CCTV News:With the arrival of summer, strong convective weather is frequent, and lightning disasters also need attention. So how is the lightning disaster produced and how to prevent it? Let’s get to know the relevant knowledge through a set of hand-drawn animations.

Lightning is an ultra-long distance discharge process in the atmosphere. Lightning has powerful current, scorching high temperature, strong electromagnetic radiation and violent shock wave, which makes it instantly become a "wreck-it ralph", causing lightning disasters. Cloud — Lightning, that is, when there is a discharge between the cloud and the earth, will have a great impact on human activities. Lightning strike can also change into a pattern, and it can be attacked by direct lightning strike, contact voltage, side lightning strike and step voltage. Lightning electromagnetic radiation may also interfere with and destroy the computer system and its data storage.

How do I know how far this dangerous lightning is from me?

Lightning and thunder were born at the same time, but they didn’t run as fast. Light can travel about 300,000 kilometers per second, while sound can only travel about 340 meters per second. Therefore, if you see lightning and hear thunder every 10 seconds, this thunderstorm is about three or four kilometers away.

If you are not sure of the time, you can also listen to the sound to feel it. When the lightning is close, it hears a sharp crack, and when it is far away, it is a rumbling sound. Generally speaking, if thunder can be heard, it will be within 10 kilometers. When encountering lightning weather, it is best not to use the solar water heater on the roof again, because water can conduct electricity and there is a hidden danger of lightning strike.

If you can’t find a suitable and safe lightning protection place outdoors for a while, you can try to squat down, bow your head, put your feet together and tuck your knees in your hands to avoid the "step voltage" damage caused by lightning. Because, when lightning is released from the cloud to the earth, it will produce a potential field, and the closer it is to the lightning point on the ground, the higher the potential is. If the site potentials of the two feet are different when lightning strikes, this potential difference will generate a voltage between the two feet and a current will pass through. The greater the distance between the feet, the greater the step voltage.

As the saying goes: it is not advisable to get off the bus to avoid the rain, and the car entertainment should be closed; All the windows should be closed tightly, and it can’t ride a bicycle or motorcycle; Don’t walk too high with an umbrella, and remove all metal ornaments; If lightning and thunder are similar, squat down and tuck your head to avoid.

　　Time: May 10th.

　　Agenda: General Secretary of the Supreme Leader inspected and presided over a symposium on promoting the construction of xiong’an new area with high standards and high quality in xiong’an new area, Hebei Province.

　　As xiong’an new area is near, there are more construction sites and more new buildings. Through the window, General Secretary of the Supreme Leader stared at this miraculous new city.

　　This is the third time that the General Secretary has visited Xiong ‘an in six years, and the transportation has changed. It’s my first time here, or by car. That was in February 2017, General Secretary of the Supreme Leader set off from Zhongnanhai, more than 100 kilometers south, and went to a farmland in Anxin County, Hebei Province for on-the-spot inspection. Going again this time, Fuxing has been flying fast for more than 50 minutes, and Xiong’ an has been integrated into the "one-hour traffic circle of the capital".

　　Xiong ‘an’s appearance has changed. In the past, she was a regional short board under the "siphon effect" of Beijing and Tianjin. Next to Baiyangdian Lake, planted with crops, ancestors never thought that they would usher in a once-in-a-lifetime historical opportunity in the new era and become a hot spot for the coordinated development of Beijing-Tianjin-Hebei and a benchmark for high-quality development.

　　It has been brewing for a long time and has been waiting for a long time. Anxin, Xiongxian and Rongcheng are surrounded by Baiyangdian, the "Pearl of North China". The new name of this land, Xiong ‘an, was announced to the world in April the year after the first investigation by the General Secretary. Since then, "Millennium Plan, State Affairs" has been written in history.

　　On the coast of Bohai Sea, on the bank of Taihang Mountain and at the foot of Yanshan Mountain, it is consistent that "the Party Central Committee always gives the greatest hope" in investigation, decision-making, planning, construction, ground breaking and jointing. In the past six years, we have not only witnessed the emergence of the "city of the future" in the new era, but also witnessed the sound of the concept of urban planning and construction advocated by the General Secretary of the Supreme Leader.

