Plants and animals are largely made of water． So are humans． They need to keep enough water inside them， or they could die．

We get some of the water we need by eating food that has water in it． Drinks， such as milk and tea， are mostly water， too． A person needs water every day． If we go without water for three or four days，we will lose too much water from our bodies．In very hot weather，we could lose this water in just one day．

What does water do to help our bodies？ Water helps to take the nutrition（营养）from food to our bodies． It also helps to take the wastes away from different parts of our bodies．

In our homes， we also need water for many things． We need water for cooking， washing and flushing（冲水）the toilet． About three quarters of the water is used in the bathroom and toilet． The rest is mainly used in the laundry（洗衣房）and kitchen．

 _______It may come from a lake or a river． It may come from the sea， from the rain and snow or from the underground． Water rises from rivers and seas to make clouds， and then falls again as rain and snow． The water you drink has been around for millions of years． It just keeps being recycled．

Many people work hard to make sure we always have clean water in our homes． Water is very important for all living things， so we should use it carefully．
