洁白的雪花从空中飘落下来，给大地披上了一层雪白的衣裳，一些动物正在悠闲的冬眠，世界变得安静下来。
The white snowflakes fall from the air, covering the earth with a layer of white clothes. Some animals are hibernating leisurely, and the world becomes quiet.
教室中的我们，正上着有趣的科学课，窗外那美丽的梅花，暗暗散发着芳香。老师拿起自己手中的烧杯，好像在琢磨着什么。过了一会儿，老师又将试管举起，我们都很好奇，这是要干什么呢？只见他将试管中紫色的溶液倒入了烧杯中，轻轻地晃了几下，神奇的事情发生了，溶液从紫色变成看蓝色，这又是为什么呢？大家正在疑惑不解的时候，老师让我们自己来做一做这个实验，我们既好奇又兴奋，二话不说，就拿起器材做实验，可是，面对眼前这不解的现象，又担心奇迹会不会在自己的手中出现，心中像装了十五只吊桶七上八下。
In the classroom, we are having an interesting science class. The beautiful plum blossom outside the window exudes fragrance. The teacher picked up the beaker in his hand as if he was thinking about something. After a while, the teacher raised the test tube again. We were all curious. What is this? He poured the purple solution in the test tube into the beaker and shook it gently for a few times. Something magical happened. The solution changed from purple to blue. Why? When we were puzzled, the teacher asked us to do the experiment ourselves. We were curious and excited. Without saying anything, we picked up the equipment to do the experiment. However, in the face of the puzzled phenomenon, we were worried about whether the miracle would appear in our own hands. In our mind, there were 15 buckets.
我拿着盛放液体的瓶子看了一眼，无非就是颜色有点特别，并没有什么异常的现象，拿起瓶子摇了摇，瓶中除了有些杂音之外，没有任何异样。“难道是这种物质在空气中发生了反应？”我在心中揣测着，思考了很久，但是一点头绪也没有，坐在我旁边的同学静静地看着我，眼里充满着期待。这时，科学老师走到我身边并告诉我说：“这种液体在高速运动中，会发生变色现象。”我似乎想出了一些原理，试着将溶液放在酒精灯上燃烧，可一点现象也没有；我又陷入了沉思，大家都在目不转睛地看着我，仿佛是在说：这回你得出丑了，等会让我们看你垂头哭脸的窘态。我的倔劲在胸中燃烧：我偏不信连这小实验也做不了！我冷静下来，沉思片刻，终于有了头绪。
I took a look at the bottle containing liquid. It was just that the color was a little special and there was no abnormal phenomenon. I picked up the bottle and shook it. Except for some noise, there was nothing different in the bottle. "Did this substance react in the air?" I speculated in my heart and thought for a long time, but I didn't have a nodding thread. The students sitting next to me looked at me quietly, and their eyes were full of expectation. At this time, the science teacher came to me and told me, "this liquid will change color in high-speed movement." I seem to have come up with some principles, trying to put the solution on the alcohol lamp to burn, but there is no phenomenon at all; I fell into meditation again, and everyone was staring at me, as if to say: this time you have to make a fool of yourself, and we will see your embarrassment of drooping and crying. My stubbornness burns in my heart: I don't believe that I can't even do this little experiment! I calmed down, pondered for a moment, and finally got a clue.
我将烧杯加热，并在加热的过程中向里面注入空气，慢慢地发现溶液终于由紫色泛出了蓝色，内心的欢喜难以言表，我的方法是对的；我继续加热，不再畏惧时间的延续，通过老师的帮助，我终于将紫溶液变成了蓝溶液。教室里传出了一阵热烈的掌声，我感到十分的欣慰，我为我自己的实验成功感到无比地兴奋。可能这就是做实验的乐趣吧！
I heated the beaker and injected air into it during the heating process, and slowly found that the solution finally turned from purple to blue. My joy was beyond words, and my method was right. I continued to heat, not afraid of the extension of time. With the help of the teacher, I finally turned the purple solution into the blue solution. There was a burst of warm applause in the classroom. I was very pleased. I was very excited about the success of my own experiment. Maybe that's the fun of doing experiments!
岁月如此悠长，学习也在不断地进行中，既有快乐也有忧伤，这次的科学课让我明白了，只有通过自己不懈努力，不断实践，事情才有可能做成功。
With such a long history and continuous learning, there are both happiness and sadness. This science lesson taught me that only through unremitting efforts and continuous practice can things succeed.
