The professional examinations organized by the enrollment institutions themselves are arranged by the enrollment institutions themselves.

　　19. What is the difference between high-level sports teams and sports?

　　A: The subjects of high-level sports teams are general, and they study in general majors after being admitted to colleges and universities. It is for ordinary colleges and universities to recruit candidates with sports expertise in order to enliven the campus sports atmosphere and meet the team-building needs of university sports meetings. Sports candidates apply for sports, and after being admitted to colleges and universities, they study sports majors such as physical education and social sports.

　　In terms of examination, according to the regulations of the Ministry of Education, the professional examination of high-level sports teams is organized by combining national unified examination, college entrance examination and college examination, and the examination implementation plan is formulated by the Science and Education Department of the State Sports General Administration. Sports candidates must take the provincial unified examination for sports majors.

　　20. Are the scores of compulsory subjects in the ordinary high school level test valid in the 2021 college entrance examination?

　　A: According to the "08 College Entrance Examination Scheme" of Jiangsu Province, the scores of compulsory subjects in the academic proficiency test of ordinary high schools are counted from the year of the college entrance examination and are valid for three years.

　　Candidates’ achievements in the compulsory subjects of the academic proficiency test from 2018 to 2020 are regarded as the academic proficiency qualification test results of the corresponding subjects, that is, if the candidates obtain "A, B, C" or "Qualified" in the compulsory subjects of the academic proficiency test in 2018 and beyond, they are regarded as qualified in the academic proficiency qualification test; If the score of the required course of learning and testing is "D" or "unqualified", it will be deemed that the subject is unqualified in the academic level qualification examination.

Out of the ICU, but not ashore yet. This is the evaluation of Xpeng Motors’s 2023 financial report by many people in the industry.

On March 19th, the latest data disclosed by Xpeng Motors showed that in 2023, the company’s total revenue was 30.68 billion yuan, a year-on-year increase of 14.2%. In terms of delivery volume, Xpeng Motors delivered 141,600 new cars in 2023, a year-on-year increase of 17%.

Although both revenue and delivery have increased, Xpeng Motors has not yet got rid of losses. In 2023, the net loss of Xpeng Motors was 10.38 billion yuan, which was 13.6% larger than that of 2022 (loss of 9.14 billion yuan). The gross profit margin of automobiles for the whole year was -1.6%.

The adjustment was effective, but it did not get rid of the annual loss.

Throughout the whole year of 2023, Xpeng Motors’s financial performance improved in the fourth quarter of that year, but it was under pressure due to the performance in the first three quarters.

The financial report shows that in the fourth quarter of 2023, the gross profit margin of automobiles in Xpeng Motors was 4.1%, while in the third quarter it was -6.1%, and the gross profit margin turned from negative to positive. In 2023, the gross profit rate of automobiles in Xpeng Motors was -1.6%, and in 2022 it was 9.4%.

It is reported that although Xpeng Motors has adopted discount and preferential policies for its models in order to meet the year-end sales, the change of sales structure and the change of average bicycle price have made Xpeng Motors improve its gross profit margin. In terms of sales structure, the proportion of Tucki G9 with higher unit price increased from 7% in the third quarter of 2023 to 26% in the fourth quarter.

In terms of bicycle cost, in the fourth quarter of 2023, the bicycle cost in Xpeng Motors was 191,000 yuan (excluding the impact of deduction), a decrease of 11,000 yuan from the previous month. The reason is that although the price of the new Tucki G9 is lower than that of the old one, the gross profit margin exceeds that of the old one under the technical cost reduction. At the same time, the price of lithium carbonate continued to decline, which naturally reduced the cost of vehicles in Xpeng Motors.

In fact, the above data changes are the result of Xpeng Motors’s continuous adjustment for more than a year. Since October, 2022, Xpeng Motors has made adjustments in its organizational structure. Especially after Wang Fengying joined Xpeng Motors as president, he tried to achieve the goal of cost reduction by streamlining SKUs, eliminating inefficient stores, merging sales theaters and optimizing purchasing strategies.

According to the financial report data, "saving money" has become one of the key directions of Xpeng Motors in 2023. This year, the number of employees in Xpeng Motors decreased from 15,829 in the same period last year to 13,550. At the same time, in terms of R&D, Xpeng Motors only increased its expenditure by 1.2% in 2023, and the number of R&D personnel decreased from 6,313 in the same period last year to 5,401.

