Write a composition about myopia.

1. Jiangsu Education Publishing House, Grade 6, Volume 6, Chinese Composition Unit 6 The Problem of Myopia Recently, there are more and more nearsighted people in schools, especially senior three students.

On campus, many students who come in and out wear small glasses. A first-grade child has a childish face, but thick glasses have been hung on his nose.

I wonder if I didn't see it. I was shocked at first sight. There are quite a few students wearing glasses! We really want to know why, so we have worked hard here. With the help of the teacher, we made a survey on the myopia rate and eye habits of young pioneers with myopia.

When looking for information, I saw a set of shocking figures: the incidence of myopia among adolescents in China is the second in the world, with an incidence rate as high as 50%. Among them, the myopia rate of primary school students is 22.78%, junior high school students are 55.22%, senior high school students are 70.34%, and college students are as high as 80%.

The number of primary and secondary school students suffering from myopia accounts for 60% of the total number of students, with more than 60 million patients. Ranked first in the world.

After reading this net article, I can't help but tremble and wonder: "Why are so many primary school students nearsighted?" Why are so many college students nearsighted? The number of primary school students to college students is gradually increasing. Is myopia related to age? "All the questions rose in my heart. I looked for other materials and guessed that the reason for myopia was bad eye habits and increased learning tasks.

With the help of teacher Jiang, we got the students' eye chart in September 2007. After statistics, I got the following myopia (visual acuity less than 5.0) data: 12 myopia among 92 students in senior one; Eight of the 82 students in Grade Two are nearsighted; Seven of the 92 people in Grade Three are nearsighted; Five of the 94 people in the fourth grade are nearsighted; Among the fifth grade 130 students, 15 is nearsighted; Forty-two of the 133 students in grade six are nearsighted. I found that the number of nearsightedness decreased gradually from grade one to grade four, but it increased again in grade five and six, especially in grade six, accounting for about 30% of the total number of students in grade six.

"What the hell is going on?" We made a further investigation on myopia. If you don't know life, you don't know the sweetness of life.

Similarly, how do you know the cause of myopia without asking your classmates? We adopted the inquiry method. Come to the sixth grade class and ask your classmates.

One of the students said that he often plays games online at home, often stays up until midnight and plays all night on holidays; Classmate B said that she likes reading and writing on her desk, and sometimes she does her homework while watching TV, which is very close to TV. Classmate C said that he often quarreled with his classmates when doing eye exercises, and often wiped his eyes with dirty hands when his eyes hurt. Student d is short and fat. He said that he likes sweets such as chocolate and sugar, but he doesn't like foods containing vitamins such as tomatoes and oranges. Many students talked about their daily bad eye habits.

Through the inquiry, I learned that students have many bad eye habits, and found that the main reason for their myopia is 1, reading too long, not paying attention, and working long hours for eyesight. 2. Lack of proper physical exercise and outdoor activities.

3. The reading and writing posture is incorrect. 4. Parents don't pay attention to their children's eyesight health.

5. Stay in bed and read in the carriage. 6. Read and write in too strong and too dark light.

7. Watch TV and surf the Internet at close range and for a long time. 8. Don't do eye exercises seriously.

9. The nutritional structure is unreasonable. 10, heavy study burden and great psychological pressure.

1 1, often wipe your eyes with dirty hands. 12, found that hyperopia was poor, and did not check and treat it in time.

I also learned on the internet that myopia is very unlikely; The causes of myopia are congenital myopia and hereditary myopia, but the possibility is only 1% ... The eyes are the windows of the soul, the tools to explore everything and an indispensable part of our bodies. If we lose our eyes looking for light, our world will be dark.

Students, we must protect our eyes and be the masters of them. Remember, never do the above 12 points, and pay attention to your daily eating habits! We should develop good hygiene habits, protect our eyes and the windows of our hearts with scientific methods! Teaching objective: 1. Find an interesting content, conduct some surveys among students, and record the survey results in time.

2. Analyze the survey results with statistical methods learned in math class and talk about your own feelings. 3. Express your opinions around the statistical process and results.

4. The writing of the investigation report is eclectic and can be accompanied by various statistical charts drawn. Teaching time: two periods of teaching process: the first period 1. Stimulate dialogue and interest. How interesting it would be to study practical problems in study and life with the statistical methods learned in math class! Have you done such a survey? Second, the empirical survey 1, the teacher wants to know, how many students in our class have done such a survey? I haven't done such an investigation. Please raise your hand if you want to do an investigation.

