Chinese L2 Users’ Acquisition of the Simple Past Tense in English and Its Implications for Language Teaching

This paper sets out to examine some problems in Chinese L2 users’ acquisition of the simple past tense in English,for instance,L1 influence and overgeneralization,etc.This paper also represents an attempt to explore some relevant implications for language teaching,for example,the proposals to give due weight to negative evidence,to adopt Consciousness-raising,and so on.     

浅谈汉语负迁移对英语教学的影响

在现实中,英语教学会受到诸多因素的影响,汉语负迁移是其中非常重要的因素。加强汉语负迁移对英语教学影响的研究,具有极其重要的理论价值与现实价值。本文基于汉语负迁移的基本理论,对英语教学产生的影响进行了分析,从而得出应当怎样规避汉语负迁移环境下对英语教学的影响。     

特称否定命题不能换位的辩护

近年来,有逻辑学工作者对传统逻辑中的特称否定命题不能换位提出质疑。有的认为在赋予若干条件后SOP能换位为POS;有的认为通过欧拉图可以证明O命题是能够进行同质等值换位的;有的认为以全称命题为前提的换质位法推理中O命题是能够进行换位的。通过对他们的文章进行仔细的分析,发现他们的看法偏离了传统逻辑的研究对象、有悖于演绎推理的逻辑特性,存在误解特称量词"有"、"有的"的逻辑含义等问题。特称否定命题是不能换位的。     

网络围观“黑幕倾向”的负面效应及对策

作为一种基于互联网技术平台的新型政治参与方式,网络围观在技术手段上提高了网络民意在政府政策执行运作中的分量,然而网络广场对现实社会的揭示和质问总是呈现出一种“黑幕倾向”。从某种程度上讲揭露社会“黑幕”更能彰显网络围观的警示功能和监督功能,但另一方面网民热衷围观“黑幕”也容易招致负面的社会影响,分析网络围观“黑幕倾向”现象的成因并采取科学的应对措施将有助于消解中国的互联网治理困局。     

Negative Jealousy-Related Emotion Rumination as Consequences of Romantic Partner,Cross-Sex Friend,and Sibling Jealousy Expression

Negative jealousy-related emotion and rumination are examined as consequences of a close relational partner's jealousy expression. Specifically, relationship type (i.e., sibling relationships, cross-sex friendships, and dating partners) and three of Guerrero et al.'s (1995 Guerrero , L. K. , Andersen , P. A. , Jorgensen , P. F. , Spitzberg , B. H. , &; Eloy , S. V. ( 1995 ). Coping with the green-eyed monster: Conceptualizing and measuring communicative responses to romantic jealousy . Western Journal of Communication , 59 , 270 – 304 . [CSA] [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) forms of jealousy expression (i.e., distributive communication, integrative communication, and negative affect expression) are compared according to negative jealousy-related emotion and rumination following a hypothetical partner jealousy expression situation. Siblings and dating partners reported experiencing more intense negative emotion than cross-sex friends after partner jealousy expression. Further, participants reported ruminating more after their partners used distributive communication compared with integrative communication or negative affect expression to express jealousy. Emotional intensity did not vary according to type of jealousy expression and rumination did not vary with regard to relationship type. Practical and theoretical implications for the study of negative emotion, rumination, and partner jealousy expression are discussed.     

Departmental characteristics and the experience of secondary science teaching

This paper reports findings about the impact of departmental characteristics on secondary science teachers' work. It is drawn from a larger study, which also looked at ideological and material influences on practice. It focuses particularly on those aspects of the departmental environment which teachers themselves referred to frequently when discussing their work. These were: the managerial style of the department; the use made of schemes of work; the emphasis on the science disciplines as compared with 'science'; and the characteristics of pupils. It argues that such departmental characteristics are sometimes symbiotic, and that they are most subtly characterized in mainstream comprehensive schools. It also suggests that, while these influences do not necessarily lead to variation in the broad forms of pedagogy employed, they are perceived by teachers as significantly influencing their professional working environment, and the experience of teaching science.     

使用Q值提升技术的增益可调GSM低噪声放大器的设计

现代CMOS工艺的发展使得在CMOS工艺上设计射频IC前端成为可能。但在传统CMOS工艺集成的片上螺旋电感品质因数(Q)偏低,大大影响其性能。通过引入负电导实现螺旋电感Q值提升,并将其应用于共栅低噪声放大器的设计。     

Students’ Discrete Emotional Responses in the Classroom: Unraveling Relationships With Interest and Engagement

Recent instructional communication research reveals that the communication and emotional processes at play in the classroom can influence class-specific emotions experienced by students. Students’ enjoyment and pride were positively related to their emotional interest, while students’ enjoyment, hope, and pride were positively associated with their cognitive interest. While students’ anger and boredom were inversely related to their emotional interest, students who reported greater hopelessness and anger indicated decreases in cognitive interest. Students’ hope and pride were positively associated with their overall engagement behaviors. Anger, anxiety, shame, and boredom led students to report decreases in their engagement. Follow-up tests highlighted challenges in the assessment of specific emotional responses; exploratory factor analysis simplified the measurement of these variables and provided additional insight into expected relationships.

一种分析LC振荡器的简便方法

提出把LC振荡器等效成负阻振荡器的新观点，并以电容三点式振荡器为例，利用物理概念导出了该振荡器的振荡条件和振荡频率的准确公式，并将结果与相关讨论进行比较。由此推断：所有LC振荡器均可等效为负阻振荡器，从而可方便得到振荡条件和振荡频率。该方法的特点是物理概念清晰，数学过程简便。
