參考範文
jinyun mountain is a famous place of interest.every day a lot of tourists come here to enjoy its beauty. but a few years ago,some of them paid no attention to protecting the environment.they threw their rubbish,such as plastic bags,fruit skins and waste paper on the ground.sometimes they broke trees,picked flowers and killed birds. some even made fires in the woods to cook food.how dangerous it was.luckily,great changes have taken place here.tourists are used to putting their rubbish into dustbins,and they are doing their best to protect the birds and plants as well.they bring their own meals instead of cooking to prevent starting a forest fire in the mountains.all these changes make us very happy.
