23-Thursday 纳米技术 177词

题材: 纳米技术  词数: 177  建议阅读时间: 4分钟

阅读下面的短文,选择正确答案。

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 (纳米技术)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 (纳米机器人)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 .

参考译文

想象一下:电视屏幕的大小、厚薄和一张纸一样。你可以放在口袋里拿走,当你想看节目时再拿出来。想象一下:一把吉他小到肉眼看不见,但你能听到琴弦被拨动时发出的声响。

纳米技术是一门从极小处入手处理问题的科学,全世界都在对它进行研究和开发。许多科学家说,纳米技术将导致下一场工业革命。

也许纳米技术会对医学产生最大的影响。想象一下药品中的纳米机器人。数以千计、甚至数以百万计的微型机器被放进人体去执行特殊任务。比如,它们可以用来发现并清除人体内的癌细胞或病毒。有些机器会永久性地待在人体内,以帮助不能正常运转的器官。

这一切什么时候才能实现呢?科学家预测,在未来的30年内,大多数目标都有可能达到。世界各地数以千计的科学家正在研制这些微型机器。纳米技术的时代即将到来。
