我们应该怎么节水 英语作文
答案
Some people think there's much water on the earth.In fact,there is only a little water for us to use now.If we don't save it,it will surely be used out some day.
Then what should we do?
First,when we finish washing the clothes,we can use the water to clean the floor.Second,if we see the dripping tap,we ought to fix the tap as soon as possible.Third,we can have a shower instead of a bath because having a bath can waste a lot of water.
In these ways,we can save not only huge amounts of water but also ourselves!
Water is very important in our life. We drink it every day and use it to cook and wash things. We can not live without water. But how can we 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 willl 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.
