XX四年级节约水资源作文 【篇一】 我们国家的水资源其实不丰富，假如再不注意节约用水，我们将面临严重的水荒。这件事让所有人都很担忧，因为谁随时都有可能发生，所以就让我们一起来爱护水吧，不要让水资源大量的消耗。下面我就来讲讲我人家人浪费水资源的事情吧。 其中我们家就是特别浪费水，每次爸爸洗完手总是不关水龙头，让水一直留在水槽里，有时妈妈洗完脸也把水直接倒在水槽里，有时奶奶去垃圾也会把垃圾扔到河里…… 我决定给我们家做一个爱护水资源的会议，爸爸洗完手之后应把水龙头关好，不要浪费水，不然那些贫困区的小朋友就用不到水了。 妈妈洗完脸之后应该把用脏的水再次利用了才到，不然的话，每个人都像妈妈一样，那我们国家就严重缺水了。奶奶应该把垃圾扔到垃圾桶里，不应该扔到水里，假如这样污染了河水，河水就会发臭，那里就不是优美的景区了。 听了我的介绍，请大家都要做好爱护水资源的好人民，不要把水资源浪费在自己的生活中，更不要把自己身边的水资源化作一摊垃圾堆，这样就更容易使我们国家变成水荒了。 【篇二】 水是生命的源泉！水的用处可大了，刷牙、洗脸需要水，洗衣、做饭需要 水，养花、种树需要水，灌溉农田需要水?…总之，水给我们的生活带来了不少 的方便。 世界上的淡水资源是有限的。我们乐清就是个缺水的地方，假如长时间不下雨，这里就会干旱，生活用水也难以保证。有一次，我们家停水了。早晨，我拿起水杯，打开水龙头，咦？怎么没水了？我奇异了。我去问妈妈，才知道停水了。停水了，牙当然不能刷了。我一个上午都没喝水，到了中午，我渴得受不了了，妈妈叫我去买两瓶矿泉水。我带了两块钱下楼，没想到矿泉水要一 块五一瓶。我又得回家再拿一块钱下楼，终于买了两瓶矿泉水回家，唉，可真费

保护水资源的300字作文 引导语：水资源的稀缺是一种水资源匮乏的现象,因为地球上水的总量一定,饮用淡水的总量则更少,随着利用和不合理浪费越来越剧烈,水资源缺乏问题日益明显。下面是小编为你带来的保护水资源的300字作文，希望对你有所帮助。 【第1篇】星期六，我们小记者去自来水厂参观，保护水资源作文300字。 自来水厂的陈阿姨接待了我们，她开始给我们讲解起来。漳河水是怎么流进千家万户的呢？这也是我很想问的问题。陈阿姨带我们看漳河。哇，这么大！一眼望不到边呢！河水看起来很清，陈阿姨说，漳河是我们的母亲河，它是漳河原水抽至取水泵房，加氯到过滤池……最后才抵达千家万户的。听着陈阿姨的讲解，想不到我们现在的饮用水竟是这样来的，我不禁想赞一个："神奇的漳河水，了不起！"接着我们跟随工作人员到提水的地方。"好高！这些工作人员是怎样上去的呢？" 我们问陈阿姨。陈阿姨告诉我们："那边有个弯弯曲曲的楼梯，顺着下就行了。"我往下一看，水管弯弯的，有的大，有的小，看起来可真有意思。 不知不觉，这一次的参观就结束了。通过参观，我想对着漳河呐喊："漳河，真了不起！" 【第2篇】最近，我国西南地区发生了严重的旱灾，有许许多多人没有饮用水，有些地方从去年七月份开始就没有下雨了。我最 ————来源网络搜集整理，仅供个人学习查参考
近从报纸和电视上了解到，云南、贵州、重庆、四川等地区旱灾情况非常严重，原本宽大的河流因旱灾变成了浅浅的溪流，有许多人还因为寻找水源而死去。 为什么我国会发生百年不遇的大旱灾呢？主要是因为我们人类制造出许多二氧化碳。所以，我们以后可以少坐汽车，多走路，这样可以尽量减少排放二氧化碳，300字作文大全《保护水资源作文300字》。我们还要节约用水，不要浪费水。要记得关好水龙头，洗澡尽量不要洗太长时间，这样做很浪费水。我们平常还可以把洗手、洗水果蔬菜等用完之后还比较干净的水收集起来，还可以再加利用。 水是生命之源，我们要节约用水，保护水资源。 【第3篇】水，和人类息息相关！ 在地球上，有70%--75%的海洋面积，可是只有三分之一的淡水。在我国，600多个城市一半是缺水的，就说云南省吧，那里已经干旱了三年，小河断流、水库干涸，真是很不好啊！ 在小河里，人们在河里杀鱼，那鱼血把清澈见底的河水变得浅红浅红的（一般叠词表示程度深。深红深红比较多用，浅红浅红似乎不恰当。人们在河里杀鱼，那鱼血在河里荡漾开去，把清澈的河水染成了浅红色的一片）。在家里，明明打了一大盆水，只洗了洗手就把它给倒了，真是太浪费了。在卫生间里，已经冲得很干净的马桶再去冲一冲，这清清的水又流向下水道。 在身边，也有人在一次又一次地利用一盆水。奶奶每次把洗脸水用来洗拖把；傍晚的时候，她又用淘米水来洗菜，再去浇浇她自己种
小学四年级英语作文优秀范文 小学四年级英语作文 ：城市绿化 Make Our Cities Greener Directions : For this part, you are allowed 30 minutes to write a composition on the title: Make Our Cities Greener. Your composition should be based on the following outline: 1．城市绿化的现状； 2．绿化的好处(如：清新空气，美化城市，改善气候……等等)； 3．怎样才能实现绿化。 