A、He is an expert of car sales. B、He is a mechanic of cars. C、He is the owner of the ear. D、He is an inspector. B[听力原文] What do

M: Hi, Mary.
W: Hi, Thomas. What’s happening?
M: Well, I’ve decided I have to get a car.
W: You’re going to buy a car? Do you really need one? I’d probably still be driving except that my car broke down last yean Instead of getting another one, I just moved closer to the university and went back to riding a bike—better for the environment, better for my health and 1 save a lot of money.
M: Did it really cost that much?
W: Well, when you think of insurance, rising petrol costs, parking plus maintenance and repairs, it adds up.
M: I know it’s going to be expensive but I really need my own transport. It takes half an hour by bus each way to university as it is.  But now I’m working at night in the city. There’s no way I want to hang around waiting for a bus late at night and then walk 3 blocks home alone.
W: Hey, I think you’ve got a point there. So what kind of car are you looking at?
M: It’s a 90 Ford. The owner is asking $2000.
W: That’s pretty old. How many kilometers has it done?
M: Oh, I forgot to ask. I’ll have to check tonight when I go to see it. Would you be able to come with me to have a look at it? At about 7 o’clock?
W: Sure I will, but I don’t know a lot about cars. I do know one thing, though.  I wouldn’t buy an old car without having a mechanic look at it first. Why not ask Joho to come with us since he is an expert in this field?
M: That’s a great idea.
