Based on The Oxford English Dictionary （OED） and the Corpus of Contemporary American English （COCA）, this paper conducts a comparative study of English synonymous verbs deceive and cheat from five aspects: sense evolution, genre distribution, word frequency, collocation, and topics. The results reveal that deceive has more senses that became obsolete than cheat in the process of semantic shifts, so the word cheat has a wider semantic scope in modern English, but both verbs retain the meaning of "To cause to believe what is false" as the chief word sense; different from cheat which is frequently used in oral and informal genres, deceive always appears in formal contexts; the word frequency of cheat is much higher than that of deceive and their inflectional change tendencies are different; deceive often co-occur with topic words related to religion, while cheat is regularly involved in topics like honesty and morality, marriage and ethics. The study aims to clarify the similarities and differences between synonyms deceive and cheat, hoping to provide inspiration for English synonyms teaching and acquisition.

Digital inclusive finance is an important external force to promote the sustainable development of small and medium-sized enterprises(SMEs). In order to explore the role of digital inclusive finance on the sustainable development of SMEs, based on the 2014—2020 financial data of SMEs in the Growth Enterprise Market(GEM), this paper uses the Peking University digital inclusive finance index and SA index, and adopts the fixed effect and intermediary effect model. It empirically analyzes the influence process and mechanism of digital inclusive finance on the sustainable development of SMEs, and conducts robustness test by replacing dependent and independent variables. Finally, it explores the differences in effect of digital inclusive finance on SMEs among industries and regions, and conducts heterogeneity analysis. The results show that: firstly, digital inclusive finance plays a significant role in promoting the sustainable development of SMEs, more than 50% of which have been indirectly affected through easing financing constraints; secondly, through the heterogeneity analysis, it is found that the development of digital inclusive finance plays a stronger role in promoting enterprises, Internet and computer industry in western China. This paper provides enlightenment for the formulation and implementation of digital financial inclusion policies.

In recent years, the research on the concept of cultural memory and its carrier has become a hot topic in academia. The concept of "cultural memory" was first proposed by the German cultural scholar Jan Assmann. He drew the memory discourse into the theoretical framework of cultural studies, and expressed the cultural and identity function of memory from the external dimension of human memory. On this basis, he systematically explained the construction theory of cultural memory. In order to clarify the concept of cultural memory by Jan Assmann, this paper intends to examine the theoretical connotation of cultural memory from the spatial and temporal dimensions. It not only shows the profound space-time contained in cultural memory, witnesses the "inexhaustible visual explosive power in space" and "unweakened continuous ability in time" of cultural memory, and explains the healing power of cultural memory in time and space shuttle. At the same time, with the spatial return and time reconstruction of cultural memory as the breakthrough point, the dynamic process of the spatial and temporal construction of cultural memory is sketched out, and the meaning code of memory is broken, so as to explore the essence and significance of the theory of cultural memory theory.

The practice of this design mode will provide guidance and reference for future poster design, and the methods can promote the diversified development of dynamic poster design.

As the mouthpiece of "telling Chinese stories" and "spreading Chinese voice", international publicity translation is an important bridge of connecting countries with cultural exchanges. Its cultural vitality comes from the translation between different symbols and codes. However, the current research rarely delves into the cultural connotation and significance of publicity translation from the perspective of semiotics. By analyzing the affinity logic between Lotman's cultural semiotics and international publicity translation, the implications of cultural symbols in international publicity translation are deeply described with the theories of "text", "dialogue" and "semiosphere" in Lotman's Cultural Semiotics. The paper makes a layered interpretation of international publicity translation from the four aspects of "meta-language" cognition, "text" implication, "dialogue" interpretation and "chemical" extension, in order to verify the methodological guiding role of Lotman's cultural semiotics in international publicity translation and support the view that Lotman's cultural semiotics is universal in the studies of international publicity translation, so as to further expand the research field of international publicity translation, to enrich the connotation of translation research, and to provide theoretical guidance for the national strategy of "going global" of Chinese culture.

