8 silkworm investigation reports

Silkworm survey report 1

Survey report on typos in 20xx

1. Purpose of survey: We usually read and read Newspapers, letters, and compositions are all inseparable from Chinese characters. We have to come into contact with Chinese characters every day in our lives. But how many people can use it correctly? Let us go to the streets and alleys together, look for typos, and do our best to purify the language of the motherland!

2. Scope of investigation: shop names in streets and alleys or Shop sign.

3. Investigation method: Divide into two teams to investigate separately, and take pictures of typos seen on the streets with cameras.

4. Investigator: .............

5. Investigation time: ............. ............

6. Survey results: Please see some of the pictures we collected

7. Survey analysis:

(1) Writing some words in traditional Chinese for the sake of appearance is not conducive to communication in people's lives. (Fresh eggs in Figure 1)

(2) Some text variations for children to attract people are misleading to children who are new to text. (The child in Figure 4)

(3) The character Yizhai is arbitrarily simplified for convenience, which brings inconvenience to people’s lives. (Opposite in Figure 5)

(4) Misinterpretation of idioms, unconventional use of Chinese characters, and very unserious use of Chinese characters. (The perfect world in Figure 2 and the world in Figure 3)

8. Suggestions and measures:

(1) Use television, newspapers, slogans and other media to vigorously publicize and enhance people’s correct use of Awareness of the motherland’s spoken and written language.

(2) It is hoped that relevant departments will remove and replace substandard store names or signboards.

(3) It is hoped that relevant departments will carry out effective supervision and prevent irregular Chinese characters from appearing in public places.

?Teacher Yang’s words

Writing an investigation report is different from ordinary narratives. It has certain format requirements and must be based on practice, so it is useful for primary school students. A certain level of difficulty. Hua Ziwei can start with typos on the street. The incision is small, but the investigation is very meaningful. (Investigation Report) Several elements of the investigation report are complete and organized, clear at a glance, and the ideas are clear. Especially through the picture display, it effectively illustrates the commonness and harm of typos, which is novel and effective.

However, Teacher Yang still has two suggestions:

1. Judging from the content and scope of the investigation, the author obviously focused this investigation on street typos. If compared The title is "Investigation Report on Typos of Chinese Characters", so the breadth of the investigation is not enough. Therefore, it is recommended to change the title to "Investigative Report on Street Typos", which is correct.

2. If the results of the survey can be reported in the form of data first, and then the typos on the street can be displayed in the form of pictures, it will be more convincing, enhance the depth and credibility of the survey, and improve the accuracy of the survey.

Silkworm Survey Report Part 2

Foreword:

1. Purpose of Survey: In order to create a green campus, further enhance environmental awareness and publicize environmental knowledge,* **To build a green home, we hereby launch this survey.

2. Survey objects: all students in our school.

3. Survey method: Random sampling method was used to survey the students of our school. The number of people surveyed was 525.

3. Survey location and time: Survey activities will be carried out in front of our school’s library, dining hall, student dormitories and other places. June 6, 2019 from 4:30 pm to 6:00 pm.

Text: In order to understand the depth of environmental awareness of college students in our school, so as to improve the environmental awareness of students in our school.

In this investigation, our investigation team found that there are some problems in our school. The main reason is that students in our school know some environmental protection knowledge, but they do not do what they should do.

