Article 1:
With the continuous development and popularization of electronic information technology, computer networks have spread all over our lives. Computer teaching can create a certain language environment, give people direct, concrete and real feelings, thus stimulating students' interest in learning. The role of computer network can not be underestimated, it has played a very good role in broadening students' horizons, expanding their knowledge and enhancing their practical ability. However, according to incomplete statistics, the total number of netizens in China has exceeded 20 million at present, and the number of students surfing the Internet is increasing day by day, accounting for more than 20% of the total number of netizens. After many in-depth investigations, we found that 68% of middle school students play games online, 39% like literature and sports, 35% chat with friends, 26% send emails online, only 16% care about computer software, and 6% learn health knowledge and pay attention to news. It can be seen that most middle school students surf the Internet to play games, have fun and make friends. Network will have a great influence on middle school students' way of thinking, behavior, physical and mental health and values. We should not only see the advantages of the network, but also pay special attention to the disadvantages.
First of all, it affects the formation of new ideas and new consciousness. The network has the characteristics of large amount of information, fast propagation speed and wide influence range. A large amount of online information can really provide a good learning platform for middle school students, broaden their horizons and enrich their extracurricular life. However, online information has not been filtered, and any opinions can be freely published. Selfish and pragmatic western values, hedonism and decadent lifestyle of pursuing enjoyment will also come together. Because the concept consciousness of middle school students has not yet formed a relatively complete system and is not mature enough, if we accept such various online information in large quantities, it will inevitably affect the formation of new ideas and new consciousness of middle school students, and make them gradually accept western democracy and western culture, thus distorting our traditional moral norms and codes of conduct.
Secondly, it threatens students' physical and mental health. If middle school students surf the Internet for a long time, it will inevitably occupy the necessary time to participate in social activities and physical exercise, and it will also occupy the normal study time, which is not conducive to the improvement of social activities and physical health, and is also not conducive to learning scientific and cultural knowledge. Middle school students' period is the key period of physical and mental growth in life, and it is very important to develop good study and living habits for people's life. If you surf the Internet for a long time at this time, it will easily lead to physical fatigue and neurasthenia, leading to physical decline and bad mood, which will seriously affect the growth and development of all aspects of the body. In addition, visual network content can strengthen students' ability to accept reading, but it also weakens students' thinking ability. According to our survey, middle school students who have been obsessed with the Internet for a long time are obviously inferior to students who receive traditional education methods in calligraphy writing, analysis and criticism.
Third, it affects interpersonal communication in real society. Because the network has the characteristics of freedom, equality and virtual indirectness, middle school students who are in their youth are very active in their thinking activities, and they are very eager to get equal opportunities to communicate with adults. Virtual equal communication on the network can freely choose objects, which they can't do in real society, so middle school students are very willing to express their views and opinions on many issues online, especially some hot issues on campus and society that they care about. Through communication and discussion, we can reveal their true thoughts, and we can completely vent our inner happiness and pain here, so as to make up for the shortcomings in real life through virtual networks. Because middle school students' personality has not yet formed, if they only make friends online for a long time, their actual communication ability with social natural persons will be greatly reduced, because the freedom on the internet will give them an illusion that they can care about their own psychological feelings without caring about the changes in real life and the sufferings and joys of others, which is absolutely impossible in the real society.
Article 2:
First, investigate the problem.
Although middle school students' consumption and consumption concepts have gradually become independent, there are still many problems. Because of their age, they are rebellious and hesitant, and their consumption is gradually independent, but their economy is not independent. Schools should strengthen the education of students, promote simple lifestyles, guide moderate consumption and healthy consumption, and parents should cooperate with school education attentively, not blindly indulge, and grasp the degree. The society should also correct unhealthy trends and abnormal public opinion, standardize middle school students' consumption and consumption views, and put their consumption on the right track. This survey is based on the consumption status of eighth-grade students in Haitang Middle School, which can initially reflect the consumption status and problems of contemporary middle school students.
Second, the scope of investigation
Grade 8 students in xxx middle school
Third, the survey method and time
By random sampling, a questionnaire survey was conducted among 8 th grade students in Haitang Middle School 100. The method of questionnaire survey was adopted. Questionnaire 100, 94 valid questionnaires, and the completion rate reached 94%. The time is 65438+February 65438+June 6.
