M: Come on, Julie, how’re we going to convince everybody that I’m the best candidate?
W: It won’t be easy!
M. Thanks a lot !
W: Oh, just kidding. Actually, I think once we show everyone how well you did as junior class treasurer, you’re sure to be elected president.
M: Well... What’s your strategy?
W: One thing I was thinking of is to hang campaign posters in all the hallways－
M: But everybody puts up posters. We need to do something different.
W: Let me finish: The campus radio station is willing to let you have five minutes tomorrow morning at seven to outline your plans for the year. Lots of students’ ll hear you then.
M: Great idea !
W: I’ve also arranged for you to give a speech during dinner tomorrow. Over a hundred students’ ll be  there. And you can answer questions after you finish speaking.
M: That means I’d better come up with a speech pretty quickly. How about if I write it tonight and show it to you after chemistry class tomorrow?
W: Fine. I’ll see you after class.
M: You’re really good at this. I’m glad you agreed to help me out.
