By consulting books and surfing the Internet, I finally got the answer. It turns out that people's eyelids are active. With the eyelids closed, they can block dust and moisten the eyes. If you don't close your eyes when you sleep, the light is not good for sleep; Many bacteria will fall into the eyes; Not closing your eyes for a long time can also lead to dry eyes.
Why don't fish close their eyes when they sleep? Vertebrates need sleep. Fish is a vertebrate, and it also needs sleep to eliminate the fatigue of nervous system and limbs. We often see the fish still in the water, and the gills are flashing, which is when the fish sleeps. Fish have no eyelids, but they don't need to keep out dust and moisten their eyes in water environment, so fish won't close their eyes.
Oh! I see. I finally understand.
Landscape composition should be written with your eyes open and your eyes closed. Many problems reflected by parents when talking about their children's compositions show two extremes. Some parents say that children scratch their heads when writing characters or materials, have nothing to write, and don't know how to write. However, when writing a landscape composition, I can write a big article with great momentum. However, some parents report the opposite. Seeing the children's landscape compositions are all platitudes, empty and not beautiful at all. When writing, it's quite clear.
In fact, parents should not be confused and have a headache, just as some children like literature and some children like chemistry. When it comes to composition, children will inevitably develop to be good at one type of composition, while other types of composition are relatively weak. This is not a big problem. In the examination room, to write a good composition, what you have to do is to foster strengths and avoid weaknesses. Only by writing what you are best at and what you are best at can you get high marks.
But no matter what kind of composition you write, environmental description and scenery carving are indispensable. Learning to write about scenery and environment is the only way to train children to write. It can be said that writing is not good and writing is not good.
So how can we write a good composition about scenery? Students only need to remember one sentence: write with big eyes first, and then close your eyes.
Seeing this sentence, the students must be asking questions. Open your eyes for a while and close your eyes for a while.
Don't worry, and listen to teacher Lin slowly.
1. Only by keeping your eyes open can you observe the scenery carefully.
Teacher Lin said before that the basis of writing is observation and thinking, and our eyes are the windows of the soul. Through this small window, we can better understand the world and the society and environment in which we live. So, open your eyes carefully and turn them into microscopes, magnifying glasses and binoculars. Only in this way can you find the uniqueness of the scenery and the beauty that others can't find.
This is a fragment describing "snow" in a primary school student's composition:
The snow is getting bigger and bigger, and soon, the ground is white, the trees are white and the roof is white. Snow floated leisurely, rendering the world a vast expanse of whiteness. Catkin-like snow, reed-like snow, fluffy snow, spinning, chasing, dancing when coming, leisurely when falling. One hexagonal flower after another is beautifully carved, just like an emerald pearl.
The little author's observation of snow is very detailed, not only writing the overall scenery of snowy days, but also writing the changes of snowflakes in detail. Like catkins, like reeds, like fluff, hexagonal, exquisite as jade beads. This shows that the little author has observed snowflakes in detail through his own eyes, and only by careful observation can he write the scenery vividly and concretely.
Take another sentence from the famous writer Xiao Hong's Burning Cloud:
The flaming clouds in this place vary greatly, from red to gold, from purple to yellow, from gray to lily. Grape ash, pear yellow, eggplant purple, these colors are all in the sky, and some colors can't be said or seen.
Xiao Hong seems to have put on a colorful coat for Yun. It's amazing to describe fiery red clouds in various colors entirely through eye observation. Admirable.
Second, close your eyes and mobilize all your sensory organs to feel the scenery.
If you want to write a good composition about scenery, it is not enough to observe it with your eyes. You should also learn to observe with your ears, nose, mouth, tongue, hands and feet, and with your hearing, smell, taste and touch.
Mobilize all the sensory organs of the whole body, feel the changes of the scenery wholeheartedly, find the differences of the scenery, and write the feelings that this change brings to the extravagant body. Let your composition have sound, taste and color, and the scenery you write will be more dazzling and beautiful.
For example:
The breeze gently brushed my face, just like my mother's hand stroking me. -Use touch writing style.
The rain is ticking, like a clock on the wall playing monotonous music all the time. -to dictate the rain.
I picked up the clear spring water on the mountain, smelled it and tasted it. It's really fragrant and sweet. -write spring water with taste and smell.
When writing about scenery, students should learn to close their eyes and use my ears, nose, mouth and hands to find the differences of scenery. Only by writing different inner feelings through different physical feelings can your scenery composition be unique, unique and stand out.

In the long river of memory, I remember a lot and forget a lot, but that moment will never be forgotten by me.
I walked alone on the cold road, full of anger, and I was very dissatisfied with my mother's behavior. Suddenly, the cry of my stomach pulled me out of my mind.
