问题    As high-tech materials invade high-street fashion, prepare for clothes that are cooler than silk or warmer than wool, keep insects at arm’ s length, and emit many pinpricks of coloured light.
   The convergence of fashion and high technology is leading to new kinds of fibres, fabrics and coatings that are imbuing clothing with egually wondrous powers. Corpe Nove has made clothes that can change according to external heat levels. And at Nexia Biotechnologies scientists have found fibres similar to those in nature.

   A big impact is already being made at the molecular level. Nano-Tex can make material that rarely needs washing. Meanwhile, Schoeller Textil uses material that can make you warmer or cooler.
   Sensory Perception Technologies (SPT) embodies an entirely different application of nanotechnology. Created in 2003 by Quest International, a flavour and fragrance company, and Woolmark, a wool textile organisation, SPT is a new technique of embedding chemicals into fabric. Though not the first of this type, SPT’ s durability (evidently the microcapsule containing the chemicals can survive up to 30 washes) suggests an interesting future. Designers could incorporate signature scents into their collections. Sportswear could be impregnated with anti-perspirant. Hayfever sufferers might find relief by pulling on a T-shirt, and so on.
   The loudest buzz now surrounds polylactic acid (PLA) fibres—and, in particular, one brand-named Ingeo. Developed by Cargill Dow, it is the first man-made fibre derived from a 100% annually renewable resource. This is currently maize (corn) , though in theory any fermentable plant material, even potato peelings, can be used. In performance terms, the attraction for the 30-plus clothes makers signed up to use Ingeo lies in its superiority over polyester (which it was designed to replace).

   As Philippa Watkins, a textiles specialist, notes, Ingeo is not a visual trend. Unlike nanotechnology, which promises to " transform" what clothes can do, Ingeo ’ s impact on fashion will derive instead from its emphasis on using natural sustainable resources. Could wearing synthetic fabrics made from polluting and non-renewable fossil fuels become as uncool as slipping on a coat made from animal fur? Consumers should expect a much wider choice of " green" fabrics. Alongside PLA fibres, firms are investigating plants such as bamboo, seaweed, nettles and banana stalks as raw materials for textiles. Soya bean fibre is also gaining ground. Harvested in China and spun in Europe, the fabric is a better absorber and ventilator than silk, and retains heat better than wool.
   Elsewhere, fashion houses—among them Ermenegildo Zegna, Paul Smith and DKNY—are combining fashion with electronics. Clunky earlier attempts involved attaching electronic components to the fabrics after the normal weaving process. But companies such as SOFTswitch have developed electro-conductive fabrics that behave in similar ways to conventional textiles.
   Could electronic garments one day change colour or pattern? A hint of what could be achieved is offered by Luminex, a joint venture between Stabio Textile and Caen. Made of woven optical fibres and powered by a small battery, Luminex fabric emits thousands of pinpricks of light, the colour of which can be varied. Costumes made of the fabric wowed audiences at a production of the opera Aida in Washington, DC, last year.
   Yet this ultimate of ambitions has remained elusive in daily fashion, largely because electronic textiles capable of such wizardry are still too fragile to wear. Margaret Orth, whose firm International Fashion Machines makes a colour-changing fabric, believes the capability is a decade or two away. Accessories with this chameleon-like capacity—for instance, a handbag that alters its colour—are more likely to appear first.
Questions 56 ~ 60
Fill in the blanks below with information from the passage, using no more than two words for each blank.

选项
答案small battery
解析 文章倒数第二段提到，“Luminex由编织的光纤制成，由一个小电池供电，它能发出成千上万的光点，这些光点的颜色可以改变”。由此可知，Luminex纤维需要一个小电池供电才能工作。故填入small battery。
