New investigation report 1
Found the problem:
Planting some flowers and plants in the garden can not only beautify our home, but also purify the air around us and make the air we breathe fresher. So some people say that a garden with a certain scale is like a natural "oxygen bar", which can provide the fresh air we need without stopping working. But in recent days, I found that my natural "oxygen bar" went on strike. I can't breathe fresh air when I go to the yard every morning. What's going on here? What makes my natural "oxygen bar" ineffective? I'm determined to find the murderer!
Findings:
In response to the above events, I consulted a lot of information and made a comprehensive observation of flowers, plants and leaves for several days. What I found most suspicious was the frequent traffic in recent days, which caused serious air pollution. In addition, due to the recent weak wind, the oil fume emitted by some nearby food stores can not be effectively dispersed, and it is excessively absorbed by flowers and leaves, resulting in the pores on the surface of leaves being blocked by dust particles and unable to "work". I consulted the relevant teacher, and the teacher thought it was very possible, so let me go home and have a try. So I went back to collect some samples of flowers and plants, planted them indoors, basked in the sun regularly, and watered them encrypted. A few days later, compared with others, I found that the flowers and plants I carefully cared for grew much better than those outside. According to my experimental results, I encrypted the watering times to three times a day. After more than a week of painstaking efforts, the "natural oxygen bar" finally resumed normal work and provided us with fresh air every day.
Research conclusions:
To sum up, I come to the conclusion that the "natural oxygen bar" stopped working because of the increasingly serious air pollution around it, which made flowers and plants absorb excessive carbon monoxide, hydrocarbons, nitrogen oxides and suspended particles in the air, blocked the stomata used for photosynthesis in flowers and plants and leaves, and stopped working because of overload operation. I finally found the murderer.
Thinking after research:
Through this investigation, I am very happy to find out the "real murderer". At the same time, I can't help worrying about the future of mankind: my garden is already like this, and what challenges will the 600 million hectares of virgin forests around the world face! They have no one to water them, and they have to endure the pain caused by human beings. When people are enjoying the fruits of nature, have they ever thought about nature-the mother of human beings is suffering from infinite pain? As we all know, there are three important factors in the environment of human life: atmosphere, land and sea. But who would want to know that these three environmental factors on which human beings depend are being destroyed bit by bit by some unscrupulous businessmen! I don't want these "natural oxygen bars" and "thermostats" to be destroyed. By then, I won't be the only one out to investigate. Let's act together to stop these murders!
New survey report 2
First, the investigation background:
More and more students choose to travel on holidays, and it is also a common topic for college students to travel home in winter and summer vacations. Therefore, we want to further understand the tourism situation of college students in our school by investigating what kind of tourism methods college students choose.
Two. Investigation preparation process:
First, I looked up some information about questionnaires and reports on the Internet, designed a questionnaire by collecting all kinds of information and reference examples, and finally made a questionnaire by repeatedly consulting and referring to other people's opinions. Next, find the survey object, finally determine the survey population and feasible implementation plan according to the actual situation, and formulate specific investigation implementation plan. Since then, the preparations for the investigation have been basically completed.

5. Prediction of survey results: The topic of this survey is close to life. Due to some factors, the scope of the survey is too small, the number of people who can investigate is very limited, and the survey methods are not accurate and comprehensive enough, so the results are inevitably not accurate enough. Moreover, in different regions, due to the level of economic development and other reasons, local college students' choice of transportation will be different. Therefore, the survey results may be one-sided, but the survey can represent the students' choice of travel modes in Chongqing Energy Vocational College, which still has certain significance.

2) Analysis of survey results:
1. Choice of travel mode: 77% of the students are keen on going home by bus, and 14% people think that bus is the most convenient and quick choice.
2. Should we go out on holiday? Most of the energy students surveyed (82%) think that considering the reasons of time and cost, we should choose a closer place for entertainment on holidays. Ask specific students and learn that people generally choose the scenic spots in the main city of Chongqing for short-distance travel, which is the result of a variety of time-consuming factors.
