Salt water into fresh

Salt water into fresh
阅读短文回答问题
The little island of Symi had a big party not long ago.Everyone sang and danced in the streets.Bells rang.Flags were high.What was it about?
For the first time,this island of Greee had its own fresh water.Women could fill their pails with all the water they wanted!
Very little rain falls on Symi.The people have always saved every drop they could.But it has never been enough for their needs.They have had to buy water brought by ships.
Now Symi has its own"water factory".The factory changes salt water from the sea into fresh water that people can drink.
Most of the ways to turn salt water into fresh water cost a lot of money.The Symi factory uses a way that costs very little.
What is the factory like?How does it work?Right in the middle of the town are some long water pools.They are only a few inches deep.The men of Symi dug out earth to make these pools.
Over each pool is a low tent.It is made of plastic that you can see through.
At night,sea water is let into the pools.The next day,the hot sun shines through the tents.The sun'sheat turns water into vapor that rises from the pools.The salt is left behind.Then the vapor becomes big water drops.They run down the sides of the tent and fill a tank with fresh water.
The salt is washed out each night.Then more sea water comes into the pools.The factory is ready for next day's work.Sea water and sun cost nothing.Most people in Symi are poor,so to them this new way of getting fresh water seems wonderful!
