篇1：期中复习导航
1. 分式及分式方程：
解分式方程一定要有检验的步骤，因为有可能产生增根.分式方程的增根，满足分式方程去分母化成的整式方程，但使分式方程中分式的公分母为0.这一特点可以用来解有关的题目.
2. 反比例函数的性质：
（1）对于反比例函数y=（k≠0），当k>0时，函数图象的两个分支分别位于第一、三象限内，在每一个象限内，y随x的增大而减小；当k<0时，函数图象的两个分支分别位于第二、四象限内，在每一个象限内，y随x的增大而增大.
（2）比例系数k的几何意义：如图1，过双曲线上任一点P作PM⊥x轴于M，PN⊥y轴于N，则矩形PMON的面积S=PM·PN=｜y｜·｜x｜=｜xy｜=｜k｜.即过双曲线上任意一点作x轴、y轴的垂线段，它们与坐标轴围成矩形的面积均为｜k｜.
3. 勾股定理：直角三角形两直角边的平方和等于斜边的平方.
勾股定理的逆定理：若一个三角形有两条边的平方和等于第三边的平方，那么，这个三角形是直角三角形.
4. 数学思想方法：学习过程中要注意领悟以下思想方法.（1）类比的思想（分式与分数类比）；（2）转化的思想（分式方程转化为整式方程）；（3）分类讨论的思想（反比例函数图象的性质）；（4）数形结合思想（图形与数量关系的结合，勾股定理及其逆定理使“数”与“形”达到统一）；（5）数学建模思想（建立分式方程模型解决实际问题，求反比例函数的解析式一般利用待定系数法等）.
篇2：期中复习方法
为了达到这一目的，我们可以采用一种与此适应的复习方法，这种复习方法一般分为三步，所以可以叫做三步复习法．
第一步， 解决“面”的问题，也就是要全面地进行复习．
这一步的复习特点是：面要广，内容要细，复习时间要长.所谓“广”是指复习的范围，即不论是定义、定理、公式，还是例题和课后习题都要复习；所谓“细”是指复习的态度和深度，即要一课课、一节节地复习，每个定理、定义都要推敲，切不可认为内容已经学过而走马观花，应付了事，更不可为了图快而投机取巧；所谓“长”是指分配的时间，一般要占复习时间的三分之二左右，因为这一阶段的复习任务较重，不在时间上给予充分的保证，是很难完成任务达到预期目的的．
第二步，重点复习．
所谓重点复习是指利用一定的时间集中解决那些在第一步复习时发现的尚未掌握的遗留问题，另外，还要解决一些看起来不难领会，但还不能熟练运用的问题.要想解决这些问题，最好是有针对性地多练，自己可多找一些相关的习题，详细解答，弄清每一步的理由或依据，力求做到熟练掌握，尽快地解决问题.这一步的复习范围虽然比第一步要小，但问题集中，难度较大，因而一定要认真对待，切不可掉以轻心．
第三步，进行归纳总结工作．

PANDA
熊猫是我国的国宝，也是世界上濒临灭绝的动物品种之一。关于它的习性、寿命、现状等，你知道多少呢？
The panda is an endangered species (濒危物种)—there are only about 1,500 pandas left in the world. Pandas love to eat bamboo shoots (竹笋). They can live to about 30 years. Baby pandas are really small—only about the size and weight of a can of soda (苏打).
Most pandas live in bamboo forests in the mountains of western China. When people build more cities and farms, they destroy (破坏) pandas home. Also, pandas do not have babies very often. A panda usually has one baby, sometimes has two or three babies. So there are so few of them left in the world.
