Early in the morning, I found a spider web in the corner of my house, and my strong curiosity drove me to catch a small grasshopper and put it on the spider web.
At this moment, a spider crawled out from the crack in the wall. It vomited a mouthful of white silk next to the grasshopper, wrapped it up and returned to the hole. I am puzzled: why do spiders go back to their holes and why don't they eat grasshoppers? I continued to observe. But after waiting for a long time, the spider just won't come out.
The next day, I was surprised to find that the spider had eaten the grasshopper, leaving only an empty shell on the Internet. I wonder why spiders don't eat shells. In order to find the answer, I read a lot of information and finally found the answer in "100,000 Why". It turns out that after a spider catches its prey, it first wraps it with silk, and then spits out a digestive juice and injects it into its prey. This digestive juice can dissolve the internal tissues of insects composed of protein, and it will become juice after the insects die. Spiders can suck big mouthfuls. Because the shells of insects are not made of protein, the shells of grasshoppers remain intact on the net.
Through this unexpected discovery, I know the mystery of spiders eating. Although this is only a small discovery, it makes me understand a truth: pay attention to learning everywhere. It seems that the essence of Pingla Fanfan actually has endless mysteries waiting for us to explore and discover.
I am proud of my little discovery.
Chinese Unit 3 Composition 2, Volume 2, Grade Four There are two little turtles in my family. They look cute and have round heads like two.
Cute "big head doll". One day, I just looked at these two sleeping turtles and suddenly remembered my discovery?
It was a day last summer, and the bright sunshine shone on my balcony. I thought: these two little turtles are also basking in the sun, so I put them on the balcony floor.
After a long time, I quietly came to the balcony to see what the tortoise was doing. I only see slight back friction. Are you sick? I think today looks a bit unusual. I have no idea what it is doing. After a while, I saw that the slightly smaller turtle also came to the corner and did the same thing to the bigger turtle. I was curious, so I took a closer look. The bricks that the tortoise just polished are all white powder and feel wet. What is that? I really want to know.
After entering the room, I rummaged through all the information books about turtles in the bookcase, and there was no record of this in the information. Are they really sick? How can a turtle do such an unusual thing? Just when I was upset, things became clear. I thought: Isn't this similar to people constantly changing clothes? The tortoise wants to grow up, but the thin cuticle on the shell can't grow up with the tortoise, which will inhibit the growth of the tortoise. Therefore, in order to grow up, the tortoise must grind off the cuticle on its shell for a period of time. Oh! It suddenly dawned on me that it was so simple.
Digging out a Children's Encyclopedia from the bookshelf, this activity is active, and it also allows them to read and finally know the secret of firefly 3' s bright tail. Later, I went back to my house to do other things.
Send information more accurately. For example, when flying high, older turtles call each other on the bricks in the corner. This kind of communicator is not only multifunctional, but also not sick. What is the reason? There are many problems in life that need us to explore and discover. If you are a child who carefully observes things around you, you will find many wonderful and interesting phenomena and see many problems from them, so that you not only increase your knowledge, but also gain happiness.
There are many unknown things in the world, let's find them together!
Today, I am very happy, because I caught a lovely big frog.
I went home happily, put the frog in a glass container, put water on it, and carefully observed the big frog. It is dressed in green and black camouflage clothes, with a bulging belly and four beautiful legs. The hind legs are longer than the front legs. I tease it with branches from time to time, and its hind legs kick and jump, very scared and worried. It croakes at me from time to time, as if to say "let me go".
At this moment, the radio broadcast the contents of protecting beneficial insects and frogs. After I heard it, I quickly checked "100,000 Why", only to know that frogs are good friends of human beings and we should protect them. I knew I had made a mistake, so I said to the frog, "I'm sorry, I made a mistake." The frog croaked at it again, as if to say, "You are a good boy." I quickly took the glass container and ran to the river with the frog to set it free.
I was very happy when I got home.
During the 11th holiday, my grandparents took me to the Qinling Wildlife Park at the foot of Nanshan Mountain. As soon as I entered the door, I saw a mountain with a waterfall, which was completely different from what I saw when I was a child. It is much more beautiful.
