2024年12月英語四級閱讀理解模擬:超導(dǎo)材料
2024年12月英語四級考試在即,同學(xué)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(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月英語四級作文預(yù)測:垃圾分類的意義
2024年12月英語四級考試將在12月14日早上舉行,同學(xué)們在考前要多練多背哦。今天學(xué)習的內(nèi)容是2024年12月英語四級作文預(yù)測:垃圾分類的意義,一起來看看吧。 2024年12月英語四級作文預(yù)測:垃圾分類的意義 The Significance of Garbage classification In the face of increasing garbage production and environmental deterioration, there is an urgent need for waste sorting. And the reasons why we need to classify garbage come as follow. To begin with, as is often said, garbage is a resource used in the wrong place. As long as the garbage is properly classified and recycled, it will not only reduce the amount of garbage,beautify the environment, ?but also reduce unexpected waste, maximize the use of resources. What’s more, reasonable garbage classification will reduce environmental pollution, because through garbage classification, harmful substances can be selected out, so as to prevent harmful substances from contaminating the soil and endangering the survival and growth of plants and animals. So we should pay attention to garbage classification, protecting the environment on which we live. 面對日益增多的垃圾和惡化的環(huán)境,垃圾分類的需求迫在眉睫。我們需要垃圾分類的原因如下。? 首先,正如人們常說的,垃圾是一種被用在錯誤的地方的資源。只要對垃圾進行適當?shù)姆诸惡突厥?,不僅可以減少垃圾的數(shù)量,美化環(huán)境,還可以減少意外的浪費,最大限度地利用資源。而且合理的垃圾分類可以減少對環(huán)境的污染,因為通過垃圾分類可以篩選出有害物質(zhì),從而防止有害物質(zhì)污染土壤,危及動植物的生存和生長。? 所以我們應(yīng)該注意垃圾分類,保護我們賴以生存的環(huán)境。

經(jīng)濟學(xué)術(shù)語:FER
FER 國際貿(mào)易中需要結(jié)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(mào)易順差和資本流入集中到本國央行內(nèi)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(yù)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(guān)于第二個問題,中方從來不刻意追求貿(mào)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(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月英語四級聽力提分技巧之長對話
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(nèi)容;二是根據(jù)對話的結(jié)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(yù)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(guān)鍵詞是 manual,出現(xiàn)的問題并非在于產(chǎn)品的質(zhì)量,而是缺少使用手冊,故C)為答案。 05 時間數(shù)字處 設(shè)題對話中出現(xiàn)年代、時間、價格等數(shù)字信息的地方,也經(jīng)

經(jīng)濟學(xué)術(shù)語:Happiness Index
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?!倍殬I(yè)經(jīng)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.
