D. Water protection
Dear friends,
Clean water is limited. The more people use it, the dirtier it becomes. I suggest we act now to protect water at school.
It's easy to start small — turn off the tap while soaping our hands, use rainwater for plants, and tell the teacher when we find something wrong with a tap.

We should also spread the ideas to everyone. We can put up signs, start river clean-up groups, or show videos to raise awareness of water protection.
Water is nature’s gift. Together, we can save it for now and the future. Be a water hero!

Read Lu Yao's proposal. How many water tips can you find in it Underline them.
Those tips are arranged in parallel structures.
Like: ..., ... and .../ ..., or ...
not only ..., but also ...
Teen skills: Writing parallel structures
Using the same grammatical form for two or more expressions
in a sentence makes a parallel structure.
The structure is used to list information or ideas of
equal importance.
e.g. I like swimming and diving; my father likes fishing and boating.
We use water everywhere—at home,on the farm and in factories.
Floods are dangerous.They may take lives,sweep things away and destroy buildings.

Dear friends,
Freshwater is a precious resource that is often overlooked until it becomes scarce. As inhabitants of Shanghai, a city facing its own set of environmental challenges, we must recognize the importance of conserving water and taking action to protect this vital resource in our daily lives and beyond the confines of our homes.
SAMPLE
Write your own proposal
At school, simple actions can make a big difference. We should be mindful to turn off the tap, ensuring that water is not left running unnecessarily. Encouraging the use of water-saving devices in restrooms and promoting the collection of rainwater for non-potable uses, such as flushing toilets or watering school gardens, are practical steps we can take. Additionally, reporting leaks promptly to school authorities demonstrates responsibility and helps prevent water waste.
SAMPLE
Write your own proposal
Our efforts shouldn’t stop at school grounds. In our communities, there are numerous ways we can contribute to water conservation. For instance, we can advocate for the use of public transportation or cycling instead of driving, reducing the strain on water resources used in car manufacturing and maintenance. We can also participate in community clean-up drives along rivers and lakes, removing litter that contaminates water sources and harms aquatic life.
SAMPLE
Remember, water is not just a commodity; it is the lifeblood of our environment and essential for all living beings. By adopting these practices, we become guardians of this finite resource, ensuring its availability for generations to come. Every small act adds up, and together, we have the power to make a significant difference.
Be a water warrior!

New ways to supply water

Cloud seeding
Cloud seeding is a method of using special chemicals to make clouds rain. At present, over 50 countries in the world, including China, Australia, India and South Africa, use cloud seeding to increase rainfall in their dry regions.

The South-North Water Transfer Project
The project started in 2002, and transports water over 1,000 km from the Yangtze River basin to the Yellow River basin. It has helped to improve the water supply in northern China for homes, farming and industry.

Discovery
The Iceberg Project
In 2017, an Emirati company announced plans to bring icebergs from Antarctica to countries around the world to provide them with fresh water. The company is still working on ways to reduce the cost and keep the ice frozen. If successful, the project will save millions of lives.

Think and discuss
Which method do you like best Why
I prefer ‘Cloud seeding’ best. Because it uses special tech to make clouds release rain. It's great because it can quickly help when there’s no rain, filling up lakes and helping farmers. This method is fast and doesn’t need big builds, making it a good quick fix for dry areas.
----- Linda
Think and discuss
Which method do you like best Why
I think ‘The South-North Water Transfer Project’ is the best. Because it brings water from the wet south to the dry north. It’s super helpful as it gives lots of people in the north a steady water supply. This project supports growth and makes life better by sharing water from where there’s lots to where there’s not enough. ----- William
Think and discuss
Which method do you like best Why
In my opinion, getting water from icebergs means using freshwater from polar regions. Icebergs have lots of clean water. If we move them to places that need water, they can give a big amount of safe drinking water. As icebergs change due to global warming, using them wisely could be a new way to get extra water for some parts of the world.

E. Our water use in a day
Prepare some bottles of water. Make sure you know the amount in each bottle (e.g. 5L, 550ml).
Project
Step 1: Prepare
Use water only from your bottles if possible. Take notes when you use water not from your bottles.
Project
Step 2: Record
6:40 flush the toilet
12:00 refill the 5L (litres) bottles
20:45 take a shower
Add up all the water you used in a day. DON’T FORGET the
water not from your bottles.
Project
Step 3: Add up
You can search the internet for the information you need.
For example:
How much water does a shower take
Since the average length of a shower is just over 8 minutes, around 20 gallons of water are used for each shower.
However, some people enjoy taking longer showers, which can significantly increase the amount of water used.
Shorter showers and more efficient showerheads can offer a similar experience while reducing the amount of water used.
Project
How much water does a shower take
What information to include in your group presentation.
e.g.
How much water does everyone in our group use on average
Would you use water differently if you had to walk for hours to fetch water every day
Project
Step 4: Discuss
Give a group presentation to share your findings and ideas.
Project
Step 5: Present
Hello everyone! Today, let’s talk about how much water we use in a day. I’m here with a group of five boys from our junior high school in Shanghai, and we’ve been tracking our water usage.
Project
Sample
First, let’s start with drinking water. On average, each of us drinks about 1.5 liters of water every day. That’s like filling a small bottle three times. So, for the whole group, we drink about 7.5 liters just for staying hydrated!
Project
Sample
Next up is taking showers. Showers can use a lot of water! Each boy uses around 20 liters for a shower. Imagine that --- 20 liters is like filling a big bucket four times! For all five of us, that’s 100 liters of water going down the drain every time we wash up.
Project
Sample
Now, let’s talk about washing hands. Every time we wash our hands, we use about 2 liters of water. If each of us washes our hands five times a day (which is pretty normal), that’s 10 liters per person. For the group, that adds up to 50 liters just for clean hands!
Project
Sample
And what about doing laundry Washing clothes also takes a good amount of water. Each load of laundry uses about 50 liters. If we do laundry once a week, that’s still about 7 liters per day when you spread it out. For all of us, that’s another 35 liters.
Project
Sample
Putting it all together, each boy uses roughly 40 liters of water in a day for these activities. So, for our group of five, we use about 200 liters of water every day!
That’s a lot, right And remember, this is just for the basics—there are many other things we do that use water too.
Project
Sample
So, next time you turn on the tap, think about how much water you’re really using. Let’s all try to be more mindful and save water where we can!
Thanks for listening!
Project
Sample
Listen to other groups’ presentations. Which do you like best What have you learned
Project
This presentation really opened my eyes to how much water we use every day, even for simple things like drinking and washing. I learned that small actions, like turning off the tap while soaping up, can add up to big savings. It’s amazing how much water five people go through in a day --- 200 liters! Now, I want to be more careful and not waste water. Every drop counts!
