4、雷厄姆贝尔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。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。这一爱好促使他发明了麦克风。他发现他把嘴唇放到母亲的额头上，就可以使母亲听懂他所说的话。他认为一个人应当具有好奇心，他最著名的一句话是：“偶尔离开平路去寻求困境。当你这么做的时候，你一定会发现你从未见过的东西。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占据着你的头脑。所有真正伟大的发现都是思考的结果。”助读讲解 every time 是名词短语作连词，引导时间状语从句，相当于 whenever，意为“每次”。t
5、hat you have never seen before 是 that 引导的定语从句，修饰 something。before you know it可翻译成“不知不觉地”。It was this exploring around problems and his dynamic(充满活力的)spirit that led to his most famous inventionthe telephone in 1876.Bell never set out to invent the telephone and what he was trying to design was a mul
6、tiple telegraph.This original telegraph sent a message over distances using Morse code(a series of dots(点；小圆点)tapped(轻敲)out along a wire(电线)in a particular order)But only one message could go at a time.Bell wanted to improve it so that it could send several messages at the same time.He designed a ma
7、chine that would separate different sound waves and allow different conversations to be held at the same time.But he found the problem difficult to solve.One day as he was experimenting with one end of a straw(稻草；麦秆)joined to a deaf mans ear drum and the other to a piece of smoked glass，Bell noticed
8、 that when he spoke into the ear，the straw drew sound waves on the glass.Suddenly he had a flash of inspiration.If sound waves could be reproduce in a moving electrical current(电流)，they could be sent along a wire.In searching to improve the telegraph，Bell had invented the first telephone！正是这种对问题的探索和
9、富有活力的精神促成了他最著名的发明1876 年的电话。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。这种原始的电报用莫尔斯电码长距离传送信息(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)。但是这样一次只能发一个信息。贝尔想改进电报通讯方式，以便同时能发出好几个信息。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。但是他发现这个问题很难解决。有一天做实验，他把一根干草的一端和一个耳聋的人的耳鼓膜连接起来，另一端连接了一块被烟熏过的玻璃。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玻璃上。突然间他灵机一动，灵感来了。如果声波
10、能够以连续运动的电流形式复制的话，那么声波就可以沿着导线传送出去了。在探求改进电报的过程中，贝尔发明了第一台电话机！助读讲解 what he was trying to design 是 what 引导的主语从句。that would separate是 that 引导的定语从句，对 a machine加以修饰和限制。difficult to solve 是形容词短语作后置定语，相当于定语从句 that/which is difficult to solve。to solve 是动词不定式，用主动形式表达被动意义。Bell was fully aware of the importance o

13、arry a man into the air，Bell experimented putting triangles(三 角 形)together and discovered the tetrahedron(四 面体)shape.Being very stable(稳定的)，it has proved invaluable in the design of bridges.Bell was an inventor all his life.He made his first invention at eleven and his last at seventy-five.Although
14、he is most often associated(联系)with the invention of the telephone，he was indeed a continuingsearcher after practical solutions to improve the quality of everybodys life.贝尔完全意识到这项发明的重要性，他写信对他的父亲说：“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。”这项专利是 1876 年授予的，但是直到 5 天以后贝尔才跟他的助手华生通了第一次电话
15、。他说的话现在已成名言了：“华生先生到这儿来我想见到你。”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。他试验直升飞机和设计飞行器。他寻找一种强度足以把人带上天空的风筝，他又试着把三角形拼装在一起，因而发现了四面体。这种四面体非常稳定，被证明是在桥梁设计中的无价之宝。贝尔的一生都在发明创造。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。虽然人们常把他和发明电话联系起来，但是他的确是一名永不停息的探索家，不断寻求着改善人们生活质量的途径。助读讲解 when 引导定语从句，修饰 the day。is coming 是现在进行时表将来。Whil
