listen to the tape then answer this question.
what was so funny about the words on the sign ?
i live in a very old town which is surrounted by the woods.
it is famous  beauty spot.
on sundays, hundreds of people come from the city to see our town and to walk  throught the woods.
visitors have been asked to keep the woods clean and tidy.
litter baskets have been placed under the trees,but people still throw thire rubbish everywhere.
last wednerday,i went for walk in the woods .
what i saw made me very sad.
i counted seven old cars and three old refrigerators.
the litter baskets were empty  and the groud was covered with pieces of paper ,cigarette ends, old tyres,empty bottles and rusty  
tins.
amog the rubbish,i found a sign which said,"anyone who leaves litter in these woods will be prosecutes.