"Wuchang Taiping Lantern" is one of the main types of the national intangible cultural heritage "Dongzhi Lantern". It has a long history and rich meanings. It integrates the original cultural symbols such as folk songs and dances, original crafts and religious beliefs. It embodies the collective memory of the local people and reflects the spiritual outlook of the working people. The research on "Taiping Lantern" takes into account both diachronic and synchronic perspectives. On the one hand, through the description of "space", the research explores its historical origin and reveals its spatial state and regional structure of occurrence and development in "change" and "invariance"; on the other hand, its deductive form is interpreted to decipher the multicultural connotations contained therein, and identify the "idol" and "reality" according to the universality of the ritual, which is beneficial to the exploration of inheritance and the protection of the regional and minority intangible cultural heritage represented by the "Wuchang Taiping Lantern".

In order to solve the problem of high omission ratio of small target objects in remote sensing image object detection, this paper puts forward a small target detection method EfficientNet-YOLOv3 for remote sensing images requiring higher detection accuracy. The method, based on YOLOv3, uses EfficientNet-B0 network to replace the backbone network of the original YOLOv3 algorithm, which can extract image features more effectively, increase the size and number of prediction branches and optimized prior boxes, and improve the detection effect of remote sensing small targets. At the same time, DIoU is selected as the loss function to improve the efficiency of target detection box regression and reduce the omission ratio. Experimental results on DOTA remote sensing image dataset show that the mean average precision mAP of the proposed algorithm is 91.01%, which is 11.82% higher than that of the original YOLOv3. Therefore, it has higher detection accuracy

In modern Chinese, ge can be inserted into some disyllabic words "AB" whose structure is not predicateobjective or predicate-complement, which is called frame construction "A ge B". This paper further summarizes the construction meaning of "A ge B" by sorting out its formation process, and investigates the actual presentation of different construction meanings. "A ge B" is developed from "V ge NP/VP". The invariable term ge inherits and enhances the subjective vivifying function so that "A ge B" has the vivid meaning. In the long-term use and analogy, the action meaning, which "V ge NP/VP" and other former structures as verbal components have, is stabilized, and then "A ge B", itself having the action meaning, is formed. Instances of "A ge B" can present the action meaning because the action meaning of "A ge B" suppresses AB to varying degrees.

Previous literature has demonstrated that the willingness to communicate(WTC) of second language(L2) learners is affected by a variety of factors, among which individual difference factors such as foreign language anxiety and classroom contextual factors such as teacher behavior have been the hot topic. This study aims to develop a hypothetical model to explore the correlations between L2 learners' WTC, foreign language anxiety and teacher immediacy. Questionnaire data was collected from 497 non-English-major college students in Anhui Province and processed in a hypothetical model through measurement and confirmation via AMOS 17.0. It was found that when the foreign language anxiety decreases or the immediate teacher behavior increases, learners' WTC, correspondingly, increases. However, teacher immediacy had no direct effect on foreign language anxiety, which means the immediate teacher behavior failed to alleviate learners' anxiety. This finding, to some degree, bridges the research gap by providing statistical testimony on the factors influencing WTC and sheds pedagogical insights for college English teaching.

In recent years, against the background of building cultural confidence, traditional Chinese medicine cultural documentaries are flourishing. Traditional Chinese medicine culture documentaries with different emphases depict the important influence of traditional Chinese medicine culture on Chinese people in an all-round and threedimensional way, and construct the identity of traditional Chinese medicine culture in line with the current situation. From the perspective of cultural memory, this paper observes the strategies of constructing imaginary space, meaning presentation and identity construction in narrative framework, narrative perspective, ritual tradition,memory field and other aspects of traditional Chinese medicine cultural documentaries, which provides new possibilities for the writing of traditional Chinese medicine cultural documentaries and even the self-transcendence of traditional Chinese culture documentaries. From the perspective of cultural memory, traditional Chinese medicine cultural documentary gradually becomes an expression mode and writing mode of traditional cultural documentary,or has the vitality of cultural construction and the potential of value production.