Such as excessive use of disposable chopsticks, lunch boxes and plastic bags for packaging. The main reason why students in our school overuse plastic bags for packaging is that our students’ environmental awareness is not deep enough. Our school has not yet conducted lectures or courses on environmental protection knowledge. According to the survey, 38% of the students got their environmental knowledge from TV, radio, and movies as their main sources; 28% got it from newspapers and magazines, and less than 8% said it came from school courses. In a survey of the environmental problems existing in our school, 68 students knew that disposable chopsticks, lunch boxes and plastic bags were overused, followed by waste of water and electricity resources and destruction of flowers, plants and trees, accounting for 16 each. These issues are major environmental issues in our school. Regarding the issues of wasting water and electricity resources and destroying flowers, plants and trees, 16 students each said that environmental issues are also very serious. As our country's energy resources continue to decrease and trees are cut down indiscriminately, sandstorms worsen. Some of our students are still wasting water and electricity resources and destroying flowers, plants and trees. It can be seen from our monthly overpayment of water and electricity bills that students in our school are still wasting water and electricity resources. Packing with plastic bags is a serious environmental problem in our school. We overuse and create a lot of plastic waste, which is harmful to our health. Plastic bags are difficult to break down and cause damage to our environment. We need to realize that packing in plastic bags is harmful to our health. Some bad substances will be brought into your stomach when you eat, causing poisoning or disease. The environment of our school is pretty good, but if we don’t pay attention to environmental protection and hygiene and make garbage everywhere, then the environment of our school will get worse and worse! We will not have a good learning environment! Therefore, we must start from three aspects Start with: First, start from yourself, second, start with small things, third, develop environmental awareness and good behavioral habits of saving resources and caring for the environment from an early age.

The environmental problems in our school are caused by our bad habits. For example, students in our school have the habit of packing and wasting water and electricity. If we continue like this, we will become environmental destroyers and our country will not be able to sustain its development. In the survey, 70% of the students agreed that they can use chopsticks and plastic bags once, but reduce their use. In order to solve the environmental problems of our school, it is not only a matter of the school, but also a matter of everyone in our school.

I hope that everyone’s environmental awareness will be enhanced and they will take action to protect our campus; and that our school will carry out more environmental protection activities to awaken their environmental awareness. In the future, our hospital will work hard to promote environmental protection and do a good job in environmental protection work.

IV. Investigation content

On the evening of the 25th, I came to the Qujiang River and saw that the water was very turbid and smelled a bit after walking through it. On the afternoon of the 26th, I came to the Qujiang River again. It had just rained and it was much better than on the 25th. There was no smell or turbidity. I also interviewed a fisherman who has been fishing for more than 20 years. He said: "The water was very good before 1975, but it got worse after 1980. It is getting better now. It is much better than in the 1990s. Mainly because of that A dam has been built nearby, so big fish can no longer be caught. The fish are small and there are few fish. I only have a few dozen yuan a day. "I observed that there are water hyacinths in the Qujiang River, as shown in the picture below: There are also floating objects, as shown in the picture below: And on the edge, maybe people just threw it away and landed on the edge. There are many pipes for discharging sewage in the river!

Experiment:

(1) I scooped some water back home and used the same napkin to mix it with tap water. Filter comparison. The napkins after filtering tap water are colorless, and the napkins after filtering river water are light gray.

(2) I took two small goldfish and put them into the river water and tap water respectively. After a few days, I found that the goldfish in the river were trying to turn their stomachs upside down and were not used to the life here. The goldfish in tap water are better and free. It can be seen that the river water is dirty but the tap water is clean.

5. Investigation experience

I hope that through my investigation report, I can teach some people a lesson so that some people will stop throwing garbage after reading it. Protect Qujiang, protect every river, let us start from now, start from small things!

Silkworm Survey Report Part 5

Our county is located in the upper reaches of the Nen River, with ground water sources within the territory It is rich in water resources, with one river, three rivers and 49 streams, all of which are the Nenjiang River system. The total water resource reserve is 8.72 billion cubic meters, of which 93.4% is surface water and 6.6% is groundwater.

The total length of the Nenjiang River is 1,370 kilometers, and the length of the main stream in our county is 404 kilometers, accounting for 29.5 of the total length.

The waters, meadows, and woodlands east of the main stream of the Nen River in our county constitute the typical wetland ecosystem, forest ecosystem, and grassland ecosystem in the upper reaches of the Nen River. These three systems are the green barrier in the northwest of our province. It is also an important water source conservation area, key water and soil conservation protection area and supervision area in the western region of our province. It plays an important role in maintaining the ecological balance of the Nenjiang River Basin and the northwest of our province, mitigating natural disasters, and ensuring the water quality and quantity of the Songhua River.

