Trees are one of the oldest "citizens (公民)" of our Earth. They keep our air clean, reduce noise pollution, improve water quality 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.

When trees are 4 years old, they begin to grow very quickly and become strong enough to face challenges(挑战). 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. The adult tree gives us shade, oxygen(氧气)and natural beauty; it is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live for many years.

Gradually, trees begin to grow older and older and even die. At this time, they still have the 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(来源) of food for many other 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 about that each period(时期) of life brings its own joy and challenge. Enjoy every minute of the life of the trees and take care of the trees!

Many students felt it difficult to remember new words when they begin to study English. Now I will give you some advice.

English words. How do you learn to speak Chinese? You did it by listening carefully to the people talking to each other.
