For me, a school trip to the wastewater plant is the most unforgettable day. I used to waste water a lot. When I washed hands, I always let the water run for a long time. I never thought about how hard it was to get clean water. Last Friday, our teacher took us to visit a wastewater plant. The workers there showed us their daily work. They used big machines to clean dirty water. There were more than five steps to make the water clean and safe again. It took workers lots of time and energy every day. After visiting the plant, I completely changed my idea. I realized clean water is not easy to get. It is a precious resource for all people. Now I never waste water in my daily life. I also tell my classmates to save water. This special day teaches me a meaningful lesson: never waste any natural resource, and always respect workers’ hard work. 1.
