Reject mileage anxiety, three 250,000-class new energy SUVs are recommended

Under the tide of new energy, I believe that many friends have replaced their cars with pure electric models. Indeed, unlimited travel, low car costs, and comfortable driving experience make people immersed in it, but the inability to cope with long-distance and inconvenient refueling cause mileage anxiety, which are also practical problems, which are torn. In fact, for friends who want to enjoy various related conveniences of pure electric models and are afraid of mileage anxiety, various manufacturers are currently promoting new plug-in hybrid/range-extended electric models, which is a more balanced choice at present. This time, we are in the budget range of the most mainstream new energy model purchase, and we bring you three models that can refuse mileage anxiety. BYD Frigate 07, Geely Xingyue L Range Extended Electric Edition, and AITO Ask the World M5 to find out.

From the debut to the listing, the BYD Frigate 07 can be said to have been preheated for a long time. As a new medium-sized SUV of BYD Ocean Network, the popularity of the Frigate 07 goes without saying. The new design style, the full series of large 5-seat layouts, and the DM-i/DM-P plug-in hybrid system are added. This is not a wrong choice. The Xingyue L Extended Range Electric Edition has three driving modes: Extended Range, Pure Electric, and Hybrid. It is a veritable all-round player. In the Extended Range Mode, the WLTC service life of the Xingyue L Extended Range Electric Edition can reach 1250km, and there will be no mileage anxiety at all. AITO Qinjie M5 has become a dark horse player among new forces with its Hongmeng cockpit. As a new energy model with a mature range-extending power system, excellent driving experience, and a leading intelligent cockpit experience, the Q-5 is worth looking forward to.

Appearance: Different styles to meet different aesthetics

At the design level, the three cars show a completely different design tone. The frigate 07 adopts the new style of BYD Ocean Network. The new ripple-type center net, sharp light set and BYD’s luminous LOGO show a new look different from the previous BYD, with an excellent sense of novelty; the Xingyue L Extended Range Electric Edition is a "good man at home" style, with straight lines and smooth contours, giving people a reliable and practical sense of vision, which belongs to the traditional aesthetic good-looking; the M5 is a typical sports style, with very smooth lines in the front body, and the overall visual center of gravity is low, and the posture is moving.

In the rear part of the car, the three cars use the current popular through-type light group at the same time. The design details of the frigate 07 light group are innovative, and the swirling structure of the waves on both sides can show the effect of welcoming light when the vehicle is unlocked. With the connecting guide tail above, it is full of personality and recognition; the overall rear of the Xingyue L range-extended electric version is still a stable image of Fangzheng, and under the integration of the slender light strip, it does not appear dull; the rear part of the M5 is still round and full, but the design is relatively ordinary, and there is no obvious recognition.

Although the three cars were positioned differently, it was not difficult to see that the size and body were not very different, and they were almost the same level. This showed that the Star L extended range electric version was a bit low in positioning and misplaced in competition. In fact, due to differences in design, the Q M5 had the smallest sense of visual volume among the three cars, but in terms of intuitively affecting the wheelbase of the driving space, it was the most advantageous one among the three cars.

In terms of tire specifications, the frigate 07 uses 20-inch wheels, while the Star L Extended Range Electric Edition and the M5 both use the mainstream 19-inch wheels of the same class, larger size wheels and the most advantageous body length and height. The visual effect of the frigate 07 is undoubtedly more atmospheric.

The three cars are all models priced 200,000 or more by Chinese brands. There is no need to worry about the basic configuration level. Everything is available, but there are differences in details. Specifically, on the keyless entry and multi-layer sound insulation glass with high daily practicality, the performance of the M5 is relatively strong. The other two cars are only equipped with the function of the front row. It is standard in the whole car and has obvious advantages. In addition, for a medium-sized SUV with a small size, the induction trunk is a configuration that can obviously improve the convenience. Among the three cars, only the frigate 07 is not equipped, and the daily experience is different.

Interior: Technological atmosphere

At the interior level, most of the functions and operations in the three cars are integrated into the central control large screen, creating a strong technological atmosphere. The frigate 07 and the interrogator M5 use a central control floating large screen design, while the Xingyue L is a cross-screen design. Among them, the Xingyue L is uniquely equipped with a co-pilot entertainment screen, which allows the co-pilot passengers to spend time better during long-distance journeys.