The historical initiative spirit is the character refined in various historical periods when the CPC led the people to work tirelessly to change the destiny of the nation and the country, is the spiritual key to continue the great rejuvenation of the Chinese nation, and is the logical starting point that conforms to the core values of socialism for the new era youth. The historical initiative of young people in the new era is based on the theory of critically inheriting historical materialism, nurtured on the cultural keynote of China's excellent traditional culture, and born in the historical endurance struggle. The historical initiative spirit and the unique value of ideological and political education of young people in the new era are explored, which are mainly manifested in the cognitive aspect of deepening the quality of historical materialism, the belief aspect of casting historical confidence, and the practice aspect of enhancing historical initiative. In view of this, young people in the new era must strengthen their theoretical abilities and promote the unity of knowledge and practice, learn from models and establish lofty ideals, adhere to the original mission and enhance responsibility, and make good use of historical methods to promote integrity and innovation.

The Cognitive Information Processing Theory emphasizes that career decision-making is viewed from the perspective of information processing, which means the key to improve the job-seeker's ability of career choice is the connotation from accurate "cognition" to career choice. By studying the basic state of college students' career decision-making, through factor analysis, the factors creating college students' career decision-making difficulties are condensed into three aspects: "inadequate preparation", "lack of information" and "emotional factors". Countermeasures are put forward from three aspects: the knowledge domain, the decision-making skill domain, and the execution processing domain.

EFL teachers' agency in intercultural teaching is crucial for cultivating foreign language talents with international visions and global competence. Based on the activity theory, the study explores how a school-based professional learning community facilitates EFL teachers' agency in intercultural teaching. Through the collection and analysis of reflection logs, interviews, classroom observations and other data, it was found that the professional learning community's targeted learning activities centered on intercultural elements, cooperative learning atmosphere, and social network support stimulated teachers' motivation to explore intercultural teaching and learning, facilitated them to construct an intercultural teaching knowledge system, and empowered them to carry out intercultural teaching and research. The study not only explores the facilitating factors the school-based professional learning community exerted to promote EFL teachers' agency from the perspective of activity theory, but provides ideas and methodological references for empirical research on EFL teachers' intercultural teaching competence and professional development.

In recent years, the traditional village tourism development has become a hot issue for scholars. Based on the combing of relevant research literature, this paper summarizes the research progress of tourism development of traditional villages and its impact. The existing research focuses on the protection and development of traditional village tourism resources, diversified tourism development models and the impact of tourism development on protection and development. Tourism, as the main way to protect and develop traditional villages, has effectively promoted the functional transformation and spatial activation of villages, and at the same time, it has brought pressure on the protection of rural landscape and the inheritance of traditional culture. Strengthening multi-disciplinary comprehensive research, and improving research theories and methods; giving full play to the characteristic tourism resources of traditional villages, and exploring the path and mode of traditional village tourism development to promote rural revitalization; cultivating the cultural ecosystem of traditional villages, and coordinating the relationship between protection and development from different dimensions, are the aspects that need to be strengthened urgently in the future research on tourism development of traditional villages.

In modern Chinese clothing words, the words with mao entails abundant cultural and social connotations. According to cognitive linguistics, conceptual metaphor and metonymy are two basic linguistic mechanisms and fundamental thinking patterns. Based on the present corpora, the study approaches the semantic network and extension of the words with mao from the perspective of cognitive linguistics, aiming to disclose their cultural connotations. It is found that the semantic changes of the words with mao are the result of the mechanisms of conceptual metaphor, conceptual metonymy, and conceptual blending.

Raising the level of consumption is an important way to expand domestic demand and promote sustainable economic growth, and it is an important part of the strategy to build a large domestic economic cycle. With the help of big data information technology and innovative traditional financial services, digital inclusive finance can enhance financial inclusion and stimulate the growth of residents' consumption. Based on the panel data of 31 provinces in China from 2011 to 2020, this paper constructs a fixed effect model to study the impact of digital inclusive finance and its first-level dimensions on the consumption of urban residents in China. By building a mediation model, the role of industrial structure in the impact mechanism of digital inclusive finance on urban residents' consumption is examined. The results show that digital inclusive finance, its first-level dimensions and industrial structure upgrading all have supporting effects on urban residents' consumption; the analysis of the role mechanism shows that digital inclusive finance can indirectly promote urban residents' consumption through industrial structure upgrading; the heterogeneity analysis finds that the supporting effect of digital inclusive finance on the consumption of urban residents in coastal, inland, and remote areas decreases in turn.

