In the middle of the night, Peter’s wife suddenly fell ill. She couldn’t help crying, “Oh, my stomach (胃)! Get the  16  !”
Peter, awaking from a deep sleep, thought his wife was only having a 17 dream.
“Stop that noise.” he said to her. He turned over and tried to go to  18 again, but his wife still cried out, “Oh, help! Help! I’m sure I’m  19 !”
Peter got out of bed and started  20 , but he could not find him any clothes.
“Where is my shirt?” he asked. His wife was  21 ill to tell him, and she could only cry, “Oh, my  22 stomach!”
As soon as he had put his clothes  23 , he said, “Now, my dear, are you quite  24 that you need the doctor? Surely you can wait  25 morning, can’t you?”
“No, I can’t. Go, go, go.” his wife shouted,“  26 you will find me dead  27 the morning.”
So Peter went out into the dark street. He had only gone a few meters  28 he heard his wife calling him again.
“I’m  29 again now, and I shall not want the doctor.” she said softly.
Hearing this, he started running as  30 as he could towards the doctor’s. When he arrived there, he knocked at the door loudly enough to wake  31 around.
The doctor put his sleepy head out of the bedroom window and said, “Er? Who’s there?”
“Oh, Doctor.”Peter said to him, “I’ve very  32 news for you. My wife  33 ill with a terrible stomachache (胃疼). I was on my way to bring you to her, but she called me back to say the trouble had suddenly  34 her. So you need not come. Go back to   35 now,and sleep well!”
