纵观全世界,科技发展给人类带来的利益,无疑是不可否认的。
先从我们的饮食方面来说吧。饥荒一直以来都是中国古代人民最大的灾难之一,由于饥饿而死的人更是不计其数,直至第二次世界大战,全世界依然有大部分人在饱受饥饿所带来的煎熬。可是现在却大不相同了,随着科技的发展,全世界的农业水平都蒸蒸日上,各种异种嫁接和基因技术都在被开发,虽然这还是没能避免少数人因饥饿而死亡的悲剧,但是,科技发展还在继续,相信这个问题,以后一定会得到全方面解决。
再从出行的角度来看。古代我们使用的马车,牛车和小木舟,根本无法让一个国家真正有效率地运作起来。很多身处异乡的人都必须大费周章地准备一番,才能返回故乡,有的人甚至一生都无法再次回到家乡。直到十八九世纪,火车、汽车、地铁、飞机等一系列交通工具陆续被发明了出来,人类的出行才慢慢变得方便。以前,从一个省到另一个省少说也得好几天,现在只需几个小时,甚至更短,科技给人类带来的作用真是不可估量。
最后我们从人与人之间的'沟通交流来讲。在古代,身在他乡的人想与家乡的亲朋好友对话,只有通过让信使去送信才行,这样的方式,需要耗费大量的时间,而且风险极大,万一送信使在路上因为各种原因将信遗失,那么寄信人的期待就此落空了。而现在,电话、短信、电子邮件、qq、微信等即时通讯方式的发明无疑是通讯业的一种重大革命。想对别人说什么,只需几秒钟的功夫,别人就能知道。科技使我们的生活更加即时而有效。
虽然科技给我们带来了巨大的好处,但是由此造成的负面影响也是绝不能忽视的。科技带来的弊端有很多,比如汽车排放尾气,造成空气污染;工厂排放污水,使河流受到污染;温室气体排放,导致气候变暖;冰川融化,让人担心海水倒灌……
任何问题总能找到解决的方法,科技发展所带来的弊端也不例外。在我看来,解决方法有很多,比如把汽车改造成太阳能或电能驱动,用法律规范污水处理,多植树造林,进行五水共治……坚持做好这些,科技带给我们的麻烦就能一点点减少。
总的来讲,科技带来的利还是要大于弊的,只要我们好好运用科技,总有一天科技会更好地服务于人类。
当今的科技越来越发达,各种新奇的事物也越来越多,像是智能手机,电视,电脑等都走进了千家万户,成为了人们不可或缺的物品之一。而另一些东西,比如各种搜题软件,写作业机器人等,人们也许对于它们过于批判,但任何事物都具有两面性。而我认为,这些东西既有利又有弊。
举个例子,在我上小学的时候,有一段时间十分爱用搜题软件去搜答案,那一段时间我的作业天天都是全对,而且字迹工整,过程完整,一看就十分的完美。我因此也受到了老师的表扬和妈妈的夸奖。我越发的膨胀了,脸上尽是得意的神色,心中暗暗的想:哼,看你们谁还比的过我。我以后就是班里的“老大”了!正当我欣然得意时,期中考试骤然而至,把我一下子就给击垮了,在考场上,我看着那一道道似曾相识的题目,心中浮想联翩:这道题我曾经见过,我也知道它的答案是什么,可是我却忘记了它是怎么做的了!我的心中激起了惊涛骇浪,彷徨和无助一下子挤满了我的内心。我一直惴惴不安,心里像进了一只老鼠一样做完了这套试卷。结果可想而知,我考得十分不好。我就是从这个事情之后才自己去认真完成老师布置的作业的。作业其实就是让学生加强对于知识的记忆的`东西。如果你不去认真完成作业,那么你怎么能够加强课堂上所学过的东西在你脑子里的记忆呢?
说完了坏处,现在来说说好处。对于有些同学来说,有些题是真的十分困难,那么他们就可以用搜题软件。用完了搜题软件之后,要记得吃透并理解每一步过程中的思路,把它真正变成自己的东西。这样你下一次遇到了同种类型的题目之后就可以运用自如了。这对于自己也是一种提升啊!
