Research report composition 1 1. Students, do you know? China's Chinese characters are very interesting. It is a unique culture in China, but I also have many questions: How did Chinese characters change? Who invented Chinese characters?
Second, research methods.
1, looking for information online
2. Ask teachers and parents.
3. Other methods
Third, data collation.
1, Oracle Bone Inscriptions is the earliest Chinese character. At that time, it was all pictographs. Later, with the change of dynasties, Chinese characters are constantly changing, and Chinese characters have evolved through many dynasties to form our current Chinese characters.
2. Specifically, Chinese characters evolved from Oracle Bone Inscriptions, inscriptions on bronze, big seal script, small seal script, official script, cursive script, regular script and running script, which can be simply summarized into five stages: sound, shape, image, number and reason.
The ancients invented Chinese characters because people needed better communication. Simple knotting notes and drawing notes can no longer meet people's needs. Because people thought it was troublesome, ancient people invented Chinese characters. Later, Chinese characters evolved in the long river of history, forming our present Chinese characters.
Fourth, research results.
I think China's ancestors were so clever that Chinese characters deserve the pride of every Chinese son and daughter. After continuous evolution, Chinese characters are now very concise and beautiful, and they are worthy of being a national treasure. We are now living in such a good sunshine and learning environment. We should study hard to add luster to our country and develop Chinese characters in China.
Research Report Composition 2 I went to Nanchang Botanical Garden last summer vacation, but I couldn't forget pistachio, bodhi tree and elephant foot tree, but I like pistachio best.
Pistachio nuts are oval red fruits. It is only 2 cm long, and there is nothing mysterious on the surface. The narrator's aunt said, "The secret of pistachio lies in its ability to change people's tastes. When people eat sour, bitter, spicy and other flavors of food, it will immediately become sweet and last for 30-50 minutes. " That day, I came home and thought: Why do pistachios taste in my mouth and everything becomes sweet?
Later, I asked my parents, and they said, "There may be something stale in it, but I'm not sure about it." So I went to the internet to check the information, only to know that it contains an odor white enzyme (also known as mysterious fruit element). Although it can't really change the taste of food, it can change people's taste and make all food feel sweet. Therefore, after people eat this mysterious fruit, they think that eating any food is sweet.
It seems that the role of pistachios is really great! If you want to eat some pistachios before taking medicine next time, you won't feel bitter! Plants are our friends, please don't hurt them!

2. Other methods.
Third, data collation.
Origin of Chinese Characters: It is said that Cang Xie made a mistake in the historical facts provided to the Yellow Emperor from the historical records recorded in the structure, which led to the defeat of the Yellow Emperor in the border negotiations with Emperor Yan. Later, it was a good way for Cang Xie to resign, travel around the world, visit and record historical events. Three years later, he returned to his hometown, Baishui Wu Yang Village, and lived alone in a deep ditch. He collected various materials and created various symbols representing everything in the world. He gave these symbols a name, Chinese characters.
Evolution of Chinese characters: Oracle Bone Inscriptions, inscriptions on bronze, seal script, official script, regular script, cursive script and running script.
Chinese homonym: nephew playing lanterns-the old rule (uncle)
Confucius was moved-all lost (book)
Military strategist-useless place (Wu)

Research Report Composition 4 I. Question Raising
Elders often compare their past lives with the present situation and tell us to study hard and cherish them, so I want to know what the past lives of grandparents and parents were like, so I made a research and investigation on the changes of our family life.
Second, the survey method
1, ask mom and dad
2. Look at the photos left by my parents before.
Three. Investigation and data collation
1, mom and dad used to have only one bike; There is a car now.
2. Mom and Dad used to live in their hometown and only had a three-story building built by themselves; Now I have a comfortable house.
When mom and dad used to live in their hometown, there was no gas. When cooking, they have to cook with their own firewood. Now with gas, it can save a lot of time and effort, and it is more convenient.
Mom and dad only ate chicken, duck and fish when they were children. Now our family can eat big fish and meat every day.
My father was a boarder when he was a child, and he didn't even have twenty cents to buy soy sauce. He occasionally eats pickles, radishes and steamed taro soup.
6. In the past, there was only one 12 inch TV in a village, and all the men, women and children in the village gathered there to watch it.
Four. conclusion
Living conditions used to be very poor, but now they are much better than before. In the past, cooking was made of wood, but now all it takes is gas. There are computers that can serve us now. Times are changing so fast!

