Before Computers

Before Computers Have you ever wondered how people typed before computers? More than one hundred years ago, people started using machines that sat on their desks. They were called typewriters. They had keyboards just like computers. But they were very different. There was no screen to look at. You would put a piece of paper in the typewriter. Each letter on the keyboard was connected to a metal arm that reached up and stamped the paper with ink as you typed! lf you made a mistake, you had to start over with a new piece of paper or use a special drop of white paint to cover your mistake. These typewriters had hundreds of moving parts and were very hard to fix.

以前是怎么打字的呢? 你有没有想过电脑出现以前人们是怎么打字的? 一百多年前，人们开始使用放在桌子上的机器。它们被称为打字机。他们有像电脑一样的键盘。但他们非常不同。 没有屏幕可以看。你把一张纸放进打字机里。钥匙卡上的每一个字母都连接在一个金属臂上，当你打字时，它就会伸出来在纸上涂上墨水! 如果你犯了错误，你必须重新开始一张纸或使用一滴特殊的白色颜料。为了掩盖你的错误。 这些打字机有数百个活动部件，很难修理。

It took people a long time to type anything with a typewriter. But, some people could type more than 120 words per minute on these old machines—with no mistakes! Today, most people can type about 60 words per minute on a computer. How fast can you type?

人们用打字机打字要花很长时间。但是，有些人在这些旧机器上每分钟可以打120多个字，而且没有错误! 今天。大多数人在电脑上每分钟能打60个字。你打字有多快?
