[自然作文]关于水的重要性的作文3篇关于水的重要性的作文3篇当我们扭开水龙头,无情的浪费水时、当我们高兴的玩水时我们有没有想过水源会不会干涸。
水是生命之源,我们所拥有的水资源并不是无限的。
那一次,我看了一篇文章,它使我深受启发。
文章讲的是:在一个水源丰富、美丽富饶的地方,人们丰衣足食,显然不为水源上的事担忧。
可正是因为他们不担忧水源上的事,而毫无止境的浪费水源每次,人们如果看到自己从井里取来的水有一点不新鲜、不满意,就会把这可贵的水泼到水沟里,哪怕满满一盆水。
还有,他们那儿小孩子最爱玩水了,并且消耗量非常大,每天就要消耗6盆以上的水时间长了,这个水源丰富、美丽富饶的地方渐渐的变成了一片水源匮乏旱灾严重的灾区。
地球上的水很多很多,据估计,水的总体面积约为13.8亿立方千米。
如果将这些水平均分布于地球表面,相当于地球整个表面覆盖着一层平均深度为2650米的水。
但是十分可惜,这些水98%是咸水,主要分布在海洋中。
据我从书上得知:人们所使用的水几乎都是淡水。
但是淡水只占地球水总量的2%,因此地球上的人们能吃的水源少的可怜。
正因为这样,我们更要保护好水资源,把保护水资源,从我做起这一句话宁记在心。
当然,我们也不能光说不做。
当我们扭开水龙头时要记住些什么、当我们看到别人浪费水资源时又要劝告些什么。
水是生命之泉,人体的百分之七十之前都是水,也由此可见水对于我们来说是多么的重要,我们的生命都依赖于水。
但是喝水也是十分的讲究了,喝对了水那就人就有益处的,如果不正当的喝水,那么效果可能就适得其反了。
早上起床喝一杯温开水那是必需要的,它不但能清理一下你的肠道让你排排毒素,也能让你有精神,开始崭新的一天,在中午喝一杯也是非常有好处的,它能够帮助你解脱疲劳的状态让你的心情能够放松下来,如果你吃完饭后常常有罪恶感的话,那么半个小时后喝杯水吧,它能够让你减轻负担也能够帮助你减肥,晚上睡觉之前喝杯水也是好的,它能够帮助你排毒消化又能够增进血液循环。

水是生命的源泉作文水是生命的源泉作文5篇在平凡的学习、工作、生活中,大家或多或少都会接触过作文吧,作文是经过人的思想考虑和语言组织,通过文字来表达一个主题意义的记叙方法。
怎么写作文才能避免踩雷呢?以下是店铺收集整理的水是生命的源泉作文,欢迎大家分享。
水是生命的源泉作文1水,是万物的生命之源。
因为有水,才使生命的种有了生存的温床。
生命由此萌发、延续,不断地进化,才使地球变得美丽起来。
“水是生命之源,我们要保护每一滴水。
”这句话说得没错,如果没有了水,地球就会干裂;如果没有了水,我们人类就可能渴死;如果没有了水,就没有了我们这个美丽的世界。
我们要爱惜每一滴水,爱惜地球母亲每一滴眼泪。
如今的华夏大地,已经严重缺水,淡水资源总量为28000亿立方米,占全球水资源的6%,仅次于巴西、俄罗斯和加拿大,居世界第四位,但人均只有2200立方米,仅为世界平均水平的1/4、美国的1/5,在世界上名列121位,是全球13个人均水资源最贫乏的国家之一。
扣除难以利用的洪水泾流和散布在偏远地区的地下水资源后,中国现实可利用的淡水资源量则更少,仅为11000亿立方米左右,人均可利用水资源量约为900立方米,并且其分布极不均衡。
到20世纪末,全国600多座城市中,已有400多个城市存在供水不足问题,其中比较严重的缺水城市达110个,全国城市缺水总量为60亿立方米。
水,在岁月的年轮里流淌,是水造就了生命的奇迹,是水使我们的生活多姿多彩,是水使我们的生命能一直延续,水的循环是自然界最伟大的循环之一。
它永远是陈旧的,又永远是崭新的。
人们会因为石油而发生战争也会应为矿产资源而大动干戈。
但是,如果这个世界没有水,世界上最珍贵的的钻石也一文不值,水是生命之源,无法代替。
水是地球上最有价值的物质。
然而,因为农业和耕地发展,人们滥用水资源,水在日益减少。
无法想象,如果地球上已经没有一滴水,那会变成怎样惨不忍睹的画面哪?真的不敢想象啊!所以,我们不能再等了。

然而,随着人类不断的开发和掠夺,水资源已经出现了短缺的情况,这使得人们更加意识到水的重要性,也让人们深刻地认识到了水资源的宝贵性,因此保护水资源,合理利用水资源,已经成为了人类共同的责任。
我们需要认识到,水是非常重要的饮品。
人体中70%以上都是水,正常人每天需要饮用2-3升的水,因为水能够帮助人体代谢废物,维持人体的平衡,调节身体的温度,并且还有助于各种营养物质的吸收和分解,如果长期缺水,人体将会出现很多不良症状,包括口渴、皮肤干裂、头痛、便秘、疲劳等,因此,保持身体的水分是非常重要的。
水的重要性还体现在教育和经济上。
在学校、公共场所等地方,净水器和饮水机已经成为了必备设备,这不仅是为了保证师生员工的健康,还有有利于教育的有效开展。
在经济方面,水是一个非常宝贵的资源。
水能够被用于农业生产、工业生产和家庭生活中的许多方面,而随着世界人口的增加,对水资源的需求也在不断增加。
因此,我们需要从经济和社会发展的角度来认识水的重要性,保护水资源、合理利用水资源已经成为了国家发展的重要任务之一。
水资源的保护和管理是每个人的责任。
我们可以从自己身边做起,如关闭水龙头、定期检查水管、节约用水等。
为了保护水资源,还需要采取环境保护措施,定期清理水体,加强水污染治理,采用环境友好型的工业生产和农业生产方式等。
只有这样,才能保证未来世代也能像我们一样享有清洁的水资源。
水是生命之源,人类离不开水。
在日常生活中,我们需要更加重视水的利用和保护,保护水资源,使之可持续利用,这是我们每个人的责任。
只有这样,我们才能真正守护好这个地球上最重要的资源之一,保证人类能够长期稳定、安全地生存下来。
以水的重要性为题写一篇英语作文全文共3篇示例,供读者参考篇1The Importance of WaterWater is essential for all forms of life on Earth. It is a vital resource that plays a crucial role in sustaining life and supporting ecosystems. Without water, life as we know it would not be possible. In this essay, we will explore the importance of water and why it is essential for the survival of all living beings.First and foremost, water is crucial for hydration. Our bodies are made up of approximately 60% water, and staying properly hydrated is essential for maintaining good health. Water helps to regulate body temperature, transport nutrients and oxygen to cells, and remove waste products from the body. Without an adequate supply of water, we would quickly become dehydrated and our bodies would not function properly.In addition to its importance for human health, water is also essential for the environment. It is a key component of ecosystems and provides habitat for a wide variety of plants and animals. Water is necessary for the growth of crops and supportsthe food chain