History of Chinese Characters: Oracle Bone Inscriptions is the earliest Chinese character, which was discovered by the late Qing Dynasty King. He has malaria. A famous old Chinese doctor gave him a medicine called "keel", and Wang found some symbols engraved on this "keel". He likes ancient Chinese characters, and has been collecting this thing, scrutinizing and piecing it together, and found that it was discovered by Oracle Bone Inscriptions and Oracle Bone Inscriptions in the Shang Dynasty. Later, he discovered the bronze inscriptions in the Western Zhou Dynasty, also known as Zhong Dingwen, and the seal script in the late Western Zhou Dynasty. Xiao Zhuan is a unified font issued when Qin implemented official script. Lishu originated in the Qin Dynasty and prevailed in the Han Dynasty. Regular script came into being at the end of Han Dynasty, also known as real script and official script. It prevailed in Wei, Jin, Southern and Northern Dynasties and matured in the Tang Dynasty. Regular script, cursive script and running script have been used to this day.
Famous calligraphers: Famous calligraphers include Yan Zhenqing, Wang Xizhi and Liu Gongquan.
The words of famous calligraphers: Yan Zhenqing's regular script tablet and Wang Xizhi's masterpiece Preface to Lanting.
Four. Research conclusion
1. There are Oracle Bone Inscriptions, Jinwen, Dazhuan, Xiaozhuan, Lishu and regular script.
2. There are calligraphers Yan Zhenqing, Wang Xizhi and Liu Gongquan.
3. Yan Zhenqing wrote "Qin Bei" and Wang Xizhi wrote "Preface to Lanting".
Because the Internet is more popular now, most of our students have computers at home. And computers also have two sides, good and bad. On the positive side, I have increased my knowledge and broadened my horizons. The bad side is: indulging in games leads to a decline in academic performance. To this end, I made a survey report about students surfing the Internet.
In grade five, 44% of boys surf the Internet in Internet cafes, 35% in school computer rooms and 2 1% in other places. Among them, 40% are playing games, 50% are chatting, 2.7% are looking up information and 4.3% are doing other things. 1.2% of girls surf the Internet in Internet cafes, 50.8% surf the Internet in school computer rooms and 48% surf the Internet at home. Among them, 2 1% is playing games, 15% is chatting, 5% is looking up information, and 1 1% is doing other things.
Through the above figures, it shows that surfing the Internet does more harm than good to primary school students. I don't think I should spend more than 30 minutes online every day. I just look for some helpful materials or read excellent articles to improve my writing level, enrich my spare time and make progress in my study every day.
Nowadays, people's lives are getting better and better, and most families have bought cars. Due to the popularity of cars in the street, many people can't walk now.
In this regard, I specially conducted a detailed investigation during the rush hour and made a survey report form. Time: 5: 00-6: 00 p.m. on March 5th, 20xx 1 5 Location: at the cross traffic lights next to xx Electrical Appliance City, Shuguang West Road. Situation:1. Table of people who can walk the zebra crossing: students, middle-aged and elderly people: * * 30 students: 17 people, middle-aged people: 5 people, elderly people: 8 people Percentage: students: 56% middle-aged people: 16% elderly people: 28% Second, table of people who don't walk the zebra crossing: students, middle-aged and elderly people. 5% From the above table, we know that most people who don't take the zebra crossing are middle-aged.
Maybe they think they are young and strong, running fast, and don't have to walk the zebra crossing. However, they don't know that many tragedies happen under the protection of this concept. Here, I propose to all my uncles and aunts that walking the zebra crossing is equivalent to giving yourself a guarantee of life. Let the traffic tragedy stay away from us, let's bid farewell to the traffic tragedy!
Research Report Writing 8 I. Question:
Our Chinese nation is a famous cultural nation, and idioms are one of the crystallization of cultural nations. The teacher said that every idiom has a celebrity story. Therefore, I studied the celebrity stories in idioms.
Second, the survey method:
1. Read books about celebrity stories in idioms and learn about celebrity stories in idioms.
2. Browse the Internet and collect celebrity stories in idioms through online channels.
3. Read the newspaper and learn about celebrity stories in idioms.
Three. Investigation and data collation:
The main contents of idioms and celebrities in information channels
Wang Xizhi's calligraphy in Jin Dynasty is very imposing. According to legend, he wrote on the board, and the engraver found that the ink had penetrated into the board for three points.
The history of the Song Dynasty visited the famous scholar Cheng Yi on a snowy day. Cheng Yi sat in the snow, and Shi Yang didn't dare to disturb him. He's waiting by. When Cheng Yi woke up, the snow behind the door was more than a foot deep.
