听力原文：W: Hello. This is the 911 Emergency. M: Help. Help. Please help me ! W: Yes sir. Please calm down and explain exactly what is happening. M: Calm down! My car is stalled on the freeway, I have a lady passenger, and she's going into labor. W: Now relax sir. Explain exactly where you are. M: I'm... I'm in the southbound lane of the Lincoln Expressway, about 15 miles from the Washington Tunnel, and this lady isn't going to wait. W: Okay. What's your name sir and your passenger's? M: It's... it's Bob, and I have no idea about the woman. She's in no condition to tell me. W: Okay, now what's the nearest landmark to your location? Pay careful attention. M: Umm, I see golden arches... McDonalds. W: Okay, is there anyone else with you? M: No, and I've tried to get someone else to help. [The sound of a bottle breaking.] W: Hey, what was that? M: Ah, someone threw a bottle at me. How soon can some- one get here? W: I've just dispatched an ambulance to your location. They should be there any second. M: Hey, is there anything I can do while we wait for the ambulance? W: Yes, uh, keep her calm and warm. M: Okay. Please hurry. Oh, they're too late. It's a boy! (20)
