Millions of people around the world cook their food on fire every day. People must spend lots of money on cooking fuel. However, there is a much easier and cheaper way to cook food using energy from the sun.

The second kind of sun-cooker is a panel cooker. It has several flat walls that concentrate the sun-shine on the food. People can build panel cookers quickly. They do not cost much. In Kenya, for example, panel cookers cost just two dollars.
The third kind of sun-cooker is a parabolic cooker. It has rounded walls that concentrate sunlight into the bottom of the cooker. Food cooks quickly in parabolic cookers. However, these cookers are hard to make. They must be moved again and again to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make sun-cookers from boxes or heavy paper. They will not catch fire. Paper burns at 232℃. A sun-cooker never gets hotter than that. Sun-cookers cook food at low temperatures over long periods of time. This allows people to cook food and do other things at the same time.

A man was walking along the street when he saw a woman carrying a large box. It was half in and half out of her car. So the man went up and said, “The box looks very heavy. Let me give you a hand.”

“That’s very kind of you,” the woman said, “I’m having a lot of trouble with it. Maybe it sticks (卡住) in the car door.”

“Together we’ll soon move it,” the man said. “I’ll get in and take the other end.” And he got in the car.

“Right,” the man said. “I’m ready,” and he began to push the box hard.

For several minutes, the man and the woman tried to move the box. Soon they felt very tired.

They rested for a moment. Then the woman said, “Let’s try again. One, two, three!” They went on moving the box.
