This composition verifies the weather proverb.

Everyone wants to predict the weather. What can we do besides watching the weather forecast? No, I have a trick.

Once, I was reading a magazine and saw a folk proverb written in the book: the cloud goes east, and the car and horse are connected; The clouds go south and the water rises; Clouds go west, covered with cotton-padded clothes; Clouds going north are good for drying wheat. So I went to "consult" a knowledgeable computer. The computer "says" like this: "Clouds moving eastward and northward indicate sunny weather; The movement of clouds to the south and north indicates that there will be rainy weather recently. "

But I don't believe in such a god. How can you predict the weather only by human eyes? So I'm going to try.

But almost every day in those days, there were "no clouds in Wan Li", which always made my experiment impossible. Finally, one day, a small cloud appeared in the sky, but it didn't "move" and just "stayed" in place. After a few days, the wind I wanted finally came and the clouds came. Haha, I can start the experiment.

First, I carefully observe the "direction" of the cloud. The clouds are moving south. I thought of a proverb, "the cloud goes south, the water rises, and the pool rises." According to this, it will rain tomorrow or the day after tomorrow. It will rain tomorrow, and physical education class will have a holiday. I really hope it won't rain tomorrow, and it won't be too late to rain the day after tomorrow, I think.

The next morning, the first thing I did was to see if it was raining outside the window. As expected. There is no shadow of rain in the sky, and I can't help feeling a little happy and disappointed. ...

On the third morning, I just opened my eyes when I heard the sound of pouring rain. I am very excited. Proverbs from ordinary people are the crystallization of people's wisdom, not without scientific basis, but they are observed by ordinary people through careful observation and can be explained in the ever-changing nature. ...

This is my little trick. What about yours?