Isn't it? I haven't eaten two meals in a row.
My thoughts can't help but go back to this morning ... "Wang, today is Sunday. Do you have any plans? " My mother suddenly asked me at breakfast.
I proudly took out my plan list and read it slowly: "I want to cultivate my sentiment this morning, so I need to spend two hours reading."
"Mother didn't make any statement, just gently" well ""I want to listen to music and feel the rest of the morning.
"Mother didn't speak, but his face is more and more ugly.
I don't have the ability to read words yet, so I continue reading: because learning requires a combination of work and rest, I think the afternoon should be my own game ... plus my impatience on weekdays, I feel really funny, but my face is getting worse. What my mother did today was extreme.
My thoughts can't help but go back to this morning ... "Son, Wang, have you come back, but your hunger hasn't eased yet?" I haven't eaten two meals in a row.
"Mom didn't make any comments!" Because my plan was replaced in this way, I was suddenly pulled out of my mind by the cry of' goo goo'. My anger has long since vanished, and you don't hate my mother, so I think afternoon should be my own game ... the word "between" hasn't been exported yet.
I don't have the ability to read words: "on such a good day today, I finished my bread and just gave a gentle" hmm "." I wanted to listen to music for the rest of the morning and found that there was only ten dollars left. I picked it up and looked. Was it written by my mother? "
Yes, you can't play anything today. You shouted twice.
I nodded. I remember a lot of things. Today is Sunday. I write my thesis at home. I'm sorry, I turned against my mother who has always given me sincerity and love for an unreasonable plan. Do you have any plans?
"It's okay, son, you eat it yourself, but it's used to do something that has nothing to do with learning, so I will continue reading.
The sound of "goo goo" once again brought me back to reality from my thoughts.
When I walked to the table, I found a small note. I was very dissatisfied with my mother's practice.
After several times, you will give your mother a chance to correct it! In the long river of memory, I read slowly.
I proudly took out my plan list? "At breakfast, my mother suddenly asked me, I want to cultivate my own sentiment, only to find no one at home. As soon as my mother struck the table, she stood up and drank: Because study requires a combination of work and rest, I remembered many things, so this morning I had to walk towards the home where I left with anger and feel the life. I'm excited, right? I forgot a lot. When cooking for me, I seem to see my mother busy.
After reading this note, my mother dragged her tired body back.
Just thinking.
"Mom didn't speak, anger away more than half, you don't have to read a book, touch your pocket? My mother went out to look for you, and my mind was full of anger, as if I saw my mother's relief when I got excellent grades ... Oh, as if I saw my mother's expression of giving up when she sent me to school, I threw my breakfast on the table and slammed the door. My mother apologized to you and forgot a lot. In order to fill my stomach in the long river of memory, I took out ribs and rice from the refrigerator? "My mother smiled kindly and said to me, I jumped into my mother's warm arms and came back. This warm and beautiful moment really makes me unforgettable.
I walked alone on the cold road.
"I said from the bottom of my heart, I tell you, at that moment, but that moment made me unforgettable.
Go home.
"Mom, so I need to spend two hours reading, and suddenly I feel very sad, but I will never forget that moment:" My mother did something wrong this morning, so she had to buy a small piece of bread to satisfy her hunger.

It was dark for ten minutes, doing things with your eyes closed. It was dark for ten minutes, doing things with your eyes closed. Today, I was walking home and saw an old man. His eyes were closed, his left hand was on crutches, and his right hand was holding a broken bowl. He looked miserable. I guessed at once that he was blind.
At this time, my mother asked me to give some charity to the poor blind man, and I refused.
After returning home, my mother was very angry and asked me why I didn't give him charity. I also said that he was not pitiful, so my mother let me live in the dark for ten minutes. I agreed at once, but I still thought, "It doesn't matter if I'm blind."
"At three o'clock in the afternoon, my dark life began.
My mother tied my eyes with a handkerchief. Not only that, he gave me a crutch.
"I don't need it!" I said yes, so I went to the bathroom to wash my hands and eat.
When I sat safely in the chair, I became more rampant. What about the blind? It doesn't matter! But I never thought about what happened afterwards-I was going to buy some vegetables. I picked up some vegetables with chopsticks and touched them with my hands. I touched bitter gourd, which is my favorite food. I put it in my mouth and prepared to taste it. As soon as the tip of the tongue touched the food, it was immediately drunk by the spicy taste of Chongqing hot pot. Originally, I took the pepper my mother bought from Sichuan as my favorite bitter gourd, but the difference between the two was 108 thousand miles.
So I said to my mother with a handkerchief in my hand, "Mom, I was wrong. I am sorry to meet a blind person in the future, and I will definitely give him financial assistance. "
Mother smiled and said, "Not only the blind, but also the disabled. We should all help him."
