科技的利弊作文800字（第1篇）

　　In this era of accelerated pace of life, the development of science and technology has become the focus of peoples attention.

　　Some people hold the opinion that the development of science and technology is beneficial to human beings, while others hold the opinion that the development of science and technology has brought disadvantages to people.

　　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. In the early days when cars served for human beings, they really brought convenience to people and made it convenient and fast for people to travel.

　　But now, there are so many cars, you see them everywhere. More cars means more exhaust emissions. A lot of waste gas enters the atmosphere, and the earth cannot heat itself fast enough. This causes global temperatures to rise, and the ice in the north and south poles to melt, and creatures there to lose their homes.

　　Then came the invention of the plastic bag. Although it is very light and easy to use, it needs to be broken down. Its extremely difficult. A small bag can take decades or even centuries.

　　Besides, they still didnt handle it well. The used plastic bags are thrown on the ground and in the river, which impoverish the land and muddy the river. Some creatures suffocate because of the plastic bags.

　　Finally, there is the mobile phone, which is a double-edged sword. If used well, it will bring convenience to people. If not used properly, it can have very serious consequences.

　　There are many young people who are short-sighted due to excessive use of mobile phones. Some addicted to games, life has become decadent; Others play with their phones while charging, resulting in battery explosions and serious injuries.

　　The disadvantages of technology are far beyond these, but we should not forget the advantages it has brought us. I hope that in the future, scientists can reduce the harm of the development of science and technology to the minimum, so that our home more beautiful.

　　科技就像一把双刃剑，它在给我们带来福音的同时，也制造了一些麻烦，如：环境污染，基因工程可以用来治病，也可以毁灭人类。

　　当今时代，科学技术以成为推动生产力发展的巨大动力。

　　在战争时期，科学给予人们相互毒害和残杀的手段。

　　在和平时期，科技会使我们生活匆忙和不安定。

　　忘掉过去，展望现在，电脑几乎家家必备，电脑的用途广之则广，如：聊QQ玩、玩游戏、找资料等等。但是有的人由于沉迷与网络而不能自拔，有的人因为在网络中玩太多战争之类的游戏而不能自拔，有的人因为在网络中玩太多战争之类的游戏而去杀人，还有的人因为家里没有电脑而去网吧，但是手中没有钱，父母又不给，就去抢劫，杀人要钱去网吧，从而走向犯罪的道路，这就是网络的弊处。

　　网络的利处也很多，比如：在21世纪有的人用电脑创造了游戏，还有利用浏览器来查阅征文，手抄报和一些重点知识从而取的好成绩。如果在电视上没有看到的电视节目就可以从电脑中看到。

　　科技是把双刃剑，既有利又有弊。只要我们把握一个渡就可以保证利比弊大。

　　在进行利用网络的时候，千万不要忘记这一点。

　　In the journey of life, we have gone through a long time, also experienced the wind and rain, joy and sorrow, but through the time, what do we absorb? What did you learn?

　　When I was young, technology was not that advanced. At most, our home was just some physical toys, not to mention smart phones and tablets. With the change of The Times, the progress of science and technology, the modern civilization unknowingly gradually into our lives, instead of our hours to play with the toys. Although the entry of civilization brings us convenient life, it has buried the traditional things.

　　Electronic products are always novel, progressive, enjoyable and technological in peoples eyes, but what phenomenon does it make us produce? When you walk on the street, people seem to have mobile phones in their hands, waiting for traffic lights, waiting for buses... ", even when he was crossing the street, he risked his life to walk with his head down, and the people he saw gave him a cold sweat, all of whom could not predict what would happen next. Civilization, so that we have a convenient life, shopping online, and home match, do not go out can buy the necessary supplies, it seems that people are singing the praises of the progress of The Times. But while these advances have brought us convenience, they have lengthened the distance between us.

　　How can we improve this phenomenon? I think we can go back to the past. Perhaps modern children will find the toys we played with as children so interesting. Perhaps it is the novelty of electronic products that attracts the focus of modern children and obscures the physical toys.

　　Thinking of childhood toys, I have experienced the change of The Times, so that the tradition has lost its original look.

