科技利弊的作文篇1

in this era of accelerating pace of life, the development of science and technology has become the focus of people's attention.

some people think that the development of science and technology is beneficial to mankind, but some people think that the development of science and technology has brought about disadvantages to mankind.

in my opinion, the development of science and technology has both advantages and disadvantages, but the disadvantages are still greater.

take the invention of the automobile for example. when the early automobile served for human beings, it did bring convenience to people, making people travel conveniently and quickly.

but now, there are so many cars, you can see them everywhere. an increase in the number of cars means an increase in emissions. with so much waste gas entering the atmosphere, the earth is unable to dissipate heat quickly, causing global temperatures to rise, melting ice at both poles and losing life there.

then came the invention of the plastic bag. although it's light and easy to use, it has to be broken down. but extremely difficult. a small bag can take decades or even centuries.

besides, they still didn't deal with it well. the used plastic bags are thrown on the ground and in the rivers, making the land barren and the rivers muddy. some living things suffocate because of the plastic bags.

last but not least, the mobile phone is a double-edged sword. if used well, it will bring convenience to people. if not used well, it can have very serious consequences.

there are a lot of young people who are nearsighted because of excessive use of mobile phones. some addicted to the game, life becomes decadent; others play with their phones while charging, causing batteries to explode and causing serious injuries.

the disadvantages of technology are far more than these, but we should not forget the advantages it has brought us. i hope that in the future, scientists can minimize the harm of the development of science and technology and make our home more beautiful.

现代科学技术正以前所未有的速度改变着世界的面貌，影响着人们的生活。丰足的衣、食，舒适的住、行，千百年来一直是人类最基本的追求。现代科学技术的发展，使人们的愿望逐步变成现实，让人们的生活跳动科技的音符。

寿命变“长”了

1900年全世界人均寿命仅为45岁，而今天这一数字正提高到66岁。联合国人口署已经把老年人的年龄界限定在“85岁以上”。人类寿命的大幅度延长，得益于20世纪医学的迅猛发展和生活水平的显著提高。

婴儿出生不久就要被接种卡介苗，1921年起进行人体试种的这种疫苗，消除了结核病的阴影。青霉素、乙肝疫苗、心脏起搏器、避孕药、器官移植、人造器官、显微外科、心电检测、超声波诊断、核磁共振诊断、断层扫描成像（ct）……这些今天看来很平常的发明和技术都是20世纪的重大医学成就。我国科学家在上海试验的转基因牛、羊，使人类看到了“动物药厂”的曙光。试管婴儿，克隆羊的问世，使人类生命之火越燃越旺。

在人类获得基因组的全部序列后，人类遗传密码的破译将进入全新的信息提取阶段。重大疾病基因将被发现，一些危害生命的疾病将会有希望治愈。

世界变“小”了

21世纪，信息技术将会从微电子向高集成度、低功耗、低成本方向发展，计算机向超高速、小型化、并行处理、智能化方向发展，通信技术向光纤化、数字化、综合化、网络化方向发展。信息技术的发展，将从根本上改变人类从事商务活动、交流、娱乐、学习，甚至工作的基本方式。

科技的发展使人类突破时空的约束，地球成了人类的村落。从公路到铁路，从水运到空运，运输工作的进步彻底变革了人们的出行方式。1903年，莱特兄弟用木头、电线、布料制作的飞机实现了首次飞行。飞行时间虽然只有短短12秒，却是一次划时代的事件。今天，日新月异的飞机制造技术，已可以使人们在24小时之内飞到地球的任何一个角落。

在过去一百多年里，无线电、网络技术等的发展，使信息插上了光速的翅膀。从电话到电报，从收音机到电视机，从移动通信到传真机，犹如中国古代传说中的“千里眼”和“顺风耳”，使人类之间的交流与沟通更为方便。你坐在家里的电脑前轻点鼠标，远在万里之遥的友人，便可以在瞬间收到你发去的电子贺卡。在昔日屯兵养马的陕西商洛山区，如今农民已经通过互联网把生意做到了全世界。

人类在突破空间约束的同时，也开始突破时间的约束。录音机、摄像机、录像机、激光唱机和数字音像设备的发明，使得我们可以把自己的音容笑貌留给后代，我们也可以耳闻目睹先辈们的风采。

劳动变“轻”了

科技解放了全人类，迅猛发展的科学技术将越来越多的人从繁重的体力劳动中解放出来。

电子计算机是20世纪最伟大的发明之一。从人脑的计算到电脑的计算，人类创造了“人脑创造电脑，电脑促进人脑”的奇迹。在第一台电脑投入运行后的10年间，它的运算量估计比有史以来人为大脑所有运算量的总和还要多。现在，计算机汉字输入问题已经得到根本解决，无数中国人可以使用汉字在计算机和互联网上自由驰骋。

科技对社会和经济发展的巨大贡献日益证明，科学技术是第一生产力。据估计，以科技为核心的知识对经济增长的贡献率20世纪初为5%～20%，而目前这一比例在一些发达国家已上升到80%左右。

do science and technology change our lives for the better or for the worse

nowadays,with the development of science,our life has a geat historic change than before. simultaneously,the changes were so rapidly that taking so many problems. the argument about the development of science and technology hence became ineluctable.

