科技类作文

Directions: For this part, you are allowed 30 minutes to write a position on the topic Electronic Dictionaries. You should write at least 150 words, and base your position on the outline below:

1)电子词典有很多好处。

2)电子词典也有许多弊端。

3)你的看法。

Electronic Dictionaries

In recent years electronic dictionaries have bee very popular as a study aid among students.

Compared with a traditional dictionary, this kind of new dictionary has many advantages. First, in parison with a traditional dictionary, it is obviously very handy and convenient. Besides, due to its multifunction, it is also very helpful. It can not only translate words from English to Chinese, but vise versa. Some even can teach a learner how to pronounce a word. Most important of all, most of the entries in electronic dictionaries are paratively updated.

On the other hand, an electronic dictionary has its disadvantages. To begin with, the definitions in the entries are very limited. In addition, there are not enough explanations, patterns, or examples to illustrate the correct usage of a word. Last but least, constant use of this study aid make people too much attached to the dictionary and bee lazy, which will lead them to form a passive and lazy attitude towards learning.

As far as I am concerned, we should use it properly and should have a good English dictionary at hand and treat the electronic one as a makeshift(权宜之计), when necessary.

Internet and Our Life

Internet is now one of the best forms of media,with its swiftness and interactivity.Internet is being the foundation of our modem society.   With the assistance of Internet,more people can now municate with one another more freely and quickly.Internet also serves to be a great source of wisdom and creation.It is already being the electronic library of the future,giving vent to creativity and ingenuity unparalleled in human history.But Internet is a double-bladed sword.Its ability to distribute information and connect people around the world is often abused by us.Junk mail proliferates the Internet.Every year,many young people are deceived by their online friends The damage we have suffered from Internet is also too revere to recover.

Indeed,Internet access connects many of us to a world of information at the touch of a button.Internet is such an integral part of our life.In order to have Internet serve us human-beings well,we must not take its negative sides for granted.Web sites,especially the web sites available to the young children,must be strictly censored.It is time we took effective measures to minimize the side effects of Internet.

Cell Phones

Nowadays,with the rapid development of IT and information industry,cell phones play a dominant role in people’s life.But,like everything else,they have both favorable and unfavorable aspects.On the one hand,the mobile phone is portable and convenient.Being wireless,you can carry them ever

ywhere with great ease.You can reach a person wherever and however far away he is.On the other hand,it is a Mend indeed.

Whenever you e across trouble,you can call for help immediately.

However,just as every coin has two sides,the cell phone also has its many disadvantages.Some people plain that mobile phones give unpleasant noise on some important occasions when the owner forgets to turn them off.And it also cuts into people’s spare time,because with the mobile phone the boss can easily reach them and call them to duty during their spare time.Worst of all,the electromagnetic wave emitted from the phone is said to be harmful to people’s health and does often cause headaches to the owner.

In my opinion,with its expenses greatly reduced and China’s entry into WTO,the cell phone,will face an even brighter future in its development.They have changed the way we municate an.d have made our life more convenient,and thus will stay in people’s life.

作文三:《科技类作文》1800字

科技,时间,进步

光阴匆匆,千年历史如今想来也不过浮生一梦。不管那名士风流,还是什么将门虎将,在漫漫时光长流中也留不下深刻的痕迹。真正留在人们心底,受人重视的便是科技的进步。科技、时间、进步,向来相携出现,宛若三生兄弟,颠覆或者推动了一个王朝、国家的发展变化。让我们且看那时光年轮推动,去见证那历史变更的时间轴„„

战国。烽火连天,战事纵横,战国是一个乱世。而战国后期,处于蛮荒之地的秦国日益强大,威胁东方六国,为之后的秦始皇统一天下扎下了坚实的基础。这是缘自什么?都江堰心思独特,郑国渠惠泽关中万民;使成都成为天府之国,关中成为富庶之地。战国时的风流人物、名臣良将今已藉没无名,而蜀郡太守李冰、水利专家郑国却凭借造福民众的两大工程流芳百世,深受后人钦敬。

两汉。纸张取代了携带、书写不便的竹简,更替了价格昂贵、贵族专享的丝帛,以其独有的易书写、价便宜名扬四海,造福九夷,让世界人民的生活质量有了很大的提高,更多人可以识文断字,两汉朝堂上也涌现出更多的饱学名士,两汉因此得以享国400余年。而东汉为造纸术做出重要贡献的宦官蔡伦,生前封侯,富贵一生,死后也受万民敬仰,他从卑贱的宦官蜕变成高贵的侯爵,无疑是科技给了他机会。科技,将汉朝推上了中国上下五千年的第一个高峰。