2, statistical summary 3, group communication, recall the investigation process Students communicate their own investigation process in groups of four. Requirements: It is necessary to clearly explain the reason and purpose of the investigation and the implementation steps of the investigation.

Fourth, their respective reports 1, please list the purpose of your investigation and the implementation steps one by one according to the teacher's requirements, which can be in the form of words or charts. 2. Students organize themselves as required.

What conclusions did you draw from this survey? Write down your findings, too. 4. Report by name and exchange survey results.

5. Complement each other and make suggestions. 5. Collective communication and suggestions. Ask the students to talk about their feelings or suggestions according to the statistical data and results. 6. Instruct students to write one by one according to the purpose, process, results and conclusions of the survey, or directly write a complete composition with appropriate icons, which will be more vivid.

In the second class, students write, teachers patrol and correct in time, then students copy the composition.

2. How to write 400 words in myopia composition? First, ask questions.

According to the survey, there are more than 5 million blind people in China, and the number of people with low vision is nearly10 million, especially children and adolescents, and the prevalence rate is extremely high. According to the latest data of the national student physical health survey, the incidence of myopia in primary school students, middle school students and high school students in China is 22.8%, 55.2% and 70.3% respectively. Why are so many people nearsighted? Is it just caused by bad eye habits? Myopia, is it related to age?

Abstract of intransitive verbs

Entering the senior grade and the information age, thick glasses have become a "trend". Don't let us give up our vision because of this "trend". Students, we can't hesitate any longer. We must appeal to the whole world to be more like eyes. You know-"eyes are clear pearls, eyes are the windows to the soul" ...

4. Who will write me a composition about the inconvenience that myopia brings to life? Hello, the first topic is to prevent myopia from growing up healthily. There is such a story: once upon a time, there was a man with high myopia named Daming. One day, when he came home from playing vinegar, he saw a small black spot on the wall and thought it was a nail, so he hung the vinegar bottle on the "nail". Who knows just hang up, I heard a bang. It turns out that Daming mistook flies for nails. The next day, Daming went to play vinegar again. When he got home, he saw another "fly" on the wall. Daming gets angrier and angrier as he thinks about it, so he swats flies with all his strength. Who knows, this time it's a real nail. As soon as Daming gave up, the vinegar fell to the ground again. Although this is a joke, it can be seen that myopia has brought a lot of inconvenience to people's lives. This is only one aspect. Myopia is likely to bring other diseases. In our class, when I was in grade one, I only saw one classmate wearing glasses. Now in the fourth grade, there are eight students wearing glasses alone, and many students' eyesight has also declined. This is no small matter. Students should never underestimate it. If a person's myopia reaches 600 degrees or above, it will lead to retinal detachment, glaucoma, macular degeneration and other terrible diseases. You know, these diseases are enough to make people blind! Think about how terrible life is without light. In fact, there is no way to be nearsighted: first, you should have good habits: when reading and doing homework, keep your eyes one foot away from the book, and don't bend your head to do homework or read on the table; Keep your chest one punch away from the table; Hands should be one inch away from the pen tip; We shouldn't spend too much time writing, watching TV and playing computer games. No matter how wonderful the program is and how interesting the game is, we should stop and have a rest so as to keep our eyes bright and healthy forever. Second, pay more attention to eye care: do eye exercises on time, check your eyesight regularly, eat more foods containing vitamins, and close your eyes when you are tired, which can protect your eyes. Third, pay attention to the symptoms of discomfort in the eyes; For example, when the eyes are "painful, swollen and jumping", it means that the eyes are sounding an alarm, and we must not be careless. In short, I can't disturb you at ordinary times, and I can't think that I am nearsighted. It's annoying to ask yourself to do so many things every day. This kind of luck will eventually make us taste the bitter fruit. Eyes are the windows of the soul, so protect them. We should start from small things, start from small things, and start from good habits, so that we can have healthy eyes. The second one is caused by myopia. I once saw an advertisement about eyes, which said: Eyes are the windows of the soul, please put glass on your window. At that time, I thought the advertisement was particularly funny. However, what I never expected was that a few years later, I actually let my eyes ride on my nose. Alas, people really don't count. Today, I regretted it, but it didn't help. If I had known this, why did my eyes bring endless troubles to my life? Take them off when you eat, when you don't do your homework, and even when you cry! The trouble of wearing "glass" on your eyes lasted for three days and three nights. These are nothing, what impressed me most is that on the first day of school, I went to the wrong classroom! It is not surprising that this phenomenon appears in comics, but it actually happened to me! On the first day of junior high school, I came to school in high spirits and knew nothing about what I had written. Because our class is at the end of the corridor, and I am a foreigner, and I happen to be nearsighted. I looked up from afar, as if I saw seven years written on the door.

