The new century is coming It can be predicted that life science and space science will make breakthrough progress in the century First of all , scientists will overcome incurable diseases with the same technology through gene transformation They can cultivate new animal species in the laboratory , even human life They can delay aging and prolong life They will establish permanent observation stations on the moon or other planets or stars , so that scientists can conduct in-depth research on the moon and other planets or stars Life mayHowever , the development of science will also realize some social problems How should we look at the people bred by genetic technology in the laboratory from an ethical point of view ? How can the police identify criminals from a group of people with the same DNA ? We will naturally encounter problem新世纪即将来临，可以预见，生命科学和空间科学将在世纪取得突破性进展。首先，科学家们将通过基因转化，用同样的技术攻克不治之症，他们可以在实验室培育出新的动物物种，甚至是人类的生命，它们可以延缓衰老，延长寿命，将在月球或其他行星或恒星上建立永久性观测站，以便科学家对月球和其他行星或恒星进行深入研究，极有可能在宇宙中的其他恒星中发现生命，或发现适合人类生存的行星或恒星。然而，科学的发展也将实现一些社会问题我们应该如何从伦理的角度看待实验室基因技术培育出来的人警察如何从一群 DNA 相同的人中辨认出罪犯我们在科学和社会发展中自然会遇到问题，我们应该准备迎接新的挑战。

Science and technology is the ability of people to understand nature and transform nature People use science and technology to transform the world , benefit mankind and promote social progress But on the other hand , excessive use of science and technology , will bring damage to mankind , is not conducive to the progress and development of human society

Life isn't about keeping It's not about how many friends you have or how accepted you Not about if you have plans this weekend or if you're It isn't about who you're dating, who you used to date, how many people you've dated, or if you haven't beem with anyone at It isn't about who you have It's not about It isn't about who your family is or how much money they have Or what kind of car you Or where you are sent to It's not about how beautiful or ugly you Or what clothes you wear, what shoes you have on, or what kind of music you listen It's not about if your hair is blonde, red, black, or brown or if your skin is too light or too Not about what grades you get, how smart you are, how smart everybody else thinks you are, or how smart standardized tests say you It's not about representing your whole being on a piece of paper and seeing who will "accept the written "LIFE JUST ISN'TBut, life is about who you love and who you It's about who you make happy or unhappy It's about keeping or betraying It's about friendship, used as a sanctity or a It's about what you say and what you mean, maybe hurtful, maybe about starting rumors and contributing to petty It's about what judgments you pass and And who your judgement arespread It's about who you've ignored with full control and It's about jealousy, fear, ignorance, and It's about carrying inner hate and love, letting it grow, and spreading But most of all, it's about using your life to touch or poison other people's hearts in such a way that could have never occurred Only you choose the way those hearts are affected, and those choices are what life's all about

With the development of science and technology, our side appeared a lot of new things,such as clone,The scientific invention of clone has become a hot topic among people,especially among the young and heated debates are right on their Now the cloning scientific has been used for many years to produce plants, it has brought us a lot of benefits but has created some serious problems as The benefit of cloning is cloning human organs or body parts , such as that if a parson in a traffic accident lost his arm or leg ,or someone get a serious heart disease and face danger ,he need a new body parts replace ,At this time we can use cloning technology copy a new parts of body to replace ,in the this way can be ensure that someone continue to live ,so that the clone is benefit for us Everything has two sides and cloning is not an exception,it has both advantages and On the contrary,most people are against of cloning technology been used in our life

I have a dream that I will become an Speak of invention, I can't help thinking of Lu Ban's saw, Zhang Heng's seismograph and Edison's electric light and so These inventions, great and magical, greatly changed the world, which makes me crazy about the scientific In our lives, garbage can be seen almost everywhere---on the road, in the park, in the , even on the tree, there are some "white pollution"; sometimes bad smell float in the Earth mother’face is becoming dirtier and dirtier, so is her Lots of natural disasters, that is the penalty our Earthmother impose to our human Thus, I want to invent a kind of Roberts that can "suck "all kinds of In this way, it gets rid of all the garbage in our life so as to return us fresh air, clean river and nice I sincerely believe that my dream will come true and our earth will be I will try my best to explore the wonders of science and achieve success of invention by my hard 汪凡懿 (汪凡懿_1) 大连开发区松林小学 去TA的个人空间看看

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。
