An old friend from the US,whom I was looking forward to staying with,telephoned from the airport to tell me that he had arrived.I was still at the 41 at that time,but I had got everything ready for his arrival.After letting him know where my house was,I told him that I had left the 42 under the door-mat（门垫）.43 I was likely to be home rather late,I told him to go into the 44 and help himself to food and drink.
Two hours later my friend 45 me from the house.At the moment,he said,he was listening to some of my records after having just had a truly wonderful 46 .He had found a cooker and 47 two eggs and had helped himself to some cold chicken from the ice box.Now,he said,he was drinking a glass of orange juice and he hoped I would 48 him.When I asked him if he had reached the house without difficulty,he answered,“I was not able to find the key,49 luckily the living-room windows just by the apple tree were left open and you know what I could do.”
I listened to all this in 50 .In front of my living-room there was no apple tree at all.
