Unit 3 Computers
Questions：
1・According to the text, how unll quantum computing work? 答案Quantum computing will work by using transistors・
2. What is the text mainly about?
答案The text is mainly about what the future of the computer is.
Computer technology is still developing rapidly. The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful・It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now. A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years. Two of the most interesting areas of computing that are currently being developed are quantum computing① and nanotechnology?
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today. Quantum computers could be able to do what modem supercomputers are unable to do by using transistors that are able to take on many states at the same time.
Nanotechnologj' could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size. These computers could be incorporated③ into everyday objects, including electrical appliances®, clothes and even the human body. We will be able to use computers in new and unimaginable ways. They will become a part of our lives rather than simply being a box that is used only for specific purposes, such as work.
Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy healthier and happier lives.
电脑科技仍然发展得很快，未来的电脑在成本上减少的同时将继续在价值和性能上增加，它会变得更小，但更快更强大。

以现在正在发展的技术类型为基础，猜测一下未来电脑可能是什么样的，在新技术方面，一些有了
很
大的进展，但也有一些还在初级阶段，可能要几年才能准备好应用。

一直在发展的两个最有意义的
领域是
量子计算使未来的电脑可能比现在最
快的电脑还要快，量子电脑能够做现代超级电脑不能做的事情, 它可以通过晶体管同时做许多事情。

纳米技术尽管很微小，但通过创造非常强大的电脑也能改变电脑的面貌。

这些电脑能够并入日常物品 中，包括电器、衣服、甚至人的身体。

我们能以新的和难以想象的方式来使用电脑。

他们会成为我们生活 的一部分，而不仅仅是一个盒子——只用于专门的目的，例如工作。

量子计算和纳米技术将能够起新的作用，这会使我们的生活更绿色仰保），我们也能享受更健康更快乐 的生活。

【注】①quantum computing 量子计算 ②nanotechnology n.纳米技术 ③incorporate v.并入