As the upper reaches of the Nenjiang River, the ecological environment of our county directly affects the water quality and quantity of the Nenjiang River, which in turn affects the water quality assurance and water supply of the Nilji Reservoir, the middle and lower reaches of the Nenjiang River and the Songhua River. In recent years, with the rapid development of urban and rural construction and economy, the county's ecological environment has been damaged by unreasonable development. The groundwater level has dropped, swamps are generally short of water, and the area of ??forests, grasslands, and wetlands has decreased. The regional ecological environment has become very fragile. . As the discharge of industrial wastewater and domestic sewage continues to increase, although certain results have been achieved in industrial wastewater treatment through "one control and two standards", the total amount of wastewater discharge has not decreased, especially the non-point source pollution caused by domestic sewage. The lack of sewage treatment facilities is getting worse. According to monitoring, water pollution levels during the dry season have reached Category Five water bodies. Therefore, it is urgent to control water pollution within the jurisdiction, especially in urban areas.

1. Current status of water environment quality and causes of pollution within the jurisdiction

(1) Current status of water environment quality

1. Overall status of surface water environmental quality: surface waters The environmental quality has deteriorated sharply, and the watershed has become seriously polluted. The entire network has been changing from north to south, and has been at a disadvantage.

In accordance with the requirements of the national surface water environmental quality standards, the surface water quality of our county should meet the functions of Class III water bodies and strive to be controlled within Class II water body standards. The water quality should meet the requirements of Class II protected areas for centralized drinking water sources, general fish reserves and Swimming area features. Comparative analysis of national standards and surface water monitoring data from monitoring stations in our county in recent years shows that the surface water quality in urban sections of the main stream of the Nen River in our county exceeds the four-category standard limit in the national standard, and in severe cases reaches the five-category standard limit, which is only applicable It can be used in general industrial water and recreational water areas where the human body is not in direct contact. There are two drainage outlets in the town, of which the oxidation pond drainage outlet in the west of the city is a combined rainwater and sewage outlet. The monitoring results in June 20xx were: suspended solids exceeded the standard by 13 times, chemical oxygen demand exceeded the standard by 18 times, and biochemical oxygen demand exceeded the standard by 51 times; The Lama River drainage outlet is the drainage outlet that receives the main industrial wastewater in the county. The monitoring results are: suspended solids meet the standard, chemical oxygen demand exceeds the standard by 7 mg per liter, biochemical oxygen demand exceeds the standard by 2 times, and ammonia nitrogen exceeds the standard by 10 times. The other two sections of the main stream of the Nenjiang River in the jurisdiction have Category III water quality, with ammonia nitrogen, permanganate index, transparency, suspended solids and other items seriously exceeding standards.

The water quality of each tributary of the Nenjiang River system is even more worrying. Among them, the first-level tributary Woli River has a water quality of Category 4, the Menglu River has a water quality of Category 4, the Wodu River has a water quality of more than Category 5; the second-level tributary Loach has a water quality of Category 4. The river's water quality exceeds category five.

2. Groundwater environmental conditions: Groundwater bodies in urban areas are polluted. Due to the increasing accumulation of pollution, groundwater in some areas has become undrinkable. The water level in the southern part of the city has dropped. The water quality of the water supply source in the northeast is turbid, astringent, and has a peculiar smell. The drinking water of some residents in family buildings has flocculent sediments and peculiar smell. The drinking water of more than 170 residents in the southwest has been contaminated. The quality of groundwater near the garbage dump has deteriorated.

(2) Causes of water pollution

1. Domestic sewage from urban residents. The urban area generates 3.6 million tons of domestic sewage annually. Since our county does not have sewage treatment facilities, pollutants pass through the urban drainage system and are directly poured into the main stream of the Nen River from the sewage outlet in the west of the city, worsening the ecological environment of the water body.

