基于英汉空间语义对比分析的英语空间介词习得实证研究

基于英汉空间语义对比分析结果，通过问卷调查与分析，研究英、汉空间识解异同对中国学生英语空间介词习得的影响，结果发现：（1）整体上学习者的语言水平对三类对应的习得有影响，但学习者的语言水平与他们的目标语空间识解能力发展没有同步对应关系。（2）在英语介词习得过程中，与汉语空间语义对应的空间语义最易习得，不对应最难，难度从对应、准对应到不对应逐渐上升。（3）不同语言水平学习者对同一空间场景的空间识解机制有差异。     

英汉介词比较谈

介词虽为小品词,但在英汉两种语言中却占有举足轻重的地位,尤其是英语介词。在英语中除了一些简单句如"Iamateach．er"等外,完全摒弃介词是构不成一个完美句子的。无论是英语介词还是汉语介词,都可表示多种关系。例如：英语的"at"可表示地点、时间、原因等多种关系;汉语的"在"可表示地点、方向和时间等关系。从语言学习的意义来看,对英汉两种语言的介词作一个比较研究是很有必要的。一、英汉介词特点比较（一）英语介词（thepreopition）现代英语介词绝大多数早已固定下来,如"at"for"in"Of"等。个另u介词是由其它词类演变而来的…     

基于CLEC语料库的大学英语四级常用写作词汇用法正误分析

在差错分析及中介语理论的基础上,文章将对中国英语学习者的写作词汇错误进行了讨论。研究中使用了“中国英语学习者语料库”（CLEC）,调查了134篇大学英语四级写作语料中的词汇错误。通过归类分析,发现词汇错误主要有词类错误、替代错误、省略型错误和冗余型错误,其原因既有母语干扰,又有对目的语规则不完整的学习。

学生习作中的语言错误与母语负迁移

本文就学习者写作中的语言错误进行分析与讨论。本文提出一个假设：学生习作中的语言错误与母语负迁移有一定的关系。为此，笔者对41名学生82篇四级模拟考试作文中的语言错误进行了统计分析。结果表明，学习者意识到表达障碍时，就会本能地寻求母语的表达方式．母语知识会不断地影响学习者对目的语的掌握，造成干扰。因此笔者建议在教学中应加强语言基本技能的训练，使学生充分了解英汉两种语言的句式、词汇的特点．尽量减少母语的负迁移。

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.     

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.     

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.     

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.     

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.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
