大千世界，无奇不有。在科学的领域里，奇妙的现象超乎你的想像。下面就让我来给讲讲我的发现吧。
The vast world is full of wonders. In the field of science, wonderful phenomena are beyond your imagination. Now let me tell you about my discovery.
一天，我在削苹果的时候不小心割破了手指，鲜血顿时流了下来。我吓呆了，盯着手指一动也不动，直到疼痛清晰地传来，我才清醒过来。我看见桌上有一杯茶，那是妈妈刚泡好的，我不管三七二十一，把手指放了进去。很奇怪的是，血一下就不流了，手指也不怎么疼了，我当时也没有想太多。
One day, while peeling an apple, I accidentally cut my finger and blood immediately flowed down. I was stunned and stared at my fingers without moving, until the pain came clearly before I woke up. I saw a cup of tea on the table, which my mother had just brewed. I ignored it and put my finger in it. It's strange that the blood stopped flowing and my fingers didn't hurt much anymore. I didn't think too much at the time.< zuowEnBa.NeT >
又过了两天，我的手再一次因摔倒而擦破了皮。我想起了前两天的情形，于是抱着试试看的心情把手又放进了茶水中。奇迹再一次发生了，手上的血又立刻止住了。这一下，我断定是因为茶水的作用而止住了血，但是我却不知道这是什么原因。
Two days later, my hand scraped again due to falling. I remembered the situation a few days ago, so I put my hand back into the tea with a try and see attitude. The miracle happened again, and the blood on my hands immediately stopped. This time, I concluded that the bleeding was stopped by the effect of tea, but I don't know what the reason is.
第二天，我迫不及待地把这个疑惑告诉了老师，老师告诉我，说是因为茶水中含有一种物质，可以暂时麻痹神经，从而让人感觉到疼痛减轻。并且茶水还可以使受伤的毛细血管收缩，闭合伤口，从而起到止血的效果。
The next day, I couldn't wait to tell the teacher about this doubt. The teacher told me that it was because the tea contained a substance that could temporarily paralyze the nerves, thereby making people feel less pain. And tea can also constrict injured capillaries, close wounds, and thus have a hemostatic effect.
无独有偶，除此之外，我还有一个发现。
Coincidentally, besides that, I have also made a discovery.
我们都知道蝙蝠是靠超声波的定位而进行飞行的，那么你是不是觉得它是一个瞎子呢？我不防告诉你，蝙蝠的视力在夜间其实比白天还要好。
We all know that bats fly by locating themselves with ultrasound, so do you think they are blind? I'm telling you, bats actually have better eyesight at night than during the day.
在科学的世界里，到处都有发现，到处都是精彩，有许多的真理等着我们去体验去探索。
In the world of science, discoveries are everywhere, there are wonders everywhere, and there are many truths waiting for us to experience and explore.
