举例

Unit 3 Computers

P.35              Computer facts

Smaller and better

In the 1940s, the first computers were bigger than cars. Now computers are becoming smaller and better.

Some computers are tiny. You may be unaware of them. There is probably one inside your TV or washing machine. You depend on computers more than you realize.

What can we do with computers?

We can use computers to calculate. They can calculate at a faster speed than we can and almost never give wrong answers. We can also type and draw things with them. In addition, computers can do important jobs like operating railways and flying planes and spaceships.

Is a computer cleverer than me?

The answer is “No”. Your brain can produce new ideas but computers cannot. However, one day computers may be able to a better job than human beings. For example, they may be better than doctors at doing their job.

What will happen to us if computers can do all our jobs? Will we have nothing to do? Computers may change our lives, but will they make them better?

电脑的事实

越小越好

在1940年代,第一台计算机比汽车大。现在电脑变得越小越好。

一些电脑很小。你可能都没有意识到他们。可能在你的电视或洗衣机里就有一个。你比你了解到的更加依赖电脑。

我们可以用电脑做什么?

我们可以用电脑来计算。他们可以以更快的速度比我们所能计算,几乎从未给错误的答案。我们也可以用它们打字和画画。此外,电脑能做重要的工作如操作铁路系统，驾驶飞机和宇宙飞船。

计算机比我聪明吗?

答案是“不”。你的大脑能产生新想法,但计算机不能。然而,有一天计算机可以比人类更好的工作。例如,他们可能比医生更好地做他们的工作。

如果电脑能做所有的工作会对我们发生什么?我们会无事可做吗?电脑可能会改变我们的生活,但是他们会使生活更好吗?
