CLI CLI（Cost of Living Index，生活費用指數(shù)）是指在不同時點，消費者為達(dá)到某一效用（或者福利、生活標(biāo)準(zhǔn)）水平所需要的最小支出之比。 生活費用指數(shù)理論認(rèn)為，消費者的行為是理性的，在價格發(fā)生變化的情況下，消費者會調(diào)整自己的消費行為和消費模式，達(dá)到消費行為的最優(yōu)化。 我們來看2個例句： Only Zips where the cost of living index was between 100 and 200 were considered.? 我們只考慮生活費指數(shù)在100和200之間的郵政區(qū)域。 His high cost of living index incurred a prosecutor's suspicion.? 他的高生活消費指數(shù)招致了一名檢察官的懷疑。 20節(jié)BEC初級、中級、高級課程 學(xué)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(xué) 2個月后考試是否能順利通過 一聽即知！ 0元試學(xué)BEC初級中級高級課程 點擊立即免費試學(xué)>> 點擊立即免費試學(xué)>>> 祝大家順利拿證

2024年12月英語四級考試在即，同學(xué)們要認(rèn)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

Unemployment Rate 社會人最關(guān)注的的經(jīng)濟指標(biāo)大概就是Unemployment Rate（失業(yè)率）了。 Unemployment Rat可以用來判斷一定時期內(nèi)全部勞動人口的就業(yè)情況。它可以適當(dāng)反應(yīng)經(jīng)濟發(fā)展，比如這幾年大環(huán)境不景氣，考公考研的人數(shù)明顯增多，2020年考研人數(shù)怒增50萬就是很明顯的例子。 我們來看2個例句： He said the unemployment rate remains "unacceptably high" and that faster growth is needed to replace jobs lost in the economic downturn. 他說，失業(yè)率之高依然“不可接受”，需要加快增長速度已彌補在經(jīng)濟下滑期間失去的工作崗位。 The U. K. unemployment rate, surprisingly, is only slightly above the German rate. 令人驚訝的是，英國的失業(yè)率只比德國高一點點。 20節(jié)BEC初級、中級、高級課程 學(xué)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(xué) 2個月后考試是否能順利通過 一聽即知！ 0元試學(xué)BEC初級中級高級課程 點擊立即免費試學(xué)>> 點擊立即免費試學(xué)>>> 祝大家順利拿證

RPI RPI（Retail Price Index，商品零售價格指數(shù)）是指反映一定時期內(nèi)商品零售價格變動趨勢和變動程度的相對數(shù)。 零售物價指數(shù)是編制財政計劃、價格計劃、制定物價政策、工資政策的重要依據(jù)。 目前我國商品零售價格指數(shù)采用加權(quán)算術(shù)平均公式計算，調(diào)查范圍涉及食品、飲料煙酒、服裝鞋帽、紡織品、家用電器及音像器材、文化辦公用品、日用品、體育娛樂用品、交通通信用品、家具、化妝品、金銀珠寶、中西藥品及醫(yī)療保健用品、書報雜志及電子出版物、燃料、建筑材料及五金電料等16大類商品。 我們來看2個例句： Interest on student loans is pegged to inflation, as measured by the RPI, in order to maintain the real value of the debt over its term.? 學(xué)生貸款利率與通貨膨脹率掛鉤，這由零售物價指數(shù)來衡量，以保持在借貸期內(nèi)債務(wù)的實際價值不變。 The state pension, also linked to the RPI, must go up by at least 2.5%, following a promise made by ministers a few years ago when inflation fell and pensioners got shirty. 幾年以前當(dāng)通貨膨脹下降并且退休人員憤怒的時候，部長們做出一項承諾，之后，與零售物價指數(shù)掛鉤的國家養(yǎng)老金至少上漲了2.5％。 20節(jié)BEC初級、中級、高級課程 學(xué)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(xué) 2個月后考試是否能順利通過 一聽即知！ 0元試學(xué)BEC初級中級高級課程 點擊立即免費試學(xué)>> 點擊立即免費試學(xué)>>> 祝大家順利拿證
