我国古代的读书人,从上学之日起,就日诵不辍,一般在几年内就能识记几千个汉字,熟记几百篇文章,写出的诗文也是字斟句酌,琅琅上口,成为满腹经纶的文人。为什么在现代化教学的今天,我们念了十几年书的高中毕业生甚至大学生,竟提起作文就头疼,写不出像样的文章呢?吕叔湘先生早在1978年就尖锐地提出:“中小学语文教学效果差,中学语文毕业生语文水平低,……十几年上课总时数是9160课时,语文是2749课时,恰好是30%,十年的时间,二千七百多课时,用来学本国语文,却是大多数不过关,岂非咄咄怪事!”寻根究底,其主要原因就是腹中无物。特别是写议论文,初中水平以上的学生都知道议论文的“三要素”是论点、论据、论证,也通晓议论文的基本结构:提出问题――分析问题――解决问题,但真正动起笔来就犯难了。知道“是这样”,就是讲不出“为什么”。根本原因还是无“米”下“锅”。于是便翻开作文集锦之类的书大段抄起来,抄人家的名言警句,抄人家的事例,不参考作文书就很难写出像样的文章。所以,词汇贫乏、内容空洞、千篇一律便成了中学生作文的通病。要解决这个问题,不能单在布局谋篇等写作技方面下功夫,必须认识到“死记硬背”的重要性,让学生积累足够的“米”。答:要卖出6部汽车。

观察内容的选择,我本着先静后动,由近及远的原则,有目的、有计划的先安排与幼儿生活接近的,能理解的观察内容。随机观察也是不可少的,是相当有趣的,如蜻蜓、蚯蚓、毛毛虫等,孩子一边观察,一边提问,兴趣很浓。我提供的观察对象,注意形象逼真,色彩鲜明,大小适中,引导幼儿多角度多层面地进行观察,保证每个幼儿看得到,看得清。看得清才能说得正确。在观察过程中指导。我注意帮助幼儿学习正确的观察方法,即按顺序观察和抓住事物的不同特征重点观察,观察与说话相结合,在观察中积累词汇,理解词汇,如一次我抓住时机,引导幼儿观察雷雨,雷雨前天空急剧变化,乌云密布,我问幼儿乌云是什么样子的,有的孩子说:乌云像大海的波浪。有的孩子说“乌云跑得飞快。”我加以肯定说“这是乌云滚滚。”当幼儿看到闪电时,我告诉他“这叫电光闪闪。”接着幼儿听到雷声惊叫起来,我抓住时机说:“这就是雷声隆隆。”一会儿下起了大雨,我问:“雨下得怎样?”幼儿说大极了,我就舀一盆水往下一倒,作比较观察,让幼儿掌握“倾盆大雨”这个词。雨后,我又带幼儿观察晴朗的天空,朗诵自编的一首儿歌:“蓝天高,白云飘,鸟儿飞,树儿摇,太阳公公咪咪笑。”这样抓住特征见景生情,幼儿不仅印象深刻,对雷雨前后气象变化的词语学得快,记得牢,而且会应用。我还在观察的基础上,引导幼儿联想,让他们与以往学的词语、生活经验联系起来,在发展想象力中发展语言。如啄木鸟的嘴是长长的,尖尖的,硬硬的,像医生用的手术刀―样,给大树开刀治病。通过联想,幼儿能够生动形象地描述观察对象。
