Let's take a minute to think about the water we use. The human body is 60% water and we need to drink lots of water to be healthy. When we are thirsty we just go to the kitchen and fill a glass with clean water.
1.For example, farmers, who produce the food we eat, use water to make the plants grow. When we turn on a light or switch on a TV or a computer we use energy and we need water to produce this energy.
The truth is that we are lucky enough to have clean water whenever we want，but this is not the case for many people around the world.2.That's around one in 10 people in the world. If we drink dirty water，we can catch diseases from the bacteria and become ill. Every year over 500，000 children die from diarrhea(腹泻)from dirty water. That's around 1，400 children every day！Also，in some countries children walk many kilometres every day to get water.3.Therefore，they don't have time to learn how to read or write and don't get an education.
4.On this day every year，countries around the world hold events to educate people about the problems of dirty water and that clean water is something that everyone should have around the world. At one school in the UK，children between the ages of 10 and 15 walk 6km with six litres of water.5.People give them money to do this and all the money helps get clean water to as many people as possible around the world.
A.We use water indirectly too.
B.Every system in our body depends on water to function.
C.It is to inspire people to learn more about water-related problems
D.If children walk many hours a day to get water，they can't go to school.
E.Did you know that around 750 million people do not have clean water to drink？
F.In 1993 the United Nations decided that March 22nd is the World Day for Water.
G.In this way，they know how it feels to walk a long distance carrying heavy bottles.
