⑶ 英语作文,你认为最好的发明是电，为什么
The telephone is an instrument that converts voice and sound signals into electrical impulses for transmission by wire to a different location,where another telephone receives the electrical impulses and turns them back into recognizable sounds.In 1875,Alexander Graham Bell built the first telephone that transmitted electrically the human voice.
When Bell began experimenting with electrical signals,the telegraph had been an established means of communication for some 30 years.Although a highly successful system,the telegraph,with its dot-and-dash Morse code,was basically limited to receiving and sending one message at a time.Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time.Although the idea of a multiple telegraph had been in existence for some time,Bell offered his own musical or harmonic approach as a possible practical solution.His "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.

爱迪生 一生只上过三个月的小学，他的学问是靠母亲的教导和自修得来的。他的成功，应该归功于母亲自小对他的谅解与耐心的教导，才使原来被人认为是低能儿的爱迪生，长大后成为举世闻名的“发明大王”。
爱迪生从小就对很多事物感到好奇，而且喜欢亲自去试验一下，直到明白了其中的道理为止。长大以后，他就根据自己这方面的兴趣，一心一意做研究和发明的工作。他在新泽西州建立了一个实验室，一生共发明了电灯、电报机、留声机、电影机、磁力析矿机、压碎机等等总计两千余种东西。爱迪生的强烈研究精神，使他对改进人类的生活方式，作出了重大的贡献。
“浪费，最大的浪费莫过于浪费时间了。” 爱迪生常对助手说。“人生太短暂了，要多想办法，用极少的时间办更多的事情。”
一天，爱迪生在实验室里工作，他递给助手一个没上灯口的空玻璃灯泡，说:“你量量灯泡的容量。”他又低头工作了。
过了好半天，他问:“容量多少? ”他没听见回答，转头看见助手拿着软尺在测量灯泡的周长、斜度，并拿了测得的数字伏在桌上计算。他说:“时间，时间，怎么费那么多的时间呢?”爱迪生走过来，拿起那个空灯泡，向里面斟满了水，交给助手，说：“里面的水倒在量杯里，马上告诉我它的容量。”
助手立刻读出了数字。
爱迪生 说:“这是多么容易的测量方法啊，它又准确，又节省时间，你怎么想不到呢？还去算，那岂不是白白地浪费时间吗?”
助手的脸红了。
