　　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 Intemet 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 'pn-junction' 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.

　　答案與解析

　　23.C。題干：第二段的主要內容是__________。第二段的第一句是主題句，可知幾所大學的研究發現amorphous chalcogenides的電子特性可以改變，amorphous chalcogenides是數據技術必需的一種玻璃材料，其他句子具體解釋這個發現，所以C(一項新的發現)是正確答案。

　　24.B。題干：第三段的主要內容是__________。第三段沒有明顯的主題句，主要介紹了目前電腦使用電子進行信息的傳輸和應用的處理，但是這會引起處理速度的顯著下降(significant slowdown)，故B(目前電腦的問題)是正確答案。

　　25.D。題干：第四段的主要內容是__________。第四段的主題句為首句，即挑戰就是要找到一種單一的材料，可以有效地使用和控制光來攜帶信息，故D(研究的目的)是正確答案。

　　26.F。題干：第五段的主要內容是__________。第五段沒有明顯的主題句，主要說明了過去特別困擾研究者，但是現在已經發現如何廣泛使用玻璃來傳導負電子以及正電子，這使得該材料可以發揮光源的作用，故F(新材料的用途)是正確答案。

　　27.B。題干：研究的結果有助于電腦增加__________。按照出題順序與段落順序一致的原則，利用help computers to increase可以定位到第一段的最后一句，可知這將有效提高電腦的處理速度和功率，所以答案為B(處理速度)。

　　28.C。題干：目前電腦傳輸信息使用__________。利用題干關鍵詞Current和transfer information可以定位到第三段第一句，可知目前電腦使用電子進行信息的傳輸和應用的處理，所以該題答案為C(電子)。

　　29.F。題干：新的玻璃材料使得滿足不同的計算功能的__________成為可能。利用題干關鍵詞different computing functions可以定位到第二段的最后一句，可知通過這種玻璃材料可以使用光把不同的計算功能融進一個零件之中，從而形成全光系統，所以答案為F(全光系統)。

　　30.A。題干：玻璃被用在研究中是為了攜帶和處理__________。利用題干關鍵詞9lass和carry and process可以定位到第五段“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”，可知這種玻璃可以發揮光源、光導和光檢測的作用，從而可以攜帶和解釋光學信息，結合語境可知A(光學信息)是正確答案。
