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 computers 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 commonly used in shopping malls and other places, crimes again us have become 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

computer parents could use software to filter bad web sites but could not prevent new ones from appearing every day.

People are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. Even with the little progress we have achieved, we find ourselves defeated by new problems with greater complexity and in wider scope.

In conclusion, developments in many fields of our life have brought us both benefits and problems. Developments in the banking industry give us greater convenience but making us targets of computer-based theft. Changes in media industry expose young people to inappropriate information difficult for parent’s control. However up until now, we have not successfully found permanent solutions yet.

Mobile (cell) phones and the Internet play an important role in the way in whichpeople relate to one another socially. Is this a positive or negative development? What is your opinion?

Give reasons for your answer and include any relevant examples from your own knowledge or experience. Now that you are benefitting from the use of the mobile phone and the Internetas social media as well as social interaction, could you imagine what your daily liveswould be like without these inventions ? Living in this age of information technology may be a blessing, but there seems an undesirable feeling under disguise. For that matter, probably what you like would be social connectivity and what you dislike might be personal anxiety.

It is a positive development that people have found it so easy to relate to one another electronically and share instantly in the social context. As technology has advanced, so has the need to remain contact with friends, family and loved ones. Through digital networking, the cell phone and the Internet have opened doors to the current generation's lives, as previously unheard of. While it goes without saying themany benefits that the Internet has to offer, the latest hand phones are well-equipped with high end features catering to a variety of communication needs from voice calls to text messaging. Apart from being able to help connect people anywhere andanytime, new handsets of innovative technology boast cutting-edge functions

designed to upgrade work performance and provide fun factors, all at your fingertips.Besides, what do you have to say about Facebook, Twitter and Google+ that are out there on your computer screens or on your smart phones?

Nevertheless, the heavy use in social networking of the mobile phone and the Internet causes anxiety, not to mention the negative effects produced by possible radiation. Chances are that these gadgets are getting you on nerves. It is not so much because of such networking devices keeping you on alert 24/7 as because of the

thought of being without them sometimes. So, there are feelings of increased anxiety during the absence of social mobility, as if when you were psychologically alone in the

middle of nowhere. And yet, once people being connected, it appears to be no end of interactive communication, particularly when driving, for instance. In this case, the epidemic of people using cell phones to talk and to send text messages via the Internet behind the wheel could give rise to more of a hazard than drunk driving.

As long as social interaction is concerned, it may be said that the hi-tech mobility is like a useful gift from heaven rather than a psychological disease from hell. The benefits of social interaction through the cellular and the Wi-fi seem indeed too good to be blamed. Whatever, there is no turning back to the age of B.C. (BeforeComputer).

 

第二篇：雅思写作素材之科技类

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。 20xx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

communication. 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 competitiveness 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competition 竞争区别，比如international competitiveness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 commands 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。
