The explanatory text of nature in Ilya junior high school

Words are really good things. If you know Chinese characters, you can read a thick book and understand the world.

But there is another set of words that everyone who wants to be truly knowledgeable should know. This is the writing of nature. It always has thousands of words. Every star in the sky is a word, and every pebble under your feet is also a word.

Let's look up at the sky. For those who don't know this writing method, all stars are the same. However, some people can recognize the names of many stars and tell the difference between them and other stars. Just as words in books are composed of words, the stars in the sky also form constellations. Since ancient times, when sailors need to find their way at sea, they will read books written by stars. You know, boarding a boat on the water just leaves no trace, and there is no road sign with an arrow that says "Go north from here". But sailors don't need such signs. They have a compass with a magnetic needle, which always points north. They don't have a compass, so they won't get lost. They looked at the sky and found Ursa minor in many constellations and Polaris in Ursa minor. The north is beyond Polaris.

(4) Clouds are also the words of big books in the sky. It talks about present and future. In the best weather, according to the clouds, thunderstorms or lewd rain can be predicted.

Birds, the messengers of the sky, will also teach many skills to those who care about them. If swallows fly in the air

It is very tall and looks small, so it will have good weather. A crow with a white beak flew in and said that spring had arrived at the gate.

The sun is still very hot, and it is a calm sunny day. At this time, there was a strange and uneasy voice in the distance, as if someone was echoing each other in the sky. The sound is getting higher and higher and closer. Staring at the sky, you can finally recognize a fuzzy spider web, as if it had been blown by the wind. Spider webs flew near, and I looked up. It was not spider webs, but many birds with long necks. They lined up in herringbone and neat formation, flying towards the sunny forest. But soon I can't tell these birds apart. It looks like cobwebs again. In the blink of an eye, even the cobwebs disappeared without a trace. They seem to melt in the sky. Only voices came from far away, as if to say, "Goodbye! Goodbye! See you next spring! "

Now, on the construction site, the shovel of the excavator hit a gray stone. In your opinion, this is just an ordinary stone, but for those who know natural characters, this is not an ordinary stone, but limestone. It is changed from broken shells, and shellfish are the inhabitants of the sea. It can be seen that in ancient times, this place, which is now a city, was once the sea of Wang Yang.

Sometimes, when you walk in the forest, you will suddenly see a huge granite stone lying in the middle of the forest, covered with moss, just like fur. How did it get here? Who has the strength to move such a big stone into the forest? Besides, how did it get through the dense forest? So this is called boulder. It was not moved by people, but by ice. These glaciers crawled from the cold north, smashing rocks along the way and taking away the rubble. That was a long time ago, when there were no forests at all. The forest around the boulder grew later.

Pet-name ruby To learn from the characters of nature, you should often go for a walk in the forest or field since childhood, and pay attention to everything. If you don't understand anything, look for an explanation in the book. You should always ask people who know the ropes: What kind of stone is this? what kind of tree is it? What's the name of this bird? What are the footprints in the snow? In this way, when you grow up in the future, you will see the book of nature as clear as a book printed on paper.
