1．水对我们的日常生活非常重要，没有水一切生物都无法生存

【答案】

As we know, water is very useful and important in our daily life．Without water, all living things can’t exist．Water can be used to make electricity and irrigate farmland．Plenty of water is also needed in industry and transportation．So we must save every drop of water．I think there are many measures we can take to save water．For example, we can use the water with which we have washed clothes and vegetables to flush toilets．We can try our best to wash clothes by hand instead of washing machine, for using a washing machine means wasting 3 times as much water as by hand．While washing clothes, faces and brushing teeth, we mustn’t have the water running all the time．
