Water is very important to us, without that there would be no life. We couldn’t live if we didn’t have water. Therefore, some people don’t turn the tap off at once after using it. Some people don’t realize they wash them in the shower too long. Some even throw away bottles full in water. As middle school students, we should make great efforts to save water.