We got on the tour bus there first, and I saw naughty monkeys along the way; A goat with a long beard; Antelope with long horns; A big camel with two mountains on its back; A heavy black bear; And zebras in black and white striped shirts; Giraffe with a long neck; Cute pocket deer; King of beasts, tiger; The white jaguar ... is dazzling. Then we got off and went to the aquarium. The show has started! A little sea lion is welcoming us. The coach threw three circles into the water. The little sea lion quickly circled around his neck three times. The coach invited another little sea lion. They both jumped onto the ball on the wall at the same time. Awesome! Everyone kept clapping, one after another. We also went to the museum, where there are many animal models. Grandpa took many photos of me. Among these animals, I like the white swan best, because it is beautiful, its feathers are as white as snow, its curved neck has beautiful curves, some of them dance gracefully on the water, some swim leisurely, and they look so noble and elegant.
I am very happy, because I like small animals, and they left a deep impression on me.
The roses in spring are clustered under the wall, which dispels the lethargy that stayed in the warm wind for a winter. The tender green that is about to drip on the fence is facing the soft morning glow, allowing the sun to embroider blessings on the dark green leaves; Then, the pale pink roses carefully poked their heads out of the bushes, in clusters, scrambling to show their enthusiasm and joy to the world. I am surprised that nature has given such a touching flower endless firepower, dominated her "brevity" with abundant vitality, wrote her short youth, and made her little time full of vitality. Shouldn't life be like this? The golden age only lived for a few years. Of course, he should fill the emptiness with vigorous vitality, show his enthusiasm for life, and have a hard-working youth! In summer, under the scorching sun, a small tree on the roadside stands upright, sticking out some decadent leaves. Although it was irradiated by strong ultraviolet rays, it just stood upright and looked like an elegant gentleman. To my surprise, nature endows young trees with such endurance, enduring the scorching sun and the destruction of wind and rain. It is precisely because of this patience that we are stronger and can grow up in hardships. Be patient when you are alive, and don't haggle over every ounce. Only by learning to be patient can we have a broader mind and "be patient for a while and be calm;" Take a step back, broad sky "mind! The rain, falling in drops, seems endless.
The rain on the ground gathers into a trickle and winds to the distant line where water and sky blend. It seems that I have confidently shouldered the heavy responsibility of "moistening things quietly". Yes, water can be condensed into ice and snow or turned into clouds. If you are willing to be a backwater because you lose self-confidence, then the price you pay is too indifferent. Life is a one-way street, and it is impossible to go back, but some opportunities often change the trajectory of life. Seize the opportunity, seize the opportunity confidently, believe that I will dominate my destiny, and tell myself confidently: I will definitely accomplish the "great mission entrusted by God". Life is brilliant and gloomy, ordinary and great, sometimes in an instant. Deciding a person's life and the whole destiny, sometimes in an instant. Learn to struggle, learn to be tolerant, learn to be confident, learn to seize opportunities, achieve life and change the trajectory of life. You-the master of fate!
The other day, I saw that the onion outside my window was covered with black bugs, and some bugs were flying around it. After a few days, some onions gradually withered. I asked my father to buy some pesticides to get rid of these bad things. However, dad said, "Insecticides are toxic and bad for your health." Hearing this, I lost confidence like a deflated ball.
At this time, an idea came to my mind: although there is no pesticide, I can do it myself!
At first, I took a pot of water and poured it on those hateful bugs. I thought the worm would be scared away by the water, but the worm didn't mind the water at all and still flew around the pot of onions. I didn't lose heart when I didn't succeed the first time, so I started the second experiment.
"Since you are not afraid of cold water, you can't use boiled water!" I said disdainfully. I brought a pot of freshly boiled water and poured it into the onion pot. As I expected, those bugs panicked and crawled around on the onion. Looking at their hectic appearance, I smiled with satisfaction and spit out four words from my mouth: "culpable of punishment!" "
After a while, I came out to have a look again and found that those bugs were still "occupying" the onion pot, which surprised me greatly. Angry and annoyed, I grabbed an ashtray next to me, poured the water and ash into the onion basin, and left angrily.