　　 　"Bull’s nose" and "spreading pie" are strategic choices.

　　Tracing back to the birth of xiong’an new area, we should start with the capital Beijing.

　　Being too big is one of the "growing pains" in Beijing. When the "ceiling" of "spreading the pie" construction is within reach, pressure and pain points follow. As early as 2014, when investigating in Beijing, the General Secretary of the Supreme Leader compared the image of urban construction and development as "you can’t step on watermelon skin and slide wherever you go". "There should be a top-level design and control, and the limit should be set, beyond which you can’t grow any more".

　　Looking inward, it is difficult to solve the problem; Looking outside, my thoughts suddenly became clear. The general secretary put forward the coordinated development strategy of Beijing-Tianjin-Hebei to relieve the function of Beijing’s non-capital, which was full of vitality.

　　Whether it is "seeking a territory from the overall situation" or "blocking it is better than sparse", the Chinese civilization with a long history has a new vitality in the new era. The general secretary described "relieving the function of Beijing’s non-capital" as "moving a surgical operation" and "breaking the mindset of circling on one acre and three points".

　　Another problem has followed, and it is relieved outward. Where is the bearing place? Not too far, not too close, many factors are weighed and compared, so xiong’an new area came into being.

　　The bearing place is the reason for the birth of the new district and the initial heart of the Millennium plan and national affairs. "To link up with Beijing’s non-capital function transfer, we must keep this initial intention in mind." The general secretary told me.

　　The country is big and the party is big. On the land of more than 9.6 million square kilometers, the decision-making and deployment of the CPC Central Committee is like an armband. In Beijing, Tianjin and Hebei, with a population of more than 100 million and a land area of 216,000 square kilometers, it is a common responsibility and a common future to nurture a new area with unlimited possibilities.

　　Spread the map, Beijing-Tianjin-Hebei "different petals, but concentric petals." A picture, a chess game, a strong momentum, the power is cooperating, and the future is also cooperating.

　　From a collaborative perspective, go to see the general secretary’s investigation in Xiong’ an. At the construction site of Xiong ‘an Intercity Station and International Trade Center Project, he watched the sand table and boarded the platform. On the construction site in full swing, the headquarters of central enterprises in Beijing and the second-and third-tier subsidiaries are being built.

　　"World vision, international standards, China characteristics, high-point positioning" is a modern new city, but also a new road to the future, branded with the essential features of Chinese modernization.

　　When the general secretary talked about Xiong’ an at the Standing Committee of the Political Bureau of the Communist Party of China Central Committee meeting in February 2018, he described the imprint of a city:

　　"The establishment of the Shenzhen Special Economic Zone in the early days of reform and opening up has created the speed of Shenzhen. Today, 40 years later, we set up xiong’an new area to aim at 2035 and the middle of this century ‘ Two steps ’ The goal of creating ‘ Xiong ‘an Quality ’ It has become a national model in promoting high-quality development. "

　　 　"Fast" and "Slow" are the visions in a blueprint.

　　A thousand-year plan is an extraordinary pen.

　　The second time I went to Xiong’ an was in January 2019. General Secretary of Supreme Leader made an in-depth investigation of xiong’an new area Planning Exhibition Center.

　　This fertile ground for sowing hope, after the thunder two years ago, has been brewing the power that affects the future: planning.

　　Lay the chessboard first, then move it. "I have said many times that planning is the first thing to look at when investigating a city. Planning science is the biggest benefit, planning mistakes are the biggest waste, and planning toss is the biggest taboo."

　　At the beginning of the establishment of the new district, facing the urgent expectation of the outside world for a new city from the flat, where to go? Behind the choice is foresight and determination. General Secretary of the Supreme Leader solemnly warned: "xiong’an new area will be our historical legacy for future generations" and "Plan every inch of land clearly before starting construction, and don’t leave historical regrets".

　　In two years, the plan has been polished repeatedly, and how many times it has been placed on the desk of Zhongnanhai. One foot, one inch, one stroke, one painting, the male who sinks down slowly and steadily.

