Read the text MY VISIT TO THE CINEMA I really enjoy going to the cinema; it is one of the favorite pastimes even though I don’t really go there often. Fortunately, the cinema is not too far away from where I live and I can get there by bus within ten minutes. I am very lucky to live in a big town because it means that I have a choice of cinemas and a wider choice of films. Watching films is always very relaxing and entertaining. The convenience of the cinema is that you can choose what time you want to go because there are usually a number of showings. You know, it is popular to go out somewhere first and then go on to a late- night movie. The cinema is particularly popular among students because they don’t have to pay full price for some films and is therefore a reasonably cheap form of entertainment. There are a variety of films available today. I especially like comedies or love stories. Detective stories with a lot of action and suspense grab my attention also. I particularly enjoy films where you become so involved with the story that you forget you are sitting in a cinema. The last film I went to see was an American comedy (Thriller called "Who's Watching the Baby-sitter?"). I really enjoyed it because it was funny, it had a lot of action in it and the end was so unexpected. Nowadays cinemas are so comfortable that it is almost like being at home so it is a luxury to go to the cinema. TRUE / FALSE 1. I often go to the cinema. 2. I am so happy that I live in a town. 3. Students don’t like going to the cinema. 4. I don't like detective stories. 5. The last film I saw was not interesting. 6. It wasn't predictable. 7. Cinemas are uncomfortable today. 8. My favorite type of fims is comedy. 9. I like going to the cinema in the afternoon. 10. It takes me a lot of time to go to the cinema. 11. We can watch different types of films in our cinema. 12. Going to the cinema is not cheap for the students. (3 points)