Music is in the human practice; the exploration of musical beauty depends on aesthetic practice, and musical aesthetic education is an important way to cultivate musical appreciation. Music aesthetic education in the new era is no longer mechanical music teaching based on "supervision"; individual students and social environment are inseparable from the function of music aesthetic education. With the reappearance of body philosophy and the second generation of cognitive science, the body has ushered in the light of "revival" from the gloom of "shielding". The music education in which embodied cognition enters from a brand-new perspective, endows music perception and emotional experience with a unique teaching mode featuring body and mind integration. In the music aesthetic education, we should explore the representation of embodied situation and emotion, construct the music aesthetic education with embodied cognition, and enable students to deepen the beauty of music through the body, experience the music in the situation, and become independent and complete people with physical and mental beauty.

The Chaohu Lake area was the most important battlefield during the Three Kingdoms period, which left a large number of famous military relics, forming a series of belts rich in military cultural resources. The military cultural resources of the Three Kingdoms period in Chaohu Lake area have a complete and clear structure in geographical distribution, which can be summarized as "four cores, three belts and two districts". The types of the military cultural resources are abundant and comprehensive, which include ancient barracks, ancient battlefields, ancient engineering, ancient relics, ancient tombs, military traffic, military thoughts, historical stories, famous images and historical events. Studying the types of military cultural heritage in the Three Kingdoms period around Chaohu Lake can help promote the inheritance and protection of military cultural heritage.

The finite element analysis of the Baja racing car's brake and its connection piece has been completed. The UG software is used to establish the connection piece 3D model, which is imported into ANSYS workbench to carry out its structural statics analysis, and the structure of the connection piece is checked and optimized. The main improvement scheme is to add ribs in places where stress concentration occurs and to hollow out properly. The modal analysis of the brake disc is carried out; the natural frequency of the brake disc is calculated, and the vibration mode is analyzed. The results show that the reason for the brake disc falling off is not the resonance torsion between the brake disc and the outside world, but the brake disc is subjected to a large axial force when driving, which acts on the rivet connecting the brake disc and causes the rivet to fail. The analysis results can provide reference for the design of the Baja racing car's brake and its connection piece.

Shimaki Kensaku's The Quest for Life was written during the heated period of Japanese militarism, and is a masterpiece of "Tenko Literature". The theme of the novel is the exploration of how to reconstruct identity after one's renunciation of Marxism. It is a very special Bildungsroman in a reactionary era. The novel is about a young intellectual's journey to reconstruct his identity through social practice and personal cultivation in a political system where free will has been harshly destroyed. Shimaki's tenko writings are different from other tenko literature. Through providing an insight into the internal causes of political conversion, as well as a detailed and realistic portrayal of rural life, it subverts the discursive order of "Political Conversion = Defection", unites reason and emotion in a seemingly apolitical way.

By comparing the topological characteristics of various DC/DC converters, an isolated bidirectio nal bridge DC/DC converter （BDC） with high power supply and transformer utilization and high power d ensity is selected; in order to improve the voltage gain and energy transmission efficiency, the resonant t ype is improved. BDC; in order to achieve consistent bidirectional operating characteristics and soft switc hing function, it is further improved to CLLC resonant BDC; in order to achieve constant voltage gain a nd transmission efficiency under frequency offset, a frequency tracking CLLC resonant BDC is finally de signed. The simulation results show that the frequency-tracking CLLC resonant BDC designed in this pap er can maintain high voltage gain and energy transmission efficiency under a large frequency range offset, no matter it is forward transmission or reverse transmission, and the bidirectional transmission characteris tics are basically Consistent.

Governor and grand secretary is known as a grand secretary who also serves as a local governor. As the reform and innovation of the system of grand secretaries by the Yongzheng and Qianlong Emperors, the governor and grand secretaries first appeared in the late years of Yongzheng period, and they were active in the middle and late Qing dynasty. By analyzing the information of 12 governor and grand secretaries in Qianlong period, including their employment background, official career and on-duty information, this group turned out to be a high-quality bureaucratic group with outstanding ability, great military achievement, and abundant experience. They were the division and extension of imperial power, and played an important role in stabilizing the inner court and the outer court.

