With the development of the Internet and the popularization of computers, shopping on the Internet has become a commonplace in our life. Here consumers can buy almost everything they need.
随着因特网的发展和计算机的普及使网上购物在我们的生活中日渐普遍。在这里消费者几乎可以买他们需要的所有东西。
Shopping on the Internet has a lot of advantages, of which the most important is perhaps its convenience. People don't have to waste a lot of their energy and precious time to go from one shop to another to choose the commod【纵览全球英语资讯、洞察全球英文信息，尽在英语翻译学习网（enfanyi.com）你的全球英语指南】ities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person. The goods come in all shapes, sizes and colors on the Internet. All they need to do is to sit in front of their computers and click the mouses. The commodities they order will be delivered to them promptly.
网上购物有很多优点，其中最重要的也许就是方便。人们不必浪费太多的精力和宝贵的时间去从一个商店到另一个来选择他们喜欢的商品。对于老人病人和忙碌的人来说是特别可取，因为他们不能亲自去商店。互联网上的商品有各种形状，大小和颜色。他们所需要做的就是坐在电脑前，点击鼠标。他们订购的商品将会及时的送给他们。
However, shopping on the Internet also has its disadvantages. The first disadvantage is that the consumers can't see the goods or try them on personally. Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered. They will never deliver anything to you after they get the money from you. Once cheated, you will find that you have nowhere to go to complain.
然而，网上购物也有它的缺点。第一个缺点是消费者不能看到商品或亲自试一试。有时候，真正的商品可能会和他们在电脑上看到的不一样。第二个缺点是有些互联网上的商店是没有注册的。从你身上得到钱后他们不会给你送任何东西。一旦被骗了，你会发现你无处可抱怨。
