求翻译：水，生命之源，没有水我们怎样生活下去？现在的水，受到了大量的污染，不再像以前那样清澈，不再像以前那样美丽。外婆说过，小时候，家门前的小河流，清澈见底，好像永远也取之不尽、用之不竭，水底下的鹅卵石密密麻麻的排在一起，河里的小鱼，轻松自在的游来游去，村民们口渴了，就可以从这取水喝，用不着煮过或过滤，方便又干净！可是，现在，早已看不见这样的场景，还动不动就从新闻报纸上看见：那里要动工清理水源，那里要保护水源……现在世界上的人都有责任，水，受到了污染，能使用的水量也越来越少，世界受到了迫害，所以我们要保护世界，拯救世界！是什么意思？

Water, source of life, how we live without water? Now water contaminated by a number, no longer as clear as before, no longer as beautiful as before. The grandmother said, as a child, in front of the small river, the Crystal clarityof seems forever is also inexhaustible and always available, cobblestone beneath dense rows with water, small fish in a river, comfortable swim to swim, villagers are thirsty, you can drink water from this without being boiled or filtered, convenient and clean! However, now, has long been seen such a scene, also tempers out of newspaper, see: where to start cleaning up water, to protect water sources there sth Now is the responsibility of everyone in the world, water, pollution, the water is also used less and less, had suffered in the world, so we have to protect the world, save the world!
