我说,是科技的发展推动了人类的进程,是科技的发展才使人类有着这崭新又美好的生活。纵观千古,哪朝哪代不是重视科技的发展? 科技发展是强国之路,科技发展是中华民族进步的第一动力,没有科学,我们哪来的今天的幸福生活?没有科技,我们哪来的舒适的物质生活与精神享受?没有科技的进步,我们哪能吃到杂交二号?我们哪能穿上全棉衣服,哪能住进高楼大厦? 科技发展利大还是弊大?当然是利大!中华文明八千年历史文明就是铁证如山,历史每时每刻都在改变,科技每时每刻都在发展。如果是弊端大于利的话,那人类为什么都还不约而同的选择了进步?只有进步才能使明天更美好! 一个人不进步是可悲的,一个国家不进步是没落的,一个世界不进步是黑暗的。只要在不断的进步中,人类的生活才可以得到升华。上天给予了人类一颗聪慧的大脑,一双勤劳的双手,人类没有坐享其成,而是选择了不断进步,几千年来,从马车变成了轿车、火车、飞机;从煤油灯变成了白炽灯、霓虹灯、节能灯;从海角天涯变成了近在咫尺、视频聊天、鼠标一点尽知天下事。 所有人的不懈努力,刻苦钻研,我们今天的日子是有多少辛勤的科学家们用智慧甚至生命换来的。因为法拉第,我们生活的周围才充满了各种各样的电器;因为达尔文、因为孟德尔,我们才可以更好地了解自己,认识自己;因为扁鹊,因为华佗,因为李时珍,我们的生命才能得到保障。我们的平均寿命比古代提高了30岁,看望亲友甚至不用出家门,这不都是科学发展给我们带来的好处吗? 所以说,科技改变历史,我们探讨科技的发展利大还是弊大是不需要质疑的,因为就是利大!利大!利大!科技改变历史, 是科技发展救了我们,是科学把我们从水深火热的年代拯救了出来。科技改变历史,知识改变命运。我们跨入了21世纪,跨入了一个充满高科技的时代。科学改变了我们的生活,科学改变了我们的命运。“ 科技发展利大于弊,这是一个亘古不变的主题!

科技论文按照研究方法不同,科技论文可分理论型、实验型、描述型三类,理论型论文运用的研究方法是理论证明、理论分析、数学推理,用这些研究方法获得科研成果;实验型论文运用实验方法,进行实验研究获得科研成果;描述型论文运用描述、比较、说明方法来写比较好。
记得在小学的时候,曾在科学小报刊上看见过一个问题:以下哪种物品在加油站产生爆炸的可能性最大?1。手机2。尼龙衣。当时的我毫不犹豫就选择了手机,因为人们都说加油站不打手机,而至于尼龙衣就没怎么在意,况且那只是一件衣服而已,并不会有什么的。直到在有一天在电视上看《流言终结者》时才发现,原来手机并不会引起爆炸。而电视上的实验是这样的,首先他们先找来一张桌子,在桌子上洒下许多油,然后在带有油的桌子上放了4部手机,接着就离开那里到50M左右的地方。好了,第一个实验的准备工作就已经完成了。下面,4位工作人员同时拨打电话,远远的就能听见电话的铃声,却并没有发生爆炸。也许有人会问震动呢,震动+声音呢等等什么什么的,都不会引起爆炸,这是因为所谓的手机来电产生火花进而引爆弥散在空气中的油汽,只是理论上的推测,只有在极其严苛的条件在才有可能发生,而现实中是不可能发生的。但是如果是尼龙衣的话就有可能不一样了。接下来他们又做了另一个实验,来证明尼龙衣会产生爆炸。首先,他们同样是在桌子上洒满油,接下来,把一根很长的电线的一头固定在带有油的桌子上,接着将线拉倒离桌子90M左右的地方,然后,让一名工作人员穿上尼龙衣。这样,第二个实验的准备工作也已经完成了。接下来,那位工作人员就用左手拿着电线,用右手就在衣服上进行强烈的上下摩擦,摩擦一会儿后,就将右手的食指伸到电线的一头处,从电视上就能看到从食指上传到电线头处的电流。过了一秒,桌子那边发生了猛烈的爆炸。而其原因是尼龙衣属于化纤产品,一些摩擦就很容易产生静电,所以在穿尼龙衣去加油站是很不安全的。(第一次写,可能有错误或者重复)
