Hello, everyone! I'm Molly, a middle school student. I love watching movies very much because it helps me 1. There is a 2 near my home and I often go there. It is the best cinema in my city. It's 3 and there are a lot of movies to watch every day. But I need to 4 lots of rules. Let me 5 you some of them.
When I go into the cinema, I have to 6 my ticket (票). I can't take any food or drinks to the cinema, so I never buy anything outside the cinema. I can't take 7 in the cinema. I can't use my phone, either. If I see a 3D movie, I should get 3D glasses. And if I break (弄坏) the 8, I should pay for them.
I don't like these rules because I think they are 9. In my dream cinema, no one will tell me what to do or not to do.