The next morning, I went to see the pot of green onions again. I was surprised to find that all the bugs in the pot were gone, leaving only a pot of green onions. Now I don't understand: how did those bugs disappear at once? Really ... grey water? I asked my father why ash can kill insects. Dad said, "I don't know." I ran into the study again, intending to check the information, but I still couldn't find the answer after searching for a long time.
I believe I can find the secret. There is science everywhere in life. In this world, there are many secrets waiting for us to explore!
Unit 3, Book 2, Grade Four Chinese Composition 7 Wang Qiang and Wang Chengdu and I like to play with small animals and dissect animals. Once, an old farmer smashed several mussels with bricks and ate them. I saw a light blue liquid flowing out of the broken mussel, so I asked him, "What is this?" Uncle said, "It's the blood of mussels." When I heard this, I felt and thought, blood is red. How can the blood of mussels be light blue? "
This afternoon, we went to the river to touch mussels. After a while, we touched a lot. We chose the biggest one and decided to do an experiment. We put the mussels in the washbasin. When it opens its shell, we insert a wooden stick and leave a gap between the two mussels. Then I saw a light blue heart beating gently. We carefully cut it with a sharp knife and saw a light blue liquid flowing out of it.
At this time, we believed the farmer's uncle's words, and the blood of mussels was indeed light blue, indicating that the blood of animals was not all red.
I often see people eating frogs in restaurants, which makes me sad.
Frog, also known as frog. This is because many people often eat them. But do you know that a frog can eat fifty or sixty pests and more than 200 pests a day? You can eat fifteen thousand pests in seven months! What a great contribution this is! Raising a frog can reduce the use of 0.5 mg of pesticides, increase a green space for nature and increase a guarantee for human health. Some students may ask, "What is the relationship between spraying less pesticides and people's health?" I will tell you: "pesticide residues on crops can kill pests, but it will also endanger human health." Although the dose of 0.5 mg is negligible, because many a mickle makes a mickle, if there are more frogs, more doses will be saved.
Protect frogs, let's act quickly! Although frogs are rich in nutrition, people are prone to parasitic diseases if they eat too much. Eating frogs is not only unhealthy, but also harmful to crops and yourself.
There is a cartoon in Unit 3, Book 2, Grade Four Chinese: It shows a man chopping down big trees with an axe in his hand, and the trees turn into bare stumps one after another. Seeing this cartoon with my own eyes, I was lost in thought.
Everyone says that we should protect the environment and care for trees. How much can we do? Trees are indispensable to human life. They absorb carbon dioxide harmful to human body first, and then release fresh air, and do their duty without complaint. It has also contributed to beautifying the environment and making great contributions to mankind.
But humans don't know how to repay the greenguard tree. For their own benefit, they waved sharp axes and hacked wildly on the green trees. Lush trees have turned into stumps, and birds have lost their homes for survival, and they are helpless about human behavior. The "trees that have not yet died" are heartbroken and sad to see their brothers and sisters "needlessly" sacrificed. Due to human ignorance, the desert constantly devours oases. Those felled trees are used by human beings to build houses and factories, which is only beneficial to human beings, but it poses a great threat to the environment and has serious consequences.
Here, I sincerely appeal to the world: Please save trees. If green trees disappear from the earth, then human beings can't survive. Let's mobilize to save trees!
Chinese Unit 3 Composition 10 Not long ago, my happiness was lost, so I looked everywhere.
I swing, and when I swing higher and higher, I feel like flying. At that moment, I discovered that the secret of happiness is to keep a childlike innocence forever.
I came to school with my schoolbag on my back and listened to the teacher's simple lecture. When the teacher asked a difficult question, I raised my right hand and gave a wonderful answer, which won applause from the teacher and classmates. At that moment, I discovered that the secret of happiness is to master a wealth of knowledge.
On my way home, I lent my new "pet elf" to my classmates. I jumped with excitement when I found that my classmates also liked elves. At that moment, I found that the secret of happiness is to share happiness with friends.
My mother came back from work. I watched her sweating profusely, handed her a towel to wipe the sweat, and poured her a cup of cold boiled water. My mother drank it all at once and smiled comfortably. At that moment, I found that the secret of happiness is to honor my parents.
