Reading Title: Fallen Leaves

Outside the window, there was a small tree. In the spring, it was full of leaves. The roots of the branches were dark green, and the tips of the branches were light green. Although they were born in pairs, each piece was different from the other, and their postures were also different. When there was no wind, she looked plump, delicate, and dignified. In the morning and evening wind, the leaves would move. Under the backdrop of the sky, the green veins on the back of the leaves could be seen, like countless colorful butterflies falling there, dancing, and like a young woman, graceful and charming, making a charming smile. I often sit in the window and look at it, feeling gentle and beautiful. I am even very jealous of the couple of birds living among the branches. They stop under the leaves and sing. Is it they who bring joy to the tree, or is it the joy of the green that makes their songs clear and wonderful? The joy of Fatong would last for a whole summer. I always thought that the leaves that were full of longing would grow up like cattail leaf fans, but in late autumn, the leaves would no longer grow, but would fall one by one. Fa Tong became thinner and more shabby. It became naked, with only a few bones. Moreover, they were stiff and no longer soft and graceful. With a fold of his hand, they broke off piece by piece. I felt that this was very cruel. I deliberately went to pick a fallen leaf from the tree and kept it as a memory of the past. He thought, Poor Fatong, who gave you life and let you grow on the ground like this? Since I gave you this green joy, why did I have to take it away piece by piece? In the spring of the next year, the paulownia tree was full of leaves again. It was still light green or dark green. I took out the fallen leaves that I had collected over the years. Compared to this new leaf, the outline of the leaf was the same. Oh, leaves, do you know each other? Do you know which one is the substitute for this one? Perhaps it would grow from the eye of a leaf stalk, and the fallen would once have been so happy, and the happy would soon wither away in silence. However, they were not sad, and when they were happy, they had to be happy. That was all. The paulownia tree grew bigger and bigger year by year, growing beyond the windowsill and reaching the eaves! I suddenly realized that my lamentation in the past was unnecessary, and it was very childish. It turned out that the growth of the paulownia tree was not only the movement of the green life, but also the verification of a philosophical proposition: Joy comes, joy goes, this is the content of joy between heaven and earth; everything in the world is seeking this content, and each of them completes its existence. So I admired Fattong very much and blessed it: It shed old leaves every year, and thus longed for new life in the coming year. Only then did it not stagnate, nor did it age, but its goal grew into a useful person in heaven and earth. 1. In the second paragraph," I'm even very jealous of the bird couple who live between the branches." Can you tell me why? 2. What did the "this" in the fourth paragraph "I think this is very cruel" refer to? 3. The article used the lyrical technique of expressing one's aspirations through objects, using the withering and growth of the leaves of the tung tree to explain a principle of life. Please use this method to write a paragraph.