In addition, the lining materials of the three cars are very high-grade, and a large area of soft leather wrapping is a common feature. However, for the trend of air conditioning, electronic shift lever and speaker shape, Xingyue L Extended Range Electric Edition and Qjie M5 are too flat, while Frigate 07 is obviously more design sense.

In terms of interior configuration, the performance of the three cars is satisfactory, reflecting the configuration level of a Chinese brand SUV priced at more than 200,000. Specifically, in terms of comfort configuration that everyone cares about, the M5 is better than the M5. The rear seat heating, 15-speaker audio, and 128-color ambient lights are all unique configurations. It is also the only model among the three cars to provide seat massage options, maintaining a leading position in the three dimensions of touch, hearing and vision. Xingyue L Extended Range Electric Edition and Frigate 07 come and go, regardless of height.

At the level of intelligent configuration, all three cars have performed well. The frigate 07 still adopts the standard solution of BYD’s smart cockpit, with a rotating large screen and high-speed 5G network, which can provide an excellent human-machine interaction experience; the Xingyue L extended-range electric version has a solid "stacking material", Qualcomm 8155 chip + three-screen interconnection, and every passenger in the front row can enjoy a rich experience of scientific and technological functions; the main selling point of the M5 is the Hongmeng cockpit. Hongmeng’s strong ecosystem and convenient interaction pattern are very attractive. Overall, the Xingyue L extended-range electric version is still slightly better. After all, with an extra large screen, the satisfaction of the passenger riding experience in the car is also more complete.

Performance: Meet daily use and solve mileage anxiety

The three new energy models can be divided into two technical routes in terms of power system. The Frigate 07 and the Xingyue L extended-range electric version use a plug-in hybrid system, while the Qinjie M5 is an extended-range power. The power performance of the three vehicles is completely no problem for daily household use, and the combination of oil and electricity can achieve a relatively exaggerated value, which has obvious advantages over pure electric vehicles and fuel vehicles.

The M5 is the only model with a rear-mounted rear-drive layout among the three cars. Coupled with a more powerful motor, it will have an advantage in terms of driving pleasure among the three cars. The Star L Extended Range Electric Edition can achieve seamless switching of three driving modes: pure electric, extended range, and plug-in through the three-speed DHT gearbox. Its pure electric cruising range is also the longest among the three cars, and the fuel economy during the use of the car is better. The DM-i system of the Frigate 07 is more standard in all aspects.

Space: There are differences in experience

In terms of riding space, the wheelbase of the three cars is more than 2.8 meters, and it is a large five-seat layout. Specifically, the 1.78-meter-tall experiencer enters the rear row of the Xingyue L Extended Range Electric Edition and the Q World M5 respectively (the front row is his driving position), with two punches and one punch and three fingers respectively, and the head space is more than one punch; the 1.8-meter-tall experiencer enters the rear row of the frigate 07, and there is still more than two punches in the legs, and the head space is also more than one punch. Overall, the rear row of the three cars can leave a relatively ample space for passengers, with the frigate performing the best, while the longest wheelbase of the three cars, the Q World M5, lags behind in the rear legroom, which makes some differences.

In terms of trunk space, the interior of the three models is relatively regular, among which the wheel arch of the frigate 07 is more obvious, and the lateral space is limited. In terms of expansibility, the rear seats of the three cars all support 4/6 ratio reclining, and after reclining, they can form a flat state with the trunk floor, and the load capacity is satisfactory. In addition, the three cars are equipped with electric tailgates, of which only the frigate 07 does not support induction opening, and the convenience in daily use is not as good as that of the Xingyue L Extended Range Electric Edition and the Q-Realm M5.

Security: All are equipped with rich active security configurations

As the commonality of "electric shock" models, all three cars have a wealth of active safety configurations, including rare door opening warning and forward collision warning, which can maximize safety protection regardless of driving or parking. Specifically, there are only a small number of configuration differences in the three cars, among which the most abundant is the Xingyue L Extended Range Electric Edition, which is only not equipped with fatigue driving function, and other aspects are almost at the level of filling the configuration table; while the performance of the Frigate 07 and the M5 is similar, slightly inferior to the Xingyue L when the price is similar.

Summarize:It can be found that although the core satisfaction of the three new energy SUVs recommended this time is to solve mileage anxiety, their respective characteristics are still very clear, and they will not be a moderate experience at all. The AITO M5 is a very obvious sports orientation, including power layout, performance and design style, which is very suitable for users who have certain requirements for control; if you have extreme requirements for fuel consumption and battery life, then the Geely Xingyue L range-extended electric version that seamlessly switches three power modes meets your needs; the DM-i system is very mature and has excellent user word-of-mouth feedback. The BYD Frigate 07 is the choice to ensure that there will be no mistakes. Combined with your own car needs and brand preferences, I believe you can find your favorite car.