I discovered the secret of happiness. As long as I have a grateful heart, I will always have happiness!
After reading Revelation of Nature, I also got some inspiration from nature.
For example, I saw an ant looking for food, but it couldn't move. In the blink of an eye, a group of ants helped carry it back to the hole. The enlightenment they gave me was: to unite and cooperate and help each other in study and work; When the geese fly south, there is a leading goose in front, which is arranged in a herringbone shape for a while and in a herringbone shape for a while. They are disciplined, and they are afraid that they will fall behind. The enlightenment they gave me was that I should obey the command when I take part in any group activities; Bees are busy collecting honey among the flowers, which shows that only hard work can bear rich fruits.
On Saturday morning, I accompanied my mother to the market to buy food. In the morning, the market is really busy and people come and go. There are also the cries of selling vegetables; My mother and I walked and watched; I want to eat fish; My mother took me to the fish stall, where there were many people. Just when my mother chose the fish; I found someone selling frogs; See those frogs trapped in the net bag; I feel very sad. Frogs are our friends, and farmers call them the protectors of crops.
Its tongue is very long and can quickly eat many pests, such as flies, mosquitoes, moths, caterpillars, yellow worms and so on. A frog can eat 50 to 100 mosquitoes or 700 to 1000 pests a day, which is a great contribution. It can also eat pests in the water. Let's protect frogs. Please don't catch frogs, the protector of crops.
Early in the morning, I went out to play and suddenly found an ant crawling out of its nest. What is she doing?
Soon, a large number of ants filed out from the nest, and I soon understood that the little ant turned out to be a night watchman. When he sees food, he will send a telegram happily, and if it is predicted that it will rain, he will send a telegram sadly (because it will rain).
After a few hours, I was impatient. Alas, the new nest is finally repaired! Look at the new nest, then look at the old nest, obviously the new nest is much better!
That night, my parents and I went for a walk by the river. While we were walking happily, suddenly, a water snake was crossing the road. I screamed with fear! Dad said, don't shout when the snake comes, or it will come at me.
After a while, the snake was in the water
I don't understand why, so I started to look up information as soon as I got home. I finally know, because I saw an agricultural proverb in a China book: ants move along the snake aisle, and there will be heavy rain tomorrow. It will rain tomorrow.
The next day, it really rained cats and dogs!
One afternoon, it was very sultry. I was playing with my father's "sweetheart"-orchid on the balcony when I suddenly saw a small snail climb up a leaf. "Are snails beneficial insects or pests?" "Why do you leave a long line when you climb?" "Where are the nose and eyes of the snail?" This series of questions appeared in my mind.
So I decided to do an experiment myself to find out these problems.
"Where are the eyes and nose of the snail?" According to the former method, I put a cabbage leaf on the ground and caught a snail. This snail seems to know my pains, and obediently let me see its eyes, nose, big tentacles and small tentacles. The big tentacles are eyes and the small tentacles are noses. Through this series of experiments, I really benefited a lot! I not only discovered the secret of snails, but also understood a truth: if you want to make inventions when you grow up, you must find problems from an early age and learn to solve them.
The fourth grade, the second volume of Chinese Unit 3 Composition 15 Life will experience many things, but one thing has benefited me a lot-sericulture.
One day, I came home from school and saw a silkworm seller, so I bought some to raise at home. Among these silkworms, I like this one best. It used to be dark and dejected all day, but now it is getting bigger and bigger, and the dark skin has turned white. Isn't this the story of the ugly duckling turning into a white swan? Silkworm babies have brought me countless happiness. I take care of the silkworm baby like a mother, feed the silkworm baby with mulberry leaves and clean up the feces every day. Once, I went to the bathroom to wash my hands, and my mother was washing clothes. Suddenly, my mother accidentally bumped into the basin and the water splashed on my pants. I was about to be angry with my mother, but I stopped. I remembered my sericulture career. I haven't done anything for my parents, but whenever I make a mistake, my parents will forgive me generously. Why should I be angry with my parents instead of tolerating them? Thinking of this, I bowed my head in shame and ran to find silkworm babies to change their mulberry leaves.
Different things will get different enlightenment. Competition is a trivial matter, but it may make you the most profitable thing in life.