现在的高科技越来越发达,可以干许许多多的事,我们在干任何事情的时候,都不能好坏不分的一味接受,而是取其精华,去其糟粕,学习他的优点,把优势最大化。但是不要让它占据你所有的时间。正确并合理的使用它,能使我们的青春更加丰富多彩。
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。
in recent years, studying abroad has flourished. thousands of schloars and students have gone to foreign countries to study. many people are sparing no effort in applying for going abroad.
attending schools abroad has many advantages. in the first place, students who have studied abroad can act as mediators between peoples of different cultures so as to promote international understanding. secondly, we can learn much more advanced knowledge of science and technology from the foreign countries. thirdly, we can enjoy the contact with new and different cultures so as to increase the awareness of our own culture. fourthly, we can learn a foreign language more quickly.
however, studying abroad may have disadvantages such as language barrier in the first few months or financial difficulties before getting a scholarship. in spite of these, the advantages greatly outweigh the disadvantages. it is advisable to attend schools abroad.

essay title:
the use of technology in education has increased in recent years. discuss the advantages and disadvantages of using technology in education, with regard to both teachers and students. give examples from your own experience of studying to support your argument.
technology in classroom is not new. indeed, technology has been around in education for decades-one and might be argued for centuries, if we classify the blackboard as a form of technology. "tape recorders, language laboratories tape recorders, language laboratories and video have been in use since the 1960s and 1970s, and are still used in classrooms around the world. computer-based materials for language teaching, often referred to as call (computer assisted language learning), appeared in the early 1980. ”(dudeney, 2007, p8)
technology is a tool in the classroom which tries to constantly improve the quality of teaching and the efficiency to allow people to become easier and more convenient in learning through science and technology tools. technology products have been gradually integrated into our life, and even have become an integral part of our lives. there are many technology products used in education. it has become a hotly-debated issue, whether the educator should greatly accept the development of technology. advocates of using technology in education argue that the science and technology can effectively improve studying, such as network education system, computer and multimedia tools. they are the leading cause of improving education diversity. however, other people believe that school should follow the traditional education. there are many uncertainties in technology products. students may be faced with many temptations and adverse influences from technology products. technology in the classroom needs to spend a lot of money. they claimed that it is wasteful, unwise and unacceptable. this essay intends to explain the pros and cons with use the technology in education.
first of all, the computer is the most representative of technology products usedin education. it can offer a range of services and convenience for students to study, suchas e-learning, reading online and researchinginformation. with the help of these resources, the students' learning will be improved greatly. clark (2008, p 37) claimsthat “reading online content is similar to reading printed material, but online material is designed
very differently from a book.” student will no longer worry about takinga number of books to school. aside from convenience, distance education programs can be economical and environmentally friendly. it is not necessary to connect with the internet; it will beeasy to find a book which read. maybe in the near futuree-books will replace paper books.
furthermore, tele-education has been increasinglypopular on the internet. wireless fidelity is now widely available on trains and in hotels, cafes, libraries and a variety of other public spaces. (clark .2008) students can use lap-top, ipad or mobile phone to study anywhere by connecting tothe internet. technology provides the possibility of learning whileon a bus or outside. it is not necessary to own the technology produce; the cybercafés has already offered the service. it is only necessary to pay a little money then to use theircomputers. even if far away from home or college, the students also can carry on with their studies. (clark, 2008) technology products are available to the learning spaces. in the students' learning sites are not limited at school or at home. the way and place of studyingis also becoming flexible.
on the other hand, technology products also bring some threat to students ’study. although technology products can bring convenience to study, it may also influence them in undesirable ways. people like to use e-learning because they can save every-thing. there is no need to read the material or make any particular effort tounderstand the content. it may lead to impairing the ability of students to analyst information and it may beeasy to make mistakes in their studying. (clark,2008) students will growdependent on learning tools to study and it may reduce their autonomous learning. over relying on electronic products may take a heavy toll on student’s study.
moreover, contacting with electronic products and network for a long time may easily suffer from a series of threat, such as, internet addiction, internet pornography and cyber-violence. admittedly, exposure to violent movies may lead to aggressive and antisocial behaviors. an avid pursuit of science and technology products probably may lead to internet crime. many parents said that children’s’ prolonged time working on the computer easily lead to testiness, decadence and selfishness. a growing volume of experience suggests that under the impact of negative net-culture, youths willpower is
weakened, which results in the increase of juvenile delinquency, personality defects, and damages to their physical, emotional and mental well-being.
technology not only plays an important role in students’ study but also influences the teachers’ job. students studying in school may find that technological devicesare increasinggradually. undoubtedly, the technology devices have become an indispensable part of educational tool in the classroom.
firstly, technology products probably offer a lot of information for teachers to prepare for their teaching.dudendy claimed that (2007, p8) technology is offered with published materials such as radio, photo or resource books for teachers. for example, in the internet an educator could find numerous materials and create a power-point courseware. class education will not be trapped in text reading, because technology can provide the condition which would makes the course moreeiching, interesting and easier to grab the attention of the students. according to experience, technology products have a great probability ofimproving the quality of teaching and promoting education.
