We arrived in Spain for the first time a few weeks ago. I decided to 31 a car because we had sold the one we had in England before 32 home. Yesterday the sales office rang us to say the car was 33 . I had tried out a model like it before, but as I was not yet 34 driving in this city, my wife did not want me to collect it 35 so we went together to 36 it. We paid for the car and 37 the papers. They told us that there was 38 petrol（汽油）to take us to a garage, where we could fill up. The 39 garage to the office was about 100 yards away and we got there 40 .But when I turned into the main road I suddenly saw a lot of cars racing 41 me. I got out of 42 as fast as I could by backing into the garage 43 and the man behind 44 me.
"It’s such a problem to 45 to drive on the right side, isn’t it?" my wife said. "Yes, if only I had had a few lessons for 46 ," I replied. "You had better go 47 on the way home," my wife said. "You' d be sorry if you had 48 on the first day, wouldn' t you?" While we were talking, the man behind got out of his car and said in good English," Would you mind telling me 49 you are thinking of leaving? 50 are you going to sit in your car all day?"