Fourth, the investigation and analysis
In the survey, 44.68% were boys and 55.32% were girls.
The analysis, investigation and statistics are as follows.
(A) the status quo of pocket money for junior high school students
According to the survey data, students with pocket money account for 86. 17% of the total number of people surveyed, while students without pocket money only account for 13.83%. Most of junior middle school students' monthly pocket money is below 50 yuan, accounting for 65.96% of the total number of respondents, 50- 100 yuan accounts for 20.2 1% of the total number of respondents,100-/50 yuan accounts for 5.32% of the total number of respondents, and 150 yuan or above accounts for 5.32% of the total number of respondents. So where does the pocket money of middle school students come from? Most of their pocket money comes from their parents, accounting for 78.72% of the total surveyed. Followed by grandparents and grandparents, accounting for 26.20% of the total number of people surveyed; Only 14.89% of the total number of people surveyed came from their own jobs. Others account for 20.2 1% of the total survey. At present, students are basically the only children in the family. Parents are almost obedient and loving to their children. Even if they scrimp and save, their children always have everything they need. Who doesn't want their children to have a better life? Some parents always put a few dollars in their pockets to buy snacks and school supplies before their children go to school. When children go out to play, they will also prepare some expenses for their children. These pocket money are also part of parents' investment in their children's growth. Only a few children in the family may have their daily lives arranged by their parents, so they don't need any pocket money. But these are relatively few families. So most students have pocket money, but junior high school students are still young and usually don't spend much. In addition, junior high school students' decision-making potential and action potential are relatively weak, so parents generally don't give their children too much money to control, only when they go out and go out for a long time.
Will be relatively "generous", generally give a few dollars at a time to meet daily expenses and daily fares. Therefore, most junior high school students' monthly pocket money is below that of 50 yuan. A small number of students who live with grandparents or other relatives often receive pocket money from them, which is also based on the care of the elders for the younger generation. A small number of students who expect to be "self-reliant" can improve their living conditions by working, and at the same time get in touch with society and enrich their social experience. However, middle school students are still relatively young, and there are not many parents who can agree to use their spare time to work. Most parents still love their children and can't bear to let them suffer.
(B) Middle school students pocket money consumption
(1) Middle school students' pocket money consumption
According to the survey data, although parents love their children, most of their pocket money is spent with friends, accounting for 64.89% of the total surveyed, 54.26% by themselves, 39.36% by parents and 30.85% by other circumstances. Where do they spend it as long as they want it?
(2) Three "flows" of middle school students' pocket money: buying books, saving money and buying snacks.
The survey results show that students who buy books with pocket money account for 38.30% of the total number of people surveyed; Savings account for 77.66% of the total number of people surveyed; Snacks and drinks accounted for 39.36% of the total survey, and the selection rate of these three uses was significantly higher than other uses. And those who play games (including some home computer games) account for 23.40% of the total number of people surveyed; Spending on sports accounts for 18.08% of the total number of respondents, and spending their own pocket money on clothes (including clothes and shoes) accounts for 19. 15% of the total number of respondents. Most parents think that books are spiritual nutrients for students' growth, and the cultural book market is also relatively prosperous at present, whether after class or in class; Entertainment, computer knowledge; Hobbies, literary novels and other books can be bought in the book market, so parents are also in favor of children buying books, always expecting their children to learn, so book consumption has become a major consumption direction of students' pocket money. Most of the books they bought were newspapers and magazines, followed by comics, accounting for 43.60% and 34.04% respectively. Most middle school students spend their pocket money on books, which is actually a manifestation of their cultural consumption. Many teenagers are full of longing for their future life, so many teenagers fill their spare time and spiritual needs through various books, which should attract parents' attention.
