北师大版高中数学必修五教学案

数列 1.1数列的概念 预习课本P3~6,思考并完成以下问题 (1)什么是数列?数列的项指什么? (2)数列的一般表示形式是什么? (3)按项数的多少,数列可分为哪两类? (4)数列的通项公式是什么?数列的通项公式与函数解析式有什么关系? [新知初探] 1.数列的概念 (1)定义:按一定次序排列的一列数叫作数列. (2)项:数列中的每一个数叫作这个数列的项. (3)数列的表示:数列的一般形式可以写成a1,a2,a3,…,a n…,简记为数列{a n}.数列的第1项a1,也称首项;a n是数列的第n项,也叫数列的通项. [点睛] (1)数列的定义中要把握两个关键词:“一定次序”与“一列数”.也就是说构成数列的元素是“数”,并且这些数是按照“一定次序”排列的,即确定的数在确定的位置. (2)项a n与序号n是不同的,数列的项是这个数列中的一个确定的数,而序号是指项在数列中的位次. (3){a n}与a n是不同概念:{a n}表示数列a1,a2,a3,…,a n,…;而a n表示数列{a n}中的第n 项. 2.数列的分类 项数有限的数列叫作有穷数列,项数无限的数列叫作无穷数列.

3.数列的通项公式 如果数列{a n }的第n 项a n 与n 之间的函数关系可以用一个式子表示成a n =f (n ),那么这个式子叫作数列{a n }的通项公式. [点睛] (1)数列的通项公式实际上是一个以正整数集N +或它的有限子集{1,2,3,…,n }为定义域的函数解析式. (2)同所有的函数关系不一定都有解析式一样,并不是所有的数列都有通项公式. 4.数列的表示方法 数列的表示方法一般有三种:列表法、图像法、解析法. [小试身手] 1.判断下列结论是否正确.(正确的打“√”,错误的打“×”) (1)同一数列的任意两项均不可能相同.( ) (2)数列-1,0,1与数列1,0,-1是同一个数列.( ) (3)数列中的每一项都与它的序号有关.( ) 答案:(1)× (2)× (3)√ 2.已知数列{a n }的通项公式为a n =1-(-1)n +1 2,则该数列的前4项依次为( ) A .1,0,1,0 B .0,1,0,1 C.12,0,1 2 ,0 D .2,0,2,0 解析:选B 把n =1,2,3,4分别代入a n =1-(-1)n + 12中,依次得到0,1,0,1. 3.已知数列{a n }中,a n =2n +1,那么a 2n =( ) A .2n +1 B .4n -1 C .4n +1 D .4n 解析:选C ∵a n =2n +1,∴a 2n =2(2n )+1=4n +1. 4.数列1,3,6,10,x,21,…中,x 的值是( ) A .12 B .13 C .15 D .16 解析:选C ∵3-1=2,6-3=3,10-6=4, ∴? ???? x -10=5,21-x =6,∴x =15. [典例] (1){0,1,2,3,4};(2)0,1,2,3;(3)0,1,2,3,4,…; (4)1,-1,1,-1,1,-1,…;(5)6,6,6,6,6. [解] (1)是集合,不是数列;

加油吧,少年,拼一次,无怨无悔! 高二数学必修五全套学案 §1.1.1 正弦定理 学习目标 1. 掌握正弦定理的内容; 2. 掌握正弦定理的证明方法; 3. 会运用正弦定理解斜三角形的两类基本问题. 学习过程 一、课前准备 试验:固定?ABC的边CB及∠B,使边AC绕着顶点C转动. 思考:∠C的大小与它的对边AB的长度之间有怎样的数量关系? 显然,边AB的长度随着其对角∠C的大小的增大而.能否用一个等式把这种关系精确地表示出来? 二、新课导学 ※学习探究 探究1:在初中,我们已学过如何解直角三角形,下面就首先来探讨直 角三角形中,角与边的等式关系. 如图,在Rt?ABC中,设BC=a, AC=b,AB=c, 根据锐角三角函数中正弦函数的定义,

有 sin a A c =,sin b B c =,又sin 1c C c ==, 从而在直角三角形ABC 中,sin sin sin a b c A B C == . ( 探究2:那么对于任意的三角形,以上关系式是否仍然成立? 可分为锐角三角形和钝角三角形两种情况: 当?ABC 是锐角三角形时,设边AB 上的高是CD ,根据任意角三角函数的定义, 有CD =sin sin a B b A =,则sin sin a b A B = , 同理可得sin sin c b C B = , 从而sin sin a b A B = sin c C =. 类似可推出,当?ABC 是钝角三角形时,以上关系式仍然成立.请你试试导. 新知:正弦定理 在一个三角形中,各边和它所对角的 的比相等,即 sin sin a b A B = sin c C =. 试试: (1)在ABC ?中,一定成立的等式是( ). A .sin sin a A b B = B .cos cos a A b B =

