新时期大学英语教学中的文化教学

我国《大学英语教学大纲》（1999）明确指出,文化和语言有着密切的关系,一定的文化背景知识有助于促进语言应用能力的提高。大学英语教学目的之一就是提高语言应用能力和文化素质。鉴于此,笔者提出新时期大学英语教学中文化教学的几点建议。     

试谈英语教学中的文化导入

大学英语教学中,文化背景知识的渗透是很有必要的。本文分别从语言与文化的融合、文化导入有助于提高学生学习英语的兴趣、文化导入有助于提高学生的语言实际应用能力等作了阐述,通过尝试,收到好的效果。     

文化教学在大学英语教学中的应用研究

文化与语言有着密切的联系，一定的文化背景知识有助于促进语言应用能力的提高。然而在当前的大学英语教学中，文化教学尚未引起广大英语教师的普遍关注。因此，要理清语言与文化之间的关系，意识到文化教学的重要意义，在实际授课中强化文化教学。     

对文化在外语教学中的作用的探讨

我国高校英语专业高年级教学大纲和基础阶段教学大纲都相继规定加强学生社会文化意识,培养学生社会文化能力。笔者认为培养学生社会能力也是大学英语教学的趋势,因此,在大学英语教学中,把语言知识和文化背景知识相结合,在语言教学中导入相关的文化背景知识是非常重要的。这样,有助于加深学生对其语言现象的理解和领悟,从而培养学生的社会文化能力。     

论高职英语教学中的跨文化教育

当前，我国高职英语教学现状不容乐观，还存在着不少问题。为了解决这些问题，我们必须认识到语言与文化之间是相互联系的紧密关系。因此，我们应该在高职英语教学中实施跨文化教育，即从高职英语教学中实施跨文化教育的必要性入手，提出了我们应该采取一些积极有效的措施来切实实施高职英语教学中的跨文化教育工作，从而使得高职英语教学不仅是语言知识的传授，更是英语文化知识的传播，让高职学生能够具备良好的英语语言能力的同时，还能够具有较强的跨文化交际能力。     

浅议英语教学中的文化教学

完整的英语教育不应该割裂语言与文化之间的联系，英语教学不仅是语言知识的传授。而且更应包括文化知识的传播。本文阐述了在英语教学中加强文化教育的重要性及必要性以及在英语教学中的文化因素导入的方法与途径。     

中学外语教学中应渗透文化意识

语言是交际的符号，语言与文化密不可分。语言文化与交际是一个不可分割的统一体。学习语言的目的是为了交际，英语教学的目的是为了培养学生的交际能力，但真正的交际能力既包括语言能力，也包括社会文化能力。因此，英语教学既应该包括英语语言知识教学又应该包括语言文化知识教学。     

大学英语教学中的文化差异及对策研究

对于大学的英语教学来说,文化的差异直接造成了语言难理解和难学习的问题。所以大学的英语教学不单单传授的是语言知识,还应该传播西方的文化知识,把中西方的文化进行比较分析,不仅增加了学生学习文化的意识,而且可以达到学生真正理解掌握英语的目的,使他们可以更好的运用英语进行沟通交流。     

论大学英语教学中文化背景知识的渗透

英语教学不仅仅传授语言知识,还应该将文化知识渗透其中。适时适量的文化背景知识渗透在大学英语教学中发挥着重要作用.本文论述了文化背景知识渗透的方法、可行性、原则、重要性。目的在于通过文化背景知识渗透提高大学生对英语语言能力和跨文化交际能力的理解和运用     

大学英语教学中文化背景知识的导入

语言是文化的载体，是文化的一个重要组成部分；文化的传播离不开语言。两者之间相互影响，相互依存。我国的大学英语教学长期以来只注重语言本身，而忽视文化教学，造成学生跨文化交际能力低下。在国际化趋势日益明显的今天，大学英语教学应以交际需要为目的，以文化导入为手段，培养学生对中西方文化差异的敏感性，从而提高他们用英语交流信息的能力。     

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.

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。

An on-line scaling method for improving scalability of a database cluster

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.     

An improved R-tree based on childnode''s probability

R-Tree is a good structure for spatial searching. But in this indexing structure,either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different, if we make the subnode who has the most possibility be traveled first, the time cost will be decreased in most of the cases. In some case, the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).     

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.     

Integrating GIS Web services based on mediating architecture

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.
