听力原文：M: There's a letter here for you, Mum.
W: Thanks, John. Oh, no, not another telephone bill. I hope it is not as much as last time.
M: How much is it?
W: $130.94 for three months. How can it be so much? Tour father and I hardly make any calls. You must have been using the phone all the time.
M: Only to speak to my friends.
W: John, I don't think you realize just how much it costs when you telephone your school friends, and you speak to them for so long, especially during the day. Why can't you call them after 6 pm when it is cheaper. Your father is going to be upset when he finds out.
M: I'm sorry.
W: Well, being sorry just isn't good enough. I've told you often enough not to use the telephone so much. If you had to pay the hill, you wouldn't be so irresponsible with the telephone. You see your friends every day. Why do you need to phone them up as well?
M: But I do have something important to phone them sometimes.
W: OK, if you still take so long speaking to them, you'll have to pay half of this bill out of your wages from your Saturday job.
M: But Mum, that's not fair.
W: Then, I may have to get one of those phone locks and I'll keep the key, then you won't be able to make any calls.