"My Agent Grandpa" reveals new trailer, Samuel Hung saves Loli’s bravery and invincibility


    1905 movie network news Directed and starred by Hong Jinbao, the film produced and specially starred by Andy Lau will be released nationwide on April 1. A few days ago, the film released a "heavy attack" version of the trailer. In the trailer, Hong Jinbao is strong and close combat is lethal, but in addition to the halo label of "retired old agent" and "Central Security Bureau", "agent grandfather" also shows a surprising "cute" side.

    Along with the trailer, there is also a set of character relationship posters. "Agent Grandpa" Hong Jinbao, "Prodigal Son Father" Andy Lau, and the rebellious and naive little girl Chen Peiyan are naturally the "strength responsibility" of the film. The three "old urchins" of Xu Ke, Mai Jia, and Shi Tian have become the "comedy responsibility" of the film; Zhu Yuchen, Feng Jiayi, Hu Jun, Feng Shaofeng, Peng Yuyan, and Yuan Biao six stylish men collectively become the "appearance responsibility". All the big coffee people support "Agent Grandpa" and conquer the audience with their strength, acting skills, and appearance.


Hong Jinbao exposes that "if you can play, you can act better"


    In "Hong Jinbao", he plays a retired agent Lao Ding. Although he is over 60 years old, his physical fitness is still better than that of many young people. But what stands in sharp contrast to his vigorous skills is his inadvertent "cute" character. In the trailer, Lao Ding uses the secret agent’s stunt when unlocking the lock, but forgets that the house key is hanging around his neck, but the landlord’s aunt Li Qinqin’s expression during the conversation is also embarrassed and a hint of shyness. At the end of the trailer, the little girl Chen Peiyan points out the fact that the landlord loves him, and the shot of Hong Jinbao spitting out a mouthful of water also makes the audience shout "This grandpa is so cute".


"Agent Grandpa" comes with black humor, and Tsui Ke Maijia Shitian transforms into "comedy responsibility"

    In the trailer exposed this time, Feng Shaofeng plays a doctor who is doing a health check for Lao Ding played by Hung Jinbao. He first diagnoses worriedly, "The liver is not very good, it’s a little hard, the kidney is not very good, let’s cut it, and the heart is not good…" Then he changes the wind and says, "Just kidding, your body is better than many young people." While relieved, he can’t help but smile. When the little girl chatted, he said, "Lao Ding, are you the most powerful old man in the world?" After Hung Jinbao blew up all his opponents, he casually responded, "What do you think?"

    The three all-rounder seniors, Tsui Hark, Maijia, and Shi Tian, this time became "comedic responsibility" in the movie, playing the three most "ordinary" old men, sitting on the street all day chatting about mountains and gossiping, which is quite funny; especially Tsui Hark, although he did not say a word in the trailer, his style and expression formed a strong "contrast" with the daily serious and domineering director image.

    "My Agent Grandpa" co-starred Hong Jinbao, Andy Lau, Zhu Yuchen, Li Qinqin, Feng Jiayi, Chen Peiyan, Hu Jun, Feng Shaofeng, Peng Yuyan, Song Jia, Mai Jia, Shi Tian, Yuanbiao, Yuanqiu, Yuanhua, Yuanting and Yuanbao. The film will be released in major theaters on April 1.

Driving industry white paper: As an emerging profession, driving full-time monthly income has exceeded 10,000

  Xinhua News Agency, Beijing, August 9 (Reporter Xu Rui) The research team of the Public Law Research Center of Tsinghua University Law School released the "White Paper on the Development of the Driving Industry" (hereinafter referred to as the "White Paper") on the 8th. The "White Paper" shows that since 2016, the demand for driving services and market scale have grown rapidly. Last year, the total order of the national driving industry has exceeded 253 million orders, and the total output value has reached 15.40 billion yuan.

  According to the White Paper, drunk driving is still the largest usage scenario for users, accounting for 97.8%, followed by work fatigue, business transportation, and family transportation. While the concept of "driving without drinking, drinking without driving" has been deeply rooted in the hearts of the people, the value of the driving industry has also been fully reflected. It is estimated that the driving industry reduced the number of traffic accidents caused by drunk driving 3.50 million last year, exempting 830,000 from criminal law sanctions, and reducing property losses by 46.20 billion yuan.

