心理学家若干实验对学校教育的启示

“毛毛虫实验”。法国心理学专家曾经做过一个著名的“毛毛虫实验”：把许多毛毛虫放在一个花盆的边缘上，首尾相连，围成一圈，并在花盆周围不远处撒了一些毛毛虫比较爱吃的食物。毛毛虫开始一个跟着一个，绕着花盆的边缘一圈一圈地走，一小时过去了，一天过去了，又一天过去了，这些毛毛虫还是夜以继日地绕着花盆的边缘在转圈，     

过年随想

旧的一年过去了，新的一年又开始了。长久以来，人们的生活自然形成了以年为周期的周而复始的劳作。在农耕时代，春天播种，夏天管理，秋天收获，冬天则是农闲，正好盘点一年来的收成，祭祖拜神，休整疲惫的身心，期盼新的开始，所以，一般历法都把一年的起始放在了冬天。如今，我们许多人一年忙到头，已经对四季更替失去敏感，但习惯上还是把年作为周期来调整我们的生活和工作，所以年还     

兴趣是最好的教师

有一天，我刚到办公室。一个姓李的同学被他父亲带了进来。仔细一看，这位同学的双手是被捆绑起来的，脸上青一块、紫一块，显然是被“教训”了。一了解才知道，前一天上午，他父亲把他从网吧抓出来痛打了一顿，并进行了深刻的教育，他也保证再也不进网吧了。可当天晚上他又溜进了网吧，玩了一个通宵。     

灯盏窝，一串问号诉忧乐——湖南省郴州市煤矿安全隐患排查综述

在湖南煤监局对郴州市的煤矿安全生产隐患排查专项执法中，记者“随军”采访，跑了很远的路，吃了不少苦，流了许多汗，历时一周，宜章县与北湖区交界处的一座高山给记者留下了深刻印象，留下一串硕大的问号……     

一粒种子

初春时节，我爱随处走走，看看，到处可以感受到春天l一声炸响，一粒种子裂开了，经过一冬的束缚，也该活动活动筋骨。一棵幼芽拱开了泥土，搬开了岩石，钻出了地面!它看太阳四射光芒，它听小鸟叫“咕咕”。快乐心情势不可挡，可它不能忘记过去的了L即l敬踢认飞夕?多.;辙民间乌     

多余的知识

12岁那年，父亲要教我学游泳。隔壁住着一位体育老师，我去串门的时候，发现一本小册子，似乎叫《水上自救法》，便借回家阅读。没翻两页，父亲下班回来了，看见这本书，一把就夺过去，锁进抽屉，说：“儿子，我们游泳去！”约三、四天时间，我就能够“狗刨”了。经过一个暑假，我已能在水上玩得欢。后来的一天，父亲就将《水上自救法》还给我。我满怀兴趣地看了一遍，当夜，就按书中列举的一些险情做了几个惊恐的梦。6年前，我们当地一名富商回故乡投资，想在风景秀丽的山脚下建一所疗养院。他找到当地一位名医，请教此举的可行性。名医经…     

瞎凑热闹就是制造混乱

广场上，一人昂着头，惹得众人皆往天上看，大家都不知道发生什么事了，后来有人一打听，结果是第一个人流鼻血了。这是一个很旧的笑话，讽刺的是人有种盲目从众的心理。如今，它又有了新的现实版本。前些天，吹来一股“抢盐”风，惹得好些人按捺不住，纷纷凑起了热闹。现在风头一过，这些人又后悔不迭，接着上演了一场“退盐”潮。     

珍贵的礼物

尊重每一颗心灵，给一颗心灵尊严，是每一个人和每一个生命最珍贵的礼物。一座小城的乞丐们在圣诞节的前一天聚集在一起，他们在这座小城靠乞讨生活已经将近一年了，城里的居民给了他们一目三餐的生活，给了他们温暖，也给了他们许多难以忘怀的善良。在圣诞节即将到来时，他们决定选出一位施舍给他们最多、最善良也最使他们感动的人，然后全体乞丐要编织一只“善良天使”的花环，把它作为圣诞礼物，送给大家公认的最善良的他（她）。     

第一场雪

昨天，下了一夜的雪。这是今年的第一场雪。屋外白茫茫的一片，地上像是铺上了一层厚厚的、软软的地毯，脚踩上去发出“咯吱咯吱”的响声；松树穿上了一层又一层雪白的棉袄，像一座座白塔；公共汽车顶上都落满了雪，仿佛抹了白色的奶油似的……这场雪下得真好啊!     

阳光下的政府

某地一位农民想办一个养鸡场，前前后后盖了270多个公章，跑了两年多，等手续办下来，市场行情已经发生了变化；一名外商打算在某地投资，一年多过去了项目仍在审批过程中，看好的投资收益成了“黄花菜”，外商在当地的招商会上失声痛哭……     

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.     

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     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

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
