"Boom ... boom", the thunder was deafening, the sky was getting darker and darker, and the ants ran faster and faster. The thunder gave me the creeps, but I persisted and wanted to see what had happened. I squatted there and watched intently, sneezing with cold, and the picture of ants moving kept appearing in my mind. It suddenly occurred to me that when it was about to rain, people hurried home. Isn't that the same? I am very happy, because after all, I came up with it myself. But think about it, what does it carry? This needs my further observation. At this time, my mother ran to my side, hugged me and ran upstairs and said, "Oh, you scared me to death!" " What are you doing there? I was so worried. "
Back to the warm home, I sat on the sofa and asked my mother breathlessly, "What was the ant carrying before it rained?" Mother brought me thicker clothes and asked me to change them. Then she said, children, they are carrying food! Food is hard to find because of the rain. That little hole is the bird's nest. They are moving food inside. Don't do such a stupid thing next time! I suddenly realized: "Oh! I see! "
This incident has benefited me a lot. I will never forget the mystery of ants.
I found ants.
Sometimes, you may find that there are always some "lazy ants" among the swarms of ants. Other ants work very hard, busy in and out, but what about this group of "lazy ants"? No wonder people call them "lazy ants", because they don't go out for food, they do nothing all day and look around.
However, the fact tells people that it is this lazy ant who idles all day, after the ant colony cuts off the food source, and when those ants who usually work hard are at a loss, they "step forward" and lead their partners to move to the new food source it has detected. Although lazy ants don't work, they use their wisdom to get everyone out of trouble in times of crisis. It can be said that their contribution is greater and more commendable than that of hardworking ants. A biologist once divided all lazy ants into several groups and put them together. As a result, 80% of lazy ants become hardworking ants, but 20% of ants are still lazy. All the ants in their original ant colony stopped working and were in a mess. Until those lazy ants were put back, the whole ant colony resumed its busy and orderly work. It can be seen that lazy ants are indispensable in the whole ant colony!
Lazy ants spend most of their time on "reconnaissance" and "research". They can observe the weakness of the organization, have the ability to maintain the survival of the ant colony in difficult times, can avoid putting all the ant forces into the work of carrying food, and at the same time keep exploring new foods, thus ensuring that the ant colony can continuously obtain new food sources. It is important that diligent ants exist, but only when diligence and laziness complement each other will the whole group become stronger. The principle of diligence, laziness and laziness, laziness is not necessarily a survival wisdom.
If you are lazy to do housework, you can be diligent in thinking. Sometimes, as a student, you don't have to care too much about the trivial things in life, and you don't have to be obsessed with learning. There is no need to engage in sea tactics. Only by learning to analyze, learn to think and know what things are can we be more calm in the face of life and study. There is a saying that "people who attend are not busy, and busy people will not." Only by jumping out of the narrow vision can we find the key to the problem. Learn the spirit and way of lazy ants, and stand tall to see far. Ask close questions
Have you made any scientific discoveries?
In nature, many animals are our weathermen. For example, ants will move before it rains. Next, I will introduce the personal experience of ants moving.
Once, I went downstairs to play with my neighbors. It's getting dark at this time, and the dark clouds are very big, and it's going to rain. I suddenly found a group of ants under the big tree. The ants moved some dirt and climbed up in droves. I think it's strange. Why do ants move?
When I got home, I immediately turned on the computer and found out why ants crawled when it was about to rain. It turns out that the humidity of the air will be higher before it rains. The long-term survival and evolution of ants, creatures whose nests are built underground, make them very sensitive to the change of air humidity. When the humidity increases, ants will feel dangerous in lower places and move to higher places. Also, ants can predict when it will rain. Their nests are too low and easy to get into the water. Therefore, when it rains, ants will climb higher.
From this I know that it will rain when the ants move. Newton once said, "Observe, observe and observe again." More observation will pay off. In fact, there are many mysteries in nature that we need to explore and discover. No wonder some people say, "observation is the best teacher of mankind."
Everyone has great ideals, and if you want to realize them, you should start with small things.
In order to realize my dream, I began to use my brain and make some small inventions ... When watching TV today, I saw some decorative ornaments made by some people on TV and thought: Can I do better than them? Sure！ I can do it well! At this time, I began to prepare materials.
I searched and searched for a long time, and turned my house upside down, only to find a piece of white yarn and some colored threads.
Having prepared the tools, I began to make decorations.