　　"In the past two years, almost no bricks and tiles have been moved. Now that there is a blueprint, Xiong’ an has shifted from the top-level design stage to the substantive construction stage, and this year may be a hot situation. " The General Secretary’s second trip to Xiong ‘an clearly marked the development rhythm of Xiong ‘an.

　　Fast or slow? In a strategic vision more than 30 years ago, we can see the general secretary’s consistent concept of urban work. Today, we are standing at the source of creating the future. At that time, the supreme leader comrade wrote in the preface of "Fuzhou’s 20-year economic and social development strategy".

　　Time has recorded the rapid development under slow planning. In 2021, when he visited Fuzhou, the general secretary said with emotion: "The current construction is in line with this direction, consistent with our vision at that time, and it has developed better than our vision."

　　"I have never seen such a plan for a city." "I have never seen the above ground, underground, ‘ Cloud ’ On ‘ Tri-cities ’ Integrated planning and construction "… … Slow and steady, and seize the day. Xiong’an new area has taken a development path that no one has taken in human history, and expanded the development space of Chinese modernization.

　　Chinese modernization is a modernization with a huge population. When hundreds of millions of people flood into cities and towns, the concept of intensive land use is bound to run through the planning and design. This survey looked at the construction of Xiong ‘an Intercity Station, and the General Secretary of the Supreme Leader mentioned the traffic problem, which is one of the "big city diseases": "We should work hard to build a three-dimensional comprehensive transportation network, make full use of underground space, and strive to build a city without ‘ Urban disease ’ The city of the future. "

　　From the report of the 19th National Congress of the Communist Party of China, which emphasized "planning from a high starting point and building xiong’an new area with high standards" to "building xiong’an new area with high standards and high quality", Report to the 20th CPC National Congress, who joined the Party, went through the time sequence and drew a blueprint to the end.

　　During this trip, General Secretary of the Supreme Leader continued to emphasize that the high-standard urban planning blueprint should be truly turned into a high-quality realistic picture of urban development.

　　 　"Water" and "City" are harmonious symbiosis in a picture.

　　The general secretary is concerned about Baiyangdian.

　　The first time he went to Xiong ‘an, he went to see Baiyangdian. At the bottom of the nine rivers, water and rhyme are in harmony. The Supreme Leader General Secretary said: "When I was a child, I read the story of Zhang Ga, a soldier, and I was very fascinated here." The second time, the general secretary asked about the recent situation of Baiyangdian in the planning and exhibition center, and he was very concerned.

　　This time, before presiding over the symposium on promoting xiong’an new area’s construction with high standards and high quality, the General Secretary took the time to watch a short video of Baiyangdian. The progress of dredging and connecting hundreds of lakes is in my heart.

　　Water and city, a necessary question for urban development.

　　"At that time, the site was chosen here to protect Baiyangdian, not to damage Baiyangdian. The city and the lake should reflect each other and complement each other. " Setting the city by water, the land by water, the people by water, and the production by water are important dimensions for the development of the Supreme Leader General Secretary.

　　Opening the map of China, the lack of abundant resources in the north and abundant resources in the south is one of the characteristics of water resources distribution in China.

　　The problem of water shortage was felt when I was young. In February 2014, when listening to the report on the coordinated development of Beijing-Tianjin-Hebei, the Supreme Leader General Secretary solemnly warned: "The water shortage problem in North China is already very serious. If we don’t pay attention to protecting the ecological spaces such as forests, lakes and wetlands that conserve water, and continue to overexploit groundwater, the intensity of natural retaliation will be even greater."

　　Water resources, the hard constraint of development.

　　At the beginning of the planning and construction of Xiong ‘an, the General Secretary of the Supreme Leader repeatedly stressed the need to save water and conserve water sources: "The abundant water resources here are good for building the city, but in retrospect, you should not destroy our water source and our ecological wetland. Pay attention to this aspect because of the city. "

　　The relationship between "water" and "city" is a mirror of the relationship between man and nature.

