Jack: What do you usually do on weekends? 
Wendy: I usually go shopping. 
Jack: I never go shopping. I can’t stand shopping. I usually take exercises 
Wendy: But I think shopping is a kind of exercise too. What exercises do you take? 
Jack: I prefer the indoor sports, like bowling, table tennis and karate. 
Wendy: How often do you playing bowling? 
Jack: About twice a week. And I’m taking a karate class from Hosa Health Club in Saturday morning. Would you like to come with me? I have an experience card. 
Wendy: That’s cool. I’d love to. I'm going to ice-skate in Saturday afternoon. Would you like to go with me? 
Jack: Sorry, I'm playing bowling in Saturday afternoon.