by providing a source of hydration for all living organisms. Without water, many species would not be able to survive, and ecosystems would collapse.Furthermore, water plays a critical role in agriculture and industry. It is used for irrigation to grow crops, generate hydropower, and produce goods and services. Water is also essential for transportation and sanitation, helping to facilitate trade and improve public health. Access to clean and safe water is a basic human right, and ensuring that all people have access to this vital resource is crucial for promoting sustainable development.Despite the importance of water, this precious resource is facing numerous challenges. Climate change, pollution, overuse, and contamination are putting a strain on water supplies around the world. In many regions, water scarcity is becoming a critical issue, leading to conflicts over access to water and threatening the livelihoods of millions of people.In conclusion, water is a fundamental resource that is essential for the survival of all living beings. It is crucial for human health, the environment, agriculture, industry, and society as a whole. As the global population continues to grow and demand for water increases, it is more important than everto protect this precious resource and ensure that it is managed sustainably for future generations. By valuing and conserving water, we can ensure a healthy and prosperous future for all.篇2The Importance of WaterWater is one of the most essential elements for life on Earth. It covers about 71% of the Earth's surface and is crucial for the survival of all living organisms. Without water, life as we know it would be impossible.One of the primary reasons water is so important is that it is necessary for hydration. Our bodies are made up of about 60% water, and we need to consume a certain amount of water every day in order to stay healthy. Water helps to regulate our body temperature, aids in digestion, and carries nutrients to our cells. Without an adequate supply of water, our bodies would not be able to function properly.Water is also crucial for agriculture. Without water, crops would not be able to grow, and we would not have enough food to feed the world's population. Farmers rely on water to irrigate their fields and provide a consistent water supply for their crops.Water is also used in livestock farming to provide animals with drinking water and to keep them healthy.In addition to its importance for human and animal life, water is also crucial for the environment. It plays a vital role in the water cycle, which helps to regulate the Earth's climate. Water absorbs heat from the sun and releases it back into the atmosphere, helping to maintain a stable climate. Water also helps to support ecosystems by providing habitats for plants and animals.Despite its importance, water is a finite resource. It is estimated that only about 3% of the Earth's water is freshwater, and much of that is locked up in ice caps and glaciers. As the world's population continues to grow, the demand for water is increasing, leading to water scarcity in many parts of the world. It is essential that we take steps to conserve water and protect this valuable resource for future generations.In conclusion, water is one of the most important substances on Earth. It is essential for human life, agriculture, and the environment. We must all do our part to conserve water and ensure that this vital resource is available for generations to come.