单项选择题

W: Why do we have to walk to the station And where is it
M: It’s just down that road, I think.
W: Look! There’s a policeman! Ask him the way.
M: All right. I’ll go and ask. (pause for 6 seconds)
W: So, what did he say
M: Well, we have to walk down this road, take the first turning on the left. Then walk until we come to the river and ...
W: The river
M: Yes. It’s over there, and there’s a bridge. Across the bridge, we will be able to see some road signs which will tell us the way.
W: But how far is it How long does it take to walk there
M: About fifteen minutes, if we walk quickly.
W: Fifteen minutes! We may be late for the train. And with these heavy bags, too! I think we ought to take a taxi.
M: Not at this hour. Look at the traffic. It’s moving very slowly. We can get there just as quickly on foot.
W: Well, I can’t possibly carry this bag any farther.
M: All right. Let me take it, then.
W: Don’t be silly. You can’t carry two bags at the same time.
M: Yes, I can. The bags aren’t that heavy...hmm!
W: You see! They’re heavier than you thought!
M: Perhaps it’s not such a bad idea after all.
W: What isn’t such a bad idea What do you mean
M: Taxi! Taxi!
