Animal explanation composition

In our daily study, work and life, everyone will inevitably come into contact with composition. Composition is the transition from internal speech to external speech, that is, from compressed and concise language that we can understand to developed and standardized grammatical structure that others can understand. Do you know how to write a standardized composition? The following are six animal expositions that I have carefully arranged for reference only. Welcome to reading.

I have a naughty and lovely puppy. This puppy has white fur. When it runs, it rolls like a snowball. It's called "Little White". A pair of round and smart eyes are hidden in long fluff, and a pair of ears are alert to all suspicious sounds around them. The puppy also has a pair of sharp claws, and its tail is high and arrogant. This puppy is fierce. As long as it hears or sees something a little, it will issue an "alarm" and prepare for the battle.

My dog is not only naughty, but also full of music. One day, I had nothing to do but play music. Who knows, after hearing this, Xiaobai stopped drinking milk and immediately came to the player. I guess Xiao Bai found that the music came from the player! Xiao Bai squatted beside the player, listening to the music and wagging his tail with the rhythm of the music. It's like a little musician conducting a band!

Xiaobai especially likes milk biscuits. I take this opportunity to catch it. I took out a biscuit first, then tied it with thread, and then shook the tied biscuit there, dazzling the puppy. I suddenly stopped shaking and hung the biscuit in front of Xiaobai. Xiaobai immediately recovered and jumped on the biscuit. I moved the biscuit behind Xiaobai to make it empty. This lasted a few minutes. Xiaobai pretended to be "defeated", and I immediately let my guard down. Who knows, he turned around quickly and took a bite of the biscuit. Fortunately, I reacted quickly, and Xiaobai just bit the thread. I want to pull the thread back, so I pull hard, but the harder I pull, the tighter Xiaobai pulls. I thought to myself: it seems that I can't storm, but I can only outsmart it. I stopped the "attack", and it thought I had surrendered, so it was happy to enjoy the cookies. I took this opportunity to pull hard and the biscuit returned to my hand. The puppy barked several times, as if to say, "Hum! If you don't eat, don't eat! " I had to give him the cookies. Xiao Bai ate quickly, as if afraid of being snatched away by me. I touched his head gently and walked away.

Look, this is our little white. Do you like it?

Animal expository composition 2 Hi! Hello, everyone, I am a dolphin swimming freely in the sea. The sea has shaped my body and my life, provided me with abundant food, and let me grow in its embrace.

I am a general term for the cetacean dolphin family. Body length 1.2 to 4.2 meters, weight 23 to 225 kilograms; The beak is short, less than one tenth of the body length; The body is streamlined and slender, and the forehead gradually increases; There are more than 20 teeth on both sides of the upper and lower jaws; Only the first two cervical vertebrae healed, and 3 ~ 4 cervical vertebrae healed in some types. *** 10 belongs to 34 species, distributed in tropical coastal areas of Pacific Ocean, Indian Ocean and Atlantic Ocean, and lives in estuaries and even rivers. We mainly eat fish and squid. Pregnancy is 9 ~ 12 months, and each fetus is 1. We swim very fast, up to 40 kilometers per hour. Although we swim fast, there are no waves or eddies on the sea.

Let me tell you two secrets. Our brain is divided into two parts, one for work and the other for rest. Another secret is that killer whales are one of us.

We live in groups, ranging in number from a few to hundreds.

Forget it, don't say it, my friend is calling me, bye!

My home is not a zoo, but there are all kinds of animals. There are grumpy tigers, slow snails and eccentric monkeys.

My grumpy "tiger" is of course my father. Just say the day before yesterday. After school, dad took me home. When I got home, I finished my homework quickly. Instead of praising me, my father said to me fiercely, "Jiayi, don't do your homework so fast next time, and the quality of your homework is not very good. Don't do it so fast next time." Did you listen to what I said? "

I said, "Dad, don't mind so much. After you finish your homework, you can play. How cool do you think? "

He listened and said, "You, you are so playful." In this way, I was punished for standing for an hour.

