1. In the good old days, business was pretty simple. I had a pig, you had some wool; we showed up at the market and haggled ( 讨价还价 ), then I went home to knit a cardigan （羊毛衫） while you wanted some barbecue. Nowadays we don't have to show up at the market, and we don't even need physical goods or currency to conduct business. E-commerce is the most recent step in the evolution of business transactions. It replaces the swapping of money or goods with the exchange of information from computer to computer.

2. Information on advantages and disadvantages of e-commerce is attractive, because it reduces the cost of doing business. Sending a few bytes of data over a network is cheaper, faster and more convenient than sending a messenger or even making a phone call. The primary concern is issues in e- business security. The Internet is very public, and many people hesitate to send sensitive data over the wires where it might be intercepted （截获） by nefarious （恶毒） third parties. But with so many organizations excited about the benefits of e-commerce, plenty of people are working on resolving the e- security issues. 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 commodities 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 mouse. The commodities they order will be delivered to them promptly.

4. For example, if you want to shop on www.taobao.com which is the most popular website in China, there are four steps to complete the job.www.taobao.com At the beginning, you should register( 注册 ) on this website such as the name, address and some other basic information. Then searching your want- goods on the website, many stores selling your want-goods will lay out on the screen. You'd better choose some stores to compare and get the most convinced and cheapest one. If you have chosen the best one, you'd better chat with the shopkeeper. On the one hand, you can ask the shopkeeper some questions about the quality, bring down the price and deal with the way of post; on the other hand, if you buy more than one thing in one store, you should ask the shopkeeper to change your postage to one because the standard of postage is order not weight.

5. After you have reached an agreement with the shopkeeper, you can pay for it. There are three ways you can choose. One is postal remittance, the second is online banking and the last is Zhifubao. But I should remind you to remember that this step isn't pay the money to the shopkeeper just pays to the website until you get the goods. Then you just need to wait your order. But when your express delivery is reached, you should check the goods in it whether round before you sign for it.If the goods are ok, you should finish the next procedure to change the shopkeeper and grade the shopkeeper according to the goods and services. If the goods are damaged, you can deal with the shopkeeper to change a new one and let him charge the two-way postages or you can apply for a refund. In fact, shopping online is not a difficult job. Just like shopping in the center mall, practice makes perfect. The most important is just having more experiences.
