元认知策略在英语专业听力教学中的应用

在外语教学和研究中,元认知策略是一项非常重要的认知策略,包括制定计划,监控学习过程,评估学习效果。它能提高学生的自主学习意识。本文主要探讨元认知策略的理论背景以及教师在英语专业听力教学中应用元认知策略,提高听力效果,促进英语专业学生听力理解能力。     

大学英语听力教学中元认知策略培训实证研究

元认知策略是指有效学习一门外语而采取的管理步骤,如计划、监控和评估。本研究通过问卷调查、大学英语四级测试卷以及写日记等定量和定性调查手段,探究了元认知策略使用与英语听力水平之间的关系以及元认知策略培训对听力理解能力和元认知策略使用意识的影响。研究发现:1)元认知策略使用与学生听力水平成正相关;2)元认知策略培训能提高学生听力理解能力;3)元认知策略培训能增加学生的元认知策略使用意识。     

元认知策略在高职高专大学英语听力教学中的应用

当前高职高专学生英语听力能力薄弱,学习的主动性、自觉性和自主性欠佳,通过在大学英语听力教学中融入元认知策略训练,培养学生的元认知意识,可以更加有效地开展听力学习,突破以往听力学习的瓶颈,提高英语听力水平。     

浅析元认知策略下的大学英语听力自主学习

听力一直是在英语学习中困扰学生的问题之一。由于受到课程设置、学时等限制,单靠课堂教学无法满足学生的听力学习需求。元认知策略可以帮助学习者有效地计划、监控和调整自己的学习过程和效果。引导学生在听力自主学习中运用元认知策略,不仅能提高学生的英语听力水平,同时也能提高学生的自主学习能力。     

元认知策略与英语专业听力教学

外语教师如何应对新形势下新的要求,从实际的教学条件出发,采取切实可行的措施提高听力教学质量是摆在我们面前的一个重要课题。元认知策略是重要的外语学习策略之一。文章通过元认知的概念、元认知策略与听力理解的关系,探讨了元认知策略在英语专业听力教学中的运用,即课前策略、课堂策略、课后策略的听力教学模式,有助于对学生听力自主学习能力的培养,增强他们的自主学习意识,改进学生的课外自主听力状况,提高听力教学质量,为大学英语专业听力教学更具有针对性和有效性提供参考。     

元认知策略与非英语专业研究生听力教学

针对非英语专业研究生英语听力教学现状，依据元认知理论，通过分析元认知及其主要内容、元认知策略的界定及分类，试图在元认知理论和非英语专业研究生听力教学之间搭建一个平台，把元认知和元认知策略引入非英语专业研究生听力教学实践，帮助学生培养元认知意识，切实提高听力水平。     

元认知策略:促进听力水平提高的有效策略

听力理解是第二语言学习中的一个重要环节。学生听力差的主要原因在于缺乏元认知水平。把元认知理论与实际教学相结合,探讨了如何培养学生听力理解中的元认知能力以及如何运用元认知策略(计划、监控和评估)来提高学生的听力水平。     

元认知策略应用于高职高专英语听力教学的实证研究

本研究以一所职业技术学院两个自然班的73名学生为调查对象,分析元认知策略使用与英语听力之间的关系。研究结果显示:(1)元认知策略的培训能有效提高高职高专学生的听力理解水平;(2)大多数学生的元认知意识在培训后都有显著提高;(3)听力能力强的学生使用元认知策略的频率高于听力能力弱的学生;(4)在听力理解能力的提高程度上,能力弱的学生提高的程度高于能力强的学生,这说明元认知策略的培训对听力能力弱的学生更具有潜力。     

元认知策略及其对大学英语听力教学的启示

元认知是认知主体对自身认知活动的认知.元认知能力直接影响着学生的自主学习能力,从而影响学生听力水平的高低.元认知策略对大学英语听力教学有着重要启示,在听力教学中应用元认知策略,可以提高学生自主练习听力的能力,增强听力的独立性和自觉性.从而最终使学生成为独立、自主、高效的学习者.     

非英语专业听力教学介入性研究——元认知视域

元认知策略和元认知意识为二语听力提供一个新的视角。近年来国内外很多研究得出结论,元认知策略和元认知意识对二语听力是有很大关联的。研究者采用了介入性研究方法,选择几个学生作为个案,对其进行元认知意识和元认知策略培训。研究结果表明,在恰当的语言策略的帮助下,元认知策略和元认知意识对听力一般的同学帮助很大,即能够在较短时间大幅度地提高他们的听力成绩。     

听力善学者与不善学者的听力理解策略的对比研究

听力理解策略是第二语言学习者在听英语材料时用于处理信息的重要技巧,在听力过程中,善学者与不善学者是否使用以及如何使用这些技巧可以有助于加强听力理解及信息的记忆。通过定量和定性研究,找寻两者的具体差异,进而指导学习者进行更为有效地听力学习。     

浅论英语听力理解失误的产生原因及解决方法

英语听力在英语学习中起着举足轻重的作用,它能够反映一个人的英语交流水平。但是很多英语学习者在听力理解方面存在各种各样的问题。解决听力理解问题,要从语音、听力与阅读的相关性、记忆、听者的情绪状态等几个影响英语听力理解的因素着手。     

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.     

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.     

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。

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。
