Conceptual metaphors belong to traditional vocabulary metaphors, and ideational grammatical metaphors are pointed out by Halliday--the main representative of systemic-functional theory. This paper elaborates on the specific grammatical feature of EST (English for Science and Technology) text--"nominalization of processes" to reveal the source of ideational metaphors. From the analysis of some examples, it is found that nominalization as a grammatical metaphor expresses the transference between process types, so it reveals the essence of ideational grammatical metaphors. Meanwhile, the comparison made between grammatical metaphors and vocabulary metaphors reflects the similarities between conceptual metaphors and ideational metaphors. In this way, this paper comes to the conclusion that the combination of the study methods of metaphors from both cognitive and systemic-functional perspectives is the best way to uncover the basic characteristic of human thinking.展开更多

However, in the field of the concession addresses, the studies on this kind of political text are limited. The winners of presidential election always draw much attention from the world and their speeches, for example, presidential inaugural address has been a hot study topic of linguistics. Nevertheless, the losers of presidential election are always neglected by the world and the study on concession address is scarce and rare. Therefore, the meaning of study on the concession speech helps fill the gap of the discourse analysis. This thesis applies the PDA under the framework of appraisal theory to analyze five concession speeches with a combination of qualitative and quantitative approaches. This study aims to complement CDA (Critical Discourse Analysis) to emphasize positive social construction of political discourse.展开更多

The autonomy of each unit was investigated in this foundation. The system unit was described using the Web Ontology Language (OWL) ontology. And the system semantics was also integrated. On these basics the communication among the system units was analyzed with an example of interaction between a machine and a warehouse. The control performances of information system units were investigated using Boolean matrix as a substitute for traditional process in RW theory, which reduced the computational complexity. This work established the foundation for the demand analysis, design and development of the distributed manufacture information system.展开更多

The use of words to represent the document content and query generates several problems, the ambiguity of words and their disparity. The semantic indexing is as a solution that answers these problems. The goal context where the ambiguity is present, the semantic indexing is meant is to index by the meaning of words rather than words. In a to improve the performance of IRS (Information Retrieval System). In this sense we will soon overcome the problems of traditional indexing approaches. What we propose is a new approach that will allow semantically indexing algorithms courses written in French language, based on a new application ontology. The aim of our approach is to adjust a semantic annotation tool with the reference ontology. The semantic annotation tool we generate an index that will be used in e-Learning as needed (question answering performance on the field. systems, information retrieval systems ) while improving展开更多

We provide the whole process of design and development in online speaking exam, illustrate several functional designs including item bank construction, auto-generating examination paper and test paper analysis and discuss various network programming development technology during teachers' speaking network examination intensively. Directed by software engineering theory, the system is finally designed and realized through feasible research, requirement analysis, general design, detailed design, and tests with popular system development language and powerful database management.展开更多

AT and the Activity System (AS) model developed by Engestrom are widely used in a variety of fields in social sciences. In this paper, I consider how the AS model and the concept of "object" in particular can be adopted when researching the complexity and dynamics of teaching activity and its outcome on a phonetics course at a university in China. The findings indicate that varied "object" that each individual student is working at during the teaching and learning activities constitutes an important and direct factor leading to differentiated learning outcome in the phonetics course. A thorough examination of the relationship between the components of the AS reveals ways of narrowing the gap between the collective "object" that is constructed publicly and explicitly during the lesson and the individual "object" constructed silently and implicitly by each individual. The author argues that the closer the collective "object" is to the individual ones, the more rewarding a lesson will be to the majority of the students. Thus it is the teachers' responsibility to identify various individual "objects" and to bridge the gap between the collective and individual "objects" in order to improve the quality of classroom teaching and learning.展开更多
