【答案解析】[听力原文] 68-70 W: My feet are aching. I really shouldn't have worn high heels today. M: No kidding. Who knew we'd all be on a walking tour of the city before the meeting? W: I remember seeing a shoe store just around the corner from here. Do you think we have enough time to stop by? I honestly won't be able to walk back unless I get some relief for my feet. M: It should be fine. We can get you some shoes and then eat a quick lunch. We're almost back at the convention center anyway.
