On the night of the play, Jack was at the theatre early and he was already dressed in a policeman’s clothes long before the end of the first scene. He certainly looked the part all right, he thought as he    37    himself in the mirror. He even thought of going out into the street to see    38    he could pass as a policeman out there. Just for fun, of course.
Then he suddenly felt nervous. After all, it was his first time to    39   a part in a play. How could he face all those people   40    the play? He put his head in his hand and tried to    41   his lines, but nothing came to his mind.
A knock on the door made him look    42   . He was to go on stage in the second scene. “Have I   43   my part and ruined the play for everybody?” he
thought to himself, but it was only the manager. She    44    how nervous he was and suggested he should stand near the stage    45    he could watch and follow the play. It was a good   46    of getting rid of his nervousness, she said. She was right--- it seemed to    47   . In fact, the more he watched the play, the    48   he felt himself part of it.
At last the    49   came for him to appear on the stage, but suddenly the manager came to him again, looking worried as she placed a hand on his arm to    50    him back. “Has anything gone wrong?” Jack asked. “I’m afraid you’re going to be    51   ,” she said. “They have jumped three pages of the play and have missed your part out completely.”
