      Mr Backer is a kind-hearted man. Once he gave some food to a poor woman. Mr White, the boss of the

restaurant, found it and became angry. He often gave the leftovers (剩饭菜) to some poor workers. Mr

Backers lost his work for it. It was difficult for him to find work in the small country though (虽然) he was

an able cook.. The war made all stop. Children couldn't go to school, most shops were closed, even some

was an autumn night. Mr Backer hadn't any food to eat and went to bed, but he couldn't fall asleep. Suddenly

it carefully. At last the man brought a few old clothes out of a broken paper box and took them away. He got

up quickly and followed him gently (文雅地), with his quilt on his back. The man didn't find him and went into

a small and wet house. Mr Backer also went in and saw there was nothing in the room. The thief (贼) saw him