  The white paper also shows that chauffeur driving has become an emerging professional position, becoming the main source of income for many families. According to the data, the average monthly income of full-time chauffeur drivers in the country is 6,957 yuan, and the income of full-time chauffeur drivers in cities such as Beijing, Shanghai, Guangzhou, Shenzhen and Hangzhou is more than 10,000 yuan.

  In recent years, local traffic police departments have been actively exploring new methods to manage drunk driving, and "Internet + driving" has become an important breakthrough point. Represented by platforms such as Didi Driving, the driving industry has formed a new economic format, and has become an effective means to manage drunk driving and reduce traffic safety accidents. Didi Chuxing relies on massive data and intelligent transportation cloud computing platform to mine and apply big data in the field of driving to provide technical support for governing drunk driving and managing urban road traffic.

  In March this year, Didi cooperated with Shenzhen traffic police to launch a new "smart transportation + drunk driving governance" method, using Internet big data, high-tech algorithms, and "Internet +" methods such as real-time heat maps to try new effective governance measures in drunk driving intervention and drunk driving law enforcement.

  Last month, Didi’s "Diyu · Xingcheng" heat map has been used by traffic police in 12 cities across the country, including Nanjing, Wuhan, Qingdao, Guangzhou, etc., in daily work to control drunk driving.

  "With the Xingcheng system, we combine the traffic flow and past law enforcement experience of the traffic police to more accurately control the trend of drunk driving in the city, optimize the location of the investigation and punishment of drunk driving and the time of the police, and accurately crack down on drunk driving, saving a lot of police and material resources." Jinan traffic police official said.

  Cheng Wei, founder, chairperson and CEO of Didi Chuxing, introduced that since its establishment in July 2015, Didi Driving and the traffic police departments of 51 cities have carried out anti-drunk driving related activities, more than 118 times, including road Security Training, drunk driving activities, public welfare activities, anti-drunk driving alliance, etc., and actively promote the "anti-drunk driving" concept.

Getting out of the misunderstanding of labor education practice: "gamification" can’t gain labor interest

  Bright pictures/vision china

  [thoughts]

  editorial comment/note

  Labor refers to the activity that people create material wealth and spiritual wealth necessary for their own survival and development through their own hard physical or mental efforts. In the new era, labor education has been picked up again, and schools have gradually begun to jointly carry out labor education practice with society and families. But in reality, labor education is often reduced to a simple task in daily teaching, a simple physical education, skill learning, and even alienated into entertainment, punishment and domestication. This paper holds that the lack of understanding of the connotation of labor and labor education still leads to some misunderstandings in the practice of labor education, such as the "servitude" of cognitive mental work that makes learning and labor oppose each other, the "play" that replaces the real pleasure of labor, and the lack of continuity in labor education, which needs serious reflection based on the connotation of labor education, and has certain practical pertinence, hoping to bring inspiration to readers.

  1, learning "servitude" put learning and labor in opposition.

  In recent years, labor education has been promoted to the same position as moral education, intellectual education, physical education and aesthetic education, so some schools have vigorously carried out labor education practice. Some open up schools to build farms and guide students to carry out productive labor practice; Some combine social resources and rely on labor education practice bases to organize students to experience labor. Social practice activities of learning agriculture and learning industry are carried out regularly every year in many places. However, while increasing the opportunities of labor experience, we will find a conventional concept that students’ daily study is not labor. This is really worth reflecting on. Isn’t learning itself labor?

  In fact, learning itself is also a kind of labor, and learning is cognitive mental labor. Soviet educator Suhomlinski believes that "labor education begins when students sit behind desks and study. Desk is the most complicated machine tool, which makes children, teenagers and teenagers feel that it is shameful to be careless, and laziness and idleness are sad. It is the most difficult thing for students to establish this understanding in education". Learning is a kind of labor that promotes the combination of wisdom and hands’ efforts. In this labor, learning is labor, while knowledge is the result of labor efforts. Under the background of digital labor era, the function of labor gradually turns to the existential function of realizing personal self-worth and obtaining the sense of value and meaning of existence. From this perspective, completing labor outside of learning may not be able to obtain more sense of value and existence than learning process.

  If learning is labor, why talk about labor education now? Why didn’t the mental work, which occupies the main position in students’ life at present, achieve the purpose of labor education? Why do schools often oppose mental labor and productive labor, and think that too much emphasis on intellectual development leads to insufficient labor experience? This is because the mental work of learning is alienated, and learning has been externalized as "labor".