南北朝。南朝博学多才的数学家祖冲之将圆周率精确到小数点后7位,比欧洲数学家早1100多年;祖冲之还计算出一年的日数约有365.24281481天,与现代科学所定只相差50秒。北魏农学家贾思勰撰写《齐民要术》,为后世研究农学打下基础;北魏地理学家郦道元撰写《水经注》,为治理洪水、了解地理提供了宝贵的资料。南北朝涌现出各种人才,为之后的隋唐盛世铺平了一条康庄大道。

唐朝。盛唐火药,震惊天下。从开始的炼丹所用,到最后的作为

军事利器,无不体现者火药的巨大作用。长安洛阳,气势恢宏。以其独特的皇家威仪和其巨大的后世参考价值享誉海内外,成为日本平安京、新罗金城、高句丽平壤和渤海国上京龙泉府的模仿对象。科技,将盛唐推上了中国上下五千年的又一个高峰。 宋朝。活字印刷术改良了传统的雕版刻印,让经典著作更加普及;指南针与方位盘首次结合,开启了北宋航海事业的新篇章;改进了唐时火药,发明出了大炮前身——"管状金属火枪";杨忠辅制作统天历 ,以365.2425日为一年的长度,跟现在世界通用的格里哥利历完全相同。宋朝,亦是中国科技的巅峰时期。

元朝。元代研制出了我国兵器史上第一个金属管形射击火器——火铳,元朝铁骑踏破欧洲,开创中国最广的地域史,火铳功不可没。具有伊斯兰风情的建筑跟中国古代建筑技术、风格融合,开创出建筑史上的新派别。

明朝。李时珍著《本草纲目》,完善的药草知识让中国古代医学进步巨大;郑和率航队到达西洋三十余国,开阔了国人的视野;光学仪器制造家孙云球制造放大镜、显微镜等几十种光学仪器,光学研究因此发扬。

科技能令一个国家进步,令一个民族兴旺,相对的,抛弃科技的结果就是血般残酷的现实。满清的闭关自守,愚蠢的“禁海令”,以及国人对目前进步的骄傲自大、不思进取,让中华民族经历了上下五千年来最惨痛的历史。长城挡不住洋人的枪炮,剑矛敌不过倭寇的机关枪,圆明园惨遭洗劫,中国人的颜面被无情的践踏。可笑、可叹、可恨的是,当时上至皇族,下至庶民,疯狂的迷恋一种“新科技”——鸦片,中国“东亚病夫”之名,跟中国四大发明一样,世界流传。那屈辱的一条条不公平条约,那流失的一件件珍宝,那哭泣的一个个

百姓,那一个个沉浸在纸醉金迷、红灯绿酒里的上层贵族„„香港,外兴安岭以南、黑龙江以北的大片中国领土,台湾,澎湖列岛,辽东半岛,澳门„„中国固有的领土割据给了列强。那是中国被钉在耻辱柱上最黑暗的历史,也是中华儿女最不愿回忆的历史。

时光的齿轮继续转动着,不为任何事做任何停留。现代中国科技发展迅速。两弹一星,奠定地位;杂交水稻,福泽世界;神舟五号,载人奇迹;嫦娥一号,实现梦想;发现猿人,考古突破;长江三峡,水利枢纽„„现在的中国,重新以世界大国、强国的姿态屹立在世界东方。中国人民是创造的,中国人民是不屈的,中国人民是崭新的。

时间伴随着科技,科技牵引着进步。社会在改变,时代在变迁,中国在复兴。要想让中国走上复兴之路,重新屹立于世界民族之林,科技,成为我们最重要的筹码。让我们从小打好基础,养成创新、勤学、好问的良好品质,让中国,在我们这代人手上绽放出更加璀璨的光芒!

作文四:《雅思写作素材之科技类》3000字

雅思写作素材之科技类

雅思写作科技类一直是雅思考试热点中的热点,在今年已经考了七场,差不多每月一次的频率。而且科技类常常与新兴媒体相结合,比如网络、电视等。为此小编特收集整理雅思写作科技类素材整理,分享给大家,希望对大家有所帮助,文中观点仅供参考。   2015年雅思写作素材免费下载

例如,今年雅思写作科技类考的题目也都是老题:

20130323 Scientific progress influences our daily life greatly. Do you think this is a positive or negative development?

201300718 Internet has great influence on shop, job, and

munication. Nowadays people don’t have to meet friends face to face but by internet. What are the advantages and disadvantages?

