听力题 An old friend from abroad, whom I was expecting to stay with me, telephoned from the airport to tell me that he had arrived. I was at the office at the time, but I had made arrangements for his arrival. After explaining where my new flat was, I told him that I had left the key under the door-mat. As I was likely to be home rather late, I advised him to go into the kitchen and help himself to food and drink. Two hours later my friend telephoned me from the flat. After the moment, he said, he was listening to some of my records after having just had a truly wonderful meal. He had found a pan on the gas stove and fried two eggs and had helped himself to some cold chicken from the refrigerator. Now, he said, he was drinking a glass of orange juice and he hoped I would join him. When I asked him if he had reached the flat without difficulty, he answered that he had not been able to find the key under the door-mat, but fortunately the living-room window just by the apple tree has been left open and he had climbed in. I listened to all this in astonishment. There is no apple tree in front of my living-room, but there is one in front of my neighbor''s.
