加强教学反思 促进教师成长

当前，教学改革普遍认同的两个观点是：教师是教学改革的关键；教学改革最终发生在课堂上。因此，加强教师培训、促进教师成长，改革课堂教学、让课堂教学充满生机与活力就成为教学改革与发展的主题。教学反思为教师的成长提供了一条极为重要的途径。其实，教师的成长过程就是在课堂教学实践中不断总结经验、捕捉问题、反思实践的过程。当前，教学改革普遍认同的两个观点是：教师是教学改革的关键；教学改革最终发生在课堂上。因此，加强教师培训、促进教师成长，改革课堂教学、让课堂教学充满生机与活力就成为教学改革与发展的主题。教学反思为教师的成长提供了一条极为重要的途径。其实，教师的成长过程就是在课堂教学实践中不断总结经验、捕捉问题、反思实践的过程。

对课堂教学风格的再认识

课堂教学风格是教师在长期的课堂教学实践中逐步形成，并通过较完善的课堂教学活动在课堂教学的技能与技巧、方式与方法及作风等方面稳定地、综合地表现出来的课堂教学特点与风貌，它体现着教师个人一贯的教学心理品质，是教师劳动个性化的最高境界。本文从课堂教学风格的基本要素、类型、形成以及对教学工作的影响等方面作了：系统的分析。     

定性与定量相结合,科学地进行课堂教学评价

课堂教学是教学工作的主渠道，课堂教学的质量直接影响着教学质量。因此，各级各类学校均对教师的课堂教学给予足够的重视。“优质课评选”、“青年教师课堂教学优秀奖”等活动频繁地出现在大学校园，也是学校改革中引入竞争机制、优化环境、培养和选拔优秀人才的良好举措。科学地评价课堂教学，可以评价教学质量，促进课程建设，促进教学管理的改进；可以促进教与学双方的提高和进步，为教师提供教学反馈信息，促使教师教学观念和教学方法的改革，增加教师对教学工作的投入，迅速地提高教学质量，如何科学地进行课堂教学评价，自然成为教学…     

课堂教学中教师情绪的自我调控

教师的情绪是否饱满，奠定了课堂教学是否成功的基调。一节高效的课堂，教师必须要有平和的心境，有爱护、包容学生的态度以及稳妥处理生成的睿智。但由于环境、事物的影响，教育对象的复杂多变，难免给教师带来惊慌、烦躁、抑郁、兴奋等种种消极情绪反应。如果把这种消极情绪带入课堂，将严重影响课堂教学的效果，降低课堂教学质量。因此教师需要克服消极情绪，培养自我调控能力。

课堂教学的两个核心要素是教师和学生，教师决定着课堂教学质量、学生决定着课堂教学效果．本文探讨如何提高课堂教学质量以取得较好的教学效果。     

新课改中教师如何体现主导作用

一、教师的主导体现在创造良好的课堂氛围上 学生主体地位最佳表现就是充分参与到教学中来；教师主导作用的充分发挥就在于极大地调动学生参与课堂的教学，因此教师主导作用的首要内容就是要在课堂教学中，构建和谐、民主的课堂教学氛围，师生互动的课堂情境，使学生真正参与到课堂教学中来，树立学习探研的氛围。教师在课堂教学中要引导学生信任老师，消除学生对老师的紧张情绪，敢于想象、敢于发表自己对事物的看法，     

有效课堂教学管理策略刍议

课堂作为教学的基本场所，其蕴藏着复杂多变的结构、情境与互动。有效的课堂教学不在于教师教了多少，而在于学生学到多少。要实现有效课堂教学，就需要有效的课堂教学管理。课堂教学管理主要的目的是协调、控制、整合各种教学因素及其关系，使之形成一个有序的整体，从而保证课堂教学活动的顺利进行。有效课堂教学管理是提高教师课堂教学效率与育人质量的重要保证。     

尊重教学实际，提高课堂教学的有效性

课程改革活跃了我们的课堂，新的理念、新的课标、新的教材、新的教法，使教师充满激情，学生充满活力，课堂教学变得更为精彩。有些教师过于追求课堂教学改革的形式，而忽略了数学教学的基本出发点，不尊重课堂教学的实际，失去了课堂教学的“有效性”。本文将从尊重教学条件、尊重教学内容、尊重学生状态、尊重课堂活动四个方面，谈谈如何提高课堂教学的有效性。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.
