An old friend telephoned from the airport to tell me that he had arrived．I was still in the office at that time but I had got 1 ready for him to stay with me．I 2 him where my house was．I also told him that I had left the key under the doormat(门垫)．As I was going 3 late, I asked him to go into the kitchen 4 get something to eat and drink．
Two hours 5 my friend telephoned me from the house．At the moment, he said, he was 6 the music．He said he helped 7 to some cold chicken from the fridge and he was now drinking a glass of orange．I asked 8 he had reached the house without any difficulty．He answered he had not been able to find the 9 under the doormat, but luckily the living-room window by the apple tree was open and he climbed in．I was very 10 to hear all of this．There is no apple tree in front of my living-room, but there is one in front of my neighbour's．
An old friend from California was going to spend a few days with me．He called me from the station to tell me that he had arrived．I wasn’t able to leave the office，but I had got ready for his visit．I told him where my new house was and that I had left the key under the doormat(门垫)．Because I knew it would be very late before I could get home，I asked him to make himself at home and help himself to anything in the fridge．
Two hours later，my friend phoned me from the house．At the moment he said he was listening to some music after a nice meal．He had found two fried eggs，and had helped himself to some cold chicken in the fridge．Now he said he was drinking a glass of orange and he wished me to go back soon．When I asked him if he had any trouble in finding the house，he answered he didn’t find the key under the doormat．But the window by the apple tree was open and he climbed in through the window．I listened to this in surprise．There was no apple tree outside my window at all．But there is one by the window of my next door neighbor’s house！
