6、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。”It was this exploring around problems and his dynamic spirit that led to his most famous invention the telephone in 1876. Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. This original telegraph sent a message over
7、 distances using Morse code (a series of dotstapped out along a wire 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 machine that would separate different sound waves and allow different
8、 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 strawjoined to a deaf mans ear drum and the other to a piece of smoked glass, Bell noticed that when he spoke into the ear, the straw drew sound waves on the gla

12、明1876年的电话的。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。如果声波能够以连续运动的电流形式复制的话
13、，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！Bell was fully aware of the importance of his invention and wrote to his father：“Thedayiscomingwhentelegraphwireswillbelaidontohousesjustlikewaterorgas andfriendswilltalktoeachotherwithoutleavinghome.”The patent was given in 1876, but it was not until five d
14、ays later that Bell sent his first telephone message to his assistant Watson. The words have now become famous：“MrWatson comehere Iwanttoseeyou.”Alexander Graham Bell was not a man to rest and he interested himself in many other areas of invention. He experimented with helicopter designs and flying
15、machines. While searching for a kite strong enough to carry a man into the air, Bell experimented putting triangles together and discovered the tetrahedron shape. Being very stable， 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 seventyfive. Although he is most often associated with the invention of the telephone， he was indeed a continuing searcher after practical solutions to improve the quality of everybodys life. be aware of意识到when引导定语从句
