It’s fine to give negative answers in part 1 of the speaking test. Here are some example negative answers for people who don’t like sport:
1. What sports or physical activities do you regularly do?
Unfortunately I don’t have time to do any sports or physical activities because of my work commitments. I’d like to find more time for regular exercise.
2. Which sport or game would you like to be good at?
I’d like to be good at tennis. It must be great to be able to hit the ball as hard as you can and watch it land exactly where you wanted it to.
3. Do you prefer watching or playing sports?
I don’t watch much sport on TV and I’m not a big sports fan, so I think I would probably enjoy doing sports more than watching them.
4. Do you think children should be encouraged to do more sport?
Yes, I think that sport is really important for children. Sports and games teach children to play together and try their best.
