Ⅱ 關於小發明的英語作文
Good morning,everyone! Today I'm going to talk about inventions.
Inventions are created every day because people would like to make life easier.There are famous inventions like the TV and the bicycle.TV provides us with different kinds of information so that we can know more about the world.We watch entertainment programs to relax ourselves.Besides some learning programs help us with our study.
The bicycle is very useful,too. We go to school or work by bike.It's not expensive that most of us can afford it.It makes no pollution,which is good for our environment.What's more ,bicycle riding is a kind of exciting sports which is quite good for our health.
Although there have been many great inventions, I wish to invent a kind of pen which can help us write more quickly and neatly.When we meet problems in doing our homework or taking exams,it will tell us how to solve them.
That's all .Thank you very much.
早上好，大家！今天我要談論的發明。
發明創造的每一天，因為人們想使生活更容易。有著名的發明像電視和bicycle.tv為我們提供了不同的信息，以便我們可以更多地了解世界。我們看娛樂節目放鬆自己。除了一些學習計劃幫助我們學習。
自行車是很有用的，太。我們去上學或上班騎自行車。它不是昂貴的，我們大多數人可以負擔得起。它沒有污染，這是對我們的環境。更重要的是，騎自行車是一種刺激的運動，對我們的健康有很好的。
雖然有很多偉大的發明，我想發明一種筆，可以幫助我們更迅速而整齊地寫。當我們在做我們的家庭作業或考試的問題，它會告訴我們如何解決他們。
這是所有的。非常感謝你。

1、In modern life we have many inventions.Thesemachines are very useful.They can make things better and faster than people.A washing machine can help us wash clothes.We have more time to do that we want to doring this time.A printing machine prints a lot of books,newspapers and other things qiickly.Buses,bikes,cars,trains,planes and shipshelr us travel faster than before.The compter is wonderful machine.It is one of the most important inventions. Today it is used in many ways.It can store innformations and work out math problems millions of times faster than a person can.In a few years,the computer may touch the lives of everyone.Even people in faraway villages.
在現代生活中，我們有許多發明。這些都是很有用的。他們可以做的更好，比人快。洗衣機可以幫我們洗衣服。我們有更多的時間去做我們想干這一次。印刷機出版了大量的書籍，報紙和其他東西qiickly公共汽車，自行車。汽車，火車，飛機，和shipshelr我們游得更快。計算機是神奇的機器。它是最重要的發明之一。今天，它是用來在許多方面。它可以存儲innformations和解決數學問題的數百萬倍的人能更快。在幾年之內，計算機可能觸及每個人的生活。即使人在遙遠的村莊。
2、19世紀初，人們開始使用煤氣燈(瓦斯燈)，但是煤氣靠管道供給，一但漏氣或堵塞，非常容易出事，人們對於照明的改革，十分殷切。事實上，愛迪生為自己訂定了一個不可能的任務：除了改良照明之外，還要愛迪生發明的電燈創造一套供電的系統。 於是他和夢羅園的夥伴們，不眠不休的做了1600多次耐熱材料和600多種植物纖維的實驗，才製造出第一個炭絲燈泡，可以一次燃燒45個鍾頭。後來他更在這基礎上不斷改良製造的方法，終於推出可以點燃1200小時的竹絲燈泡。 19世紀80年代中期，愛迪生的電燈事業獲得了成功，這一成功比以往任何成就給他帶來的聲譽都大。在80年代中期以前，他很少有失誤，中期以後，盡管他也取得了很大成就，但失敗也是屢見不鮮的。愛迪生最不值得稱贊的行為之一就是他批評交流電，說它有副作用，可能造成死亡與損傷，但他未加具體說明。所以有人說，「像他這樣一個自己搞出了許多發明創造的人竟然對別人的新發明大加攻擊，這是很矛盾的事。」他反對使用交流電而贊成直流電，因而在一場激烈而固執的論戰中敗北。在這方面，反映出了愛迪生成為名人之後漸漸滋生的頑固守舊的缺點。
In the early nineteenth century, people began to use gas (gaslight), but the gas pipeline supply by a leak or blockage, very easy to have an accident, people for illumination of reform, very ardent. In fact, Edison for himself set the mission impossible: in addition to improve lighting, but also of Thomas Edison electric light Create a set of power supply system. And he and the dream LuoYuan buddies, sleepless do 1600 repeatedly heat-resistant material and more than 600 plant fiber experiment, only proced the first carbon wire bulb, can a burning 45 hours. Later he more on this basis, the method of continuous improvement manufacture can ignite 12 hours finally came out with the ZhuSi bulbs. The 19th century the 1980s, Edison electric light career succeeded, this success than any previous achievements brought him reputation. In the 1980s, before he had little mistake, intermediate later, although he has made great achievements, but also common occurance of failure. Edison's most not commendable actions is one of his criticism alternating current, say it has side effects, likely cause of death and injury, but he did not add details. So somebody said, "as he such a mess out many inventions that people about others' new invention saurday attack, this is very contradictory things." He opposes the use of alternating current and direct current, so the approve a fierce debate and stubborn in failure. In this respect, reflects the Edison became a celebrity after the stubbornness of started to foster old-fashioned shortcomings.
