Have you ever used a typewriter?If not,you've surely seen one.This useful
machine has a most interesting history.
Although you may think that the
typewriter is a modern invention,the idea goes as far back as the early 1700s.
It was then,in 1714,that England's Queen Anne granted Henry Mill the first
patent( 专利)for a machine that typed letters.Called An Artificial Machine or
Method For Impressing Letters,the machine remained just a design on paper.
Various other typing machines were invented over the next hundred years or
so.However,all of them had the same problem:they required more time to use
than writing the same material by hand.Things improved a little around 1829
when an American named William Butt invented a machine called the desired
letter.He also pressed a bar to link the paper.The machine printed letters
well,but it had a top speed of only five words a minute.
Finally,in 1874,
a more practical machine was introduced to the public.Invented by an American
Christopher Sholes and some of his companions,the machine was set up by E.
Remington and Sons and called the "Remington Model No.1 ".It was the first
typewriter to have the kind of typewriter keyboard we know today.
You may
have a look at the typewriter keyboard and wonder about the strange arrangement
of letters.As a matter of fact,the keys were so arranged to force typists to
type lower.Typing too fast caught the keys of Remington 1 pressed together.
They still follow this early arrangement of letters of the keyboard.

你用过打字机吗?即使没用过,你肯定也见到过.这一用途广泛的机器有着一个很有趣的历史.就算人们认为打字机是现代的发明,但打字机的理念却要追溯到1700年代（18世纪）.在1714年,英国女王安妮批准了Henry Mill 的一项专利,一台能够打出字母的机器,这台机器叫做“人造机器”或“刻字机”.然而这台机器仅仅是一个纸张上的设计图.
差不多在接下来的100多年里,各种不同类型的打字机被发明出来.然而,所有这些机器都存在着相同问题：书写相同的内容,使用打字机比用手写还要费时.直到1829年,一位叫William Burt的美国人发明了一种叫做“理想字母”的打字机,这种情况才稍有改善.他在打字机上安装了一个长条以连接纸张.这台机器的打字效果很好,但最快的速度也只是一分钟打5个字.
最后,在1874年,一种更实用的打字机向公众推出了.它是被一位叫Christopher Sholes以及他的同伴们共同发明的,该机器由E.雷明顿组装,并被命名为“雷明顿1型”.这就是第一台与现代的打字机有着同样健盘的打字机.也许在你看到这台打字机的健盘时,会对它奇怪的字母排例感到好奇.这种俳例真是太奇怪了,它与打字的速度和容易度并没有什么关联.事实上,把字母如此排例就是为了迫使打字员把打字速度放慢.过快的打字速度会使雷明顿1型的字母健挤压到一起.现在还在延用早期的这种字母排例顺序.