  To recognize that learning is externalized as "labor", we need to trace back the essence of learning, a mental labor, and re-examine the current learning process of students. From Marx’s definition of labor, we can see that labor is first of all a process between man and nature. In the process of material exchange with nature, man is increasingly aware of the common attributes of things and phenomena, and finds the regularity and connection between them, while mental labor is expressed in the form of representation, concept and reasoning. Learning this mental work ultimately points to scientific understanding of things, which is also an essential attribute for learning to become mental work. At present, students’ learning has gradually become "externalized labor" pointed out by Marx. Marx said in the Manuscript of Economics and Philosophy in 1844: Labor is an external thing for workers. In labor, he does not affirm himself, but denies himself. Instead of feeling happy, he feels unfortunate. Instead of freely exerting his physical strength and intelligence, he tortures himself physically and mentally. Once the external force stops, he will escape from labor like a plague. This exposition of externalization of labor seems to be just right to describe the study of today’s students. Students’ study is not to scientifically understand reality, but to pursue external material needs. The "tearing books after the college entrance examination" repeatedly exposed by the media reflects the students’ escape from this externally imposed task. Therefore, learning is no longer real labor, and it no longer has the function of liberating physical strength and intelligence.Instead, it becomes "hard labor", so it has little effect on improving students’ labor literacy.

  2. "Gamification" makes students lose their interest in labor.

  Corresponding to the fact that learning has become "hard labor", other forms of labor education that are gradually emerging show a trend of "gamification". Some schools carry out interesting and wonderful labor activities to attract students, and some schools integrate labor education into spring outing. On the one hand, this can improve students’ enthusiasm for participating in labor, but on the other hand, we need to pay attention to avoid blurring the difference between labor and games. Labor is the process of externalizing oneself, while game is the process of internalizing reality. The fuzziness of the difference between labor and games is more obvious in the digital age. Digital labor blurs the time-space boundary between entertainment and work, and dispels the traditional antagonistic relationship between play and labor.

  Labor is a serious process of giving, and the joy of labor lies in creation. This kind of giving also explains the self-externalization of labor. Students devote their physical strength and intelligence to the labor process and gain certain results. The pleasure that students feel in their work is the pleasure of creating things because of self-sacrifice, not fun. There is a difference between labor and games. Games can naturally bring satisfaction to children, but labor itself has no interest in children, so the interest in labor needs to be cultivated and developed consciously. The gamification of labor makes many activities look interesting, but there is no labor in essence, and students can’t gain interest in labor. Suhomlinski believes that the interest in labor should be manifested as "they realize that they can act on nature, make plants give fruits, and use tools to process wood or metal into needed shapes". Therefore, in the practice of labor education, we need to judge whether the interest in the labor process comes from giving and creating, or is interfered by other factors such as gamification.

  The contribution in the process of labor can cultivate positive labor values and make students love the working people and respect the fruits of labor. At the end of the 19th century, a "new" school appeared in France to train people engaged in "advanced knowledge occupations". In this school, students treat manual labor just like games and sports, because they don’t have to live by manual labor in the future. Although this school is located in the countryside, the students are far away from farmers’ lives. Although they are also working, they can’t really understand and study various social relations. Rousseau believes that only by taking part in labor in person and understanding all its complexity and arduousness according to experience can students judge the social significance of a production department in the future. Therefore, if we don’t regard labor as a serious process, we can’t cultivate our feelings for the working people, and we can’t cultivate our appreciation for the obtained survival materials.

  3. Labor education stays in experience and ignores daily self-service labor.

  At present, the labor practice of studying industry and agriculture in some areas is vigorously carried out, and an institutionalized labor experience system is gradually formed based on the construction of learning industry and agriculture bases. However, the persistence of these activities is worthy of attention. Most schools spend one week each semester leading students to experience labor, but they only stay in the experience once each semester, and there is a lack of cohesion between the activities, which is easy to make the labor experience become a casual entertainment. What’s more, some schools organize students to pull weeds in wasteland, and students regard pulling weeds as a kind of hard labor. This kind of labor experience of "working without teaching" deepens students’ rejection of manual labor. Therefore, the experience of labor must be complete, so that students can see the results of labor and feel satisfied with the achievements they have made through their own labor. If we just stop at pulling weeds without letting students experience the significance of pulling weeds for the growth of saplings, it will be difficult for this labor experience to play its due role. To lead students to plant wheat seedlings, we should let them see the process of wheat seedlings growing, heading and harvesting, and even let them see the process of wheat grains turning into food. At this time, the sense of pleasure comes not only from obtaining external products, but also from experiencing the sense of value and existence of labor.

