【简答题】
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? 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 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. 小题1:From the first two paragraph we can conclude that the author A．had no experience using computers B．had no idea of what e-commerce is C．only used the Internet to check e-mail D．thought surfing the Internet was a waste of time 小题2:The writer didn’t find out about e-commerce until A．he stopped web-surfing B．he visited a store in his backyard C．his friends told him about the online deals they made D．his sister explained the packages she got by mail 小题3:We can infer from the last paragraph that the author .
