⑶ 英語作文,你認為最好的發明是電,為什麼
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.

愛迪生 一生只上過三個月的小學,他的學問是靠母親的教導和自修得來的。他的成功,應該歸功於母親自小對他的諒解與耐心的教導,才使原來被人認為是低能兒的愛迪生,長大後成為舉世聞名的「發明大王」。
愛迪生從小就對很多事物感到好奇,而且喜歡親自去試驗一下,直到明白了其中的道理為止。長大以後,他就根據自己這方面的興趣,一心一意做研究和發明的工作。他在新澤西州建立了一個實驗室,一生共發明了電燈、電報機、留聲機、電影機、磁力析礦機、壓碎機等等總計兩千餘種東西。愛迪生的強烈研究精神,使他對改進人類的生活方式,作出了重大的貢獻。
「浪費,最大的浪費莫過於浪費時間了。」 愛迪生常對助手說。「人生太短暫了,要多想辦法,用極少的時間辦更多的事情。」
一天,愛迪生在實驗室里工作,他遞給助手一個沒上燈口的空玻璃燈泡,說:「你量量燈泡的容量。」他又低頭工作了。
過了好半天,他問:「容量多少? 」他沒聽見回答,轉頭看見助手拿著軟尺在測量燈泡的周長、斜度,並拿了測得的數字伏在桌上計算。他說:「時間,時間,怎麼費那麼多的時間呢?」愛迪生走過來,拿起那個空燈泡,向裡面斟滿了水,交給助手,說:「裡面的水倒在量杯里,馬上告訴我它的容量。」
助手立刻讀出了數字。
愛迪生 說:「這是多麼容易的測量方法啊,它又准確,又節省時間,你怎麼想不到呢?還去算,那豈不是白白地浪費時間嗎?」
助手的臉紅了。
