2024年12月英語(yǔ)四級(jí)閱讀理解模擬:超導(dǎo)材料
2024年12月英語(yǔ)四級(jí)考試在即,同學(xué)們要認(rèn)真?zhèn)淇寂?。今天為大家?guī)?lái)的是2024年12月英語(yǔ)四級(jí)閱讀理解模擬:超導(dǎo)材料,一起來(lái)看看吧。 2024年12月英語(yǔ)四級(jí)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(jí)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(gè)擊、打 10. blot 玷污,損害風(fēng)景的東西 11. tinker 修補(bǔ),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(gè)罐子的環(huán)狀物 15. decompose 分解 16. recyclable 可

學(xué)上一文段的題目還沒(méi)做完,下一段聽(tīng)力就開(kāi)始了,原因就在于不會(huì)配置時(shí)間,沒(méi)有經(jīng)過(guò)多次完整的聽(tīng)力訓(xùn)練。 如果剛開(kāi)始不能完整完成整個(gè)聽(tīng)力部分,可以采取分Section練習(xí)的形式,先適應(yīng)每個(gè)部分的聽(tīng)力時(shí)間和準(zhǔn)確率的把握,之后再訓(xùn)練聽(tīng)力部分的完整答題。 聽(tīng)力基礎(chǔ)不是很好的同學(xué)在考前至少要進(jìn)行20-30次聽(tīng)力的整體模擬訓(xùn)練,并且高效準(zhǔn)確地完成答題。 聽(tīng)力一直是很多考生懼怕的部分,但是沒(méi)有取巧的方法,只有依靠多聽(tīng)多訓(xùn)練,才能對(duì)聽(tīng)力中的語(yǔ)句有一定的敏感度,進(jìn)而準(zhǔn)確地答題。 總是敗給聽(tīng)力的各位,不妨按照這篇攻略,從現(xiàn)在開(kāi)始練習(xí),12月六級(jí)過(guò)過(guò)過(guò)! 爭(zhēng)取拿到好成績(jī)~ ?屠皓民領(lǐng)銜 四六級(jí)通關(guān)神器? ??????基礎(chǔ)班·沖刺押題班·白金班 直播錄播相結(jié)合,基礎(chǔ)強(qiáng)化沖刺全包括 ??不同水平,靈活選擇班型 $課程限時(shí)優(yōu)惠6折起$ 【基礎(chǔ)班】:380-424分,語(yǔ)法詞匯基礎(chǔ)薄弱 【沖刺班】:有一定基礎(chǔ),四六級(jí)做題技巧欠缺,刷分必選 【白金班】:380分以下,屢考不過(guò) 點(diǎn)擊立即免費(fèi)試聽(tīng)>> 屢考不過(guò)的建議選擇白金班

英語(yǔ)自我介紹常用表達(dá)
常用的表達(dá)方式,旨在幫助讀者構(gòu)建既專業(yè)又富有個(gè)人特色的自我介紹模板。 ? 一、開(kāi)場(chǎng)白:吸引注意,建立聯(lián)系 一個(gè)好的開(kāi)場(chǎng)白能夠迅速吸引聽(tīng)眾的注意力,為后續(xù)的自我介紹奠定良好的基調(diào)。常用的開(kāi)場(chǎng)白表達(dá)包括: 問(wèn)候與自我介紹開(kāi)頭:“Good morning/afternoon/evening, everyone. My name is [你的名字], and it's a great honor to be here today.” 簡(jiǎn)短而禮貌的問(wèn)候后直接報(bào)出姓名,并表達(dá)對(duì)場(chǎng)合的尊重。 建立聯(lián)系:“I'm particularly excited to be among such a distinguished group of professionals/students, as I share a passion for [共同興趣或領(lǐng)域].” 通過(guò)提及共同的興趣或領(lǐng)域,嘗試與聽(tīng)眾建立初步的聯(lián)系。 二、個(gè)人背景與教育經(jīng)歷 個(gè)人背景和教育經(jīng)歷是自我介紹中不可或缺的部分,它們能夠展現(xiàn)你的專業(yè)基礎(chǔ)和學(xué)術(shù)素養(yǎng)。 教育背景:“I recently graduated from [學(xué)校名稱], where I majored in [專業(yè)名稱]. During my studies, I was particularly fascinated by [具體課程或研究方向], which led me to conduct a research project on [項(xiàng)目主題].” 通過(guò)具體事例展示你在學(xué)習(xí)過(guò)程中的收獲和興趣點(diǎn)。 學(xué)術(shù)成就:“My academic journey has been marked by several achievements, including [具體獎(jiǎng)項(xiàng)或榮譽(yù)], which recognized my efforts in [具體領(lǐng)域].” 提及具體的學(xué)術(shù)成就,增強(qiáng)自我介紹的說(shuō)服力。 三、工作經(jīng)驗(yàn)與實(shí)習(xí)經(jīng)歷 對(duì)于職場(chǎng)人士或即將步入職場(chǎng)的學(xué)生而言,工作經(jīng)驗(yàn)和實(shí)習(xí)經(jīng)歷是展現(xiàn)個(gè)人能力的重要窗口。 工作經(jīng)驗(yàn)概述:“Prior to this, I had the opportunity to work at [公司名稱] as a [職位名稱]. In this role, I was responsible for [主要職責(zé)], which allowed me to develop skills in [具體技能,如項(xiàng)目管理、團(tuán)隊(duì)合作等].” 通過(guò)具體職責(zé)和技能展示你的工作經(jīng)驗(yàn)和成長(zhǎng)。 實(shí)習(xí)亮點(diǎn):“During my internship at [實(shí)習(xí)單位], I contributed to [具體項(xiàng)目或任務(wù)], which not only honed my [相關(guān)技能], but also taught me the importance of [如時(shí)間管理、溝通協(xié)調(diào)等職場(chǎng)軟技能].” 強(qiáng)調(diào)實(shí)習(xí)經(jīng)歷中的亮點(diǎn)和所

