生活中的小窍门有许多，例如：口香糖粘在衣服上，放冰箱冷冻一抠就下来了。切蛋糕之前，把刀用热水烫一遍，就不会有奶油粘到上面。水杯里有茶渍，可用牙膏轻松洗掉。今天，我又发现了生活中的一个小窍门。
There are many tips in life, such as sticking chewing gum on clothes, freezing it in the refrigerator and picking it off. Before cutting the cake, heat the knife with hot water once to prevent cream from sticking to it. There are tea stains in the water cup, which can be easily washed off with toothpaste. Today, I discovered another little trick in life.
这天，外面乌黑的天空，潮湿的空气，让我感到今天可能会下雨。这时我来到公园，心情沉重的我望了一下天空，看见燕子在低空中盘旋，还会不时的越来越下降，我不禁产生疑问，为什么燕子要低飞呢？
On this day, the dark sky and humid air outside made me feel that it might rain. At this moment, I arrived at the park. With a heavy heart, I looked up at the sky and saw swallows hovering in the low air, occasionally descending. I couldn't help but wonder, why do swallows fly low?
于是我跟着燕子一路走，就在此时我惊奇的发现：燕子每当接近一个黑点的时候，都会张嘴把黑点吃掉。为了知道黑点是什么，我便近距离观察起来。终于功夫不负有心人，通过我的观察和学习，知道了天空要下雨的时候蚊子也在低空中飞行，而燕子为了吃蚊子，就跟着蚊子一样盘旋在低空追着蚊子吃。以后如果看到这样的情况，就知道天气将会下雨，我们也能及时带上雨伞以防淋湿。
So I followed the swallow all the way, and at this moment, I was surprised to find that whenever the swallow approached a black spot, it would open its mouth and eat it. In order to know what the black dot is, I observed it up close. Finally, hard work pays off. Through my observation and learning, I learned that when the sky is about to rain, mosquitoes also fly in low altitude. Swallows, in order to eat mosquitoes, hover in low altitude like mosquitoes and chase after them. If we see such a situation in the future, we will know that it will rain and we can bring umbrellas in time to prevent getting wet.
通过这次对燕子习性的了解，让我又掌握了一项生活小窍门，还知道功夫不负有心人，平时多观察多学习，做一个有心的人。
Through this understanding of the habits of swallows, I have once again mastered a life trick, and I also know that hard work pays off. I should observe and learn more in my daily life, and become a thoughtful person.