furthermore, technology may help teachers to increase their efficiency and reduce workload in the school education. davies stated that (2010, p8) “if designed appropriately, computer-assisted assessment offers a number of benefits that can enhance learning and reduce the workload of administrators.” for example, assessments online, it can access a greater range of locations for paper examinations. teachers could transport students’ work from home and access grades from multiple locations. teachers may also teach in a tele-teaching format, whichallowsthem to potentially take on more students and course sections because meeting times are more flexible or non-existent. experience suggested that online assessment is feasible. students could submit their assessment to the campus network system, and then the teacher could check the homework and return marks, all online.
while technology use in education could bring a range of benefits, however, it also has some limitations. technology is essential for teachers but there are some instances
正方:关于科技发展是利大还是弊大这个辨题,我方辨友一致认为科技发展利大于弊.人类的生存方式,20万年前与10万年前相比,不会有太大的改变;3000年前与20xx年前相比,不会有太大的改变;600年前与500年前相比,不会有太大的改变。但是,今人与古人其实早已今非昔比,即使是现在与100年前相比,也已完全不一样。是什么推动了人类历史的发展?是什么让人类开始了新的生存方式? 我说,这便是科技,是科技的发展才推动了人类的进程,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?回首过去,看四大发明,独具鳌头;观天文历法,为之惊叹;览赵州拱桥,设计精妙;窥《本草纲目》,东方巨典;瞻圆周率值,七位小数;眺丝绸之路,发展经济;端青花瓷器,扬名海外。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,我们哪能住进高楼大厦?
反方:人类跨入21世纪,世界发生了多少惊人的变化。在人们为科学技术突飞猛进的发展欣喜之余,又经历了更好的不安甚至灾难。除了对高科技特别是生物科技的发展所带来的恐慌之外,战争和疾病似乎直接将人类带到了地狱之门。各种病毒的侵入,汽车身后的尾气,工厂的废气等等无补侵害着我们美丽的家园.试问为什么我们的家园受到了威胁,为什么树木被大量的砍伐,为什么空气不在新鲜,这一切一切正是科技带来的种种罪证.现代科技是给我们带了一些舒适与方便,可同时也带了幅面影响,试问没有了美好的环境人类该怎么舒适生存呢如果人们还不赶快对自己犯下的错误进行补救的话,人类终将会被科技所毁灭.
正方:在古代,人们迷信鬼神,认为人的一生是天定的,生老病死是天来掌控的;在现代,人们通过科技的发展,证明了迷信思想是不可取的,要通过自己的双手创造自己的生活。在古代,许多人得了重病,大夫也无能为力,只能眼睁睁地看着病人痛苦地死去.可现在,通过科技的发展,大部分疑难杂症已能成功治愈,人们不用为生病而烦恼。以上所举的例子,只是科技发展为人类造福事例的冰山一角。科技发展得如此迅速是古代人想都不敢想的。为什么电视上、报纸上,几乎天天说要提倡科技发展,因为千年的飞天梦是怎样圆的是科技的发达;通迅的便捷是什么造成的是科技的发达;身患重病的人为什厶能重新过上幸福的生活?是科技的发达!如果说科技的发展是错误的,那么,伽利略、牛顿、爱迪生、居里夫人、爱因斯坦等发明家、科学家,为什么要将自己宝贵的一生献给科学?为什么要将那么多宝贵的时间用在“错误”的事业身上?难道他们是没有判断能力的吗?有谁认为他们的死毫无价值,又有谁认为他们为科学献身,根本没有意义?
反方:科技发展是给我们的生活带来了好处,这点我们并没有否认.但是我方认为科技带来的弊处大于利的.首先汽车虽方便了我们的出行,但牌坊的尾气造成环境的污染,影响人类健康.其次,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,是人情淡薄.还有就是网络的出现,是一些不法分子有了可乘之机,扰乱人们的生活等等着一系列你们所谓的高科技所带来的副作用,是不可否认,试问我们怎么能坐视不理呢?