　　Mountains and rivers, forests, fields, lakes, grass and sand, the elements of natural ecology, determine the resource endowment and location conditions of a place, and determine the regional development space and resource and environmental carrying capacity. "How much soup there is?" General Secretary of the Supreme Leader used this simple sentence to explain that planning and development should be based on reality and adapt to local conditions.

　　Xiulin, Green Valley and Dianwan form the ecological space skeleton of xiong’an new area’s starting area. Looking at the "forest", when I went to Xiong ‘an for the second time, the Supreme Leader General Secretary drove through the "Millennium Xiulin" to see the growth of trees. Nowadays, young trees are flourishing. Planting trees before building cities has become a new concept in the construction of new districts.

　　Look at the "city", look up and travel, and the proportion of green transportation in the starting area of the new district accounts for 90%; Building a building, clear green building standards, how much construction waste to reduce and how much energy to save have all become the key to decision-making.

　　At this symposium, General Secretary of the Supreme Leader once again stressed that xiong’an new area should adhere to green and low-carbon development and build itself into a model city with green development.

　　 "New" and "Old" are the pulse inheritance of one article.

　　Mountains and rivers surround the city, and culture builds the city. The "City of the Future" and the Millennium context complement each other. "Culture is the soul of a city."

　　Protection and development, transformation and new construction, tradition and modernity are faced by Xiong ‘an in the construction, and thousands of cities are also experiencing it. Behind the priorities, it is also answering the question of "what road to take" in the largest urbanization process in human history.

　　Old trees don’t move, ancient buildings don’t tear down, and ancient archways don’t move … … In 2018, xiong’an new area launched the special action plan of "Remembering Homesickness".

　　"The city is a science. It has meridians, pulse and texture like the human body. If you don’t treat it scientifically, it will get sick." General Secretary of the Supreme Leader once quoted this sentence by architect Liang Sicheng. History and culture are also the meridian texture of the city.

　　Open the Planning Outline of xiong’an new area, Hebei Province, and "historical and cultural protection" is a separate section. General Secretary of the Supreme Leader clearly pointed out that the construction of xiong’an new area should "persist in protecting and carrying forward the excellent Chinese traditional culture and continue the historical context".

　　"Only by persisting in moving from history to the future and forging ahead from the continuation of national culture, can we do a good job in today’s cause." The wave of urbanization is surging forward, and the balance between "new" and "old" is crucial to the future.

　　The "old" that I care for is the history and civilization that has been passed down for thousands of years;

　　The "new" of positive development is a new format, new model, new growth point and new kinetic energy under the tide of the times.

　　At the symposium on this trip, the General Secretary of the Supreme Leader mentioned the word "new" many times: "We must fully implement the innovation-driven development strategy, promote the frontier policies and measures of reform and opening up in various fields and forward-looking innovation pilot demonstration projects in Xiong’ an, and strive to build new functions, form a new image, develop new industries, gather new talents, and build new mechanisms to make xiong’an new area an innovative highland and a hot spot for entrepreneurship in the new era."

　　In Xiong ‘an people’s eyes, the past urban development model was industrialization driving urbanization, while Xiong ‘an was urbanization driving industrialization and informatization.

　　During this inspection, General Secretary of the Supreme Leader arrived in Xiong ‘an, got off the high-speed train and first looked at Xiong ‘an Station and its Zangang area. The "urban blank space" in front of us has unlimited potential. The general secretary said: "The Zangang area should be built into a high-end high-tech industrial cluster, so that visitors from all walks of life can feel the new modern atmosphere of xiong’an new area as soon as they arrive in Xiong ‘an".

　　The new atmosphere of modernization, where is "new"?

　　China has entered a new stage of development. The new development concept is integrated into the blood and bones of Xiong’ an construction.

　　"First of all, the new district should be forward-looking and leading in the concept of planning and construction." Smart, green and innovative, these bright business cards tell the new story after the new development concept "settled in Xiong’ an".

　　History and future meet here.

　　"Jiangshan has been a good guest since ancient times. Who is the Taihang for misty rain?" This eternal question on the tower of Guxiong Prefecture has passed through long years.

