is being done to the ancient forests of Britain. Many
visitors to the forests use stones to cut their names
into the trees—some of which are hundreds of years
old. Although there are plenty of rubbish bins, people
still throw rubbish into the stream and this causes
plants and fish to die. A local conservation group is
making a huge effort to help. Students and even
retired(已退休的) people from the local villages have
all got involved in cleaning up the forests, and they
have already achieved good results. But we expect
the tourists to play their part in keeping our forests
clean, too!Reading 1. What are people worried about?2. What do people do to damage the forest?3. How do people do to solve the problems?The damage that is being done to the forestsHave all got involved in cleaning up the forests--Use stones to cut their names into the trees.
