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.

最后,做一些家务可以分享您的父母的工作。他们必须高兴,如果你说“休息一下,我会做家务”因此,我认为这是为学生好做一些家务。
巍巍呼高山,汤汤乎流水。飞涧旁这段以诚相待,曲论相和的一瞬定格为千古佳话。知音难求,伯牙奏琴为子期,摔琴亦为子期。这情意如何不令人感动。而今,披肝沥胆的知音再也难觅。只缘人们拥有的纯洁太少。没有水的纯净,没有透明敞开的胸怀,着世间就无真诚可言。何不收其虚伪,展示真诚。
看着这透明如水晶的水,我们那颗被世俗之尘掩埋得太久的心,怎能没有冲见天日呼吸真诚的冲动。拥抱纯真,拥抱真诚,去成就一段马克思恩格斯般高尚的友谊,去结交一位誓友,莫逆,忘年,只要心相知,手相牵,意相同。
水教人真诚,正如叶尖那滴雨露,透明纯洁,折射出太阳的光芒。
天下之柔莫过于水。昼夜不舍的滴坠去赋予水无穷的力量。因渺小而被忽视,因忽视而暗中积攒着力量,直到将万年磐石一点点磨蚀,在世人惊叹的注目中有了穿石的壮举。
明白了持之以恒,竺可桢数十年如一日,观察记录天气情况,终成举世著名的气象学家,懂得了锲而不舍,贝多芬在静寂的世界中,用心灵演奏了命运交响曲的豪壮,有了水刚柔相济的力量,这世上多了几份执着,几份坚持。
水教人执着,正如那穿石得滴水,下坠,下坠,最终拥有成功的欢悦。
水,这就是水,水以其博大,纯净,力量感动着我,而我亦将用博大,纯净和力量去书写自己的人生,我不敢奢求拥有一段辉煌的人生,我只企盼今生无悔。
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。
昨天下午刚刚下课,我便疾奔向学校充卡处。原来跟我一样需要充卡的人还真不少,熙熙攘攘的。看见密密麻麻的人头,我禁不住有些焦急,但还是沉下气来站到队伍的最后头。说是队伍,其实根本就不算,说来倒更像一个大大的肉团;看见大家都互相推挤着,为了不使自己被撞伤挤坏,我宁愿站在最后头。
等了很久,迟迟轮不到我被服务。往往一个人挤到了窗口,认识他的人就把卡递了过来,于是这位同学便一连充五六张,充完后便会满脸骄傲的挤出去。无奈,这就是能耐?!排了半个多小时,终于捱到了窗口,刚想把卡递进去,一个看起来文静瘦弱的女生猛的给了我一下,瞬间,一个趔趄让我滑出原坐标,手立刻被锋利的护栏划了个口子。步子还没有站定,一位仁兄又发话了:“不排队,别在这里站着!”没心情跟他理论,独自捂着滴血的手走出人群,于是,饿了一顿。
其实,本来很简单的事,只要排好队,一个人只须几分钟便轻松搞定,可是同学们为何偏要这样去比拼力气,难道觉得这样更有意思?
计划经济时代物质贫瘠给心灵上造成的恐慌不安,和由这惶恐而致的“不素质”,在物质大为丰富了的今天,本应随着丰裕悄悄淡去,但是,却是如影随形的跟进,而且没有削弱之势。君不见,大学售菜窗口即使只有两个人,也会发生一点小拥挤;公交车来了,即使人不多,大家仍然一如既往的争先恐后;还有自助餐厅里,随处可见的人走饭菜盈桌现象。
这些疾病,除了我们的爷爷奶奶爸爸妈妈不小心本能的传染给我们之外,难道没有我们自己的责任吗?
“为中华之崛起读书”“天下兴亡匹夫有责”“先下之忧而忧”难道永远只能写进我们的作文本里,卷上,而不会带进我们一日三餐和生活的坐卧行止里?何时才能把这些优秀的思想化为我们的行动,我们的素养,就真正提高上来了。
多么希望,我们的同龄人,在课堂上学习了范仲淹欧阳修苏轼李白白居易之后,能把这种对古人敬仰之情愫迁移到课下的餐厅、甬道、宿舍乃至厕所;多么希望,我们的家长,在孩子在场的时候,能够略微忍耐一下,把最好的座位让给刚上车的老人,把最便利的服务优先让老弱病残者享用,把怯懦的目光收起,坦然面对假恶丑;多么希望,我们的社会,在旁观者冷眼作壁上观之后动用舆论的力量声讨以震慑人性的冷漠,在鳏寡孤独者受难之时能够义无反顾的动用强大的福利链条让他们皆有所养!
素质不是一句口号,喊喊就可以上去的。任重道远。我辈若能死而后已,相信不久的将来,全民素质会提高到让外国人刮目相看的高度!
水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。
