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.

port life. without water, human beings, animals and plants cannot exist at all.
首先,水对生命是非常重要的。众所周知,水是维持生命所必需的。没有水,人类,动物和植物都不复存在。 second, water is also significant for producing. for one thing, industrial production needs a lot of water, such as using water to generate electricity. for another, agricultural production is also in need of water, especially in irrigation.
Some people think studengts need not do any housework。They think the only thing students need do is to study well。 I don’t think so。 It is good for students to do some housework for three reason。
Firstly,to do some housework can make you independent。You can’t depend on others all your life。So,you should learn to do some housework now。
Secondly, to do some housework can keep you healthy and strong ,some hard housework can be regarded as a kind of physical exercise。
Finally, to do some housework can share your parents’ work 。They must be happy if you say” Have a rest ,and I will do the housework”
So I think it is good for students to do some housework。
一进入景区。景色太优美了。路的两旁是翠绿的柳树,有些游客坐在柳树下的椅子上休息。远处,有一条清澈见底的湖泊。湖中还有几只水鸭子在游玩。它们时而拍打着翅膀飞快地在水面上滑翔,时而活泼地在水中游泳。我们怀着愉快的心情边走边看,不知不觉地来到了太极洞口。
站在洞口,一阵寒气扑面而来。我更加迫不及待想去洞中探索一下。我拿着自备的'手电筒进洞了。虽然里面很阴暗,地上也很潮湿,但是不远处五颜六色的光吸引了我。我赶忙往前跑,看到左右有两个牌子。左边写的是“旱洞”,右边写的是“水洞”。我们决定先游旱洞。
进入旱洞,看到旱洞里有很多石像,如“太上老君”、“千年灵芝”、“莲花宝座”、“灵宵双塔”等等。这些石像惟妙惟肖,特别是“千年灵芝”,简直像真的一样,我忍不住摸了一下,感觉硬硬的,才确信那是石头的。走着走着,我看见路旁边有个石头,上面有水滴下来,旁边的牌子上写着“水滴石穿”。我一看,果然石头上有个洞,原来这就是“水滴石穿”哦。妈妈告诉我,“水滴石穿”告诉我们有志者事竟成的道理。就像爱迪生,他失败了好多次,但是他不放弃,最终发明了电灯。
参观完旱洞,我们来到了水洞。我们乘上了船,沿途观赏着洞中千奇百怪的钟乳石,心情无比舒畅。不知不觉我们上岸了。上了岸,经过一段平路,前面出现了陡峭的楼梯,一眼望不到头。旁边的牌子上写着“高抬贵步”。看来这是出洞的必经之路了。我一股作气爬了几十级台阶,抬头看看怎么还不到啊。正当我气馁的时候,突然想到了刚才看到的“水滴石穿”,顿时又有了信心。我加快脚步继续向前进。终于看到远处有一丝亮光了,感觉气温也越来越高,我想胜利就在眼前了,高兴地哼起了歌。
出了洞,我们选择步行下了山。我站在山下,看着远处的太极洞出口,心想:今天我不仅看到了美丽的景色,还学到了“水滴石穿”的道理。以后碰到困难,我一定会用它来激励自己。
