Water-saving tips 　　We all need water in our daily
lives， so we should not waste it.
There are many ways to save water.
We can make a big difference if we
start today！ 标题
Para 1：开篇点题(强调
节水的重要性与号召行
动)。
At home：
　　Remember to turn off the tap when brushing teeth or washing your face. This can save a lot of water in a year. Try to take quick showers instead of long baths. It uses much less water. We can also collect rainwater on rainy days. Then we
can use it to water plants.
In school：
　　Turn off the tap tightly after washing hands. Don’t leave the water running. When you drink water， only take as much as you need. Don’t fill your bottle too full if you can’t finish it. We can also have class meetings about saving water. We can talk about why water is important and share good ideas.
主体
Para 2&Para 3：分场景列举具体、可行的节水措施(采用“总—分”结构，按照生活场景分类说明，使条理清晰，易
于读者理解和实践。)
Saving water is everyone’s
responsibility. Let’s start from small
things and work together to protect
our precious water resources. Every
drop of water counts！ 结尾升华
Para 4：总结主旨并发出
倡议(呼吁大家积极行

体节水方式。


We should try to use less water when washing dishes. For
example， we can fill one basin to wash them all.
(二)细节升级。(增加可操作性)

状(含咸水、淡水、饮用水各1点)。





Let’s talk about the water facts from the programme. About 70
％ of the Earth’s surface is water， but 97％ of it is salt water
that we can’t drink. Most of the 3％ fresh water is ice， not
available for use. We can only use about 0.5％ of the Earth’s
water as drinking water.
一、开场句。
Let’s talk about the water facts from the programme.
二、描述数据。(引用具体百分比)
句式参考：
The programme says that …， so …
It mentions that only …％ is …， but …
对应材料例子：
The programme says that about 97％ of the water on Earth is
salt water， so a lot of water is not drinkable.
It mentions that only around 3％ is fresh water， and most of
that is ice.
In fact， just about half a per cent of all water is usable drinking
water.
三、解释水资源的重要性。(结合节目内容)
句式参考：
Water is key to our bodies because …
Water is important because …
It’s important to do sth. since …
对应材料例子：
Water is key to our bodies because humans can only live a few
days without water.
Water is important because because our bodies are about 60％
water—that’s why we need to drink enough water！
It’s important to save water since in many places clean water is
hard to find.
四、互动追问。(和他人交流)
What do you think is the easiest way to save water？ Like
turning off the tap while brushing teeth？
Do you agree that having a quick shower is much better than a
bath？
How do you think we can help people in places with little clean
water？
