1. A lot of things have changed in sports. Nowadays women often play football, but in the middle of the last century only men did it. These days athletes prefer metal tennis rackets, but they used only wooden rackets before. Modern footballers get a lot of money now, things were different before.

2. When you play chess, you move chessmen on a chessboard. But if you are a badminton player, you use a racket and a shuttlecock. Athletes in gyms use horses, rings, and bars. While boxing people wear boxing gloves. And certainly sportsmen and sportswomen use balls in all ball games.

3. I like sports. I mean to say that I like to watch different competitions and games on TV, but I don’t do any sport myself. I think you get a lot more excitement when you watch and see all the details than when you take part in the event but miss many things.

4. Last winter I spent a week at a skiing school. It was not much fun really. First of all, we had to get up at 6.30 every morning. That was terrible. Then we had to make our beds ourselves. At 8.30 the skiing began and it didn’t stop until 10.30, then we had a little break and skied till lunchtime. I was always tired.

5. The sport I like is skiing. I think it is the best sport of all. It is certainly more interesting and more fun to go skiing than to go swimming or do anything else. I also think that it’s great to do cross-country skiing. I’m not fond of downhill racing. It’s very dangerous.