So, after a summer vacation, I put on my first pair of glasses, complaining. After that, she stepped out of the mobile phone world under the education of her mothers.

　　With the rapid development of science and technology, some disadvantages brought by search can be controlled, and some can not be controlled, so we should try to control what can be controlled.

　　我在生活中，觉得科技的发展对我们是利大。同时，科技的发展也使环境的的污染在随着上升，也会给人类带来许许多多的弊端。

　　比如说在我们生活中，有了科技的进步是不错，但是在科技进步的同时，又增加了环境的污染，有时还不只是一点儿污染，甚至是很大的污染。生活中有许许多多的例子，就拿几个简简单单的例子来说吧！先拿明显的来说，那就是汽车！虽然汽车是一个很方便的交通工具。但是，由于汽车的数量大大的往上升，那么排出来的大量尾气就会污染到我们的空气，我国的天空已经大部分被空气污染包围着。很少看见蓝蓝的天空，悠悠的白云，夜晚的星星。现在，天空中的星星很少，没有几年前那么多的了。以前的那些星星，满天都是，数都数不过来。但是，现在呢？几乎都没有了，只是偶尔的看见两三颗闪着微弱光芒的小星星，好像自己的寿命马上就快over了一样，让人看了就影响情绪。现在与以前比，不都是科技发展害的吗？如果没有汽车，如果没有烟囱，如果没有垃圾，我们怎么不会每天都能看到蓝蓝的天空，悠悠的白云，夜晚星空上眨着眼睛的星星呢？所以，我认为科技发展是弊大，虽然也有很多认为是利大，但是，如果我们的科技发展到很高的时候，恐怕地球就该灭亡了。所以，我想让现在的人去研究关于怎样才能把汽车改成太阳能汽车的话，那我就不会感觉到科学技术的发展是弊大。希望能让那些科技人员改正过来。

　　科技的发展给我们带来了坏处，也带来了好处，不过要把那些坏处改正过来。

科技的利弊作文800字（第6篇）

　　In the 21st century, many people have Apple, Samsung, tablet and other electronic products in their homes. Some people even have several mobile phones. All of these things are brought by science and technology.

　　However, have you ever thought that while science and technology products bring us convenience, they will also bring us many disadvantages. In the past, when our parents were young, it was good to have a TV at home, so at that time, parents rarely will be myopic. Nowadays, many of our classmates have cell phones, computers and tablets at home, leading to thick glass in our eyes due to electronic products before we enter middle school.

　　In addition, when you go to bed at night, mobile phones, tablets and other things are placed in the room to charge. When you fall asleep, these things are also quietly radiating to you. This will cause you to be less energetic the next day, and you will not be able to concentrate in class, and it is easy to be distracted.

　　And then theres transportation. With the improvement of living standard, every family has their own private cars, which can not only sleep more but also dont have to wait for the bus. However, more and more cars in cities emit more and more carbon dioxide. It is only the ozone layer, the god of protection of the earth, that is severely damaged. Even our island city of Zhoushan will also be affected by the haze.

　　We should work together to maximize the benefits that technology brings to us, and at the same time reduce the disadvantages that technology products bring to us, so that we can enjoy a high-quality life.

　　科技发展是利大还是弊大？很多人都无法给出真确答案。

　　如果世界还是以前的，人们出行会有很大的不便。人们可能还活在那种茹毛饮血的原始生活，并且有些疾病无法医治，只能眼睁睁的看着那些人们去世。人们会越来越愚昧无知。现在科技发达了，人们告别了那茹毛饮血的生活，许多病可以医治，人们的健康就有了保障。生活也更丰富多彩了：电视可以让人们知道许多事，电话又可以让相聚很远的两位朋友得到联系。网络的出现，使许多人在家就可以看到很多的新闻，可以看书，还可以学习。在电脑上还有淘宝、天猫等网购中心，让人们不出门就可以购买很多好东西。现在许多学校都建立了信息室，可供在校的学生、老师查阅很多资料，帮助学生们的学习更上一层楼。可见利大于弊。

