论中职学生说、读能力的培养

中职学校开设语文课程的主要任务是继续培养学生听、说、读、写的能力。其中，本人认为对中职学生而言，培养学生的“说”与“读”的能力最为重要。本人将从两个方面来探讨这一问题：一是提倡广泛阅读，培养良好习惯；二是把握语文教学特点，加强口语训练。     

中学作文发展探究

写作能力是中学语文的一项重要能力。作文不仅能反映一个学生的语言运用能力，更能反映其认识能力、审美能力、思想修养和文学艺术修养等。因此，作文能力的高低是衡量学生自身综合素质高下的一个重要方面。叶圣陶先生说：“学习国文应该认定两个目标，培养阅读能力，培养写作能力。培养能力的事必须继续不断地做下去，又必须改善学习的方法，提高学习效率，才会成功”。     

中学语文“说”的教学尝试

中学语文“说”的教学尝试鞠国洲叶圣陶先生说：“语文的目的是让学生掌握语言文字这种工具，培养他们的接受能力和发表能力。接受和发表，表现在口头是听（听人说）和说（自己说）……所以听、说、读、写、四项缺一不可，学生都得学好，这是生活的需要、工作的需要，也是...     

高中阶段英语听说能力的培养

《中学英语教学大纲》指出：“高中英语教学是在义务教育的基础上,巩固扩大学生的基础知识,发展听、说、读、写的基本技能,并在口头上和书面上初步运用英语进行交际的能力,侧重培养阅读能力,并使学生获得一定的自学能力,为继续学习运用英语切实打好基础。从《大纲》的要求不难看出,高中阶段英语教学重视学生听说能力的培养。国外学者里布斯和坦玻利就曾以英语为母语的成年人在听、说、读、写四个方面的交际活动作过调查。结果表明,“听”占言语交际活动总和的45％,“说”占30％,“读”占16％,而“写”占9％,由此不难看出听说能…     

从教学的本质谈高校英语教学改革

传统的英语教学难以使学生在听、说、读、写等方面全面发展。我国新修订的教学大纲明确提出要培养学生具有较强的阅读能力，一定的听、说、写、译能力，并能用英语“交流信息”，其实质是要培养学生的交际能力。本文以“语言是交际工具”为根本点，从英语教学的本质出发，阐发了对当前大学英语教学改革的几点思考。     

有效提高学生英语口语能力的策略

伴随着我国社会经济的不断发展，全球经济一体化的不断推进，作为一个国际性的语言种类，英语的口语表达能力愈来愈受到广大群众的关注。但是，在我国的英语教学当中，由于受到种种因素的影响，口语能力一直都是学生的一个薄弱部分，部分学生在“听”“写”两方面都比较好，但是“说”方面则比较差，甚至有些学生无法张口。可见，加强对学生英语口语表达能力的培养，是极为有必要的。鉴于此，文章将以大学为例，对影响学生英语口语能力提升的因素进行分析，并提出有效措施予以改善，以促进我国大学生英语口语表达能力的提高。     

浅谈民族预科生的数学“扶贫”教学

本文根据民族预科生的特点，提出对数学成绩差的学生要进行“扶贫”教学，并从四个方面进行数学：（1）要采用特殊的教学方法：（2）要加强基本知识的辅导；（3）要挖掘数学中美的因素，提高学生的数学审美能力；（4）要培养提高学生的数学语言能力，减少学习阻力。     

高职英语教学应着重培养学生的英语综合能力

在过去几年中，大学英语教学陷入了为改变“哑巴英语”和“聋子英语”现象而过分强调听、说能力培养的极端，从而在教学中对读、写、译等能力培养表现出不同程度的忽视，严重地影响了学生英语综合能力的提高，也在很大程度上影响了听说能力的拓展。文章旨在呼吁高职英语教学应突出其综合性、实用性、工具性的特点，着重培养学生的英语综合能力。     

浅谈高一学生英语书面表达能力的培养

书面表达能力是《高中英语教学大纲》规定的学生应具备的四大综合能力（听、说、读、写）之一。文章从句型训练、掌握各种体裁文章格式、练习与实践、纠错、阅读、背诵、书写几个方面介绍了高一学生书面表达能力的培养方法。     

加强对学生英语听力能力的培养

学习英语的关键是培养和提高“听、说、读、写”四种基本能力。在这四种能力的培养过程中，培养听的能力尤为重要，它是“说”“读”“写”的先决条件，只有听懂了，听的能力提高了，才会说，读和写。     

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.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.

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.
