B.500-word composition comes from the ear principle.
The human ear consists of three parts: the outer ear, the middle ear and the inner ear. The human ear has the functions of hearing and balance. Normal people's ears can distinguish about 400 thousand different sounds, some of which are very small, which can only make the eardrum move by one tenth of the diameter of hydrogen molecules.
When the sound is emitted, the surrounding air molecules start a series of vibrations. These vibrations are sound waves, which propagate outward from the sound source. After the sound reaches the external ear, it is introduced into the external auditory canal through the sound collection function of the auricle and reaches the tympanic membrane. The eardrum is the dividing line between the outer ear and the middle ear. It is as thin as paper, but it is strong. When sound waves hit the eardrum, it will cause the eardrum to vibrate.
In the middle ear cavity behind the eardrum, there are three interconnected ossicles. Each ossicle is only the size of a grain of rice and is the smallest bone in the human body. Their names come from their shapes. Next to the eardrum is the mallet (like an iron mallet), followed by the incus (like an anvil) and finally the stirrup (like a stirrup). When sound waves vibrate the eardrum, the ossicles also vibrate. These three ossicles actually form a lever system, which amplifies the sound and transmits it to the inner ear.
The last stapes of the three ossicles is connected to a small membrane called oval window. The oval window is the gateway to the inner ear, and there is an organ specialized in hearing in the inner ear-cochlea. When the stapes vibrates, so does the oval window. On the other side of the oval window is a cochlear catheter filled with liquid. When the elliptical window vibrates, the liquid also begins to flow. There are thousands of hair cells in the cochlea with tiny cilia at the top. When the liquid flows, the cilia of these cells are impacted. After a series of bioelectrical changes, hair cells convert sound signals into bioelectrical signals, which are transmitted to the brain through auditory nerves. The brain processes and integrates the transmitted information to produce hearing.
In addition, the inner ear also contains a very important organ-semicircular canal. The semicircular canal is composed of three small rings perpendicular to each other, which is dedicated to the sense of balance in the three-dimensional space of the head. When there is something wrong with the semicircular canal, dizziness may occur. Hearing is an indispensable communication channel in human social life. However, the most important thing is that hearing makes us feel the environment, and produces a sense of security and participation. Listening is very important for health.
C. The Story of Eyes and Ears (about 400 words)
One night, Mingming fell asleep, his eyes closed, his ears rested, his mouth slightly closed, leaving his nose on duty. Look, he is breathing and working hard!
In the dead of night, the more I think about it, the more unfair I feel: "Hum, why can they all rest, but I can't rest from morning till night. I have to have a fair meeting tomorrow, and I have to rest!" "
The next night, the moon climbed up the branch quietly. Late at night, I fell asleep again. At this time, nose, eyes, mouth and ears quietly jumped down from Mingming and gathered in the chair. The nose spoke first: "hey, I have to work every day and I can't rest for a moment. I won't talk in the morning." I really want to work all night. Really tired! " "My ear said unconvinced," yes, I have to get up early every day to make good preparations. Flexible eyes said: "since everyone is so hard, let's take turns to rest together!" " Monday, I have a rest. Tuesday, nose rest. On Wednesday, my ears rest. Thursday, rest your mouth. How about working together on Friday, Saturday and Sunday? "Everyone says it's a good idea.
Monday is here, my eyes are resting, and other partners have to work. I obviously have to go to school in the morning, because my eyes are resting, so I can't see clearly. I walked crooked and staggered, and almost got hit by a car. Fortunately, I heard the sound of a car and ran away, but I escaped this robbery and ran into another robbery. I accidentally bumped into a telephone pole and my nose was bleeding. My nose is not happy, but I am in pain. Who is it? It is also because I can't see, so I come to school. As a result, the teacher dictated to the students. Obviously, none of them are right, and I got a big duck egg. When I got home, my mother saw it, and I was so angry that I was beaten so hard that my nose was black and blue, and my unlucky nose was almost flat. This day, everyone is really having a hard time!
It's Tuesday's turn to rest your nose, and your eyes, mouth and ears have to work. Now that my eyes can see, I'm not afraid of being beaten anymore. When I came to school, I saw flowers everywhere. I obviously want to smell the flowers, but my nose is resting, so I obviously can't smell anything. What a pity! At breakfast, I saw something delicious, but obviously I couldn't smell anything. what can I do? And because my nose is resting, I can't breathe, so I must ask my mouth for help, otherwise, I may suffocate. At this time, I clearly thought, "If I die, won't my nose die with me?" It seems that I really dare not rest. "
On Wednesday, my ears should rest. I'm still sleeping. My mother called him, but he didn't hear. My mother was angry and picked up a chopstick and gave him a good beating. I woke up with a "ah" and went to school without brushing my teeth or washing my face. When I came to school, my classmates were chattering, but I was sitting alone in my seat. Suddenly, I don't know who patted Mingming on the shoulder and looked back. Oh, it's red. Hong Hong said, "Mingming, let's play games together!" " But Mingming couldn't hear, and kept asking, "What, what ……" Red thought Mingming was fooling her, so she was very angry and ignored Mingming. "Rinrin Bell" came to class, and the students returned to their seats to listen to the teacher. Obviously, they can't hear at all. The teacher asked a question, please answer it clearly. Obviously, he looked at the teacher like a fool. The teacher was angry, came to Mingming, pinched Mingming's nose and asked Mingming, "Teacher, why did you pinch my nose?" Everyone laughed, but obviously, I don't know why everyone laughed at him, because obviously I couldn't hear him!
