关于丢番图方程x2+by=cz

设s,t满足gcd(s,t)=1,s>t的正整数,a=2st,b=s~2-t~2,c=s~2+t~2。证明了:若c为素数幂且满足下列条件之一:(1)b有因子b_1≡±5(mod8),(2)b≡-1(mod8),(3)5|c。则不定方程x~2+b~y=c~z仅有一组正整数解(x,y,z)=a,2,2。     

阅读教学中学生英语写作能力的培养

阅读与写作关系密切 ,阅读能力和写作水平是相辅相成的。大量的阅读不仅丰富写作的内容 ,而且刺激写作兴趣 ;从语篇入手 ,给精读课文加边注、列提纲、写概要的方法 ,不仅可以培养学生独立思考、逻辑分析、语言及内容的组织和概括能力 ,而且可以使学生加深对文章的理解 ,养成良好的阅读习惯。     

衔接 连贯与阅读理解

衔接是语篇特征的重要内容.尽管语义上连贯的语篇可以没有形式上的衔接纽带,但在大多数自然出现的语篇中是存在衔接纽带的,这些纽带不仅会增强语篇的连贯性,而且对阅读理解有着很大的帮助作用.分析衔接与阅读的关系以及如何应用照应、替代、省略、连接和词汇衔接纽带促进并加深对语篇的理解.     

Determinants of housing quality: A comparison of white,African-American,and Hispanic single-parent women

This study examines housing quality among three groups of single-parent women: white, African-American, and Hispanic. Three indicators of housing quality—crowding, affordability, and satisfaction—are used to discover the extent to which these groups experience housing problems. This study also explores differences and similarities in the factors that precipitate problems in housing quality for these three groups of single parents. Findings suggest important differences and similarities in the nature of housing quality problems among white, African-American, and Hispanic single-parent women. The specified variables explained about 20% of the variance in crowding, housing affordability, and housing satisfaction. On measures of objective and subjective housing quality, white single mothers are better housed than their African-American or Hispanic counterparts. Hispanic single mothers have the largest housing cost burden and average more persons per household than the other groups. African-Americans are twice as likely as either group to live in low-quality housing and reported the lowest average satisfaction with their housing. Her research interests include housing and neighborhood assessment and women and public policy issues. She has recently published articles inUrban Affairs Quarterly andHousing and Society on housing and neighborhood assessment criteria among black urban households and the housing cost burden of various groups of female-headed households. She received her Ph.D. from Ohio State University. Her research interests include the housing adjustment behavior of women and public policy. She has recently completed her thesis on the role of noncustodial parents in determining the quality of life of their children. She is also the recipient of the Tessie Agan Award for research excellence from the American Association of Housing Educators for a paper titled “Unterstanding Constraints and Residential Satisfaction among Low-Income Single-Parent Families.”

汉语词语构成的音节因素和节奏语感的培养

汉语音节和构调、词语搭配存在相关性。语素的音节特点、双音节化倾向、四字格成语的大量存在和音节式的缩略词是音节和构词相关性的重要方面。汉语的音节特点也影响到单、双音节词语的相互搭配以及某些虚词的使用。汉语学习者的语言错误有不少是由不了解词语构成在音节和语音节律方面的制约因素而引起的。从语言交际技能的角度看,准确把握节奏规律的实质就是建立准确、健全的节奏语感,而加强诵读教学便是有效方法之一。     

论刘勰文学批评的“文本”精神

刘勰的文学批评有别于先秦两汉时期的“以德为本”的文学批评。贯穿刘勰文学批评始终的是“以文为本”的精神,“文”是刘勰文学批评理论的核心,也是刘勰文学批评方法论依据。刘勰文学批评中的“文本”精神是我国文学批评走向自觉的重要标志。     

论拉伦茨氏裁判方法的实质

使用传统的判案理论系统分析了拉伦茨氏的方法论体系。指出，拉伦茨氏方法论的基础是欧洲传统“名判”逻辑，其设定目标乃个案公决。拉伦茨氏强调了法官“续造法”的权力。所续造的“法”不是条法，而是曾经自主运用诸条法的模式，它理应有“现行法”的拘束力。“条法库”的缺漏由审判员以法律运用技术补足。诸准则之不谐或与宪法条法的不谐需赖“法益衡量”调谐。分析结论是，拉伦茨氏片面突出法官的自主地位，其方法论在本质上是现代法治社会一种尚需调制的折衷系统。
