从内部词典的一种组织方式-激活扩散模型的角度出发,结合大学英语课堂教学实情,从三个方面即词汇知识维度、词汇学习关联度以及词汇复现率分析了影响学习者内部网络词典的构建的原因,并提出在对个词进行概念、词目和词位水平全面学习的基础上建立与其他词的联系有利于帮助学习者构建内部网络词典,促进产出性词汇的习得. 相似文献

基于实验班和对照班网络多媒体教学后限时口语测试语料中的产出性词汇,根据词汇广度和深度两个方面共7项指标分析网络多媒体教学对高职英语口语词汇产出能力的影响。结果显示,这种教学方式对产出性口语词汇的数量和质量都有显著促进作用。前者表现为口语词汇的产出速度,低频词汇、互不重复词汇及实词产出数量在教改模式实施之后的显著增加;后者则表现为学习者口语词汇的语义搭配及语用准确性在网络多媒体环境下的显著进步。 相似文献

运用实验研究的方法,探讨了基于语料库的自主学习模式对词汇产出能力以及词汇自主学习能力的影响。实验结果表明：基于语料库的自主学习模式比传统教学模式能更有效地扩大产出性词汇量,同时有助于学习者培养从语料中概括短语和句型的能力,增强词汇自主学习能力。 相似文献

产出性词汇运用能力往往不能与接受性词汇运用能力同步发展,这在英语学习过程中是一种普遍存在的现象.论文就产出性词汇运用与英语写作能力二者的关系进行了论述,同时对促进学习者产出性词汇运用能力的策略提出一些参考建议. 相似文献

词汇知识有不同维度,一般认为包括这几方面:词汇广度知识,词汇深度知识和接受性、产出性知识。本研究从产出性词汇出发,采用中国学习者英语口语语料库中英语专业的四、八级口语考试作为语料,探讨中国英语学习者口语词汇复杂性发展变化的趋势。研究结果表明,无论在不同学习阶段之间还是不同水平之间,测试者只有在第一和第三词频段呈现显著差异。 相似文献

本研究依据自主学习理论和词汇学习策略的研究成果,调查了85位大学一年级非英语专业学生的词汇学习笔记,研究英语学习者在大学学习阶段词汇自主学习的特点、词汇学习笔记对学习者词汇自主学习的优势作用和不足,认为：（1）大学英语学习者自主所学词汇主要集中在四级词汇水平,学习的词汇知识内容丰富,尤其特别依赖L1、关注词组搭配和丰富联想内化词汇来建立词汇网络;（2问汇笔记促进学习者词汇自主学习、发展学习策略。这一阶段学习者需要进一步发展元认知策略,以强化自主学习能力。期间,教师可以发挥更大的作用。 相似文献

以105名一年级大学新生为实验对象,进行了为期18个星期的词块教学法和常规教学法的对比性教学实验。结果显示：词块法可以促进高校非英语专业英语学习者接受性词汇和产出性词汇（自由产出性词汇）的增长;词块法和常规教学法对高校非英语专业英语学习者接受性词汇和产出性词汇的影响存在显著性差异,词块法对词汇知识的促进作用大于常规教学法。 相似文献

二语学习者的中介语存在石化现象,二语产出性词汇能力的石化是表现之一。语言输入在数量上和范围上的不足以及语言产出机会的缺乏不利于词汇能力的发展,高级词汇使用动机不强,词汇学习重量不重质和缺少相应课程等原因是造成二语学习者产出性词汇能力石化的主要原因。 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects.

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献