雅思写作科技类话题常常会从两个角度考察,一个是总体的科技发展或者科技进步,并不说具体是哪一种科技,比如上述的第一个考题。另一个就是具体到某一种科技进步,比如电脑、电视等等,像第二个例题就是这种。但是不管哪一种,其实都是换汤不换药的,相同或者相似的观点、素材、论据都是可以通用的。所以同学们一定要学会举一反三。

对于这类雅思写作科技类话题,想必每位雅思考生都会准备,而且这也是老师上课所必讲的话题之一。但是很多考生发现,越是考这样的常规考题,学生貌似是有话可说,可是这话说得不够好,总也得不到高分。所以如果考到了这样的“大众考题”,考生想到达到

“outstanding”还是需要一定的真功夫的。今天我们就一起来学习一些地道的英文表达,提高我们在科技类话题方面的语言能力。以下英文取自10月19日最新的一期Economist(经济学人)。

1、Since its birth in the 17th century, modern science has changed the world beyond recognition, and overwhelmingly for the better.

这句话首先使用since+n.的形式表示时间,随后是用了现在完成时,这种时态也是我们在雅思大作文写作中可以去使用的。

beyond recognition/imagination/doubt, beyond这种表达也非常生动形象,曾经在剑桥雅思的考官范文中出现过,也非常地道。   Overwhelmingly 压倒性地,非常好的一个词。

2、Modern scientists are doing too much trusting and not enough verifying—to the detriment of the whole of science, and of humanity.   the detriment of 有害,替换大家经常说的harmful这个词语。

3、Too many of the findings that fill the academic ether are the result of shoddy experiments or poor analysis. A rule of thumb among

biotechnology venture-capitalists is that half of published research cannot be replicated.

Either or这个词语放在阅读里想必没有人不认识,可是能够熟练地应用到写作中的学生就不多了,通过这个例句,希望大家可以学会使用这个非常棒的表达。

A rule of thumb 经验之谈

4、Even when flawed research does not put people’s lives at risk—and much of it is too far from the market to do so—it squanders money and the efforts of some of the world’s best minds.

it is too far from the market to do so 这个too far的表达也很地道,很多学生在写的时候只会用否定句,可以尝试使用这个表达。

Squander相当于waste 浪费的意思,可以用来指浪费金钱和浪费力气。

5、One reason is the petitiveness of science. In the 1950s, when modern academic research took shape after its successes in the second world war, it was still a rarefied pastime.

Competitiveness竞争力,注意与近义词petition 竞争区别,比如international petitiveness国际竞争力;

Take shape成型

6、Careerism also encourages exaggeration and the cherry-picking of results.

Careerism野心,事业心

cherry-pick 挑选

7、Conversely, failures to prove a hypothesis are rarely even offered for publication, let alone accepted.

Conversely,匡威,表示对比,与此相对的是,表示转折。   prove a hypothesis证明一个假设

let alone 更不要说…

8、Science still mands enormous—if sometimes

bemused—respect.

Enormous 巨大的,不要一想到多只会说lots of/many

9、But its privileged status is founded on the capacity to be right most of the time and to correct its mistakes when it gets things wrong. And it is not as if the universe is short of genuine mysteries to keep generations of scientists hard at work.

Privileged 有特权的

10、The false trails laid down by shoddy research are an unforgivable barrier to understanding.

False, shoddy,等词,全文一直在做替换,非常丰富,一篇优秀的雅思文章也要体现学生用词表达的丰富性。

以上就是雅思写作科技类的相关介绍,希望通过以上十个例句,可以让同学们对于科技类大作文的素材增加一些积累。另外,本文论证的也非常丰富,很多观点和论据非常新颖,最后祝大家都能考出好成绩。

作文五:《雅思作文科技类》7700字

科技类

2014年4月26日雅思写作范文(科技类)

题目:With the wide use of puters and the Internet, people can study and work from home without going to school or pany. Do the advantages outweigh its disadvantages? 解析    今天的题目考的是“利用网络在家学习和工作”。如果按照出题频率来说,这个题应该可以排到雅思考试的前三甲了。再加上小作文考的那个柱状图,4月26号考雅思的同学有福了。

