6、ed 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 separa
7、te 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 mans ear drum and the other to a piece of

9、they could be sent 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 searching 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: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
10、telegraph wires will be laid on to houses 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。The patent was given in 1876, but it was not until five days later that Bell sent his first telephone message to his a

13、d invaluable in the design of bridges.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 seventy- 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 searcher after practical solutions to improve the quality of everybodys 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。专心-专注-专业
