1. Essay on Wild Animals

We need to protect wild animals because if we protect them, they will be friendly to us humans.

Swallows, for example, help us eat the pests in our fields. If we humans kill and capture them, will they eat the mosquitoes that often come to scratch us for a better life? Without swallows, our surroundings become a lot of pests, these pests are very bad for us humans ah!

Let me give you another example. For example, frogs, frogs can also help us eat pests in the field, can be said to be the police in the field. We support hunting them, once there are no more frogs, more and more pests in the field, pests continue to eat vegetables, will we have a good harvest?

I also give an example. For example, the woodpecker, the woodpecker is a doctor in the forest, it can help us eat the pests in the tree, so that the tree to restore health. If we kill them, there will be more and more pests in the trees and the trees will slowly diminish. There will be floods and earthquakes on the earth without trees.

I'll end with an example. For example, owls, owls catch voles, is good for us humans, but humans often hunt them. Without owls, voles would increase. The crops and vegetables eaten by the voles will be, and we humans will not have a good harvest as well.

So, we have to protect the above animals. At the same time, we have to protect other wild animals!

2. Write an essay about wild animals

When you taste a plate of mountain delicacies, have you ever thought that the animals are decreasing in batches? When you hunt and kill an animal, do you hear the animals crying? Gourmets, can you bring the dead animals back to life one by one? Hunters, can you bring the dead animals back to life and return them to nature? It is well known that there are fewer and fewer wild animals in China.

More than 10 species of animals, including wildebeests, hartebeests, and reindeer, are completely extinct, and more than a dozen species of wildlife, including giant pandas, gibbons, tigers, wild elephants, and albino dolphins, are facing extinction! Due to the ignorance, greed and stupidity of a small group of people, hunting and killing animals everywhere has caused an imbalance in the ecology of the earth, resulting in incalculable losses! Changes in the natural world and human activities are also related, such as war, resource development, population growth and rural urbanization, resulting in the deterioration of the living environment, so that the animal resources have once again been seriously damaged, the endangered wildlife is decreasing. People arbitrarily destroy the ecological balance, a large number of hunting and killing animals, the prey caught one by one sold to restaurants, hotels, restaurants, etc., and then made into a dish, and then has been sold at a high price to diners to eat.

Restaurants, hotels, and pubs kill so many innocent people for money to satisfy some people's hobbies. People, wake up! Protecting animals is also protecting ourselves.

Eliminate indiscriminate hunting and killing, so that we and animals live in the same blue sky. Let's start from a young age, protect wildlife, care for wildlife, so that more people can throw themselves into the action of protecting wild animals.

3. Primary school essay: I found

I found that the cat itself will cure

We may feel strange to see this topic: how can the cat itself cure the disease? What kind of disease is cured? How do you know this? How, you still do not understand?

The cat can cure itself, and what is it?

It was a year ago. One day, I wrote homework under the balcony, write a while, hand sore, put down the pen and looked up at the sky, only to see the sky azure, like a cleaned sapphire, so that people see the heart relaxed and happy, and all of a sudden eliminated fatigue. I lowered my head and was about to continue writing when I suddenly realized that "Blackie" (the cat's name) was circling around the flower pot as if looking for something. Curiosity made me put down my pen once again. I wanted to see what "Blackie" was up to.

I saw "Blackie" stretched out his right paw, in a large pot full of weeds, ruffled. I was shocked and couldn't help but shout out, "Blackie, what are you doing?"

"Blackie" didn't seem to hear me, and didn't pay any attention to me.

After a while, its head stretched to a clump of grass. I took a closer look, this is a kind of grass called "Newton grass". It is said that this kind of grass can cure stomach pain. "Little black" with its mouth to bite the grass, chewing and chewing, not long, the whole grass was swallowed into its stomach.

I thought, "Cats like to eat fish, how can they eat grass? Could it be, could it be healing? This idea flashed in my mind, can not help but remind me of a mythological story: a snake was wounded, it moved to a piece of grass under the tree, rolled over a few times, rolled a few times, the wound actually healed, and there is no trace of being hit.

