1. Research background

Recently, there has been another drought in the southwestern region of our country. Not to mention growing crops, it is difficult to guarantee the water for people to drink. I always find it unimaginable. Isn’t water the most abundant thing on the earth? Aren’t there so many big rivers, big rivers, big lakes, and seas? How can there be a shortage of water!

Later, I checked on the Internet about water resources. After reading the information, I realized that water is the source of all life on earth. The total amount of water on Earth is 18 trillion liters. This amount seems to be enough to meet the water needs of the global population, but the actual situation is not optimistic. 99% of the existing water reserves are seawater and polar ice that are not suitable for human use, and the remaining 1% are mostly in strata below 800 meters. The water in rivers and lakes that people rely on for survival only accounts for 0.01 of the total. Already 18 countries in the world have less than 1,000 cubic meters of renewable water resources per capita. According to a report by the World Resources Institute, 3.4 billion people in the world only receive an average of 50 liters of water per year, indicating that humans are facing a crisis of fresh water shortage.

Our hometown is located on the coast of the Yellow River. Although water resources are relatively abundant, most of the water is seawater, and seawater is salty and cannot be drank directly. Most of the fresh water we drink daily is distributed in In the cold north and south poles of the earth and in the high mountains covered with snow all year round, there is not much freshwater resources left, and they are unevenly distributed, with more in the east and less in the west, more in the south and less in the north, and there are many places that are short of water. Therefore, the water flowing to our hometown for living and production is even scarcer. With the rapid development of urbanization and industrialization in our hometown, the rivers and lakes on which we depend for survival are facing increasing threats of pollution. The water crisis has sounded the alarm to us!

2. Research purpose

(1) Let us understand the current situation of water pollution in our hometown and understand the importance of protecting water resources.

(2) Let students know the dangers of water pollution, so that students can care about and protect the water resources in their hometowns.

(3) Cultivate students to love their beautiful hometown, love society, love nature, and develop good habits of saving water since childhood.

(4) Improve students’ ability to penetrate into society, care about society, and integrate into society.

3. Research process

(1) Research time: April 20, XXXX

(2) Research location: Xiangkan River in XXXX Town , Zhongshan River Basin

(3) Research methods: Asking elders, field visits

(4) Research team members:

Team leader: Teacher Wang

Team leader: Yang Xueqi

Members: Group 3 students of Class 5 [5] of XXXX County Experimental Primary School

IV. Research results

Ten years ago :

Water color: colorless; water use: domestic water, agricultural water; river size: general size; floating objects on the water: aquatic plants and other aquatic plants.

Now:

Color of water: mostly black; uses of water: domestic water, agricultural water, industrial water; river size: many rivers narrow and the river bed rises; Floating objects on the water: white garbage, domestic garbage, etc.

5. Analysis of the main reasons

(1) Residents’ awareness of environmental protection is not strong. Many residents throw domestic garbage into the river at will.

(2) As farmers use more and more chemical fertilizers and pesticides during planting, the water quality is getting worse and worse.

(3) Wastewater from some factories is discharged directly into rivers without sewage treatment, causing water quality to deteriorate and aquatic plants to die.

VI. Suggestions

In view of the current situation that water resources in my hometown have been polluted, I put forward the following suggestions:

(1) Make full use of radio, television, The Internet and other communication media should strengthen the publicity of the significance of water resources protection and make environmental protection awareness deeply rooted in the hearts of the people.

(2) Encourage residents to save water, promote water-saving equipment, and minimize the use of chemicals in daily life.

(3) Encourage farmers to reduce the use of pesticides and chemical fertilizers as much as possible, and change planting varieties to a variety of drought-resistant plants.

(4) When sewage is discharged from factories, it must be treated and discharged up to standards.

(5) It is hoped that the government will strengthen environmental protection management, increase investment in environmental protection, formulate a series of laws and regulations to protect water resources, and impose strict restrictions and regulations on wastewater discharge and other aspects, so as to build a green city. Protect your home.

1. Question raised:

According to a survey of the current situation in our country There are more than 5 million blind people and nearly 10 million people suffer from low vision, especially among children and adolescents, the prevalence rate is extremely high. The latest data from the National Student Physical Health Survey show that the incidence of myopia among primary school students in my country is 22.78%, that of middle school students is 55.22%, and that of high school students is 70.34%. What is even more shocking is that a survey report stated that more than 300,000 people in China have been blinded by high myopia. Therefore, the prevention and treatment of myopia in children and adolescents has attracted more and more attention from students, parents and society. How many myopic students are there in our class? Why are those myopic students myopic? How to prevent myopia? Is it just caused by bad eye habits? In order to understand the myopia situation of primary school students and the related factors that cause myopia, our team investigated and analyzed the myopia situation in this class.

