听力原文:M: Sally, were you able to get that report all typed up.
W: Not yet, Mr. Black. Mrs. Famsworth asked me to type some letters for her. I'll be finished pretty quick and then I'll start on that.
M: Don't forget I need it in the morning. I have to take it along to Chicago to the regional meeting.
W: Don't worry, I'll get it done. My husband's on a business trip too. He's in Detroit today, and tomorrow he'll be in Boston. So I'm planning to stay late. After it's typed up I'll leave it on your desk. I should be finished by 8:00.
M: I'm sorry to make you so late.
W: It's all right, Mr. Black. Really, I don't mind at all. Besides, I can make a little extra money. My husband's birthday is next month. I want to buy him a new watch.
M: What kind are you going to get for him, a Bulova?
W: No, I thought I'd get a Rolex. or an Elgin. I don't really know much about watches.
M: I've got one of those Seiko digitals. I really like it.
W: Do you think my husband would like one like that?
M: I'm sure he would. The only problem is that they're a little bit heavy.
W: If they're that good, I think I'll go ahead and get him one.
M: Well, at least he won't get a tie. That's what I usually get.
W: Remember, it's the thought that counts.
