题型:阅读理解

     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(主人) 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?

     My friends often said they got cheap textbooks off Amazon.com, or had a good deal(交易)on Steve Madden boots that were on sale at SteveMaden.com. Unfortunately for me, I continued my

"e-commerceless" Web-surfing, unaware(不知道)of all the deals I was missing out on.

     That is, of course, until my sister finally sold the idea to me.

     "Why are all these packages(包裹)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 $15 in all!" She said excitedly. "Everything on eBay is on sale! It's way better than

going to the mall."

     I felt as if 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.
