文道结合是语文教学的基本指导方针。《全日制中学语文教学大纲》明确规定:“语文教学必须以马克思主义为指导”“在语文教学过程中,要开拓学生的视野,发展学生的智力,培养学生的社会主义道德情操、健康高尚的审美观和爱国主义精神,提高社会主义觉悟”。《大纲》强调了语文教学的思想教育作用。然而,近些年来,由于资产阶级自由化思潮的泛滥和片面追求升学率倾向的影响,语文教学曾一度偏离了这一方  相似文献

中学生文学社团是语文课外活动的一种好形式.由于它有广阔的活动空间,丰富的活动内容,所以对中学生来说具有强大的吸引力.它能开阔学生的视野,促进语文教学质量的提高,对于未来人才的培养也是具有积极的意义的.中国现代史上最先在学校出现的文学社团是浙江新潮社.1919年10月10日,杭州甲种工业专门学校学生夏衍(沈端先)等联络杭州一中的几位同学创办了《双十》半月刊,出版两期后,他们又吸收了浙江师范的部分学生组成文学社团“浙江新潮社”,并将《双十》半月刊改为《新浙江潮》周刊.他们在周刊上发表文章,探讨思想、学术和当…  相似文献

Immortalized F2 population of rice (Oryza sativa L.) was developed by randomly mating F1 among recombinant inbred (RI) lines derived from (Zhenshan 97B ( Minghui 63), which allowed replications within and across environments. QTL (quantitative trait loci) mapping analysis on kilo-grain weight of immortalized F2 population was performed by using newly developed software for QTL mapping, QTLMapper 2.0. Eleven distinctly digenic epistatic loci included a total of 15 QTL were located on eight chromosomes. QTL main effects of additive, dominance, and additive ( additive, additive ( dominance, and dominance ( dominance interactions were estimated. Interaction effects between QTL main effects and environments (QE) were predicted. Less than 40% of single effects, most of which were additive effects, for identified QTL were significant at 5% level. The directional difference for QTL main effects suggested that these QTL were distributed in parents in the repulsion phase. This should make it feasible to improve kilo-grain weight of both parents by selecting appropriate new recombinants. Only few of the QE interaction effects were significant. Application prospect for QTL mapping achievements in genetic breeding was discussed.  相似文献
