Trees are everywhere around us. They provide us with many useful things.
Before trees become helpful, they change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.
It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. Not only does the adult tree give us natural beauty, but it also cleans up dirt and fights flood. If we give the adult tree proper care, it will continue to live healthily for many years.
| Trees grow in many different places, so they have developed special ways to help themselves live. ●In deserts, trees need to hold on to water. The tree saves water in its trunk. ●In the highlands, trees grow very close to protect them from the strong winds. ●In the rainforests, trees grow up to fifty meters tall to get more sunlight. |
Gradually trees begin to grow older and older and even die. At this time they still have their important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it provides a home for small animals.
In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge.
Enjoy every minute of our life and take care of the trees!