First of all, I folded the gauze in half, sewed the other three sides with a needle, found a piece of paper as big as the gauze, drew a picture on the paper with a colored pen, put the paper into the gauze and sewed the gauze.
Then, I drew a beautiful picture on the other side of the gauze with a colored pen, and then I sprayed perfume on it.
Finally, I tied the numbered one to the gauze and hung a bell under it. In this way, a sachet is ready.
Look! This is my little invention! Does it look nice?
On summer nights, annoying mosquitoes always bite, suck human blood, spread diseases, and keep buzzing, which makes people unable to sleep well.
I want to invent a special mosquito-killing perfume.
This perfume is made of special materials, which can give off a particularly strange fragrance.
As soon as mosquitoes smell this fragrance, they will immediately lose their attack ability and fertility. Now they can't suck human blood, let alone breed, and they will infect each other. Over time, mosquitoes will gradually become extinct.
This mosquito killer can not only kill mosquitoes, but also be effective against pests such as flies, cockroaches and bedbugs. But it is harmless to human beings and their friends-poultry, livestock and beneficial insects.
Why is this? Because in the process of perfume production, we extracted the genes of the four pests and mastered the "life gate" of the "four pests", so the perfume made is particularly targeted and will definitely become a "super secret weapon" to kill the "four pests" in the future! Having said that, you may ask, how to make this perfume? Hehe, I can't tell you now, my perfume is in the trial production stage! When I apply for a patent and put it into mass production, you can buy it everywhere.
Everyone has lofty ideals, and if you want to realize them, you should start with small things.
In order to realize my dream, I began to use my brain and make some small inventions ... When watching TV today, I saw some decorative ornaments made by some people on TV and thought: Can I do better than them? Sure！ I can do it well! At this time, I began to prepare materials.

Look! This is my little invention! Does it look nice?
I wrote 400 words in my invention composition. I finished my homework early yesterday afternoon.
There is nothing to do. I see a pile of cans in the corner.
I think: If those cans are dumped, it will pollute the environment. It is better to use them, which will not pollute the environment and can be used as waste.
This is the best of both worlds. "
So, I hurried to hold the cans and found all the materials for making small productions.
There are scissors, scotch tape, colored paper, cardboard and glue, and wool.
First, I cut a piece of paper with the same length on the colored paper according to the cans with small scissors.
Then stick strips around the cans and dress him in beautiful "new clothes".
Then cut four squares on the colored paper with scissors.
Stick squares on both sides of cans to make train windows.
Use scissors to make a small hole in the lower right corner and the lower left corner, and use wool to pass through the two holes.
Then cut four round wheels for the train with scissors.
At this time, I accidentally cut my finger and was still bleeding. "Oh, it hurts! I shouted.
I pushed the things next to me to the ground and wiped the blood on my hands with paper.
The person in charge looked at the materials that had fallen to the ground.
Suddenly I remembered what the old market said to us: "Don't give up halfway, just stick to it and you will succeed." .
"I sat on a stool and rang for a while. I suddenly stood up, picked up things on the ground and continued to be my little train.
I made five cars in the same way and connected all the soup doors with wool.
In this way, my little train is finished.
I hurried to my mother's room with the baby in my arms.
I said, "Mom, look at the little train I took.
"Mom looked at it and smiled sweetly.
I will make more small productions in the future, which can not only improve my hands-on ability, but also make use of waste. I'm really happy.
Today, I understand from this matter that you will succeed if you stick to it and are not afraid of difficulties.
My invention composition 20 words My invention "multifunctional pen" With the growth of age, I found that there are more and more nearsighted students in our class! There is an indescribable taste in my heart. So sad! After several months of observation, I finally found that the reason for my classmate's myopia was sitting in the wrong position.
Then I invented the multifunctional pen.
This multifunctional pen is made of aluminum alloy, which is very light and won't get numb when writing homework! Although its shape is the same as that of an ordinary pen, I tell you it has many functions! There are five buttons on the shaft of this pen. The first red button is a pencil. The second pink button is a pen; The third purple button is an eraser; The fourth green button is correction fluid; The fifth button is blue. As long as you don't sit right, it will prevent you from writing.
With this pen, you can save a lot of time and money.
Because it doesn't require you to refill a pencil or ink a pen.
Eraser and correction fluid are infinite, no matter how you use them, you can't use them all.