(C), middle school students' consumption patterns and consumption concepts
At present, students' after-school life has been enriched a lot, and the market economy has made the consumption field pervasive. Students who have no direct financial resources have also become the target group of many businesses. However, under the urging of parents, middle school students' consumption concept has been greatly improved, accounting for only 1.06%, buying when they see the right one, trusting their own eyes, saving money, accounting for 36. 17%, and making a good consumption plan, accounting for 32.97%. At this moment, the student economy is developing rapidly: grocery stores, stationery stores, bookstores and Internet cafes. Some commercial streets in the urban area have also set up specialty stores for teenagers' products, which is undoubtedly aimed at young students, and many well-known sports brands also regard this group as the key consumer. In such a big environment, the student consumption market has also been further started. However, when buying, middle school students will also start thinking. When economic conditions permit, 60.63% of the respondents can think of it, 28.7% have no opinion, 1 1.70% should not buy it, and only 7.45% will not buy it because of the high price. They should also consider the use and price of the goods, accounting for 69. 14% and 6 1.70% of the total number of people surveyed respectively. The factors they had to consider later accounted for 46.80% and 38.80% of the total number of people surveyed respectively. At this time, they buy when they think it is appropriate and when necessary, accounting for 46.8% of the total number of people surveyed respectively.
3.65438+ 09% of the total survey. This can prove that their consumption concept has been greatly improved and they will not blindly consume.
(D) Middle school students' post-consumption concept
In this survey, it is found that teenagers spend pocket money in a planned way, and they also know where their money goes. Self-system settlement and self-time settlement account for 44.68% and 27.60% of the total number of surveys respectively, while never and never account for only 13.83% and 1 1.70% of the total number of surveys respectively.
Verb (abbreviation of verb) survey results
At present, in the consumer market, the number of middle school students in China is as high as 73 million, and middle school students as a consumer group are gradually being valued. Although there is not as much spare time as college students, middle school students also have our unique consumption concept. On the one hand, we have academic pressure and are not independent economically. On the other hand, we have our own consumption needs. Sometimes, in order to get what we really want, we can spend time and try our best to achieve our goals. Therefore, it is very important to establish a correct consumption concept in the psychological development of middle school students. Nowadays, middle school students have begun to have independent consumption behavior. We usually have a fixed consumption fund (pocket money) every month, and we have regular independent purchase activities, which have an increasing impact on family consumption.
Investigation and suggestion on intransitive verbs
Investigating and analyzing the consumption psychology of middle school students is a necessary reference to help them establish a correct consumption view. The concept of domestic consumption is still relatively backward. Parents always expect to create a comfortable environment for their children and let them grow up under their own umbrella. Who doesn't expect their children to get ahead in the future, but don't be careless in education. It is not good to "pull out the seedlings to encourage them", and it is even more undesirable to be too "cautious"! We should always pay attention to the changes of children's psychological status, and vigorously publicize the virtues of the Chinese nation's hard work and self-improvement and the spirit of hard work and courage of contemporary advanced figures through various forms.
Article 3:
Investigation report on urban environmental pollution
Cities are the political, economic, cultural and scientific education centers of human society, with high economic activities and population density, and are facing enormous pressure on resources and environment. In 2004, there were 66 1 organic cities in China, and the land area of municipal districts only accounted for 6% of the total land area of the country. The population accounts for 4 1.7% of the total population in China.
The urbanization rate increased from 28% in 1993 to 4 1.7% in 2004, an increase of 13.7 percentage points. The contribution of cities to China's GDP is 65.5%. The level of urbanization has been continuously improved and entered a period of rapid growth. Cities occupy a very important position in the whole national economy. What is not widely known is that half of the top ten cities with the most serious environmental pollution in the world fall into the territory of China. What is even more shocking is that the area of China13 has experienced acid rain, half of the seven rivers in China have been seriously polluted, the residents of China14 have no clean drinking water source, and the urban people of13 have to breathe dirty air. Environmental pollution has also increased production costs, resulting in economic losses of 8% to 15% of the gross national product, and people's health costs are incalculable. In Beijing alone, 70% to 80% of cancer causes are related to the environment, especially lung cancer, which has become the first cause of death among residents. Cities are the product of the development of human social politeness in a certain historical period. Its emergence and development depend on the economic development and are also influenced by the superstructure. In recent decades, the rapid growth of urban population and rapid economic development have caused a series of environmental problems:
1. The water pollution problem is outstanding.
Due to the rapid growth of urban population and the rapid development of industry, excessive sewage is directly discharged into the water without proper treatment, causing serious damage to the water environment. Recently, water pollution in China has been increasing. More than 850 rivers with monitoring data 1200 in China are polluted. Among the seven major water systems, the Liaohe, Haihe and Huaihe rivers are seriously polluted. 1, among 38 urban river sections, 1, 33 river sections are polluted to varying degrees. Across the country, 78% of the river reaches are not suitable for drinking water sources, 50% of the groundwater is polluted, and many cities such as Xi and Beijing have also experienced water supply crises. It is estimated that the economic losses caused by pollution in China reach 40 billion yuan every year.