好写的题目都有一个共同的特点,就是贴近大家的学习工作生活,容易想到很多的素材和理由。如果你在家工作,你就不用每天去挤公交和地铁,浪费时间不说,还把人折磨得身心俱疲(save a great deal of time and energy)。另外,时间安排会更灵活(have a flexible schedule)。只要你能完成任务(meet the deadline),不管你几点开工,很多人早上9点脑子还没醒过来,而到了晚上他们反而工作起来倍精神。对于学生,如果在网上上课当然也很方便,除了免去上学放学的辛苦,还可以把课程录下来反复听(review the course content many times),无论学霸学渣都可以按照自己的节奏来复习。

关于这种模式的弊端,主要有以下一些:让员工和学生都缺乏面对面的交流(face-to-face munication),变得比较疏远(bee alienated)。对于员工来说,少了老板的监督和约束(supervision and discipline),很多人可能发现工作效率会降低。也许你上下班路上省了俩小时,结果还不够你淘宝、聊天和打游戏的。家里的环境让人放松(relaxing),估计很多人都觉得在家里缺乏工作的氛围(atmosphere)。

最关键的一点是对于学生的影响。本篇范文用到了“剑8-1”的一些素材:学习的目的不只是学知识和获取信息(education is not about learning information and acquiring knowledge only),还需要学习与人相处(interact with their peers),学习尊敬老师(respect their teachers),学习遵守纪律(obey school rules),而这些都是远程教学(distance learning)所无法学到的。所以文章的结论是:在家工作和上课也许会变得越来越流行(popular),但是这种模式只适合某些工作,而且它永远不会取代传统的学校(replace conventional schools)。

2014-04-26 利用网络在家工作和学习

The advent (到来)of the Internet has made it possible for people to study and work from home. When we enjoy the convenience and flexibility of this new pattern, its negative influence should also be noted.

Working from home enables employees to have a flexible schedule. As long as they can meet the deadline, they can choose any time in a day to do their work without starting or finishing at a regular time, as they do in conventional panies. In distance learning, the course content can be recorded and replayed, which means students can review it as many times as they want. The most attractive part is that employees and students do not need to travel to the pany and the school every day, saving a great deal of time and energy.

However, this work pattern probably only suits some jobs that can be done on the puter such as designing, accounting, translation, etc.. Due to the lack of face-to-face munication, colleagues are likely to bee alienated, which may affect their cooperation. Another problem is the relaxing environment at home. Without discipline and supervision, some employees may find it difficult to finish their tasks on time.

The biggest concern is perhaps for students, whose education is not about learning information and acquiring knowledge only. When staying in school, students will learn how to interact with their peers, how to respect their teachers, how to obey school rules, etc. These elements are an

indispensable part of education, but they will be missing in distance learning.

To sum up, learning and working via the Internet is a convenient way and it is expected to bee more popular in the future. However, we should take other factors into consideration when we decide to work or study from home. In my view, this pattern will never replace

conventional schools.

2014年3月13日雅思写作范文(科技类)

题目:Some think that printed books are not necessary in the digital era, because all writing can be stored electronically.

Others think printed books still play an important role. Discuss both views and give your own opinion.

解析: 关于电子书的好处,大家应该比较容易想到。很多人在地铁里都是捧着电子书在看,所以它最大的好处是方便。联系到之前考过的电子图书馆,有很多素材都可以使用,包括节省空间、节约纸张和有利于环境保护。而且查阅电子期刊可以不用跑去图书馆,只需要在家里的电脑上就可以操作,这也带来了便利和高效。

这个题目的另一方可能稍微难想到理由,就是纸质书的优势。喜欢读书的人可能都对印刷的书比较有感觉,泡一杯茶、放一段音乐、捧一本书。这是一种阅读的享受enjoyable experience。此外,看电脑屏幕还有损视力。在存储一些重要的文件资料的时候通常也会使用纸质的材料,这样显得更正式一些。所以说,电子书的作用会越来越大,但是纸质书也不会完全消失。

2014-03-13 电子书vs纸质书

In the information age, electronic books have bee so prevalent that some people claim that printed books will disappear soon. However, other people hold a different opinion, believing that printed books still play an important role. This essay will discuss both sides.

Electronic books have obvious advantages in storing and disseminating information. They do not occupy large space as paper books do. For example, the whole library can be made available online and this kind of electronic library can save abundant land resources. Reading e-books is also much more convenient than the traditional way of reading. People can store hundreds of books in their mobile phone and take them for a vacation instead of carrying a heavy suitcase of paper books. Most importantly, e-books are environmentally friendly as they save a huge amount of wood resources used for producing paper. When our living environment is deteriorating, replacing paper books with e-books is of significance to the protection of the globe.

