體時更為可靠。 20節(jié)BEC初級、中級、高級課程 學前測試、詞匯課、各級別專項課 還有考前沖刺 點擊立即免費聽>> 你適合考哪個級別?BEC好不好學 2個月后考試是否能順利通過 一聽即知! 0元試學BEC初級中級高級課程 點擊立即免費試學>> 點擊立即免費試學>>> 祝大家順利拿證~

    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
