下雪了。在那年元旦，我还在家乡的小城里苦读高三。因为离家较远，元旦的假期时间又短，我只好独自蜷缩在宿舍的一隅。空旷的宿舍，是那样的宁静。透过冷冰冰的窗子，凝望着窗外满世界飞舞的雪花，心中涌动着无限的酸楚和惆怅。

老鼠们准备过一个快乐的元旦，就在这时，一件让人说不出是什么感受的事情发生了。这不，天气越来越冷，老鼠哥哥穿上了小鼠奶奶给做的棉袄，老鼠妹妹也有一件，可是爱美之鼠怎会穿棉袄呢?老鼠哥哥可不爱美，只要能有穿的就行呗，哪里还管...

伴着祥云朵朵，我们送走了XX，送走了旧日烦恼，迎来了新的一年，新的风光。XX年的第一天元旦，已悄然来临。起床了!起床了!妈妈大声的叫喊着，好事就九天之上的雷霆，轰隆隆!真是如雷贯耳!

我把一束鲜花工工整整地放在自己的胸前，慢慢地走到了演员的身前。献花的我本应该离演员一定距离，走近时要先向演员行队礼，再把花递上去，转身回来前要先退后两步。元旦的晚上，蔡老师带我去电影院听新年音乐会。

今天不知怎么的，乍往街上一看，到处都是红红火火的，张灯结彩，令我实在是纳闷儿，今儿个是什么日子，值得人类这样高兴?不管了，反正是好日子，就出去逛逛吧，反正会有好东西的!

Today, as the development of the medical, people can slow down their aging. As for the celebrities, they use the developed technology to keep young, seeing their unchangeable faces in the screen for so many years, the audience also want to imitate the celebrity, they believe that by using the developed technology, they can keep young all the time. While in my opinion, the way to keep young is to hold a young heart, some people look young outside, but in their hearts, they are old enough and refuse to keep pace with the time. While for another group, even they have wrinkles, they are curious about all the things and are willing to change. My grandpa is old, but he knows all the fashionable things, sometimes I have to ask him for the new things. The young heart is the way to keep young forever.

今天，随着医疗的发展，人们能够延缓衰老。对于名人来讲，他们使用高科技来保持年轻，看到他们常年在屏幕上保持不变的容颜，观众也想要模仿名人，他们相信通过使用高科技就能一直保持年轻。然而在我看来，保持年轻的方法就是拥有一颗年轻的心，一些人表面看起来年轻，但是在他们的心里，他们足够的老，并且拒绝去与时俱进。对于另外一些人来讲，虽然他们有皱纹，但是他们对一切都保持好奇，并且愿意去改变。我的爷爷年纪大，但是他对一切时尚的东西都了如指掌，有时候我不得不问他关于新的事物。年轻的心是永葆青春的方法。