对于生物能源,我们能做什么?自人类迈进二十一世纪以来,开发新能源成为全世界解决能源问题的共同出路。与化石燃料相比,新能源具有可再生、对环境友好等特点,更符合人类可持续发展的目标。其中,太阳能、风能、地热能、水能和潮汐能,是开发较早的新能源,已在实际生产生活中发挥了重要作用。曾一度被人们看好的核能,有着极高的能量值,可是其高额的研究经费和潜在的巨大危害,令世界大多数国家望而却步。而作为新能源中“排行”靠后的生物能源,却在最近几年内忽然人气锐增,势如破竹,被看作是“新能源家族中可实现度最高的未来能源”。那么究竟何谓生物能源呢,它又有哪些优势呢? 生物能源主要是指在生物体(尤为植物)内,经一系列化学反应所释放出的能源。其实,世界上90%的能源消耗来自植物光合作用所积累的能源,比如地球演变的历史上所积累的矿物能源(煤、石油、天然气,因为它们是堆积在一起的有机物经地质作用形成的),但总有一天矿物能源会消耗殆尽。能源危机威胁着人类的发展。所以发展可再生能源,尤其是利用植物光合产物转化成便于利用的能源,引起了全球的广泛关注。人类利用生物能源,实质是将植物通过光合作用固定的碳的能量释放出来。它的好处在于: 一、中性的碳循环,即无温室效应;二、生物再生的能源有助于克服化石能源供应的萎缩。并且,发展生物能源不仅可以解决资源、环境的问题,还可以带动农业产业的发展,实现环境与经济效应的双赢。 我国是粮食大国,同样也是资源匮乏的国家,发展生物能源十分符合我国国情。对此农业部成立了生物质工程中心,目的是加强农业生物质技术研究,在生物能源的开发等方面取得突出进展,并使我国在未来达到国际先进水平。与此同时,国内的众多科研院所也纷纷加入研发行列,试图开拓出自己的道路。巴西、美国等利用玉米淀粉转化成酒精已经取得很大成效。但是就世界上大多数国家和地区而言,不可以用有限的耕地去发展新的能源产业。所以利用荒地种植野生、半野生的能源植物已是大家认同的发展方向。另外,与某些国家采用把玉米、甘蔗转化成乙醇,或是从油料作物中提取生物柴油不同,我们国家把目光放在了更为高效的纤维素上。 中学生科技网 ]纤维素是植物的木质部分,是地球数量最大的植物积累的产物,植物从太阳获取的绝大部分能量也都储存于其中。所以人类一旦掌握了释放出存储在纤维素中能量的技术,能源危机便可迎刃而解。在北京市科技俱乐部组织的活动中,我有幸与北京大学生命学院的老师交谈,并聆听纤维素技术。我了解到纤维素的降解和转化是十分关键的步骤,也是巨大的难点。纤维素犹如植物坚硬的骨架,因此它远比淀粉类物质难分解。而突破口是找到合适的能高效分解纤维素的酶。在这方面生物又给了我们很好的启示:牛吃的是充满纤维素的草,却能够胜任拉车、耕田的重活。牛胃的反刍作用,其中微生物产生的纤维素酶都是很值得我们去模拟的。我们的课外科技活动就从这里开始,从分离和改良纤维素酶基因开始。而从另一个角度,我们还可以通过提高植物体内的纤维素含量,来提高转化效率,降低成本。天然的甜高梁、柳枝稷是目前已知的高纤维素含量植物,而通过对它们进行转基因处理,我们能从单位植株中获得更多的纤维素。 