Technology Is Changing Our Lives
The fact that technology is changing our lives is undeniable.
First of all, technology makes life easier. With the invention of various electric home-appliances, housework is no longer a drudgery. With the innovation of assembly lines workers do not have to struggle with splitting lump of wood or iron. With the emerging medical treatment or therapy, the handicapped can lead a better life. With new vehicles coming into being, say, subway,mag-lev, spaceship, countries and continents are bridged and a trip to the moon is no longer a dream. Unquestionably, technology increasingly facilitates our lives.
Moreover, technology offers us more fun. On the one hand,with generations of new technology, people have more leisure time to enjoy their lives because the introduction of new technology speeds up productivity, which in turn leads to reduction of working hours. As a result time to relax after work is no more a luxury. On the other hand, means of entertainment becomes diverse. You can travel around the world as you wish with the new means of traffic springing up or you can enjoy yourself sitting comfortably in front of your TV set, which opens to you a new vista of the outside world. It's a wonderful life, isn't it?
It is true that new technology renders our life easier and more pleasant, but as is so often pointed out, technology is a two-edged sword which can be used equally for good or evil the other side we are often blind to. While polymer can be turned into throw away plastic and flashy bags, it also threatens our environment with sc-call "white trash". While Internet facilitates our communication, it gives rise to increasing net crimes. Being addieted to computers stifles the very creativity of human nature.
In conclusion, while we enjoy the freedom and convenience brought by high tech, we must be alert to its side effect. The only thing we need to remember is that we should control technology instead of allowing ourselves being controlled.
简 评 （科教论文网 lw.NsEac.com编辑整理）
本篇的主题是科技改变生活，其影响有正面的，亦有负面的。文章脉络清晰，可分为三个部分：科技给生活以便利；科技给生活带来乐趣；滥用科技会给生活带来威胁和损害。作者以忠告结束全文：科技不可避免地改变生活，关键是人们要支配科技而不是被科技所支配。
本篇文章的可取之处主要有两点。首先，文章的脉络清晰。保证一篇文章成功的前提是具备全面、简明的中心思想以及与主题息息相关并互相关联的主题句。主题句可以直接陈述或以含蓄的方式体现在每个段落的开首或末尾。另外，总结性的结尾是一篇文章完整的体现。其次，本文运用了大量的平衡句。平行结构有两种句型：一种是对照句即用相同的结构表述两种截然不同的思想；另一种是平衡句即用相同的结构表达两种相同或相似的思想。本文第二段就包含一组平衡句，如"With the invention ofvarious electric home appliances，housework is no longer a drudgcry．With the innovation Ofassembly line workers do not have to struggle with splitting lump Of wood Or iron．With the emergmg medical treatment Or therapy，the handicapped can lead a better life．With new vehicles coming into being，say，subway，maglev，spaceship，countries and continents are bridged and a trip to the moon is no longer a dream．”，该组平衡句在内容上相辅相成，语气贯通，较好地表达了“科技给生活带来便捷”这一主题句。另外，在第三段的结尾，作者运用了附加疑问句，如“It'sawonderful life，isn't it"，以期获得读者的呼应和共鸣。
