    2024年12月英語四級考試在即,同學(xué)們要認(rèn)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(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.

  • 2024年12月英語六級作文預(yù)測:自信

    理了2024年12月英語六級作文預(yù)測:自信,希望對你有所幫助。 2024年12月英語六級作文預(yù)測:自信 Directions: For this part, you are allowed 30 minutes to write an essay based on the picturebelow. You should start you essay with a brief description of the picture and then comment on confidence. You should write at least 150 words but no more than 200 words. 預(yù)測范文 As we can see from the picture, in a residential community with a television antenna on the roof, an upset young man is talking to his friend walking beside him along the street. It is apparent that the former assumes that someone else is more qualified than him. The young always give up because the problem is beyond their ability to cope with. Superficially, it seems to be somewhat reasonable, but when weighing in the mind, we find there is an apparent tendency underlying this phenomenon: the lack of confidence. Firstly, it is well-known that we exist in a dynamic world with various difficulties. We can do nothing but face them. Secondly, attitude is the key point to take the first step. Assuming bravery and confidence to solve the problem, you will find the question is not as “huge” as you imagine. So, with confidence and the right assessment of difficulties, try and exert our strength, and then we will overcome all the difficulties. On the whole, I believe we young people should face the difficulties in the right manner. And nothing is impossible, just do it. 參考譯文 如圖所示,在一個屋頂架起電視天線的住宅小區(qū),一個沮喪的年輕人正在和沿著街道走在身旁的一個朋友聊天。顯而易見,前者認(rèn)為別人比自己能力更強(qiáng)。 由于問題超出他們應(yīng)對的能力,年輕人總是放棄。表面上看,這幅圖畫似乎有一些道理,但當(dāng)我們仔細(xì)思考時,我們就會發(fā)現(xiàn)在這個現(xiàn)象之下有一個明顯的趨勢:缺乏自信。首先,眾所周知,我們生活在一個充滿各種困難的多元化世界。我們別無選擇,只能面對。其次,態(tài)度是采取第一步的關(guān)鍵。擁有勇氣和信心來解決問題,你就會發(fā)現(xiàn)問題并非你想象的那么“嚴(yán)重”。因此,擁有信心和對困難的正確估計(jì),竭盡全力,我們將解決所有的困難。 總而言之,我認(rèn)為我們年輕人應(yīng)該以正確的方式面對困難。世上無難事,只怕有心人。

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(jìn)行適當(dāng)?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(fèi),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?yàn)橥ㄟ^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(hù)我們賴以生存的環(huán)境。