生物能源的开发与生物技术、基因工程密不可分。北大的老师向我讲述了基因工程在培育能源植物中的作用。其中包括促进光能产物的积累,促进采收后纤维素的降解,以及要使能源植物在缺水的环境中生长,要使这些植物耐受低温、增加一年中光能转化的时间。这些都是可以通过基因操作技术来实现。这些工作正是我们这一代人明天要做的事情。今天,我们要多学习这方面的高新技术知识。作为当代的青少年,我们需要放眼世界,密切关注生态环境和资源问题。过去,我们曾开展节水宣传、参与植树造林,为美化环境做出贡献。而现在我们要身体力行,加入到开发、宣传新能源的行列中。比如,我们可以在实验田里学农劳动,负责原料作物的种植和养护;有组织地进行野外考察,研究各种作物的成分及价值,提供给有关部门。或者科学合理地运用已有的知识,为增强农作物的环境适应性、解决荒漠化问题积极献言献策。我们还可以在学校内做培养微生物、植物的组织培养等实验,提高对生物工程技术的认识水平;加入青少年科技俱乐部,进入科研院所,与导师合作研究相关课题。或者是在学校、社区中宣传生物能源的使用前景…… 总之,有无数活动与创意等待我们去实施。在这个过程中,不但能丰富自己的文化知识,还可以提高科学素养,锻炼能力!其实,我们的力量并不微小。只要我们报有一颗热爱科学的心,将热情与智慧投入其中,就会获得意想不到的收获。而我们的家园,也必将在你我的行动中,变得越来越美丽!

本文来源:996论文网本文是一篇论文写作,科技小论文有时也称“实验报告”,是学生对研究的问题,特定设计的方案,经过反复实验,对获取的材料和数据进行分析、综合得出结论而写出的文章。下面我们一起来看看大学生科技小论文怎么写。一、选好课题撰写科技小论文,首先要考虑写什么,也就是课题的选择。选择课题是写好论文的关键。要注意以下原则:价值原则,即选题的理论价值和实用价值。要对其他的同学有启发、指导和参考的意义;可行原则,指主观和客观条件的可能性,即撰稿者个人的专业知识、理论修养、知识面、手头资料、实验条件、周围环境,不可贪大求深,应该量力而行;新颖原则,指课题应是他人未曾研究或研究过但未解决或完全解决,要注意“文贵创新”二、拟定题目文题如目,好的题目能够叫人拍案叫绝,一眼难忘。它好似推销产品的广告词,对吸引读者起着关键作用。好的科技小论文题目要讲求三个字:准、小、新。准,指的是题目要用精练的文字将论文内容确切的揭示出来。如某位同学撰写的科技小论文的题目是《肥皂的去污原理和最佳洗衣浓度》,一看题目,就可以知道 论文阐述的内容,一目了然。小,指的是题目的角度小。角度小,就具有较好的指向性,文章的思路随之明朗,容易写得集中、紧凑。题目过宽,往往由于我们投入研究的精力少,范围窄,专业知识不深,而难以驾驭。如某位学生撰写的科技小论文的题目是《静电除尘黑板擦的研究与制作》,题目小且具体,学生可以作深刻的阐述。新,指的是力求在题目中透露出新鲜的立意。选题新鲜,才有阅读价值。没有独特的见解,没有新的发现,即使表达再好,论证再有力,也是瞎子点灯白费蜡。三、写好开篇文章开头处于定调的特殊位置,历来为写作者们重视。古人云:“若起不得法,则杂乱浮泛”开头部分虽短,却是全篇的有机组成部分,提示作者的思绪和对众多材料的截取,因此落笔之前必须对全篇有总体把握。科技小论文的开头,不一而足,并无固定的格式,但却有章法可循,这就需要对各种开头的技法细加领悟,根据写作实际灵活运用。1、例题引路法写作科技小论文,开篇引题,显示了研究问题的实在性,激发读者顺藤摸瓜的愿望。