How to write a 300 word myopia research report for elementary school students

Dad is addicted to smoking.

My dad is a teacher, and since we moved into the new house, I found out that my dad smoked too much, and I secretly made a report.

On May 12, there were many people smoking a lot of cigarettes. May.

A sample report on myopia among primary school students is as follows:

1. Ask questions.

Although very few of my classmates wear glasses, many of them are short-sighted, and if you sit back a little, you can't see what the teacher shows on the blackboard or on the big screen. So I investigated the main causes of myopia in elementary school students.

2. Analyze the problem.

Most students usually do not pay attention to the protection of their eyes to cause myopia, and the typical causes of myopia are:

1. Watching TV for too long.

2. Playing with the computer for a long time.

3. Reading books under light that is too strong or too weak**Annual survey report on myopia of primary school students**Annual survey report on myopia of primary school students.

4. Genetic factors.

5. Unreasonable diet.

6. Don't do eye exercises seriously.

3. Draw conclusions.

In recent years, more and more students in our class wear glasses, and the number of myopia is also increasing.

Fourth, measures. 1. When reading, you should sit in a correct posture and have sufficient light.

2. Try to surf the Internet as little as possible, watch TV less, and play game consoles as much as possible.

3. Don't eat partiality and eat less spicy food.

4. Don't read while riding or walking, and don't lie down to read.

Detailed Interpretation:

A survey report is an article that reflects the results of an investigation and research on a certain issue, an event or an aspect of the situation. It can be published in newspapers and periodicals, and it can also be used as a basis or reference for leading organs to handle problems and formulate policies.

The investigation report is a powerful way to propagate materialism and dialectics and adhere to the ideological line of seeking truth from facts, and has always been valued by proletarian revolutionaries.

Compared with correspondence, both have a large amount of factual material, and the narrative of the facts is relatively complete; However, the newsletter is often written about a series of events, with a vivid portrayal and detailed description, and the theme is expressed through vivid examples and touching images, while the investigative report focuses on the use of facts to illustrate the problem of hail hunger, and its theme is directly expressed by the author.

The study of myopia is written as follows:

1. Question raised: The latest data from the National Student Physical Health Survey show that the incidence of myopia among primary school students in China is that of middle school students and high school students. Because of this, the prevention and treatment of myopia in children and adolescents has become more and more concerned by students, parents and society.

Why are more and more students suffering from myopia? What is the student's eye that causes He Tuanlu to be short-sighted? In order to understand the myopia of primary school students and the related factors that cause myopia, our group conducted a survey on the myopia of students in our class.

2. Survey Method: Check the information on the Internet to understand what myopia is and the causes of myopia. Investigate and visit students to understand the study and living habits of myopic students.

Consult books on the dangers of myopia and how to prevent it. To investigate the myopia status and myopia ratio of students in the class.

3. Investigation and data collation: There are 56 students in this class, and the number of myopia is 22, accounting for two-fifths of all students, which is an upward trend compared with last year.

4. Conclusion: The myopia rate of adolescents is increasing year by year, which is inseparable from the heavy learning tasks of students and the increasingly developed social life. Myopia can be prevented, and it is necessary to achieve the "five dos" and "three don'ts":

Fifth, we should "develop good reading and writing habits, reduce continuous study time, and do eye exercises every day: the learning environment should be reasonable and bright; Pay attention to a balanced diet and spend more outdoor activities! Have your vision checked regularly.

Three don'ts": do not raise or infiltrate into the habit of reading on your stomach, lying down, walking, and riding in the car: do not read in dim light or in strong sunlight: do not read with a flashlight in the bed.

1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia.

Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

9. Regularly go to the eye hospital to check the eyesight, and if it is found, it should be corrected in time to prevent the progression of myopia.

10. Eat less sweets. Because sugar needs a lot of vitamin B1 to metabolize in the body, if you consume too much sugar, vitamin B1 will appear insufficient. Vitamin B1 deficiency can affect the growth and development of the optic nerve, leading to vision loss.

Excessive intake of sugar will also reduce the calcium in the body, weaken the elasticity of the eyeball, and promote the development of myopia.