Thinking of this, I looked at the "little black", only to see its stomach slowly wriggling, issued a "gibberish" sound, I know that it is going to vomit (it is always like this when you want to vomit). As I expected, "wow" sound, "black" the belly of all the things vomited out. I look, those vomit something inside some dark green, this is "black" just ate the "Newton grass" right?

I also thought: "Blackie" ate the spoiled fish, stomach pain, so he went to eat grass, right? And "Newton's grass" is just the right cure for tummy ache. After eating it, he spit out the spoils and got well.

In order to confirm this, the next day, I took some spoiled fish, mixed into the good fish for the cat to eat, and sure enough, in the afternoon, the cat went to eat "Newton's weed", and after eating it, he spit out the spoils in his stomach as usual.

Since then, I have learned a truth: all kinds of creatures know how to protect themselves. When people are sick, they go to the doctor, and when cats are sick, they look for herbs to cure their illnesses ......

4. About Animals What I Discovered Essay

Everyone may discover some wonders of a certain thing, and in the process of discovering it, there are many experiences, and of course, even I, who don't like discovering things, will discover the wonders of things, and if you don't believe me, please If you don't believe me, please come and listen carefully.

It was in a hot and cool summer ......

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a beautiful dolphin-style diving action, with the water droplets fell on the lotus leaves like a naughty child, hit a roll, turn over, and then jumped up, a flawless diving action was born.

I thought, the lotus leaf must be wet by the water droplets, the lotus leaf and no towel, it is easy to catch a cold, and it can not take medicine. I dried it, sort of give it a chance to sunbathe . So, I even dragged the lotus leaf out of the pond. Touch the lotus leaf with my hand, well, furry, texture is not bad. Then look closely, eh? Why is it dry? I do not believe, and put the lotus leaves into the pond for a while bath, pick up a look, still dry. Is not the lotus leaf is too hot, hot, then thirsty; thirsty, then want to drink, then swallow the water droplets, right? It must be so. I would like to see how the lotus leaf can drink water without a mouth. So, I don't care if the lotus leaves feel cold or not, and let it soak for a while. This time, I put my eyes wide open, watching with excitement, heart also from time to time "thump" jumping, afraid of missing the water beads are eaten by the lotus leaf scene. But, contrary to expectations, the water beads are not eaten by the lotus leaves, but like marbles "pop" into the water.

"Why don't the lotus leaves get wet?" I asked. I walked into the study with the question, opened the "100,000 reasons". A check, oh, it turned out to be the surface of the lotus leaf has a layer of nanometer composed of nanoscale nanofilm. Nano-thin film laid on the surface of the lotus leaf, so that the lotus leaf becomes smooth, as if the lotus leaf put on a waterproof jacket.

From this incident I understand a truth: to get more knowledge, just by asking is not enough, but also more access to books.

5. Essay on wildlife

I have heard that the Dongshan Wildlife Park is famous, but it is a pity that I can't have a feast for my eyes this time the school organizes a spring trip, and it finally fulfills my dream of visiting the wildlife park.

Just arrived at the East Mountain Wildlife Park, I was intoxicated in front of this green mountain scenery. Lush green triangular coconut, the growth of vibrant cocoa coconuts, gurgling water, ancient trees, such as the green grass, birds and flowers, it is true to its name. We first visited the "four unlike" elk, the national protected animal, and then saw the tallest animal on land - giraffe and the largest bird on land - ostrich. --The giraffe is the tallest animal on land and the largest bird on land is the ostrich.

Next, we entered the first section of the beast area - the lion area, but most of those lions are sleeping, really strange. Immediately after that, we went to the tiger area, and saw a fierce tiger, was eating a chicken, and the blood, which made me feel disgusted and afraid. After leaving the tiger area, we went to the black bear area, I saw a black bear and another black bear in a fierce "battle", it was really interesting! But I looked to my left and to my right and I didn't see a single bear, so where were the bears? Were they still hibernating? At this time, my classmates told me to look up, I looked up, there is a black spot on the tree swaying around. I took a closer look and realized that it was the black bear.

After leaving the Beasts of Prey area, we came to the largest animal on land - the elephant's place. As soon as we saw the elephant, many students screamed, and some students took out their cameras to take pictures of him.