2. Investigation method:

1. Observe and record yourself.

2. Investigate, visit.

3． Excerpts from books and newspapers.

4． Use web searches.

3. Investigation and data compilation:

1. Currently, 2 people in our class are myopic, accounting for about 4.2% of the whole class. The fundamental reason is that we don’t pay attention to protecting our eyes. , no attention was paid to the prevention of myopia.

2. There are many causes of myopia, the main factors are: genetic factors, environmental factors, individual factors, nutritional factors and sleep factors. The main causes of myopia in primary school students are not paying attention to eye protection, incorrect reading and writing postures, inappropriate lighting, lack of sleep, excessive watching TV, playing computer games, and consuming a lot of protein.

3. Myopia is also called shortsightedness, because this eye can only see near but not far. When this kind of eye is at rest, the parallel light coming from infinite distance, after being refracted by the eye's refractive system, is focused on the retina and forms an unclear image on the retina. The distance vision was significantly reduced, but the near vision was still normal.

IV. Conclusion:

(1) The main causes of myopia:

1. Watching TV and computers too close and for too long;

"Eight major cuisines", Western food is divided into French, British, Italian, Russian, American, Mediterranean and other different styles of cuisine.

IV. Conclusion

1. The main characteristics of Western food are outstanding main ingredients, beautiful appearance, delicious taste, rich nutrition, and convenient supply.

Chinese food has a wide range of ingredients, including flying, diving, animals and plants. The raw materials can be processed into fine shreds, cubes, slices, minced and other cuts. In terms of taste, most Chinese dishes have an obvious salty taste. , and full of variety, color, fragrance and flavor.

2. There are different etiquettes when eating Chinese and Western food:

Middle: Seating: This "hero's seating arrangement" is the most important item in the entire Chinese dining etiquette. From ancient times to the present, due to the evolution of tables, the arrangement of seats has also changed accordingly. Generally speaking, the seating arrangement is "to the left and to the east" and "to the front of the door is to respect". At a family banquet, the chief seat is the elder of the seniority, and the last seat is the lowest seat. At a family banquet, the chief seat is the guest with the most respectable status, and the host of the guest occupies the last seat. No one can take a seat until the chief is seated, and no one can take a seat until the chief makes a move. During the wine tour, everyone starts from the chief and drinks in order.

West: The higher-end hotels require reservations in advance. When making a reservation, not only specify the number of people and time, but also indicate whether you want a smoking area or a seat with a good view. If it's a birthday or other special occasion, you can tell us the purpose and budget of the party. It is basic courtesy to arrive within the scheduled time.

No matter how expensive your casual clothes are, you cannot wear them casually to a restaurant. Dressing appropriately when eating is common sense among Europeans and Americans. When going to high-end restaurants, men should wear neat tops and leather shoes; women should wear suits and heeled shoes. If formal attire is specified, men must wear a tie.

Sit from the left side of the chair. The most appropriate way to sit is from the left side. When the chair is pulled away, stand up straight at a distance that is almost touching the table. The leader will push the chair in, and you can sit down when your legs touch the chair behind you.

The formal order of serving the full meal is: ① vegetables and soup ② cod liver oil ③ fruit ④ meat ⑤ cheese ⑥ dessert and coffee ⑦ fruit, as well as pre-dinner wine and table wine. There is no need to order everything. It would be rude to order too much and not be able to finish it. No decent restaurant welcomes people who only order appetizers. Appetizer, main course (choose one of fish or meat) and dessert are the most appropriate combinations. When ordering, you don't start with the appetizers. Instead, you choose the main dish you want to eat the most, and then pair it with the soup that suits the main dish.

3. Chinese and Western foods also have different nutritional components. The popular diet in developed countries in the West currently uses meat as the main source of energy. It is characterized by being too energy-dense and rich in fats and oils. Sugar and lack of complex carbohydrates. The traditional diet of Chinese residents is based on cereals as the main source of energy. The calories it provides account for about 75% of the total dietary calories, the protein it provides accounts for about 66% of the total protein, and the calories provided by animal foods account for about 8%. Protein provided is approximately 11.
