Britain is the country where the Chinese is taught and learnt earlier than other Western countries. Take the students in Confucius Institute of Newcastle University in UK for example, due to the students＇ different backgrounds and also different ages and language foundations, whether the Chinese teaching materials can meet their motivations and needs is a problem worth further investigation by Chinese language teachers. Therefore, concerning the leamers＇ different ages and cognitive ability, this paper aims to analyze the textbook named Kuaile Hanyu （Happy Chinese） in terms of its advantages and disadvantages, in hope to evaluate whether it is appropriate to different learners and propose a few suggestions for the Chinese materials in the future. Simultaneously, fi＇om perspective of implicit learning and explicit learning, a tentative study is carried out on the influence of implicit and explicit leaming in TCFL context.展开更多

Nowadays, some English teachers excessively emphasize the importance of teaching grammar imperceptibly, but neglect to explain the rules of grammar. The diametrically isolation of implicit and explicit learning doesn＇t correspond with the English grammar teaching. So the teachers should combine the two learning styles in order to make the best use of them to teach English grammar.展开更多

Some studies on immigrants show that children of immigrant families who master new languages are more like locals than their parents. Of course, many adults can master a high level of second language. However, compared with the mother tongue (95%), the success rate of second language acquisition is only 5%, considering the children with language disorders. This phenomenon raises the question of the possibility and effectiveness of second language acquisition, especially for adults whose brains have been shaped by first language.展开更多

The simultaneous achievement of expressive emotional talking and accurate lip-sync is particularly difficult, as expressiveness is often compromised for lip-sync accuracy. Prevailing generative works usually struggle to juggle to generate subtle variations of emotional expression and lip-synchronized talking. To address these challenges, we suggest modeling the implicit and explicit correlations between audio and emotional talking faces with a unified framework. As human emotional expressions usually present subtle and implicit relations with speech audio, we propose incorporating audio and emotional style embeddings into the diffusion-based generation process, for realistic generation while concentrating on emotional expressions. We then propose lip-based explicit correlation learning to construct a strong mapping of audio to lip motions, assuring lip-audio synchronization. Furthermore, we deploy a video-to-video rendering module to transfer expressions and lip motions from a proxy 3D avatar to an arbitrary portrait. Both quantitatively and qualitatively, MagicTalk outperforms state-of-the-art methods in terms of expressiveness, lip-sync, and perceptual quality.展开更多
