First of all, the questions raised
Now, more and more people around us are beginning to learn English. English has become an important subject. It can be said that the current international language has become English. And can our mother tongue, Chinese, go global?
Second, the survey method:
1, go to the library to consult relevant materials.
2. Get relevant information on the Internet.
Third, investigation and data collation.
1, the number of people who use English and Chinese.
At present, about 400 million people in the world speak English as their mother tongue.
At present, the number of Chinese speakers in the world is about 65.438+0.3 billion.
2. Spelling and pronunciation in English and Chinese.
English spelling and pronunciation are irregular and confusing. There are dozens of ways to pronounce English.
In Chinese, tenses, verbs and adjectives have not changed, and there is no continuous reading. The language is concise, the pronunciation is clear and the speech speed is slow.
3. Difficulties in learning English and Chinese.
Modern English eliminates the complex changes of nouns and adjectives. So the first feature of English is its simple structure, so it is easier to understand and learn.
Although Chinese grammar is not difficult to learn, Chinese characters are relatively difficult to learn. There are many characters with similar shapes and sounds in Chinese characters, and each Chinese character can have many definitions, as well as polyphonic characters. So Chinese characters are difficult to learn.
Fourth, the conclusion.
Through the comparison between English and Chinese, we can find that Chinese grammar is relatively simple, but Chinese characters are difficult to learn. English itself has two characteristics: simple structure and strong expressive ability. This is very convenient for international communication, and it is also a huge advantage compared with Chinese.
Therefore, we can draw a conclusion that if China wants to go global, it will face many practical problems. Therefore, it is difficult for China people to go global.
Cheng Jincheng water in Beijing Xishiku Primary School is a valuable natural resource. At present, about 2 billion people in more than 80 countries around the world are facing water crisis, and more than 300 million people in 26 countries are living in a state of water shortage. China's per capita water resources are in the middle and lower level in the world, ranking127th in the world, which is only a quarter of the world's per capita water resources, while Beijing's per capita water resources are about 300 cubic meters, which is only one-eighth of the national per capita water resources and one-thirtieth of the world's per capita water resources, far below the internationally recognized water shortage limit of 1000 cubic meters. Compared with the early 1980s, the groundwater level in Beijing has dropped by 5? At present, the ground in Beijing is sinking at the rate of10mm to 20mm every year.
Investigation on water consumption of car washing
The car wash shop washes cars with tap water. These car wash shops wash about 20 to 30 cars every day, and some even get as high as 80 cars. The maximum water consumption for washing each vehicle is 50kg, and the minimum water consumption is10kg. If the average water consumption for washing each car is 30 kg, and six car washing shops wash 200 cars a day, then 30 kg× 200 =6 000 kg = 6. According to the calculation, only six car wash shops use 2 190 tons of water every year.
Analysis and discussion
The car wash shop washes cars with tap water. There are more than 600 car wash shops in Xicheng District alone, and the annual water consumption is 1.3 1.4 million tons. It is equivalent to the water of two Shichahai (the water volume of Shichahai is 510,000 cubic meters). There are more than 600 car wash shops in this city. How much 1 3 14 000 tons of water is there every year? This is an incredible number. In addition, the car wash industry has developed rapidly.
Suggestions and measures
1. Radio, television, newspapers, slogans and blackboard newspapers should be used to publicize the serious water shortage in Beijing and enhance people's awareness of water conservation.
2. I hope that the relevant departments will force the installation of the car wash water treatment circulation system.
3. All units should formulate measures to limit the number of times drivers wash cars and educate drivers to wash cars with bottled water.
4. Encourage the development of computerized car washing, and form a scale and network.
5. I hope that the housing management department will install water-saving toilet flushers in residential areas where buildings gather and transform the float height of the old toilet flushers.
Investigation report on students eating KFC
August 2009 14 Author: Yun Qi School: Mao Yisheng Experimental School Class: Class 4 (1)
1, question:
I always hear adults say that KFC is junk food, but I still want to eat it, so I thought, is it harmful for primary school students to eat KFC? If so, how harmful is it? So, I looked into this.
2. Investigation methods:
(1) Learn from the Internet whether it is harmful for pupils to eat KFC.
(2) Learn whether it is harmful for primary school students to eat KFC through newspapers.
3. Investigation and data arrangement:
(1) leads to obesity: the energy provided by a KFC snack is about 1400 kcal, accounting for 88%- 1 13% of the daily supply standard for 3-year-old children and 49%-63% of 13-year-old children. Its fat provides 40%-59% of total energy. Some KFC fast food fats provide about 50% of the total energy, while the vitamin content is less than 10% of the fat.
(2) Damage to children's intelligence: One fried chicken leg is equivalent to the toxin of 60 cigarettes, which not only causes imbalance in body nutrition, but also seriously damages children's brain development.
(3) High carcinogen content: Hamburg, French fries, fried chicken and other foods contain a lot of "acrylamide", which can cause gene mutation, damage the central and peripheral nervous systems, and induce benign or malignant tumors.
