“What are you/we talking about?”是英语口语交际中常见的习语构式,不仅具有规约意义和语境制约下的语用意义,而且用来调节和管理前述话语与交际行为,属于元语用意识指示语。本文基于元语用理论,通过分析美国当代英语语料库口语子库... “What are you/we talking about?”是英语口语交际中常见的习语构式,不仅具有规约意义和语境制约下的语用意义,而且用来调节和管理前述话语与交际行为,属于元语用意识指示语。本文基于元语用理论,通过分析美国当代英语语料库口语子库中构式“What are you/we talking about?”的语用意义,揭示其在不同语境下说话人的元语用意识体现。研究发现,构式“What are you/we talking about?”体现说话人对交际中语篇、信息、发话人和交际双方四个维度的元语用意识,具体表现在管理话语组织结构,为听话人提供认知解读框架,构建权威身份,管理人际亲疏关系。本研究拓展了构式研究的理论视角,对构式的元语用阐释有助于我们更全面地推理和解读说话人的交际意图。 展开更多

This paper proposes a technique for synthesizing a pixel-based photo-realistic talking face animation using two-step synthesis with HMMs and DNNs. We introduce facial expression parameters as an intermediate representation that has a good correspondence with both of the input contexts and the output pixel data of face images. The sequences of the facial expression parameters are modeled using context-dependent HMMs with static and dynamic features. The mapping from the expression parameters to the target pixel images are trained using DNNs. We examine the required amount of the training data for HMMs and DNNs and compare the performance of the proposed technique with the conventional PCA-based technique through objective and subjective evaluation experiments. 展开更多

The theme of this year' s World Metrology Day is 'Metrology and Energy'. Theenergy problem is an important issue for the whole world and has received great attention in Chinasince China is both a big energy-consuming country and a country severely short of energy. Under theenergy and environmental pressure, China will take measures in the following four respects in orderto solve the problem of energy shortage: China will stick to the self-reliance principle for energysupply, since China has abundant coal resources, which have formed the mainstream of its energysupply. The coal resources account for 67 percent of energy supply and the self-reliant supply rateof coal has reached as high as 94 percent. China will take action to tap more resources and saveenergy consumption. China will attach greater importance to the development and exploitation ofrenewable energy resources. China will conduct international cooperation at an appropriate level. 展开更多

This paper is mainly discussing about the significance of the Living Educational Theory Action Research raised by Dr. Jack Whitehead, also it gives a clear distinction between traditional AR Theory and that in the LETAR. Because of the distinctive features like "individual", "living" and "practical" characteristics been embodied in the Living Educational Theory, it can be very well applied in the character education of improvement in the individual and group practice, therefore, implementation of the "New Curriculum" as a case to prove what has been discussed. 展开更多

Language errors are significant in three respects: they tell the teacher what needs to be taught; they tell the researcher how learning proceeds; and they are a means whereby learners test their hypothesis about the second language( Corder, S.P. 1967) Learning to swim, to play tennis, to type, or to read all involve a process in which success comes by profiting from mistakes, by using mistakes to obtain feedback from the environment and with that feedback to make new attempts which successively more closely approximate desired goals.However, getting the learners to communicate at all costs may cause the fossilization of language. 展开更多