Immediately after, we visited the dwarf horse, tiger, sika deer, Hainan Po deer, Australian ostrich, peacock, pearl chicken, bactrian camel, white buffalo ...... but the most memorable is the lion and tiger beast "Pingping" and "Anan".

"Pingping" and "Anan" may be regarded as the most dazzling star of the Dongshan Wildlife Park, because they are currently breaking the longest surviving pair of lion and tiger beasts in China. They were born on May 2, 2005 and have survived for 355 days. When I saw them, I encouraged them: must live through 1000 days, break the Guinness World Record, for China to win the honor!

At about 11:00, we reluctantly left Dongshan Wildlife Park.

Returning home, I lamented: most of the animals I saw were endangered species, but why do we humans still kill them? We should call on those cruel massacres, put down the hands of the shotgun, come together to protect these animals!

6. I discovered

I discovered the secret of ants

What is the secret of ants? We all think that ants are a kind of gluttonous little animals, eat everything, no matter sweet, sour, bitter, spicy or salty, no matter what, ants only know a "eat" word. But I don't think so. I think ants do not eat bitter, spicy. You do not believe, do not believe to take a look at a small experiment I did it!

That day, I had nothing to do, so I picked up a book to read. While reading, I took out a sugar, tore off the sugar paper, and threw it to the ground. When my grandmother saw it, she immediately picked it up and said solemnly, "Aren't you afraid that ants will come to our house to eat your candy paper?" I said inexplicably, "What? Ants can eat candy paper? Don't ants only eat sweet things? Why do they eat paper too?" I looked at Grandma with curious eyes. "Sugar paper also has sugar in it, just less than sugar." Grandma said with a straight face. I nodded my head as well. I then gingerly went to the kitchen, took a piece of paper and put some sugar on it, and took a couple tiny pieces of paper out and put some salt, sour sauce, medicine, and pepper on each. Went out into the alley to do an experiment. After waiting for 5 minutes the ants didn't come, so I wanted to throw away the 5 tiny pieces of paper. Suddenly I saw an ant crawling around. So, my thought of giving up was dispelled. I then squatted down again to watch it carefully. The ant touched Tim's pile of sugar with its antennae, and then touched salt, sour sauce, medicine and pepper with its antennae. Crawling again to the place where they had originally come out of their holes, after a little while more, one ant crawled out of the hole, each touching each pile with its antennae. Then went to the sugar, salt, and sour sauce and carried some food back to the hole. On the way back, each ant they met touched each other with their antennae. Probably saying, "There is food there, go carry it and eat it."

......

After no more than 2 minutes, a pile of sugar, a pile of salt, and a whole lot of sour sauce disappeared without a trace.

From this experiment, I realized that ants don't eat everything, ants eat only things that contain sweetness.

I finally discovered the secret of ants.

Today's composition class, Mr. Yuan took out two cups, two eggs, a spoon, some salt and two cups of water, when Mr. Yuan took out these things, everyone was talking, I wondered, "This time it is an experiment?" Wait a while, it is indeed an experiment, (in the water) how to float the eggs?

Mr. Yuan put the egg in a cup of water the egg suddenly turned from slim to chubby! Just like a tennis ball. Mr. Yuan asked us to recommend a group of one (a) person (on the podium to do the experiment), the first person is Tang Ningyu, the second person is Ling Yuxuan. Mr. Yuan put the cup (filled with water) on the incline, put the fragile egg into it, the egg as soon as the cup immediately (lying) in the bottom of the cup to sleep, lazy, is the egg is also a sloth. The experiment has officially begun! Tang Ningyu salt, Ling Yuxuan stirred (water and) eggs, eggs in the bottom of the cup (rotating) stood up, is not sleeping wake up! Classmates said, "It's standing up! It's standing up!" The second time Ling Yuxuan added salt, Tang Ningyu stirred, the egg again rotated, as if floating, and then stumbled down, the students reacted to "how to come up, and then go down?" Third continue to add salt, continue to stir, the egg floated out of the water, like a swimmer, the water also turned white! The experiment was successful!

Today, I know that water has buoyancy, the original experiment can give us so much fun!

