妙玉论     
妙玉是曹雪芹精心塑造的最特殊的艺术形象,她栩栩如生,光彩照人,天生丽质,不输钗黛,更比黛玉孤傲。特殊的生活道路与社会环境,导致了她的冷僻,狂狷,孤芳自赏,好高过洁。气质美如兰,才华复比仙。她有青春爱的追求,但却没这种权利,只能将情事沤在心中憋得发疯.欲洁不能,欲空难空,僧不僧,俗不俗,男不男,女不女的,最后终于走向毁灭的深渊。  相似文献

高中生正处于身心发育的重要时期。一方面,他们闪现出许多的优点,如性情单纯,积极上进,思想开放,对新事物、新观念、新知识的接受能力强,敢想敢干,少有顾虑。但另一方面,由于缺乏经验,世界观、人生观、价值观还不成熟。如思维简单片面,感情容易激动,好走极端;自我中心,缺乏交流与合作精神;盲目自信,抗挫能力较差,常不能正确对待挫折等等。这些问题的出现,有偶然性,也有必然性,[第一段]  相似文献

丘逢甲自1895年内渡以后,为事业,亦为生计,主要从事兴学育才活动,余事才做诗人。清政府在对日战争中惨败,割地赔款,对国家而言,是深创巨痛。丘逢甲强烈地感受到,传统的科举制度不能再继续下去了,要救亡图存,必须振兴教育,提高国民素质。他主张多种形式办学,办师范,办女子学校,改进教育制度,培养新式人才。他主持的书院,也增加了新的教育内容。  相似文献

平凡也从容     
跋涉很长一段路程了,努力很长一段时间了,我们却依然平凡。是的,我们是平凡世界的芸芸众生。依然平凡的我们,没有“大腕”的显赫,没有“大款”的阔绰,但却不能因此而失却从容的心境。如石子一粒,仰高山之巍峨,但不自惭形秽。若小草一棵,慕白杨之伟岸,但不妄自菲薄。从容,是平凡者的坦然。从从容容,像一株无名的小花,不因牡丹的绚丽而锁苞,默默为春天增添一抹彩色;从从容容,像一棵山楂树,不因苹果的硕大而自枯,默默为金秋捧出几簇红果;从从容容,像一脉小溪,不因江河的渊博而干涸,默默地滋润一方土地……从容,是平凡者…  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

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-  相似文献

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-  相似文献

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  相似文献

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the  相似文献