3. The factors of travel mode choice:
Student Party, with the increasing demand for travel today, the choice of travel mode is mainly influenced by the following aspects:
① Travel expenses. Because college students have no source of income, the price factor is still the most important factor in travel. After all, taking a taxi is expensive, especially in Chongqing, and economic factors limit students' personal choices; In addition, some students are not very keen on the price increase of high-speed rail; On the contrary, everyone thinks that the most economical and applicable is the train. In addition, the inquiry method comprehensively knows that people who travel in the province are generally keen on car travel, that is, big customers.
② Travel time. Generally speaking, in order to avoid the rush hour, some students choose to travel early.
③ Travel distance. Some students will choose high-speed rail and other portable travel tools for long-distance travel. When the distance is relatively short, they will choose trains or cars, and then consider them according to the cost.
④ Number of trips. The number of peers is also a major factor in considering what kind of transportation to take when going out. When the number of peers is large, the survey found that people tend to take the train, which is cheap and can be entertained even for a long time; When the number of peers is small, the choice of outbound means of transportation will be wider and more mobile.
⑤ Travel location. The results of the questionnaire survey show that the destination also has a certain influence on the choice of transportation. Therefore, we can analyze that external economic factors also play a great role in our choice of transportation.
6. Travel object. The survey found that most people prefer to travel with roommates or boyfriends and girlfriends, and few people travel alone.
4. Waiting time: With the increasing traffic pressure, many people are unwilling to wait for more than 20 minutes. If they wait too long, they will change their travel plans and reduce their travel frequency.
Verb (abbreviation of verb) survey summary
As predicted by the survey, the topic of this survey is close to life. Due to some factors, the scope of the survey is too small, the number of people who can investigate is very limited, and the survey methods are not accurate and comprehensive enough, so the results are inevitably not accurate enough. Moreover, in different regions, due to the level of economic development and other reasons, local college students' choice of transportation will be different. Therefore, the survey results may be one-sided, but the survey can represent the students' choice of travel modes in Chongqing Energy Vocational College, which still has certain significance.
On the general issue of college students' travel, through investigation, our views are: college students should be fully thrifty, go out properly and choose cheap and suitable means of transportation; At the same time, we can firmly say that it will be more and more common for college students to go out in the future.

? Investigation process
Time: xx year 65438+1October 3 1 day 14: 30.
Venue: Beishanpo Railway Crossing
Object: traffic police
Q: What problems about pedestrian traffic are often found in the course of duty, and how do you deal with them?
A: It is common for pedestrians to violate traffic rules. Usually, there are no serious casualties, but there are serious security risks. At no time can we rule out the possibility of no casualties. For example, when you students cross this railway crossing, many of them cross the fence and cross the track, and few people can wait. The reason for this bad phenomenon is that casualties are accidental, and everyone's luck is more than safety awareness. In other words, as long as everyone has this bad luck and does not strengthen safety awareness, there is a great possibility of traffic accidents and the severity of accidents is great. Violation of traffic rules, the law can not completely bind pedestrians, pedestrians can not be fined as soon as they cross the track. We law enforcers can only play the role of reminding and supervising.
Summary:
The guarantee of safe travel is a kind of consciousness of our pedestrians, and traffic law enforcers and traffic rules can only help us strengthen this consciousness. The most important thing is that we pedestrians have a firm sense of safety and seriously abide by traffic rules.
Time: xx year 65438+1October 3 1 day 15: 15.
Venue: intersection of Shengli 3 rd Road
Object: traffic coordinator
Q: What should pedestrians pay attention to when crossing the road?
A: In the past, people always looked to the right at intersections without traffic lights, ignoring the vehicles coming from the left, so traffic accidents happened. First of all, everyone should cross the zebra crossing and pay attention to the traffic lights. This is the most basic and effective traffic safety guarantee. But many pedestrians ignore this point. Perhaps the quality of China people has not reached this level. Summary:
From the words of the traffic coordinator, it is not difficult to feel that he is angry that the traffic accident happened because pedestrians can't consciously obey the traffic rules, and he feels helpless about the behavior of some pedestrians. Obeying traffic rules can really reflect people's quality and ideological realm. We always believe that everyone has good qualities, but our consciousness needs to be strengthened. Start with the most basic traffic rules, strengthen safety awareness, improve their own quality and improve their own shortcomings.