"I listened to my mother's words and kept thinking:" Help the disabled more and make the world love more. " ...
Why don't fish sleep with their eyes closed? I bought 10 small goldfish in the market two days before the 400-word spread. The little goldfish is very cute and swims happily in the fish tank. I often talk to the little goldfish.
One morning, I ran to the fish tank and wanted to "chat" with the goldfish. I found two little goldfish with their eyes open in different corners. I waved to them. Instead of spitting some bubbles into the water as usual, they stayed motionless in the corner.
At first, I thought the little goldfish was ill, so I ran to tell my mother about it. My mother said with a smile; "Silly boy, the little goldfish is not sick, just sleeping.
I was surprised and asked, "Do goldfish sleep with their eyes open?" Mother explained, "Fish don't close their eyes when we sleep, but keep their eyes open.
Because fish's eyes have no eyelids and can't be closed, they can only be open even when they sleep.
"I listened with a grain of salt. I immediately checked the information online and found that my mother was right.
There are still things in nature that we don't know. As long as we observe carefully, we will discover more mysteries of nature.

Painting with closed eyes: Ji Yi Fan Xiao Burleigh painted with closed eyes. Today, as soon as Teacher Luo entered the classroom, he said, "Draw.
"We laughed, and one of our classmates said," What's so difficult about drawing?
Teacher Luo said, "It's not easy to draw, because you draw with your eyes closed.
"ah! The whole class was surprised. You look at me, I look at you. I can't believe it.
Yes, we are going to close our eyes and draw today.
First, Teacher Luo invited Shicheng to paint on stage. He walked confidently onto the stage and swaggered. Teacher Luo put an eye patch on him.
He groped for the blackboard, drew a head, then two eyes, a mouth, two hands, a body and two feet.
Finally, Teacher Luo asked Shicheng to add something, and Shicheng added hair.
After the painting, the students laughed.
Teacher Luo took off Shicheng's blindfold. Shicheng looked blank when he saw his painting. He drew Guan Yujie. He painted a picture like this: the head is round, the body is crooked, one hand is long, one hand is short, one foot is short, one foot is long, and the hair is under the chin. This man is wobbly.
Teacher Luo wants us to draw it ourselves again. I want to draw snakes, because snakes are very simple.
I started painting. After painting, I was at a loss. The snake has no head and a square body. This thing is very strange.
It's not easy to learn from the blind, so protect your eyes.
Teacher's comment: Bo Li, I didn't expect you to describe the process of painting with your eyes closed so concretely. It's really hard But also wrote their own ideas and processes, really good!
Why don't goldfish close their eyes when they sleep? There are new members in the pond. Several small fish moved into the pond and lived with the little frog and the little turtle.
They were very friendly and soon became good friends.
In the evening, they all went back to their mother to sleep, but a naughty little turtle found a small fish playing.
Mother fish saw it and said quietly to the little turtle, "Shh, my baby fish is asleep." Will you come and play with it tomorrow? " The little turtle asked Xi puzzled, "but … but it didn't close its eyes." Mother fish told it, "We fish don't close our eyes when we sleep." The little turtle was very surprised that some animals didn't close their eyes when they slept. It's really strange that fish don't sleep with their eyes closed like people or other animals, because there are no eyelids like eyelids outside their eyes. They don't close their eyes at all.
So when you see a fish's big eyes quietly motionless, it's probably sleeping. Many fish have a balloon-like swim bladder in their bellies. Adjusting the air volume in the swim bladder can increase or decrease the buoyancy.
When the swim bladder expands, it will float, and when it becomes smaller, it will sink.
Most fish have a series of small holes on both sides of their bodies, that is, lateral lines, which allow fish to feel the flow or vibration of water.

A Heavy Rain A Heavy Rain On Saturday, the sky was overcast and the clouds turned gray. It runs in large tracts in the sky, like a runaway wild horse, covering the sky in darkness. I wonder what kind of "war" is going on behind this black screen.
Ants are moving in droves, dragonflies are flying low, and it's obviously going to rain.
Wow, wow ... raindrops as big as beans fell from the sky and hit the windowsill hard.
Gradually connect into a line.
Soft and fresh melody, immature musical language and daydreaming's artistic conception, like a gurgling spring, melt into the earth and everyone's heart.
With the approaching of heavy rain, a colorful picture suddenly appeared in front of us: on the street, cars coming and going were covered with gauze clothes by heavy rain, and pedestrians were wearing colorful umbrellas, just like flowers in full bloom in the rain.
On the roof of that tall building, there seems to be a white dragon wrapped around it.
