I have been exposed to the heat in summer, and I am always annoyed; Autumn in the north always indicates the arrival of winter. When you are upset, it will make people feel a little cold, but it will also make people calm. As time goes by, autumn in the north comes again. The girl sat there quietly, her arm leaning on the desk full of knife marks and handwriting; There is a clean and open physics book on the desk. The teacher stood on the podium, beaming at all kinds of theorems and laws, but his heart had already left the classroom. The girl looked out of the window, looking at everything she could see and thinking about everything she could think of. Her eyes swept past the office buildings, across a wheat yellow grass, and then she locked a tree that should not be towering. This tree is still tall and straight by the ruthless autumn wind; Its leaves are densely arranged, unlike other trees at all. At this moment, suddenly a green leaf, after breaking free from the shackles of the big tree, danced happily in the air, smiled freely and heartily at all its companions and landed on the girl's desk. The girl stared at the leaves ... "Haha, I'm free at last! I am finally free! " Leaves can not help but whisper, "after endless efforts, I succeeded!" " "Just as the leaves were triumphant, the words of the desk interrupted the pride of the leaves:" I, a desk, was originally a weak and fragile wood, but after countless processing procedures and numerous tempering, I finally got such a hard quality ... ""Is it too much trouble? It takes too much time! Why not be as free as my leaves, just by transforming myself? Don't you want freedom? You should envy me! In addition, hard quality is of little use to me. " The desk primly said, "you, you ... I want to have hard quality;" Only hard quality can overcome all difficulties ... You ... I also wanted to be free in the past and continue to be regarded as a tree. How nice it would be! ..... but what about you? Freedom is not enough; It won't be long before you get rid of a little difficulty. " Hearing this, Ye Zi was very angry and wanted to shout at the table. Just as it was about to do that, a cold autumn wind suddenly blew over, turning its face into red leaves and blowing it up and down-I don't know what the West is. The autumn wind was mixed with a trace of sadness, spinning the poor leaves, and finally along the gap of the sewer, it was thrown into the muddy water filled with rancid smell ... The girl understood something. She gradually turned her head back, gradually turned her eyes to the textbook, and gradually pulled her ears, which had been immersed in the bleak outside the window, back to the warm classroom, listening to the teacher and writing.