12月英語(yǔ)六級(jí)比6月份難?來(lái)看官方解答>>
距離2024年12月英語(yǔ)六級(jí)考試越來(lái)越近,同學(xué)們準(zhǔn)備的如何?很多同學(xué)好奇12月份的六級(jí)考試是不是要比6月份的六級(jí)考試難?今天@滬江英語(yǔ)四六級(jí)微信公眾號(hào)跟大家做出解答,希望對(duì)你有所幫助。 1.四六級(jí)成績(jī)?cè)斀?首先,四六級(jí)考試是水平測(cè)試而非選拔考試。詳解如下:四六級(jí)考試的滿分為710分,成績(jī)單只報(bào)告總分及聽(tīng)、讀、寫(xiě)譯三個(gè)單項(xiàng)的成績(jī)。 四六級(jí)成績(jī)單官方規(guī)定不設(shè)及格線,但一般四級(jí)達(dá)到425分及以上即可參加六級(jí)考試。所以,一般社會(huì)上、高校及用人單位采用425分作為及格線。 四六級(jí)成績(jī)從原始的100分換算成710分的過(guò)程較為復(fù)雜。簡(jiǎn)單點(diǎn)來(lái)說(shuō):四六級(jí)的總分以及單項(xiàng)成績(jī)反應(yīng)的是考生在本次參加四六級(jí)所有考生中

2024年12月英語(yǔ)四級(jí)閱讀理解模擬:電子產(chǎn)品的可循環(huán)
準(zhǔn)確,文中只提到plastics sandwich里層是100%的再生塑料。 4.[C] 推理判斷題。本題考査轉(zhuǎn)折處。最后一段倒數(shù)第2句中的Unfortunately一詞指出了用鎂作機(jī)殼的電視機(jī)很貴,從而暗示它們并不受消費(fèi)者歡迎,所以選項(xiàng)C正確。選項(xiàng)A屬原文明確表達(dá)的意思。本段第2句只指出鎂是一種理想的再生材料(ideal for recycling),因此選項(xiàng)B不對(duì);全文并未比較塑料和鎂哪個(gè)更好,因此選項(xiàng)D不對(duì)。 5.[A] 主旨大意題。文中作者只是客觀地描述亊實(shí),吿知讀者日本的電子產(chǎn)品再循環(huán)使用的一些新變化和新技術(shù),抓住這個(gè)主旨就能選出正確答案A。作者并未發(fā)表任何個(gè)人觀點(diǎn),也未做出任何指示或預(yù)測(cè)。 以上就是關(guān)于“2024年12月英語(yǔ)四級(jí)閱讀理解模擬:電子產(chǎn)品的可循環(huán)”的全部?jī)?nèi)容啦,祝同學(xué)們四級(jí)考試順利。