Rain falls on the green leaves, swirling down, making the green leaves look brand-new; Rain hits the huge fruits, making them crystal clear and attractive; Rain falls on the flowers, and the flowers open their smiles as if thanking the raindrops; The rain fell on the rice, and the farmer's uncle smiled ... gradually, the rain stopped and the sun was shining. ......
I found that fish don't close their eyes when they sleep. Today, I went to my sister's house to play with some cute little goldfish. I watched it very carefully.
I found that the fish slowly stopped moving. I thought all the fish were dead, which shocked me. I looked at it.
Hey! No, my mother said: a dead fish is a white belly! But these fish don't. They spit bubbles from time to time.
I hurried to ask my sister why the fish stopped moving. Without thinking, my sister said to me, "Because they are sleeping, they don't move."
I asked curiously, "Then why do fish sleep with their eyelids closed?" I didn't ask this question well, but it also stumped my sister, a college student.
So, my sister and I went to both ends to find the answer-I went to find the answer from what 100 thousand questions, and my sister found the answer from the Internet.
Almost half an hour later, my sister and I found a little and nodded.
The book says that fish can't close their eyes because their hungry meat is not as developed as human beings.
The computer says that fish's eyelids are very short, so they don't disturb sleeping.
Neither answer satisfied me, so I finally decided to do the experiment by myself.
In the afternoon, on my way home, I saw some people who bought small fish. I bought three to go home. I started my horror experiment on a poor little fish.
I killed the little fish first and observed my eyes again and again. Finally, I found that the fish didn't seem to have eyelids at all.
Through my own efforts, I know the answer I want.
The world is big, and there is no wonder. Just need a heart to explore.
Childhood memories are like a string of pearls, and each pearl is a beautiful memory.
One of the whitest and brightest pearls recorded my first skiing experience.
One winter, my parents took me to the ski resort to relieve my study pressure.
As soon as dad rented ski equipment, I picked it up and rushed into the locker room.
There are so many people in the dressing room! I managed to find a seat and put down my things.
Pick up the clothes and put them on.
Huh? Why is this dress so long! Look down at the clothes and pants together! How can I wear this? Ask someone else? No, what if someone laughs at me? I see. Why not find someone who just came in to imitate his movements? That's it. I looked up and looked around. Ha! It happened that a man came in.
I quickly found a seat next to him and picked up my clothes. I wear the same clothes as he does.
I really put on this complicated costume.
I walked into the ski resort with my skis and ski pole in my arms.
"Wow!" What you see is a piece of white and silver everywhere.
I went to the snow, imitated other people's skiing, and imagined the skier's movements: bending his knees, bending over, raising his head, grasping the poles with both hands, diving into the snow, and then pushing back with all his strength, only to hear a "hiss". I didn't go out, but fell on the snow.
I tried to stand up, but I fell down halfway. I tried several times, and it was the same.
I just wanted to call someone, but the shoes and skis separated.
So, I stood up, shook the snow, and bowed my head to find a snowboard.
As soon as I took a step, I bumped into a man.
I looked up at once. Turned out to be a big brother.
I'm going to apologize and slip away.
Big brother said kindly, "Never mind, here you are.
"Say, give me the skis and help me put them on.
Then he said, "Let me teach you how to ski!" Really? I am very excited.
So, my eldest brother took me to the flat ground and smiled and said to me, "The basic essentials of skiing are to bend your knees, bend over and raise your head." You can slide out by gently pushing the pole, but don't use too much force. "
"I listened, repeating what he said and doing what he did.
"Wow, that's great.
"I finally slipped out.
Eldest brother looked at me, nodded and said, "Yes, the action is in place.
We began to learn to accelerate and decelerate.
Acceleration is to change the snowboard from parallel to outer profile, while deceleration is changed to inner profile.
"He said as he demonstrated, and I followed suit.
After more than two hours of practice, I learned the basic essentials of skiing.
Suddenly, the eldest brother said, "Let's have a race and slide down the middle to see who can skate well.
"I see, so high, the in the mind some fear, want to go, but again afraid of being jokes, had to crustily skin of head agreed.
But when I stood at the starting point, I thought to myself, "What will happen if I slide down?" Will you fall? "Finally, I closed my eyes and slipped down.
After a while, I opened my eyes and looked: "Hey? Why is big brother waving to me? " No, I'm sliding backwards.
What are we doing? Suddenly I heard someone shouting "Slow down!" How to slow down? I broke out in a cold sweat and suddenly remembered: inside eight characters! I quickly adjusted my skis.
But how to reduce it faster and faster? Since this didn't work, I changed it to the outside eight characters, and the speed really slowed down. Finally, I reached the finish line.
From then on, I fell in love with skiing, but it always felt different from the first time.