Thanks to various measures, although the situation in Xpeng Motors has improved, it is still not completely "out of trouble". According to the financial report data, in the fourth quarter of 2023, Xpeng Motors’s net loss was 1.35 billion yuan, compared with 2.36 billion yuan in the same period last year and 3.89 billion yuan in the previous quarter. In 2023, Xpeng Motors’s net loss was 10.38 billion yuan, while in 2022, its net loss was 9.14 billion yuan, showing an expanding trend.

He Xiaopeng, Chairman and CEO of Xpeng Motors, said, "Xpeng Motors has integrated the intelligence, powertrain and vehicle platform into a large intelligent platform, so as to realize the maximum common sharing among all vehicles. Platform-based R&D and scale effect not only reduce the supply chain cost and manufacturing cost, but also greatly improve the efficiency of R&D iteration, thus enabling Tucki to accelerate the goal of reducing costs by 25%.

Want to challenge BYD with smart driving?

Looking forward to the first quarter of 2024, Xpeng Motors expects its car delivery to be between 21,000 and 22,500, an increase of about 15.2% to 23.4% year-on-year; The total revenue will be between 5.8 billion yuan and 6.2 billion yuan, increasing by about 43.8% to 53.7% year-on-year.

Data show that from January to February this year, Xpeng Motors delivered nearly 12,800 new cars. According to the delivery guideline for the first quarter, the delivery volume of Xpeng Motors in March may be less than 10,000 vehicles.

Investors are also cautious about Xpeng Motors’s future sales prospects and profit plans. "In addition to paying attention to the sales prospects in the first quarter of 2024, investors are also interested in the ‘ that Xpeng Motors plans to launch next month; Cheaper ’ The detailed plan of the model sub-brand is full of curiosity. " Qu Ke, an international analyst at CCB, said.

He Xiaopeng revealed in the earnings conference call: "During the 2024 Beijing Auto Show, Xpeng Motors will officially launch a brand-new brand for the level of 100,000 ~ 150,000 yuan. The first model of the brand new brand will be listed and delivered in the third quarter of this year. "

Gu Hongdi, honorary vice chairman and co-president of Xpeng Motors, said that the new brand will be sold first from the C-end, and then sold in the B-end and other channels a few months after being recognized by consumers. "The new brand model will be successful if it sells more than 10,000 vehicles per month. At present, our production capacity can support this goal." Gu Hongdi said.

It is worth noting that for the market segment of 100,000 ~ 150,000 yuan, new brands such as Wenjie, Ideality and Weilai have not been involved, while traditional brands such as BYD and Geely have not formed the advantage of intelligent driving. Therefore, the industry believes that He Xiaopeng has successfully found the breakthrough point in the cracks — — Play new brands with cost performance, and play traditional brands with smart driving.

National business daily reporter learned that the first model of Xpeng Motors’s new brand will cancel the lidar to reduce the cost of intelligent driving. At the same time, according to He Xiaopeng’s financial report conference call, Xpeng Motors has excellent cost control ability in intelligent driving, and it is expected to achieve the goal of reducing the cost of intelligent driving by 50% in 2024.

However, some people believe that consumers who buy cars in the price range of 150,000 yuan pay more attention to the cost performance, and the ability of intelligent driving has not yet entered the top five decisive factors affecting car purchase. In 2022, Xpeng Motors once put the intelligent driving function in the urban area on the P5 model in Tucki, but the purchase ratio of the actual intelligent driving version was not high.

The number of sales stores will increase to 600 in the third quarter.

In He Xiaopeng’s view, from 2024 to 2027, the elimination of smart electric vehicles officially began. "Xpeng Motors will enter the big product cycle of launching more than 10 new models in the next three years. Together with globalization and upgraded models, the total number of SOP models will reach 30." He Xiaopeng said in the earnings conference call.

When talking about the impact of the intensive release of new products on old products, He Xiaopeng said that the first thing to do after Wang Fengying joined Xpeng Motors at the beginning of last year was to solve this problem. "In order to avoid ‘ Infighting ’ Xpeng Motors will try to avoid the same type of products and there will be fewer car categories. " He Xiaopeng said.

Xpeng Motors’s product planning is regarded as similar to Wang Fengying’s product strategy of "having more children and fighting" when he worked for Great Wall Motor. It is reported that at the beginning of this year, Wang Fengying led a new round of organizational restructuring in Xpeng Motors, which involved product planning. According to industry analysts, Xpeng Motors may sell these models in a way similar to BYD’s sub-network, which is what Wang Fengying is good at.

