听力原文：W: I've been standing here since half past six! Where have you been? M: I'm terribly sorry I'm late for about an hour, but I just couldn't help it. I got here as soon as I could. W: Well, it's not soon enough. The opera's already started! M: I know and I'm sorry. W: It's really very well saying you're sorry but you know I've been waiting to see it all month! M: Look, just give me a chance to explain, please! W: All right. M: I was all ready to leave the office when my sister called round. Really hysterical! So I couldn't just rush off without a word. W: Go on! M: I invited her in and she told me that Jack--that's her boyfriend--had been knocked down and was seriously injured. So I stayed with her until she calmed down. Than I came here as quickly as I could. W: I see. M: I'm sorry. W: But you could have phoned me or sent me an SMS. It wouldn't have taken a minute. M: I did try, but your mobile phone just powered off. I am sorry about the play. I know how much you wanted to see it. W: Well, never mind. We can always see it some other time. M: Yes, of course we can. W: I'm sorry for the way I snapped at you. M: I understand. I'd have been just as angry in your place. What was the woman doing at 7: 00 p.m. ?