At the end of the Eastern Han Dynasty, Zhou Yu was jealous of Zhuge Liang's talent and asked Zhuge Liang to build 100,000 arrows in ten days to frame him. Zhuge Liang fought Zhou Yu, borrowed an arrow from Cao Cao and finally defeated Zhou Yu.
Four. Conclusion:
There are indeed stories of famous people in idioms, which evolved from them. These idioms are of great help to us and will be used in our study and life. There are many qualities and advantages of celebrities in celebrity stories in idioms that are worth learning.
After the mid-term exam, I was surprised that more people were nearsighted. Why is there more "myopia"? Therefore, I investigated the causes of their myopia.
The survey method asks doctors to browse the Internet, and myopia people to consult relevant books and information channels. Ask a nearsighted person about his myopia degree of 300~350 degrees, ask a nearsighted person about his myopia degree of 50~ 150 degrees, ask a nearsighted person about his myopia degree of 100~ 150 degrees, and ask a nearsighted person about his myopia degree of 200~250 degrees. Ask the doctor what causes myopia and bad habits. What causes myopia and bad habits of surfing the Internet? Learn about books and the causes of myopia. Conclusion There are more and more nearsighted people in our class, and those who are already nearsighted are getting closer and closer. Some of these "shortsightedness" are caused by high concentration when doing things. Others are caused by reading something wrong.
Research report composition 10 I have a small snail, which was originally bought for science class, and now I have a strong interest in it. Through a period of observation and access to information, I have learned a lot about snails.
My little snail is right-handed and has six circles. It has two pairs of antennae on its head. One pair of tentacles is very long, about 1 cm long, and the other pair is very short, less than 9 mm long. Its eyes are on the long tentacles. If you look closely, you can see the eyes of a small snail!
The snail's mouth is round, and no one can see its teeth. In fact, it hides on the surface of the tongue in the mouth under the tip of its tongue. According to the data, the total number of teeth of snails can reach more than 10 thousand, and snails use them to scrape off leaves or grass for food. When teeth become dull after long-term use, new teeth will grow immediately.
If you touch an eye with your hand on the antenna of a snail, the antenna you touch will retract immediately and then slowly extend out, which is quite interesting. The small antenna under the snail's long antenna has the function of smell.
Snails like to live in dark, humid, loose and humus-rich environments. They stay up all day and go out at night, most afraid of direct sunlight.
Snails like to eat vegetables, such as green vegetables and cabbage. Put the dish aside, and it will slowly crawl over to eat. But don't forget that snails also need to drink water. If the snail doesn't move or looks dead, it must be short of water. As long as some water is poured on its back shell, body and leaves, the snail will return to its original state.
Research report composition 1 1 My hometown is Huozhou, Shanxi, and the Fenhe River flows through my hometown. According to my mother, Fenhe River is clear, sweet and crystal clear. The fish are playing happily. The tadpole is looking for its mother. Some people are washing clothes, some people are swimming in the water, and some children are playing with water. How beautiful Fenhe used to be, it brought happiness to people and animals!
But now, this clear river can no longer be seen, because it was taken away by terrible pollution sources. After my investigation, there are many reasons for the pollution of Fenhe River. Among them, the most important pollution source is the wastewater discharged from factories. Because people have built coal washing plants, power plants, chemical plants and cement plants in order to live a better life ... The workers here discharge useless sewage from the factories into the Fenhe River, and the small animals living in the Fenhe River are crying for help: small fish and shrimp can no longer play, tadpoles can no longer find their mothers ... Some people in their hometown are unsanitary and dump garbage into the Fenhe River. In this way, Fenhe became dirty and smelly. Writing here, my heart is heavy. I want to say, "It is really wrong for people to destroy the environment for their own benefit!"
Now, the government of my hometown has implemented the "blue sky and clear water" environmental protection project. I really hope to see the clear river as soon as possible!
Research Report Composition 12 Taking the opportunity of visiting New jiangwan city, I caught some tadpoles in an unknown ditch and took them home in mineral water bottles. As soon as I entered the room,
I excitedly and carefully put them into the basin. Observe them carefully, they gather and disperse. Almost oval chubby body, oily pure black, thin and long tail, flexible swimming style makes
I'm fascinated. This is simply a set of life notes! When a tadpole swims, it moves forward, backward or turns around. Its tail is like a paddle-like a rudder. It can not only generate electricity, but also master the direction. It's amazing! Small tadpole
It is less than 2cm long and weighs less than1/4g. It's lovely to play in the water. Seeing that they sometimes get together and don't move, I deliberately tap the edge of the basin with my fingers. When I saw them shaking their small tails rapidly and fleeing in panic, I couldn't help secretly rejoicing.
