听力原文：M: Well, Sally？ Why do you look unhappy？

W: Oh, Hill, I have just had a quarrel with Mr. Smith.

M: Mr. Smith! What on earth was it about？

W: Well, I have made three bad mistakes so far this week. Today I forgot to give him an important message, so he got very angry with me.

M: But I don' t understand. You are usually very careful and never make mistakes.

W: I' m just so tired. I don' t know what I' m doing.

M: Why？ Have you been going to bed late these days？

W: No, I' m usually in bed at about eleven. But I' ve been woken up at about half

past four every morning. And then I cannot go back to sleep again.

M: Why？

W: It' s my new neighbor, the milkman next door. He gets up at half past four and he always turns the radio on loudly.

M: Ask him to turn it down then.

W: It' s difficult. I don' t know him yet.

M: If you don' t want to see him, write him a letter.

W: Do you think it' s a good idea？

M:Yes,I do. I' ll help you write the letter.

W:OK. Let' s try.