　　可有些人为了钱财滥捕、滥杀小动物。化工厂排出的废水、废气、废渣等又严重的污染了水资源、森林资源、大气资源，破坏了自然环境。汽车的出现，虽然方便了我们的出行,但牌坊的尾气造成环境的污染却影响我们的健康；电视等娱乐设施的出现,虽然给人们带来了方便,但是却无形的阻隔了人与人之间的交流；更是网络的出现,使一些不法分子有了可乘之机,扰乱人们的生活，还使一些正在美好学业上的青年坠入网络陷阱。以前人们捕捉食物，躲避野兽，渐渐得养成了强健的体魄。现在呢，小孩子们天天过着衣来伸手、饭来张口、无忧无虑的生活，小孩子渐渐变的懒惰起来，身体也变的虚弱。可见弊大于利。

　　科技发展有利也有弊，只要我们爱护环境，不沉迷于网络，就一定可以利大于弊！

　　Science today, has become an indispensable part of our life, but science brings us convenience, but also brings us endless hidden dangers.

　　Science in the past ten years, it can be said is the rapid development of ah, but at the same time, the environment is changing with each passing day ah, in the development of science and technology, to bring convenience to human life, have thought of our survival of the earth is taking place in the earth-shaking changes? When we are driving private cars, driving on the double-lane road when have not thought, in the world, there are more and more lives are disappearing? Have you ever thought about what will happen to human beings when the primeval forest disappears?

　　Yes, science is a technology that can make it convenient for us, but the saint said, "No man is perfect, no gold is perfect." So if science has advantages, how can it not have disadvantages? There is no perfect person and no perfect thing. Take cars for example. Nowadays, cars have more and more comprehensive functions, but their exhaust emissions are also increasing, and the probability of car accidents is also increasing. Now, on average, tens of thousands of people lose their homes and lives due to car accidents every day. Finally led to the tragedy.

　　With the development of science greatly beyond the previous, such as cars, trains, planes and other means of transportation are also popular, now we are not only physically weak, but also easy to get sick. Although the medical technology is very advanced, but the road is higher than the devil, it is also because of the development of medical technology today, led to the accelerated mutation of bacteria. So much so that scientific medicine has been unable to keep up with the evolution of the virus, and perhaps the extinction of the human race was due to a pandemic.

　　In a word, with the development of science and technology, there are advantages and disadvantages, but the advantages and disadvantages are really to our own weigh. Dont do things that are harmful to others.

　　There will always be advantages and disadvantages of science. Just as the Book of Changes says, everything has two sides, both Yin and Yang. However, the number of Yin and Yang depends on whether the creator has taken it into consideration. So when we create another thing, we must take a long time to think about it and not let the disadvantages outweigh the advantages.

　　教室里发出了一阵不满的声音。“什么？不可能！”“你说的一点道理都没有！”……教室里一阵喧闹……

　　这声音惊动了屋顶的小鸟。什么情况？原来，是咱班在开辩论会呢！

　　“随着科学技术的发展，人们的生活发生了日新月异的变化，给人们带来了便利，但是一些新的弊端也随之产生。那么，是利大，还是弊大呢？请正反方开始陈述各方观点。”

　　一个矮矮的“四眼仔”站了起来：“我方认为利比弊大，因为人们的生活确实变好了。电话加快了通讯，汽车加快了生活的节奏，电饭煲、煤气炉可以做一些可口的饭菜。”

　　“啪！”一个高个子应声站起：“虽然科技是进步了，但也有一堆的弊端，例如：汽车的尾气，煤气里的氢，都会导致臭氧层的空洞日益扩大！”这个同学说得头头是道，显得胸有成竹的样子。

　　“嘿！你说得挺好！你不穿衣服、不用手机、电脑、电话和交通工具呀！”一位胖子大喊道：“你要是能，我就服你！”

　　我也不甘落后，一拍桌子，显出很威严的样子：“要这样的话，我能，那是因为——你们科技制造出的‘IT6超级细菌’！”

　　对方被说得哑口无言，我方胜出。

　　这就是咱班的辩论会，一场别开生面的辩论会！

　　Science and technology has changed the world, indeed, the emergence of computers, the Internet, is the earth like a spiders web linked together; The invention of the telephone made it possible for people to transmit messages for thousands of miles; With the advent of airplanes and cars, people can travel thousands of miles. However, when we are enjoying the achievements of science and technology, the brush strokes of technology products should not be underestimated.

