1 Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times. Adaptable glasses Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透镜）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make. The wind-up radio When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (发电机) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design. The Dyson cleaner In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds. The Zapata fly-board Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200. So keep dreaming and inventing. One day you might get it right. 小题1:What can we learn about Adaptable glasses? A．They are very expensive. B．The inventor is a student. C．The glasses are fragile. D．They don’t look very nice. 小题2:Which invention won an award? A．Adaptable glasses. B．The wind-up radio. C．The Dyson cleaner. D．The Zapata fly-board. 小题3:The Dyson cleaner was invented with the purpose of _________. A．helping people use cleaners more easily B．making Dyson a rich businessman C．keeping the house cleaner than before D．taking the place of human cleaners

5 党的十八大报告提出，扎实推进社会主义文化强国建设，必须坚持文化体制改革。在文化消费方面，文化消费水平是同经济基础、消费需求和实际供给能力密切相关的。业内人士分析认为，当人均年收入超过8 000美元时，人们对于文化娱乐的需求将呈现井喷式增长。文化是民族的血脉，是人民的精神家园，深化文化体制改革，推动社会主义文化大发展大繁荣，对于全面贯彻落实科学发展观，加快转变经济发展方式、满足人民群众精神文化需求、维护安定团结政治局面、全面建成小康社会具有重大而深远的意义。结合材料运用上层建筑一定要适合经济基础状况的规律，分析我国深化文化体制改革的必要性。（10分）
