　　本文实际上是从客观公正的角度对比网上购物与传统购物。文章首先指出如今网络时代我们在网上无所不能，网上购物悄然受到人们青睐。随即围绕网上购物这一中心议题提出两种不同态度。一些人喜欢网上购物，他们认为与传统购物方式相比，它快捷、方便、省时，选择面大。实际上他们是拿网上购物的长处比传统购物的短处。而另一些人对此不感兴趣，他们对假冒伪劣产品十分谨慎，很怕上当受骗。这些人是拿传统购物长处比网上购物的短处，最后作者得出结论：网上购物势必会发展成不可抗拒的新的购物趋势。

First ,the web-stores can keep customers updated about the best selling products. Besides, they can provide customers with a wider range of choices. Most important of all , it is very convenient and time-saving .People can stay at home shopping whatever they want online.

　　However, others who stick to shopping in the real –life stores have their reasons. First, they argue that though time-saving, it’s a little bit complicated to pay on the Web. Besides, they think that customers can never rest assured of the quality of the commodities unless they see them with their own eyes. Finally, they believe the best way to be on guard against the fake and poor quality commodities is to shop in the traditional way. Therefore, they don’t show any interest in shopping online. However, more and more people will prefer shopping on the Web. And it’s believed that it will eventually be an irresistible trend of shopping in the 21st century.
