One day, we were looking at the science books as we normally would, waiting for the teacher to come and give us a science lesson. After a while, the teacher came in, cleared her throat and said to us, "Students, let's do an experiment today.
Immediately, the students cheered because this was our first time doing the experiment. We quietly followed the teacher to the science lab, and it was very large, the size of two classrooms. I saw that the experimental equipment was already waiting for us on the table.
The teacher showed us first, and she skillfully picked it up. I saw that the students were watching intently, staring at every action made by the teacher. The teacher said after doing it:
When turning on the alcohol lamp, be sure to pay attention, otherwise it will happen**. When the students heard this, they were all terrified. "Next, please do it once in a group.
The teacher said. Everyone in our group was scared, afraid that the alcohol lamp would blow them up, and they didn't dare to take the lead. At this point, we had to guess and decide.
Rock-paper-scissors. "Haha, Huang Yuheng lost. He said:
You didn't just say that you lost first. "He's so sloppy? When I usually see him so strong, I think he is very bold!
Unexpected, so timid. So, we had to do "rock-paper-scissors" all over again. "Ah--- I can't help but scream, I lost. I'm going to start doing it.
I thought to myself: I can't be religent, I'm the squad leader, I can't do this, I must succeed.
The materials in front of me are: iron stand, alcohol lamp, test tube clamp, glass, glass piece, match. I brought the iron stand in front of me.
Pour about 500 ml of water into a glass, place a mesh on the iron stand, and place the glass on top of the mesh. Then use a test tube clamp to clamp the glass piece. At this point, it's time to light the alcohol lamp.
What to do? What to do? My heart is like fifteen buckets of water--- seven up and eight down.
But I can't back down! That's what my heart thinks. I finally decided to insist, I carefully and meticulously swiped the match, at this time, I saw that the people in our group were far away from me, and I knew that they were afraid that they would **.
Please, don't be so cowardly," I shouted to them. Even though I said that, I was actually scared too. I slowly lit the alcohol lamp from the bottom up.
I carefully placed it underneath the wire mesh. On top of which I put a slice of glass on top of the glass. At this point, we wait for the rain to form.
After 3 minutes, I saw that the other people who were slower than us just now had raindrops. But why hasn't our group yet. To be on the safe side, we consulted with our teachers.
The teacher said, "Of course you can't pull so much water. In this way, we were scolded by the teacher.
Then, we learned the lesson of our last failure, and this time, we just put 200 ml of water. "Success, success" The people in our group cheered, happy for my success, and at this moment, my heart was also sweet.
This experiment taught me that science is magical, and as long as we dare to experiment boldly and think boldly, then we will succeed.

All of them refer to focusing only on immediate interests.

It has a slender and elegant posture, a pale green body color, and long wings that are as light as gauze. The neck is soft, and the head can be turned in any direction. The praying mantis spread his wings extremely wide, its wings erected and erect like sails.
Praying mantis is widely distributed all over the world, especially in the tropics.
The species is the most abundant, and the praying mantis is specific to phototaxis, so in the hot summer, it is often seen under the street lamps of the city, in addition to the specific good and aggressive characteristics of the praying mantis.
Habits:The praying mantis has a wide distribution, many insectivorous species, large food quantity, strong fecundity, and long predation period, which is a rare natural enemy insect resource. It can prey on a variety of pests that harm crops, vegetables, fruit trees, and forest trees.
Such as aphids, leafhoppers, bollworms, whiteflies, bridge-building insects, fan boat moths, poisonous moths, spiny moths, and beetles.
Pine caterpillars, blind bugs, bean moths, pine aphids, poplar caterpillars, locusts. flies, etc.

The Book of Insects is a book of natural observations by the French writer Jean-Henri Fabre, and the chapter "Praying Mantis" is impressive. In this chapter, Fabre Kezhong's observation of the praying mantis is very nuanced, and the description of the mantis's amazing skills in preying on insects is breathtaking.
It can be seen from the text that Fabre is very passionate about the observation and study of living things, and he uses his words to describe the survival and predation skills of this unique insect in nature. He is not only recording the living habits of the praying mantis, but also feeling the wonder of natural life, for this natural beauty and unique vitality, he is full of awe, which is also the core idea of "Insects".
Therefore, it can be said that the chapter of "Insects" expresses the author's deep feelings for nature, the careful observation of life and the awe and awe of the unique way of survival. At the same time, it also encourages us to pay more attention to natural ecology, cherish and protect nature, and call on human beings to live in harmony with nature.

Long ago. One summer a small fly rested on a pine tree.
There's a spider crawling up and trying to eat the fly.
As soon as the spider pounced, a big drop of pine resin dripped down from the tree, enveloping the fly and the spider in it.
They struggled a bit, and finally they didn't move.
The pine resin continues to drip down and eventually accumulates into a ball of pine resin, which encloses the two little worms.
And then the water flooded the forest, and those balls of pine resin were submerged under the sediment.
Thousands of years passed, and the pine resin ball became a fossil.
There was a fisherman walking along the beach with his son. The boy dug up the amber.
From that piece of amber, we can speculate on the details of the story that took place 10,000 years ago, and we can know that in ancient times, there were flies and spiders in the world.
I hope it will be useful to you, and don't forget to give me a thumbs up.

The main contents of "Praying Mantis Catching Cicada" in "Insects" are as follows:
From the outside, it is not intimidating, on the contrary, it looks quite beautiful, it has a slender and elegant posture, a pale green body color, and long wings as thin as yarn. The neck is soft, and the head can be turned freely in any direction. Only this insect can gaze in all directions, and it can really be described as a six-way sight.
It even has a face, and all this constitutes the tenderness of such a small animal.
The Book of Insects, also known as The World of Insects, was first published in 1879 in the first volume and in 1907. It focuses on the external morphology and biological habits of the insects he has observed and studied, and realistically records the instincts, habits, labor, and death of several common insects.
Background of the creation of "Insects":
Fabre was born in December 1823 into the south of France in the family of a poor peasant.
When he was in elementary school, he often traveled to the countryside and stuffed his pockets with snails, mushrooms or other plants and insects. Fabre entered the Normal School at the age of 15 and was offered a position as a junior high school mathematics teacher after graduating. He spent a month's salary on a book on entomology and was determined to become a writer of the history of worms.
Fabre was self-taught, earning a bachelor's degree in physics and mathematics from university, and two years later in natural sciences. At the age of 31, Fabre received a doctorate in natural sciences. He has published a series of works, such as "Sky", "Earth", "Plants", and "Uncle Paul Says Pests".

"Insects" is a masterpiece of Fabre, an outstanding French entomologist and writer, and it is also an immortal work. It is a fusion of the author's lifelong research results and life perceptions, to observe the nature of insects, to transform the world of insects into a beautiful text for human beings to obtain knowledge, interest, beauty and thoughts, and to be faithful to the overall style and expression characteristics of the original French book as the selection principle, so that Chinese readers can appreciate the true face of "Insects" for the first time.

1.It is important for the cicada to be able to climb up and down its burrows easily, because when it climbs out into the sun, it must know what the climate is like outside. So it had to work for weeks, even a month, to make a solid wall that was suitable for it to crawl up and down. At the top of the tunnel, it has a finger-thick layer of soil to protect and resist changes in the outside air until the last moment. >>>More
