Dialog A.
- Feeling tired?
- Yeah, I’ve been on the treadmill for half an hour already.
- You take your fitness classes very seriously, don’t you?
- I have to. I’ve put on five kilos after the last 2 weeks. Too many buns and cakes.
- Hmm, yeah, but if you exercise here regularly you’ll be in good shape really soon.
- I’m also thinking about going swimming a couple of days a week.

Dialog B.
- I’m dying for a drink!
- I thought you liked dancing?
- I do. But I need a break. Let’s have a drink and a sandwich.
- Ok. Chicken or tuna?
- Chicken. And a glass of mineral water, still.

Dialog C.
- So, what’s wrong with you?
- I don’t really know. But my foot hurts and it’s getting worse every day.
- When did you first feel the pain?
- Hmmm. 3 days ago. At first I thought it’s because of my intensive courses in my fitness club, I didn’t pay too much attention, but yesterday we had a party and I had to leave almost at once as it was difficult not only to dance, but to walk.
- Well, we'll have to x-ray your foot just to make sure everything is all right with the bones.

Dialog D.
- Where are we going now?
- To sport square!
- Gosh, you never done any sport!
- Right, so it’s a good time to start.
- Because you put on some extra kilos?
- Mainly. But also because it’s a mega sale in the sport square! I can buy everything in a half price!