2. Urban air quality has deteriorated seriously.
With the rapid development of industry and transportation and the overuse of fossil fuels, dust, sulfur oxides, nitrogen oxides, carbon oxides, ozone and other substances are discharged into the atmosphere, which seriously deteriorates the air quality. China's air pollution belongs to "soot pollution", and the concentration of total suspended particulate matter in urban air in China generally exceeds the standard, with an average concentration of 309 μ g/m3; The concentration of sulfur dioxide is relatively high, and pollution in some cities is quite serious, with an average of 83 μ g/m3 in northern cities. Benxi, China, is also called "the city that can't be seen by satellite" because of the smog. However, excessive sulfides and nitrogen oxides in the atmosphere have caused acid rain in most parts of the country. The frequency of acid rain in Yibin, Changsha and other cities exceeds 90%, and the average PH value of rainfall in Changsha reaches 3.54. The arrival of acid rain not only destroyed the ecological environment, but also aggravated the corrosion and damage of buildings, railways and bridges, bringing huge losses to industry and agriculture. The greenhouse effect and ozone layer destruction caused by air pollution directly threaten human survival.
3. Solid waste is rampant, and the phenomenon of garbage siege is serious.
Human life and production produce a lot of solid waste. At present, China produces 660 million tons of industrial solid waste every year, including 30-40 million tons of hazardous waste, with a cumulative amount of more than 6.4 billion tons, occupying more than 500 million square meters of land. The annual output of domestic garbage is 1 ton, increasing at the rate of 7-8% every year. Due to the open-air accumulation of solid waste in China, two-thirds of the cities in China are surrounded by garbage. Stacking solid waste everywhere not only hinders the view, occupies land and spreads diseases, but also seriously pollutes the environment and intensifies the pollution of water bodies and atmospheric soil.
4. Noise disturbing people is very common.
At present, with the rapid development of industry, transportation, culture and entertainment in China's cities, the phenomenon of noise disturbing people is becoming more and more prominent. According to the monitoring of 44 state-controlled cities, more than two-thirds of urban residents in China live in an environment with excessive noise, and the equivalent sound level of regional environmental noise is distributed in 5 1.5-65.8 dB(A), among which the average equivalent sound level of Luoyang, Datong, Kaifeng, Haikou and Lanzhou is. The equivalent sound level of road traffic noise ranges from 68.0 to 76.3 dB (A).
Urban environmental protection planning and its main data
Based on the above-mentioned environmental crisis, people have gradually realized the relationship between urban planning and urban development in recent decades, and began to use scientific planning to guide urban construction. According to the general policy and strategy that China's environmental protection should adhere to the simultaneous planning, implementation and development of economic construction, urban and rural construction and environmental construction, and realize the coordination and unification of economic benefits, social benefits and environmental benefits, urban environmental protection planning should mainly carry out the following aspects:
1. Preliminary preparation for urban environmental protection planning
These preparations are the basis of urban environmental protection planning, including urban natural environment information, such as geographical location, ecological environment, meteorology, hydrology and so on. Social and economic conditions of the city, such as population and gross national product; Investigation and analysis of monitoring data of atmosphere, water body and noise, sources and accumulated amount of solid waste over the years, pollution control and other environmental conditions; Present situation analysis and functional zoning of urban ecological environment.
