在广州这个改革开放的城市里，每天在路上你都可能遇上一个外国旅游者向你问路。作为这个城市的小主人，这时你就可以把学校里学到的知识使用出来，在外国朋友面前显露两招了。如果你是sally, 你会像她那样，礼貌地给旅游者指路吗?

　　(t is short for tourist, s is short for sally)

　　t: excuse me, i am a tourist from new delhi(新德里). can you tell me the way to sun yat-sen memorial hall?

　　s: well, the place where you want to go is far from here, you'd better catch the no.2 bus, and get off at the third stations; sun yat-sen memorial hall is in front of you. you can't miss it.

　　t: but where the bus-stops?

　　s: go down this road, turn left at the first crossing, and then go straight, you’ll find the bus-stops.

　　t: thank you very much!
