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(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

    理了2024年12月英語四級閱讀理解模擬:電視有害,一起來看看吧。 2024年12月英語四級閱讀理解模擬:電視有害 Yes, but what did we use to do before there wastelevision? How often we hear statements like this! Television hasn't been with us all that long, but weare already beginning to forget what the world was like without it. Before we admitted the one-eyed monster into our homes, we never fond it difficult to occupy our spare time. We used toenjoy civilized pleasures. For instance, we used to have hobbies, we used to entertain ourfriends and be entertained by them, we used to go outside for our amusements to theatres, cinemas, restaurants and sporting events. We even used to read books and listen to music andbroadcast talks occasionally. All that belongs to the past. Now all our free time is regulatedby the goggle box. We rush home or gulp down our meals to be in time for this or thatprogramme. We have even given up sitting at table and having a leisurely evening meal, exchanging the news of the day. A sandwich and a glass of beer will do anything, providing itdoesn't interfere with the programme. The monster demands and obtains absolute silenceand attention. If any member of the family dares to open his mouth during a programme, he isquickly silenced. Whole generations are growing up addicted to the telly. Food is left uneaten, homeworkundone and sleep is lost. The telly is a universal pacifier. It is now standard practice formother to keep the children quiet by putting them in the living-room and turning on the set. Itdoesn't matter that the children will watch rubbishy commercials or spectacles of sadism andviolence so long as they are quiet. There is a limit to the amount of creative talent available in the world. Every day, television consumes vast quantities of creative work. That is why most of the programmes areso bad: it is impossible to keep pace with the demand and maintain high standards as well. When millions watch the same programmes, the whole world becomes a village, and society isreduced to the conditions which obtain in preliterate communities. We become utterlydependent on the two most primitive media of communication: pictures and the spokenword. Television encourages passive enjoyment. We become content with second-handexperiences. It is so easy to sit in our armchairs watching others working. Little by little, television cuts us off from the real world. We get so lazy, we choose to spend a fine day insemi-darkness, glued to our sets, rather than go out into the world itself. Television may be ssplendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to real living when we spend aholiday by the sea or in the mountains, far away from civilization. In quiet, naturalsurroundings, we quickly discover how little we miss the hypnotic tyranny of King Telly. 1. What is the biggest harm of TV? [A] It deprives people of communication with the real world. [B] People become lazy. [C] People become dependent on second-hand experience. [D] TV consumes a large part of one's life. 2. In what way can people forget TV? [A] Far away from civilization. [B] To a mountain. [C] By the sea. [D] In quiet natural surroundings. 3. What does a mother usually do to keep her children quiet? [A] Let them watch the set. [B] Put them in the living room. [C] Let them watch the rubbish. [D] Let them alone. 4. What does the first sentence in the first paragraph mean? [A] We found it difficult to occupy our spare time. [B] We become addicted to TV. [C] What we used to do is different from now. [D] We used to enjoy civilized pleasures. Vocabulary 1. goggle 轉(zhuǎn)動眼珠,瞪眼 goggle box (英俚)電視機 2. gulp 狼吞虎咽 3. telly 電視機 4. pacifier 平息者,撫慰者。這里指平靜人,使人不吱聲的東西。 5. rubbishy 垃圾的,無價值的 6. sadism 施淫虐 7. glue 膠(水);粘牢 glue to the sets 和電視機粘在一起,指成了電視迷 8. hypnotic 催眠的 寫作方法與文章大意 這是一篇論說“電視有害”的文章。采用對比分析手法。先提出問題,對比過去和現(xiàn)在“過去在業(yè)余時間,我們享受文明的歡樂,有各種嗜好,招待朋友,訪友,外出娛樂,在家讀書聽音樂……現(xiàn)在一切受

    Labor-intensive Labor-intensive是指勞動密集型的,它是指單位勞動占用的資金數(shù)量較少,勞動消耗所占的比重較大的。在勞動的消耗中,也不僅指簡單的體力勞動,而且還包括復雜的、高級的、腦力的勞動消耗。 我們來看2個例句: Largely because China is not quite ready to dismantle labor-intensive industries that still provide much-needed jobs at home. 這很大程度上是因為中國沒有做好準備,放棄仍在提供急需的國內(nèi)就業(yè)崗位的勞動密集型產(chǎn)業(yè)。 Tourism

    理了2024年12月英語六級作文預測:自信,希望對你有所幫助。 2024年12月英語六級作文預測: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,前者認為別人比自己能力更強。 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,但當我們仔細思考時,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“嚴重”。因此,擁有信心和對困難的正確估計,竭盡全力,我們將解決所有的困難。 總而言之,我認為我們年輕人應(yīng)該以正確的方式面對困難。世上無難事,只怕有心。

    2024年12月英語四級考試將在12月14日早上舉行,同學們在考前要多練多背哦。今天學習的內(nèi)容是2024年12月英語四級作文預測: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。