The word class. God knows, it says seven years.

Ben, a "tragedy" just happened. Looking at the strange faces next to me, I didn't notice anything strange. After all, I am a new classmate. How many can I know? That's it. I am here

The whole class sat for about half an hour, and suddenly the teacher said, "We still have seven years."

Ben. . "I suddenly a surprised, what? Seven years.

Ben. ? God, get out of here! No choice but to bite the bullet and say to the teacher, "teacher, I-I'm in the wrong class!" " "Before the teacher responded, I ran out like an arrow and there was a burst of laughter behind me. I really want to find a crack in the ground. After another wave of unrest, this way

Ben burst out laughing over there.

The head teacher called my mother. As soon as I entered the classroom, the head teacher asked me why I was late. It's a long story, and I can't explain it clearly. . Myopia makes me suffer from myopia, which brings a lot of inconvenience to my life. Finally, I want to warn my classmates to take good care of their eyes and not to cover themselves with a layer of "glass"! The trouble of myopia, do you want to know why I changed from good eyesight to pseudomyopia? Because my reading posture is wrong! As soon as my mother mentioned my myopia, she began to sigh: "How good your eyes were when I was a child, how bright, bright and dark, bottomless, and people know what is the purest in the world." But now ah ┅ ┅ "seems to have lost a big baby. Also blame my eyes for disappointing. But now, my eyes are not as bright as before, and they are a little less shiny. But, more mature. My eyes seem to be lovers' eyes-one eye has good eyesight and the other eye has a little poor eyesight. In class, sometimes I can't see the words written on the blackboard clearly because my eyes don't live up to expectations. I can take great pains. I have to rack my brains to find ways to read the words on the blackboard: with my eyes, yawning (because I found that I could read the words clearly when I opened my eyes once in tears), asking my classmates next to me what the words were on the blackboard, and so on. I am full of bitter water here! Because I am one of the tallest male compatriots in my class, because I am tall, I am naturally ranked last by the teacher, and I can't change my seat in the front row. Being tall has become a burden to me, so be it! Who let our Prime Minister kick him in the stomach? In addition, as long as I love my eyes, it doesn't matter to be in the last row! There is an old saying that a prime minister can sail in his stomach and a general can race horses on his head. Also, when I do my homework, my head is too low. Usually my mother yells at me to look up. It's also because of Ben.

5. Research report on myopia composition 1. Question proposition Many students in our class are nearsighted. They often say: "Wearing glasses is learning!" However, I just don't understand why they are nearsighted. How many students in our class are nearsighted? So, I made a survey with questions.

Second, the survey method 1, consult relevant books, and ask doctors to understand how ordinary people are nearsighted. 2. Investigate and ask classmates how they are nearsighted.

Find out how many people in Class One are nearsighted through various channels. Third, the aspects involved in the investigation and information channels. The specific content of the book is the main cause of myopia. Read books in places where the light is too strong or too weak; The number of nearsighted people who watch TV or computer for a long time is close to 30% in China, while there are 1 person and 18 people in our class who are nearsighted.

Doctors say that the harm of myopia will affect intellectual development, physical health, study and even blindness. Read books online to prevent myopia. Do more eye exercises, take an active part in physical exercise, and look far away every once in a while.

Conclusion 1 The main causes of myopia are: (1) Watching TV too close; (2) Watching TV for too long; (3) The picture density of TV is too deep; (4) Incorrect posture when writing homework; (5) reading in the sun with too strong light; (6) reading in weak light; (7) Sitting in front of a computer or TV for a long time; (8) unreasonable diet; (9) Reading in the carriage (10) is a genetic factor. 2. Myopia has many hazards.

(1) will affect intellectual development: 90% of people's acquisition of foreign information is done through their eyes. The intellectual development of teenagers can not be separated from the outside world.

(2) Complications: With the deepening of myopia, it will cause serious complications such as retinal detachment, glaucoma and vitreous deformation, and even lead to blindness and lifelong regret. (3) Influence on health: Wearing glasses restricts some sports activities and makes the body develop slowly.