　　 "Seeing things" and "seeing people" are the initial intentions of people’s cities.

　　"City, so Shengmin also." A city has not only reinforced concrete, but also wind and rain, flowers and birds singing, and homes to live in.

　　This time in Xiong ‘an, General Secretary of the Supreme Leader went to Rongdong District, the first centralized built-up area in the new district: "I have been worried about the relocated people, and I am very pleased to see that everyone has a good life. To build a good xiong’an new area, it is important to link up living and working in peace and contentment, so that the people can live steadily, live safely and have a head start. "

　　The city of the future is the city of the people.

　　Xiong’ an has builders, relocated people, entrepreneurs, and "aborigines" who have turned farmers into citizens. As the sun rises and sets, they grow up with Xiong ‘an. The general secretary clearly pointed out: "We are not building a beautiful new city, but just building a new city for the people to live a better life."

　　"Serving the people wholeheartedly and providing fine urban management and good public services for the people are the focus of urban work, and we can’t see things but people." In December 2015, at the Central City Work Conference, the General Secretary of the Supreme Leader deeply thought about the initial heart of the city.

　　"The concept of making people’s lives more comfortable is integrated into the blood of urban planning and construction and reflected in every detail."

　　Governing the city, under the "embroidery" effort.

　　"It is necessary to promptly perceive the worries, worries and worries of community residents and solve them one by one". "Vegetable basket", "rice bag" and "fruit plate", when working in the local area, the General Secretary of the Supreme Leader put these "small things" of people’s livelihood on his desk as major events.

　　The essence of modernization is human modernization.

　　For the people, rely on the people and benefit the people. The "Xiong ‘an Scene" of Chinese modernization takes the people as the center and explores a new path to build a modern city with new development concepts. Foreign media commented that Xiong ‘an is a tangible and vivid model of Chinese modernization.

　　For thousands of years, China, a rural area, is experiencing the most magnificent changes of human society in the 21st century in the eyes of western scholars, as well as the largest and fastest urbanization process in the world history since the reform and opening up.

　　New cities, new explorations and new roads are full of thank you sir, with historical patience and infinite vitality.

　　In just 6 years, I went to Xiong’ an three times. Millennium plans and national events are often in the deep concern of the Supreme Leader’s General Secretary.

　　In just six years, xiong’an new area has gone from scratch, from blueprint to real scene, a future city without "urban diseases", a "people’s city" suitable for business and living in a new era, and a high-level and modern city is springing up.

　　This is another miracle written on the land of China in the new era.

On April 18th, Chery started the pre-sale, and the new car launched a total of four configuration models, with the pre-sale price range of 159,900 to 199,900 yuan. Fengyun T9 positioned a compact SUV equipped with Chery C-DM hybrid system.

At the pre-sale conference, the official said that 9.9 yuan can participate in crowdfunding or lottery if it orders. When the total order volume is less than 10,000, the listing price will be reduced by 5,000 yuan, and so on, the highest price will be reduced by 20,000 yuan.

Fengyun series is a brand-new energy sequence of Chery brand, which was officially released in November last year. At the same time, it will adopt a brand-new product Logo, and it will launch 11 brand-new models in the next two years, based on Chery Kunpeng’s super C-DM hybrid technology.

Under Chery’s new energy brand system, there are currently four new energy brands: Chery New Energy, Jietu, Xingtu and iCAR, and the Fengyun sequence in Chery New Energy has been restarted into a hybrid brand, and Xingtu’s Star Era is defined as the high-end brand of Chery New Energy.

Fengyun T9 Appearance & Interior Appreciation

As Chery’s brand-new energy sequence, we feel a strong "new energy smell" from its front face design. The front face of the new car adopts a large-area closed grille, but the traditional grille position still adds matte silver trim strips to outline the shape, which is very aura as a whole, while the air inlet for the engine is hidden under the front face.

Coming to the side of the car body, Fengyun T9 uses privacy glass in the back row, and there are not too many complicated lines in the whole car body. The shape of the traditional SUV benefits from the size and also shows its gas field.

