求大神做一道高中英语改错题
一共有十处错误.Looking at the map of the world,and you can see that three quarter of the earth is covered by water.Therefore,we are short of water,it sounds strange to you.But it is true.You see,97% of the total water in the world are sea water,which is so salt that man can't drink it.So only 3% of the water can be drunk or used for man.And the drinkable water comes from rivers,lakes and underground.Man even can't use them completely,because the water contains icebergs and glaciers.All what is the worst is that water in some parts has been polluted or is being polluted .How can we drink?So something must be done to prevent water from being polluted.
