在冬天去看望我叔叔之前，我从来没有见过雪。下雪的时候，首先，天空中满是白色的东西掉落在地上

Before I come to visit my uncle in the winter, I never see snow in my life. When it snows, the sky is full of white things that falling into the ground first, I feel so excited about this scenery. As the snow comes heavy, I can play snow with my cousins. We make the snowman and decorate it with funny facial expression. 
在冬天去看望我叔叔之前，我从来没有见过雪。下雪的时候，首先，天空中满是白色的东西掉落在地上，我对这景色感到很兴奋。大雪来临时，我可以和我的表兄弟们一起玩雪。我们堆雪人，用有趣的面部表情来装饰它。
