我们的生活离不开水800字作文篇4老大、老二、老三和老四是一个单位的,经常在一起办事。
有一天,老大接到上头的命令,被派去沙漠里的一个村庄送水并帮他们找水。
接到命令后,他们几个第一时间整理好行李,乘坐一辆吉普车前往沙漠。
虽然目的地离的不是很远,但因遍地是沙丘,他们一路颠簸,好不容易才找到了村庄。
老大他们跳下车,让司机先回去。
他们走到村庄旁,但总觉得少了什么。
“谁知道我们是不是忘了什么呀?”老大问众人。
老二、老三摸了摸额头,一下子无言以对,这时老四叫了起来:“政府让我们带给村子的两桶水没拿下来!”众人一拍脑袋,都想了起来。
“这可咋办呀?”老三急问。
“只能用我们的那部卫星手机了。
”老大说,可老大摸遍了全身也没找到。
要知道,哥几个就只有这一部手机。
没法子,兄弟几个只能去挖地找水源了。
他们挖呀挖,找呀找,几乎挖遍了村外的每一寸土地,可就连个仙人掌的根也没找到。
没多久,老大他们把身边仅有的水都喝完了。
就在大家绝望之际,只听老二叫了起来:“大家快看!快看!那个山丘那里好像有口井。
”大家抬头一看,以为老二是渴昏了,猜测那只是个海市蜃楼。
但走近一摸,确实是一口井。
几个人顿时欣喜若狂,纷纷拿来水桶去提水。
井水不多,但还是装满了四个桶,当大家即将离开时,老三又有了新发现:“大家快看山顶上,那团红色的东西是什么?”众人一看,也很好奇。
于是四个人扛起水桶跑向山顶,准备一看究竟。
四人来到山顶的那团红色东西旁,发现竟是一辆车,不过已经被沙子埋住了。
众人二话不说拿出水扑在车上,把沙子清除掉。
不一会儿,车子整个儿露了出来,眼尖的老四还发现车里面有许多桶水,忙招呼大家看个究竟。
看到这么多水,大伙儿眼睛直发光。
这时候,老大说:“我们给自己留一些,再把剩下的水高价卖给村里的人,每桶200元,大家觉得如何?”其余几人一听,纷纷赞同。
大家抢着拉开车门冲进去抢水。
一时间,撕打声、惨叫声、破碎声接连不断。
没过多久,他们四个就倒在了车旁,水也全部流了出来。
人类离不开水的原因水是生命之源,对于人类来说,离开水是无法生存的。
水在人类的生活中起着至关重要的作用,不仅是人体的必需品,同时也是农业、工业和生态环境的基础。
以下将详细探讨人类离不开水的原因。
人体的构成离不开水。
人体约有60%至70%的组织和器官是由水构成的,水是维持体温、运输营养物质、排除废物和保持细胞功能正常运作的基础。
人体每天都需要摄入足够的水分来满足这些生理需求,所以水对于人类生存至关重要。
水是农业的基础。
农业是人类最重要的经济活动之一,而水是农业生产的基础条件之一。
农作物需要水来生长,水分能够促进植物的光合作用,从而合成有机物质。
在干旱地区,如果没有足够的水供应,农作物的生长将受到严重影响,最终导致粮食短缺和饥荒。
水是工业发展的重要支撑。
工业生产过程中需要大量的水来冷却设备、清洗物品和作为化学反应的媒介。
许多工业部门如钢铁、石化和纺织等都离不开水。
水资源的充足性和质量对于工业发展至关重要,它们直接影响着工业生产的效率和质量。
水是维持生态环境平衡的重要因素。
水是河流、湖泊、海洋和地下水等生态系统的组成部分。
它们提供了许多生物栖息地,维持了生物多样性的平衡。
水还能够调节气温,吸收大气中的二氧化碳,起到减缓气候变化的作用。
因此,水的存在和质量对于维护生态平衡和保护生物多样性至关重要。
水在人类的生活中扮演着重要的角色。
水不仅用于饮用、洗涤和做饭等日常生活用途,还用于交通、娱乐和旅游等方面。
