23-Thursday 納米技術(shù) 177詞

題材： 納米技術(shù)　 詞數(shù)： 177　 建議閱讀時間： 4分鐘

閱讀下面的短文，選擇正確答案。

Imagine this：a television screen has the size and thickness of a piece of paper．You carry it around in your pocket and take it out when you want to watch a show．Imagine a guitar so tiny that you can't see it with the human eye，but you can hear sound when its strings are pulled．

Nanotechnology （納米技術(shù)）is the science that deals with doing things in a very small way，and it is being studied and developed all over the world．Many scientists say nanotechnology will produce the next industrial revolution．

Perhaps nanotechnology will have the biggest influence on medical science．Imagine nanobots （納米機器人）in medicine．Thousands or even millions of tiny machines can be sent into the human body with specific tasks．For example，they can be designed to find and destroy cancer cells or viruses．Other machines may stay in the human body for ever to help organs that are not working properly．

When could all of these happen？Scientists predict that most of these are possible in the next 30 years．Thousands of scientists around the world are working on these micro-machines．Nanotechnology is just around the corner ．

參考譯文

想象一下：電視屏幕的大小、厚薄和一張紙一樣。你可以放在口袋里拿走，當你想看節(jié)目時再拿出來。想象一下：一把吉他小到肉眼看不見，但你能聽到琴弦被撥動時發(fā)出的聲響。

納米技術(shù)是一門從極小處入手處理問題的科學(xué)，全世界都在對它進行研究和開發(fā)。許多科學(xué)家說，納米技術(shù)將導(dǎo)致下一場工業(yè)革命。

也許納米技術(shù)會對醫(yī)學(xué)產(chǎn)生最大的影響。想象一下藥品中的納米機器人。數(shù)以千計、甚至數(shù)以百萬計的微型機器被放進人體去執(zhí)行特殊任務(wù)。比如，它們可以用來發(fā)現(xiàn)并清除人體內(nèi)的癌細胞或病毒。有些機器會永久性地待在人體內(nèi)，以幫助不能正常運轉(zhuǎn)的器官。

這一切什么時候才能實現(xiàn)呢？科學(xué)家預(yù)測，在未來的30年內(nèi)，大多數(shù)目標都有可能達到。世界各地數(shù)以千計的科學(xué)家正在研制這些微型機器。納米技術(shù)的時代即將到來。
