语文课程的一个重要任务是培养语感。本文以语感为切入点,简略回顾了语文单独设科以来的语文教学实践历程,区分了“混沌化”和“科学化”这两种观念和做法,并指出语感培养应依靠语文教学的“混沌化”,而非“科学化”。 相似文献

试验选取三类不同熟期的春小麦品种(品系),在同一时间倒伏后,分期对比测定各品种(品系)倒伏后不同发育阶段的籽粒鲜重、干重,比较分析品种(品系)倒伏与未倒伏籽粒的灌浆特性及干物质积累变化规律。结果表明:倒伏对不同品种(品系)籽粒干物质积累动态变化的差异显著性影响不同,对同一品种(品系)的最大灌浆速率及到达最大灌浆速率的时间均存在着影响,最终对籽粒产量存在着不同程度的影响。 相似文献

对法国调节学派及其理论的分析 总被引:1,自引:0,他引:1
20世纪70年代在法国兴起的调节学派,对资本主义社会的发展形态做了一个新的理论阐述。调节学派作为西方马克思主义经济学学派,对社会科学各个领域的研究以及对欧洲许多国家的政策制定都有重大影响。本文介绍了调节学派的分析方法、主要理论观点,并做了相应的评述。 相似文献

一百年来,中国古代文学史的编写工作虽然取得了突出的成绩,但还存在着一些不足。要弥补这些不足,应注意四个方面的问题:一是保持多元的格局;二是开阔视野,拓展内容;三是体现当代精神,吸收新的研究成果;四是重积累,循序渐进。这样才能真正展示中国文学发展演变的真实面貌,揭示中国文学发展的内在规律。 相似文献

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6~84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P<0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P<0.01). (3) Soil iodine value was 0.11~2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution. 相似文献

To date, there have been few studies of mothers’ and fathers’ roles in caring for their adult children with intellectual disabilities. The present study investigated the care-giving roles of mother and father couples caring for their adult offspring with an intellectual disability, their psychological health, and the demands and satisfaction of their care-giving roles. Twelve Anglo-Australian middle-aged mother and father couples with an adult child with intellectual disability (mean age?=?24 years) participated in semi-structured interviews about their care-giving roles and completed a series of questionnaires pertaining to care-giving difficulties and satisfaction, hassles and uplifts, and general health. Findings indicated that an extremely high proportion of both mothers and fathers were in the clinical range for social dysfunction, anxiety/insomnia, and somatic complaints, although levels of depression were relatively low. The present study found that mothers undertake more daily care-giving tasks than fathers, but that the range of tasks is similar. Mothers also reported significantly more care-giving difficulties and satisfaction than fathers. Associations between measures differed somewhat for the two parent groups, indicating the need for further exploration of both mothers’ and fathers’ experiences. 相似文献

重译林语堂,是推动林语堂研究深入开展的迫切需要,对于国家文化发展战略的实施亦有着重要意义。林语堂英文原著的现有译本,不足之处甚多,但也自有其优长。根据翻译伦理对翻译行为的规范,汲取"筛选积淀重译论"的合理内核,将其具体化为"筛选———融汇———创新———超越",能为重译林语堂提供必要的理论指导,有助于林语堂英文原著汉语重译工作的积极开展,亦有助于文化的积累与发展。 相似文献
