    人教部编版语文八年级下册《庄子》二则教案

    庄子是战国时期著名的思想家、哲学家和文学家。他是道家学派主要代表人物之一,他继承并发展了老子的思想,与老子并称“老庄”。《庄子》又名《南华经》,是道家经典著作之一。《庄子》主要反映了庄子的批判哲学、美学等,其内容丰富,博大精深,涉及哲学、人生、政治、社会、艺术、宇宙生成论等诸多方面。《庄子》是一部文学的典范著作。“道”是庄子思想的核心,“逍遥游”是庄子不满黑暗现实的羁绊而提出的一种生活方式与社会理想。庄子主张超然物外,绝对自由地生活在世界上,他认为生命的意义不在于庸俗地活着,而在于逍遥地神游,这些精神的遨游是绝对自由的,在庄子看来,自然是一种超凡脱俗的状态,一种妙不可言的境界。庄子的“逍遥游”是一种感性的生活方式,他告诉我们要去追求功利之外独立的生命价值,追求人生的真实自我。从当下来看,庄子追求的逍遥境界,是无法实现的主观唯心主义幻想,是一种乌托邦式的美好的臆想。

    初中数学七年级上册第一章有理数加法第二课时

    一、旧知回顾1、有理数的加法法则:(1)同号两数相加,取相同的符号,并把绝对值相加。(2)绝对值不等的异号两数相加,取绝对值较大的加数的符号,并用较大的绝对值减去较小的绝对值。(3)互为相反数的两数相加得零。(4)一个数与零相加,仍得这个数。注意:一个有理数由符号和绝对值两部分组成,进行加法运算时,应注意确定和的符号和绝对值.

    北师大初中数学八年级上册二次根式及其化简1教案

    方法总结:(1)若被开方数中含有负因数,则应先化成正因数,如(3)题.(2)将二次根式尽量化简,使被开方数(式)中不含能开得尽方的因数(因式),即化为最简二次根式(后面学到).探究点三:最简二次根式在二次根式8a,c9,a2+b2,a2中,最简二次根式共有()A.1个 B.2个C.3个 D.4个解析:8a中有因数4;c9中有分母9;a3中有因式a2.故最简二次根式只有a2+b2.故选A.方法总结:只需检验被开方数是否还有分母,是否还有能开得尽方的因数或因式.三、板书设计二次根式定义形如a(a≥0)的式子有意义的条件:a≥0性质:(a)2=a(a≥0),a2=a(a≥0)最简二次根式本节经历从具体实例到一般规律的探究过程,运用类比的方法,得出实数运算律和运算法则,使学生清楚新旧知识的区别和联系,加深学生对运算法则的理解,能否根据问题的特点,选择合理、简便的算法,能否确认结果的合理性等等.

    属于此类问题一般有以下三种情况①具体数字,此时化简的条件已暗中给定,②恒为非负值或根据题中的隐含条件,如(1)小题。③给出明确的条件,如(2)小题。第二类,需讨论后再化简。当题目中给定的条件不能判定绝对值符号内代数式值的符号时,则需讨论后化简,如(4)小题。例3.已知a+b=-6,ab=5,求 的值。解:∵ab=5>0,∴a,b同号,又∵a+b=-6<0,∴a<0,b<0∴ .说明:此题中的隐含条件a<0,b<0不能忽视。否则会出现错误。例4.化简: 解:原式=|x-6|-|1+2x|+|x+5|令x-6=0,得x=6,令1+2x=0,得 ,令x+5=0,得x=-5.这样x=6, ,x=-5,把数轴分成四段(四个区间)在这五段里分别讨论如下:当x≥6时,原式=(x-6)-(1+2x)+(x+5)=-2.当 时,原式=-(x-6)-(1+2x)+(x+5)=-2x+10.当 时,原式=-(x-6)-[-(1+2x)]+(x+5)=2x+12.当x<-5时,原式=-(x-6)+(1+2x)-(x+5)=2.说明:利用公式 ,如果绝对值符号里面的代数式的值的符号无法决定,则需要讨论。方法是:令每一个绝对值内的代数式为零,求出对应的“零点”,再用这些“零点”把数轴分成若干个区间,再在每个区间内进行化简。

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。

And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B.
