　　World Water Day
　　Did you know that about 2.1 billion people have no safe drinking water？
World Water Day aims to solve this for most people in towns and cities by
2030.
　　What is World Water Day？
A
　　On 18 January， 1993， the United Nations designated（指定） 22
March as World Water Day.It draws our attention to the importance of water
across the world and calls on us to protect water resources.
　　Valuing water
　　The theme（主题）of World Water Day changes yearly.In 2025， the
theme is“Glacier Preservation（冰川保护）”.By celebrating this festival
and learning about how water will benefit our lives， we can learn to value
water properly and work to make sure that everyone has clean water to drink
and use.
　　Every water drop counts（重要）
　　Water is very important to all living things because without it，
humans， animals and plants would die.For example， we need water to
drink and keep our bodies， clothes and other things clean.All trees and other
plants need water to live and grow as well.
　　We are lucky that in our country we can go to a tap and get clean and
fresh water to use.However， not everyone is able to do this.In some other
countries， people may have to walk miles to the river to collect water which
isn’t even safe to drink.It is important that we all make sure we do not waste
the water we have.
（　B　）1.According to the passage， what will happen in about five
years？
A. Most people will have tap water.
B. Most people in towns and cities will have safe drinking water.

　　The world uses about a thousand million tons of water a day.Water is a
human right and everyone should have their share.Yet more than 700 million
people around the world have trouble getting clean， safe water.
　　Treating（处理） wastewater is a good way to provide fresh water for
us.And it also helps the environment by keeping waste out of rivers and
oceans.80％ of wastewater around the world is not treated at all， and it is
running into oceans.But now we have got the technology to treat and reuse the
wastewater.
B
　　While 75％ of our planet is covered with water， only about 2％ is fresh
water—that comes from rivers， lakes， ice and snow.The rest， 98％ of the
water， is in seas and oceans.It is too salty to drink.Then desalination（海水
淡化） businesses come in.More than 19，000 factories have been built
around the world， mostly in coastal countries.They process（加工） more
than 92 million tons of water every day.But the technology needs a lot of
energy.
　　Scientists are working to create a less costly technology.They want to
produce 20 times more clean water and make sure everyone has enough.But
for now， the world still faces with not having enough water for everyone each
day.
（　D　）6.How many people have trouble in getting clean water around the
world？

school， dripping taps waste 20 litres daily－enough for a child’s drinking
water for a week！
To save water， here’s what you can do：






　　Thank you！
First，always turn off taps firmly； second，collect rainwater for plants；third， report broken pipes.
Remember： Every drop counts.You have the power to change the world！
Every time you save a drop of water， you’re giving someone else a future.Let’s be the generation that turns the tide！When we save water， we save the
