2024年12月英语四级阅读理解模拟:超导材料
2024年12月英语四级考试在即,同学们要认真备考哦。今天为大家带来的是2024年12月英语四级阅读理解模拟:超导材料,一起来看看吧。 2024年12月英语四级阅读理解模拟:超导材料 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 超级材料 2. superconducting ceramic 超导陶瓷 3. exotic 神奇的 4. shape 塑造,成型 5. brittleness 脆性 6. polymer 聚合体 7. karate jacket 空手道外衣 8. touch sensor 触及传感器 9. each punch and chop 每一个击、打 10. blot 玷污,损害风景的东西 11. tinker 修补,调整 12. amendable 服从于,遵循的 13. biodegradable 能生物递减分解的 14. six-pack rings 放六个罐子的环状物 15. decompose 分解 16. recyclable 可

2024年12月英语六级阅读理解全真模拟题(2)
2024年12月英语六级考试将在12月14日下午举行,大家要认真复习哦。今天@沪江英语四六级微信公众号为大家整理了2024年12月英语六级阅读理解全真模拟题(2),希望对你有所帮助。 2024年12月英语六级阅读理解全真模拟题(2) I live in the land of Disney, Hollywood and year-round sun. You may think people in such a glamorous, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness. Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more abiding emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends. I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to glamorous parties, fancy cars, expensive homes, everything that spells “happiness”. But in memoir after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages, troubled children and profound loneliness. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he’s honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its most distinguishing features. Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out ever they want and sleep as late as they want. Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those rich and glamorous people we were so sure are happy because they are always having so much fun actually may not be happy at all. 1.Which of the following is true? A.Fun creates long-lasting satisfaction. B.Fun provides enjoyment while pain leads to happiness. C.Happiness is enduring whereas fun is short-lived. D.Fun that is long-standing may lead to happiness. 2.To the author, Hollywood stars all have an important role to play that is to __. memoir after memoir about their happiness. the public that happiness has nothing to do with fun. people how to enjoy their lives. happiness to the public instead of going to glamorous parties. 3.In the author’s opinion, marriage___. s greater fun. to raising children. tes commitment. in pain. 4.Couples having infant children___. lucky since they can have a whole night’s sleep. fun in tucking them into bed at night. more time to play and joke with them. happiness from their endeavor. 5.If one get the meaning of the true sense of happiness, he will__. playing games and joking with others. the best use of his time increasing happiness. a free hand to money. himself with his family. 参考答案:CBCDB 以上就是今天的学习内容啦。大家要利用好最后一个月的时间多多练习,并且多进行模考熟悉考试流程。小编预祝大家顺利通过英语六级~

英语发音准确度提升技巧
朗读就是听不懂,所以发音也会比较影响听力。 3.划分句群 另外还要做的一件事就是通览一下文章大意。知道文章在讲什么,就知道哪段和哪段不能分开,哪里是可以断开换气不影响整体理解的。你也可以在需要换气的地方用竖线斜线标记一下,这样读到要断句的地方就知道调整呼吸了。 二、提升英语发音的技巧 1.每天听播客 播客是不用付费的,可下载的音频节目,你可以把它放在你的mp3播放器上。这是一个很好的选择,因为你可以在堵车或任何时候方便的时候听。 2.专注于英语歌词答发音 语言的音乐元素对于良好的发音都是必不可少的。你不需要成为一名音乐家,也不需要听更多的英语歌曲(尽管这两种方法都有帮助),但你应该注意母语人士的语调。它是语言

2024年12月英语四级阅读理解模拟:电视有害
理了2024年12月英语四级阅读理解模拟:电视有害,一起来看看吧。 2024年12月英语四级阅读理解模拟:电视有害 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 转动眼珠,瞪眼 goggle box (英俚)电视机 2. gulp 狼吞虎咽 3. telly 电视机 4. pacifier 平息者,抚慰者。这里指平静人,使人不吱声的东西。 5. rubbishy 垃圾的,无价值的 6. sadism 施淫虐 7. glue 胶(水);粘牢 glue to the sets 和电视机粘在一起,指成了电视迷 8. hypnotic 催眠的 写作方法与文章大意 这是一篇论说“电视有害”的文章。采用对比分析手法。先提出问题,对比过去和现在“过去在业余时间,我们享受文明的欢乐,有各种嗜好,招待朋友,访友,外出娱乐,在家读书听音乐……现在一切受

2024年12月英语六级阅读理解全真模拟题(1)
距离2024年12月英语六级考试只有一个月啦,各位小伙伴准备的如何?今天@沪江英语四六级微信公众号为大家准备了2024年12月英语六级阅读理解全真模拟题(1),检验一下最近的学习成果。一起来看看吧~ 2024年12月英语六级阅读理解全真模拟题(1) Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging. Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system. The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless. 1.What is the author’s main purpose in the passage? A.To explain the specific functions of various hormones. B.To provide general information about hormones. C.To explain how the term “hormone” evolved. D.To report on experiments in endocrinology. 2.The passage supports which of the following conclusions? A.The human body requires large amounts of most hormones. B.Synthetic hormones can replace a person’s natural supply of hormones if necessary. C.The quantity of hormones produced and their effects on the body are related to a person’s age. D.The short child of tall parents very likely had a hormone deficiency early in life. 3.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___. sleep. the endocrine glands. control of the nervous system. strenuous exercise. 4.The word “liberate” could best be replaced by which of the following? A.Emancipate B.Discharge C.Surrender D.Save 5.According to the passage another term for exocrine glands is___. glands ine glands ss glands inal glands. 答案:BDCBA 以上就是今天的六级阅读模拟题,希望大家利用好最后的一个月认真备考。祝大家能顺利通过考试
