“随着科学技术的飞速发展……”

各位同学想必对这样一个文章开头十分熟悉。科技的发展与我们的日常生活息息相关，给我们带来了诸多便利，同时也造成了一些问题。今天我们就来看看雅思大作文中科技类话题的主体段落该如何写作。

例题展示

Human society has made great technological progress in the last hundred years. Some people think this has had more negative effects on people’s lives than positive ones. To what extent do you agree or disagree?

解题思路

这一道题需要我们探讨科技进步带来的积极影响与副作用，我们可以选择一个好处大于坏处的立场。

科技进步的事例

谈到科技进步的利与弊，我们首先来看看身边有哪些常见的例子。

汽车、飞机等交通工具：vehicles like cars and planes

生物科技：biotechnology

自动化：automation

人工智能与机器人：artificial intelligence (AI) and robots

互联网：Internet

首先我们来看看科技进步会带来什么样的危害

自动化技术的使用会让很多企业开始裁员find their staff redundant

失业率上升unemployment rate

互联网的广泛使用让人们失去面对面交流的机会 face-to-face interaction

产生孤独感 a sense of isolation

因为我们站的立场是利大于弊，在论述弊端的时候我们就可以使用一个让步段的结构。

Admittedly, there may be several disadvantages to technological progress. Once automation has been widely used, companies may find their staff redundant. This means that many workers may lose their jobs, and the unemployment rate may increase. In addition, people who spend a large amount of time surfing the internet will lose the opportunity of face-to-face interaction. Therefore, they may feel a sense of isolation. However these problems can actually be tackled. For example, technological innovation can create new industries that can provide more job opportunities, and various social media can offer netizens the chance to chat with people all over the world.

那接下来我们再来看看科技进步带来的好处

谈到科技进步的好处，我们可以从这些方面来考虑：

推动经济社会发展 promote social and economic development

自动化能够让产品生产更快速和低价produce goods much faster and cheaper

各种不同的交通工具让远距离运输更加便利 make it convenient to transport products for a long distance

推动物流业的发展boost the development of logistics

提高人们的生活质量 improve the quality of people’s life

生物科技领域的进步有助于治愈很多重大疾病，延长寿命 cure serious diseases and improve life expectancy

互联网的出现让人们更方便、更低廉地与他人交流easier and less expensive to communicate with each other

在第二个主体段我们就可以从这些方面论述科技进步带来的积极影响。

On the one hand, technological progress has brought about several positive changes in promoting social and economic development and improving the quality of people’s life. As for the former, production efficiency has been increased dramatically. Automation can help produce goods much faster and cheaper as the machines can keep working for 24 hours a day. This is not possible for workers who need to rest. Besides, the wide use of vehicles such as cars and planes contributes to the rapid development of logistics, making it convenient to transport products for a long distance. In terms of the quality of people’s life, key breakthroughs in biotechnology has brought about medicines that can cure serious diseases, thus improving life expectancy. Moreover, the public has benefited from Internet, finding it easier and less expensive to communicate with others.

以上就是科技这把双刃剑的积极作用与负面影响，各位同学你们记住这些观点你和表达了吗？
