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.
水——我们的朋友 平达曾说过:“自然界的一切事物中,唯有水最珍贵。”是啊,水是我们的朋友,没有了水,就没有了我们。让我们一起与水做个好朋友吧! 水看见人们不节约用水,伤心地说:我对人类的所作所为感到不满,我为人类做了那么多的贡献,可人类总是滥用我。这样既会导致水源的'流失,又会严重影响生态环境。 在生活中,处处都要用到水。洗菜要用水,洗车要用水,洗澡要用水??,这往往会浪费很多水。其实,请把水龙头开小一点,把废水再次利用,这样我们就能与水做好朋友了。比如:洗菜水可以浇花;洗澡水可以冲马桶??这样,不仅能节约用水,还对别的事物有好处呢! 如果水能这
样一滴一滴的节约起来,虽然不是太多,但是全世界人民都这样做,怎么会没有水呢? 人们可知道,世界上有许多地方水都很少,有些人,因为喝不上水,而死去,他们说:“请他们喝酒,不如请他们喝水。”下雨天,曾是他们最快乐的日子,他们可以用雨水洗澡,还能接水,以后用。他们把水当做奇珍异宝, 每次喝水都要去很远的井里去挑,那井里的水比黄河水还浑浊,比海水还难喝。由此可见,他们是多么爱水啊!如果我们能节约用水,他们的生
活难道会这样吗? 不节约用水,不但会导致水源的流失,还会影响生态环境。 有些工厂既不节约用水,还排放污水放到河流中,这样,水不仅流失了,还会影响生态环境。
在我8岁那年的国庆节,妈妈高兴的对我讲:明天姨妈和哥哥一起跟我们去公园坐船玩耍。我一听这个消息,一蹦三尺高,这可是我老早就梦想的事情了,连晚上做梦都梦到坐船的经历呢!
第二天,我早早就起床了,全副武装了一番。哈哈!太阳婆婆也好像知道我今天有高兴的事,也早早的升起来,温柔的看着我。一路上我蹦蹦跳跳的来到了湖边,挑了一艘蓝色的船,急不可待的上到船上。我问妈妈:船会不会急拐弯,会把我们掉到水里吗?妈妈讲:不会的',不过你要扶好栏杆。我的心里好像踹了几只活蹦乱跳的小兔一样,难以平静。船开了,开得越来越快,这时,我看见天像被蓝墨水染了一样,白云被风一吹,有时像可爱的小白兔,小绵羊,有时像小鸟裹着白色的衣服在蓝天中穿行。我又看见了那些高大挺拔的大树像士兵一样一个个在两侧站着,还看见那些小花、小草倒映在湖面上,像一幅栩栩如生的画。我被这迷人的景像迷住了,哥哥用手推醒了我。感觉非常凉爽,我叫哥哥站起来也感受感受。妈妈看见我们这样,突然把方向盘一打,给我们来了一个转弯,哎呀!把我们都吓得腿都软了,水花也溅到我们的衣服上,妈妈和姨妈都偷偷的笑了,我们也不禁哈哈大笑了起l来·······时间真快,20分钟过去了,我们回到起初坐船的地方。
这次,虽然是短短的20分钟,却让我感受到了蓝天、白云、大地原来是这么的美。我好喜欢坐船,下次如有机会我还要到大海上去坐船,肯定感受又是不一样的。
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。