The detailed design part, now hidden door handles, large-size wheels and so on have been given.

In terms of body size, the length, width and height of the new car are 4820X1930X1710mm and the wheelbase is 2820 mm.

The shape of the tail echoes the front face, adopting the design of penetrating taillights, with Chery’s LOGO in the center, and the whole tail seems to have a wide horizontal vision.

In terms of interior, Fengyun T9′ s style is also consistent with the current mainstream. In the center console of the car, there is a large-size floating screen with an estimated size of 15.6 inches, and it is expected to be equipped with Qualcomm Snapdragon 8155 chip, which will bring high vehicle performance and look forward to the subsequent static performance experience.

The main driving instrument also uses a separate floating screen with an estimated size of 10.25 inches.

Other features include zero-gravity seats, wireless charging function of large wattage mobile phones, ventilation, massage and heating of front and rear seats, and other comfort configurations.

In terms of power, Fengyun T9 this time is a hybrid model, with Kunpeng power, 1.5T engine, 3DHT gearbox and CDC suspension system. There will be two versions of two-wheel drive and four-wheel drive. The maximum power of the two-wheel drive motor is 165kW, and that of the four-wheel drive motor is 340kW.

In terms of battery life, the two-wheel drive CLTC has a pure battery life of 160km, and the four-wheel drive version is 150km；; The comprehensive mileage of two-wheel drive and four-wheel drive is 1320km/1100km, respectively, and the power loss and fuel consumption are 5.7L/100km.

C-DM hybrid system

At present, Chery is fully turning to new energy sources, and the hybrid field relies on the Kunpeng super-performance electric hybrid-C-DM independently developed by Chery, equipped with the fifth-generation ACTECO 1.5TGDI high-efficiency hybrid special engine and the third-speed super-electric hybrid DHT.

Under this platform, it can cover a variety of vehicles and power combinations, including A-B cars, SUVs and MPVs, 5-seat, 6-seat and 7-seat vehicles. In terms of power, it covers 1.5T, 2.0T and 1.5L hybrid special engines, as well as 13DHT and 3 DTH hybrid boxes with different power and torque.

Among them, the fifth-generation hybrid engine is the latest achievement of Chery in the hybrid field, and it has the technical applications of Miller Cycle technology, 4.0i-HEC fourth-generation intelligent combustion system, HTC high-efficiency supercharger, i-LS intelligent lubrication system, i-HTM intelligent thermal management system, HiDS high dilution system and so on.

The power system can achieve the maximum effective thermal efficiency of 44.5%, fuel consumption of 4.2L per 100 kilometers and maximum power of 115kW.

In the aspect of hybrid DHT gearbox, three-speed super electric hybrid DHT and stepless super hybrid DHT are also built. Among them, the three-speed super electric hybrid DHT is based on dual-motor drive and three-speed DHT, which has the characteristics of the highest transmission efficiency of 97.6%, acceleration of 4.26s per 100 kilometers, and torque distribution before and after 0-100%.

The stepless super hybrid DHT also realizes the driving state of non-inductive variable speed through E-CVT, and also has the characteristics of pure electro-acoustic pressure level and average efficiency of 90%.

Long battery life is still popular.

The recently announced new energy penetration rate seems to have exceeded 50%, among which the sales of plug-in and extended-range vehicles with large batteries have performed well. From the perspective of car scenes, most car scenes in the city can use pure electricity and long-distance car oil without worrying about energy replenishment, which has become the mainstream car choice for domestic users.

Nowadays, the pure electric life of the vehicle is basically the same as the extended range, and there is no difference in experience. Therefore, the demand for such vehicles is still strong and will gradually replace the pure fuel vehicles. Just like Chery, it will launch 11 new plug-in models in the next two years, which shows that it has been accumulating power for a long time.

Near the college entrance examination, how to fill in the volunteers must be a tangled problem for many students. Today, we share with two professors, one is Professor A from Peking University, who returned to the United States, and the other is Professor B from the Third Hospital of Beijing Medical University, who is trained in China, their personal feelings of many years of medical professional study and research, so as to open the thinking space for students to fill in their volunteers.

