(一) 不知道从哪里听说的’“故瑀”这个典故,起初并不在意,但到后来,也就是不久前,这个词突然从我记忆的角落里走了出来,甚至还大大方方走到我脑海中央,挤走了“数理化”,蛮直却又理所当然地盘旋在那里,勾起了我大脑无数神经元的兴奋律动。当它们律动的是如此剧烈以至于我难以在继续构思我这篇作文时,我觉得,我唯有举手投降,用文字来安抚它们罢。 “瑀”字,有些辞书上说是“美玉”,但又有的说,是像“玉的石头
The development of kesterite photovoltaic solar cells has been hindered by large open-circuit voltage(Voc)deficit.Recently,Snzn deep point defect and associative defect cluster have been recognized as the main culprit for the Voc losses.Therefo
“读书之乐乐何如?绿满窗前草不除。”“读书之乐乐无穷,瑶琴一曲来熏风。”这是读《四时读书乐》时我记得的诗句。但我觉得用这样文绉绉的诗句来形容我的读书之乐总觉得不够贴切。 小时候不会认字,每天晚上都是妈妈绘声绘色的讲故事给我听。《乌鸦喝水》、《狼来了》、《三只羊》等等幼儿故事,我百听不厌。进入小学学会拼音认字后,我便开始自己读书。起先看的是《白雪公主》那样的童话故事,过了段时间竟和冰心先生一样,看
伟大的苏联作家高尔基说过“谁爱孩子,孩子就爱谁”,只有爱孩子的人才会教育孩子。当班主任的日日夜夜,我注重与孩子们的交流与沟通,和他们一起玩儿,一起聊,关心爱护他们,既是他们的严师,又是他们的朋友。在我眼里,每一个学生都是我的挚爱,我的自豪,我心中的希望。要想搞好教育必须首先播撒爱心,让爱成为师生情感的纽带。 一、倾注爱心,让学生成为你的知心朋友 接任一个新班后,我首先对每个学生进行全面了解,经
一、用笔的概念 书法,从某种角度上说,是用毛笔书写汉来创造意境表达人的某种气质、品格、情感的艺术。因此,书法之妙,全在用笔。蒙恬撰写了中国书法史上第一部论述毛笔的著作《笔经》。也就是说,早在两千多年前,先贤们就开始研究用笔的方法——笔法了。 笔法是书法的精髓。是书法艺术技法中最根本的基本功。用笔,可以说是用锋,也叫使锋、运锋和行锋,是完成字的点画时笔锋运动的规律。也可以概括地说,用锋就是执笔和