篇3The Importance of WaterWater is one of the most important substances on Earth, essential for the survival of all living organisms. It covers about 71% of the Earth's surface and is found in rivers, lakes, oceans, and even in the air we breathe. Without water, life as we know it would not exist. In this essay, we will explore the many reasons why water is so crucial and indispensable.Firstly, water is vital for human health and well-being. Our bodies are made up of about 60% water, and it plays a crucial role in various bodily functions, such as digestion, circulation, and temperature regulation. Water helps to transport nutrients and oxygen to cells, remove waste products, and maintain electrolyte balance. It is also essential for hydration, as the human body can survive without food for weeks but only a few days without water.Furthermore, water is essential for agriculture and food production. Without water, crops would not grow, and animals would not have anything to drink. Irrigation systems rely on water to provide the necessary moisture for plants to thrive. Inaddition, water is also used in food processing, cooking, and cleaning, making it an integral part of our daily lives.In addition to its importance for human health and food production, water also plays a crucial role in the environment. Rivers, lakes, and oceans are home to a vast array of plant and animal species, and water is essential for their survival. Wetlands provide habitat for many species and help to regulate water flow and filter pollutants. Water is also crucial for maintaining biodiversity and ecosystem balance.Moreover, water is essential for industry and economic development. Many industries rely on water for manufacturing processes, cooling systems, and transportation. Water is also used in energy production, such as hydropower and nuclear power plants. Without water, many industries would not be able to operate, leading to economic stagnation and job losses.In conclusion, water is a precious resource that is essential for human health, food production, environmental sustainability, and economic development. It is our responsibility to conserve and protect water sources for future generations. By taking steps to reduce water wastage, pollution, and overuse, we can ensure a sustainable and healthy future for all. Let us appreciate theimportance of water and strive to preserve this invaluable resource for generations to come.。

水的重要性作文
导读: 水的重要性作文(一)
当我们扭开水龙头,无情的浪费水时、当我们高兴的玩水时……我们有没有想过水源会不会干涸。
水是“生命之源”,我们所拥有的水资源并不是无限的。
那一次,我看了一篇文章,它使我深受启发。
文章讲的是:在一个水源丰富、美丽富饶的地方,人们丰衣足食,显然不为水源上的事担忧。
可正是因为他们不担忧水源上的事,而毫无止境的浪费水源——每次,人们如果看到自己从井里取来的水有一点不新鲜、不满意,就会把这可贵的水泼到水沟里,哪怕满满一盆水。
还有,他们那儿小孩子最爱玩水了,并且消耗量非常大,每天就要消耗6盆以上的水……时间长了,这个水源丰富、美丽富饶的地方渐渐的变成了一片水源匮乏旱灾严重的灾区。
地球上的水很多很多,据估计,水的总体面积约为13.8亿立方千米。
如果将这些水平均分布于地球表面,相当于地球整个表面覆盖着一层平均深度为2650米的水。
但是十分可惜,这些水98%是咸水,主要分布在海洋中。
据我从书上得知:人们所使用的水几乎都是淡水。
但是淡水只占地球水总量的2%,因此地球上的人们能吃的水源少的可怜。
正因为这样,我们更要保护好水资源,把“保护水资源,从我做起”这一句话宁记在心。
当然,我们也不能光说不做。
当我们扭开
水龙头时要记住些什么、当我们看到别人浪费水资源时又要劝告些什么……
水的重要性作文(二)
今年,云南遭受百年难遇的罕见旱灾,到处缺水,到处一片惨景。
人们多么渴望老天开开眼,下一场大雨呀!可是,我一直弄不明白人为什么要喝水?不喝水又会怎么样呢?
我决定三天不喝水来做做实验。
第一天居然什么事儿也没有,我便说道:“切,不喝水有什么了不起,我一个月不喝水都没任何问题!”第二天,口开始干了,但还是没有多大的问题,饭吃饱就没有关系了。
到了第三天,实在不行,我口干得只有咽口水,坚持不下去了,我拿起五瓶矿泉水,“哗哗哗”,水就像溪水似的流进我的肚子,吓得老妈直瞪大了眼睛。
不到五分钟,我全喝光了,然后舒坦的说:“水真好,真好,渴死我了!”经过这一次的实验,我虽明白了水对我们很重要,但是还没弄明白人为什么离不开水。
我决定去问博学多才的爸爸!