Not everyone will be nearsighted. In fact, myopia can be prevented, but we should do the following: (1) Take an active part in physical exercise (2) Look into the distance once every once in a while (3) Don't read or write in a place with concentrated sunlight and dim light (4) Don't walk and read by car (5) Do eye exercises regularly (6) Don't read and write too close to the book (7).

When my mother mentioned my myopia, she began to sigh: "When I was a child, your eyes were so good, so bright, so bright and so dark, and it was bottomless. People knew what was the purest in the world. But now ah ┅ ┅ "seems to have lost a big baby.

Also blame my eyes for disappointing. But now, my eyes are not as bright as before, and they are a little less shiny. But, more mature. My eyes seem to be lovers' eyes-one eye has good eyesight and the other eye has a little poor eyesight. In class, sometimes I can't see the words written on the blackboard clearly because my eyes don't live up to expectations. I can take great pains. I have to rack my brains to find ways to read the words on the blackboard: with my eyes, yawning (because I found that I could read the words clearly when I opened my eyes once in tears), asking my classmates next to me what the words were on the blackboard, and so on. I am full of bitter water here! Because I am one of the tallest male compatriots in my class, because I am tall, I am naturally ranked last by the teacher, and I can't change my seat in the front row. Being tall has become a burden to me, so be it! Who let our Prime Minister kick him in the stomach? In addition, as long as I love my eyes, it doesn't matter to be in the last row! There is an old saying that a prime minister can sail in his stomach and a general can race horses on his head. Also, when I do my homework, my head is too low. Usually my mother yells at me to look up.

Also because I am a bookworm who loves books extremely, no, little bookworm. Hehe, I see it very dark. It would be amazing if I didn't read it. It usually takes two or three hours at a glance. When you meet a good book, you can't wait to open it and read it, hee hee. My reading posture is varied! Some are lying in bed watching, some are leaning against a big tree watching, some are walking, some are watching when the lights are dim, and so on.

How happy I was then. You can read books and play computer games at will, and you don't have to be afraid of being respected by the Jade Emperor (my mother) standing in the study, with a straight face, as if your face was covered with a layer of severe frost, and your mouth was like a machine gun. If you are trained, you will be ejected like a bullet. Haha, fortunately, I have no such experience.

However, the good times did not last long.

About nine months later, I had a physical examination. My eyesight has always been good, but I am nearsighted! When my trembling hand stretched out the "imperial edict", my mother's angelic face gradually turned into a dark cloud, and then (I dare not say it again, it was terrible)

In short, myopia is very bad. How I wish I was no longer nearsighted!

7. A 300-word report on myopia of primary school students.

First of all, this question:

Many students in our class have put on glasses one after another. How many people are nearsighted? Why are they nearsighted again? I made a survey with other students.

Two. Investigation method:

1. Consult related books to find out how ordinary people are nearsighted.

2. Investigate and ask classmates how they are nearsighted.

Three. Investigation and data collation:

The specific contents of all aspects involved in information channels

The causes of book myopia are too close to the eyes, too long use of eyes, too strong or too weak lighting, reading while driving or walking, and incorrect posture. ...

At present, the incidence of myopia in China is 33%, and the number of myopia in China has reached nearly 400 million, which is 22% 1.5 times of the world average. China is one of the countries with the highest incidence of myopia in the world.

According to the degree of myopia, the harm of network myopia can be divided into four categories: mild, moderate, high and ultra-high myopia. Mild myopia is generally below 300 degrees. At this time, many myopia are pseudomyopia and mixed myopia. Parents should focus on preventing myopia from developing to a high level. Once moderate myopia is out of control, developing into high myopia (above 600 degrees) will bring a series of problems: inconvenience in daily life, limited entrance to school, joining the army and working, and eye diseases passed on to the next generation. Once high myopia is not controlled, it will develop into ultra-high myopia (1000 degrees or more), and the retina may fall off at any time. ...

…… …… ……

Four. conclusion

1. Generally speaking, the homework burden of most students is very heavy, and it increases with the growth of grades.

2. No matter what grade you do your homework, you don't have a good rest for your eyes; The rest time at school once again shows a trend of decreasing with the increase of grade.

3. Anti-fatigue eye drops and eye exercises have therapeutic effects on eyes, but they have not attracted the attention of students.

Although there are many more people who are nearsighted than those who are not, people who don't wear glasses still account for a considerable proportion. This shows that students do not pay enough attention to myopia.

5. Other factors, such as incorrect posture and improper use of eyes, can be overcome and corrected; For example, if the light is too dim or too strong, we can adjust it. We can try our best to avoid improper protection and medication.
