The oceans cover two thirds of Earth ,but ocean water is .That is to say ,most of the water in the world is not
90% of all the water on Earth that human beings can drink right now is .It is very easy to pollute the groundwater.For example ,4.5 litres of paint or about 1litre of motor oil can seep into the earth and pollute 1,125,000 litres of water
A leak that fills up a coffee cup in 10 minutes will waste over 13,500 litres of water in a year.How much water is that You should have to drink 65 glasses of water every day for a year to get that much water
If you leave the water running you brush your teeth ,you might waste 22.5 litres of water each time ---enough to wash a whole car
it or not ,the water we flush down our toilets starts as fresh water Each time you flush ,you toilet uses about 18 to 31.5 litres of water .But it does not have to
A shower usually at least 5 minutes.So every day ,you might use 50 litres of water taking one shower.a year ,that is almost 15,000 litres for your shower!

海洋覆盖了整个地球面积的三分之二,但是海水是（咸的）...也就是说,绝大部分的地球水是不能（直接饮用的）.
目前人们的饮用水有90%是来自于（地下水?）...但是,地下水是极易遭到污染的.比方说,4.5升涂料或1升机油可以渗入地下并污染1125000升水.
一个10分钟能漏一咖啡杯水的龙头,在一年里,能漏13500升水或者更多.那将是多少水啊?你得每天喝65杯水,连续喝一年才能喝完那么多水.
每次开着水龙头刷牙的时候,你就浪费了22.5升水.这么多水足够洗一次车了～
（信不信由你）,但是每次冲马桶,我们就冲走了18～31.5升干净的饮用水.这种浪费是完全可以避免的
假设你每天冲澡5分钟,那么你每次就要用50升的水.按这样计算,你一年用于洗澡的水就有15000升之多

啊！这…………这……这也是我的作业啊
