Nikola Tesla, a Serbian-American who emigrated to New York City in 1884, was a scientist and visionary who developed the basis for alternating current (AC) that most of us use today and pioneered numerous technologies that improve our everyday lives. Without his contribution to the AC electric power, we would be fifty years behind technologically than where we are today.
第一段: (尼古拉·特斯拉(Nikola Tesla)，一位於1884年移居往紐約的塞爾維亞裔美國人，是一個科學家與有遠見的人-開發了今日大多數的我們在使用的交流電(AC)的基礎，以及開拓/開創了許多改善我們日常生活的技術。(如果)沒有他的交流電電力貢獻，我們將落後我們所處的今日的技術50年。)

       In 1884, Tesla left Europe and worked for Thomas Edison, the developer of direct current (DC). It was said that Edison promised Tesla $50,000 to fix the problems with his DC system. When Tesla succeeded and demanded his reward, Edison claimed the offer was a joke, saying “When you become a full-fledged American, you will appreciate an American joke.” This prompted Tesla to quit and he ended up in a battle with Edison. Today, Tesla’s AC system is predominantly used to power most of the world’s electricity. DC motors are still used for some industrial machines, but often require more maintenance. 
第二段: (在西元1884年，特斯拉(Tesla)離開歐洲並為直流電(DC)的開發者-湯瑪斯·愛迪生(Thomas Edison)工作。據說愛迪生(Edison)答應給特斯拉(Tesla)5萬元美金修理好他的直流電系統的問題。當特斯拉(Tesla)成功了並要求他的報酬時，愛迪生(Edison)(卻)聲稱那個提議是個玩笑話，並說 "當你成為一個羽翼豐滿/毛長齊的美國人之時，你將會感謝這個美國玩笑。"這件事情促使了特斯拉(Tesla)辭職並且最終是以與愛迪生(Edison)的戰役告終(二人開戰到最後)。今日，特斯拉(Tesla)的交流電(AC)系統是佔據主導地位/主要地被使用來提供電力給全世界大部分的電力。直流電(DC)馬達/發電機仍使用於一些工業機器，但是卻時時需要更多的維修。)

         It is not just AC power that Tesla worked on. Motors, radios, X-rays, neon signs were advanced by his extraordinary mind. History often touts Italian entrepreneur Guglielmo Marconi as the inventor of radio, but actually he was using technology from seventeen of Tesla’s patents. The two inventors became embroiled in a patent war. In 1943, the United States Supreme Court revoked Marconi’s radio patents in favor of Tesla. Unfortunately, Tesla and Marconi had already passed away by the time the court handed down their decision.
第三段: (特斯拉(Tesla)從事/致力於研發的不只有交流電(AC)的電力。馬達/發電機、無線電/收音機、X-光/X-射線、霓虹燈告示牌也都是由他非凡的頭腦所推進的。歷史常常是吹捧/宣揚義大利企業家古列爾莫·馬可尼(Guglielmo Marconi)為無線電/收音機的發明者，但實際上/其實~他所使用的是取自於特斯拉(Tesla)的17項專利中的技術。這兩位發明者演變成捲入一場專利戰裡。於西元1943年，美國最高法院支持特斯拉(Tesla)而撤回/撤銷了馬可尼(Marconi)的無線電專利。(只不過)遺憾的是，(等)到了法院(總算是)正式宣布他們的判決時，特斯拉(Tesla)與馬可尼(Marconi)(卻)早已逝世。)

       Tesla also invented one of the world’s earliest remote control and was a pioneer of X-ray technology. He took some of the first X-ray images of the human body and was one of the first scientists to hypothesize that X-rays could be harmful. The brilliant inventor contributed to reusable energy as well. Nine out of the twelve patents used to build the world’s first hydroelectric station, erected at Niagara Falls, New York, belonged to Tesla. He helped pave the way toward clean energy because he understood the physics behind energy and what might be possible in the future.
第四段: (特斯拉(Tesla)也發明了世界最早的遙控器之一，以及是X-光/X-射線技術的先驅者。他率先拍下了一些人體的X-光圖像，並且(同時也是)最先提出假設X-光可能有害的科學家之一。這位才華洋溢的發明家也造就了可重複使用的能源。被使用來建造那豎立於紐約尼加拉瀑布的世界第一座水力發電站的12項專利中的9項專利是屬於特斯拉(Tesla)。他幫忙為清潔能源鋪了路，因為他了解到在能源背後的物理學並且(還知道)什麼是有可能被發生在未來。)

       Often referred to as “the man who invented the 20th century,” Tesla was involved in many more discoveries and creations. When he died in 1943, there was so(如此~) much interest in what he was working on that(以致於~) the Federal Bureau of Investigation (FBI) raided his hotel room within hours of his death. Experts say Tesla envisioned his inventions improving people’s lives. Indeed, his innovative ideas were milestones of technology. The great pioneer believed “Invention is the most important product of men’s creative brain.”
