no creature can live without water and human being is not an exemption as well. our body is mainly formed by water, about 70% or more. so everyday we need to drink a lot to keep ourselves healthy and full of energy. except that, there are lots of things we need water in our daily life. we need to use water to cook, to wash clothes, to shower and so on. as we know the water shortage is a big issue all over the world. therefore save water is very important in our life.。

how to save water
water is very important in our life. we drink it every day and use it to cook and wash things. we can not live without water. but how can we save water?
there are several ways to save water. firstly, take shorter showers and don't leave the tap running when we don't need to use water. secondly, try to reuse water . it's the most important way for us to save water. at last, we should not pollute water so that we willl have fresh water for years and years.
if we do not save water, the last drop of water will be a teardrop. to protect water is to protect our life.
.some people think there's much water on the earth.in fact,there is only a little water for us to use now.if we don't save it,it will surely be used out some day.
then what should we do?
first,when we finish washing the clothes,we can use the water to clean the floor.second,if we see the dripping tap,we ought to fix the tap as soon as possible.third,we can have a shower instead of a bath because having a bath can waste a lot of water.
in these ways,we can save not only huge amounts of water but also ourselves
the water preservation
knowing about the fact that we are in a serious condition with poor capacity of water,what will we do?
every day,lot's of water is waisted by people in the factories and dormitories of school.we should stop this bad action,and preserve the water.when we see the water running out of the tap,we should turn it off.when we see someone is waisting the water,we should walk to him or her and stop this action.we should decrease the amount of water to be used,and tell everybody to protect the water.try our best to make everyone at school know that water is so important that it must be protect well.that's what we should do.
the world is not only hungry,but also thirsty for water. this may seem strange to you, since nearly 75 % of the earth's surface is covered with water. but about 97% of this huge amount is sea water, or salt water. man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. and we cannot even use all of that, because some of it is in the form of icebergs and glaciers. even worse, some of it has been polluted.
however, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. but our need for water is increasing rapidly-- almost day by day. only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. a limited water supply would have a bad effect on agriculture and industry. let me give you just one small exampie of how necessary water is to industry. did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?
we all have to learn how to stop wasting our precious water. one of the first steps we should take is to develop ways of reusing it. experiments have already been done in this field, but only on a small scale. for us, the systems are as important as the spacecraft.

it'snice to say that we can do for our school and i think each of us cando something. the first thing i can do is to make our school more beautiful by plantingtrees in the school, or organizing a thorough cleaning on the school. we canalso form a good habit of putting the rubbish in the trashcan. the second thingwe can do is to protect the things in our school. when we leave theclassroom, we should never forget to turn off the light or close the door.don't leave the tap water running or waste any materials in the class. everyone including me , must save everything we use.。