我跑去书房,问道:“爸爸,人为什么离不开水?”爸爸捋捋胡子,装成一个大学问家的样子,说道:“这个嘛,是因为组成人体的细胞需要水来维持。
”我摇摇头:“不明白,您能说仔细点吗?”“水是构成生物体的基本成份。
不论是动物还是植物,均以水维持最基本的生命活动。
人可数天无食,不可一天无水,所以水是生命之源泉,水也是人类最必须的营养素之一。
”我又问道:“那为什么人体需要水,而不需要木头、石头这些东西呢?”爸爸有解释道:“水是吸收营养,
输送营养物质的介质,又是排泄废物的载体,人通过水在体内循环完成着新陈代谢过程。
在这个过程中水还具有人体散热,调节体温,润滑关节和各内脏器官等等作用,它对人类的生命至关重要,如果失水10%——20%,就会危及生命。
所以说,水是生命的源泉一点儿都不过分!”
我明白了,我又问道:“那人每天究竟需要多少水呀?”爸爸挠挠脑门,说道:“这个……具体我也不知道,自己去查阅一下资料吧!”
后来在资料上,我翻阅到:正常人每天从饮食和饮水中摄取的水分,成年人大约为2500毫升每日,摄入水量的多少一般应与人体每日排水量的平衡。
例如成人每日尿量平均约1500毫升,皮肤和呼吸道排出约800毫升,粪便100—200毫升,总计约2500毫升。
古今中外都有大量的记载,不论是“长寿村”,还是一些地方发生的地方病,原因都与当地的饮水有关,好水带来了健康,污染水带来了疾病。
所以大家一定要保护水资源!
水的重要性作文(三)
我们每天都会和水打交道,水安安静静,任我们舀取,任我们泼洒,不曾言语。
只有有一天,她突然开了口。
水叙述说: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,可人类总是破坏我,滥用我。
这样既会导致水源的枯竭,又会严重影响生态环境。
在日常生活中,我时时刻刻都能派上用场。
如:人们的身体中必须含有我;人们做饭、洗衣服都得用我;植物也需要我,有了我,
蔬菜瓜果才能长得更鲜、更嫩;当发生干旱时,我可是最有用的……总之,我是一种人类离不开的物质。
我尽量地改变自己,使自己变得更纯洁,让人们用得更舒心,更放心。
可是,人类点儿也不为我着想,他们只顾自己的爽快。
有时,人们用完水后,不关水龙头,让我白白地流失了。
全球有那么多人,一人浪费一滴水,合起来就是几吨。
这可苦了我,全球的淡水本来就不多,照这样下去我可应付不过来。
所以人类只有节约用水,水资源才能得到保证。
人类不光浪费我,而且破坏我。
工厂排放的污水就够呛了,人们还往河里扔垃圾。
时间一长,原本清亮的我,现在变脏了,变臭了,我的朋友小鱼、小虾也相继死去。
我恨人类,我是人类忠实的仆人,可遭遇了不公平的待遇。
所以,我一气之下,也会发点洪水,闹干旱时不救他们,给他们一些警告。
人类呀,醒悟吧!
听了水的话,我感慨万千。
是呀,水是生命的源泉,是哺育大地的乳汁,世界离不开水,人类离不开水。
就拿我的家乡民勤来说吧,民勤原来是一个可牧可渔的地方,可由于没有了河水,再加上人们的破坏,民勤的水资源迅速减少。
人们不得不大量抽取地下水以解决农田灌溉、人畜饮水的困难,从而导致地下水位急速下降,使民勤成了一个甘旱地区,成了风沙的发源地。
还有,我们的母亲黄河曾几次断流
许多人还没有认识到节约用水的重要性,可是单单就在我国还有许许多多跟我们同龄的小朋友喝不上一口干净的,哪怕在我们眼里
是很脏的——水!更有些人为了达到自己的目的,胡乱挖掘、肆意抽取被认为如同人类血管般重要的地下水!导致地球的含水层与粘土层压缩变形,地面沉降和地裂缝等地质灾害的发生,造成了不可估量更是无法挽回的损失!而这一切的使作俑者便是人类自己!更有甚者,还不能认识到自己的错误。
有些人一边咒骂附近的河流、池塘的水太脏、太臭,一边却还往里面倒各种垃圾等等。
这些人是可耻、也是可悲的!
朋友们,你可曾想过未来的某一天,工厂烟囱再也隐匿不了那些黑烟,小河不再清澈,没有所谓的森林、树木,没有种种……因为没有水。
你们敢想象吗?所以,保护水资源吧!。