如某同学撰写的《一道容易解错的力学题》一文,作者开头就摆出了一道同学们很熟悉而又容易出错的力学题,并将错误的解答过程陈述给读者,引起读者的强烈的兴趣,而急于读完全文,以知道这道题究竟错在何处。2、揭示背景法将研究的问题,放置到当前社会经济发展的大环境和大背景下,让读者在较高的层次体味其研究的意义乃至方向性。如《乡镇工业环境污染防治对策》一文是这样开头的:“改革开放以来,乡镇企业迅速崛起和蓬勃发展创造了大量的物质财富,使农村经济发生了一系列深刻变化。在一些发达和比较发达地区,乡镇企业已成为农村经济的重要支柱和国民经济的重要组成部分。但是,伴随着乡镇企业的迅速发展,乡镇工业对环境的污染和对生态的破坏影响日益突出。这一开头就将研究的问题与命题的发展趋势,当今乡镇工业对环境的污染和对生态的破坏影响紧扣一起,使人们认识到治理环境污染的紧迫性。3、指出危害法许多争鸣、纠错的小论文,常常指出某些弊端,让人们骤然心惊,晓知解决问题的紧迫性。4、概述论点法在前言部分,作者将主要观点集中呈现给读者,给人一种整体感,这无异于交给读者一串钥匙,往下阅读便是尝试去打开一扇扇大门。5、设置疑问法设置疑问主要是给读者留下悬念,让其在好奇心的驱使下迫不及待地关注研讨的问题。以上是写好科技小论文开头的五种方法,值得说明的是开头的方法不胜枚举,且各种方法常常是有机结合,渗透并用。四、分述要点经验材料繁多复杂,怎样使它们井井有条地统一于中心论点呢?在小论文的主体部分,采用分条论述的方法,往往得心应手。这种写法的好处是条理性强,层次清楚,给人全面深刻的立体感。当然,每个观点,都必须是深思熟虑的结晶,概述性要强,客观性要强,创新性也要强。五、用好材料科技小论文不是简单地将手头材料罗列成文,深透的说理,规律的导引是其本质特征。观点和材料是相辅相成的,论文的价值体现在论题的价值,论题的价值又通过材料的论证体现,二者的有机融合,就会形成一篇很好的科技小论文。六、文稿写作常识为了减少编辑发稿时的困难,也为了减少论文排版时的差错,作者在撰写科技小论文时,还要注意掌握一些文稿写作常识。一般来说,要注意以下问题:文稿用标准稿纸书写清楚(或者用电脑打印)。每格一字,标点单独占一格。不需排印的说明文字一律用铅笔标注。书写时应使用规范的简化字,防止错别字,更不要杜撰生字。除成语、古文和引用文献的数字外,一般数字用阿拉伯数字。公元的世纪、年、月、日、时、分、秒均用阿拉伯数字。年份不能简写(如1999年不能简写成99年)。五位以上的数字可用”亿“、”万“作单位。四位以上的数字连写,不用分节点;外文字母、化学符号等要写得端正清楚。外文应用印刷体书写,大小写必须分明,并用铅笔标明玩儿文种,正斜体和上下角标。此项内容请以中学教材中的写法为准,化学结构式中各个线条位置的排列必须准确;数学公式和化学方程式应另行居中书写,并使用规范字体;使用规范的标点和其它的符号。书写时,破折号占两格、省略号占两格、连接号占半格,其余符号占一格。并注意顿号、逗号、冒号、分号、引号的书写位置;文稿中涉及到的计量单位应使用法定计量单位,文字叙述中用法定汉语名称;文稿中的表格应由作者填写清楚。表号和表名一般在表前,说明在表后。同一表格另页再写时,前面应注明”续表“字样。表内文字末尾不加标点符号,回行顶格;文字能叙述清楚的内容,一般不用插图。使用插图必须起到图文并茂的作用。要注意文字与插图的衔接搭配,插图均应按序编号。
