We arrived in Spain for the _36_ time a few weeks ago and I decided to buy a car because we had sold _37_ we had in England before leaving. Yesterday the _38_ office rang us to tell the car was ready. I had _39_ out a model like it before but as I was not yet used to _40_ in this city, my wife did not want me to collect it on my own, so we went _41_ to fetch it. We paid for the car and _42_ the papers. They told us there was enough _43_ to take us to a garage, where we could fill up. (加油)The nearest garage to the _44_ was about 100 yards away and we got there _45_ .But when I turned into the main road I suddenly saw a lot of _46_ racing towards me .I got out of their way as _47_as I could by backing into the garage once more and the man behind _48_ at me . “It’s such a _49_ to remember to drive on the right, isn’t it?” My wife said.“Yes, if only I had _50_ a few lessons for practice,” I replied . “You’d better go carefully on the way_51_ ,” my wife said. “You ’d be _52_ if you had an accident _53_ the first day, wouldn’t you ?” While we were talking, the man behind _54_ out of his car and said in good English, “Would you mind telling me when you are thinking of leaving , _55_ are you going to sit in your car all the day?”