From the channel point of view, Xpeng Motors is also moving closer to the field that Wang Fengying is good at. It is understood that Xpeng Motors launched the "Jupiter Plan" in July last year, releasing the franchise authorization of dealers and transferring some direct stores in Xpeng Motors to dealers for operation. By December 31st, 2023, there were 500 stores in Xpeng Motors, covering 181 cities.

He Xiaopeng said in the earnings conference call that Xpeng Motors completed a round of channel upgrade in 2023, eliminated more than 130 stores at the end, and introduced more than 160 dealers through "Jupiter Plan". Most of the new dealer stores have been open since the end of last year. It is estimated that the incubation period will take 3-4 months, which will make a significant contribution to the overall sales from April.

In addition, the reporter learned that since the second quarter of this year, Xpeng Motors has set up a channel inventory for about half a month to speed up terminal delivery. "Xpeng Motors will further expand the sales network coverage and accelerate the channel sinking. It is planned that by the third quarter of 2024, the number of sales stores will increase to 600, and it will continue to expand after the listing of new brands to accelerate sales growth. " He Xiaopeng said.

It is worth mentioning that since Wang Fengying joined Xpeng Motors, He Xiaopeng gave full support and authorization to her work, which made the effect of Xpeng Motors’s adjustment appear initially. However, such achievements are only the beginning. Whether the reform led by Wang Fengying can finally help Xpeng Motors get rid of losses and successfully "land" remains to be answered by time and the market.

　　Core reading

　　A few days ago, the Ministry of Science and Technology and other six departments issued a document, focusing on creating a number of major scenarios and expanding the application of artificial intelligence. High-level scientific research activities are one of them. Nowadays, China’s artificial intelligence technology is developing rapidly, and it has advantages in data acquisition, experimental prediction and result analysis. Life science, mathematics, chemistry, space science and other disciplines have embraced artificial intelligence. Rich application scenarios also feed back the development of technology and promote the upgrading of industrial wisdom.

　　From daily life to scientific research, today, China’s artificial intelligence technology is developing rapidly, and data and computing resources are increasingly abundant. Application demand is an important driving force for technological progress, and new technologies are often constantly improved and matured in "use". In order to promote the landing of artificial intelligence, a few days ago, the Ministry of Science and Technology and other six departments jointly issued the "Guiding Opinions on Accelerating Scene Innovation and Promoting High-quality Economic Development with High-level Application of Artificial Intelligence", focusing on creating several major scenes and expanding the application of artificial intelligence. High-level scientific research activities are one of them.

　　As a means of empowerment, how can artificial intelligence bring new research methods, and how can economic development inject "wisdom kinetic energy"?

　　Close integration helps scientific research to be more efficient and accurate.

　　Among many disciplines, life science research and artificial intelligence are closely integrated, and one of the hot directions is to predict protein structure.

　　Protein has a three-dimensional structure, and its primary structure (sequence) is composed of several amino acids in series. The three-dimensional structure determines the function of protein in cells, and many diseases are caused by the important protein structural abnormality in the body. Therefore, only by drawing a "three-dimensional map" of important protein in human body can we find the target of drugs acting on human body, thus developing accurate and effective new drugs.

　　Traditionally, scientists have observed the three-dimensional structure of protein by means of cryoelectron microscopy, X-ray and nuclear magnetic resonance, but this process is time-consuming, laborious and expensive. "Taking the cryomicroscope as an example, it costs tens of millions of yuan to arrange an observation platform, and it will take a long time for researchers to draw the protein structure." He Jingzhou, head of Baidu’s propeller bio-computing platform, said.

　　Due to the high difficulty, long experimental period and high cost, the number of three-dimensional structures of protein observed by traditional methods is very limited. In contrast, amino acid sequencing is much easier. Why can’t we predict the structure of protein based on the amino acid sequence? As early as 1972, American biochemist Christian anfinsen put forward this idea in his Nobel Prize acceptance speech.

　　It is precisely artificial intelligence that accurately predicts the three-dimensional structure of proteins from their primary structure. However, human beings have made slow progress in trying to analyze protein Group. It is explained that, on the one hand, because the existing biological data is small in quantity and low in quality, deep learning lacks enough samples; On the other hand, because the artificial intelligence algorithm is mature, it also needs a process.

　　In recent years, with the sharp increase of biological data and the optimization of artificial intelligence technology, scientists have established more accurate prediction models. In December 2020, in a competition, the artificial intelligence program "Alpha Folding" shined brilliantly, and its predicted results were similar to most experimental data. This proves that artificial intelligence has been quite accurate in predicting the structure of protein.

