请根据短文内容,回答题。 New Research Lights the Way to Super-fast Computers (1) New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future. (2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems. (3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the Internet rely on optical systems; the transfer of information using light. Optical fibers are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing. (4) "The challenge is to find a single material that can effectively use and control light to carry information arotmd a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey. (5) "This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as &39;pn-junction&39; devices. This should enable the material to act as a light source, a light guide and a light detector -- something that can carry and interpret optical information. In doing so, this could transform. the computers of tomorrow, allowing them to effectively process information at much faster speeds." (6) The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.$amp; Paragraph 2 __________ 查看材料

【简答题】灌木丛上会落下星星 朱成玉 生命中有太多的刺痛和悲伤,使得那些美好更为深重。你是否依然愿意相信那些美好,并且等? 我愿意。 我愿意,我相信,灌木丛上会落下星星,冬天,穷人的房檐上,会铺满钻石。 我相信岁月,相信时针、分针和秒针,顺着同一个方向,分别如蜗牛、乌龟和梅花鹿的步子,追赶着看不见的美好。 我相信爱的存在,它温暖的是你日渐凋落的灵魂,也温暖着他人疑虑重重的眼神。 我愿意相信一个承诺,并且等。...
