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 not only gives us shade, oxygen and natural beauty, but also provides a great place for us to rest, read books or listen to music. After that, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When part of a tree becomes dead, it provides a home for small animals.

One day, the spider caught a little bug in her web. Just as the spider was about to eat him, the bug said, “If you let me go, I will tell you something important that can save your life.”
The spider thought for a little while and listened. “You’d better get out of this cornfield.” the little bug said, “The harvest is coming!”
“I think you are just telling me a story.” the spider said with a smile.
“Oh no, it is true.” the little bug said, “All the stalks(杆) will be knocked down, and the corn will be gathered up. You will be killed by the great machines if you stay here.”
“I don’t believe you.” the spider said as she ate the little bug for lunch.
A few days later, the spider was laughing about the story the little bug had told her. She thought to herself. “A harvest! What a silly idea! I have lived here all of my life, and nothing has ever disturbed(打扰) me.”
The next day was a beautiful sunny day. The sky above was clear, and there was no wind at all. That afternoon, as the spider was about to take a nap(小睡), she noticed some thick dusty clouds moving towards her.

Trees are important in our daily lives. What are the parts of a tree
Seeds
Like many plants, a tree begins from a seed. A seed must have food, water and sunlight to grow.
Roots
All of the trees have roots. They go into the soil and have two important jobs to do: they make the tree stand, and they take in water and other things from the soil.
Trunks
The trunk of a tree supports (支撑) the branches of the tree and moves water and other things from the soil to the other parts of the tree.
Branches
Branches grow out from the trunk. They are the growing ends of the tree. They also move water and other things from the trunk to the leaves.
Leaves
Leaves can catch sunlight. Using sunlight, the leaves produce food for the whole tree. Leaves use the water from the soil to make sugar to feed the tree. At the same time, trees release (释放) oxygen into the air. This is very important, because all the animals and humans need oxygen to live.