3、I will invent a time machine in the as it 's been my dream in my life. Time machine allows people to travel back in time to prevent disaster to happen. It also allows people to tavel into dinstant future to find out solution for Incurable illness including cancer and aids. However, this machine may be abused by people to create chaos in our world or even completely change our history. Therfore, security features are essential for my invention. The future invention of time machine will definately bring more advantages for human being.我會因為它是我的夢想在我的生活中，發明時間機器。時間機器允許人們旅行回來的時間來防止災難的發生。它也允許人們對tavel入dinstant未來發現無法治癒的疾病包括癌症和艾滋病的解決方案。然而，這台機器可能被濫用的人創造了我們的世界甚至完全改變我們的歷史的混亂。因此，安全的特點是我發明的關鍵。未來的時間機器肯定會為人類帶來更多的優勢。
Ⅳ 我現在在准備一篇英語作文的outline(大綱）， 是關於發明和instrial revolution的， 大概四百到五百字
1，2比較好寫。
11780年的一天，義大利解剖學家伽伐尼(Luigi Galvani）在做青蛙解剖時，兩手分別拿著不同的金屬器械，無意中同時碰在青蛙的大腿上，青蛙腿部的肌肉立刻抽搐了一下，彷彿受到電流的刺激，而如果只用一種金屬器械去觸動青蛙，就無此種反應。伽伐尼認為，出現這種現象是因為動物軀體內部產生的一種電，他稱之為「生物電」。
1799年，伏特把一塊鋅板和一塊銀板浸在鹽水裡，發現連接兩塊金屬的導線中有電流通過。於是，他就把許多鋅片與銀片之間墊上浸透鹽水的絨布或紙片，平疊起來。用手觸摸兩端時，會感到強烈的電流刺激。伏特用這種方法成功製成了世界上第一個電池「伏特電堆」。這個「伏特電堆」實際上就是串聯的電池組。
1836年，英國的丹尼爾對「伏特電堆」進行了改良，又陸續有效果更好的「本生電池」和「格羅夫電池」等問世。然而在當時，無論哪種電池都需在兩個金屬板之間灌裝液體，搬運很不方便，特別是蓄電池所用液體是硫酸，在挪動時很危險。
干電池的鼻祖在19世紀中期誕生。1860年，法國的雷克蘭士(George Leclanche）發明了碳鋅電池，這種電池更容易製造，且最初潮濕水性的電解液逐漸用黏濁狀類似糨糊的方式取代，於是裝在容器內時，「干」性的電池出現了。
1887年，英國人赫勒森(Wilhelm Hellesen）發明了最早的干電池。相對於液體電池而言，干電池的電解液為糊狀，不會溢漏，便於攜帶，因此獲得了廣泛應用。
Ⅳ 科學家發明電池的故事300字
電池的發明人伏打（1745～1827）是一位義大利的物理學家，伏打曾擔任帕維亞大學物理學教授。1745年2月18日伏打誕生於一個名叫科摩的義大利小城鎮。伏打從小對電學發生了興趣。1800年伏打用銅片和錫片中間夾有鹽水浸透的紙殼，製成了電池。後來又多次實驗發現，把各種金屬按著鋁、鋅、錫、鐵、銅、銀和金的順序排列時，每兩種金屬組成電池，則前面的金屬帶正電，而後面的金屬帶負電。這就是伏打所發現的「接觸電勢差系列。
他對已有的驗電器進行改造，製成了一種能夠測定微量電荷的驗電器。使用這種驗電器，伏打反復驗證各種金屬產生的電能，發現了起電序列，製成了電堆，使人類首次獲得了穩定而持續的電流，開創了動電研究新時代。使用伏打電堆，他證實了兩種不同性質的金屬相互接觸時，其接觸表面就會出現異性電荷，同時其表面之間還會產生接觸電位差，這種電位差的大小隨兩相接觸的金屬而異。同時還證實了所有的金屬導體，都能排成一個序列，序列中的任何一種金屬與後面一種金屬相接觸時，前者帶正電，後者帶負電，伏打據此排列出了世界上第一個電氣元素表。1800年伏打將其長期研究結果在英國皇家學會學報上發表，使全世界都知道了伏打和他的電堆，第二年拿破崙在巴黎看了他的電池表演後，封他為伯爵。人們為了紀念他，用他的名字「伏」命名了電壓單位。

Ⅵ 關於電池的英文資料
History of the battery
The first battery was invented in 1800 by Alessandro Volta. Although it was of great value for experimental purposes, its limitations made it impractical for large current drain. Later batteries, starting with John Frederic Daniell's wet cell in 1836, provided more reliable currents and were adopted by instry for use in stationary devices, particularly in telegraph networks where, in the days before electrical distribution networks, they were the only practical source of electricity. These so-called wet cells used liquid electrolytes, and were thus prone to leaks and spillage if not handled correctly. Some, like the gravity cell, could only function in a certain orientation. Many used glass jars to hold their components, which made them fragile. These practical flaws made them unsuitable for portable appliances. Near the end of the 19th century, the invention of dry cell batteries, which replaced liquid electrolyte with a paste, made portable electrical devices practical.