A few days later, I was surprised to find that they grew up a little. I also found that they have two hind legs, separated by tails. I said to them excitedly, "Wow! You are going to become frogs. " Soon, they grew two front legs and heads. I shouted, "Look! Tadpoles are going to take off their tails and become frogs! "
I want them to return to nature. But I really can't bear to part with them, and they seem to be reluctant to part with me. However, the little frogs decided to leave me, as if to say to me, "I'm really sorry, my friend!" " We have our own mission, to help heaven and eliminate pests-mosquitoes. "
The research report composition 13 saw the green aloe standing on the windowsill, and the sun shone through the window. Under the sunshine, he looks more like a brave soldier, with a sharp head looking up curiously, like a sharp peak tower.
I looked at the aloe tree curiously, and a strange question popped up in my mind: What's the use of this cactus? I was puzzled and thought: this cactus seems really useless! I have to run out to play. Suddenly, there was a big stone on the grass. I tried desperately to stop, but something unfortunate happened. My foot hit the stone at once, but the stone did not move, as if to say: what a suck! You asked for it! Ha ha! I was about to get up when I suddenly felt my feet hurt like needles.
I looked up, ah! I was shocked to see that there was still some blood on my leg. I wiped it with paper. Although the bleeding stopped, I still left a red scar. Mom quickly cut a small piece of aloe with a knife and put it on my leg. My leg will be fine soon. I asked my mother inexplicably: Mom, why can aloe cure diseases? Because aloe can cure any injury, and it can be beautiful after eating. Mom wiped it for me seriously. I quickly picked up my mobile phone and quickly searched for the use of aloe. Oh, it turns out that aloe has so many uses and can be eaten, but eating too much will cause diarrhea.
After this study, I feel that the mystery of life is really everywhere. Small aloe vera has such a great use, you should learn to explore it.
Research report composition 14 social progress makes people's lives better and better. Life is getting better and better, but people have less and less time to exercise. Therefore, I decided to study the importance of exercise to health.
After investigation, lack of exercise leads to a rapid increase in the proportion of obese people and a decline in people's health. Lack of exercise has become one of the main causes of human death and disability. 2 million people die every year in the world, partly because of lack of exercise. Because people's physical activity has been greatly reduced, 60% of people today will die from diseases rare decades ago, such as heart disease, stroke, diabetes and cancer. These are the consequences of lack of exercise, which shows that moderate exercise is very important to people's health.
Many people think that exercise is too bitter, too tired and tasteless; Busy work, more work and entertainment, no time for exercise. Some people sometimes go to play mahjong at night and have no time and energy to exercise; I sit after work. I have no sense of exercise, and I don't want to exercise, because I don't exercise for a long time, and I am very tired when I exercise.
In fact, proper exercise can improve heart and lung function, enhance muscle and bone function, improve blood pressure, enhance immunity, make our bodies healthier, strengthen our brains, eliminate fatigue and promote mental health.
For primary school students, more walking in the morning and evening, less exercise in class, playing ball games, skipping rope and other sports can all exercise our bodies. Everyone can have time to do moderate exercise, as long as you are willing to exercise, as long as you insist, it is not difficult to be healthy.
Research Report Composition 15 Today, my friends and I saw some reports on water resources in China on the computer:
China is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6/ 100 of the global water resources, ranking fourth in the world, second only to Brazil, Russia and Canada, but the average per capita is only 2,200 cubic meters, only 1/4 of the world level and 1/5 of the United States, ranking first in the world 1 2,200. After deducting the hard-to-use floods and groundwater resources scattered in remote areas, the available fresh water resources in China are even less, only about 1 1000 billion cubic meters, and the per capita available water resources are about 900 cubic meters.
After reading it, we were deeply influenced and decided to organize a "water rescue team". We are divided into grades and jobs, and we are going to go to the streets to interview and investigate. There are three of us, Wang Jian and I, interviewing negatives and Liu Zhu recording negatives. Wang Jian and I brought some interview tools and interviewed some city names at the end of the road. Most people say, "It's all the people who throw rubbish into the river, otherwise it wouldn't be like this!" " We think this makes sense. To sum up, our "water rescue team" believes that water resources should be rationally utilized: useless wastewater can be used to water flowers and plants; Taomi water can be used to flush the toilet ... We also advise people to save water. We can't throw garbage, waste water and other sundries into the river.
