One day, some children were playing hide-and-seek（捉迷藏）happily. In front of the  31  , Jim found the door of the letter box was   32   and climbed in. He   33 closed the door. When he knew   34  he had locked himself in it, he began to  35  help, but nobody could   36  . He was  37  and began to cry. At that time, his sister was   38  for him. She happened to hear him. She , of course, wasn’t able to open it.
　　When the  39  helped him out, he couldn’t keep back his tears. He had been in the box for nearly an hour.
　“Don’t forget  40  a stamp on yourself next time,” said the postman.
