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.

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(duì)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(cuò)誤的地方的資源。只要對(duì)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(duì)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(dòng)植物的生存和生長(zhǎng)。? 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。
