Match each of the headline (A-E) with the most suitable paragraph (1-5) below. A. How I began B. The worst aspect of my hobby C. My hopes for the future D. Why I like my hobby E.

In short, I play computer games. It's like entering a different world. That's why I love playing them so much ______ 2. I first became interested in computer games about 4 years ago. I was staying with my cousin for the weekend. He had some games and he taught me how to play them. I became hooked immediately! When I got home, I decided to save all by money for buying games. Now I've got about 20 different games. ______ 3. Some of my friends from school are interested in computer games too. We normally meet at my house in the evenings and play for a few hours. We sometimes play at weekends, but if the weather's good, I prefer to go cycling or play basketball instead. ______ 4. Computer games are interesting because they often contain stories and characters. The games are getting better all the time, but they're also getting more expensive. The only thing I don't like about my hobby is the cost! New games are often around $50. ______ 5. My interest in computer games has taught me a lot about computer graphics. I want to study computing at college, and learn how to design and program games. Eventually, I'd like to start my own software company, creating and testing new games.
