Possible version:
How to Save Water
Water is very important in our life. We drink it every day and use it to cook and wash things. We cannot live without water. But in our daily life, we sometimes forget to turn off the tap. And we take long shower. We even throw rubbish into the river.
Do you know how to save water There are several ways to save water. Firstly, take shorter showers and don’t leave the tap running when we don’t need to use water. Secondly, try to reuse water. It’s the most important way for us to save water. At last, we should not pollute water so that we will have fresh water for years and years. If we do not save water, the last drop of water will be a teardrop. To protect water is to protect our life.