　　Nowadays, with the help of artificial intelligence, the work that may have taken several years can now be completed in a few minutes, and some protein structures that cannot be observed by traditional methods can also be analyzed.

　　It is understood that using artificial intelligence, researchers have predicted the structure of more than 200 million protein species of about 1 million species, covering almost every protein that has been recorded by the scientific community. This will have a great impact on the field of structural biology, which may lead to a paradigm change in life science research and enhance human understanding of life.

　　It has broad prospects and plays a role in many fields such as life science.

　　Artificial intelligence has entered the field of vision of life science research, and the demand of biomedical industry is an important driving force. According to reports, in the biopharmaceutical industry, the types of drugs that can be developed for every $1 billion invested have been declining. The research and development of new drugs is becoming more and more difficult, and the cycle is getting longer and longer. There is an urgent need for new methods to break through, and artificial intelligence has high hopes.

　　Not only does it accelerate the research and development of new drugs, but artificial intelligence is playing an important role in more and more fields of life sciences.

　　At the beginning of this year, a protein prediction model run by Chengdu Center of National Supercomputing helped the team of Wheat Research Institute of Agricultural College of Sichuan Agricultural University successfully analyze the molecular mechanism of PGS1 regulating seed development and affecting yield, and provided theoretical basis for cultivating high-yield and high-quality wheat materials. Researchers say that without artificial intelligence, it is difficult to make this breakthrough efficiently.

　　Researchers also try to introduce artificial intelligence technology into vaccine design. For example, compared with protein vaccine and DNA vaccine, mRNA vaccine has the advantages of fast mass production and good anti-infectivity, but its stability and immunogenicity are relatively poor. To make up for these shortcomings, researchers have been hoping to optimize the sequence design of mRNA vaccine to make it more stable and more immunogenic. With higher efficiency and lower cost, the intervention of artificial intelligence is expected to provide new ideas for vaccine research and development.

　　Precision therapy is also a stage for the application of artificial intelligence. Through the method of machine learning, in theory, artificial intelligence can decode the human immune system and explore the complex immune laws of some diseases more accurately, thus helping people understand diseases and develop therapeutic drugs and methods more efficiently and pertinently.

　　With the increase of human data and knowledge accumulated in new drug research and development brought by genomics research, and the continuous iteration of machine learning algorithms, industry experts believe that artificial intelligence has broad prospects in the field of life sciences. Some researchers even imagine to build a unified knowledge map by relying on a powerful biological computing engine and using a large amount of biological data to promote the understanding of life and health.

　　Rich scenes, pushing the application to a higher level.

　　Walking into life science research, artificial intelligence brings new methods, and it is also expected to open a new era of biomedical industry.

　　Experts in the industry said that seizing the new opportunities of intelligent drug design and strengthening the layout of artificial intelligence and biomedicine will help us to take the lead in the new track of new drug research and development.

　　Although artificial intelligence+biomedicine has developed rapidly, it has just started on the whole. He Jingzhou believes that the biomedical industry has a history of hundreds of years, with mature and perfect research processes, industrial chains and division of labor. The improvement of artificial intelligence is only some of them. "Biomedical is related to life and health, and the development of the industry should be steadily advanced, maintaining rationality and awe." Up to now, there is no new drug discovered entirely by artificial intelligence in the world. Some products developed by artificial intelligence are still a long way from the real market.

　　Seeing the advantages of artificial intelligence technology in data acquisition, experimental prediction and result analysis, mathematics, chemistry, materials science and space science have also embraced artificial intelligence.

　　The performance of lithium batteries varies with different material compositions. In response to the demand for lithium batteries in a variety of scenarios, researchers hope to design a suitable lithium battery system by optimizing the material combination.

　　"In the past, the design of material systems mainly relied on manual experiments, which was very inefficient." Zhang Qiang, a professor at the Department of Chemical Engineering in Tsinghua University, said that at present, he is leading the team to predict molecular properties with artificial intelligence, so as to find energy materials more efficiently and accurately and design more valuable and safer battery systems.

　　According to estimates, the scale of China’s artificial intelligence core industry exceeds 400 billion yuan, and the number of enterprises exceeds 3,000. Thanks to the strong demand brought by massive data processing and the experimental soil provided by rich application scenarios, China is at the forefront of the world in the fields of computer vision and speech recognition.

　　Experts in the industry suggest that it is necessary to give full play to the advantages of rich application scenarios in China to promote the application of artificial intelligence to a higher level. Creating a major scene around high-level scientific research activities will promote the application of artificial intelligence in China and inject "wisdom and kinetic energy" into high-quality economic development.
