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.
今天哥哥去打乒乓球,我也跟了去。我们商量好了,哥哥和陈明远是比赛双方,我是裁判,“滴滴”我神气地吹响了开始的哨声,哥哥和陈明远开始了难分难解的厮***,别看他们年纪小,打起乒乓球来却一点不比运动员逊色,只见他俩 你来我往,终于陈明远抵挡不住哥哥的猛烈攻势先丢了一分。
陈明远不甘示弱,用衣角擦擦球又慎重地对着球拍吹了口气,好像他的那口气能给他带来好运一样,我忍不住笑了起来,他生气地说:“有什么好笑的?没看电视上运动员都是这样做的吗?”看着他 那认真的模样,我笑得直不起腰。
比赛又开始了,他们都打得很谨慎难分胜负,可真是难为了我这个裁判,老实说对乒乓球我基本上是个门外汉,一个球掉在地上,哥哥说他得分,陈明远说哥哥犯规了应该他得分,他们争得面红耳赤 我这个裁判却插不上嘴,幸好这时陈明远的妈妈喊他回家吃饭,否则我真不知道怎么收场,看来我以后要多研究研究乒乓球,事事留心皆学问呀。
其中一个乒乓球拍说:“我的本领最大,没有我,你怎么弹来弹去。”另一个球拍说:“就你?算了吧,我才最厉害,没有我你怎么接球。”乒乓球按捺不住了,说:“没有我,你们打什么球呀。两个球拍齐声说:“就你那小样,还说你最厉害,哈哈哈哈…”乒乓球说:“你们欺负人,总有一天,你们会知道我的厉害的,哼。”"我们就欺负人,怎样。"乒乓球拍傲慢的说。“我真的生气了,我真的生气啦。”乒乓球愤怒的冲向球拍,“呵,终于生气啦,啊?球拍说”呀,。”乒乓球给球拍一个大拳头。“好你个臭小子,吃熊心豹子胆,是不,找抽啊。"球拍说“对啊,我就是吃了熊心豹子胆了,怎么样。”砰的一声,乒乓球吃了个无影拳。“敢打我,找死啊。”乒乓球说“对啊,我就找死。”球拍说,“砰”球拍也吃了个大拳头,“轰轰砰砰”糟糕他们打起来了。
第二天清晨,球拍和乒乓球的主人——伍潇潇起来了,看到球拍和乒乓球破破烂烂的,就把他们扔了,买了新球拍和乒乓球。这时候,他们才后悔不已,可惜他们只能在垃圾堆里度过余生了。