Your composition should be no less than 100 words. Write this composition on the Composition Sheet. Remember to write it clearly. Make Our Cities Greener （约 200 字） Many things have been done and great progress has been made in the greenization of our cities in recent years. Many trees have been planted and much care has been taken of the planted trees. But, in spite of all this, greenization in the cities in China is far from satisfactory compared with cities in other countries in the world. For example, the green space for every people in Shanghai is only 2 square meters while that of the people in London exceeds 20 square meters. We can benefit much from the greenization of our cities. First, trees absorb carbon dioxide which is harmful, but produce oxygen which is essential to human beings. Secondly, with trees all around, our cities will look more beautiful. Thirdly, trees can improve the climate of the cities, making it neither too hot in summer nor too cold in winter. Since we can get so much benefit from making our cities greener, we should spare no effort to do so. We should plant even more trees and take even better care of them while they are growing. Besides, we should not cut down trees any more. In a word, we should do everything to add to the greenization of our cities. 小学四年级英语作文：我房前的树 The Tree in Front of My House 我房前的树

保护水资源的作文300字 导读：篇一：保护水资源 水是人生生存不可缺少的条件之一，没有水，也就没有生命的存在，所以我们要保护水资源。 据统计地球表面的水储量大约有140亿亿立方米，但淡水资源只有3。5亿亿立方米。这些有的水资源只有0。34是人类可以饮用，由于分布不平衡，生活浪费，全世界百分之六十的地区供水不足，严重缺乏用水，情况严峻。 再加上各种有害物质，污染水，人饮用后，可能使人慢性中毒，或者生疾病，严重的可能会死亡。 一些工厂。医院不把有害的水排放到该排放的地方去，而是随便的把水排放到河流。江湖或海洋。水中鱼儿。虾蟹喝了这些水会死亡，而这些死鱼死虾死蟹讲送入人类口中，这些死的水生物带毒，可能会讲毒留在人类的身体中。 我们要保护水资源，不要让世界的最后的一滴水是我们的眼泪。 篇二：保护水资源 水，是生命之源，任何物质都不可替代。没有水就没有生命，更谈不上什么文明和发展。然而，由于世界人口的剧增、人类的过度索取和浪费，以及工业污染等原因，世界淡水资源越来越匮乏，人类正面临着严重的水危机。 水是那样的普通，普通得让人须臾不可缺少而又随时可以忘记。
人只是在饿的时候想到吃饭，渴的时候想到喝水，而对于粮食和水本身，可以说关心得很少甚至从未关心过。至今，绝大多数人的心目中，水仍然是取之不尽用之不竭的，到处都是对水资源的过量开采、挥霍浪费以及粗暴的践踏与污染。 水资源是人类的共同财富，保护水资源，必须提高人们对水资源的认识。国家应制定出相应的节水法规，大家应自觉养成节约用水的良好习惯。我们应该从身边小事做起，在生活中节约用水，与浪费水资源、破坏水资源的行为做斗争。 如果人类继续破坏和浪费水资源，那么人类看到的最后一滴水，将是自己的眼泪！ 篇三：保护水资源作文 今天下午，我、妈妈和姐姐去郊外踏青。 我们正坐在草地上，突然，姐姐尖叫一声，把我们都吸引过去了，我们看见一条被污染的小河，河面上覆盖着一层薄薄的油，河面还漂着一些垃圾，连河底下也有垃圾，原本在这嬉戏的小鱼也不见了，连河底的沙石都看不清了，还有刺鼻的味道。 我和妈妈、姐姐商量好，决定清理河床。首先，妈妈找来钩子和垃圾袋，然后，我们把河里的垃圾一点点的钩上来，最后，我们把垃圾放到垃圾袋里，打算送到垃圾站去。虽然我们已经汗流浃背了，但是我们很满足。 水资源是我们的生命，没有水我们就不会活在这个世界上，但光

