Mary: It’s eight o’clock now.Why did you get back so late today?
Alan: The buses were     crowded during the rush hour that it took me a long time to get on a bus.And then my bus   (get) stuck in the traffic jam.
Mary: I’m sorry to hear that.
Alan: What      buying a car now?
Mary: Do you really think       necessary?
Alan: Yes, quite necessary.You see, every day I have to spend a long time      (travel) on the road so that I can get to work on time.If I have a car, it will be much      (easy) for me.
Mary: You have a point there.But I don’t think we have enough money to buy a car yet.
Alan:    not borrow some from the bank? We can pay back money every month.
Mary: But we still don’t have a parking space for parking a car if we have one.
Alan: We can just park it by the road      most people do.
Mary: Oh, forget it! There are too many cars by the road and there’s no place for a new car now.
Alan: That’s really     problem.
Mary: Anyhow, I suggest we      (wait) some time until we have enough money for a car.
Alan: Well, we’ll have to.
