Last summer holiday， I paid a visit for① my friend who lived near the Songjin River. When walking across a bridge， I saw a group of students sitting by the river and drawing pictures. The river was clean with small flowers and grass on all② sides. The air was fresh and many people took walks， talking happily under the trees.
　　But it used to be a black river and there was a lot of rubbish floating on the water， which gave off a terrible smell. By the end of 2010， the river had been clean and there had been a lot of living things in it. But with the development of industry， the river became dirty. At that time， people there wished the river could be clean again.
　　Fortunately， in the past two years， the government has paid much attention to the project of cleaning the river and spent a lot of money in③ it. Through painstaking effort， the river is now clean again. How nice the clean river is！
　　We’ll try our best to keep it cleaning④ for ever. We hope that everyone will protect water and keep water clean because we only have one earth.