4. Conclusion:
Pupils often eat KFC, which is easy to increase blood pressure, blood lipid and cholesterol, and may also be obese, with cardiovascular and endocrine systems such as heart disease, hypertension and diabetes. Frying and baking can easily produce carcinogens, which will cause permanent damage to children's intelligence. Experts warned us: it is best not to eat foreign fast food at night, so as not to cause indigestion; It is not advisable to eat more fried foods, eat more vegetables and fruits as much as possible, and supplement the insufficient intake of vitamins and minerals; Pay attention to the daily diet balance and limit the frequency of eating foreign fast food. Therefore, KFC is harmful to our health, and we should try to eat less or not to eat KFC.

I. Research background:
At present, primary and secondary school students have heavy schoolwork. Besides finishing their homework after class, they either play games or watch TV. The eye burden is very heavy, students usually participate in less sports activities, and their eyesight is not optimistic. To this end, students are organized to carry out eye and vision surveys in the research activities of comprehensive practice network small topics.
Second, the purpose and significance of the study:
According to a joint survey by the Ministry of Health and the Ministry of Education, the incidence of myopia among students in China is close to 60%, ranking second in the world, and the number of students ranks first in the world. The myopia rate of high school students is over 70%, and the number of patients exceeds 60 million. Therefore, it is urgent to popularize eye protection knowledge in similar eyes. Through investigation and study, let students know how important eyes are to their present and future studies. They should pay attention to eye hygiene, do eye exercises seriously, read and write correctly, pay attention to diet and nutrition at ordinary times, and take an active part in physical exercise. At the same time, through the process of operating the computer, master the computer-related operating skills skillfully.
Third, research methods:
1. Students choose and modify the survey items themselves, and the survey items are divided into several groups. The team leader is responsible for the details and the teacher cooperates with the guidance.
2. The eyesight test of the students in Grade Two and Grade Five is obtained from the eyesight files of the school hospital, and then input into the computer for analysis and statistics.
3. Investigate the eyesight of students and their families, and each student should fill out a form for statistics.
4. Collect the knowledge of like eyes about eye structure, common eye diseases and how to protect eyes online.
4. Other investigation methods shall be discussed and formulated by the team leader, and adjusted and implemented at any time.
5. Record activities and archive data.
6. Make all kinds of survey data into computer tabloids and electronic slides, and write personal activity survey experience.
Fourth, the research organization:
The class is divided into eight natural groups, led by the Chinese team leader and the investigation team leader respectively. Specifically, the survey is mainly based on a single team member. Basically, the network equipment in the computer classroom is used to accumulate and sort out data. Teachers organize, coordinate and help provide relevant school statistics and other materials. Teachers also teach computer operation and participate in data collection.
The research process of verb (the abbreviation of verb);
I. Project investigation
1 and the situation and analysis of students' eyesight test in grade two and grade five in 2004.
2. Investigation on the amount of homework and the completion time of grade five students in one day.
3. Investigation on the accuracy of students' writing posture and doing eye exercises.
4. The myopia degree of students wearing glasses, the proportion of students and the price.
5. Requirements of classroom lighting in schools (online), and investigation and analysis of the lighting situation in our school.
6. Statistics on the average time of watching TV in a day.
Second, understand the eye structure and the causes of myopia:
1. Find information on the Internet to understand the eyeball structure.
2. Find information online to understand the causes of myopia.
3. What measures and practices are there to prevent myopia?
Research results of intransitive verbs:
1. Students submit a computer tabloid and the group completes a PPt slide.
2. The investigation team compiled two computer tabloids, two PPt slides and wrote two investigation summary reports. (including the summary report of computer usage survey).
3. A copy of the students' experience and suggestions in completing the activity.
Seven. Conclusions and recommendations:
Through this survey, we have come to such a knowledge: I know that poor eyesight is a common disease that affects students' physical and mental health at present, and if it continues, it will inevitably affect the health quality of our Chinese nation. Eyes are so useful that we cannot live, study and work without them every day. Every child knows that he can't see anything without eyes. How can he make due contribution to the "four modernizations"? We really think we should take good care of our eyes.
1. We find that indulging in video games is very harmful to eyes and body and mind. The students said that in order to do eye exercises seriously, they should always keep the writing posture of "one punch, one foot and one inch", wash their hands before and after meals, keep a good lighting environment, and don't watch more TV. Read for an hour or so, have a rest, or look away for a while.
2. We should do the Three Don 'ts:
(1), don't read or write in dim light and direct sunlight.
(2) Don't walk or read in bed in a bumpy carriage.
(3) If you have any questions, you can go online to find the information you need. You should look for more information, don't always play games, and be sure to protect your eyes. In short, there are many things to do, classmates, let's protect our eyes together!
Zhou Hongyang, a classmate of Class 5 (2), suggested that to change the bad habit of students indulging in games, they could try to make a small game by themselves. Isn't this much more interesting than playing games? Try flash, if you learn it, then animation and small games are not a problem. This is really interesting. Can you believe it? Xu Qianqian of Class 5 (3) suggested that schools can also engage in activities about food nutrition, because many students like KFC and McDonald's now, but they don't like vegetables, so they don't pay much attention to food nutrition, so I hope that through this activity, students will realize the seriousness of not paying attention to food nutrition.