Question 1: There are many medical disciplines. If you help your child to fill in the volunteers, what major do you want to choose?

Professor A: Depending on the child’s talent, it is recommended to study basic medicine or clinical medicine. General talent, studying clinical medicine; If the talent is very general, it is best not to study medicine.

Professor B: I will choose clinical medicine.

Judging from the number of disciplines and specialties in China, medicine ranks third except engineering and science. Its first-level disciplines include basic medicine, clinical medicine, stomatology, public health and preventive science, traditional Chinese medicine, integrated traditional Chinese and western medicine, pharmacy, special medicine, medical technology and nursing, and there are several specialties under it. To fill in the volunteer professional choice, candidates should not only look at their own interests, but also their own abilities.

Question 2: Would you choose Chinese medicine or western medicine for your child?

Professor A: Western medicine is good, but Chinese medicine is not excluded.

Professor b: western medicine.

It’s very interesting. The two of you basically agree and are very concise. Here, candidates are reminded that when they choose Chinese medicine or western medicine, they still need to make a decision according to their own situation and hobbies.

Question 3: What do you think of studying medicine for employment?

Professor A: In the long run, the medical profession will not be unemployed.

Professor B: At present, there is a dilemma in the employment of medical majors, that is, large hospitals are difficult to find jobs and small hospitals are unwilling to go. Generally speaking, the employment prospects of medical majors are not very optimistic.

Your views are somewhat different. It is difficult to study medicine and obtain employment, which is largely subject to the problem of system construction. As long as you put yourself in the right position, as a doctor, you won’t worry about your basic life and development. Last month, we went to Hiroshima, Japan for academic exchange, and found that there was a specialized hospital with only a few rooms every 200 meters on the street, which was popularly called a community hospital. Patients go to big hospitals only when they are seriously ill, while ordinary diseases go directly to community hospitals. If a large number of community hospitals are set up in China, it will not only solve the contradiction between doctors and patients, but also make full employment for medical students, and effectively use hospital resources and reduce medical expenses.

Question 4: Do you need to have good basic knowledge of science such as mathematics to study medicine?

Professor A: Yes. Medicine is a comprehensive subject based on mathematics, physics, chemistry and biology.

Professor B: You don’t have to.

Whether you need basic knowledge of science, such as mathematics, depends on which major you choose in the medical discipline. Therefore, candidates must know something about the courses of the selected major when filling in their volunteers.

Question 5: Do you have any suggestions for students who choose to study medicine?

Professor A: Good moral quality, good health and good brain.

Professor B: To be a doctor, not a doctor, you should pay attention to studying medical history.

Studying medicine is not only to learn medical technology, but also to have love and awe of the profession, otherwise it is impossible to become a good doctor.

Summary: As for the candidates’ volunteering, first, they should be considered comprehensively in combination with their own interests and college entrance examination scores. When choosing a volunteer, you should put your interests and hobbies in the first place. However, due to the limitation of scores, the medical school reported in the college entrance examination may not be ideal, but in the future, you can "save the country by curve" and go to your ideal university. Second, you must not be eager for quick success and instant benefit when filling in your volunteers. Employment and income must be considered when filling in volunteers, but they cannot be put in the first place. The development of the industry may be "thirty years in the east and thirty years in the west". It should not be the choice of ambitious people to fill in the college entrance examination volunteers only considering the immediate interests.

The Island conference

1905 movie network news　On the afternoon of August 8th, director Bo Huang’s works held a premiere conference in Beijing. Due to the weather, the founders made a forced landing in Jinan. Fortunately, the weather was beautiful. Although the press conference was postponed, all the staff were present. At the press conference, Bo Huang, Wang Baoqiang, Shu Qi, LAY, Yu Hewei, Wang Xun and others appeared in succession. After watching the documentary film, Shu Qi even shed tears on the spot, saying that his tears were for Bo Huang and the staff.

　The founders jumped rope together.

