Investigation report on environmental pollution in Zhuhai city

Are you aware that the environment around us is being seriously damaged day by day? Deforestation, water and air pollution, destruction of the ecological environment. Countless facts tell us that environmental protection is urgent. Protecting the environment is not only the responsibility of the state and government departments, but also the responsibility of our citizens.

These days, I investigated the degree of air pollution around me and the harm of air pollution to human health.

According to the environmental characteristics around Zhuhai and the problems found, I conducted an online survey.

According to the survey, the air around us is polluted. Pollution sources are mainly black smoke from factory chimneys and tail gas from motor vehicles. What pollutants do these pollution sources emit? What is the harm to people's health? I consulted relevant materials and learned a lot about air pollution.

The main pollutants in the atmosphere are carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides and particulate matter. If their content in the air exceeds a certain standard, it will endanger people's health. The air pollution index is less than 50, which means that the air is good, and the pollutant concentration is lower than the first-class standard limit in the Environmental Air Quality Standard, which is Grade I, which meets the air quality requirements of some areas that need special protection, such as nature reserves and scenic spots.

The air pollution index is more than 50 and less than 100, which means that the concentration of general pollutants in air quality is less than the second-class standard limit in the Ambient Air Quality Standard, which is good at the second level and meets the air quality requirements of urban residential areas, commercial traffic mixed areas, cultural areas, general industrial areas and rural areas.

Preventing air pollution and controlling pollution discharge are fundamental measures to improve air quality. The main ways are: reasonable industrial layout and good environmental planning; Change the energy structure, popularize clean fuels and adopt clean production processes to reduce pollutant emissions; Strengthen energy conservation, improve energy utilization rate and regional central heating; Strengthen environmental supervision and management and control of old pollution sources, and implement total control and discharge up to standard; Strictly control automobile exhaust emissions.

Zhuhai is our home, and we should build it better. But the air pollution problem is very serious. What shall we do? I suggest:

(1) Three-dimensional greening, expanding the green area, can be soilless culture. Plants can filter all kinds of toxic and harmful air pollutants and purify the air, especially forests, so afforestation is a more economical and effective measure to prevent and control air pollution.

(2) Solve the fuel problem, and try to use energy with no pollution or less pollution, such as solar energy.

(3) Organize publicity activities and consultation activities to enhance people's awareness of environmental protection.

(4) Organize students to pick up garbage in streets, markets and squares on weekends to keep the environment clean and tidy.

Today, we are masters of tomorrow's society. Protecting and improving the surrounding environment is the unshirkable responsibility and obligation of our generation. We should start from me, start from the small things around us, care about environmental protection, pay attention to saving resources, recycle waste products, participate in environmental protection activities, plant more trees and flowers, and be a veritable little guardian of environmental protection!

Students like lively teachers for the following reasons:

(2) When learning the text, the teacher speaks vividly, which makes students interested in this subject. Naturally, they listen carefully, think about problems, use their brains and actively raise their hands to speak.

(3) Since the teacher gives lively lectures, won't it attract students to learn and make them love and love learning?

(4) It is natural that students like teachers who speak well. Teachers can make our study happier, easier and more enjoyable.

(5) Students only like teachers' courses that can be taught, because other teachers are boring, so students will casually deal with teachers and be careless.

(6) Teachers who know how to lecture will leave a deep impression on students and will not forget the text just after class.

And people like teachers who are integrated with their classmates because:

(1) Students don't like that fierce teacher. They all want teachers to play, play, study and share with us.

(2) Students talk with their teachers, talking and laughing, which can narrow the distance between teachers and students, so that teachers and students will not be like strangers, and some students will be afraid when they see teachers.

(3) Such a teacher will respect the teacher in class, so he will not attend class like coping, but concentrate on listening and learning.

(4) Every student wants to show his best side to his favorite teacher, so students do everything meticulously and seriously in front of their favorite teacher. Such a teacher has such great charm that students can do everything well.

(5) Teachers who are integrated with students are bound to be loved by students, and students will listen to their words, listen to their education and have fun with them, which is very important for students' learning.

(6) Every student wants the teacher to know more about himself and get together more, so that students can learn and know how to be happy.

(7) If a student is in class and the teacher in the class is very strict, he will be afraid, but the teacher in the class is not, so he will boldly play, speak actively and show himself in class as usual.

China New Year Survey Report

China New Year Survey Report

China is a multi-ethnic country with a vast territory and a long history. All ethnic groups have their own traditional festivals, and the Spring Festival is one of the most solemn festivals of the Han nationality.

Time flies, a busy year, and this grand festival is coming. How will Changshan people spend this Spring Festival in 2005? In order to understand the arrangement of this year's Spring Festival, we conducted a survey of the society. It is understood that 85% of people in Changshan follow the procedure of "sweeping dust-buying new year's goods-posting Spring Festival couplets-celebrating New Year's Eve-collecting lucky money-greeting the New Year".

Sweeping dust: According to the survey, 80% of people start one week before the Spring Festival. In this process, people mainly clean furniture and electrical appliances. And some busy people will not start work until the company has a holiday, or ask relatives to help clean up. Some rich people ask nannies to clean up. So why do people sweep the dust on the eve of the Spring Festival? According to the survey, on the one hand, people hope to have a clean environment to welcome the New Year, on the other hand, this is a superstitious statement, and they hope to get rid of the bad luck of the previous year and welcome the New Year happily.

Shopping on New Year's Day: Some people start preparing a month before the Spring Festival in order to buy cheap and good goods. But more people will still be busy one week before the Spring Festival. After the first day or two of the Spring Festival, people will be busier. Kill chickens and ducks, even children can help adults carry water.

Post Spring Festival couplets: As far as we know, Spring Festival couplets are very common in modern society. They basically use black characters on a red background or gold characters on a red background to deepen joy and drive away evil. In general, the time to post Spring Festival couplets is New Year's Eve, but some families advance because they want to travel. American Tmall Pu WeChat reminds us to take precautions when traveling in foggy days.

Celebrate New Year's Eve: What people do on the eve of the Spring Festival is to welcome this exciting moment. What will people do at this time? As far as we know, 88% people think that those who watch the Spring Festival Gala are 60% elderly people, because the wonderful and interesting performances attract them. There are also 15% young people who think it is more appropriate to hold a party on the computer. So what will the other 2% people do? They are watching the beautiful fireworks in the sky.

Collect lucky money: in most families, children are the happiest in the New Year, bearing the infinite warmth of their families and the care of their loved ones, and growing up in happiness! In order to give children a new year's motivation, some families often give them some lucky money to congratulate them on growing up another year old. Children will also happily accept lucky money and say some words of thanks to their relatives, so in modern life, there are often some congratulations like "Congratulations on getting rich and bringing a red envelope". Doesn't this custom also show the long-standing traditional virtues of the Chinese nation?

New Year greetings: This is a kind of respect for elders and a way to congratulate them on the Spring Festival. According to the survey, 66% people in Changshan also have the custom of paying New Year greetings. Their main time is from the second day to the fifth day of the lunar calendar, mostly in rural areas. When visiting New Year, most people will bring some gifts to express their congratulations on the Spring Festival. As for the host, they will leave a meal for their guests and even be grateful. The customs during the Spring Festival not only enrich the life of the Han people, but also reflect the long history and traditional culture of the Han people. As children of 2 1 century, we should study hard, make progress every day and be ready to inherit the glorious tradition at any time.
