4 阅读理解。 I was in a strange city and I didn"t know the city at all, and what is more, I could not speak a word of the language. After having spent my first day in the town-centre, I decided to lose my way on my second day, since I believed that this was the simplest way of getting to know the strange city. I got on the first bus that passed, rode on it for several stops, then got off it and walked on. The first two hours passed pleasantly enough. Then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way. The trouble was that the only word I knew of the language was the name of the street in which I lived and even then I pronounced it badly. 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. The next person I asked was a policeman. The policeman listened to me carefully, smiled and gently 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 in the direction he pointed. About an hour passed and I noticed that the houses were getting fewer and fewer and green fields were appearing on either side of me. I had come all the way into the countryside. The only thing left for me to do was to find the nearest railway station. 1. The writer believed that if you wanted to get to know a strange city, ______. A. you should go everywhere on foot B. you should have a map C. you should ask people the way D. you should get lost 2. The newspaper-seller ______.

A. he couldn"t speak the language B. he followed the policeman"s direction C. he took the wrong bus D. he left the town-centre 4. The policeman ______. A. didn"t help him B. pointed at him C. didn"t understand what he really meant D. didn"t know the way