2. Industrial wastewater. The Lama River in the town is a centralized discharge point for industrial wastewater and Tiedong domestic sewage. Although it has passed the "one control and two standards" acceptance, there are still 251,000 tons of sewage discharged into the mouth of the Lama River every year. In addition, each tributary has the Woli River receiving 100,000 tons of mining wastewater every year; the Loach River and Menlu River receiving 1.01 million tons of gold mining wastewater every year.

3. Soil and water loss. Due to barbaric activities such as deforestation, quarrying, sand mining in rivers, and illegal gold mining in various tributaries in the past few years, natural vegetation has been destroyed, ecological regulation capabilities have declined, and soil erosion has been aggravated. At present, the county's water and soil erosion area is 307,800 hectares, which is 30% of the county's operating area. The soil organic matter has dropped by 2%. The lost water and soil has entered the Nenjiang River system, causing the river's biochemical oxygen demand, chemical oxygen demand and ammonia nitrogen to seriously exceed standards.

4. Leakage from seepage wells, public toilets, drainage pipelines and some septic tanks in urban areas directly pollutes groundwater and leads to the deterioration of water bodies.

2. Measures taken by our county to prevent the deterioration of water quality

1. Implement total volume control, actively control key pollution sources, and consolidate the results of compliance with standards. In order to protect water quality and prevent water quality deterioration, while strengthening environmental management of construction projects, our county has focused on the treatment of key pollution sources and the consolidation of compliance with standards. By carrying out pollutant discharge declaration and registration, issuing pollutant discharge licenses, adopting centralized control and time-limited treatment and other measures, industrial and mining enterprises that discharge pollutants are strictly managed, and the water quality, water quantity, type and the setting of sewage outlets of water pollution sources are identified. Here, Based on the allocation of total control indicators, the industrial wastewater pollution in the jurisdiction is controlled within a certain range.

2. Implement ecological protection projects. Generally speaking, the industrial scale of our county is small, the economic type is mainly agricultural, and industrial pollution has little impact on water quality.

Therefore, the county government regards managing the ecological environment in the basin as the key to protecting water quality and quantity and achieving sustainable economic development. It has successively issued the "Ecological County Construction Plan", "Ecological Demonstration Construction Plan", and "Protection of Ecological Functions in the Upper Nenjiang River Basin". District Construction Plan" and "Nen River East Bank Wetland Ecosystem Protection Project Plan", through the organization and implementation of a series of plans and projects, have provided good ecological conditions for the restoration and protection of the natural environment of the Nen River Basin in the county.

3. Implement the promotion strategy of key engineering projects. In recent years, our county has incorporated water pollution prevention and control work into the county's national economic and social development plan and annual plan. It determines key water pollution prevention and control projects every year and promotes the improvement of water environment management. In order to protect the water quality of the main stream of the Nen River, construction projects such as Beijiang Park, urban drainage pipe network, and sugar factory oxidation pond pumping station have been organized and implemented. These infrastructures have played an important role in effectively improving the water environment.

4. Strengthen the construction of water environment monitoring network. In order to protect the water environment, our county has formulated the "Water Environment Function Protection Plan", which divides the main stream of the Nenjiang River in the jurisdiction into four functional protection zones. According to different functional divisions, three monitoring points have been set up in comparison with the three sections. Over the past few years, through surveillance monitoring of 10 projects, 150 effective monitoring data have been obtained every year, which timely, accurately and comprehensively reflects the water quality conditions in dry, flat and wet periods, and provides water quality information to the Nenjiang River Water System Office and relevant departments. While establishing and improving the watershed monitoring network within the jurisdiction and optimizing the monitoring distribution, a provincial-level ecological monitoring station at the source of the Nenjiang River was established.