After listening to my introduction, do you want to buy it? I tell you, fifty cents is not expensive.
This pen is cheap! The "multifunctional pen" was robbed only one minute after it arrived at the supermarket.
I like my invention. What good inventions are there? Let's share them!
Everyone has lofty ideals, and if you want to realize them, you should start with small things.
In order to realize my dream, I began to use my brain and make some small inventions ... When watching TV today, I saw some decorative ornaments made by some people on TV and thought: Can I do better than them? Sure！ I can do it well! At this time, I began to prepare materials.

Look! This is my little invention! Does it look nice? The invention of science and technology is really far away and mysterious to me, but really think about it, in fact, there are technologies everywhere around us. Usually, some students often buy some biscuits and put them at home as snacks, but generally the lid is not good. If you touch it lightly and drop it on the ground, the lid will break immediately, and the biscuits inside will leak out, which is very difficult to clean up.
Moreover, cookies go bad easily after a long time, and I have to throw them away when I can't eat them. So, I racked my brains and finally thought of a perfect way.
I don't know anything about biscuits, but I still know a little about boxes.
The reason why the lid of the biscuit box is not tight is that there is air in it, and the biscuit is easy to deteriorate, and it is also because it comes into contact with air, as long as there is no air in the biscuit box.
But how can I evacuate the air When I opened the drawer to find information, there was a sudden gust of wind when I opened it. By the way, make a small hole under the lid and make a drawer or something on the side. As long as you keep pulling the drawer, the air will be evacuated along the small space, so that the lid of the box won't fall off so easily, and no matter how many cookies you buy, you won't be afraid of breaking them if you just put them in such a box.
You don't need to remember how many times it takes to evacuate the air. You just have to keep pulling and pulling. When it can't be pulled out, there will be no air in it, so don't worry about it. Just pull it gently.
Also, in our class every day, the teacher's hand is cracked because he always takes chalk. Chalk itself is also very harmful to human body. I was heartbroken and anxious when I read it, so I want to invent an induction blackboard when I grow up.
The surface of this blackboard is also glass, but you don't write with chalk, but with an induction pen. After the induction pen writes on the blackboard, the blackboard will automatically display the text. The pen itself has many choices. You can write words in different colors and fonts according to the needs of teachers. Isn't that great? Don't worry, the biggest advantage of this blackboard is that it can save the content of each lesson. When some students can't solve the problem, they can check the class notes and play the recording at any time. Some people can't help but ask, what if there are too many notes? This is very simple. You can delete notes according to the needs of teachers and classmates.
The blackboard can also be connected to a computer, download the knowledge of different subjects from the network, and then transmit it to the teacher for direct use when the teacher needs it in class, eliminating the need for&; gt；
Last night, I had a dream that I was in the twenty-third century.
I looked around and found an uncle waving to me. I hurried over. He saw me coming towards him and said to me, "Hello, little friend, you must be confused, right?" Take it easy. I brought you here with a transporter. I want to show you my newly invented skirt. I'm Dr. Li.
"Say that finish, he took me into a laboratory.
When I walked into the laboratory, I saw a fluorescent yellow skirt. There are three little flowers on the skirt. The first one is blue, the second one is yellow and the third one is green.
I asked Dr. Li doubtfully, "Did you invent this skirt?" Dr. Li naturally replied, "Yes.
"I added," except for three little flowers, it's no different from an ordinary skirt.
"Dr. Li said," don't underestimate these three little flowers, they have a great role! Look at this little fluorescent yellow flower. It plays a role in emitting light.
When you want to join a tour group or need lights at night, just press the fluorescent yellow flower and the skirt will emit fluorescent yellow light.
""How can that skirt shine? " I asked.
Dr. Li replied, "that's because this skirt has been absorbing light during the day." When you press that little flower, the skirt will release the light absorbed during the day, so the skirt will shine. "
"I said," Oh, so that's it! In this way, this skirt goes along the road. Isn't this saving the strength of the country? " Dr. Li said: "This is one of the reasons why this skirt can make everyone like it.
"Dr. Li said," This skirt is also waterproof! If you press the blue flowers, this skirt will make you float in the water.
""What the hell is going on? " I asked.
Dr. Li said, "Because when you press the blue button, your clothes will be filled with gas and lift you up like a life jacket.
""wonderful, wonderful! "I can't help praising it.
