  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 infmation using light. This development could significantly increase computer processing speeds power in the future.

  (2)The research by the University of Surrey, in collabation with the University of Cambridge the University of Southampton, has found it is possible to change the electronic properties of amphous chalcogenides, a glass material integral to data technologies such as CDs 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 infmation process applications. On the other h, data sources such as the Intemet rely on optical systems; the transfer of infmation using light. Optical fibers are used to send infmation around the wld 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 control light to carry infmation arotmd a computer. Much like how the web uses light to deliver infmation, we want to use light to both deliver process computer data," said project leader, Dr Rid Curry of the University of Surrey.

  (5) "This has eluded researchers f decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive ges, creating what are known as 'pn-junction' devices. This should enable the material to act as a light source, a light guide a light detect -- something that can carry interpret optical infmation. In doing so, this could transfm the computers of tomrow, allowing them to effectively process infmation at much faster speeds."

  (6) The researchers expect that the results of this research will be integrated into computers within ten years. In the sht term, the glass is already being developed used in next-generation computer memy technology known as CRAM, which may ultimately be integrated with the advances repted.

  答案与解析

  23.C。题干:第二段的主要内容是__________。第二段的第一句是主题句,可知几所大学的研究发现amphous chalcogenides的电子特性可以改变,amphous chalcogenides是数据技术必需的一种玻璃材料,其他句子具体解释这个发现,所以C(一项新的发现)是正确答案。

  24.B。题干:第三段的主要内容是__________。第三段没有明显的主题句,主要介绍了目前电脑使用电子进行信息的传输和应用的处理,但是这会引起处理速度的显著下降(significant slowdown),故B(目前电脑的问题)是正确答案。

  25.D。题干:第四段的主要内容是__________。第四段的主题句为首句,即挑战就是要找到一种单一的材料,可以有效地使用和控制光来携带信息,故D(研究的目的)是正确答案。

  26.F。题干:第五段的主要内容是__________。第五段没有明显的主题句,主要说明了过去特别困扰研究者,但是现在已经发现如何广泛使用玻璃来传导负电子以及正电子,这使得该材料可以发挥光源的作用,故F(新材料的用途)是正确答案。

  27.B。题干:研究的结果有助于电脑增加__________。按照出题顺序与段落顺序一致的原则,利用help computers to increase可以定位到第一段的最后一句,可知这将有效提高电脑的处理速度和功率,所以答案为B(处理速度)。

  28.C。题干:目前电脑传输信息使用__________。利用题干关键词Current和transfer infmation可以定位到第三段第一句,可知目前电脑使用电子进行信息的传输和应用的处理,所以该题答案为C(电子)。

  29.F。题干:新的玻璃材料使得满足不同的计算功能的__________成为可能。利用题干关键词different computing functions可以定位到第二段的最后一句,可知通过这种玻璃材料可以使用光把不同的计算功能融进一个零件之中,从而形成全光系统,所以答案为F(全光系统)。

  30.A。题干:玻璃被用在研究中是为了携带和处理__________。利用题干关键词9lass和carry process可以定位到第五段“This should enable the material to act as a light source,a light guide a light detect--something that can carry interpret optical infmation”,可知这种玻璃可以发挥光源、光导和光检测的作用,从而可以携带和解释光学信息,结合语境可知A(光学信息)是正确答案。
