What Are Materials
Stone, metal, wood, paper, and cloth are materials. We use them every day.
Stone is a hard, heavy material. Most stones sink to the bottom of water. We get stone from the ground and from mountains. Stone does not bend, but it can be cut into shapes.
We get metal from stone. Metals are strong and difficult to break. They are usually shiny. Metals are hard like stone, but we can bend them and make them into different shapes.
Can you read and write
Wood is a material from trees. Wood is a hard material, but it is not as hard as stone or metal. We can cut and shape wood with metal tools.
Paper is a soft material from plants. It is light and very easy to bend and fold.
Cloth is a soft material. There are different kinds of cloth. We make cloth from sheep's wool, cotton, and silk. We use cloth to make many things such as T-shirts and jeans.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, sunlight and water. Man and animals cannot make food from air, sunlight and water. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live.
There are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of (例子) a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽).
