句法-音系的交互与汉语韵律层级理论研究

语言之间具有共性特征,但也存在一定的差异。在语音表征方面,体现为个别音位的差异;而在音系表征方面,主要体现在音位组合模式和韵律模式的不同。韵律结构的系统研究,一直是西方音系学理论研究的课题之一。英汉两种语言在韵律模式上的区别主要体现在音节、音步和节奏模式等方面。通过对韵律音系学及韵律层级理论的回顾和考察,尤其是与目前汉语韵律层级结构理论框架的对比分析,笔者认为,韵律层级观可以用来解读句法对音系变化,尤其是韵律变化的制约作用。汉语韵律结构存在Nespor&Vogel(2007)所提出的韵律层级普遍规则,也符合其有关韵律严格分层的假说。当然,汉语韵律结构层次的分析也为韵律结构层次理论提供了强有力的支持性论据。

二语水平影响双语者创造性思维的认知机制:链式中介分析

以往研究虽验证了二语水平对创造性思维的积极影响,并确认了创造性思维领域的双语认知优势,然而对这种影响可能存在的复杂认知机制及影响路径缺少系统探究。为此,本研究通过语言背景问卷、双语切换问卷、认识灵活性测验和创造性思维测验,采用链式中介分析方法,以探究二语水平影响创造性思维的潜在认知机制。结果表明,在二语水平影响创造性思维的过程中,既有直接效应,也有间接效应。直接效应表现为"二语水平→创造性思维"的认知路径,间接效应则包括了"二语水平→双语切换能力→创造性思维""二语水平→认知灵活性→创造性思维"和"二语水平→双语切换能力→认知灵活性→创造性思维"三条认知路径。研究结果为创造性思维领域双语认知优势的有关理论解释提供了实验证据,也拓宽了外语教育的实践价值。

An Investigation Into Career Development Contexts of University Russian Language Teachers in China(1949-2019)From the Perspective of Ecological Theory

Although much research has been conducted on the interactions between the career development of foreign language teachers and their contexts around the world,a literature review reveals that there exists scanty research on the relationship between university Russian language teachers’career development and their contexts in China since 1949.Based on relevant studies on the career development of foreign language teachers and the ecological theory,this paper involves research on the impact that different ecological systems(micro-,meso-,macro-and exo-ones)have played in the career development of Russian language teachers in China.Participants are 10 Chinese Russian teachers of different ages from different universities in different parts of China.Via literature review,narration methods and semi-structured(in-depth)interviews with the help of NVivo,this research finds that Russian language teachers’career development results from multi-faceted interactions of the following contexts:ideology,Russian language educational policies and personal factors as well as college contexts.This paper concludes with some suggestions for improving Russian language teachers’career development in China.