5. Carry out water pollution prevention and control work in accordance with the law. In order to effectively prevent and control water pollution and avoid water pollution accidents, our county has taken compulsory measures in accordance with relevant laws and regulations to comprehensively clean up the units that caused water pollution, so that the penalties and rectifications that should be punished will never be punished. Appeasement. As the main placer gold mining area, in order to standardize the order of placer gold mining, the county government organizes relevant departments every year to clean up and rectify illegal gold mining boats in the upper reaches of the main stream and tributaries, and strictly carry out unlicensed mining, cross-border mining, and gold mining boats that damage water bodies. Investigate and punish various illegal operations in accordance with the law. In addition, in response to the pollution incident of the Liuyuan Water Plant in the upper reaches of the Nenjiang River in Qiqihar City, our county organized relevant departments to conduct a comprehensive investigation. At the same time, in order to keep abreast of the water pollution status of the river, an environmental protection 110 linkage team and an environmental protection volunteer team were formed. A public participation and supervision system for water pollution has been established and improved.

3. Rely on the project to speed up the process of water pollution prevention and control

As the water source and main conservation area of ??the Nen River, our county is bound to protect the Nen River water system. In terms of water environment management and urban water environment improvement, we should seize the favorable opportunity when the country revitalizes the Northeast regional economy, increase investment in protecting the Songhua River,

protect the Mother River, and ensure the water quality safety of the Nilji Reservoir area. Make good use of the location advantage, use the construction of the ecological functional protection zone in the upper reaches of the Nenjiang River as a carrier, rely on environmental protection projects, actively strive for special funds from superiors, and take advantage of the situation

to accelerate the process of water pollution prevention and control.

The first is the construction project of the ecological function protection zone in the upper reaches of the Nenjiang River. The "Plan for the Construction of Ecological Functional Reserves in the Upper Nenjiang River Basin" has been compiled. The "Plan" divides the county's ecological functional areas into three communities for planning and construction respectively, and implements three projects of water conservation, mountain control, and famine control to protect The watersheds mainly conserve water sources, control water and soil erosion, carry out watershed vegetation restoration and reconstruction projects, focus on building water source conservation forests and soil and water conservation forests, and establish a complete watershed protection system. The estimated implementation cost of key project planning is 82.5 million yuan.

The second is the gold mine ecological environment restoration project. Over the years, placer gold mining has caused ecological environment damage and water pollution in the main stream and tributaries of the Nen River Basin. According to provincial and municipal requirements, all placer gold mining will be banned throughout the province in 20xx. The restoration of the gold mine's ecological environment will be the focus of our county's land remediation work in the future. In the ecological environment restoration plan for the placer gold over-mining area, the land department has identified the Sisge placer gold over-mining area as a key management project in accordance with the principle of overall planning and step-by-step implementation. The project has been submitted to the Municipal Planning Commission for approval, with a total investment of 7.752 million yuan.

The third is sewage treatment and drainage pipe network construction projects. In order to completely solve the problem of urban sewage pollution, our county proposed to build a Nenjiang Town sewage treatment plant in 20xx. It will start operation in 20xx. Its feasibility study report has been approved by the Provincial Planning Commission. This project should be started as soon as possible to improve the water quality environment of the Nenjiang River Basin.

The fourth is the “East-to-West Waste Discharge” project. The main industrial zone east of the railway in our county is currently discharged into the Lama River. The Lama River handles 250,000 tons of industrial wastewater every year. With the development of industry, the discharge of industrial wastewater will continue to increase. The Lama River passes through Dongcheng District and discharges directly into the main stream of the Nen River. It is the second sewage outlet in the town. The Lama River should be comprehensively managed, and pipelines should be laid at the same time to implement "east sewage discharge to the west" so that industrial wastewater can be discharged into the oxidation pond in the west of the city through the pipe network and be treated centrally after the sewage treatment plant is completed. It is estimated that the pipeline pump station project requires an investment of more than 10 million yuan.

The fifth is the harmless disposal project of garbage. For many years, there has been no formal garbage treatment plant in our county. The existing garbage dump site is an abandoned pit formed by taking soil for brick making. The bottom is not leakproof and is close to residential areas. At present, all 400 tons of urban domestic waste, biochemical waste and medical waste produced per day are piled here. In order to control water environment pollution, our county is currently in urgent need of building a harmless garbage treatment plant that is leakproof and has the function of medical waste disposal.

