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.

    理了2024年12月英語(yǔ)六級(jí)閱讀理解模擬真題:大學(xué)專(zhuān)業(yè)選擇,一起來(lái)看看吧。 2024年12月英語(yǔ)六級(jí)閱讀理解模擬真題:大學(xué)專(zhuān)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(xí)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   1.[D]?主旨大意題。本文為Walker教授的研究成果,旨在說(shuō)明不同專(zhuān)業(yè)的畢業(yè)生有不同的經(jīng)濟(jì)回報(bào),并非要傳授發(fā)財(cái)心得或者比較文理科的異同。文章首句即為本題解題關(guān)鍵,故D正確。   2.[B]?事實(shí)細(xì)節(jié)題。定位至第3段第1句。本文只有這一句與收取學(xué)費(fèi)有關(guān),后一個(gè)分句即前一個(gè)分句的理由,抓住其中隱含的因果關(guān)系就不難找到正確答案。   3.[C]?詞義理解題。通過(guò)下文數(shù)據(jù)earnings 25% higher和get 10-15% extra可以推測(cè)lucrative大意應(yīng)為“給人帶來(lái)豐厚收入的”,故選C。   4.[C]?事實(shí)細(xì)節(jié)題。第4段中出現(xiàn)了幾個(gè)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(diǎn)。第2段第1句中的Getting through university 表明這類(lèi)學(xué)生收人增加25%的參照對(duì)象是沒(méi)讀大學(xué)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(xué)畢業(yè)與18歲畢業(yè)(即沒(méi)讀大學(xué))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(duì)此題,一定要仔細(xì)體會(huì)本文末句。本文雖然重點(diǎn)討論文科沒(méi)有經(jīng)濟(jì)效益,但是作者并沒(méi)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(xué)科雖然經(jīng)濟(jì)效益不佳但學(xué)習(xí)過(guò)程更有趣,故D符合作者意思。