必修5《说木叶》导学案

语文必修五编号YW-BX--0301--09 《说“木叶”》导学案 编写人:阮景荷审核:刘凤时间:2013.4.6 班级:组别:姓名: 【学习目标】 1、积累诗词名句,理解古诗词语言富有暗示性的特点。 2、根据诗歌语言特点,领略诗歌的精妙之处,提高鉴赏古诗词的能力。 【学习重难点】 理解“木”与“树”、“木叶”与“树叶”、“落木”与“落叶”、“落木”与“木叶”的不同意味。【学习课时】二课时 【学法指导】: 1、朗读法 2、举一反三,迁移应用 第一学时 一、走近文本 1、导入新课: 学生共同背诵杜甫《登高》诗句“无边落木萧萧下,不尽长江滚滚来”;阐述个人对诗句的境界的感受。 杜甫的这两句诗历来以境界阔达闻名,在极其萧飒荒凉的景象中又充满着一种雄浑奔放的气势,重要的因素是“落木”传递出了这种意境。让我们一同走进林庚的《说“木叶”》,详细探究其中的奥妙。 二、走近作者 林庚先生是现代文学史上的杰出诗人,1933年出版了他的第一本自由体诗集《夜》。此后,林庚陆续出版了《春野与窗》《北平情歌》《冬眠曲及其他》《林庚诗逊等诗集和诗、论合编的《问路集》及诗性哲理随笔《空间的驰想》。学生们这样回忆自己的老师:80年代初,林庚先生给那时的师兄师姐上了一堂“告别课”。为了这一堂课,林先生整整准备了一两个月。半个多世纪的教学生涯,本来已经不用备课,可是先生说要讲出最高的水准来,必须一个字一个字地写好教案。讲完这节课,先生回家后大病一场。 人物评价: 燕园,少了一位良师;天堂,多了一位诗人。 ――载自北京大学校园网静希先生首先是一位诗人,是一位追求超越的诗人,超越平庸以达到精神的自由和美的极致。他有博大的胸怀和兼容的气度……他有童心,毫不世故;他对宇宙和人生有深邃的思考,所以他总能把握住自己人生的方向。——袁行霈学生活动:利用有关资料,对作者自然情况以及文学成就、创作主张进行自学了解 三、知识积累: 诵读课文,初步感知 (一)、基础自测(运用工具书自行解决识记字词,做好读书笔记) 1、注音: 万应锭()桅()杆接踵()而至寒砧()迢()远窸窣()沈佺.期()门闩 ( ) 心有余悸()姣姣()袅袅 ..()柳恽.() 2、阅读文本整体把握 思考:文题“说‘木叶’”表明了作者的论题,作者就此论题阐述了自己怎样的看法? 阅读文本,抓住关键语句。思考讨论并作出回答。 思路点拨:论题只是表明了论述的范围,并不是作者的观点体现。依据说理的思维格式—发现问题、分析问题,得出结论,再结合关键性的语句,可以很快的梳理出文章的脉络层次,便于理解作者的真实写作目的。

When we are stressed, depressed, 1 , or in a negative state of mind because we feel that "bad things" 2 happening to us, it is important to change those 3 thoughts into something positive. If we don't, we will only attract more "bad things." It is often very hard to think positive when so many things are negative, but I am ___4_ that someone, somewhere is worse off than you. We can choose to think 5__ by beginning with the smallest of steps. If you start with one small, positive thing and 6 it during the course of your day, you will begin to move into a more positive 7 : positive thoughts, feelings, opportunities. With practice, you will change your outlook and choose to be 8 , regardless of the events around you. Here are a few examples for you to 9 . Begin and end each day with a "Thank you for this wonderful day!" When you see the gas prices hiking, say "I am glad that I have a 10 in which to get around." If you are having health problems, be grateful for what does work: "I really do 11 my eyes that see, my ears that hear, my mouth that tastes, my legs that walk, my 12 that write. Write down what you're grateful for each day. When you're feeling really down, read what you 13 beforehand. This will help uplift your spirits. If you practice this 14 , you will find that your list will get longer and longer. The 15 to make it a moment of joyful peace is to move yourself into a positive thought and keep it there long enough. The more you practice, the happier you'll be. 1 A. upset B. healthy C. serious D. terrible 2 A. stop B. try C. keep D. avoid 3 A. relative B. negative C. sensitive D. positive 4 A. disappointed B. sure C. sad D. interested 5 A. carelessly B. stubbornly C. patiently D. differently 6 A. catch B. repeat C. speak D. sing 7 A. situation B. conclusion C. attention D. ambition 8 A. happy B. sad C. moved D. confused 9 A. take B. make C. set D. practice 10 A. ship B. car C. plane D. bike 11 A. perform B. put C. appreciate D. know 12 A. knees B. hands C. head D. arms 13 A. talked B. heard C. wrote D. saw 14 A. quickly B. specially C. slightly D. regularly
