“You can’t do all things better than anyone else. You can’t do all things at a time. You have to decide what comes first, and then do that.”

2.仔细观察反比例函数的解析式y=k/x,我们还可以把它写成什么形式？ 3.回忆我们学过的一次函数和正比例函数，我们是用什么方法求它们的解析式的？以此类推，我们也可以采用同样的方法来求反比例函数的解析式。 【课堂练习】 1.下列等式中y是x的反比例函数的是（） ①y=4x ②y/x=3 ③y=6x-1 ④xy=12 ⑤y=5/x+2 ⑥y=x/2 ⑦y=-√2/x ⑧y=-3/2x 2.已知y是x的反比例函数，当x=3时，y=7, (1)写出y与x的函数关系式；（2）当x=7时，y等于多少？

新人教版八年级下册数学导学案（全册） 第十六章 分式 16．1分式 16.1.1从分数到分式 一、 教学目标 1． 了解分式、有理式的概念. 2．理解分式有意义的条件，分式的值为零的条件；能熟练地求出分式有意义的条件，分式的值为零的条件. 二、重点、难点 1．重点：理解分式有意义的条件，分式的值为零的条件. 2．难点：能熟练地求出分式有意义的条件，分式的值为零的条件. 三、课堂引入 1．让学生填写P4[思考]，学生自己依次填出：7 10，a s ，33 200，s v . 2．学生看P3的问题：一艘轮船在静水中的最大航速为20千米/时，它沿江以最大航速顺流航行100千米所用实践，与以最大航速逆流航行60千米所用时间相等，江水的流速为多少？ 请同学们跟着教师一起设未知数，列方程. 设江水的流速为x 千米/时. 轮船顺流航行100千米所用的时间为v +20100小时，逆流航行60千米所用时间v -2060小时， 所以v +20100=v -2060. 3. 以上的式子v +20100，v -2060，a s ，s v ，有什么共同点？它们与分数有什么相同点和不 同点？ 五、例题讲解 P5例1. 当x 为何值时，分式有意义. [分析]已知分式有意义，就可以知道分式的分母不为零，进一步解 出字母x 的取值范围. [提问]如果题目为：当x 为何值时，分式无意义.你知道怎么解题吗？这样可以使学生一题二用，也可以让学生更全面地感受到分式及有关概念. (补充)例2. 当m 为何值时，分式的值为0？ （1） （2） (3) [分析] 分式的值为0时，必须同时．． 满足两个条件：○1分母不能为零；○2分子为零，这样求出的m 的解集中的公共部分，就是这类题目的解. [答案] （1）m=0 （2）m=2 （3）m=1 六、随堂练习 1．判断下列各式哪些是整式，哪些是分式？ 1-m m 3 2+-m m 112 +-m m

There be 句型的一般将来时。 【导学指导】 温故知新小组讨论设想未来世界的变化。 运用be going to谈论将来的计划和打算。 自主互助学习 知识剖析： 一般将来时态 构成: will / be going to +动词原形 1.用be going to do表示将来：主要意义，一是表示“意图”，即打算在最近的将来或将来进行某事。 Are you going to post that letter? I am going to book a ticket. 另一意义是表示“预见”，即现在已有迹象表明将要发生或即将发生某种情况。 It’s going to rain. 2.用will/ shall do表示将来： You will feel better after taking this medicine. 助动词will+动词原形 I will not lend the book to you. 变否定句直接在will后加not She will come to have class tomorrow. Will she come to have class tomorrow? 变一般疑问句，直接把will提到句首。 Yes,she will/ No.she won’t . 3. fewer 与less及more表数量的用法。 1）few（形容词）“几乎没有，很少的”，修饰可数名词。其比较级、最高级为规则变化：few－fewer－fewe st“a few”表示“一些”“few”带否定含义，“几乎没有”。 2）little（形容词）“很少的，几乎没有的”（“小的，幼小的”），修饰不可数名词。其比较级、最高级为不规则变化：little－less－least。例：There will be less pollution. “a little”表“一些”，“little”带否定含义，“几乎没有”。 3）many“许多”，修饰可数名词。much“许多”，修饰不可数名词。 比较级、最高级为不规则变化：many / much －more－most。 重点难点释义: 1.

第17章 分式 §17.1.1 分式的概念 导学目标： 1、经历实际问题的解决过程，从中认识分式，并能概括分式 2、使学生能正确地判断一个代数式是否是分式 3、能通过回忆分数的意义，类比地探索分式的意义及分式的值如某一特定情况的条件，渗透数学中的类比，分类等数学思想。 导学重点： 探索分式的意义及分式的值为某一特定情况的条件。 导学难点： 能通过回忆分数的意义，探索分式的意义。 导学过程： 一、做一做 （1）面积为2平方米的长方形一边长3米，则它的另一边长为_____米； （2）面积为S 平方米的长方形一边长a 米，则它的另一边长为________米； （3）一箱苹果售价p 元，总重m 千克，箱重n 千克，则每千克苹果的售价是___元； 二、概括： 形如B A (A 、B 是整式，且B 中含有字母，B ≠0)的式子，叫做分式.其中 A 叫做分 式的分子,B 叫做分式的分母. 整式和分式统称有理式, 即有理式 整式， 分式. 三、例题： 例1 下列各有理式中，哪些是整式？哪些是分式？ （1） x 1； （2）2x ； （3）y x xy +2； （4）33y x -. 解：属于整式的有：（2）、（4）；属于分式的有：（1）、（3）. 注意：在分式中，分母的值不能是零.如果分母的值是零，则分式没有意义.例如，在分式a S 中，a ≠0；在分式n m -9 中，m ≠n. 例2 当x 取什么值时，下列分式有意义？ （1）11－x ； （2）3 22 +-x x . 分析 要使分式有意义，必须且只须分母不等于零. 解 （1）分母1－x ≠0，即x ≠1. 所以，当x ≠1时，分式1 1 －x 有意义. （2）分母23+x ≠0，即x ≠-2 3 . 所以，当x ≠-23时，分式3 22 +-x x 有意义. 四、练习： P5习题17.1第3题（1）（3）
