I stopped to ask a friendly looking newspaper seller.he smiled and handed me a paper.I shook my head and repeated the name of the street and he put the paper into my hands.I had to give him some money and went on my way.Then I met a policeman.I asked him at once.The policeman listened to mecarefully,smiled and took me by the arm.There was a strange look in his eyes as he pointed left and right and left again.I thanked him politely and began walking on. About an hour passed and I found that the houses were getting fewer and fewer and green fields could be seen on either side of me,I had come all the way into the country.The thing left for me to do was to find the nearest bus station. 1、when did the writer get on a bus on the second day ? 2、what was the writer's problem?
