A: Excuse me. Could you tell me how to get downtown( 市区 )?

B: Yes, of course. Are you familiar with the streets here?

A: No, I'm from out of town.

B: Well, let me see. Go to the end of this block （街区） , turn right, and walk six blocks. Then turn left for three blocks. There's a big intersection there. You can't miss it. The main business section is three or four blocks south of the intersection.

A: Thanks a lot. Oh, one more thing. Are there any buses running at this time of night?

B: No. They stop at eleven p.m.