　　Dont say far, say near. Youve seen cars, these are the guys that run amok on the road every day, because theyre fast, because theyre made of iron. Car accidents also often happen, tone good words, lack of arms and legs, if you straight and the car collided, did not go to the west is not the letter of the lucky. With the car exhaust carbon dioxide exceed the standard, a day suck ten, suck a two or three years will get lung disease.

　　Computer is also a double-edged sword, since his appearance, seconds killed countless peoples eyeballs. If you look at famous people before the 20th century, how many in a hundred wore glasses. But now, dont wear glasses always think other people are more learned than you. There are 47 students in our class alone, more than half of them are "four-eyed frog". If we give it a few years, the whole world will be opticians. Another disadvantage of computer is that there are a lot of online games, games can be a big virus. People often fall into the trap of online swindlers and get cheated out of a lot of money. There are many students addicted to the game, unable to extricate themselves, academic performance plummeted. In order to buy a card to recharge the game, unexpectedly to mom and dad place to steal money, the result grew up to become a thief.

　　Technology has two sides, one is good, the other is dull. Only the good side is polished off. Talent is where technology plays the biggest role.

科技的利弊作文800字（第11篇）

　　随着科学技术的发展，使我们的生活发展了很大的变化。不过，这些变化不都是朝着好的方向发展的，有时候，科技的发展也给人类带来了新的问题。比如说，汽车的发明，给人们的出行带来了方便，但是也带来了环境污染的问题。

　　因此，我个人的观点是科学发展弊比利更大些，因为随着科学发展的更一步变好，科学发展对地球的危害也就越来越大了，人们制造出了汽车，有钱的人都买起了汽车，开上了汽车，这样，汽车排放出来的废气球造成了对空气的污染，希望买车的人买小排量的汽车或少开汽车出行；比如说，科学发展让有钱的人当上了老板，办起了工厂，这样的`话，有些工厂只顾自己的利益，不顾别人的利益，把污水排到流水中，污染了水资源，希望那些工厂想一想别人的利益，也希望能查处那些工厂；再比如说，科学发展好了，发明出了塑料袋，只要到一个地方买东西就会白送你一只塑料袋，带了后来，家里的塑料带太多了，有的人就把塑料袋随便一扔，照成了白色污染，也有一次对空气造成了污染，因此从去年起，国务院为了不再造成白色污染，决定去那些大超市（比如国商超市和三江超市）买东西的话，如果要用塑料就得买，而不是白给你一只塑料袋，这样的做法是为了让我们学会用环保的袋子。

　　最后，我再次声明一下我的观点，那就是科学发展弊比利更大些。

科技的利弊作文800字（第12篇）

　　In the 21st century, with the rapid development of all kinds of goods and the continuous progress and innovation of science and technology, I think the advantages of the development of science and technology outweigh the disadvantages.

　　First, technology has revitalized our country. For a country, reform and innovation are indispensable, as is the development of science and technology. You see, Chinas science and technology is advancing by leaps and leaps, the thousand-year flying dream has come true, the Birds Nest water cube has been completed, the Olympic dream and the World Expo dream have come true, human beings boarded the romantic moon and looked at the blue earth... This one of the ancestors only dare to fantasy dream, now with science and technology will it round!

　　Secondly, technology has come into our lives and the Internet has covered the whole world, making the world a "big family". In this way, everything seems to be much faster, as long as the move of the mouse, you can convey information to the "18 thousand miles" away. On the Internet, even though people are thousands of miles apart, they can communicate and talk together and become bosom friends.

　　However, imagine what life would be like today if technology stopped developing, or even went back hundreds of years. A minor illness and you lie in bed waiting for death; If you want to drink water, you have to dig a well and carry water from it. Some news want to tell distant people to ride a thousand miles...... Without tall buildings, safe vegetables, transportation, communication tools, energy efficient light bulbs, and so on, no one will be lamenting the disadvantages of technology development when the world goes back to then.

　　Therefore, only from the above aspects, we can know that the advantages of the development of science and technology far outweigh the disadvantages, it is because of the development of science and technology, our life will be so beautiful!