In a word, three classes in grade five conducted a survey of eyes and eyesight in the comprehensive practice research of network, from which we know a lot about protecting eyes with eyes. At present, students' eyesight is not optimistic, and we still have a lot to do.
In practice, we carried out activities through computers and networks, which broadened our horizons, improved our abilities and gained a lot of knowledge.
I hope it helps you, hehe. But you can't copy every article. You should have your own imagination.

Myopia:
According to the survey, there are more than 5 million blind people in China, and the number of people with low vision is nearly10 million, especially children and adolescents, and the prevalence rate is extremely high. According to the latest data from the national student physical health survey, the incidence of myopia in primary school students, middle school students and high school students in China is 22.78%, 55.22% and 70.34% respectively. What's even more shocking is that a survey report says that there are more than 300,000 people who are blind due to high myopia in China. Therefore, students, parents and society pay more and more attention to the prevention and treatment of myopia in children and adolescents. Why are there more and more nearsighted students? What should students do with myopia? Is it just caused by bad eye habits? In order to understand the myopia of primary school students and the related factors that cause myopia, I made a survey on some students in our school.
Second, the questionnaire
1. Are you nearsighted?
A.yes, b no.
2. Why are you nearsighted? (Don't answer unless you are nearsighted)
A, watching too much TV B, sitting improperly C, others
How nearsighted are you?
A./kloc-below 0/00, below B. 500, above c.
Third, investigation and analysis: the causes of eye myopia:
Most people usually don't pay attention to protecting their eyes, which leads to myopia. The results show that myopia is the adaptive change of human eyes to the contemporary environment, and its occurrence and development are closely related to the increase of eye activity environment and the imbalance of nutrient intake. Improper use of eyes and inattention to eye hygiene (such as watching TV and surfing the Internet for too long) are the main reasons for the sharp increase of myopia in modern children.
1 Watching TV too close.
Watching TV for too long
The picture density of TV is too deep.
4 posture is not correct when doing homework.
Read a book in too strong sunlight
6 reading in weak light.
Sitting in front of the computer for a long time
8 unreasonable diet
9 observation laser
10 reading in the carriage
1 1 genetic factors
12 not doing eye exercises seriously
Fourth, the survey results:
Through investigation, it is found that the myopia rate of middle school students is on the rise, but middle school students do not pay attention to this phenomenon. Some people even think that they are nearsighted, just wear a pair of glasses. It doesn't matter if you are nearsighted. Many people often blame it on bad eye habits, such as improper reading distance, too dim light, long-term eye use and so on. However, medical research in recent years shows that unbalanced diet, lack of sleep and noise are also important factors that induce myopia in adolescents.
Verb (abbreviation of verb) suggestion
(1) When reading, the posture should be correct and the light should be sufficient. When reading and writing, sit one foot away from the desk, keep your chest away from the desk and your eyes away from the textbook.
(2) Don't read while riding or walking, and don't read while lying down. Read and write 1 hour, overlook 10 minutes, or go outdoors to adjust your eyes and muscles.
(3) Insist on doing eye exercises for ten minutes between classes.
(4) Try to surf the Internet or watch other radioactive things as little as possible. Pay attention to the schedule and don't let your eyes be tired for a long time.
(5) Don't be partial to food, eat less spicy food, and eat more foods containing vitamin C and vitamins A and D. ..
(six) to the ophthalmology department for regular examination, listen to the doctor's guidance, and gradually correct vision or prevent myopia from deepening.
Sixth, experience
In order to effectively prevent myopia and other eye diseases: first, we should develop good hygiene habits, eat reasonably, exercise and ensure physical and mental health; Second, we should correct bad habits and develop good eye hygiene; Third, we should regularly check our eyes in eye hospitals, especially patients with high myopia, and find eye diseases in time, so as to achieve early detection and early treatment. Vision is related to our life. We should take good care of our eyes and don't let us regret it later!
My home is only half as big as it is now. There is a living room and a bedroom, where I spent my childhood. My memory of that time is vague. According to my mother, there is only a small color TV, a small refrigerator, a semi-automatic washing machine and a fabric sofa at home, which burns honeycomb coal ... This is a simple and warm home. Now let me show you around my new home:
My new home has a big living room, two bedrooms, a study and a small storage room. I used to live in my parents' bedroom, but now I have my own world. I have the right to decorate my warm little world: my sheets, bedspreads and curtains belong to Winnie the Pooh, and my wardrobe is full of my clothes, as well as bookcases and desks. I call this place "Happy Learning World". Those posters revealed my innocence and happiness. I have a piano and I am immersed in the world of music every day. I am intoxicated with both sadness and joy. I gradually got some teddy bears, and I would tell them my legendary story every night. There is a big TV, leather sofa, rocking chair, big bookcase in the living room, and many shells I picked up in Hainan … Do you think my home has changed?
Four. conclusion
From bad to good, people don't want it, but it takes generations of efforts to change it. Let's study hard and make my country happy!
