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, water and sunlight. Animals and men can't make food from air, water and
sunlight. Animals get their food by eating plants and other animals. Therefore, animals and men need plants
in order to live. This is the reason why we find so many plants around us.
If you look carefully at the plants around you, you will find that there are many kinds of plants. Some
plants are large while others are small. Most plants are green.
Some plants have many small leaves. Others have only a few. There are many kinds of leaves. Leaves
are of different shapes and colors.
Leaves are also different in other ways. Some leaves have long thin parts at the end, we call them leaf
stalks, some have short leaf stalks, others even have no leaf stalks. The leaf edges are also different. Some
leaves have smooth (平滑) edges. Some have wave-shaped edges. Others have edges like the teeth of
a saw. (鋸子)