许多城市和乡村的发展都与水资源的利用和保护密切相关。
因此,水的存在和利用对于人类的生活质量和社会发展至关重要。
水是人类离不开的重要资源。
它不仅是人体的构成要素,还是农业、工业和生态环境的基础。
水的存在和利用对于人类的生存和发展至关重要。
因此,我们应该珍惜水资源,合理利用,同时加强水资源的保护和管理,确保人类能够继续依赖水来维持生活的正常运转。

】二、走进水的世界,了解水的用途。
1、水与生活。
让学生说一说为什么我们的生活离不开水,生活中哪些地方用得到水,来夸夸水的功劳,小组讨论,学生畅所欲言。
(洗澡,冲厕,洗衣,做饭……)2、水与动物、植物的关系。
小结:水是生命之源,没有水,人类就无法生活;没有水,就没有动物、植物,水是我们的好朋友,我们的生活离不开它。
3、水与社会生产的关系。
【设计意图:让学生知道我们的生命离不开水。
人类的生活中有直接用水的地方,也有很多看不到,间接用水的地方。
动物,植物,整个地球的生命之源就是水,体会水的是我们生活中不可或缺的重要资源。
】三、设想没有水的世界。
水对我们既然这样重要,那么大家做一个假设---如果生活中没有水的话,会发生什么可怕的事情?1、学生四人小组讨论,自由发言。
2、老师小结:吃不到饭,植物会枯死,人会渴死,衣服洗不成……等等,根据科学家讲, 一个人一天至少需要8杯水,不吃饭可以活7天,不喝水只能活3天。
中班活动我们的生活离不开水各位读友大家好,此文档由网络收集而来,欢迎您下载,谢谢中班活动:我们的生活离不开水设计思路:水和我们的生活密不可分,孩子们对水也充满了极大的兴趣,可是孩子们对于水能不能用完充满了疑问,我想通过这样一个活动,让孩子通过想想、说说、看看的过程中了解水资源是有限的,产生保护水资源和养成节约用水的意识。
活动目标:1、能积极参与讨论,并能清楚的表达自己的想法。
2、懂得水资源是有限的,增强保护水资源、节约用水的意识。
活动准备:淡水资源的图片、地球仪、图片(水龙头滴水情况)、情景视频活动过程:一、提出问题1.最近我们在学习有关水的知识,讨论有关水的问题,现在我们来讨论一下,我们的生活能离开水吗?为什么?2.小结:恩,对呀,我们人类和动物如果一直不喝水会渴死,植物如果一直不浇水会枯萎,所以说水是生命之源,没有水就没有生命。
二.讨论1.那你认为水用的完吗?2.有人认为用得完,有人认为用不完,我们小朋友肯定都有自己的理由,那到底水用得完吗?教师出示水龙头图片:老师这里有两幅图片,谁能说说看,这两幅图片表示什么意思?图片一表示水是用的完的,图片二表示水是用不完的。
现在我们来分成2队,认为水用得完的小朋友参加图片一对,认为水用不完的小朋友参见图片二队。
3、幼儿分组。
教师:你们是什么队?你们认为水用得完吗?那你们呢?4.幼儿自由讨论{用得完:人口多,污染,浪费水…….{用不完:水很多,下雨,下雪,江河很多,大海…….5、出示图片:老师这里有一张水资源的图表,这圆形图片就表示地球上的水资源,蓝色的是海水,红色的是淡水。
虽然地球上的水资源很丰富,但是大海里大海的水是咸的不能用,但是让人们可以利用的淡水资源却越来越少了,所以我们每个人都要节约用水。
三.判断1.老师这里有一些情景,请你们看看他们这样做对吗?为什么?2、教师播放视频片段。
教师:这个小朋友的做法对吗?为什么?应该怎么做?3、那你有什么节约用水的好办法呢?教师小结:水资源是有限的。
