Before 2002，nearly everybody knew that Wang Tao was the first Chinese to take part in a World Expo（博览会）．Wang Tao，a writer from Jiangsu Province，took part in the 1867 Paris World Expo and wrote an article about his experience．

    But at the end of 2002，some people in Shanghai were surprised to find that the first contact（接触）with World Expo actually happened 16 years earlier-in 1851，a man called Xu Rongcun took part in the first World Expo ever, the London World Expo．

    Xu Rongcun was a businessman who sold silk（丝绸）and tea in Shanghai．In 1851，when the United Kingdom announced that it would hold the first World Expo，Xu Rongcun thought it was a great chance to show his silk to the world．He sent 12 bags of “Huzhou Silk” to the United Kingdom．

At the beginning of the Expo，the people didn't pay much attention to Xu Rongcun's silk．However because of its excellent quality, the silk won gold and silver medals at the Expo in the end．

If there were no World Expo，Xu Rongcun might just be a successful businessman．But his experience at the first World Expo engraved his name on the history of World Expo．

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.
I’ve always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook. Myspace---I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online business are run from one- room home offices. Others have hundreds of employee(雇员)spread across five different continent. Have you ever heard of Amazon. com, Yahoo. com?

“Why are all these packages arriving in the mail for you, Katy?” I asked her one day. Strange envelopes had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this coat?”
“Oh, only about $15in all!” She said excitedly. “Everything on eBay is on sale! It’s way better than going to the mall.”
I felt as if my entire life, there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.
