核心具有向结构体渗透范畴特征的属性。汉语词缀＂-子、-儿、-头＂具有构词平面的名词化作用,后附成分＂的＂也具有改变词类的作用,从核心理论来看,实际上就是因为它们是所在结构的核心。汉语也存在词与短语的转类现象,即在不改变形式的情况下出现范畴的改变。词的转类使词的词类发生变化;短语的转类一般不会造成词类的改变,所以处于主宾语位置与定中结构中心语位置的动词形容词仍旧为动词形容词。转类是由零词缀引起的。 相似文献

This study was an attempt to identify the epistemological roots of knowledge when students carry out hands‐on experiments in physics. We found that, within the context of designing a solution to a stated problem, subjects constructed and ran thought experiments intertwined within the processes of conducting physical experiments. We show that the process of alternating between these two modes — empirically experimenting and experimenting in thought — leads towards a convergence on scientifically acceptable concepts. We call this process mutual projection. In the process of mutual projection, external representations were generated. Objects in the physical environment were represented in an imaginary world and these representations were associated with processes in the physical world. It is through this coupling that constituents of both the imaginary world and the physical world gain meaning. We further show that the external representations are rooted in sensory interaction and constitute a semi‐symbolic pictorial communication system, a sort of primitive ‘language’, which is developed as the practical work continues. The constituents of this pictorial communication system are used in the thought experiments taking place in association with the empirical experimentation. The results of this study provide a model of physics learning during hands‐on experimentation. 相似文献

基于构式语法理论的分析角度,文章分析了“最XX”的构式义“凸显XX所具属性的极性量级,第一”的形成与构式要素“最”的关系,“最”由“军功第一”之意逐渐泛化为表达某种属性的极性量级,这种意义一经形成就融入构式义之中。由于构式的语义规约或压制,使得进入构式中的“XX”激发出丰富的属性义、量度义或内涵义。 相似文献

The reinvigoration of popular nationalism in the USA and UK has largely been framed as counter to the cosmopolitan globalization associated with their elite universities over the past decade. Opposing these two sets of values may be too simplistic, however, given the cultural and political ties long institutionalized between elite universities and the nation. This article endeavors to highlight these entanglements—which were present before the election of Donald Trump or the fateful vote for Brexit—by drawing on interviews conducted with personnel at four elite research universities in these two countries from 2013 to 2014. In particular, this article focuses on the way these individuals invoked symbolic boundaries drawn along national lines as common sense, natural, and enduring, seeing their universities as embodying national characteristics, and as obliged to serve national interests. In providing ontological order to the world, the presence of this “banal” or “everyday” nationalism has arguably been central to the conceptualization and enactment of internationalization in these and other universities. These findings complicate discussions of elite universities as globalizing and unmooring from the nation-state framework, or otherwise working against the forces of nationalism. The article also raises new questions about divisions between different constituents of today’s globalizing academy. 相似文献

生物化学实验是“生物化学”教学中的重要组成部分,生化实验内容的选取既要与基础理论课内容相协调,也要不断发展,将新的科研成果融入其中。目前生化实验教学内容大多涵盖了蛋白质、核酸、维生素等部分内容,但是对于糖类知识模块较少涉及。糖类不仅是组成生命的三大类物质之一,对其生物活性的研究更是当前生命科学热点前沿之一。因此,借着当前教学革新的契机,有必要合理地选取一些成熟的糖生物学研究成果,将其运用到生化实验教学中去。通过探讨将唾液中抗流感相关糖链的检测应用到实验教学中去的可行性,使教学内容与生活实践相结合,不仅能够增强学生对糖链生物学功能的认识,更能使他们接触到科学前沿,增强对科学研究的兴趣。 相似文献

“The idea of nature” (general model of how things work) that is accepted in a society strongly influences that group’s social and technological progress. Currently, science education concentrates on analysis of stable pre-existing items to minimum constituents. This emphasis is consistent with an outlook that has been widely accepted since the late Renaissance—that characteristics of individuals depend exclusively on the properties of their microscopic components. Much of 19th and 20th century science seems compatible with that now-traditional outlook. But major parts of contemporary science (and fundamental technological problems) deal with open-system dynamic coherences that display novel and important characteristics. These important entities are not adequately treated by the presently-dominant idea of nature. In contrast, the notion of how the world works that contemporary science and current technological practice generate emphasizes synthesis and self-organization of far-from-equilibrium “dissipative structures.” Arguably, eventual success in meeting the severe technological and social challenges occasioned by increasing world population will require general diffusion and appreciation of that newer overall outlook. Chemistry educators have been important in developing and disseminating the earlier worldview—they can and should provide leadership for widespread adoption of the alternative idea of nature. 相似文献

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading. 相似文献
