听力原文：W:Hmm，hi．
M:Hi，I am going door to door tonight to tell students about the latest proposal of our Club．Do you have a few minutes？
W:Sale．You know，[7] I think I read something in the poster last week.
M:Yeah，[8] we ate trying to protect and conserve some of the open spaces on campus.
W: That's right. You are the group that's opposing the extension of the parking lot next to the student's gallery, right？
M: That's us. We just feel it is important to save some of the natural beauty of the campus. We are organizing a rally on Thursday afternoon to get the administration to reconsider the parking lot plan.
W: [9] Well, I have a class on Thursday afternoon.
M: But maybe you could sign this petition. We're going to submit it to the administration to demonstrate how the students feel about this.
W: [10] Sure, let me get a pen and I'll sign it.
M: I have a pen right here. And let me leave you this pamphlet about our club. Maybe you could come to some of our meetings. We get together once a month.
W: Yeah, I'd like to know more about your group. Let me know when the next meeting is and I'll try to be there.
