水资源现状
地 球 上 97.5% 的 水 是 咸 水 （ 其 中 96.53% 是 海 洋 水 ， 0.94%是湖泊咸水和地下咸水），又咸又苦，不能饮 用，不能灌溉，也很难在工业应用，能直接被人们生 产和生活利用的水少得可怜，仅有2.5%的淡水。而在 淡水中，将近70%冻结在南极和格陵兰的冰盖中，其 余的大部分是土壤中的水分或是深层地下水，难以供 人类开采使用。江河、湖泊、水库及浅层地下水等来 源的水较易于开采供人类直接使用，但其数量不足世 界淡水的1%，约占地球上全部水的0.007%。

马桶：应安装可随手控制出水量的马桶配件，
大便、小便可用不同的水量冲洗。未采用节水配 件的普通马桶，可在水箱中放入一支可乐瓶或将 浮球杆向下弯15度，可减少水箱的储水量，进而 减少每次冲水量。不要把烟灰、剩饭、废纸等倒 入马桶，因为用水冲掉它们可能要冲几次。

资源污染比
我国浅层地下水资源污染比较普遍，全国浅层地下水大约有50% 的地区遭到一定程度的污染，约一半城市市区的地下水污染比 较严重。由于工业废水的肆意排放，导致80%以上的地表水、地 下水被污染

At work, we can use water to:
Save water
Water is valuable, like liquid gold. We can’t live without it. At home, we use water to brush teeth, wash face, clean houses and so on. At work, we use water to grow vegetables, produce electricity, make things in factories and so on.
Finally, we should do our best to ask people around us to save water.
It’s our duty to save water. Please don’t make our tear the last drop of water.
Let’s do our best to save water, or the Earth will become desert.
grow vegetables produce electricity
make things in factories
《Water》教案
《Water》教案一、教学目标1.知识目标：了解水的基本性质和作用，理解水循环的过程和意义；了解处理水污染的方法和技术，掌握自我保护的方法。
2.技能目标：能够清晰表达自己关于水的认知和思考，掌握调查和收集资料的方法，动手制作节水工具。
3.情感目标：培养学生珍惜和节约水资源的意识，真正体会水对人类生存和发展的重要性，增强保护环境、保护水资源的责任感。
二、教学内容本节课是《Water》一课，课文着重介绍了水的基本性质、作用和意义，以及处理水污染和节水等方面的知识。
教学内容如下：1. 水的基本性质•水的物理性质：透明、无色、无味、无臭；熔点和沸点高；比热大，热容量大。
•水的化学性质：不对空气中二氧化碳产生化学反应；与酸、碱反应；对于其他物质有良好的溶解度。
2. 水的作用和意义•生命必需：人体70%以上是水，水是人体的重要组成部分。
•社会发展：工业生产和农业生产都需要用水；交通运输也需要水上交通。
•生态平衡：水是自然生态系统的重要组成部分，对于水生生物和陆地生物的生存都很重要。
3. 水循环•蒸发：水体受热蒸发成水蒸气，升入大气层。
•凝结：水蒸气遇冷遇到微小的尘粒而凝结成云雾，过程称为凝结。
•降水：水滴积聚到一定大小后落回地面，过程称为降水。
•渗入：部分降水渗入地下，成为地下水，部分汇入河流和水库。
•再蒸发：地面和水面上的水被太阳照射，再次蒸发，又形成水蒸气。
4. 水污染的处理•生物处理方法：利用大量的微生物进行水质净化，去除污染物。
•化学处理方法：利用化学药剂去除水中污染物，如氧化剂、还原剂和消毒剂等。
•物理处理方法：采用过滤、吸附、沉淀等物理效应，将污染物与水分离。
5. 节水•减少用水量：例如修复漏水设施，使用低流量水龙头和卫生器具，优化灌溉系统，减少浴缸用水量等。
•提高用水效率：例如收集雨水以便用于浇灌植物，将洗涤、冲洗等水处理后再次使用，选择高效节水的家电设备等。
•变革用水习惯：例如短时间洗澡和关闭水龙头，不随意泼洒和浪费水。
