三、阅读理解。
We all know the sun is important. It provides for plants, animals, and people here on Earth. But how does the sun do that? It's the sun's energy that makes life on our planet possible.
Energy from the sun is called solar energy. It comes in the form of light or heat. Solar energy is what makes you feel hot when you sit in the sunlight. People have used solar energy for thousands of years. Houses were built with windows so that sunlight can get inside and provide heat.
The sun's energy can also be used to heat water and even food. If you own a magnifying glass (放大镜), your parents have probably warned you about leaving it in the sun. Solar energy can actually make the magnifying glass burn objects underneath it, causing a fire. This type of energy from the sun in the form of heat is called solar thermal energy.
We can also turn the sun's light into electricity. This is done with solar panels (板). Solar panels are made of a material called silicon (硅). The silicon is heated and formed into very thin slices. When the sunlight hits the solar panel, the electrons in the silicon move and flow through wires built into the solar panel. Using this technology, we can run a calculator and even power cars.
