    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.

    我們漢語中的“占著茅坑不拉屎”的意思相同。 3、英語口語練習(xí)素材:英語口語練習(xí)三 A: I am sorry for getting in your hair.對不起,給您添麻煩了。 B: It doesn’t matter.沒關(guān)系。 【解詞釋義】Get in one’s hair美國常用的俚語,其意思是“惹惱某人,是某人煩惱,給某人帶來麻煩”等意思。 4、英語口語練習(xí)素材:英語口語練習(xí)四 A: I dream of being a writer. But I am afraid maybe it is just a pipe dream.我夢想成為一名作家,但是恐怕是白日夢。 B: You should believe yourself. I will stand by you forever.你要相信自己,我永遠(yuǎn)會支持你的。 【解詞釋義】Pipe是“煙斗”的意思,引申為“鴉片”的意思,那么pipe dream則是形容鴉片上癮者陷入幻覺的狀態(tài)。Pipe dream與鴉片沒有任何瓜葛,而是用來指代“白日夢、幻想、空想‘知心妄想或一場春夢”。 5、英語口語練習(xí)素材:英語口語練習(xí)五 A: Oh, my God! You could stop a clock.天啊,你看起來臉色好差。你看起來很不舒服。 B: I have been sick for two weeks.我已經(jīng)病了2個(gè)星期了。 【解詞釋義】Stop a clock在美語中是用來形容一個(gè)人樣子“其丑無比” &ldq uo;非常難看”。在上文中,stop a clock牽涉到的主題是“人的健康”問題,形容一個(gè)人病了,精神萎靡,面容憔悴等等難看樣子。 6、英語口語練習(xí)素材:英語口語練習(xí)六 A: Did you have a sleep tight last night?你昨晚睡得好嗎? B: I have a sleepless night.我失眠了。 【 解詞釋義】Sleep tight源于美國版的“寶貝,晚安。”即:Sleep tight and don’t let the bedbugs bite. (睡得好覺,別讓臭蟲咬。)在19世紀(jì),美國孩子臨睡前最喜歡聽父母這樣對他們說。其中的tight相當(dāng)于soundly,well。Sleep tight的意思是“睡得很甜,很香”。 有人認(rèn)為sleep tight和海軍有直接聯(lián)系,因?yàn)檐娪玫暮\娪玫氖堑醮?,只有把吊床的繩子勒緊了,他們才能睡得舒服些。在這里tight的意思就是“stretched or down out fully”,意思是“拉緊的,繃緊的”。 Sleep tight的英文解釋為:to sleep warm and safe. It is usually said with good night to someone going to bed. 它可以單獨(dú)使用,用于口語短句中,也可以如材料是必須的。今天我們?yōu)榇蠹艺砹擞⒄Z口語練習(xí)材料對話中和動(dòng)詞“have”連用做句子的謂語,即:have a sleep tight。 以上就是為大家整理的英語口語練習(xí)材料介紹的相關(guān)內(nèi)容,希望能夠?qū)Υ蠹矣兴鶐椭?。練?xí)材料有很多,大家可以去書店看看,也可以去滬江網(wǎng)上了解,途徑很多。
