Alexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA.小童话故事
亚历山大·格雷厄姆·贝尔1847年出生于苏格兰。但在他还小的时候，他家就搬到了美国的波士顿。
His mother was almost entirely deaf, so Alexander became interested in helping deaf people communicate and in deaf education.
他的母亲几乎全聋了，因此他有志于帮助聋人交流，并从事聋人教育事业。
This interest led him to invent the microphone. 这一爱好促使他发明了麦克风。
He found that by pressing his lips against his mother's forehead, he could make his mother understand what he was saying.
他发现他把嘴唇放在母亲的额头上，并以一定的方式来移动额骨，就可以使她听懂他所说的
话。
He believed that one should always be curious and his most famous saying was:
他认为一个人应该总是有好奇心理。他最有名的一句话是：
"Leave the beaten track occasionally and dive into the woods.
偶尔离开平路去寻求困境。
Every time you do you will be certain to find something that you have never en before.
每次当你这样做的时候，你一定会发现你从未见过的东西。
Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind.
跟踪下去，不断探索，不知不觉中，你就会发现某种值得思考的东西盘踞着你的头脑。
All really big discoveries are the result of thought." 所有真正伟大的发现都是思考的结果。
It was this exploring around problems and his dynamic spirit that led to his most famous invention - the telephone in 1876.
正是这种对问题的探索和富有活力的精神造就了他那最著名的发明——1876年的电话。
Bell never t out to invent the telephone and what he was trying to design was a multiple telegraph.
贝尔并非一开始就想要发明电话的，他本来想设计的东西是多路电报。
This original telegraph nt a message over distances using Mor code (a ries of dots tapped out along a wire in a particular order).
这种原始的电报是在一段距离中用莫尔斯电码传递信息（莫尔斯电码是通过电线发出的以特定的次序敲击出的一连串点划），
But only one message could go at a time. 但是这样只能一次发一个信息。
Bell wanted to improve it so that it could nd veral messages at the same time.
贝尔想改进电报通讯方式，以便同时能发出好几个信息。
He designed a machine that would parate different sound waves and allow different conversations to be held at the same time.
他设计了一种机器，以使声波分成不同的音调，从而有可能在同一时间里进行不同的通话。
But he found the problem difficult to solve.但是他发现这个问题很难解决。
One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass,
有一天做实验，他把一根干草的一端和一个聋子的耳鼓膜连接起来，另一端连接一块被烟熏过的玻璃。

Bell noticed that when he spoke into the ear, the straw drew sound waves on the glass.
贝尔发现，当他对着耳朵说话的时候，这根干草就把声波画在被烟熏过的玻璃上。

Suddenly he had a flash of inspiration.突然间他灵机一动，灵感来了。
If sound waves could be reproduced in a moving electrical current, they could be nt along a wire.
如果声波能够以连续运动的电波形式复制的话，那么声波就可以沿着导线传送出去了。
In arching to improve the telegraph, Bell had invented the first telephone!
在探求改进电报的过程中，贝尔发明了第一台电话机！
Bell was fully aware of the importance of his invention and wrote to his father:关于雪的诗句
贝尔完全懂得这项发明的重要性，他写信告诉他的父亲说：
"The day is coming when telegraph wires will be laid on to hous just like water or gas – and friends will talk to each other without leaving home."
这样的一天即将到来。到那时，电报线将会铺到各家各户，就像水和煤气通到各家
各户一样。朋友之间不必离开家就可以彼此通话了。
一篇写景的作文The patent was given in 1876, but it was not until five days later that Bell nt his first telephone message to his assistant Watson.
这项专利是1876年发布的，但是贝尔是在五天以后才跟他的助手华生通了第一次电话。
The words have now become famous:他说的话现在已成为名言了。
"Mr. Watson - come here - I want to e you." ―华生先生——到这儿来——我想见你。
Alexander Graham Bell was not a man to rest and he interested himlf in many other areas
of invention.
亚历山大·格雷厄姆·贝尔是个闲不住的人，他对许多其他领域的发明都感兴趣。
He experimented with helicopter designs and flying machines. 他试验直升飞机和飞行器。

While arching for a kite strong enough to carry a man into the air, Bell experimented putting triangles together and discovered the tetrahedron shape.
他寻找一种强度足以把人带上天空的风筝，与此同时，他又试着把三角形拼装在一起，因而发现了四面体。
Being very stable, it has proved invaluable in the design of bridges.
写老师这种四面体非常稳定，被证明是在桥梁设计中的无价之宝。
Bell was an inventor all his life.贝尔的一生都在发明创造。
He made his first invention at eleven and his last at venty- five.
他11岁时就有了第一项发明，而他的最后一项发明则是在他75岁高龄的时候。
Although he is most often associated with the invention of the telephone, he was indeed a continuing archer after practical solutions to improve the quality of everybody's life.
虽然人们常把他与电话的发明联系在一起，但是他的确是一位永不停息的探索家，不断
寻求着改善人们生活质量的途径。