On a Sunday morning in the summer vacation, when I woke up from my sleep, it was dawn, and my parents had already left for work. When I got dressed, my stomach was already growling. I hurriedly washed my face and brushed my teeth, and then went to eat the thin rice that my mom had already prepared. As I ate, I played with the things on the table. Suddenly, I realized that there was an egg on the table! I turned it hard, it was so funny! I took another egg from the refrigerator and spun the two eggs together with both hands at the same time. The original egg turned fast and steady, and long time, but just out of the refrigerator out of the egg but can not turn two or three rounds, on the crooked lying on the table does not turn.

I was immediately interested, and went to turn the "strike" egg, but still the same. The original egg is still spinning happily!

It's a good thing that I've been doing this for a long time.

I look at the "strike" egg, and then look at the egg is still spinning, really do not see any difference!

I look at the "strike" eggs, and look at the eggs still spinning, really can not see any difference. I touched the "strike" eggs, and touched the eggs that were spinning happily just now, are the same smooth, heavy, and there is no difference! I'm not sure what's going on here, but I'm not sure what's going on here.

I kept spinning the egg again, exploring why it was spinning and not spinning. Suddenly, the "strike" egg "popped", fell to the ground; egg liquid flowed all over the place. I hurriedly took a rag from the table to wipe the egg liquid on the floor, but unexpectedly brought another egg on the table to the floor. Huh, this one is a cooked egg! However, I calmed down and thought: why does the cooked egg spin fast while the raw egg spins slowly and doesn't even move?

I looked at the two broken eggs, the cooked egg white and yolk were coagulated together as one; the raw egg white was liquid and the yolk was semi-solid. When I rubbed the cooked egg with both hands, the whole egg rotated together; when I rubbed the raw egg, the white and yolk could not be mixed together at once, and the egg naturally did not rotate.

Ah!

Ah! I discovered the secret of the cooked and raw eggs turn or not, I can not wait to tell everyone that I have a "great" discovery.

7. Essay on the protection of wild animals

Hello, Mr. Owner: Animals, like us humans, have thoughts, feelings, and their own way of life, and have the right to freedom.

We destroy animals' habitats without their consent; we hurt their bodies without their consent; we decide their deaths without their consent. Have we ever considered their feelings, have we ever thought about their thoughts, have we ever considered that it is up to them to decide when their lives will end.

We human beings are now advocating the love of life, the love of life. Our human life is very precious, is not the animal's life is not worth to cherish. Perhaps there are times when we humans don't want to die but don't have the right to choose, but such things are a minority after all. We can't treat animals as a part of our human race, as our friends, as our family.

Our standard of living is getting higher and higher, information is getting more and more developed, and the demand for material life and spiritual life is getting higher and higher. But can we remove the "eating wild animals is good for the body" from our material life? Nowadays, there are people who say that eating wild animals can make us live longer; there are also people who say that eating wild animals is nutritious; and there are even people who say that eating wild animals is good for the brain. I think this may be true, but human beings can not blindly follow, some animals have carcinogenic substances.

Moreover, even if wild animals are good for us to eat, have we ever thought that when we are killing them to our heart's content, the death of human beings is approaching? I think anyone who has read a book is familiar with the term "biological chain", right? Once the biological chain is destroyed, it means that the large biological families will disappear from the earth as fast as possible, and human beings will eventually end up dead. By the time mankind gets its comeuppance, I'm afraid there will be no room for redemption, right? Anyone knows a maxim - there are no pills of regret to buy in the world. Why is it that if we know this saying, we cannot ponder over it, think about it and put it into practice? As long as we always keep this saying in mind, always think about practicing it, when we see that innocent creatures at the table, will we still happily want to eat them? Will we still make such a big mistake?

Whether the end of the world in 2012 will happen or not is not certain, but if we do not protect our environment, protect our precious wildlife, I am afraid that the end of the world will happen from uncertainty to certainty.

Now the world's plant and animal species are disappearing from the earth at a maximum rate, sometimes even one species every minute. If this trend continues, won't humans disappear? Can't human beings envision that? Can't they plan for the future? Can't they plan for future generations? Can't we plan for the long-term development of the human race? We are now living a happy life, do not want to eat and wear, high-speed information developed, these are our ancestors left behind, these are their hard work and hard work. As a descendant, do we want to destroy their achievements like this? Our future generations are so unqualified? The first thing you need to do is to make sure that you have a good understanding of what you are doing and how you are doing it.

