Many places in the world need more fresh (淡的）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 (煮沸）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 (冷冻). 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 be built and doesn’t cost a lot!

That’s why people in many dry places talk about Symi!

Every school day, we use schoolbags to carry all of our things to school. They are a big part of our lives. But have you ever thought about the history of the schoolbag?

In the Han Dynasty (汉朝), students in old-style private schools used bamboo boxes to carry books to school. People consider the bamboo boxes to be the earliest schoolbags. They were usually two or three layers (层) in the box. Kids put different things like books, brushes, ink stones (砚) and paper in the boxes.

Hundreds of years later, people developed a new kind of schoolbag called the budai, or the "hip-pocket". The budai was lighter than the bamboo box. With the founding (成立) of the People's Republic of China, military rucksacks (军用帆布包) became popular. Many people carried them when they were in school. Ask your grandparents or parents about these bags. Maybe they can tell you about their experiences of carrying them when they were in school.

A new style of schoolbags has appeared in recent years. Many of them have colorful and fashionable designs (时尚的设计) on them, such as pictures of cartoons or pop stars. And they are more comfortable to use. Some students pull wheeled bags filled with heavy textbooks and others carry backpacks.
