The analysis shows that all the subjects need to improve the Basic English language skills and knowledge. In-service training and retraining are the effective ways to help develop their professionalism, but due to the limitations of all kinds of obstacles, their learning needs cannot be met. Only by the concerted efforts by the society and the teachers themselves, the problems arising in their professional development can be solved.展开更多

However, they are not entirely identical in Path encoding. Path comprises Vector, Conformation, and Deictic. Vector comprises Arrival, Departure and Traversal. English and Chinese use different forms (prepositions vs. verbs) to represent Traversal. The Arrival component in Chinese can denote "realized arrival" while that in English cannot. English is not fine-grained as Chinese in the specification of Conformation. The use of Deictic in Chinese is more pervasive than that in English. Satellite elements in English are realized as particles and prepositions while those in Chinese are realized as directional verbs.展开更多

Chinese Language and Literature is as a strong tradition of employment facing unprecedented challenges. Based on the severe employment situation, Teacher Education in Local Comprehensive Universities need to start improving their own quality of graduates, and actively guide the graduates to change jobs ideas, updating the concept of employment, and use existing resources, and actively expand employment channels, and explore new ideas and open up new market, employment path is becoming more diverse to ensure employment stability and sustainable development.展开更多

As a special temporary or local ambiguity in language processing, it has been widely explored and studied from aspects of semantics, syntax, pragmatics as well as psycholinguistics and cognitive linguistics over the years, since it was first put forward by Bever in the 1970s. The research of garden path phenomenon is of considerable significance both theoretically and practically. This paper is designed to explore the garden path phenomenon in English through literature and examples. Some basic concepts and main triggering factors of garden path phenomenon are analyzed. This paper explores the triggering factors of garden path phenomenon from the aspects of syntax, semantics, and pragmatics. The major finding is that garden path phenomenon can help learners understand the operation of human language processing mechanism and improve their abilities to deal with garden path sentences, which is of great benefits to learn and understand English language.展开更多