"Wonderful, wonderful!" My mother came to me and said it was a dream. I thought about the skirt I saw in my dream several times. Finally, I made up my mind that I must invent this skirt when I grow up.
Today, the teacher asked each of us to invent something. What should I invent? Thinking about it, I suddenly had a brainwave: why not invent a truck excavator? Not yet! It usually takes two cars-a truck and an excavator-to go to the construction site, which is too much trouble. In addition, there must be a lot of thin mud on the construction site after the rain, and the truck is very easy to slip and can't keep up with the excavator. Isn't it much more convenient to add a truck pocket behind the excavator? At the beginning, I immediately found some cardboard, some handmade paper, a pair of scissors and a roll of double-sided tape to start making. Next, please look at my process of making a truck excavator! Step 1: make the front of the car. The front of the car is a cube, so I took a piece of purple cardboard and made it into a small cuboid. Then, I cut some blue handmade paper to make the window and two small yellow discs to make the lights. Finally, I used a brush to get on the door. In this way, a front is completed. Step 2: Make the car body. I used a toothpaste box to make the car body, but the toothpaste box was too long. I wrapped the toothpaste box with yellow handmade paper, and the car body was finished. Step 3: Make a car pocket. Car pockets are actually very easy to make. Just cut the cardboard into a convex shape, fold it and stick it on. Step 4: Make a reptile. I cut the black cardboard into five rectangles of the same size and then rolled it into five cylinders of the same size. Finally, I rolled it into five cylinders of the same size. It's over. Step 5: Make the digging arm. I made a digging arm with a straw and a toy fork. First, I glued four straws together to form a cuboid, then bent the extra parts, and finally inserted two toy forks. Finally, I did the last step: assembly. Stick the car head, then stick the car pocket on the car body, and then stick the track under the car head and the car body.
It's the Spring Festival, and I'm going back to my grandparents' home for the Spring Festival. The little goldfish at home will be hungry for a few days.
I want to invent an automatic fish feeder, which can automatically feed fish every day when we are away from home, and will not make my goldfish baby hungry.
I thought for a long time and came up with a way.
Is to have a machine regularly throw fish food into the fish tank.
Mechanically, I choose to use an electronic watch. With the help of my father, I took off the watch core, leaving only the hour hand, and then lengthened it.
Fish food is put in a funnel made of straws. As long as I can put it away for seven days, coming back is enough to support me.
I fixed them on a cardboard, and the watch hand passed under the funnel made of straw twice a day, pushing the leaked fish food into the small hole on the cardboard and then falling into the fish tank.
After many debugging, the bait device was made.
Put the fish food first, and the clock slowly passes under the funnel. Too slow.
Finally, it pushed two pieces of fish food into the fish tank and succeeded.
I am so happy that I can go to my grandparents' home for the New Year with peace of mind.
A composition on scientific and technological inventions At present, when talking about the spirit of literary enlightenment at the end of 19 and the beginning of the 20th century, the research community has always followed the similar "trilogy" statement of Liang Qichao and Chen Duxiu, that is, the process of China's modern consciousness awakening is divided into three steps: from the shallow to the deep, from the scientific and technological consciousness at the object level to the political consciousness at the system level and then to the ethical consciousness at the cultural level.
This generalization of historical laws is naturally scientific, but the problem is that the existing history of literature is mainly limited to this awakening process as the cultural background of the transformation from modern literature to modern literature, which is basically expounded in the category of social thought and rarely linked to the evolution of literary spirit and aesthetic consciousness itself.
This is a pity.
The author thinks that the change of China people's mental outlook in modern times from the evolution of literary consciousness is closer to the historical truth and more subtle and profound than the direct investigation of their ideological views.
On the one hand, thoughts and opinions are the direct expression of people's rational thinking, with a strong logical color; Literary creation, on the other hand, comes from life and shows the true state of people's thoughts and feelings more from the perceptual level, so it is closer to the truth of history and has complex and subtle characteristics.
On the other hand, the ideas handed down are mostly confined to the intellectual class, mainly an elite consciousness, which is still quite different from the general psychological situation of Chinese people; Literary creation is very different. It not only reflects the author's subjective consciousness, but also is accepted by readers.
At the same time, literary creation, as a living image system, its ideological content and political inclination do not completely correspond to the writer's main idea, and the personalized characteristics of literary creation also determine that it may not necessarily be in tune with the mainstream of political or cultural thoughts of the times.
