年少懵懂的日子我们总是不会珍惜时光，等到我们都不再年轻，才发现，青春美好的日子，是那么珍贵。

　　“燕子去了，有再来的时候;桃花谢了，有再开的时候;杨柳枯了，有再青的时候;可是亲爱的，为什么我们的日子一去不复返了呢?”朱自清用一段排比来描述了青春日子是这样的匆匆离去。一路走来，我们总会仰天长啸：啊，青春，回来吧!殊不知，青春已走远，再也回不来了......

　　It was New Year's night. An aged man was standing at a window. He raised his mournful eyes towards the deep blue sky, where the stars were floating like white lilies on the surface of a clear calm lake. When he cast them on the earth, where few more hopeless people than himself now moved towards their certain goal—the tomb. He had already passed sixty of the stages leading to it, and he had brought from his journey nothing but errors and remorse. Now his health was poor, his mind vacant, his heart sorrowful, and his old age short of comforts.

　　The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads--one leading to a peaceful,sunny place, covered with flowers, fruits and resounding with soft, sweet songs;the other leading to a deep , dark cave, which was endless, where poison flowed instead of water and where devils and poisonous snakes hissed and crawled.

　　He looked towards the sky and cried painfully," O, youth, return! O, my father,place me once more at the entrance to life, and I'll choose the better way!" But both his father and the days of his youth had passed away.

　　He saw the lights flowing away in the darkness. These were the days of his wasted life;he saw a star fall from the sky and disappeared, and this was the symbol of himself. His remorse, which was like a sharp arrow, struck deeply into his heart. Then he remembered his friends in his childhood, who entered life together with him. But they had made their way to success and were now honored and happy on this New Year's night.

　　The clock in the high church tower struck and the sound made him remember his parents' early love for him. They had taught him and prayed to God for his good. But he chose the wrong way. With shame and grief he dared no longer to look towards the heaven where his father lived. His darkened eyes were full of tears, and with a despairing effort, he burst out a cry:" Come back, my early days! Come back!"

　　And his youth did return,for all this was only a dream, which he had on New Year's night. He was still young though his faults were real; he had not yet entered the deep, dark cave, and he was still free to walk on the road which leads to the peaceful and sunny land.

　　Those who still linger on the entrance of life, hesitating to choose the bright road, remember that when years are passed and your feet stumble on the dark mountains, you will cry bitterly, but in vain. "O youth, return! Oh give me back my early days!"
