Some experts hold that the younger the better and would get good competence to learn language well, meanwhile others believe that adult have more strong motivation and competence.Based on the Brain Plasticity Theory and the Critical Period Hypothesis, and the intention of this thesis is to reveal such a hypothesis that the younger the learner who starts to learn a second language, the greater performance that he will achieve like a native does, through the comparative research between children and adults. The subjects are 100 Chinese learners who begin learning at different levels and ages. According to the results of integrated scores and a collection of the data in the questionnaire, an analysis show that the results acquired would be consistent with the hypothesis.The intention of this research is not only to argue which is better, earlier or later, but also an trial, through investigation and study, to provide some insights and suggestion to the existent issues, especially the children second language education and college English study in China.展开更多

Taken into account that classroom is the main place in which Chinese college students learn English,it is of great significance to study students' language anxiety in the classroom environment.

It then examines the development of language education system in a new college of a university in China over a period of ten years in relation to the issue of internationalization and globalization.The study shows that the language education system of the new college has developed in parallel with the recently-emerged trends in language education in China. Finally,it seeks to interpret these trends in terms of global,national,regional forces that currently drive it forwards.展开更多

Its effects are irreplaceable and the news language which is a carrier to spread information is in fact influenced by many factors such as society, economy and culture. In order to exert its function to gain different social ends, the presentation of news language owns distinguishing features. This article starts from Verschueren's Adaption Theory to have the final conclusion that the adaption to the social, mental and physical world is the key element for the determination of the originality in news language.展开更多

The design of phonetic teaching calls for more emphasis from English educators since it is one of the basic rounds of English teaching. This paper made a trial on the utilization of TBLTA in the English phonetic teaching context and designed a TBLTA model for English phonetic teaching based on discussions about model and merits of TBLTA.展开更多

Verbal language varies in different cultures, so does nonverbal language. Nowadays more and more teachers have realized the necessity for students to speak the foreign language in class. However, there are still some problems in teaching, studying and testing foreign language, which will be dealt with in this paper. Some teachers speak foreign language with Chinese body language. Thus students, while talking in class,also use Chinese body language to indicate their thoughts. How can't misunderstanding occur when they communicate with native speakers of foreign language? So body language should be set as one of the contents of foreign language teaching. Therefore,body language and courtesies should play an important role in tests.展开更多