Time: xx year 65438+1October 3 1 day 15: 45.
Venue: at the entrance of Chinese medicine hospital
Target: taxi driver (parked on the side of the road. )
Q: As a driver, what advice do you have for us pedestrians or do you think pedestrians should not cause you any trouble while driving?
A: ..... (Maybe this driver thinks that he only needs to pay attention to himself when driving, and there is no need to make any demands on us students. )
Summary:
Drivers and pedestrians crossing the road should pay attention to their own behavior, and it is necessary for everyone to establish a sense of safety. Both pedestrians and drivers should keep safety in mind and always obey the traffic rules.
Time: xx year 65438+1October 3 1 day 16: 15.
Venue: T-junction, Heping Square, Jiang Yan Road.
Object: Pedestrian (a middle-aged mother, with her daughter waiting for the red light. )
Q: Do you often remind your daughter of traffic safety? How did you tell her?
A: Actually, nothing. When I take her out or let her go out alone, I always remind her to say "cross the road when the green light is on", "cross the railway after the train" and "be sure to take the sidewalk". Probably said a lot, my daughter can pay attention to this. I was relieved that she crossed the road and railway at school alone.
Summary:
From the mother's answer, we can know that the establishment of safety awareness begins with the dribs and drabs of life. This little reminder made the girl notice the small details of safety, and unconsciously the little girl pulled away from the danger. It turns out that it is so simple to protect yourself and travel safely.
Time: xx year 65438+1October 3 1 day 16: 35.
Venue: T-junction, Heping Square, Jiang Yan Road.
Object: pedestrians (a young man running a red light)
Q: Hello, we are doing a social survey. Can you talk about the violation of traffic laws?
A: ... (The pedestrian refused our visit and left quickly with his head down and his face red. )
Summary: It seems that the pedestrian realized his mistake. Running a red light not only poses a threat to his life, but also brings trouble to the driver. If the driver can't accurately judge the direction of pedestrians, it will have serious consequences. Even if the judgment is correct, he will suddenly turn to other vehicles because he wants to avoid pedestrians, and the consequences are unimaginable. It is unwise to run a red light, climb a guardrail and cross the road, which violates traffic rules and is irresponsible for yourself and others' lives.
? Summary reflection
In this short and beautiful winter vacation, under the guidance of the school teacher, through the investigation of traffic safety in Yichang, our party has benefited a lot. We made clear the purpose of the investigation, worked out the investigation plan together, and determined the investigation method and object. We take No.7 Middle School as the starting point, and the north hillside railway crossing, turntable, Shengli Road intersection and Peace Park as the observation and investigation visit points. Based on what kind of traffic safety awareness pedestrians should establish and how to abide by traffic rules, we ask questions, interview street pedestrians, drivers, traffic police and coordinators, and observe the existing phenomena such as crossing tracks and running red lights at railway crossings. And make a further analysis of the results of the investigation and visit, and at the same time reflect on yourself more. Through this survey, we realize that consciously obeying traffic rules will make our life more orderly, and we can't ignore safety awareness because of luck. For example, when we go to school, we pass the railway crossing on the north hillside. Once the train alarm sounds and the guardrail is lowered, we should never risk crossing the guardrail and crossing the track. Can only calmly wait for the train aisle. Maybe this will delay our school time for a few minutes, but we will never struggle for these few minutes for a lifetime or even a lifetime. Be sure to be responsible for your own life and obey the traffic rules seriously: pay attention to the instructions of traffic lights when crossing the road at the crossroads; Pay attention to the left and right vehicles when crossing the crosswalk; Crossing the crosswalk by bike should be carried out by getting off; Don't stop at intersections and non-sidewalks; Don't grab the road, don't run the red light.
Obeying traffic rules is a manifestation of high quality and self-cultivation, and you should learn to travel in a civilized way. In addition to paying attention to the rules of safe travel, we should also remind our relatives and friends to obey the traffic rules and not to take unwise risks in order to race against time.
