What's your favorite sport ?   It's hard to say . Perhaps swimming is my favorite . I like swimming because it helps improve my lung capacity . In the scorching summer days , there's nothing like a cool swim . Currently , I go to the pool twice every week .   Is the entrance charge expensive ?   Well , it costs an arm and a leg — 30 yuan per person . What a costly sport ! That is why I have to refrain from even thinking about it . And I find jogging a very agreeable substitute .   Haha , jogging ? Perhaps it might be a bit too boring ?