Therefore, the ideological trend of enlightenment society, culture and enlightenment literature did not produce and develop simultaneously. The ideological trend of modern enlightenment culture originated from the Westernization Movement, while the ideological trend of enlightenment literature rose after the 20th century, and its connotation and value are irreplaceable.
This paper attempts to examine in detail how the ideological trend of enlightenment in the late Qing Dynasty went from shallow to deep from the perspective of literary creation, and how it reflected and connected the three steps of China's consciousness awakening at the turn of modern times.
From saving the country by science to pursuing civilization, the consciousness of saving the country by science, characterized by "learning from foreigners to control foreigners", occupied the center of China culture in the whole Westernization Movement, but the literary creation at that time did not consciously reflect this awakening process. It was not until the end of 19 and the beginning of the 20th century that this theme really attracted the attention of writers and thinkers.
The root cause is probably related to people's ideology itself during the Westernization Movement.
At that time, people focused on the development of objects, while novels/literature were still a "trail" and an empty thing in people's consciousness.
With the awakening of political consciousness in the late Qing Dynasty, the enlighteners finally linked "enlightening people's wisdom" with novels, and political novels were naturally the mainstream of enlightenment creation.
At the same time, novels reflecting the theme of "saving the country through science" appeared. Although it came late, it also became an integral part of the enlightenment thought of novels in the late Qing Dynasty and the early Republic of China.
"Saving the country through science and technology" and "saving the country through industry" may have become history as a whole set of social engineering or political schemes, but as part of the enlightenment trend of thought or as some "fragments of civilization", they will not leave early in the development of literature and will continue.
As mentioned above, the time difference and "logical difference" between the ideological trend of enlightenment culture and enlightenment literature are formed by history and are not transferred by human will.
First, a group of intellectuals translated and introduced many western science fiction novels, such as Biography of Fifteen Chivalrous Men translated by Liang Qichao, A Journey to the Moon by Lu Xun and Travels in the Center of the Earth by Zhou Guisheng.
Then domestic novelists began to create their own science fiction novels.
When writers reflect the awakening of scientific consciousness and the idea of saving the country by science in the form of novels, there is a common narrative mode, that is, they always vividly describe China's use of scientific inventions to make the country rich and powerful, thus defeating the world powers and finally making China people stand tall in the world.
The Moon Tribe, written by a fisherman by the wild river, used a lot of space to make up some scientific inventions, interspersed in a love story of joys and sorrows, which not only showed the great power of scientific inventions, but also expressed that science is the ideal of progress.
Compared with the previous work, the new era of the owner of Bihe Pavilion is more in line with the sci-fi model.
This work is about the imaginary China after a hundred years. At that time, due to China's advanced weapons, it finally defeated Belarus, forcing the latter to make peace actively and signed a treaty that made China people proud.
The theme of the novel's hope for saving the country and strengthening the people through science and technology is extremely clear: "The origin of power is uncertain, and it depends entirely on people."
Huang Zhenqiu, the hero of Levin's The World of Electricity, is a "king of electricity". He made many inventions with electric energy, which led China to rule the world.
Not only conquered Europe, but also colonized the seabed.
Lu's "Revealing the Secret of Xinzi" wrote that after China conquered Europe, it occupied the moon and Jupiter, making them the material basis of China.
Bao's "Flying Machine of Ducks" wrote that some people can fly in the air with the wings of ducks, and his "new artificial man" fantasizes about the method of artificial man.
These novels strongly exaggerate and advocate the incomparable power of science and technology in order to pin on the strong desire of a generation of literati to save the country scientifically.
This bizarre plot and romantic fantasy can express the stagnation in the chest, but it also shows progressive thoughts and patriotic feelings, but the prescription of "saving the country scientifically" can only be an organic part of the whole national salvation plan. If you regard it as a panacea for all diseases, I'm afraid you can only chat with * * *.
Nevertheless, in the history of modern cultural development, the understanding and evaluation of the value of these works is still too low, because the ideological circle has always been too political complex and too weak in rational spirit. When emphasizing the primary significance of saving the country by politics and revolution, it also ignores the weight of saving the country by science to some extent.
Moreover, this sci-fi narrative method can sometimes involve the construction of civilization after the completion of the task of saving the country, and the field of vision tends to be broadened.
As one of the earliest works expressing the consciousness of scientific and technological enlightenment, Liu E's Travels of Lao Can is a representative of this kind of theme.
