科學(xué)英語演講短文
英語演講短文帶翻譯：Many scientists, from their earlier work, know enough to make good guesses on the solutions to the problems they are working on.
許多科學(xué)家從他們?cè)缙诘墓ぷ髦蟹e累了很多知識(shí),足以對(duì)他們鉆研的問題的解決方案做出很好的猜想。
In making new discoveries, they may use trial-and-error, they may use past experience, duanwenw.com or they may try to find out what others have discovered. They may come up with new experiments and new ways of testing their results. Scientists have to train themselves to use their brains efficiently; that is, they train themselves to think.
在探索新事物的時(shí)候,他們可以采用反復(fù)試驗(yàn)的方法,可以利用過去的經(jīng)驗(yàn),或者是借鑒別人的探索成果。他們可以設(shè)計(jì)出新的試驗(yàn),研究出新的方法來檢驗(yàn)他們的結(jié)果�？茖W(xué)家們得訓(xùn)練自己有效地使用大腦；也就是說,訓(xùn)練自己去思考。
For example, when Thomas A. Edison was trying to make an electric lamp, he needed a substance for the filament* inside the bulb that would glow brightly without burning up quickly. He tried more than a thousand different filaments before he found one that he could use. After each trial he thought about how the new substance had behaved. He kept notes and compared results. After he had experimented for a long time, someone asked Mr. Edison if he was ever discouraged by the time they thought he had wasted. He replied, "I have not been wasting time. I have just found a thousand materials that won’t work. Now I can look for others that will." Edison’s statement is important. Above all, scientists demand to know when and where they are wrong. A good question to ask in science is not, "Am I right? "but, "Am I wrong?"
例如,當(dāng)托馬斯·阿爾瓦·愛迪生在發(fā)明電燈過程中,他需要一種既能發(fā)出明亮的光又不會(huì)很快燒毀的材料來作燈泡里的燈絲。英語短文他嘗試了一千多種不同的燈絲后才找到一種適合的材料。每一次嘗試之后,他都在思索新的材料該如何發(fā)揮作用。他不斷地記筆記,比較結(jié)果。經(jīng)過很長時(shí)間的實(shí)驗(yàn)之后,有人問愛迪生,如此浪費(fèi)時(shí)間他難道不感到沮喪？愛迪生回答說:"我并沒有浪費(fèi)時(shí)間。我已經(jīng)找出有一千種材料不管用。現(xiàn)在我可以尋找其他材料了。"愛迪生的話非常重要。最重要的`是,科學(xué)家應(yīng)該知道他們是在何時(shí)、何處錯(cuò)了。在科學(xué)上,一個(gè)問得高明的問題并不是"我對(duì)不對(duì)？"而是"我錯(cuò)沒錯(cuò)？"
Scientists spend many years studying and training themselves to use their brains and the tools of investigation. duanwenw.com They also use each other’s work. Isaac Newton, the famous British scientist who lived over 300 years ago, once said hhe saw further than others because he stood on the shoulders of giants.
科學(xué)家經(jīng)過多年的研究,訓(xùn)練自己使用大腦和各種研究手段。他們也相互借鑒研究成果。生活在300多年前的英國著名科學(xué)家艾薩克·牛頓就曾說過,他之所以比別人看得更遠(yuǎn),是因?yàn)樗驹诰奕说募绨蛏稀?/p>
