雪花飘呀飘,飘到了你的头上。就被误认为是头皮屑呢!雪还可以堆雪人,红红的鼻子,黑黑的眼睛真是可爱极了。大家可以来打雪仗,可以望着大雪纷飞、苍白的大地,显示它的美。
可是,有一首古诗是这样的:尽道丰年瑞,丰年事若何?长安有贫者,为瑞不宜多。是呀,在旧社会上还有这样的人啊。他们忍饥挨饿,连吃口饭都难。在这样的冰天雪地里,把庄稼都压着,岂不是不能维持生活了吗?那单薄的衣服,让他们就这一点一点的冻死,又能怎么办呢?
还有七老八十的老奶奶,看不见光明的盲人。又该怎么扫门前的雪呢?雪有它的好处,自然就有它的灾害。我希望全世界的'人们在下一次雪的来临时都应该是高兴的。
没有了忍饥挨饿的人了,只有那高高兴兴在雪地里玩耍的孩子。雪,其实就是这样奇怪的。
Everyone may encounter a scene when he or she wonders what the meaning and purpose of life is. Answers to this question vary from person to person. As for me, I agree with the view that the meaning of life is to discover your gift and the purpose of life is to make the best of it.
On one hand, one's gift could be the source of his inner happiness, providing spiritual impetus and correct orientation. Take the world-renowned Chinese pianist Lang Lang as an example. His gift was noticed before he was 3 years old, which laid the foundation of his glorious life. On the other hand, proper use of talent helps people to realize their value in a positive way, thus making contribution to the society as a whole. For instance, Isaac Newton made a universally amazing discovery by digging into his gift and finding the Newton's law of gravitation.
In conclusion, let's search for our true gift and utilize it to the fullest to achieve a happy and valuable life.
