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 businesses are run from one-room home offices. Others have hundreds of employees across the world. 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 on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my "e-commerceless" Web-surfing, not knowing about 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 $15 in all!" She said excitedly. "Everything on eBay is on sale! It's a 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. What's the purpose of the article? A) To tell the readers how he begins online shopping. B) To do business on the Internet. C) To make an online shopping ad. D) To advise people not to do online shopping

The first chocolate was eaten by people in Central and South America hundreds of years ago. In those days, people did not really eat chocolate; the cocoa bean was used to make a chocolate drink that the people enjoyed very much. Much later the cocoa bean was brought to Europe and people there also came to love the taste of it. In 1824, John Cadbury opened a small shop in Birmingham. One of the items he sold was cocoa powder to be made into drinks. In 1831, he opened a small factory to make cocoa powder from cocoa beans. John Cadbury believed that alcohol was an important cause of people's being poor, and he wanted to encourage people to drink chocolate instead. A few years later a man called Joseph Fry invented a way to make chocolate bars, and so for the first time people had the chance to eat chocolate instead of only drinking it. At first, chocolate was luxury and only the rich people could buy it. Later, as more and more chocolate bars were produced and sold, they became cheaper. However, at first, only plain chocolate was produced. Milk chocolate came later and this was made by adding milk or milk powder to the chocolate. Cadbury introduced their first milk chocolate bars in 1897. Their most famous chocolate, Cadbury's Milk Bar, was introduced in 1905. It has been a best-seller in Britain and around the world for nearly 100 years. The Cadbury factory is still in Birmingham and the chocolate produced there is eaten all over the world. Every year, thousands of visitors visit the factory to see how chocolate is made. John Cadbury wanted people to _ . A) drink more alcohol and chocolate B) drink less chocolate and more alcohol C) drink more chocolate and less alcohol D) drink chocolate instead of alcohol

Q: Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate . As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi. Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career. Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations. Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them. Aided by computers, Hoffmann was able to _ a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value. Why was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry? A) He established rules to predict chemical reactions . B) He succeeded applying computer science to chemistry research. C) He shared what he had achieved with another scientist named Fukui Kenichi. D) He succeeded in both chemistry and computer researches.
