msh10282020-04-21👍734 water is very important and we can’t live without water.nowadays ,there is less and less water exsist in the world and people waste water terribly ,what’s more the water is seriously polluted now.the problem we face now is very difficult ,everyone need to do something to help save the water,protecting the water resouces is the most important thing we should do now . 或 as we all know, water is so important that we can’t live without water .just let me show you an example. long ago , there were two famous cities:one was los santos, the other was san fierro. it was reported that beside them, there was a strange lake.the lake was not large at all,but if you put any vehicle into it ,immmediately it would disappear.so it was named as “ghost lake”. a citizen called carl johnson didn’t believe it at all.one day, he stole a car and drove to the lake.it was late at night.the wind blew hard,with strange noise going around from darkness. many high trees were laid down in the way.eventually,cj arrived at the lake.he tried to push the car into water,it did disappear! he didn’t believe in ghosts,so he just dived into water.oh,so many cars! he at once realized that it was the dirty water that made us feel puzzled. so,how serious the water pollution is! it not only makes the world bad, but even makes human puzzled! hehe……
