2 a) Read the first exchange of the dialogue. Where are the speakers? Listen, read and check. Dan: Hi, Jo. What’s your dad doing? Jo: He’s installing an alarm system. Dan: What for? Jo: Well, there are burglars around here. They’re stealing things from people’s houses. Dan: Really? Jo: Yes, you should tell your parents. Dan: You’re right. They should probably install an alarm, too. Jo: And you should be careful with your keys. Don’t lose them, or leave them near an open window. Dan: I didn’t think of that. Jo: You know there’s a lot of crime in cities these days. Dan: I think you’re right. We should be careful. Jo: Yeah, better safe than sorry!