During the investigation and visit, we also noticed that traffic facilities should be more humanized. Our team recorded the time of the traffic lights at the intersection of Shengli No.3 Road and found that the time of the red light was several times that of the green light. The green light time of Shengli No.3 Road is very short, only ten seconds. From the green light, pedestrians haven't completely finished the zebra crossing, and then the red light flashes, so many pedestrians grab the road and grab the light. Of course, the problem of these facilities can never be a reason for us to make mistakes. Each of us with a sense of responsibility should take it as our duty to obey the traffic rules.
From this survey, we deeply realize that we must cherish our own lives, be responsible for our own lives, think about the safety and happiness of ourselves and others, and establish a good sense of security. "Caring for life and traveling safely" means asking us to take the initiative to cherish and protect life.
New survey report 4
I. Purpose of the investigation
Through the investigation of the present situation of sixth-grade students' composition in our school, we can understand the present situation and mentality of primary school students' composition and find out the root of negative composition mentality. Strive to change the present situation of primary school students' composition, make them have a healthy and positive attitude towards composition, and make composition teaching and new curriculum reform achieve the goal of "educating people" simultaneously.
Second, the content of the survey
From 65438+ 10 to 165438+ 10, the members of our group had a strong interest in the study of the current situation of primary school students' composition. So I used questionnaires, conversations and other ways to understand the situation. Survey contents: 1. Primary school students' basic attitude towards composition; Second, the reason for this attitude; Third, views and opinions on composition teaching methods. Fourth, the views on students' self-evaluation composition. In the survey, 80 questionnaires were collected, 30 Yu Ben students' compositions, diaries and reading notes were browsed, and two studies and discussions were conducted with their peers. The investigation report is as follows:
1, constitute the status quo.
Status 1: Empty and lifeless.
State 2: Expressing lack of emotion.
State 3: The content of plagiarism is the same.
State 4: There is nothing to say and it is difficult to write.
2, psychological performance
One of the manifestations: I am afraid of writing and regard writing as "difficult".
The questionnaire survey shows that about 39.5% students dislike and are afraid of writing.
The second performance: unprepared, lazy and dependent before writing.
These two kinds of psychology are manifested in the whole composition process.
The survey found that most students have no requirement and habit to keep a diary. In the case of five classes in grade six, 25% students want to write, 49.2% are assigned by teachers, 25% write once a week, and 33% write occasionally. In reading, according to statistics, there are still 65,438+00% students who don't read extracurricular books, 27% students sometimes do, 80% sixth-grade students can extract beautiful sentences at the request of teachers, and only 80% students write their own thoughts on reading.
Only 36.4% of the composition materials basically come from their own life accumulation, while more than 63.3% rely on other people's materials.
Performance 3: cope with the exam and be ordered to write a composition.
According to the above survey data, it can be seen that the passive mentality of writing for teachers accounts for the largest proportion of students, and the value of scores is more important than the needs of their own development and communication. In order to get high marks, most students have the habit of reciting their compositions before exams.
Third, the result analysis
To sum up, lack of initiative, lack of interest, lack of self-confidence, lack of passion, lack of true feelings and lack of innovative consciousness are the main manifestations of primary school students' psychological factors in writing. These negative writing mentality seriously affects students' enthusiasm and creativity in writing, which is the main reason why primary school students' writing level can't go up. Focusing on students' negative attitude towards composition, I made a survey and analysis, which is summarized as follows:
1, no communication, no communication.
First of all, composition teaching does not really reflect its essence as a communication tool. It doesn't see that exchanging thoughts and feelings is an important life need for students. It is not based on the need of communication, and it rarely tries to create a "dialogue" between man and society and between man and nature, neglecting to let students have a broad "reader group". If students don't know who they are writing for, they will become a "wall grass" without communication objects, and it is difficult to produce the pleasure and expression impulse when people communicate directly with society and nature. Without this kind of inner emotion and need, composition becomes a compulsory training, and naturally it is "orderly".