  In fact, daily self-service labor is just the way to implement the principle of continuity of labor education. However, these are often ignored in schools and families. Schools spend time and energy to organize off-campus labor practice, but at noon, catering staff bring students lunch to the classroom, "depriving" students of the opportunity to experience self-service. The relationship between man and self is at the core of the three attributes of man, which also means that students’ self-service labor plays a vital role in students’ all-round development. Self-service labor can be regarded as the beginning of labor education. No matter what kind of productive labor he is engaged in in in the future, self-service will become his obligation and habit, and it is also the habit of cultivating people to observe discipline, meet their personal needs by doing it themselves, and form the habit of respecting others. When students get food effortlessly, it is difficult to ask them to respect food and labor.

  4. Strategies and suggestions for getting out of the misunderstanding of labor education practice.

  "If there is labor, there may not be education". Labor needs to satisfy three relational attributes, namely, man and self, man and nature, and man and society. The basic contents of labor are: self-service labor, productive labor and social welfare labor. Labor education is a practical activity based on physical labor and material production labor, exploratory innovation labor and artistic aesthetic labor, which is manifested in independent life in family life, practice and hands-on operation in study, public welfare activities in society and various professional labor. Therefore, the strategy to get out of the misunderstanding of labor education practice is to balance people’s different forms of labor demand through diversification.

  First of all, set up a cohesive and comprehensive labor education course. Dewey once said in The Waste of Education that all aspects and stages of education lack the necessary connection and cohesion with each other, which leads to conflicts and even negative effects. Similarly, in order to avoid the waste of education caused by labor education staying at the experience level, the labor education curriculum needs to pay attention to the cohesion of labor content and skills, which is reflected in the cohesion of curriculum content and the cohesion of education system. In terms of course content, it is necessary to set up labor courses that echo and connect properly according to the needs and characteristics of students of different classes and grades. In the education system, it is necessary to consolidate the skills and concepts of labor education through the cooperation between family and society. Schools can encourage students to find service jobs at home, take the initiative to participate in housework, and learn some labor skills. In addition, the content of labor curriculum also needs to take into account three basic labor education contents, namely, self-service labor, productive labor and social welfare labor.

  Secondly, change the concept of labor education of parents and educators, so that parents and educators can establish labor education awareness. The promotion of the cooperative mechanism between labor educators and schools puts forward higher requirements for teachers and parents’ awareness of labor education. For example, some schools will arrange "homework". If teachers and parents can’t pay attention to it, the effect will be greatly reduced. In order to avoid staying in the curriculum, labor education needs to enhance the awareness of teachers and parents. On the one hand, it is necessary to interpret the connotation, function and significance of labor education in combination with the development of the new era. On the other hand, it is necessary to change the concept of labor education through necessary education and training, so that they can voluntarily carry out and cooperate with the development of labor education activities.

  Finally, actively develop creative forms of labor and promote the combination of physical strength and brain power. Creative labor enables students to use the power of wisdom in physical labor, realize the unity of "internal thinking" and "external doing", and thus experience the happiness of labor. Wang Shaoliang, a scholar, believes that the labor values of contemporary teenagers have changed from "labor glory" to "labor happiness", that is, from "a kind of praise obtained from the outside through labor achievements" to "confirmation and affirmation of an essential force from their own labor achievements". Therefore, the development of school labor activities can not stay in simple physical labor, but needs to develop challenging creative labor that can show students’ physical and mental potential. Suhomlinski’s "creative labor theory" also points out that the content of labor education should be enriched with enough knowledge, abundant wisdom and refined talents.

Why is it that Beijing has not seen snow this winter for the first time since 1970?

    Yesterday (2nd) at 3pm, in the consultation room of Beijing Meteorological Bureau, all kinds of cloud pictures and data were constantly switched on the big screen, and several analysts told their forecast views one by one before going on stage. Since the beginning of winter, except for two small-scale snowfalls in the outer suburbs in December 2008, almost no snow has fallen in Beijing, which makes the Spring Festival in 2009 less of a landscape and adds a little disappointment to people who are looking forward to the snowy scene.