The press conference of the day played the concept of "group building". In addition to chatting about their roles, the masters also played the game of jumping long rope in the movie. Shu Qi and Bo Huang shook the rope, and Wang Baoqiang jumped several times in a row, followed by Yu Hewei and Wang Xun. After Bo Huang counted "very satisfied", LAY joined the rope skipping team again, but only jumped one time and then broke off.

　Bo Huang shed tears

But after watching a behind-the-scenes tidbit, many masters became red-eyed. Wang Xun, Yu Hewei and Shu Qi also shed tears at the scene. Shu Qi said that his tears were for Bo Huang and the staff. Later, he said that when everyone was working hard outside, they were eating desserts in the hotel. Bo Huang took the words to comfort Shu Qi and said, "The arrangements for the scenes are different."

　Bo Huang, Shu Qi

Shu Qi wept.

Because I spent two and a half months in continuous shooting on the island, all the founders also said that the scenery was beautiful but very boring. Wang Baoqiang, Wang Xun and Yu Hewei revealed that the only entertainment on the island is going to the supermarket, only looking at it every day without buying it. Later, it was found that there were many hot springs after the low tide, and the three went to the hot springs after the filming, and they "frankly met" every day. As a result, Bo Huang immediately ridiculed: "When the sun sets, can the scenery be good for three such men?"

　LAY

Bo Huang acted as a director for the first time, and LAY, who has worked with him many times, said that Bo Huang and The Island’s director Bo Huang were totally different in Extreme Challenge, and felt that directing Bo Huang was even harder. He also thanked the director Bo Huang for his appreciation on the stage.

　

At the end of the conference, the letters written by the founders to Bo Huang were also made public for the first time through video. Previously, the road performance activities led by Bo Huang, the leading film actor, were also shown through video. The film The Island will be officially released on August 10th.

▲ The 1.5T engine with a maximum output of 125kW has a general power performance for Kusitu, but fortunately, this 7-seat MPV power for home use is not the main appeal of users.

▲ Kustu is very easy to drive. No matter on the expressway or on the congested urban roads, I don’t feel that I am driving a 7-seat MPV with a length of nearly 5 meters and a wheelbase of 3055 mm. This is a handy car to drive!

▲ As a top model, too much hard plastic is used in the interior panel.

▲ The third row has air conditioning outlets and cup holders, and the seating space is also good, but the overall material and technology need to be improved.

▲ Sonata is not sold well, and the fundamental reason is that the product competitiveness of the ninth generation Sonata itself is insufficient.

▲ In the first half of 2021, the Accord’s hybrid models accounted for 15%, but the Odyssey has long been all hybrid models, and it is very popular in the market. It is an obvious fact that,The relative advantages of HEV and PHEV are more prominent in high-end MPV models, and are more easily accepted by users.

▲ Kustu is very good, and it would be more perfect if a mixed version could be produced!

　　CCTV News:Samsung designed the face brushing function to cancel the cumbersome switch button; Apple applied the face-brushing function to replace the complicated power-on password; The airport uses the face brushing function to facilitate passengers to board the plane more quickly.

　　It is not an exaggeration to say that we have entered an era of "brushing our faces".

　　In this era, our faces are often exposed to various accurate cameras. Who are you? Where are you? What are you doing? These have become recorded data and accessible information.

　　这到底是不是一件好事呢？

　　如今，学生们还在尝试将监控技术提升至更高级别，把模糊的面部图像变清晰，把平面图像变成3D图像。不仅如此，升级后的技术还可以仅利用人脸的局部特征，如眉毛、眼睛或嘴，通过在数据库中搜索有相似特征的人，确定一个人的身份。

　　现实之中，人脸识别技术的运用已越来越广泛，最受关注的是被政府和执法部门使用。

　　2018年6月5日，美国政府宣布要进行一项测试：花两个月时间，在佛罗里达州和得克萨斯州收集大量居民日常活动的画面，形成数据库，然后从今年8月开始，利用面部识别技术监控和辨认出入美国和墨西哥边境的人口和车辆。

　　这一项目的启动，立刻引发舆论哗然，反对者称这是对公民隐私权的公然侵犯。
