W: Nick, here you are! I’ve been looking for you everywhere.
M: Susan, look at you. You are out of breath. What’s the matter?
W: Have you heard of the hip-hop dancing competition?
M: Yes, of course. Everybody has been talking about it recently.
W:(19)Look at what I’ve got. A registration form. You are such a wonderful hip-hop dancer. Why don’t you take part in it?
M: Oh, actually, I don’t care much for the competition.
W:(20)But you enjoy dancing so much and you make a habit of practicing every day.
M: Well, dancing is one thing and the competition is another.
W: Come on. What’s the big difference?
M: I only do hip-hop with friends. I don’t feel like dancing in front of a huge group of strangers, not to mention being on TV and seen by thousands even millions of people. It’s quite something for me.
W: I see. But I still think you should be part of it. You can meet more people who also love hip-hop in the competition and make more friends.
M: The final examination week is coming, too. I don’t think I should spare any time on this competition at this moment.
W: The final examination is important.(21)But the competition won’t begin until two weeks after the final exams. You can practice during that time. Why don’t you take the form with you and talk with your hip-hop friends? You don’t have to make the decision now.
M: Thank you, Susan. I will think about it carefully.
W: But remember, the deadline for registration is one week before the final exam begins.
