FER 國際貿易中需要結算，所以我們需要有外國的貨幣，這就是FER（Foreign Exchange Reserve，外匯儲備）。 貿易順差和資本流入集中到本國央行內就形成外匯儲備。FER主要用于清償國際收支逆差，以及當本國貨幣被大量拋售時，利用外匯儲備買入本國貨幣干預外匯市場，以維持該國貨幣的匯率。 我們來看2個例句： The continuous increase of the foreign exchange reserve has guaranteed RMB to be in the further consolidated position. 外匯儲備的不斷增加確保了人民幣地位的進一步鞏固。 On your second question, China never intends to seek for a trade surplus nor the increase of foreign exchange reserve. 關于第二個問題，中方從來不刻意追求貿易順差，也不刻意追求外匯儲備的增長。 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~ ?

Gini Index Gini Index（基尼系數(shù)）是國際上通用的衡量一個國家或地區(qū)居民收入差距的常用指標。 基尼系數(shù)最一大為“1”，最小等于“0”?；嵯禂?shù)越接近0表明收入分配越是趨向平等。 國際慣例把0.2以下視為收入絕對平均， 0.2-0.3視為收入比較平均； 0.3-0.4視為收入相對合理； 0.4-0.5視為收入差距較大， 當基尼系數(shù)達到0.5以上時，則表示收入懸殊。 我們來看2個例句： He said 40 percent on the Gini index is already too risky and China's Gini index is close to 50 percent. 他說，基尼指數(shù)40%就已經相當危險了，而中國的基尼指數(shù)將近是50%。 Because of high GDP per capita, welfare benefits, a low Gini index, and political stability, the Danish enjoys high living standards topped by no other nation.? 由于其高人均GDP，良好的福利，較低的基尼系數(shù)和穩(wěn)定的政治，丹麥是世界上生活水平最高的國家。 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

RPI RPI（Retail Price Index，商品零售價格指數(shù)）是指反映一定時期內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)采用加權算術平均公式計算，調查范圍涉及食品、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，以保持在借貸期內債務的實際價值不變。 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

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

Happiness Index Happiness Index是幸福指數(shù)的意思，它是衡量人們對自身生存和發(fā)展狀況的感受和體驗，即人們的幸福感的一種指數(shù)。 不同的人對幸福感的理解和詮釋不同，比如市民小王說：“幸福就是工資再高一點。”而職業(yè)經理人胡明鑫認為：“最幸福的事情就是我要把公司做成一個世界品牌。” 我們來看2個例句： Undeterred, Prime Minister David Cameron has decided to create a national happiness index providing quarterly measures of how folks feel.

解題的根據(jù)主要有四點：一是根據(jù)對話的開頭判斷該對話的主要內容；二是根據(jù)對話的結尾判斷對話的主題；三是根據(jù)對話中多次出現(xiàn)的主要信息做合理的判斷；四是通過預覽選項進行合理的推理排除。 例4：What problem are the speakers discussing? A) The man has sent the order to the woman by mistake.B) Some of the telephone systems don’t work properly.C) Some of the packs do not contain any manuals.D) The quality of the goods is not up to the standard. 原文：W: What can I do for you? M: Well, unfortunately, there is a problem with the order we received from you yesterday. It seems we’ve not received the right quantity of manuals to support the telephone system. W: Oh, dear, that’s bad news. I’m very sorry to hear that, and you don’t know how many packs are without manuals? M: No, because we haven’t opened every pack. But in several of those that have been opened there are none. No manuals. 答案：C)。本題的關鍵詞是 manual，出現(xiàn)的問題并非在于產品的質量，而是缺少使用手冊，故C）為答案。 05 時間數(shù)字處 設題對話中出現(xiàn)年代、時間、價格等數(shù)字信息的地方，也經