正方:科技的发展当然也造成了一定的负面影响,但本来这些影响应是很小的,可人类却如一个放大镜,把这些负面影响放大。如果人类能自觉的把塑料袋重新利用,而不是随意乱扔,会造成这么严重的白色污染吗?如果人类能有竭制的开采资源,会造成现在的资源短缺吗?如果人类能节约用水,工厂不违规排放污水,会造成现在严重缺水的状况吗?还有许多诸如此类的事情正在上演,而有些人不但不自省,反而一味的把责任指向“科技”。我为这些人感到可笑,感到无可救药。
反方:刚才对方辩友所提的只不过是假设罢了.请回到现实中,试问如果没有科技的阻挠又和需现在费这么大力气去宣传保护环境呢?再说现在的网络问题正是大家所苦恼的,网络是许多本该是祖国幸
福的花朵的`少年误入歧途,走上犯罪的道路.你说网络虽然可以方便我们查找资料,可是这么一个小优点又怎能和祖国的未来相比呢?
正方:可是科技的发展还有更多的好处,火箭的升空,圆了中国人民的百年飞天梦,鸟巢水立方的建成,圆了中国的奥运梦想,试问没有科技中国人怎么能圆梦呢?有何必抓住网络这个问题不放呢?
反方:对方辩友,网络问题事关重大,青少年是祖国的花朵,祖国的未来靠的就是青少年,网络把少年引入歧,网络害得多少少年无法自拔,倘若祖国的下一代都沉迷与网络,那么我们的祖国还有更多的梦想又怎么实现呢?请问对方辩友.
正方:我们是幸福的,我们是幸运的,我们赶上了一个科技高速发展的时代,一个充满高科技的时代,这不光光是我们的祖先在进化时选择了发展,选择了进步,也包括了所有人的不懈努力,刻苦钻研,我们今天的日子时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,认知自己;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周围的一切,不都是他们给我们换来的吗?生活如此舒适,生活如此惬意,生活如此美妙,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,这不都是科发展给我们带来的好处吗?
反方:在原始时代,人类只需地表面的资源就能生活,只需要溪水,树上的果子,草籽等生活资源也能其乐浓浓啊.后来出现了工具 ,然后养殖,资源利用到破土一尺,再后来煤矿,金属等资源深入到底下100米,再后来深入5000米,人类加速的向地球深层索取资源,当人类利用地核资源时,地球也就到了灭绝的时候了,对方辩友,这足以说明科技发展总有一天回毁灭地球的,到时候也是聪明反被聪明误啊!
正方辩友:只要我们有利的把持住,控制住科技,地球也不会毁灭的.
正方:科学技术是第一生产力,高新技术及其产业促进了了国民经济的发展,可以说高新技术及其产业已成为当代科技发展的火车头科学技术改变人们的思想观念,提高人们的生活水平,促进了社会主义文明的发展。 科学发展可以反映一个国家的经济发展水平和国民经济素养。科学技术是第一生产力,是先进生产力的集中体现和主要标志。我过要发展生产力,提高经济效益,首先要靠科学技术的发展。从构成生产力的要素来看,科学技术可以使劳动工具得到不断改善和更新,可以提高劳动者素质,可以使劳动对象得到充分利用。总之,科技发展可以极大地解放生产力,甚至产生新的产业部门和导致国民经济的突飞猛进。我们要坚持科教兴国战略,才能使经济增长方式摆脱粗放型的老路,转移到以提高经济效益为中心的轨道上来,切实注重经济发展的质量和效益电视在生活中是不可缺少的。我们可以看新闻,了解国内外的事;可以看动画片,放松一下;还可以不去现场看节目、表演;比如说,这次奥运会吉祥物揭晓,就可以在家看转播等等一系列的科技着实给我们带来好处,所以我方坚持认为科技发展利大与弊!
反方: 当今社会,科学发展迅速,许多高科技产品不断涌现,电脑、汽车、洗碗机、洗衣机已经走入寻常人家的生活。它们确实给我们的生活带来了不少便利,但是与此同时,它们也使人类的基本能力逐渐丧失。有了电脑,人们不再用人脑去思考一些东西,因为只要利用电脑就能办到;有了汽车,人们不再习惯走路散步,取而代之的是开车兜风;有了洗碗机,人们不再用手去洗碗,也许有一天人类会忘记怎样洗碗。科技的发展,让人欢喜让人忧。喜的是它给我们的生活提供了最大的便利,忧的是它终有一天会让电脑代替人脑,机器代替双手,到时主宰这个世界的不再是我们自以为聪明的人类,而是那些人类发明的机器!所以,我认为:科技的发展会抑制人的全面发展! 再如飞机、火箭、网络、卫星最初都是为军事的战争而出现的相同的科技在为人类造福的同时也被用作毁灭人类的帮凶。所以我方认为:科技发展弊大于利!
