高二英语科组王春城
课本、报刊杂志中的成语、名言警句等俯首皆是,但学生写作文运用到文章中的甚少,即使运用也很难做到恰如其分。
为什么?
还是没有彻底“记死”的缘故。
要解决这个问题,方法很简单,每天花3-5分钟左右的时间记一条成语、一则名言警句即可。
可以写在后黑板的“积累专栏”上每日一换,可以在每天课前的3分钟让学生轮流讲解,也可让学生个人搜集,每天往笔记本上抄写,教师定期检查等等。
这样,一年就可记300多条成语、300多则名言警句,日积月累,终究会成为一笔不小的财富。
这些成语典故“贮藏”在学生脑中,自然会出口成章,写作时便会随心所欲地“提取”出来,使文章增色添辉。

其实,任何一门学科都离不开死记硬背,关键是记忆有技巧,“死记”之后会“活用”。
不记住那些基础知识,怎么会向高层次进军?
尤其是语文学科涉猎的范围很广,要真正提高学生的写作水平,单靠分析文章的写作技巧是远远不够的,必须从基础知识抓起,每天挤一点时间让学生“死记”名篇佳句、名言警句,以及丰富的词语、新颖的材料等。
这样,就会在有限的时间、空间里给学生的脑海里注入无限的内容。
日积月累,积少成多,从而收到水滴石穿,绳锯木断的功效。

一般说来,“教师”概念之形成经历了十分漫长的历史。
杨士勋(唐初学者,四门博士)《春秋谷梁传疏》曰:
“师者教人以不及,故谓师为师资也”。
这儿的“师资”,其实就是先秦而后历代对教师的别称之一。
《韩非子》也有云:
“今有不才之子……师长教之弗为变”其“师长”当然也指教师。
这儿的“师资”和“师长”可称为“教师”概念的雏形,但仍说不上是名副其实的“教师”,因为“教师”必须要有明确的传授知识的对象和本身明确的职责。

“教书先生”恐怕是市井百姓最为熟悉的一种称呼,从最初的门馆、私塾到晚清的学堂,“教书先生”那一行当怎么说也算是让国人景仰甚或敬畏的一种社会职业。
只是更早的“先生”概念并非源于教书,最初出现的“先生”一词也并非有传授知识那般的含义。
《孟子》中的“先生何为出此言也?
”;《论语》中的“有酒食,先生馔”;《国策》中的“先生坐,何至于此?
”等等,均指“先生”为父兄或有学问、有德行的长辈。
其实《国策》中本身就有“先生长者,有德之称”的说法。
可见“先生”之原意非真正的“教师”之意,倒是与当今“先生”的称呼更接近。
看来,“先生”之本源含义在于礼貌和尊称,并非具学问者的专称。
称“老师”为“先生”的记载,首见于《礼记?
曲礼》,有“从于先生,不越礼而与人言”,其中之“先生”意为“年长、资深之传授知识者”,与教师、老师之意基本一致。