Secondly, teachers ignore the emotional communication with students. Teachers don't regard composition as a channel for teachers and students to exchange ideas and feelings, and they don't listen to students' sincerity and wishes. There are things that students don't want to tell their teachers. Composition and life are two skins, so it is naturally difficult to mobilize their life accumulation, stimulate their emotions, touch their hearts and induce their desire to express.
2, composition teaching methods, conservative, closed, not liberated.
As for what to write, how to write and how to write, most teachers lack training objectives, are arbitrary and lack research. Generally speaking, 13 composition class is still a teaching structure of "teacher's proposition-teacher's guidance-student's drafting, praise and correction-teacher's correction-teacher's evaluation". Teachers do not give students the freedom to choose the form of expression. We made a survey of students on "What kind of composition do you like to write", and 68% students chose fairy tales and science fiction stories in six genres: taking notes, writing landscapes, events, fairy tales and science fiction stories. Train the mainstream to adhere to "narrative". It is difficult for a single training form to arouse children's interest in writing; Composition teaching lacks the link of students' self-evaluation and mutual evaluation, instead of guiding students to evaluate their own success or failure, teachers' subjective understanding replaces students' understanding, which makes the composition a mess and makes students feel the joy of success. How do all these bundled teaching stimulate interest, thinking and innovation?
3, do not practice, less accumulation.
First of all, the foundation accumulated in life is weak. It is not necessary for students to observe life, understand life and brew emotions into the composition teaching structure. Composition teaching is closed in a small classroom, isolated from colorful social life and nature. How to learn to experience with heart and cultivate "sensibility"; How to grasp fleeting phenomena and cultivate "catching power" is often neglected. If a teacher doesn't care, students will turn a blind eye to life and be indifferent, and the foundation of life accumulation will of course be thin.
Four. conclusion and suggestion
We believe that it is an important problem to change the present situation of primary school students' composition and make their composition have a healthy and positive attitude. Summing up the investigation and analysis, the fundamental change is to cultivate students' interest in writing; Second, the concept of composition teaching should be updated, the teaching methods should be updated, and the forms should be diversified and open; Third, writing should be closely combined with students' life, broaden writing space and practice more; Fourth, pay attention to the development of students' personality, give more opportunities for publishing works and stimulate students' desire for writing; Fifth, we should strengthen students' extracurricular reading and cultivate students' interest in reading. Sixth, actively guide students to evaluate and correct their compositions and feel the value of their compositions. Only in this way can students' writing ability be fundamentally improved, and our writing teaching can be synchronized with the new curriculum reform to achieve the goal of "educating people".
New survey report 5
First of all, the questions raised
Recently, there are more and more nearsighted students in our class, and most of them wear glasses. Why are there more and more nearsighted people? To this end, I made a survey on the myopia of my classmates.
Second, the survey method
1. Find information on the Internet to understand what myopia is and the reasons for myopia.
2. Look for relevant newspapers or books to understand the dangers of myopia and the ways to prevent myopia.
3. Interview parents of myopia students and some living habits of myopia students.
Three. Investigation and data collation
1, myopia questionnaire for students in this class (omitted)
2. Data collation
(1) The factors leading to myopia are genetic factors, individual factors, environmental factors, nutritional factors and sleep factors.
(2) The main cause of myopia in primary school students: 1, too close to the eyes.
2, the eye time is too long
3. Intensity of illumination light
Step 4 read while lying down
5, lack of sleep
6. The desk does not meet the requirements and the writing posture is incorrect.
7. Effects of radiation in space.
(3) The number of nearsighted students: 22.8% of primary school students, 55.8% of middle school students and 80% of college students are nearsighted.
Four. conclusion
There are many reasons for myopia! Most of the students in this class read books in a dark corner because they spend too much time playing computer and watching TV. As long as these problems are prevented, you will not be nearsighted!
Verb (abbreviation of verb) suggestion
1, do eye exercises seriously and often look at green trees.
2, don't use your eyes for too long, you need to close your eyes and rest for too long.
Never read while lying down, but sit up straight when writing.
We must protect our eyes like life! I wish students who are not nearsighted will never be nearsighted, and those who are nearsighted will not improve their degrees.
