At midnight (半夜) Mr. King coughed again. He got up and took some medicine. Before he lay down again, he smoked. And he couldn't go to sleep any longer. He found the medicine book and began to read it. He was afraid he had lung cancer(肺癌). He seemed to see death was waiting for him. Tears (眼泪)ran down his face. He didn’t see his wife was standing by him.
“What’s wrong with you, dear?”asked the woman.
“Nothing,” the old man answered and covered his face with his hands. The old woman opened the book and understood at once. She said, “You must stop smoking right now. ”
“I began to smoke when I was nine, you know. How can I do that?”
“But I think health is more important. ”
Mr. King coughed again and his wife said, “Go to see a doctor tomorrow. He will be able to help you, I think. ”
The doctor told Mr. King to have an X-ray examination（X光检查）of his lungs(肺). And then he looked at the X-ray carefully for a long time.
“Tell me the truth, doctor. ” said Mr. King, “Do you see any shadows (阴影) in my lungs?”
“No, I don’t see anything. ”
“Yes?” the old man said happily. “Really?”
“Yes. Your lungs are turning black. How can I see any shadows?”
