Both signed and oral language interpretation are activities that convert one language into another. They are similar with each other in terms of interpreting strategy, model, skills and so on. Sign language interpretation teaching and research can be integrated with oral interpretation teaching and research. China today urgently needs more multi-talented people than skillful language users. This paper holds if English majors learn signed language and can interpret between CSL, Chinese, and English, they must be warmly welcome in the employment market. Such interpreters with compound abilities are able to bridge the gap between hearing and deaf people even from different countries. This is of necessity and feasibility.展开更多

However, different countries have their own language habits and communication methods. It is difficult to communicate through their own languages. It is necessary to have a language that can be used globally. As a universal language, English is widely used in communication activities. This kind of communication can't be directly translated by the communicators for a long time, and should be carried out with the help of corresponding English interpreters. Therefore, this requires interpreters to have professional quality and master skilled interpreting skills in order to ensure smooth communication.展开更多

How to help students overcome state fright and adapt to the actual scene of interpreting has been a major concern for professors and teachers. Psychological quality, which is as important as other interpretation skills, such as listening, is a premise of a successful and qualified interpretation. This essay will analyze how to educate a qualified interpreter in terms of psychological quality by various aspects, including putting more emphasis on bilingual learning, enriching students’ cultural connotations, enhancing teachers’ comprehensive quality, cultivating students’ English public speaking ability, creating authentic interpretation environments, improving students’ adaptability of different interpretation environments, and using other practical skills.展开更多

This paper investigates the characteristics of the notes taken by student interpreters in relation to the output and the process of interpretation with the purpsoe of identifying the role of note-taking in the process of interpretation, its relations with the production quality, and the factors that constrain the development of the students＇ potential as future interpreters. Statistical and qualitative analysis of the notes and think-aloud protocol reveals that students majoring in English should further improve their overall English proficiency. Note-taking, either in source language or target language, or both, should be practiced until students are able to use it expertly. Inspite of the importance of note-taking in interpretation, students should be trained to rely more on memory rather than solely on the notes.展开更多

These interpreters made the Sino-US alliance a reality by enabling American servicemen to communicate with other Chinese. But despite the program＇s operational success, interpreters suffered from intractable morale problems. Interpreters began their service with lofty expectations. Senior officials and intellectuals encouraged them to see themselves as central figures in China＇s struggle for nafonal rejuvenation. They would uplift the country by convincing American servicemen to see Chinese as equals and by introducing American technology, traits, and habits to the Chinese Army. It all sounded glorious to cadets undergoing training, but actual interpreter service proved bitterly disappointing to most young men. They found their monotonous duties unworthy of their position The Nationalist government, for its part, lacked the capacity to keep them clothed, paid, and fed. Their own compatriots--soldiers and civilians alike--regarded them with suspicion. Most frustrating of all, American soldiers refused to treat them as equals. By examining interpreter morale problems in China fronl 1941 to 1945, this article enriches our understanding of wartime interpreting, China in a global World War II, and sources of friction in the Sino-US alliance展开更多