some people held the view that the development of science and technology was good. they believed that the advantage outweighed the disadvantage. owing to the development of science and technology,our life could get great abundant and convenient. the invention of electric light,new transportation,internet --nobody did not benefit from the development of science and technology. comparing with the past time,the health of human and the standard of our life had changed a lot...... nothing what having great improve did not depend on the development of science and technology. we would lose everything we had got if we lost it. however,the other people insisted that the disadvantage outweighed the advantage. the matters that science and technology took were unprecedented in spite of benefiting from the development of science and technology. the first problem was the pollution. it was the most immediate problem that the science and technology took. not only our water,but also our food became more and more insecure due to the pollution. moreover,we must care about our world to ensure it did not ruin by the war that new technology supported. the destruction of science and technology was lethal and unimaginable. nevertheless,there was another thing we have to face:the mrsa. nowadays,the modern means of science and technology couldn't deal with this problem caused by itself. so they had to say that the development of science and technology enhanced the fatalness of our life.

anyway,every coin has its two sides. so,we should be more dialectical when we do with the problem. only in this way could we let the science and technology serve for human better and better.

科技利弊的作文篇4

in the journey of life, we have gone through a long time, also experienced wind and rain, joys and sorrows, but through the years, what do we absorb? what did you learn?

when i was a kid, technology wasn't that advanced, and our homes were mostly just physical toys, not smartphones and tablets. with the change of the times, the progress of science and technology, modern civilization has gradually intruded into our life imperceptibly, replaced by the toys that we played happily when we were children. although the entry of civilization brings us a convenient life, it has buried the traditional things.

electronic products are always novel, progressive, enjoyable and technological in people's eyes, but what phenomenon does it make us produce? when you walk on the road, people seem to have cell phones on their hands, waiting for traffic lights, waiting for the bus... even when he was crossing the street, he risked his life and walked with his head down. the people he saw were so cold that they could not predict what would happen in the next second. civilization enables us to have a convenient life. when we buy things, we can shop online and buy the things we need without going out. it seems that people are praising the progress of the times. but while these advances bring us convenience, they widen the distance between people.

how can we improve this phenomenon? i think we can go back in time, and maybe modern children will find our childhood toys so interesting, or maybe it's the novelty of electronic gadgets that has caught the modern child's attention, obscuring the physical toys.

when i think of the things of my childhood, i have experienced the changes of the times, and the tradition has lost its original appearance.

科技利弊的作文篇5

科技，一把“双刃剑” 田紫嫣 科技， 让无数人为它趋之若鹜。无数的人，都渴望走进那神圣的科技殿堂。 正是凭着科技，人们创造出了一个个不朽的奇迹，譬如汽车；正是凭着科技，人们得出了一个个真实的结论，譬如地心引力然而，科技也

是一把双刃剑，提高了我们的生活质量，但也给我们的生存环境带来了隐患，你知道吗？ 现在，家家户户几乎都开着汽车，我们家也新买了一辆。汽车豪华而宽敞，就像是一座“移动的房屋”。在里面可以听音乐、看视频，只要保证流通的空气，甚至可以睡觉。坐在汽车上，开启车窗，清新的风儿扑面而来，那滋味别提多爽了；仰望着蓝天白云，背靠着软软的沙发，令人心旷神怡。而且，汽车的速度非常快，是旅游的上上之选。可是，凡事有利必有弊，汽车也不可幸免。其一：汽车比较耗油，偏偏汽油很贵，一升就得七、八元，还时不时涨价，简直就是只吃不吐的大黑洞；况且，为了汽车的美观，汽车上掉点鸟屎、被刮了点漆、车座太脏什么的，都要去洗洗换换，又得花掉很多钱；再有，汽车每年交的保险也不便宜。唉，自从有了汽车，俺老妈的钱包总是瘪瘪的啦！其二：汽车的尾烟非常污染空气，那鸣笛声也很刺耳，若是人长期生存在这种环境里，极其危害身体健康。唉，我多么希望汽车喷出来的是清澈的水汽，汽笛声可以变成优美动听的音乐啊！ 与高科技产品汽车相比，自行车“返璞归真”就有很多好处了。多骑自行车可以强身健体，而且没有尾烟，它的铃声也很清脆悦耳。可是，自行车也有弊端呀！ 真是“金无足赤，车无完车”。自行车的速度不快，去哪儿旅游还不得累死？雨天要穿雨衣，否则就得淋成落汤鸡；没有空调，夏天热得汗流浃背也没办法。 瞧，科技在发展，任何事物都有利有弊吧！ 现在，很多东西都是用木头做的：小到木筷子，大到木家具，还有造纸、建房可与此同时，森林也在快速地消亡。“十年树木”啊，人们栽种的意识还没有普及，植树的速度也远远跟不上。试想一下，森林资源在不断减少，它们可是地球的“绿化工程师”啊！工厂中源源不断地生产着各类高科技产品，可是，黑烟却从烟囱里冒出来，污染着空气。那些肆意排放的污水也让小河不再清澈，鱼儿们就算没被毒死，体内也满是毒素。唉，如果继续这样下去，地球上的新鲜空气还能存在多久呢？ 时代在进步，科技在发展。可我，一个五年级的小学生，却要高呼：科技，一把双刃剑！用得不好，会害人害己。
