2、y? The green movement is not new to fashion, and many designers and manufacturers have been actively seeking out ways to ensure their garments have less of an environmental impact. But what if your clothes were actually able to have a 1 impact on the environment? This vision is one shared by the two

3、 founders of Catalytic Clothing(触媒服装): Professor Tony Ryan, a scientist from the University of Sheffield, and Professor Helen Storey, a designer and artist from the London College of Fashion.

4、abric 2 that can break down pollutants in the air. In a sense, its a recycling of an existing technology that exists in toothpaste and sunscreen, Professor Storey explains. The additive contains nanoparticles of titanium dioxide which act as a catalyst (触媒剂；催化剂). When light hits these particles, the

5、y react with oxygen to make what is essentially a peroxide(过氧化物) bleach. This in turn reacts with air 3 such as nitric oxide and breaks them down. While this technology could be used to create an entirely new fabric, Professor Ryan thinks that it has greater potential as an additive. It only needs t

6、o be on the surface, he says. You dont 4 it in the fibers, and that means that its really easy to upgrade existing fabrics with the technology. We think the best way to do this is via the laundry, because everyone washes their clothes. Jeans have been a particular focus of Catalytic Clothing, both b

And while the amount of air pollutants broken down by any one individual wearing catalyzed jeans is minor, 6 , we can have a huge impact on the quality of the air and therefore respiratory health, Store

It seems that the Royal Shakespeare Company and Shakespeares Globe wont have to change their names any time soon. The squabble so beloved by academics, conspira

11、cy (阴谋) theorists and Hollywood film-makerswhich only surfaced in the mid-19th century but continues to 11 onover the authorship of Shakespeares plays, may finally be called to a halt by a new book. In Shakespeare Beyond Doubt, leading scholars organize the arguments and evidence to prove that Shake

12、speare really did write Shakespeares plays. It puts paid to 12 that Shakespeare was the Earl of Oxford (as suggested by the movie Anonymous), or Christopher Marlowe or Francis Bacon, or even Queen Elizabeth when she was having a day off from running the country. Great. That means the rest of us can

13、just go on seeing and enjoying the astonishing plays, which may have 13 authorship, but which are constantly revealing in their examination of what it means to be human. Except that it wont. The arguments, between those who want to rewrite 14 history and those who dont, will keep going, constantly f

14、ueled by any kind of conspiracy theorythe madder the betterand the fact that there is now so much money, and so many academic careers, 15 up in the Shakespeare industry. There is a 16 in Alan Bennetts play Kafkas Dick when one of the characters, Sydney, admits hed much rather read about writers than

15、 read what they write. His wife, Lynda, is 17 uninterested in the poems of WH Auden, but alights on juicy tidbits(趣闻) about the poet including his preference for not wearing underpants. It sometimes seems as if the 18 authorship debate around Shakespeares plays is full of Sydneys and Lyndaspeople fo

16、r whom the life of the writer is infinitely more important than the works themselves. The plays are what count and they will 19 the debate, no matter whose name is on the title page, whether written alone or in 20 , and whether someone can definitively prove whether the author was wearing underpants

So it should be, because the plays the thing.（分数：25.00）A. lengthy B. transformation C. absorption D. bursting E. combat F. permanently G. appreciable H. manipulate I. transparent J. deliberately K. bestow L. imperfections M. recyclable N. neutralization O. corrode The Stone Age, the Iron Ag

18、e. 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 scienceonce the least sexy technologyis 21 with new, practical discoveries led by superconducting ceramics (超导陶瓷) that may revolutionize electronics

19、. 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 ceramics will shape the future just as surely as have genetic engineering and computer science. The key to the new

20、materials is researchers increasing ability to 22 substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic 23 that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and he

21、at 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 never rust or 24 . A similar 25 has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter r

22、otors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets(空手道外衣) that automatically record each punch and chop. Even plastic litter, which once threatened to 26 blot the landscape, has proved amenable t

25、e calls cross-country are made of glass so 29 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 transition could prove difficult, for switching requires 30 research and investment. It can be said a fir

27、. qualify O. overall To understand the marketing concept, it is only necessary to understand the difference between marketing and selling. Not too many years ago, most industries concentrated 31 on the efficient production of goods, and then relied on persuasive salesmanship to move as much of these

28、 goods as possible. Such production and selling focuses on the needs of the seller to produce goods and then 32 them into money. Marketing, on the other hand, 33 that emphasis is placed on the wants of consumers. It begins with analyzing the 34 and demands of consumers and then producing goods that

29、will satisfy them. This eye-on-the-consumer 35 is known as the marketing concept. It simply means that instead of trying to sell whatever is easier to produce, the makers first try to find out what the consumer wants to buy and then go about making it 36 for purchase. Every stepdesign, production, 3

There are always two sides to every business activitythe firm and the consumerand each must be satisfied before trade 39 Successful merchants and producers, howeve

31、r, recognize that the surest route to profit is through understanding customers. When Coca Cola changed the flavor of its drink in mid-1985, the non-acceptance by a 40 portion of the public brought about a quick restoration of the Classic Coke. This is a good example of the importance of satisfying
