     Mr. Green was clever three years ago. And few men could trouble him. But one day he was hit down by a

car and his head got badly hurt. And now he often forgets something and thinks in a different way from ours.  

     One morning, Mr. Green woke up early. He put on his coat and began to walk in the street while people were

sleeping. He wanted to buy newspapers but the post office was still closed. He had to go back and go to bed

again. Before he took off his clothes,someone knocked at the door. He got up and opened it. Two hunters (猎人)

came in. They looked at him carefully and then said, "We saw a dead man just now. We thought it was you."

     "Really?" Mr. Green said in surprise. "Where?"

     "In the forest."

     "It's impossible!" said Mr. Green. "I didn't go there at all this morning."

     "But he died last night."

     "I haven't been there for nearly a week."

     "But he looks like you."

     "What clothes does he wear, then?"

     "A blue coat like yours and brown pants."

     "And what color are his socks?"

     "Black."

     Mr. Green became happy. He showed his socks to them and said, "Look! Mine are white."