    Tomorrow is beginning of spring, and the Lantern Festival will be held in a few days. Will there be a "timely snow" coming to Beijing? Why is it difficult to snow in Beijing this winter? Our reporter interviewed Sun Jisong, the chief forecaster of Beijing Meteorological Bureau, to dispel doubts and doubts about snow.


  Northwest airflow sings "one-man show"


  Cause a winter without snow


    Cloudy and sunny-the sky over Beijing is still calm. According to the forecast of Beijing Meteorological Observatory, the weather will be mainly sunny to cloudy this week, and the highest temperature will reach 10 degrees Celsius. Tomorrow will be beginning of spring, and in the more than 100 days since October 24th last year, there have been only two snowfalls in Yanqing in the north and Pinggu in the northeast-December 10th and 23rd, 2008. In the urban area of Beijing, there is still no effective snowfall. Only sporadic snowflakes appeared on December 10 last year, but they were fleeting and the precipitation was only 0.1 mm.


    "This year’s situation is rare, but it is also normal." Sun Jisong, chief forecaster of Beijing Meteorological Observatory, said that historically, the winter precipitation in Beijing has not been large, and the precipitation from December to February of the following year is usually about 10 mm, so it cannot be said that there is no precipitation in winter. Tracing back to history, the last winter with almost no precipitation was in 1970. However, since October 24, 2008, there has been no precipitation in the urban area this winter, which is really rare.


    A report in Sun Jisong’s hand shows that water shortage is not confined to Beijing. This winter, droughts occurred in Hebei, Shanxi, Henan and other places. According to media reports, the current drought has a wide range and a long duration, which is basically rare for many years.


    "It should be said that there is no direct connection between no snow and warm winter." The computer in the consultation room shows that daily maximum temperature in some urban areas of Beijing has exceeded 10 degrees Celsius in the past two days. However, Sun Jisong said that in addition to cold air, the formation of snowfall must have water vapor transportation and appropriate ground temperature, and several factors are indispensable. However, there is no snow this winter, and the main reason is water shortage-the water vapor transportation has been "broken".


    Sun Jisong introduced that from the perspective of Beijing, water vapor mainly comes from two channels. One is the water vapor brought by the southwest warm and humid airflow from the south of the Yangtze River, especially the snowfall, which often has the characteristics of large snowfall and long snowfall time, and often becomes the "main force" factor of snowfall in Beijing; The other source of water vapor is the water vapor brought by the easterly airflow from the Bohai Sea and the Yellow Sea. However, due to its short transport length, its snowfall is characterized by a small amount of snow.


    Since December last year, there have been four cold waves sweeping the city, but all of them are mainly cooled by strong winds. "This winter, the northwest wind is mainly prevalent in Beijing, which is not conducive to the transportation of these two streams of water vapor. However, the easterly wind or southwest wind formed occasionally through the change of atmospheric circulation has basically not formed this year, so the water vapor transportation has basically been broken. " Sun Jisong said that the Chibi-style "sudden change of the wind and cloud" is pitiful, and it has not been encountered once this winter, which can be said to be "reasonable and unexpected".


    Investigate and dispel doubts


  Four conjectures about "No Snow"


    Conjecture 1


  Is it possible to snow on the fifteenth day of the first month?


    On the sixth day of the Lunar New Year’s Eve, in a ski resort in Mentougou, Mona Lee skated with several friends. The only thing that made him regret was that the mountains beside the ski resort were bare. "I can’t even take a picture of Zhang Xuejing. There is no snow outside the slide. It is artificial at first glance."


    In many people’s minds, snow and Chinese New Year are inseparable. If there are no snowflakes, the taste of the year will be much less. In the snow-free winter, can we make up for everyone’s regrets at the Lantern Festival? Sun Jisong, chief forecaster of Beijing Meteorological Observatory, said that such a wish may be difficult to realize. From the analysis of the current data, it is unlikely that it will snow in the next ten days or so, that is, during the Lantern Festival.


    "But we can’t say that there is no hope at all." Sun Jisong said that due to the rapid change of atmospheric circulation, there may be changes, but from the whole circulation background, it is difficult for water vapor in the south to reach Beijing. There may be a small amount of precipitation in central and southern Hebei and southwestern Shanxi. "But if snowfall wants to come to Beijing, I am afraid it is still difficult to achieve."


    Conjecture 2


  "Sequela" of Meteorological Intervention?