However, some people argue that printed books are still indispensable in our life and will never disappear. For many readers, having a printed book on the hand gives them an enjoyable experience of reading that is different from looking at the puter screen. Watching the screen for

too long is harmful to the eyesight, particularly for children. It is also worth mentioning that printed information plays an irreplaceable role in storing essential documents such as contracts and archives.

In my view, the role of printed books will inevitably diminish. In order to save resources and protect the environment, we should reduce the use of paper books and advocate electronic books. But printed books will not disappear because they also have their advantages.

2015年3月28日雅思写作考题解析与范文(科技话题)

题目:Some people think that using mobile phones and puters has a negative effect on young people's reading and writing skills. To what extent do you agree or disagree?

解析:

这是一个典型的科技话题,看似比较简单,但仔细一琢磨也不是那么容易。需要严格扣题。这个题只能写手机电脑对于reading和writing skills的影响,写别的素材就容易跑偏。如果怕字数不够,可以把它拆分来写,比如分别写手机和电脑,分别写对于reading和writing的影响,这样字数就能写得更多一些。

这篇文章的用词都非常简单,因为都是生活中大家熟悉的素材,比如打手机make phone calls、发微信send voice messages、发短信send text messages,这些都使人们没有机会去读和写,虽然发短信也需要读和写,但是那个文字太简单太口语了,大多是“笑脸”“呵呵”“lol”之类的。所以损害了年轻人的读写技能Undermine young people’s reading and writing skills.

电脑也是有害无益。小孩子用电脑打字的时候会不太关注单词拼写和语法,因为很多时候软件有自动纠错功能correct the mistakes automatically。虽然有人说电脑和网络使大家有

更多信息可以阅读,但你仔细想想,坐在电脑前面的人有几个在看文学作品的(literature)?大多数时候都在看八卦新闻,看奇闻异事,看优酷土豆,看。。。。。。

这篇文章我没有写明显的让步段,只是在两个主体段内部直接增加了一点让步反驳的内容,用词都非常简单。最后再一次提醒大家,考试的文章要自己写,注意逻辑,要扣题,不要把背过的素材一股脑往上搬,否则容易跑偏。考官的意图非常明确:限定写作范围,考察真实写作能力。这也代表了今后雅思写作考试的必然趋势。

2015-3-28 手机电脑损害年轻人的读写能力(科技话题)

Using electronic products such as mobile phones and puters has bee an indispensable part of our daily lives. Some people believe that the popularization of

affect young people’s

An important function of these munication tools is to enable people to interact with each other via sound and pictures. Such activities as making phone calls and sending voice messages and photos can be done on the mobile phone, which means people have fewer opportunities to read and write. Although some people still write text messages, the every reason to believe that using mobile phones may undermine young people’s reading and writing skills.

Another essential device in life is the puter, which has the same negative effect. When people write on the puter, they pay less attention to their spelling and grammar, as the mistakes can be corrected automatically with the help of Office Software. This is

particularly harmful to teenagers, who need to practice writing by hand the puter and the Internet provide people with more materials to read, the fact is that most of reading before the screen is about news and short passages. Fewer young people choose to read literature on books.

I argue that using puters and mobile phones have a negative impact on young people’s reading and writing ability. It seems unrealistic to ban the use of these devices among them, we need to encourage them to stay away from electronic devices for some time in their daily lives.

雅思作文科技类范文1:

题目:

Scientific and technological advances have changed our lives. But some scientists in some fields say that scientists are not able to find solutions to the problems they have created. To what extent do you agree or disagree?

范文:

We sure live differently from our parents did decades ago. The changes are wide and profound. At the same time, we are facing challenges and problems unknown in the past. Could we find solutions to problems created by scientific development? The answer seems to be no.

Some of the most obvious problems caused by technological advances lie in the IT industry. At a time when we did not have puters and electronic bank services, people took money with them and paid by cash. If they were stolen, only the amount they had with them was lost. But now credit cards are more monly used in shopping malls and other places, crimes again us have bee more serious and caused greater losses to people. A thief may tape the code of your credit card and make a copy of it. Then he could safely withdraw all your money from an ATM machine. Crimes such as this are very sticky to solve because there is no witness and the surveillance cameras give little help to the police.

Another example is the issue of information control with the media industry including TV networks and Internet that give easy access to information without discrimination to people’s age. This has created a huge problem for parents and schools because teenage people are particularly vulnerable to adult materials and information violent in nature. In the past, when most information came in the form of print, it was relatively easy to control what children read. When a parent put away a book unsuitable for children, they were cut off from the source of information. With puter parents could use software to filter bad web sites but could not prevent new ones from appearing every day.
