Our Mother Tongue and Its Culture in English Learning

1.IntroductionAccording to the Sapir - Whorf Hypothesis, thelanguages we learn as a child (i.e., mother tongues)strongly influence the ways we think and view theworld. It is inevitable that in learning a second lan-guage transference happens and learners tend to per-ceive meanings in the second language (L2) from theirown culture. When speaking English, we may subcon-sciously transfer it into Chinese in mind. Differencesbetween two cultures affect the L2 learning in someway. There has been…

Parental work status and children's dietary consumption: Australian evidence

This study investigated associations between parents' work status and the dietary consumption patterns of Australian children, and whether such associations vary by parental education and usage of nonparental childcare. Data from the longitudinal study of Australian children at two waves from ages 2–3 years (n = 4601) to 4–5 years (n = 4381) were analysed. Logistic regression models were used to calculate odds ratios of children consuming (≥1 times/day) fruit and vegetables (FV), high fat foods (HFF), high sugar drinks (HSD), as well as evaluating the incidence of breakfast consumption. This was analysed against the employment status of parents including full‐time, part‐time and unemployed. Children of part‐time employed mothers were more likely to consume breakfast, and less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed fathers were less likely to consume FV and breakfast, and more likely to consume HSD compared with children of full‐time employed fathers. Children of nonemployed mothers were more likely to consume HFF, whilst those of nonemployed fathers were more likely to consume HSD and less likely to consume breakfast compared with other children. Amongst less‐educated parents, children of unemployed and part‐time employed parents were more likely to consume HFF and HSD and less likely to consume FV and breakfast compared with children of full‐time employed parents. Amongst highly educated parents, children of unemployed and part‐time employed mothers were less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed mothers who used family day care, day care centres and grandparent care were less likely to consume HSD and more likely to consume breakfast compared with children of full‐time employed mothers. Children of part‐time employed fathers and unemployed parents who used day care centres and grandparent care were less likely to consume FV and more likely to consume HFF compared with children of full‐time employed parents. Future studies should pursue a better understanding of the mechanisms for the adverse effects of parental work status on dietary consumption to develop and enhance specific interventions targeting these groups.     

“家”的守望者——巴金小说的思想性

巴金以一种极端的情绪宣泄心中的革命热情,表达对黑暗的控诉与对光明的呼唤。作品凝结着＂家＂的情结,他也成为了一个＂家＂的守望者。《家》继续了《红楼梦》的大家庭崩溃的主题,进一步揭示了＂家＂的破败,《憩园》和《寒夜》是《家》的续篇,老姚和汪文宣就是觉慧出走后的两个选择,都昭示新＂家＂的成立与夭折,他的小说表现了封建大家庭的崩溃,新型家庭的建立与夭折的历史。他像一个虔诚的教徒,翘首期盼着理想的社会秩序,守望着家的乐园。     

对跨文化交际教学中“母语文化失语”的反思

在外语教育中,我们只注重对目的语国家文化的学习,而学生在用外语表达自身文化的场合却出现了“母语文化失语”的现象。本文论述了外语教学跨文化交流学习中母语文化导入的重要性,并结合少数民族地区的现实,认为少数民族学生在学习外语的过程中,也应学习用外语表达自己民族的文化,培养多元文化思维能力,促进民族文化繁荣和民族团结。     

《宠儿》的艺术形象与审美价值

小说《宠儿》是美国黑人女作家托尼·莫里森的作品,它揭露了美国黑人在奴隶制被废除前的悲惨遭遇,以独特的主题反映了一个鬼魂复仇与寻求母爱的历程,表达了美国黑人深厚的母爱之情。     

外语学习中本族语的迁移与干扰

本文从迁移理论的实质出发，阐述了外语学习过程中，本族语(母语)的语言特征、模式或语法形式对外语学习所产生的影响——促进或干扰。提出在外语学习中，要根据迁移理论，利用母语正迁移的作用，排除母语负迁移的干扰，更快、更好、更有效在学习和掌握外语。     

一种优化K-means聚类的舌苔舌质分离方法

为了解决传统K-means聚类算法对舌图像中舌苔舌质分离效果不稳定的问题,提出了一种优化K-means聚类的舌苔舌质分离模型。模型综合RGB,HSV,L^*a^*b^* 3种颜色空间的特性,将单通道舌图像像素作为聚类样本集合,以一定的规则从集合中选取2个舌图像通道的像素作为聚类样本,并利用单通道舌图像分布直方图的峰值确定初始聚类中心点,最后通过聚类实现舌苔舌质分离。实验结果表明,选择用双通道舌图像作为聚类样本比用三通道或者单通道舌图像聚类效果更优,且提出的初始聚类中心点的确定方法相比于传统K-means聚类算法更准确、稳定地使舌苔舌质分离。所提方法可以很好地实现舌苔舌质分离,为中医舌诊客观化的研究提供了新的方法和思路,具有一定的实用价值。     

Restaurant Food Choices by Moms: An Exploratory Study

Restaurants are always seeking to better understand customer decisions. Mothers are of significance to restaurants as they have a direct influence on others, primarily children and spouses. This study focuses on what affects the restaurant food choices of “Moms” (a woman with at least one child 10 years or under). Three categories of factors were uncovered: externalities which occur outside of the restaurant environment, concurrencies which occur in the restaurant at the point of purchase, and confirming factors which cause an item to be confirmed or rejected after the purchase intention has formed. This article examines the externalities category.     

扩展卷积码生成矩阵的统一表述

针对在删除卷积码识别过程中缺乏对扩展卷积码先验认知的问题,提出了一种求解母码与扩展卷积码生成矩阵的统一表述方法。通过分析编码器输入输出关系的基本物理意义,先后以(n,1,m)、(n,k,m)作为母码,构建了其与扩展后编码器多项式系数的对应关系模型,归纳和证明了扩展卷积码生成矩阵的统一表述定理。验证结果表明:该定理能够对扩展卷积码生成矩阵实现快速计算,为遍历和重建删除卷积码的删除图样和母码生成矩阵提供方便。