【篇一】 水是生命的源泉、工业的血液、城市的命脉。水是人类生活中不可缺少的重要资源。 如果把家中的洗衣机换成节水洗衣机，一年能节出714个昆明湖；把家中的马桶换成3/6升双键马桶，一个家庭月节水近2000升左右；改掉不良用水习惯，能节水70%左右。 一滴水，微不足道。但是不停地滴起来，数量就很可观了。如果中国每人每天节约一滴水，就是13亿滴水，也就是1300升水，那么一年可以节约474500升水，它可以给一个城市提供一年的居民总用水量，它可以让一片荒原变成绿地。所以，节约用水要从点滴做起。 其实只要我们注意身边的点滴小事，节水很容易做到。像清除餐具上过重的油污时不要直接用洗涤剂洗，先用纸擦拭，然后再清洗，这样可以节省一半以上的用水。洗手时，用盆洗比用水长流的方法更节省水，洗涤蔬菜水果或洗碗时也一样，开着水龙头不间断的冲洗非常费水，间断冲洗就能节约水。把用过的水存下来还可以再次利用。家庭中洗衣机的用水量大，为了节水，生产厂家和科研人员都下足了功夫，要在保证洗干净衣服的前提下尽可能的节约用水。这种倾斜的造型并不是为了美观或标新立异，10度的斜面设计自有它的道理。洗衣筒歪了10度后，它的水位就相对加深了，能达到较大水量的洗涤效果。所以它省水。洗衣机设定的程序一般都是一次洗涤，两次漂洗，水主要都耗费在漂洗上了。如果不用洗衣粉，不就能省下漂洗的水了吗？ 人人都需要水，人人都要珍惜水。节约用水，从身边的小事做起，从每一滴水做起，为节约水资源作出贡献吧！ 【篇二】 随着人类科技的发展，那些清澈透亮的河水、湖水似乎离我们远去了，取而代之的则是漂满垃圾的脏水。阳光下，再也闻不到来自水的清香了，只能嗅到一股股恶臭。 城市里的水道上总会有许多垃圾：水面，塑料袋与饮料瓶你拥我挤地和荷花浮萍争地盘；水中，一根根烟蒂漂浮着嬉闹游玩；水底，鱼儿们穿梭于纸团纸屑之间，玩得不亦乐乎。水，已全然失去了以往的姣好容颜，当垂柳依依多情地想照“镜子”时，却发现“镜子”已肮脏无比，忙缩回了头；当蜻蜓款款飞来想点水起舞时，却发现水已恶臭不已，忙飞向花丛；当燕子南飞归来想找昔日好友时，却发现好友已狼狈不堪，忙跌跌撞撞飞走了……造成这一切的罪魁祸首，可是我们人类自己呀！ 水，对地球上的生物来说，是生命的根本；水的干净与否，决定着我们的生死存亡。所以，现在的各个河段、湖泊上，总会发现一队队划着小船，辛勤打捞水上漂浮物的清洁工叔叔阿姨们。橘色的衣服是他们的标志，清亮的汗水挥洒着信念的光辉。 水资源的减少让人们有了觉悟，但只有少数人能做到保护水资源，多数人都未能清楚认识到保护水资源的重要性。不过，“五水共治”行动已经轰轰烈烈的开展，各种治水方案也已在实施中。相信在不久的将来，清澈的水源将重新呈现在我们面前。 让我们从我做起，充分发挥个人和集体的力量，保护水资源，让我们的地球和我们生命都能得到净化！

英语作文范文 写作范文《保护水资源》 Directions: A. Title:Globle Shortage of Fresh Water B. Word Limit: about 200 words C. Your composition should be based on the Outline given in Chinese below: 1. 人们认为淡水是取之不尽的（提示：雨水，河水，井水） 2. 实际上淡水是短缺的（提示：人口增加，工业用水增加，污染严重） 3. 我们应当怎么办（提示：节约用水，开发新水源） 例文： Global Shortage of Fresh Water People often think that water will never be used up. There is plenty of water, such as rain, water from the rivers and wells. It seems as if water is always available around us and we never have to worry about water shortage. In fact water is rather limited on the earth. With the rapid increase of population and fast development of
industries, water is more needed than before. At the same time, a large amount of water has been polluted and wasted every day. Some big cities in China are facing the problem of water shorage already. There, water supply is controlled and industry has been restrained. What should we do about the water shorage? I think, first, the people should be made aware of the real situation about the water. Everyone should consciously save on water and certain law should be made that no water will be polluted. We have to protect the existing water resources and develop new ones. In this way I believe that our cities will not be thirsty for water in the future.
