教材: 子集目的: 让学生初步了解子集的概念及其表示法,同时了解等集与真子集的有关概念.过程: 一 提出问题:现在开始研究集合与集合之间的关系.存在着两种关系:“包含”与“相等”两种关系. 二 “包含”关系—子集1. 实例: a={1,2,3} b={1,2,3,4,5} 引导观察. 结论: 对于两个集合a和b,如果集合a的任何一个元素都是集合b的元素,则说:集合a包含于集合b,或集合b包含集合a,记作aíb (或bêa)也说: 集合a是集合b的子集.2. 反之: 集合a不包含于集合b,或集合b不包含集合a,记作aëb (或bëa) 注意: í也可写成ì;ê也可写成é;í 也可写成ì;ê也可写成é。3. 规定: 空集是任何集合的子集 . φía 三 “相等”关系1. 实例:设 a={x|x2-1=0} b={-1,1} “元素相同”结论:对于两个集合a与b,如果集合a的任何一个元素都是集合b的元素,同时,集合b的任何一个元素都是集合a的元素,我们就说集合a等于集合b, 即: a=b2. ① 任何一个集合是它本身的子集。 aíaì¹② 真子集:如果aíb ,且a¹ b那就说集合a是集合b的真子集,记作a b③ 空集是任何非空集合的真子集。④ 如果 aíb, bíc ,那么 aíc 证明:设x是a的任一元素,则 xîa aíb, xîb 又 bíc xîc 从而 aíc 同样;如果 aíb, bíc ,那么 aíc⑤ 如果aíb 同时 bía 那么a=b 四 例题: p8 例一,例二 (略) 练习 p9 补充例题 《课课练》 课时2 p3五 小结:子集、真子集的概念,等集的概念及其符号 几个性质: aíaaíb, bíc þaícaíb bíaþ a=b 作业:p10 习题1.2 1,2,3 《课课练》课时中选择

1.2 第三教时 第10篇
教学过程:
一、复习检查:
简述老孙头的形象。
二、研习新课。
1.这节课我们来研读一下,作者还着力刻画了谁?他的思想品质如何?
郭全海。
分马前,他抓住时机教育群众,“分了东西可不能忘本啊”,分马时,他虽然在最前分马,却“随随便便”牵一头;当老孙头马跑了,他立即“翻身骑上”自己的骡马去追,累得“人马都气喘吁吁”。当他发现老王太太不中意自己的马时,他就主动提出跟老王太太换马,并又召集积极分子开会,启发大家要从长远利益出发跟老王太太换马。当老王太太换走了老田太太的马,郭全海又做老田太太思想工作,决定“开春马驹归你”,使矛盾圆满解决。
从这些方面可以看出,郭全海是一个忠于党,大公无私,毫不利已专门利人的人。
2.小结中心思想:
本文通过对分马换马的描写,反映了翻身农民分得胜利果实的喜悦心情。表现了先进农民大公无私的精神以及广大农民在党的领导下,思想觉悟迅速提高。
3.体会本文写人叙事详略得当的特点。
元茂屯参加分马的有三百来户人家,作者只写了其中十来个人,这十来个人,也安排得有详有略,主次分明。说说看,哪些人写得详;哪些人写得略?
详写:郭全海(主),老孙头(次)
略写:赵大嫂子,白大嫂子,老田夫妇,老王太太等。
为什么要这样安排?
小结:这样能突出中心思想,有略写配合,使得文章内容完整、全面,写出翻身农民的欢乐和他们觉悟的提高。同时,在各种人物对比映衬中,更能突出主要人物的性格特征。