2. Comprehensive air pollution control planning is to divide the functions according to the present situation and development trend of urban air quality, and calculate the maximum allowable emissions and reductions of each functional area according to the proposed environmental objectives, so as to formulate pollution control planning. To control air pollution, we should determine the primary pollutants according to the energy structure and traffic conditions of the city, that is, pollutants with high concentration, wide range and great harm, so as to control them in a targeted manner and prescribe the right medicine. At present, air pollution in most cities in China is mainly caused by coal burning and automobile exhaust, and the primary pollutants are sulfur dioxide and total suspended particulate matter. Therefore, the long-term goal of the planning should be to improve the backward olefin coal mode, improve the combustion efficiency, try to use gas fuel, briquette, solar energy, geothermal energy and other pollution-free or less polluting energy sources, implement regional central heating, eliminate small chimneys of thousands of households, improve the road hardening rate, and establish a smoke-free control area by strengthening pollution control and improving pollution control technology. Adjust the industrial layout and make scientific and convenient use of atmospheric environmental capacity according to the law of atmospheric self-purification; Strengthen pollution source control and reduce pollutant discharge; Reduce automobile exhaust pollution through technical and administrative means; Improve the urban greening rate, select tree species with good pollution resistance, and vigorously develop plant purification.
3. Comprehensive water pollution control planning
Based on the investigation and analysis of the present situation of water pollution, the comprehensive water pollution control plan is to calculate the maximum allowable discharge and determine the best control scheme according to the environmental capacity of the receiving water body. At present, the degree of water pollution in seven major water systems in China is increasing and the scope is expanding. 1996 The polluted water of the Yangtze River, the Yellow River, the Huaihe River and the Songhua River 1996, the national industrial wastewater discharge was 50.29 billion tons, including 7.04 million tons of chemical oxygen demand, 2,457 tons of heavy metal1565,438 tons, cyanide and tens of thousands of tons of pollutants such as arsenic, phenol and oil. Domestic sewage accounts for about 24% of the total annual discharge, and the main pollutant is organic matter. According to the specific situation of water pollution in China, the comprehensive water pollution control plan should reform the backward production mode and adopt the technology of less waste and no waste to realize clean production, improve the sewage treatment effect and resource utilization rate, reduce sewage discharge, build effective sewage treatment facilities and strengthen the treatment of industrial wastewater and domestic sewage, so as to finally achieve the purpose of effectively protecting water resources.
4. Comprehensive improvement planning of urban solid waste
The comprehensive treatment planning of solid waste is to implement the comprehensive utilization rate of all kinds of solid waste, the treatment and disposal index system and formulate the final treatment countermeasures according to the environmental objectives. At present, many cities in China are surrounded by solid waste, so it is urgent to solve the problem of solid waste. The purpose of solid waste comprehensive treatment planning is based on the economic carrying potential of cities and urban solids.
At the Mayor Summit of National Environmental Protection Model Cities, Wang Jirong, deputy director of the State Environmental Protection Administration, said that cities are symbols of modern etiquette, reflecting the comprehensive strength of the country, the management potential of the government and the international competitiveness of the market. The urbanization of China is not only beneficial to its own development, but also affects the future trend of world cities. China has few per capita resources and its ecological environment is inherently fragile. China urgently needs to create the greatest economic and social benefits with the least resources and environmental costs, and embody "harmony between man and nature and equality between people" in the sustainable development of the city, which will also become the development trend of China.
Article 4:
I. Summary
The social practice of this winter vacation was carried out in Yuhuan, not far from Jinan University. I work as a waiter at Malan Ramen Restaurant in Yuhuan b 1 Building. During the one-month internship, I fully exercised my talents, gained a lot of knowledge and eliminated my inertia. In face-to-face communication with customers, my interpersonal potential has been improved. Personality quality and all aspects of potential have also been directly and effectively exercised and cultivated. This month's professional life has enriched my life experience, gained valuable knowledge and experience, deepened my understanding of society, and gained many insights and experiences in many fields.
Second, the text
When I stepped into the university hall, it was also when I spent nearly 20 spring and autumn, and I became a college student. I can't do nothing, and I don't have long or short social experiences like other peers in the past 20 years. I have never really earned my first bucket of gold independently, and I have never really experienced social life. I used to study at home or enroll in remedial classes in winter and summer vacations. At that time, learning was the whole of life. Now that we are in college, we have more time to arrange our life and study and plan our life reasonably. There is plenty of winter vacation time in the university, so the first winter vacation in the university can't be wasted and there is no gain. With the support and encouragement of my family and friends, I decided to have a really beneficial and fulfilling holiday.
