关于水的作文题目开头【一】
古人语：“地力之生物有大数，人力这成物有大限，取之有度，用之有节，则常足，取之无度，用之不节，则常不足。”这句话的意思是：自然界所生长的万物（资源）是有限的，由人来加工制成的物品资源也有限。而取时有限度，用时节约，则常常能满足人类的需求。如果相反，取时无限度，用时又浪费，那么球上公有的资源就会很快消失。

as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth＇s surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
关于水的作文题目开头【三】
扔垃圾，排废水，排废气等等的恶劣行为，使我们离不开的水变得浑浊，变得肮脏。不过，人类的恶性远不止是污染水，还有浪费水。为了避免人们不认罪，我把当时的录像都拿来了，让大家看看——水在哭泣。
大家都看过一个广告吧。一个小男孩生活在干旱地区，他提着水桶，来到水龙头前希望水会流出来。而另一边的城里人因刷牙时没关水龙头而让水哗哗白流。后来，城里人关掉水龙头，另一边就有水了。其实在我们身边也有这样的事，有些人洗好手后忘关水龙头了。水就抽噎着说：“你们人类往我们家里扔垃圾也就算了，还……还浪费我。你要知道，有些地方的人连干净的水都喝不上。你节约一滴水，就能救一个人。节约一盆水，就能救一千个人……”
第二次，不是忘关水龙头这种“小事”了。一辆车正在倒车，一不小心撞上了旁边的消防栓“大哥”，不仅身体被撞得扭扭歪歪，他的水宝宝们也不能幸免于难。水又哭泣着说道：“你说你们，上次没关水龙头也就算了，这回你们得寸进尺把消防栓也给撞破了。你看看，这不就成了一个喷泉了吗。哎，我的同胞们，就这样被你们白白给浪费了。我看呐，那些在‘喷泉’下冲凉的人都比你们强，至少他们懂得怎样充分运用水资源。可恶的人类，如果你们失去了水，那后悔也来不及了。”
你可别以为就这两桩事，人类的恶行还多着呢。如果，我们在知错不改，那就来不及了。我们要从身边做起，节约用水，合理用水，不浪费水，不污染水。最后，我要告诉大家——水在哭泣。