Silkworm Survey Report Part 6

1. Question raised:

As we grow older, more and more students in our class are myopic. Put on glasses. I'm curious, how many people in our class are myopic? How did they cause myopia? So, I did my research.

2. Investigation method:

1. Read relevant books to understand how ordinary people become myopic.

2. Survey and ask classmates to find out how they become short-sighted.

3. Through various channels, we can understand the number of myopia in our class.

3. Investigation and data collection:

There are 46 people in my class, about 12 of whom are myopic.

Myopia rate among students:

Primary school students: 22.7. Junior high school students: 55.8. High school students: 70.3. College students: 80.

By looking up the myopia rate among students, we found that the rate among primary school students to college students is constantly increasing. It can be seen that as people age, their eyesight continues to decline. There are many causes of myopia. According to my guess, the causes of myopia are: genetics, too long time watching computers, reading, excessive stress, lack of calcium, lack of sleep, excessive intake of refined sugar, etc. are all the main causes of myopia.

4. Conclusion

Through the analysis of the data, I found that anti-fatigue eye drops and eye exercises both have a therapeutic effect on the eyes, but they have not attracted much attention from the students. Although the number of people with myopia is much higher than the number of people without myopia, a considerable proportion of people do not wear glasses. This shows that students do not pay enough attention to the problem of myopia!

I make the following suggestions:

1. Keep looking into the distance every day, insist on doing eye exercises and inter-class exercises, and actively participate in sports activities and strengthen exercise.

2. There should be sufficient light when studying. Do not read or write under insufficient light, dazzling sunlight or strong lights.

3. Do not sleep on the bed, in the bus or read a book while walking. Don't read or write on the table with your head tilted to one side. Develop good eye habits to prevent eye fatigue.

4. Don’t watch TV or play computer games too much or for too long. Not too close, not too far.

5. Eat more fresh fruits and vegetables. Don’t be picky about food, eat less spicy food, and eat more food containing vitamin C, vitamin A, and D.

No matter where you are, you must remember to protect your eyesight and take care of your eyes, because "eyes are the windows to the soul." If you lose your eyes, you will not be able to see the colorful world.

Let beautiful eyes accompany us throughout our lives!

Silkworm Survey Report Part 7

Working outside has become an important income for farmers. In the past 20 years, the floating population has been increasing. The floating population is mainly young and middle-aged laborers who migrate from rural areas to cities. The young and middle-aged labor force accounts for about 70% of the total floating population. As a result, in many areas where the migrant population is concentrated, the problem of "left-behind families" has generally occurred. Currently, among the many issues related to left-behind families, the issues of "left-behind elderly people", "left-behind wives", and especially "left-behind children" have attracted widespread social attention.

Once the parents of these left-behind children go out, they are busy working all day, and most of them have no time and energy to care about their children's studies, let alone their children's inner confusions, needs, and interests. Even if some people want to care, due to financial and other conditions, they are unable to call their children more often or return home to see their children frequently. In addition, the fact that one spouse has gone out to work for a long time has also caused the breakdown of many rural families and affected the healthy development of children. Due to the lack of family life and parental education, left-behind children are bound to have the following problems:

1. Lack of guidance in studies. Left-behind students often fail to complete homework, play truant, and drop out of school. The majority of students have average or poor grades. What deserves special attention is that some left-behind students are tired of studying, forming a vicious circle.

2. Lack of care in life. The livelihood of left-behind children mainly relies on money sent home by their migrant parents or temporary guardians at home. The lives of most left-behind children in rural areas are relatively poor, and some even have no support and their lives are extremely difficult. Some left-behind children are seriously undernourished and their health has been greatly damaged.