After the 21st century, due to the huge social changes in China, there are various uncertainties. While enjoying the achievements of social development, we are also facing a large number of potential social risks. Resilient cities and community resilience can effectively cope with risks, improve the level of governance, and promote urban development. This paper takes the rainstorm and flood risk of W community in Chaohu City as an example to analyze the resilience construction of W community from three aspects of economic development, social capital and community capacity from the perspective of resilient city. The study found that the development of economy, social capital and community capacity plays an important role in improving the stability, recovery and adaptability in coping with disasters, and as a result of community resilience construction, it can build a "resilient city" from the four dimensions of environmental resilience, institutional resilience, community resilience and individual resilience, and improve the modernization level of urban safety governance.

By studying the status of the development of higher education in China, this paper finds that there are the following problems in the current training of talents in higher education: lack of innovative talents, uneven distribution of talents, insufficient efforts in talent training, low utilization rate of development and lack of a good research environment; At the same time, it is also found that in the construction of quality higher education, there are a series of problems, such as the lack of funding and the decline of enrollment quality. In addition, there are also many defects and deficiencies in the quality evaluation of higher education. In view of the above situation, this paper uses principal component analysis to estimate the weight, constructs the intuitionistic fuzzy comprehensive evaluation model, and makes a comprehensive evaluation on the educational quality of "double first-class" universities in China. The study finds that about 48.7% of people think that the current "double first-class" universities have
excellent education quality; 31.9% think that the education quality is good; 19.3% think that the education quality is medium; 0.12% think that the education quality is poor. Finally, some policy suggestions are put forward.

The effective cultivation effect of college students' spirit of rule of law is conducive to promoting the process of comprehensive rule of law. Comprehensively promoting the rule of law and the cultivation of college students' spirit of rule of law complement each other. Against the background of ruling the country by law comprehensively, cultivating college students' spirit of rule of law needs to take systems theory and synergy theory as the theoretical basis, and build a government under the rule of law to provide a practical model for it. In the process of cultivating college students' spirit of rule of law, the cultivation subjects are diverse, but there is a lack of integrity and synergy among the diverse subjects. Regarding how to enhance the synergy of the cultivation subjects, this paper takes the synergy theory as the research perspective and puts forward the establishment of collaborative policies for the cultivation of college students' spirit of rule of law from the perspective of multiple subjects, so as to improve the synergy and linkage of cultivation, and enhance the effect of the cultivation of college students' spirit of rule of law.

Rapid detection of sulphonamide antibiotic contamination in the environment is important for water environment monitoring and management. To fabricate carbon quantum dots based fluorescent molecularly imprinted sensor（CQDs-MIP） with specific recognition ability for sulfamethazine, nitrogen-doped carbon quantum dots, 3-aminopropyltriethoxysilane, ethylene glycol dimethacrylate and sulfamethazine were used as the fluorescence source, functional monomer, cross-linker and template molecule respectively. The effects of functional monomer addition, solvent type and cross-linker type on the performance of CQDs-MIP were investigated by adsorption experiments. The experimental results showed that the adsorption process of CQDs-MIP on sulfamethazine was in accordance with the Langmuir adsorption isotherm model and the second-order kinetic equation, and showed high selectivity for sulfamethazine with the selectivity coefficients of 2.28 and 3.02 with respect to sulfadiazine and sulfadimethazine, respectively. The linear range of CQDs-MIP for sulfamethazine was 2~100 mg·L^-1 with a linear correlation coefficient of R² = 0.9972; CQDs-MIP has the ability to detect sulfamethazine rapidly and sensitively.

Abstract:The current curriculum setup and teaching of history major in normal universities lack the cohesion with history teaching in middle schools, and the form and content of teaching practice lag behind, which leads to the fact that the educational concept of normal students cannot keep up with the requirements of the curriculum reform in middle schools when they enter the profession, and that teaching design is impractical, professional knowledge is not solid, and classroom control ability is insufficient. Based on the requirements of the Ministry of Education in The National Standard for the Teaching Quality of Undergraduate Majors in General Institutions of Higher Learning,The General High School Program 2017 Edition, and The General High School History Curriculum Standard 2017 Edition, normal universities should establish a scientific outlook on education, based on the lifelong development of students, and reasonably construct the curriculum system of history specialty. The interactive mechanism of teachers should be established between universities and basic education institutions. Through the "double-entry project", the interaction of teaching and scientific research should be realized, the long-term mechanism of curriculum development and quality control should be established, and the teaching practice mode of normal students should be innovated. We will work hard to improve the training quality of history professionals.