My slow snail is of course my brother. For example, yesterday, my father asked my brother to do his homework. My brother hasn't found his homework yet. In a rage, the father said to his younger brother, "Hurry up, hurry up." My brother remembers that he left his exercise book at school. He ran to school and got it back. I was panting when I got home. I went back to my room to continue my homework, but I didn't take a shower until after ten o'clock in the evening. Alas, the speed is really slow.

And the weird "monkey" of the elves, that is, me, because my father told me that when I was 100 days old, only people named Pan would hug me, and everyone else would hug me, so I cried. You see, I was naughty when I was a child, and I am still naughty now. I often do things that make adults laugh and cry.

Is my "animal" interesting?

When I was nine years old, I went to my grandmother's house to play. My grandmother bought six chickens. I'm so happy! Watching them all day. Grandma saw that I liked it so much that she gave me a lovely rooster!

The rooster is yellow all over and its tail is slightly tilted. It walks with a long neck and a beautiful little red crown on its head. How cute!

But a few days later, my mother told me to go home, and I couldn't play anymore, so I had to go home reluctantly ... A few months later, I came to see the rooster with a happy mood. On the way, I kept asking my grandmother: Has the rooster grown up? Have you gained weight? Do you recognize me? Grandma replied that she was in no hurry. Arriving at grandma's house, a beautiful and magnificent rooster came over and crowed from time to time. I was surprised and asked, "Grandma, whose rooster is this?" Too majestic! " Grandma smiled and replied, "This is the villain I gave you!" " "Ah?" I was surprised, so I walked up carefully and wanted to touch it. The cock recognized me! It jumped on my knee and let me touch it and hug it. Grandpa .................................................................................................................................................................... drove the rooster out of the house for no reason. Just then, a strong wind blew the rooster into the river. The cock struggled desperately, but it was useless. Slowly, the rooster sank to the bottom of the river and was drowned. I was sad when I saw it. I was crying alone in my room. ......

Now that I think about it, I feel very, very. ......

On the evening of summer, a mosquito sneaked into the house and waited around the people in the house for a bite. In its eyes, the front is full of tempting dinner, and the back is its own vibrating wings. These two scenes appear in its field of vision at the same time-which surprises us because we can't see our back when we pay attention to the front-but mosquitoes can do it.

As we all know, some insects have a special kind of eyes, called compound eyes. As the name implies, compound eyes are made up of many small eyes. These small eyes can image themselves, so that objects in all directions can be imaged on the retina. This kind of eyes can get a large field of vision and clear images, which is more powerful than the wide-angle camera we use.

Dragonfly's compound eyes only consist of many eyes working side by side, and each eye images separately, but they only need to transmit some images to the brain, instead of handing all the information to the brain for processing, so that the dragonfly's limited brain can quickly process the ever-changing information in the environment. Therefore, dragonflies are extremely mobile, and when they move at high speed, they can keenly catch the prey that moves at the same high speed, so they are called fighters among insects.

The butterfly shuttles through the flowers, and we can see its beautiful shape and bright colors. But on the other hand, what do people look like in the eyes of butterflies?

When the butterfly sees your head, it will think it is a place to rest. Your hair is like a bundle of ropes, and each rope is thick enough to stop it. But if butterflies don't fly or people don't move, then butterflies can't see anything. Because what animals see is mainly the movement of objects.

A toad stayed motionless on the grass. A fly flew by. When the fly flew near, the toad suddenly attacked, stuck out its tongue, caught the fly and put it in its mouth. Then it didn't move as if nothing had happened. For a toad, the garden is a gray screen, and only when things on this screen shake slightly can the toad see it. When the toad jumps, its own movement makes it see the scene around it. When it stops, everything will become blank again.

Animals' eyes adapt to their needs and environment.

The fox's pupil is long up and down and narrow left and right. Because it needs to see things above and below it more clearly, such as a bird in the bush and a chicken in the grass.

The pupil of a horse is wide from left to right and flat from top to bottom, like a flat spindle. Because most horses live in open grasslands, this wide pupil can help them see their enemies from a distance.

A cat's eyes will change three times a day. Under the strong sunlight during the day, its pupil can shrink very small, like a line; At dusk, the pupil will become the shape of jujube stone; It is as round as a full moon in the dark at night.
