听力原文:W Hi, Sarah, it's Meg. I'm working on the presentation and I don't think I'll be able to finish my part by Monday morning. Do you think I could get an extension? W How much more work do you have left? W I've finished only 3 sections and I still have 2 more left to do. W Well, Jack hasn't been able to finish his part, either. It looks like we'll have to postpone presenting it to Ms. Lawrence until the end of the week. I'll let her know. What is Meg working on?
