阅读材料,然后从各小题所给的四个选项中选出最佳选项。
        Many places in the world need 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 is not hot enough. Or it
does not shine every day. 
        In such 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 bits of ice are taken out. Which way is the best? The one 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 does not make very much water at a time. But the
factory is easy to build and costs little. That is why people in many dry places talk about Symi!
