Trees are one of the oldest "citizens (公民)" of our Earth. They keep our air clean, reduce noise pollution,
improve water quality (質(zhì)量) and provide food and building materials.
Just like us, trees change a lot as they grow. At l 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.
當(dāng)小樹成長到四歲的時候,它們成長開始加速并且變得足夠強壯以面對未來生命中的挑戰(zhàn)。 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 shade, oxygen (氧氣) and natural beauty; it is also a great place for a tree
house, or a place for us to nap, read a book, listen to music or sip.(小口喝) tea. If we give the adult tree
proper care, it will continue to live healthily for many years.
Gradually (漸漸地), 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 to small animals' and is a source of food for many other animals.
In many ways, the life of a tree is similar (相似的) to our own life experience. When we are looking at the
life of a tree, we learn about that each period of life brings its own form of joy and challenge. Enjoy every
minute of the life of the trees and take care of the trees!
