从顺应论角度看英语被动句的选择

在言语交际中英语被动句并非主动句的简单语法替换形式 ,而是有着特定的语篇、语用及修辞用途。我们在交际中使用句子的时候 ,除了注意句子的结构正确外 ,还要注意所选择的句子在特定上下文或语境中的适合性。文章根据顺应理论从语言的顺应性出发 ,从三个方面解释对被动句的选择 ,即对被动句的选择要顺应语境因素、语义因素和语言结构因素     

农民工子女就学的制度性障碍与建议

农民工作为我国城镇化进程中出现的特殊群体,是社会不可忽视的重要组成部分.农民工在融入城市这一过程中权利与义务的对等发展逐渐引起整个社会的重视与关注,农民工子女就学问题作为其中之一更是社会关注的焦点.农民工子女就学问题中暴露出的种种问题归根结底是制度的变革与社会发展的不同步造成的.制度性障碍已经成为影响农民工子女就学的重要症结所在.     

Deme formation in gall-making aphidsAdelges japonicus (Homoptera: Adelgidae)

The deme formation hypothesis in herbivorous insects states that herbivores differentiate genetically into small demes, each specialized in the idiosyncratic traits of individual plants. We examined this hypothesis in gall-forming aphids,Adelges japonicus, by reciprocal transfers of aphids among three susceptible clones ofPicea jezoensis standing in proximity. Performance of aphids transferred to their natal clone was compared with that of aphids transferred to other novel clones. ANCOVA showed no significant donor (source of aphids) by receptor (recipient of aphids) interactions for both total aphid performance on the host tree over a life cycle and its three subdivisions(q ₁,q ₂ andq ₃). In addition, the total performance on the natal clone was lowest among those in the three clones, which was explicitly against the prediction from the local adaptation. In contrast, there were significant receptor effects onq ₁ (fecundity of gallicolae multiplied by survivorship of fundatrices while feeding on needles) andq ₃ (fecundity of fundatrices multiplied by survivorship of gallicolae before emergence from the galls), suggesting genetic differences in resistance among clones. The two-fold difference inq ₃ among clones was due to different gall size, which was highly correlated with the number of gallicolae that emerged from the gall. The two-fold difference inq ₁ seemed to be caused by different survivorship of larval fundatrices while feeding on needles.     

大学生学习适应性现状研究

以江苏工业学院和河海大学的1192名在校大学生作为被试,从学习环境、学习动机、学习能力、教育风格及身心健康五个维度对学习适应性问题进行了研究,结果显示:大学生的学习适应性总体上并不乐观,总体适应性水平的偏低;在具体维度上,大学生对学习环境的适应性最差,其余依次为教育风格、身心健康、学习动机、学习能力。男女生在学习动机、教育风格、学业成就上存在显著性差异,女生明显优于男生;在学习身心健康适应方面,男生优于女生,但差异不显著。     

交际文化的结构分析与教学体系建构

随着国际交流的日益加深，传统的纯语言知识和能力的教育已远远不能满足未来发展的需要，高素质即跨文化交际水平的培养将成为外语教学的最终目的。在这种情况下，就迫切需要有相应的教学模式作为理论指导，建构切实可行的教学体系来培养学生的目的语文化交际能力，这正是推动我国外语教学研究的一个强大动力。     

论高校扩招形势下加强教学质量管理

高校办学工作永恒的主题是教育教学质量。当前,在高校招生规模超常扩张的条件下,高校出现诸多教学质量保障条件的欠缺和不同程度的教学质量滑坡问题。如何加强教育教学质量的管理,建立有效的教育教学质量保证机制,确保教育教学质量的稳步提高,是当前各级教育行政部门和高校急需研究和解决的问题。     

析“归化”“异化”观

许多学者在翻译中对"归化"与"异化"的选择上存在争议,并提出许多不同观点,文中对有些观点提出了异议。文章认为,翻译应以交流为目的,译文要可接受、要传意,并要保持语言的鲜活。因此文中提出:语篇结构应追求归化,而内容应追求异化。     

A Study of Blockwise Wavelet Estimates Via Lower Bounds for a Spike Function

Abstract.  A blockwise shrinkage is a popular adaptive procedure for non-parametric series estimates. It possesses an impressive range of asymptotic properties, and there is a vast pool of blocks and shrinkage procedures used. Traditionally these estimates are studied via upper bounds on their risks. This article suggests the study of these adaptive estimates via non-asymptotic lower bounds established for a spike underlying function that plays a pivotal role in the wavelet and minimax statistics. While upper-bound inequalities help the statistician to find sufficient conditions for a desirable estimation, the non-asymptotic lower bounds yield necessary conditions and shed a new light on the popular method of adaptation. The suggested method complements and knits together two traditional techniques used in the analysis of adaptive estimates: a numerical study and an asymptotic minimax inference.     

高校专业设置和招生滞后的新制度经济学解释

高校专业设置和招生滞后分为朝阳专业和夕阳专业设置及其招生滞后，前是因为高校缺乏调整专业设置及其招生的自主权，后是因为路径依赖和高校既得利益集团的阻碍。解决对策之一在于扩大高校对朝阳专业设置和招生自主权，同时限制高校对夕阳专业设置和招生的自主权。
