满分英语范文3：一项有用的发明
Telephone is an instrument that converts sound and sound signals into electrical pulses and transmits them to different places through wires. When bell began to test electrical signals, Alexander Graham Bell made the first telephone to transmit human voice electronically. Telegraph has become an established means of communication.
Although telegraph is a very successful system, it has many advantages The Dow Morse code is basically limited to receiving and sending one message at a time. Bell's extensive understanding of the nature of sound and his understanding of music enabled him to speculate on the possibility of transmitting multiple messages simultaneously on the same wire. Although the idea of multiple telegrams had existed for some time, bell proposed his own musical or harmonic method as a workable solution, and his "harmonic telegraph" was based on the principle that if notes or letters The tone of the horn is different, and several notes can be sent along the same wire at the same time.

电话是一种将声音和声音信号转换成电脉冲，通过电线传输到不同地点的仪器，亚历山大·格雷厄姆·贝尔在贝尔开始试验电信号的时候，制造了第一部以电子方式传输人类声音的电话，电报已经成为一种既定的通讯手段，尽管电报是一种非常成功的系统，它有着多道莫尔斯电码，基本上只限于一次接收和发送一条信息。贝尔对声音本质的广泛了解和对音乐的理解使他能够推测在同一条电线上同时传送多条信息的可能性，尽管多重电报的想法已经存在了一段时间，贝尔提出了他自己的音乐或和声方法作为一种可行的解决方案，他的“谐波电报”是基于这样一个原则：如果音符或信号的音调不同，几个音符可以同时沿着同一根电线发送。