The Earth is so destroyed, human beings do not feel pity?

So, for the long-term development of mankind, cherish the protection of wildlife, cherish our beautiful life, and further develop the achievements left by our ancestors.

I hope I can help you.

Butterflies and bionics

Colorful butterflies brocade color charm, such as heavy moon striped crested butterfly, brown veins of the golden spotted butterfly, etc., especially glow-winged crested butterflies, whose hind wings in the sunshine sometimes golden, sometimes emerald green, and sometimes from the violet to blue. Scientists have brought great benefits to military defense through the study of butterfly colors. During World War II, German troops surrounded Leningrad and attempted to destroy its military targets and other defenses with bombers. Based on the lack of awareness of camouflage at the time, the Soviet entomologist Schwanwitch proposed to use the reasoning that the colors of butterflies are not easily detected in flowers to cover military facilities with butterfly-patterned camouflage. As a result, despite the German army's efforts, the military base in Leningrad remained safe and sound, laying a solid foundation for winning the final victory. According to the same principle, later people also produced camouflage clothing, greatly reducing casualties in combat.

Artificial satellites in space due to constant changes in location can cause sudden changes in temperature, sometimes the temperature difference can be as high as two or three hundred degrees, seriously affecting the normal work of many instruments. Scientists are inspired by the butterfly scales will automatically change the angle with the direction of sunlight and regulate the body temperature, the temperature control system will be made of artificial satellite blade radiation on the front and back of the two sides of the heat dissipation capacity of a large difference in the style of the shutters, in the rotating position of each window is installed in the temperature-sensitive wire, with the temperature can be adjusted to the window opening and closing, so as to maintain the internal temperature of the satellite is constant, solving a major problem in the cause of space. The space industry in a major problem.

9. What I discovered Animal Essay 400 4th Grade

I discovered the mystery of animals

I have a very cute kitten in my house.

This kitten is very cute, gray-white and gray-white fur, which is soft and comfortable to touch, a pair of pointed ears on its round head, and a pair of blue eyeballs in its big sockets that squint into a line during the day, but become very big, very bright and very expressive at night.

Why is this? I thought and thought, once, I was taking a midday nap, before I went to bed, I closed all the curtains, the room was immediately dark, after I woke up, I pulled the curtains, strong sunlight came in, I squinted my eyes, at once, I thought of cats, could it be that during the daytime the light is too bright, resulting in the eyes squinting into a slit, while at night it is the opposite?

I also found out one thing, my cat will grow a beard at birth, what does he want this beard for? Because I heard my teacher say: every thing in an animal is very useful, otherwise it will degenerate. "I'm very strange, then check the Internet for information, understand, the cat's beard so long to the sides, because the cat's beard is good as a ruler, slightly longer than the cat's body, into the hole, the cat first to use the beard than the hole, if the hole is smaller than the body, the cat does not go into the hole in the hole, if the hole is bigger than the whiskers, the cat will go into the hole.

When a cat sleeps, it always puts its ears on the underside of its forelimbs near the ground. I find it strange, is this position comfortable to sleep? What kind of benefit is there in sleeping this way? So, I learn the way the cat sleeps lying on the ground, at this time, I heard a footsteps, but raised his head, but can not be heard, after a while, only to hear the footsteps, but not just clear, I lie down again, more clear than just now it! At once, I understood, the original, because the ground sound transmission is much faster than in the air, so once a mouse walks, the cat will immediately wake up, this is the cat to sleep on the ground.

Cats like to eat fish and mice. Cats like to eat mice, probably because mice are active at night and cats are active at night, so cats like to eat mice, but what about fish? Why do cats like to eat? I went online to check the information, it turned out, the cat often in the night activities, the body must have a large number of oxalic acid, this can improve the night vision of the material, and fish and rats are one of the most oxalic acid animals, so rats and fish naturally become the cat's meal, if the cat can not get this material for a long time to supplement the visual acuity will be lowered, shall not be able to see in the dark, it is not more to catch the rats.

In nature, there are many mysteries waiting for us to discover, as long as we pay attention to observe, we can find something.

There are many mysteries in nature waiting to be discovered.