Jinan University has always carried out the study and implementation of the spirit of the 18th CPC National Congress, guided young students to seriously study and understand the spirit of the 18th CPC National Congress, carried out employment practice activities, and conducted in-depth research activities to help college students establish the spirit of self-esteem, self-reliance and self-improvement and an optimistic attitude towards life, so that they can have a full and beneficial holiday. To this end, Jinan University launched the activity of "Dedicating Youth Footprints to the Party, Serving the Society and Promoting Development". As a student of Jinan University, I have tried to be self-reliant according to the call of the Party.
My job search process is not as difficult as others. I am very lucky. You can join the job smoothly without an interview. I successfully entered Malan Ramen Restaurant through the introduction of a senior sister, probably just a temporary worker, so the company doesn't have too many requirements. After completing a series of admission procedures including health certificate and work permit, I started my first professional process. The job of a waiter is basically not very difficult.
This is a job that has little to do with my major in chemistry and chemical engineering. Although I can't get a good professional exercise, for a freshman who has no work experience and is a fledgling, working nine hours a day, 60 yuan's salary is already very satisfying, which is a very good opportunity to make money and study and exercise, so I didn't give up and decided to go on. I wasn't busy at first, just because I was a novice. Unfamiliar with the working environment and materials, I was a little self-righteous from the beginning and made a mess. Fortunately, the supervisor of Malan front desk is an easy-going girl. She always teaches me patiently: take your time, it's not difficult. You are so clever that you can certainly learn.
Under her careful teaching, I grew up slowly, and soon everything was ready and entered the formal stage.
Although the work is not difficult, it needs to be serious. For example, Lamian Noodles in our store has many flavors, so we should fully consider the situation when introducing it to customers.
Some customers bring children, some customers don't want coriander, some customers don't eat green garlic and so on. Therefore, it is necessary to make it clear to customers which Lamian Noodles is spicy and which is clear soup, and whether to put coriander and green garlic, so that customers can choose according to their own preferences and conditions to achieve their satisfaction.
When I entered Malan Ramen Restaurant, I also learned about the origin of Malan and fell in love with a flower? Malanhua, a symbol of hard work and courage, has a deeper understanding of the production and processing of Lamian Noodles Lamian Noodles.
I also exercised myself in the process of direct communication with customers.
No matter what happens, I will always do what a waiter should do, be polite in conversation and try my best to meet the various needs of customers.
Because we all stand at work, I am not used to standing at ordinary times, so my feet are not used to standing for a long time, and gradually the soles of my feet begin to hurt, blister and peel off.
Although it is not a bone-breaking pain, I find it hard to bear. I have been looking forward to getting off work early and ending this ordeal early. But for my indomitable faith, I persisted. I beat myself, exercised my potential for hard work and cultivated my perseverance.
In Malan Ramen Restaurant, I also met some colleagues and learned that most of them are from other provinces, and most of them have junior high school education. I also asked them why they didn't continue their studies, some because they didn't get into high school, and some because their families couldn't afford it. They are about my age and came to work in this city at the age of sixteen. From their words, I felt their yearning for learning. This makes me feel that I should cherish this opportunity to gain more knowledge, but I also learned the truth of heaven and diligence from them. Although their academic qualifications are not high, it is really touching that they have to earn money by their own hands to support themselves and their families.
This is my first time to participate in social practice. I understand that college students' social practice is a good situation to guide our students out of school, into society, into contact with society, into society and into society. It is a good channel to train them to train talents, and an effective way to improve their thinking, cultivate their self-cultivation and establish the concept of serving the society. By participating in social practice activities, we can help our college students update their ideas, absorb new ideas and knowledge, and learn a lot from them. And social practice has deepened me and all walks of life.
Three. Concluding remarks
No matter what happens, only by personal experience can we have a real feeling and a deep understanding. "Nothing is difficult to a willing mind" is my true portrayal. In the future, I will take part in more social practice activities, experience a different life, constantly improve my social practice potential and become an all-round talent.
