听力原文:W: (22)Good morning, sir. What can I do for you?
M: (22)Hi, I'm looking into getting some furniture and other items moved from the storage into my new home.
W: All right. How far away from the ware house is your home?
M: Only a few hundred yards, but the items are rather large and heady. I was studying overseas for the past two years and just recently returned, so while I was gone I had to put all of my furniture and other major possessions into storage.
W: OK, I just need to get some details first. What kind of house is it?
M: It has three rooms.
W: And how many entrances does it have?
M: Hm, is that actually relevant?
W: (24)Yes, because it usually affects the cost of the labor. It's easier to move items into a house with more entrances. So, the overall time and cost of labor will be cheaper.
M: Well, I hadn't thought of that before. (23)Hm, it has two, no, wait, three doors.
W: OK, three doors. And the location?
M: 1966, Finch Ave.
W: All right. And what are the items you want to move on the first trip?
M: (25)I suppose I'd like to get my bed and refrigerator moved in first. I've got some chairs and my kitchen table and dining set. I want them to be in the house earlier, too. As to the valuables, I think I can move them on my own.
W: No problem. Now we just need to get the weight of each item and then I can tell you how much the cost is.