3. Lack of warmth in family relationships. The parents (or one party) of left-behind children are not around the children and lack the care they deserve. Parents work outside the home, and most of them are physically and mentally exhausted. They have less contact with their families, are separated from their children, lack communication and communication with their children, and lose family ties. In the survey, more than 90% of left-behind students generally felt a sense of loss and loneliness due to the absence of their parents. Some parents have been away from home for many years and never come home. They also have no electricity or credit, making it impossible to talk about the existence of family ties.

4. Lack of psychological help. Due to defects in family ties, left-behind children are unwilling to have contact with the outside world or have too little contact with the outside world. Most of them show inner closedness, emotional indifference, withdrawn behavior, lack of love and initiative in communication, and indifference to the collective. Most left-behind children in rural areas have mild or severe psychological disorders, poor living and hygiene habits, a strong sense of inferiority, and poor self-care ability.

5. Lack of moral education. Left-behind children often grow up in an environment that is laissez-faire and lacking in emotions, and their moral and character education cannot be properly trained. Surveys show that many children are addicted to bad habits, lack moral restraint, and cannot withstand the temptation of bad things from the outside world. Some have bad tempers, are impulsive and irritable, and often escalate trivial matters into fights.

6. Lack of self-control in behavior. Minors are in a critical period of growth and development. When their parents are away, they cannot enjoy the correct guidance and help from their parents in terms of ideological understanding and values. Some bad cultures and deviant behaviors are easily accepted by them who lack correct judgment. They gradually develop many bad behaviors. Some are addicted to the Internet and cannot extricate themselves; some are lazy and commit petty theft; some often stay away from home and get into fights.

7. Lack of security guarantee. Left-behind children face safety problems in playing, working, and living. Safety accidents often occur because of inadequate guardians or the absence of temporary guardians.

Silkworm Survey Report Part 8

Studying and Living Habits of Myopic Students

Some students are too close to books when writing: they use their eyes for a long time without taking a break: Reading in an environment with too strong or too weak light: watching TV for a long time, playing computer without taking a break, etc.

Check out relevant books

The dangers and prevention methods of myopia

Myopia will affect the physical and mental health of children. Myopia in children will have a certain impact on their education, employment, and life when they grow up.

Protect your eyes, prevent myopia, pay attention to eye hygiene, and don't let your eyes tire too much.

Myopia status and proportion of myopia in this class *** There are 42 students in this class, of which 21 are myopic, accounting for 1/2 of all students. Compared with last year, this is an upward trend.

1. Conclusion

1. The myopia rate among teenagers is increasing year by year, which is inseparable from students' heavy learning tasks and increasingly developed social life.

2. Myopia can be prevented by following the "Five Musts" and "Three Don'ts":

"Five Musts":

(1 ) Develop good reading and writing habits;

(2) Reduce continuous study time and do eye exercises every day;

(3) The learning environment must be reasonable and well-lit;

(4) Pay attention to a balanced diet and engage in more outdoor activities;

(5) Check your eyesight regularly.

"Three Don'ts":

(1) Do not develop the habit of lying down, walking, or riding in a car to read;

(2) Do not read in Read under dim lights or under strong sunlight;

(3) Do not read under the covers with a flashlight.

Students, eyes are the windows to the soul. We must protect our eyes well so that they will always shine brightly!

Survey report on myopia among primary school students

1. Asking questions

Although few of our classmates wear glasses, there are many who have myopia. Just sit back a little and you won't be able to see what the teacher is showing on the blackboard or on the big screen. So I specifically investigated the main causes of myopia among primary school students.

2. Analysis of the problem

Most students develop myopia because they do not pay attention to protecting their eyes. Typical causes of myopia are:

1. Watching TV The time is too long

2. Playing on the computer for a long time.

3. Read under a light that is too strong or too weak.

4. Genetic factors.

5. Unreasonable diet.

6. Not doing eye exercises seriously

3. Drawing conclusions

In recent years, more and more students in our class wear glasses, and some of them are myopic. The number of people is also increasing

IV. Measures

1. When reading, sit in an upright posture and have sufficient light.
