Invented the first must have good knowledge， there will be a degree of hope， I read a lot of books， consulting a lot of teacher， after communication with students， produced a can sweep the floor time adsorption of other devices on the ground， so mother later don't need so
三篇收集的作文，望采纳1、In modern life we have many Thesemachines are very They can make things better and faster than A washing machine can help us wash We have more time to do that we want to doduring this A printing machine prints a lot of books，newspapers and other things Buses，bikes，cars，trains，planes and shipshelr us travel faster than The compter is wonderful It is one of the most important Today it is used in many It can store innformations and work out math problems millions of times faster than a person In a few years，the computer may touch the lives of Even people in faraway 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 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 And he and the dream LuoYuan buddies， sleepless do 1600 repeatedly heat-resistant material and more than 600 plant fiber experiment， only produced the first carbon wire bulb， can a burning 45 Later he more on this basis， the method of continuous improvement manufacture can ignite 12 hours finally came out with the ZhuSi The 19th century the 1980s， Edison electric light career succeeded， this success than any previous achievements brought him In the 1980s， before he had little mistake， intermediate later， although he has made great achievements， but also common occurance of 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 So somebody said， "as he such a mess out many inventions that people about others' new invention saurday attack， this is very contradictory " He opposes the use of alternating current and direct current， so the approve a fierce debate and stubborn in In this respect， reflects the Edison became a celebrity after the stubbornness of started to foster old-fashioned 3、I will invent a time machine in the as it 's been my dream in my Time machine allows people to travel back in time to prevent disaster to It also allows people to tavel into dinstant future to find out solution for Incurable illness including cancer and However， this machine may be abused by people to create chaos in our world or even completely change our Therfore， security features are essential for my The future invention of time machine will definately bring more advantages for human 我会因为它是我的梦想在我的生活中，发明时间机器。时间机器允许人们旅行回来的时间来防止灾难的发生。它也允许人们对tavel入dinstant未来发现无法治愈的疾病包括癌症和艾滋病的解决方案。然而，这台机器可能被滥用的人创造了我们的世界甚至完全改变我们的历史的混乱。因此，安全的特点是我发明的关键。未来的时间机器肯定会为人类带来更多的优势。

Good morning，everyone! Today I'm going to talk about Inventions are created every day because people would like to make life There are famous inventions like the TV and the TV provides us with different kinds of information so that we can know more about the We watch entertainment programs to relax Besides some learning programs help us with our The bicycle is very useful， We go to school or work by It's not expensive that most of us can afford It makes no pollution，which is good for our
What's more ，bicycle riding is a kind of exciting sports which is quite good for our Although there have been many great inventions， I wish to invent a kind of pen which can help us write more quickly and When we meet problems in doing our homework or taking exams，it will tell us how to solve That's all Thank you very much
早上好，大家！今天我要谈论的发明。发明创造的每一天，因为人们想使生活更容易。有著名的发明像电视和v为我们提供了不同的信息，以便我们可以更多地了解世界。我们看娱乐节目放松自己。除了一些学习计划帮助我们学习。自行车是很有用的，太。我们去上学或上班骑自行车。它不是昂贵的，我们大多数人可以负担得起。它没有污染，这是对我们的环境。更重要的是，骑自行车是一种刺激的运动，对我们的健康有很好的。虽然有很多伟大的发明，我想发明一种笔，可以帮助我们更迅速而整齐地写。当我们在做我们的家庭作业或考试的问题，它会告诉我们如何解决他们。这是所有的。非常感谢你。
