    In the middle of the night, Peter's wife suddenly became ill. She couldn't help crying, "Oh, my stomach! Get the doctor!"

    Peter, awaking from a deep sleep, thought his wife was only having a 1dream.

    "Stop that noise," he said to her. He turned over and tried to go to sleep again, but his wife still cried out, "Oh, help! Help! I'm sure I'm dying."

    Peter got out of bed and started dressing, but he could not find him any 2.

    "Where is my shirt?" he asked. His wife was too 3 to tell him, and she could only cry, "Oh, my poor stomach!"

    As soon as he had put his clothes on, he said, "Now, my dear, are you quite certain that you need the doctor? Surely you can 4   until morning, can't you?"

    "No, I can't. Go, go, go," his wife shouted, "or you will find me 5 in the morning."

    So Peter went out into the 6 street. He had only gone a few meters when he heard his wife calling him again.

    "I'm all right now, and I shall not want the doctor." she said softly.

    Hearing this, he started running as 7 as he could towards the doctor's. When he arrived there, he knocked at the door loudly enough to 8 everyone around.

    The doctor put his sleepy head out of the bedroom window and said, "Er? Who's there?"

    "Oh, Doctor." Peter called up to him, "I've very good news for you. My wife 9 ill with a terrible stomachache. I was on my way to bring you to her, but she called me back to say the trouble had suddenly 10 her. So you need not come. Go back to bed now, and sleep well!"
