Water—Our Precious Treasure
Water is the source of life, and it is one of the most precious things on Earth. Nothing can survive without water.
Water plays a key role in our daily lives. We drink it to stay healthy, use it to cook meals and wash clothes. Farmers need water to water crops, and factories use it to cool machines. For nature, water helps plants grow and provides homes for aquatic animals. However, fresh water is limited—only about 2% of the Earth’s water is fresh, and we can only use a small part of it. What’s worse, some people are wasting and polluting water.
We must save water right now. We can take shorter showers, fix dripping taps, and reuse water to water plants. Let’s value every drop of water and protect our common home!
【译文】
水——我们珍贵的财富
水是生命之源,也是地球上最珍贵的东西之一。没有水,万物都无法生存。
水在我们的日常生活中扮演着关键角色。我们喝水保持健康,用水做饭、洗衣服。农民需要水灌溉庄稼,工厂用水冷却机器。对于大自然来说,水帮助植物生长,为水生动物提供家园。然而,淡水是有限的——地球表面只有约2%的水是淡水,而我们只能使用其中很小一部分。更糟糕的是,有些人还在浪费和污染水。
我们必须立即节约用水。我们可以缩短淋浴时间,修理滴水的水龙头,还可以重复用水浇花。让我们珍惜每一滴水,保护我们共同的家园!

The Journey of Tap Water

【拓展1范文】
The Journey of Tap Water
Have you ever wondered where tap water comes from? Its journey is long and interesting.
First, water from rivers, lakes or rain falls into reservoirs. Then it is sent to water treatment plants. There, people clean it by adding chemicals to remove dirt and germs. After that, the clean water travels through underground pipes to our homes, schools and offices. When we turn on the tap, the water is ready for use. After we use it, the dirty water goes through other pipes to sewage treatment plants. It is cleaned again before being returned to rivers or the sea, and the cycle starts over.
Every drop of tap water comes a long way. We should never waste it.
【拓展1译文】
自来水的旅程
你有没有好奇过自来水来自哪里?它的旅程漫长而有趣。
首先,来自河流、湖泊或雨水的水流入水库。然后,水被送往水处理厂。在那里,人们通过添加化学物质来清洁水,去除污垢和细菌。之后,干净的水通过地下管道输送到我们的家、学校和办公室。当我们打开水龙头时,水就可以使用了。我们用完水后,脏水通过其他管道流向污水处理厂。它会被再次清洁,然后流回河流或大海,循环重新开始。
每一滴水都来之不易,我们永远不应该浪费它。

Dear Family,
Water is precious, but we are wasting too much of it. To protect this important resource, I want to suggest some water-saving habits for all of us:
First, we can reuse the water from washing vegetables to water the flowers—this saves a lot of water. Second, always turn off the tap tightly when we are not using it, especially when brushing teeth. Third, let’s use water-saving appliances, like low-flow showerheads. We don’t need to use too much water to clean dishes or clothes.
Every small action counts. If we work together, we can save a large amount of water. Let’s start today and be water-saving heroes!
【拓展2译文】
亲爱的家人:
水很珍贵,但我们浪费得太多了。为了保护这一重要资源,我想为大家建议一些节水习惯:
首先,我们可以把洗菜水用来浇花——这能节约很多水。其次,不用水的时候一定要把水龙头关紧,尤其是刷牙的时候。第三,我们使用节水器具,比如低流量淋浴头。清洗餐具或衣服时,我们不需要用太多水。
每一个小小的行动都很重要。如果我们一起努力,就能节约大量的水。让我们从今天开始,成为节水小卫士吧!
