①Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh.
Why aren't there many factories like the Symi factory?
In some places, the sun isn't hot enough, or it doesn't shine every day. In these places, other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat. A lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.One way is freezing. The fresh part of salt water freezes first. To get fresh water, the pieces of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way for each place.
Symi's way seems very good for small, hot places. It doesn't make very much water at a time. But the factory is easy to build and cost little.
②That is why people in many dry places talk about symi!

One day Bob took two of his friends into the mountains. They put up their tents and then rode off to a forest to see how the trees were growing.
In the afternoon when they were about ten kilometres from their camp(营地), it started to snow. More and more snow fell. Soon Bob could hardly see his hands before his face. He could not find the road. Bob knew there were two roads.
One road went to the camp, and the other went to his house. But all was white snow. Everything was the same. How could he take his friends back to the camp?
Bob had an idea. The horses! Let the horses take them back! But what would happen if the horses took the road to his house? That would be a trip of thirty-five kilometres in such cold weather!
It was getting late. They rode on and on. At last the horses stopped. Where were they? None of them could tell. John looked around. What was that under the tree? It was one of their tents!
