It is...In order to provide English as a foreign language students with effective English language learning approaches, this investigation is focused on how students deal with words when they are doing reading material. It is found that most students can use some skills to guess the unknown words in reading materials, such as explanatory analysis skills, syntactic analysis skills, and structural analysis skills, while they have overlooked how these words are organized metaphorically and metonymically. This investigation will provide students with the target language knowledge metaphors and metonymy, examining the impact on computer vocabulary guessing and reading comprehension through teaching the concept of metaphor and metonymy. In this research, the new word-guessing skill based on the knowledge of metaphor and metonymy was applied to word-guessing teaching in reading comprehension of computer material. The research question is studied in this experiment: Can the training of using ways of word-guessing base on the knowledge of metonymy and metaphor promote students' ability of word guessing in reading comprehension of computer material? The results show that students have gradually paid attention to the word-guessing skill in reading process. The skills based on the knowledge of metaphor and metonymy have helped students get the right meaning of the unknown words in computer reading materials. It has really enlarged students' vocabulary and improved their confidence in finishing reading.展开更多

There were 134 Iranian male and female learners participating in this study. A SCIA questionnaire containing 30 items was developed and validated to assess EFL learners' preferences for intervention categories. Moreover, Myers-Briggs Type Indicator (MBTI) was used in the research. Results indicated that whereas in some cases no significant differences were observed, there mostly existed numerous significant differences among language learners with different personality traits and their preferences for SCIA.展开更多

The research is a part of the English Learning Program directed by ZHANG Zhen, which is sponsored by Academic Affairs Office of Leshan Normal University. The researcher of the program sought for theretical bases from Krashen's Input Hypothesis, the Motivation Theory, the Context Theory, and the Communicative Language Teaching Theory. Then the author introduced a pilot study conducted by utilizing films or TV programs to teach listening from September 2010 till now. The statistic results from the experiment suggest that there is indeed some correlations between teaching listening with films or TV programs and a learner's listening comprehension in general in language achievement tests at certain stages. The scores of the students from the experimental group are improved after two years of teaching with the new methods. Analyses and discussions have been done based on a questionnaire and an interview. The results showed that both the teachers and the students had positive attitudes towards teaching listening with films or TV programs. Most of them view this method as an effective way in ELT (English language teaching), because it provides more opportunities for contextual practice, lower their anxiety; it can also help to motivate them, stimulate their active participation and increase their activities as well. Therefore, this method can be used to cultivate students' communicative competence. Consequently, we can draw the conclusion that this method has some advantages over teaching listening with the pre-taped materials in New College English. It may play an important role in ELT, especially in listening teaching. Based on the statistic analyses and the survey, some activities and techniques are provided for the teacher on how to teach listening with films or TV programs. The roles that an English teacher plays in this method are illustrated at the end of the thesis.展开更多

The paper introduces initial notions on applying linguistic criteria as the basic ones in the process of creating ME textbooks. Through the historical development and under the influence of extra linguistic factors (globalization of the shipping industry, in particular), ME has accumulated and stored various resources being in current use: vocabulary, grammar and phonology, operational and semiotic systems, specific means of communication, functional models, patterns of narration and description, etc.. The proper linguistic analysis makes a secure foundation for methodology which can guarantee a better quality of ME course books for the 1st and 2nd year maritime students all over the world.展开更多

As an applied linguistics course, stylistics is eminently suitable for study and analysis of literature, because it clearly explicates literary effects through linguistic analysis. Many scholars have illustrated the use of stylistics analysis for the purposes of studying literature and teaching it, which is, pedagogical stylistics. However, this paper combines both the study of Stylistics as a discipline, which is the pedagogy of Stylistics, and the use of stylistics for teaching literature in general and poetry in particular. Namibia adopted English as its official language 22 years ago. Since then, both teachers and students have been struggling with the analysis of poetry. This study is an empirical one using qualitative methods in the author's research to determine the impact of the study of Stylistics on the understanding and teaching of literature in Namibia. The author uses traditional British poetry from the 16th century up to the 20th century alongside postcolonial poetry to assess the importance of culture in understanding poetry and examine the advantage of using stylistics to teach the poems that the author selects.展开更多

Usually approached from the angles of linguistics, sociology and psychology, CDA aims to uncover through analyzing linguistic forms, the relations between language and ideology. By applying the specific methods of transitivity, transformation, modality and classification in CDA to a report on Barack Obama in The New York Times--a mainstream media in the United States, this paper aims to reveal the ideology hidden in the report, so as to raise the readers' awareness of perceiving unconscious ideologies in news and help them to have a deeper understanding of news and the language in news.展开更多

But the differences in the Chinese spoken dialogue system are not as distinct as that of English. In Chinese spoken dialogues, there are many language phenomena. Firstly, most utterances are ill-formed. Secondly, ellipsis, anaphora and negation are also widely used in Chinese spoken dialogue. Determining how to extract semantic information from incomplete sentences and resolve negation, anaphora and ellipsis is crucial. SHTQS (Shanghai Transportation Query System) is an intelligent telephone-based spoken dialogue system providing information about the best route between any two sites in Shanghai. After a brief description of the system, the natural language processing is emphasized. Speech recognition sentences unavoidably contain errors. In language sequence processing procedures, these errors can be easily passed to the later parts and take on a ripple effect. To detect and recover these from errors as early as possible, language-processing strategies are specially considered. For errors resulting from divided words in speech recognition, segmentation and POS Tagging approaches that can rectify these errors are designed. Since most of the inquiry utterances are ill-formed and negation, anaphora and ellipsis are common language phenomena, the language understanding must be adequately adaptive. So, a partial syntactic parsing scheme is adopted and a chart algorithm is used. The parser is based on unification grammar. The semantic frame that extracts from the best arc set of the chart is used to represent the meaning of sentences. The negation, anaphora and ellipsis are also analyzed and corresponding processing approaches are presented. The accuracy of the language processing part is 88.39% and the testing result shows that the language processing strategies are rational and effective.展开更多

We can not imagine the world without advertisements. Advertisers try every means to design persuasive advertisements for their products by attractive patterns, photos and colors, as well as commonly shared resources of language. The use of presupposition in advertising language, which is an important topic in pragmaties, can serve the function fairly well. This paper first presents a general review of previous studies on presupposition phenomena in advertising language, then investigates the use of presuppositions in advertising language by both qualitative and quantitative analyses. By qualitative analysis, the author tries to explore the functions of each type of presuppositions in advertising texts; by quantitative analysis, 100 sentences selected from various advertisements for different products are examined.展开更多

More people cross borders of nations, leave their homeland and live in new homes, but they still maintain the characteristics of native culture and convention. The cultural turn in translation studies offers the best chance to understand more about the complexities of textual transfer and the patterns of cultural interaction. By virtue of this mode of cultural interaction, this paper has analyzed the translation practice and translation strategies from the cultural diaspora perspective, to deeply understand the relations between translation and culture beyond linguistic analysis. As in-between culture identity translators may re-examine two cultures with different eyes to find the intersection of two cultures and gain a balanced point. This move requires translators who play the role of intermediaries between cultures, to select the heterogeneous reconstruction, so as to achieve the intercultural communication in the translation activity展开更多
