Unit3 ALEXANDER GRAHAM BELL 亚历山大·格雷厄姆·贝尔
Alexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA. 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 seen 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 set 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 sent a message over distances using Morse code (a series 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 send several 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 separate 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。追问疑？不是这篇，是THE PROBLEM OF THE SNBKES追答
