I live in a very old town which is surrounding by beautiful woods. It is a famous beauty spot. In Sundays, hundreds of people come from the city to see our town and to walk through the woods. Visitors have asked to keep the woods clean and tidy. Litter baskets have been placed under the trees, and people still throw their rubbish everywhere. Last Wednesday, I go for a walk in the woods. That I saw made me very sad. I counted seven old cars and three old refrigerators. The  litter basket were empty and the ground was covered with pieces of paper, cigarette ends, old tyres, empty bottles or rusty tins. Among the rubbish, I found a sign which was said, “Anyone who leave litter in these woods will be punished!”
