     I was concentrating on my work when my friend called me saying he was coming to visit me. After

explaining where my new house was, I told him that I had left the key under the doormat, which helps

preventing the floor from being dirty. Since I knew it would be quite late before I could get back, I suggested

that he make himself at home and help himself to anything that was kept in the refrigerator（冰箱）. 

     Two hours later my friend phoned me from the house. At the moment, he said he was listening to some

of my records after having had a nice meal. He had found the pan and meat in the refrigerator. Now, he was

drinking a cup of tea and hoped that I would join him soon. When I asked him if he had any difficulty finding

the house, he answered that the only problem was that he had not been able to find the key under the doormat,

but luckily, the living room window by the apple tree had been left open and he had climbed in through the

window. I listened to all this in great surprise. There is no apple tree outside my window, but there is one by

the living room window of my next-door neighbor's house！
