One summer evening, I was playing and some childs by a river. We saw a lot of frogs(青蛙) in the water. One of us said, “Let’s to see who can catch most frogs.” Then we began. After while we caught a lot. We are having a good time when a farmer shouted at us. “Don’t caught frogs!” Then he told us how importance they are to farming. They eat a lot of bad insects(害虫)every year. Caught frogs must be stopped. After hear that, we felt very sorry.