The course reform of higher education is a breakthrough to realize the construction of "gold course" and "first-class course". The current course reform of higher education is in full swing. How to grasp the problems behind the hot spots of course reform of higher education, clarifying the future issues of higher education course reform is the basis of promoting the construction of high-quality curriculum in colleges and universities. Based on the 2296 academic papers from 2015 to 2020, the keyword cloud graph analysis, knowledge map analysis, cluster analysis and trend analysis were carried out by using SATI3.2 and R software. It is found that the course reform of higher education in the past five years has several characteristics: There is no obvious difference between different types of course reform; the course reform mainly focuses on the teaching modes of mixed or flipped classroom and massive open online course; synchronism of course reform and talent training goals has not been paid enough attention. Under the standard of "gold course" and "first-class course" construction, the higher education course reform should focus on the education idea, faculty building, teaching mode, comprehensive course management, goal-oriented reform, so as to develop high-quality courses.

In the Qing Dynasty, a group of scholars who made great achievements in the field of arithmetic emerged in southern Anhui, forming a distinctive Anhui school of mathematics. Within the school, knowledge was transmitted directly by means of family chains and teacher-friend chains. The dissemination and communication also rely on reading, mutual commentary, debate, mutual collation, contribution of prefaces or postscripts, etc. The diversity of communication brought prosperity to the Anhui Mathematics School. In addition, Anhui Mathematics School also interacted with scholars outside Anhui province in a similar way, most of whom are from neighboring provinces of Anhui, which proves the regionality of the academic dissemination and communication. Though this rather closed circle confined the expansion of Anhui Mathematics School as well as its academic broadcasting, it is also conducive to the formation of distinctive academic views and its traditional self-identification.

Psychological resilience is an important symbol of individual mental health, and it is also a kind of resilience that individuals show in the face of adversity. Psychological resilience provides an effective theoretical framework for studying tourists' coping with external risks. In the context of COVID -19, Fuzzy -set Qualitative Comparative Analysis(fsQCA) was used to explore the combined effect of factors influencing tourists' psychological resilience. The results show that: There are three types of patterns that lead to the decrease of the psychological resilience of tourists, which are "uncertainty—negative coping oriented", "personality trait conditioned" and "neuroticism—negative coping oriented". There are three types of patterns that promote the psychological resilience of tourists, which are "social support leading", "positive coping leading" and "external support—positive coping oriented", among which the combination of family support, social support and positive coping style is the optimal path. Based on the asymmetric causality theory, this paper explains the configuration effect of interdependence among conditions, which provides theoretical support for how to improve the psychological resilience of tourists during the epidemic.

Current studies on the effect of L2 Motivational Self System(L2MSS) on college students' motivational behaviors are rare. A mixed qualitative and quantitative analysis with 162 college students from a mobile learning course called Youlinyouke was conducted to explore the influence of L2MSS on students' motivational behaviors and its difference from offline learning context. The results indicate that, on the one hand, the L2MSS in the mobile context has an effect on college students' motivational behaviors, with the L2 learning experience having a significant positive effect, the ideal L2 self having a moderate positive effect, and the ought-to L2 self having no effect; on the other hand, different from the effect in offline learning context, the function of learners' L2 ideal self on motivational behaviors is weakened but the effect of L2 learning experience is reinforced. A thorough grasp of the effect of the L2MSS of college students in the context of mobile learning has significant implications for promoting mobile English course design, mobile English teaching practice, and educational equality.

Journal covers are usually the kind of multimodal discourses combining images and text symbols, which play active roles in the construction and communication of national images. Based on the framework of visual grammar theory, this paper conducts a meaning analysis of multimodal symbols of technology-themed front covers of Beijing Review published from 2012 to 2021, and examines the visual framing of image symbols, so as to reveal the meaning presentation and construction of China’s technological images with the integration of linguistic texts. The result shows that the technology-themed front covers of Beijing Review mainly employ three kinds of visual frameworks including innovation, driving and empowerment. Through the three meta-meanings of representation, interaction and composition in visual grammar, the front covers present the real scenes of China’s technological images, innovate the visual symbols for the international communication of China’s technological images, and construct the technological images of China in harmony with the era.

