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!
