　　We talked about the advantages and disadvantages of internet shopping these days. Some students think it's very convenient for us to go shopping on the internet. The shops on Internet ，for example taobao.com, 360buy.com are open for almost 24 hours a day, so we can buy something we want at any time if we like. What's more, we needn't to wait in a queue.

　　However, some students disagreed with them. We can't see the things while we are shopping. So we are not sure whether they are good or not.. Besides, we can't enjoy the happiness of shopping with our friends.
