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.