College students' anxiety is influenced by various factors, with stress perception being a prominent and challenging area of research. This study aims to explore the relationship between stress perception and college students' anxiety, as well as its underlying mechanisms. Using a survey method, data were collected from 1 009 college students to establish a model linking stress perception, smartphone addiction, insomnia, and anxiety. The findings indicate a strong correlation between stress perception and anxiety among college students. Specifically, stress perception can trigger anxiety through the sequential effects of smartphone addiction and insomnia. Theoretically, this study contributes to understanding the intrinsic mechanisms by which stress perception affects anxiety, enriching the theoretical framework in this field. Practically, it underscores the importance for college authorities to recognize the detrimental impact of stress perception on students忆 anxiety and to adopt a collaborative, multi-faceted approach to prevention and intervention.

Jia Pingwa has created the image of the wise man in more than ten texts, which shows the author's preference for the image of the wise man. The wise man has different cultural connotations in novels of different periods and themes, which can be roughly divided into three series. First, in the novels of seeking roots in the 1980s, the wise man showed the introverted and deep, silent and powerful national spirit. Second, in the country novels after the 1990s, the wise man metaphorically described the process from hardship to gradual decline of Chinese traditional country culture under the impact of modern civilization. Third, in historical novels since the new century, the wise men, facing wars, killings and distortion of human nature, showed the light of human nature and soul comfort beyond history.

Constructing a regional innovation ecosystem has become a pivotal strategy for achieving regional collaborative innovation and bolstering national innovation capacities. This study, grounded in the perspective of innovation ecology, selects 31 provinces and cities in China as case study subjects. By integrating Necessary Condition Analysis （NCA） and Qualitative Comparative Analysis （QCA）, it examines the relationship between the regional innovation ecosystems and regional innovation performance from a configurational perspective. The findings reveal that: A comprehensive network of technological innovation entities is a necessary condition for driving high regional innovation performance; There are three pathways to achieving high regional innovation performance: "Knowledge Innovation Entity–Balanced Type", "Technological Innovation Entity–Balanced Type", and "Collaborative Symbiosis–Balanced Type", and five pathways leading to non-high regional innovation performance, with an asymmetric relationship between them; Under certain conditions, there exists a substitution relationship among innovation entities, and between innovation entities and the market environment. Furthermore, this study provides strategic insights and potential measures for optimizing regional innovation layouts, creating regional economic growth poles, and exploring the types of regional innovation ecosystems that can more effectively enhance regional innovation performance, thereby facilitating high-quality development in different cities.

The different English versions of Wang Yue can meet the reading needs of different reader groups. Based on three English versions of Wang Yue, drawing on the Prototype-model Translation Theory, this paper introduces the translation concepts of "fitness" and "faithfulness" and readers' satisfaction, and reaches the following conclusions by using the research method of translation comparison: Xu Yuanchong's version can meet the reading needs of professional readers; Sun Dayu's version can meet the reading needs of non-professional adult readers; The version by Stephen Owen can meet the reading needs of non-professional children readers. Therefore, the article holds that only by using appropriate translation strategies to faithfully translate the writing features of the source text, and only by "adapting" to the reading needs of different reader groups, can different versions coexist because they fit the reading needs of different readers.

The secret society was an influential civil force in modern Yunnan, which played multiple roles in the changes of times. The secret society in Yunnan was introduced from neighboring provinces. After entering modern times, it took root in the soil of semi-colonial and semi-feudal society and developed rapidly. In order to resist the oppression of the government, the Yunnan secret society launched several uprisings and shook the rule of the Qing government in Yunnan; In order to establish a democratic political system, the Revolutionary Party headed by Sun Yat-sen noticed the great power contained in the secret society and the special geographical location of Yunnan. They used the secret society to launch numerous armed uprisings and accelerated the collapse of the Qing government. At the end of the Qing Dynasty, the Yunnan secret society also expanded its forces in the old and new armies and served as one of the main forces in the movement of uniting the bourgeois revolutionaries to overthrow the Qing government. However, due to its own defects and the completion of the "anti-Qing Dynasty" goal, the Yunnan secret society was suppressed by the military governor just after the Xinhai Revolution of 1911.