Today is Thursday, it's your turn to rest your mouth. In the morning, I got up clearly. Obviously I can hear things this time. When he came to school, he wanted to say "good morning" to Honghong, but when he found Honghong, he just wanted to talk, but his mouth was closed and he couldn't make a sound. There is no way. Mingming had to take out paper and pen from his schoolbag and write the words "good morning" on the paper. After class, the teacher asked questions again, knowing that he would answer them, so he raised his hand and invited him, but he couldn't speak. So he had to go to the podium, pick up the chalk and write the answer on the blackboard. The teacher was surprised and asked Mingming, "Mingming, why don't you just say it and write it out?" Mingming wrote a few words on the blackboard, "I don't know why I can't talk." The performance these days, the teacher felt very strange.

G. Fairy tale composition with eyes, ears, nose and mouth, less than 200 words.
Today, I'm going to tell you a bizarre article. (It's an argument about the five senses)
When I was going to sleep tonight, I suddenly heard my eyes, ears, nose and mouth arguing about who contributed the most:
Look in your eyes and say, "I have contributed the most." If the host doesn't have me, I can't see some beautiful scenery, such as Guilin landscape, Huangshi scenery, beautiful scenery and so on. " So my contribution is great, and no one can be better than me! "
Not to be outdone, the ear said, "You said that you contributed a lot, and I, I contributed a lot! Because, if the master didn't have me, he couldn't hear what others said to other masters, and he couldn't hear beautiful music melodies, such as Beethoven's songs, Da Vinci's songs and some other songs. This is why I have made great contributions! "
Hearing these words, my nose seemed to explode with anger and said, "I have made great contributions!" " Because, if the host doesn't have me, I can't ask for something delicious, so I have a lot of credit! "
I said proudly, "You are nothing, my contribution is great, because I can't eat delicacies or KFC or McDonald's without my master, so my contribution is the greatest!"
Later, the eyebrows spoke: "You guys are too arrogant! You have your own advantages. Don't argue You have exhausted your host. So, get a good sleep quickly, lest your master can't get up tomorrow and be scolded by the teacher. So, be quiet!
Later, they gradually quieted down and began to become silent. After coming down, I gradually fell asleep. I don't know what happened afterwards.
H. the voice echoes in the ear, and the composition is 500 words.
The voice echoed in my ears.
The gentle voice like water guides my direction. -inscription
When the cheerful school song sounded, I just stepped into the class gate, shook my head casually, let my hair hang down on both sides, pushed the door open and shouted enthusiastically; Report! In exchange, the students snickered and sat down with you, as gentle as water.
Your voice is very special, different from the heroic math teacher, the hearty English teacher and my loud voice. You always tell us vivid articles in a gentle voice, which benefits me a lot.
When the gentle and soothing landscape sounded, I skillfully took out my calligraphy book. Looking at the love-hate green cover, I sighed helplessly. Alas, when will my handwriting look as good as the above? Difficult, really difficult! I picked up the pen in frustration and brushed it angrily twice, and a "masterpiece" was born. It's really a mountain peak on the side of the mountain, and the distance is different! Then you came up to me gently, took my hand and said, "You can't write like this. You have to be horizontal and vertical, pay attention to details, but you have to trim your margins. " After that, I raised my hand and drew a circle on my "horse". "You see, the words should be written like this." You wrote a regular script on the side of my "Weeds". I looked up at you blankly, and you smiled at me. Long eyelashes and crescent-shaped eyes, like butterflies flapping their wings, have a bright smile, which is not even as good as your blue coat. You encouraged me, and my written determination took root in my heart. I will definitely write it. I swear in my heart that I will promise you that your gentle voice echoes in my ears like a drizzle, leaving a little rain.
The cheerful class sounded, and I was anxious to turn over the homework in my schoolbag. Then a bolt from the blue hit me on the head, without it! When you ask me to open my homework, I can only sit there and wait to be criticized. Unexpectedly, you said in a soft voice like the wind, "Never mind, pay attention next time." So far, I have never made that mistake again. Every time I finish my homework, your voice always echoes in my ears.
Teacher, your gentle voice always echoes in my ears, like a bright light, illuminating the road of Nightcrawler, like a star, guiding me forward!
First, the role of the ear 400 words composition
Ears are the treasure of our human body. Listening to lectures, music and stories ... can't be without ears, but we don't care about professional knowledge. Today we are going to do some experiments about ears to arouse our attention to ears.
First, let's do the first experiment-the sound of an electric fan. The teacher asked a classmate to turn on the electric fan, which slowly turned and made a "buzzing" sound. After a while, the voice became louder and louder, from "buzzing" to "swishing". The teacher turned off the electric fan again, and the noise became louder and louder, and finally I couldn't hear it.
Then, we did the second experiment-funny sneezing.
The teacher selected five students to go on stage, then discussed and began to perform. Mao Bin first performed a cold sneeze, only to see Mao Bin shaking his chest with his hand, and suddenly a sneeze came out of his mouth. Then, several students also performed their sneezing, which was very interesting.
Finally, the third experiment came, which was "Listen to the sound and guess the action". "
The teacher told us all to close our eyes, listen to the sound and guess what the teacher was doing. There was a bang, but it was the sound of moving the pedal to close the door. There's another beep. Oh, it's the sound of dialing the phone. ......
These three experiments let me know the function of ears, and also know that we can't live without ears, so we should care about our ears.
