My favorite sport is swimming.

I feel cool when I am swimming.

I used to go to the swimming pool.

There's a 4 kinds of stroke about swimming.

It's called freestyle,breaststroke,and backstroke,also butterflystroke.

I like breaststroke the best.

The hardest stroke is butterflystroke so I do't like it.

Now I don't swim but when I grow up, I will swim for exercise.
