初稿
As is shown above, a leader father is sitting in the chair with a seal grasping in the hand, and a lot of money beside him. He seriously said to his son that there is more to life than just money -it is power. Simple as the picture is, but a profound truth is reveled in the picture.
I surely disagree with father ’s philosophy. As a leader, he shouldn ’t use his power to make money. It is his duty to serve people wholeheartedly, just one person said “with great power comes great responsibility ”. If he stick to his philosophy. I believe that he will spend the rest of his life in prison. What’s worse, he could affect his son ’s philosophy, guiding him in the opposite direction , nothing can be done to reverse the trend itself. The only solution is to change father ’s philosophy. Because of many greedy officials in China, it is time to reverse the trend itself by establishing new policy. As Chinese always has been our confidence that we can change for the better and better.
In my opinion, there is more to to life than just money -it is happiness, nothing is important than happiness. We can live a colorful life in our spare time.

评分:
(一)感知内容情境激趣
1、教师话语导入:《滥竽充数》是一则流传千年的故事,大家一定很有兴趣再次来回味,谁能声情并茂地朗读或者复述课文?学生朗读与复述课文。
2、看课件《滥竽充数》的故事
(二)比较赏析领悟方法
1、讨论动画解说词比较课文内容更为详细的地方?
2、投影解说词文字:“……当时,有个叫南郭的人,家境贫寒,又没有一技之长,为了生活,壮着胆子冒充吹竽高手,要求参加齐宣王的竽乐队,齐宣王不加考核,就让他参加了竽乐队,从此……”以上片段与原文“有个南郭先生,从来不会吹竽,也混了进来。”做比较,说说有什么感受?
3、南郭为什么进竽乐队,以及怎样进的乐队?想象其他可能的起因和成因。(答案体现开放多样性)
4、讨论南郭进乐队,原文中哪一个动词概括得最确切?
5、教学小结:“混”字最为确切,围绕“中心词”“混”字,通过自由想象,把南郭进竽乐队的.原因(第一次心理活动)和过程讲述得很明确、丰满了。同学们围绕“滥竽充数”成因——“混”写片段,要求注重心理描写。
6、课堂独立写作,然后交流,评价激励。
(三)方法迁移,以点及面
1、师话语导入:找到中心词
确定扩写点,大家写出了南郭充数的多个原因,请大家以小组展开学习,思考原文中还可以找到哪些类似“混”的中心词,可以作为扩写点?
2、生小组读文讨论,教师引导。
3、小结:“装”字写出了“滥竽充数”的过程,“逃”字,它写出了“滥竽充数”的结果。板书:扩写点装逃
4、说词说句练习。说含有“装”字的词语,结合情境语言“画画”南郭吹竽的形象?
5、想象合奏时,齐宣王、吹竽者的“众生相”?想象南郭得到和别人一样多的俸禄时候,南郭此时的心理?(第二次心理活动)
6、说词说句练习。围绕“逃”来说几个成语?教师引导,学生描摹南郭逃跑的神情、动作形象,揣摩南郭逃跑的心理?(第三次心理活动)
7、选择“滥竽充数”的过程——“装”,或者“滥竽充数”的结果——“逃”为题,写一个片段。
8、交流片段“装”,交流片段“逃”各一、二例。教师学生相机点评。
(四)总结升华联接成篇
1、再次说说南郭人物的特点,成语“滥竽充数”的寓意。(答案体现开放)
2、同学对南郭献上几句劝告的忠言?生写作。过渡语:大家的“警世”暂时不作交流,留给大家把它点睛之笔,写在这次习作中。
师提出本次习作要求。学生连段成篇,前后照应全文写作。
本单元知识主要是教会学生名数之间的改写。包括单名数改单名数、单名数改复名数、复名数改单名数这些共3类。其中第一类又分为低级单位的单名数改成高级单位的单名数和高级单位的单名数改写成低级单位的单名数。如:350平方分米=( )平方米,3吨=( )千克。单名数改复名数也有两种,如:5.5平方千米=( )平方千米( )公顷,5050米=( )千米( )米。复名数改单名数与单名数改复名数类似。其实这些改写中,有同级单位不要改的,不同级的只要记住高级到低级乘进率,低级到高级除以进率就行了。
1、学法到写法的迁移。2、由说到写,说写结合,连段成篇。
