1、2022年6月英语四级阅读理解101篇精析(13)2022年6月英语四六级考试太难?只是你没有找对方法而已!点击查看秘籍!点击进入免费试听 *点击进入免费试听四六级考试课程!The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff. Material science - once the least sexy techn

2、ology is bursting with new, practical discoveries led by superconducting ceramicsthat may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and

3、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 at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the micr

4、oscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and

5、 never rust or corrode.A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jacke

6、tsthat automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to

7、sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites plastic reinforced with fibers of graphite or other compounds made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantrymans li

8、fe by deflecting two bullets in the Grenada invasion.Some advanced materials are old standard with a new twist. The newest fiberoptic cable that carry telephone calls cross-country are made of glass so transparent that a piece of 101 miles thick is clearer than a standard window pane.But new materia

9、ls have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.1. How many

10、 new materials are mentioned in this passage?A TwoB ThreeC FourD Five2. 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 explai

11、n 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.DBecause it takes 10 years.4. Where lies success of a country in the New Age of supe

12、rstuff?A It lies in research.B It lies in investment.C It lies in innovation.D It lies in application. Vocabulary1. superstuff 超级材料2. superconducting ceramic 超导陶瓷3. exotic 奇妙的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

13、 玷污,损害风景的东西11. tinker 修补,调整12. amendable 听从于,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 可循环(运用的)17. infantryman 步卒18. deflect 使偏斜,使转向19. a new twist 一个新的观点,方法难句译注1. Material science once the least sexy technology is bursting with new, practicaldiscoveries

14、 led by superconducting ceramics that may revolutionize electronics.材料科学,一度曾是最无吸引力(最不起眼)的技术,正以崭新的 ,以超导陶瓷为首的种种好用性独创绽开新颜。这种超导陶瓷可能会使电子技术彻底变更。2. Some advanced materials are old standard with a new twist. The newest fiberopticcables that carry telephone calls cross-country are made of glass so transparen

15、t that a piece of101 miles thick is clearer than a standard window pane.有些高级材料是带有新方法的老标准。最新全国电话的光纤电缆由玻璃制成。这种玻璃透亮度极高,一片101英里厚的玻璃比一块标准的窗框玻璃还要清楚透亮。写作方法与文章大意这是一篇介绍“超导材料”的论说文,采纳一般到详细的分类写作手法。先指出将来时代的材料属于超导,然后再提出三种超导材料,再逐一说明。答案详解1. B 三种超导材料。答案再第一段最终一句“奇妙的塑料、玻璃和陶瓷”。下面各段详细讲这三种材料。其次段讲陶瓷:“新材料之关键在于探讨工作者不断提高在分子水

16、平上处理物质的实力。举陶瓷为例,由于它的脆性,长期来应用范围有限。但是通过改善导致脆性的微小缺陷,科学家制造出一种保持原有硬度和抗热性,但坚实得多的陶瓷”。第三段讲塑料。“类似的转折发生在塑料上,高强度的塑料建成了桥梁、溜冰场、直升机的叶轮。一种振动或推动就能发电的新型塑料用于电子吉他上,触及传感塑料用于机械手和空手道外衣上,它能自动记录每次击打。”后面谈及塑料垃圾可以处理,或者制造可分解还原的塑料制品。塑料内加入其他化合物加强性能。第四段讲有些高级材料由新的变更,最新的光纤电缆由玻璃制成,透亮度极高,101英里厚的一块其清楚度比一块一般窗玻璃还高。2. B 说明这种新材料对将来世界的意义。答案在第一段:“奇妙的塑料、玻璃和陶瓷肯定会象生物工
