This year I decided to do something to regain my good name as a kindly uncle. My 1 Tony,had never forgiven me for the dictionary I had bought him as a birthday present last year. His 2 had no reason to be thankful to me either,because the year before, I had 3 their dear son with a pot of paste(浆糊) and some funny pictures. Instead of 4 them into a book, Tony had naturally covered every wall in the house with them. This year, 5 , I decided to let him 6 for himself. We went into a big shop,but Tony was very particular about 7 . Although I tried to show him toy after toy,he was not to be 8 . Then I saw he suddenly became 9 ; he had discovered something he really liked: a large tin dram. I was quite happy too 10 I thought what Tony’s mother would say when she saw it. Nobody would get any 11 for weeks! I led Tony away 12 , saying that the dram was too expensive. Tony asked for permission to go off 13 and I made the most of my chance to sit down end 14 my aching feet. Fifteen minutes passed but there was still no sign of Tony. I began to get 15 and got up to look for him. I asked a young lady if she had seen a little boy in a grey suit. She looked 16 her helplessly and pointed out that there were so many 17 in grey suits. I was just going to call the police for help,when I saw a strange 18 dressed in strange orange clothes. He was wearing a false beard and had a caveman’s axe(斧子)in one hand,and a space gun in the other. It was, of course,Tony, who informed me 19 that he was the first 20 to fly into space.
