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.
在现代生活中,我们有许多发明。这些都是很有用的。他们可以做的更好,比人快。洗衣机可以帮我们洗衣服。我们有更多的时间去做我们想干这一次。印刷机出版了大量的书籍,报纸和其他东西qiickly公共汽车,自行车。汽车,火车,飞机,和shipshelr我们游得更快。计算机是神奇的机器。它是最重要的发明之一。今天,它是用来在许多方面。它可以存储innformations和解决数学问题的数百万倍的人能更快。在几年之内,计算机可能触及每个人的生活。即使人在遥远的村庄。
2、19世纪初,人们开始使用煤气灯(瓦斯灯),但是煤气靠管道供给,一但漏气或堵塞,非常容易出事,人们对于照明的改革,十分殷切。事实上,爱迪生为自己订定了一个不可能的任务:除了改良照明之外,还要爱迪生发明的电灯创造一套供电的系统。 于是他和梦罗园的伙伴们,不眠不休的做了1600多次耐热材料和600多种植物纤维的实验,才制造出第一个炭丝灯泡,可以一次燃烧45个钟头。后来他更在这基础上不断改良制造的方法,终于推出可以点燃1200小时的竹丝灯泡。 19世纪80年代中期,爱迪生的电灯事业获得了成功,这一成功比以往任何成就给他带来的声誉都大。在80年代中期以前,他很少有失误,中期以后,尽管他也取得了很大成就,但失败也是屡见不鲜的。爱迪生最不值得称赞的行为之一就是他批评交流电,说它有副作用,可能造成死亡与损伤,但他未加具体说明。所以有人说,“像他这样一个自己搞出了许多发明创造的人竟然对别人的新发明大加攻击,这是很矛盾的事。”他反对使用交流电而赞成直流电,因而在一场激烈而固执的论战中败北。在这方面,反映出了爱迪生成为名人之后渐渐滋生的顽固守旧的缺点。
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.

Ⅳ 我现在在准备一篇英语作文的outline(大纲), 是关于发明和instrial revolution的, 大概四百到五百字
1,2比较好写。
11780年的一天,意大利解剖学家伽伐尼(Luigi Galvani)在做青蛙解剖时,两手分别拿着不同的金属器械,无意中同时碰在青蛙的大腿上,青蛙腿部的肌肉立刻抽搐了一下,仿佛受到电流的刺激,而如果只用一种金属器械去触动青蛙,就无此种反应。伽伐尼认为,出现这种现象是因为动物躯体内部产生的一种电,他称之为“生物电”。
1799年,伏特把一块锌板和一块银板浸在盐水里,发现连接两块金属的导线中有电流通过。于是,他就把许多锌片与银片之间垫上浸透盐水的绒布或纸片,平叠起来。用手触摸两端时,会感到强烈的电流刺激。伏特用这种方法成功制成了世界上第一个电池“伏特电堆”。这个“伏特电堆”实际上就是串联的电池组。
1836年,英国的丹尼尔对“伏特电堆”进行了改良,又陆续有效果更好的“本生电池”和“格罗夫电池”等问世。然而在当时,无论哪种电池都需在两个金属板之间灌装液体,搬运很不方便,特别是蓄电池所用液体是硫酸,在挪动时很危险。
干电池的鼻祖在19世纪中期诞生。1860年,法国的雷克兰士(George Leclanche)发明了碳锌电池,这种电池更容易制造,且最初潮湿水性的电解液逐渐用黏浊状类似糨糊的方式取代,于是装在容器内时,“干”性的电池出现了。
1887年,英国人赫勒森(Wilhelm Hellesen)发明了最早的干电池。相对于液体电池而言,干电池的电解液为糊状,不会溢漏,便于携带,因此获得了广泛应用。
Ⅳ 科学家发明电池的故事300字
电池的发明人伏打(1745~1827)是一位意大利的物理学家,伏打曾担任帕维亚大学物理学教授。1745年2月18日伏打诞生于一个名叫科摩的意大利小城镇。伏打从小对电学发生了兴趣。1800年伏打用铜片和锡片中间夹有盐水浸透的纸壳,制成了电池。后来又多次实验发现,把各种金属按着铝、锌、锡、铁、铜、银和金的顺序排列时,每两种金属组成电池,则前面的金属带正电,而后面的金属带负电。这就是伏打所发现的“接触电势差系列。
他对已有的验电器进行改造,制成了一种能够测定微量电荷的验电器。使用这种验电器,伏打反复验证各种金属产生的电能,发现了起电序列,制成了电堆,使人类首次获得了稳定而持续的电流,开创了动电研究新时代。使用伏打电堆,他证实了两种不同性质的金属相互接触时,其接触表面就会出现异性电荷,同时其表面之间还会产生接触电位差,这种电位差的大小随两相接触的金属而异。同时还证实了所有的金属导体,都能排成一个序列,序列中的任何一种金属与后面一种金属相接触时,前者带正电,后者带负电,伏打据此排列出了世界上第一个电气元素表。1800年伏打将其长期研究结果在英国皇家学会学报上发表,使全世界都知道了伏打和他的电堆,第二年拿破仑在巴黎看了他的电池表演后,封他为伯爵。人们为了纪念他,用他的名字“伏”命名了电压单位。

Ⅵ 关于电池的英文资料
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.