    "More than a thousand rockets were fired at the opening ceremony of the Olympic Games to eliminate the rain. It won’t eliminate all the rain in a year, will it?" Some netizens questioned whether large-scale artificial intervention in the weather would have a "sequela" to the overall climate. For such a question, Sun Jisong said that in the face of nature, the intervention that human beings can do is extremely small and it is impossible to have an impact on long-term climate change. "In fact, every time it rains, we basically carry out precipitation enhancement operations." Sun Jisong said that due to the long-term drought in the northern region, basically every precipitation process throughout the year, the relevant departments will carry out precipitation enhancement operations, and the snowfall process is no exception. If there is snow, artificial "snow increase" measures will be taken. According to media reports, from February 1 ST to February 2 nd, the weather modification department of Luoyang City, Henan Province seized the opportunity of weak cold air crossing the border and successfully implemented artificial precipitation enhancement. "But only when there is water in the sky can we make it fall to the ground as much as possible."


    Guess 3


  Is the Three Gorges Project the Source of Extreme Weather?


    In recent years, the term "extreme weather" has appeared more and more in public, and the coincidence of these extreme weather occurrences and the completion time of the Three Gorges Dam also makes many people suspect that the Three Gorges Dam is the source of extreme weather.


    "The problem of the Three Gorges is a cliche, but from a scientific point of view, the statement that the Three Gorges caused extreme weather is unfounded." Climate change often involves thousands of kilometers in Fiona Fang. Compared with this climate background, Sun Jisong described the Three Gorges as a small "puddle", and it is difficult to have any impact on the overall climate if there is such a puddle.


    "At present, most climatologists believe that global warming will cause an increase in extreme weather." With global warming, the frequency of extreme weather is increasing, but how global warming affects the appearance of extreme weather and what is the inevitable relationship between them is still an unsolved mystery.


    Guess 4


  Beijing this summer


  Will there be a drought?


    Is there a scientific truth behind the poetic folk proverbs, such as "Yun Zheyue on August 15th, the lights on the fifteenth day of the first month when it snows" and "It doesn’t snow when it’s cold, and the fields crack when it’s summer"?


    "Folk proverbs are more similar to statistical induction, and some of them have some truth," Sun Jisong said. The predictions in folk proverbs are not necessarily correct, and winter drought does not mean that summer drought will continue. "The weather on a certain day is not necessarily related to the weather on a certain day in a few months."


    "However, the lack of snowfall will increase the possibility of pests and diseases, which will have a negative impact on the growth of overwintering crops. From this perspective, it will indeed have a certain impact on agriculture if it does not snow in winter." Snow-free winter not only has less flavor, but also lack of snow can cause many problems. In an interview with the media, Pan Jiahua, director of the Urban Development and Environment Research Center of China Academy of Social Sciences, said that precipitation will make the living environment worse and seriously restrict social production. "Although warming in winter can shorten the heating time and reduce related expenses, its disadvantages still outweigh its advantages."


  Investigation reminder


  Watch out for colds when it’s dry and snowy.


    During the Spring Festival, Dr. He, who works in a community hospital, was busy. Due to the dry air, the number of patients with sudden respiratory diseases suddenly increased during the Spring Festival. Every day, the hospital received dozens of patients who had infusion bottles, and the top three hospitals were crowded. Experts said that due to the low air humidity, some viruses are easy to reproduce and easily lead to a series of diseases. During the Spring Festival in Beijing Children’s Hospital, an average of nearly 5000 children came to see a doctor every day. On the first normal outpatient day after the festival, more than 4,000 outpatient visits were made in the morning alone. Among them, children with respiratory tract infection are the most.


    "It doesn’t snow, which is very bad for human health." Doctors at Chaoyang Hospital in Beijing said that because of the dry air, people are prone to chapped lips, bleeding nostrils and itchy throat. When the air humidity is lower than 40%, the respiratory mucosa of the nose and lungs will be dehydrated and the elasticity will be reduced, making dust, bacteria, etc. easily attached to the mucosa, stimulating the throat and causing cough.


    However, the spread of cold will be accelerated because of the accelerated reproduction of influenza virus in dry environment and its survival on floating dust. However, due to the failure of "wet deposition", urban air pollution will be serious and respiratory diseases such as asthma and pneumonia will be easily caused.


    "The way to prevent diseases is a cliche, but many people always pay no attention." Experts say that opening windows regularly to ventilate and maintain indoor humidity will help prevent diseases. At the same time, we should try to avoid going to crowded areas. People with respiratory diseases should wear masks when going out.
