A One day, a fisherman caught a golden fish.“People let me go,” the golden fish said.“I will give you whatever you want.”

“Thank you, but I don’t want anything,” the fisherman said.He put the golden fish back into the sea.But the fisherman’s wife was angry.“You should ask for a bigger wooden basin!” she shouted.The fisherman went to the seaside and told the golden fish.“Don’t worry, she has a new basin now,” the golden fish said.The fisherman went home.But the wife was even angrier.“I want a large house!” The fisherman went to tell the golden fish again.But the old woman was never satisfied.“I want to be the queen of the sea!And I want the golden fish to serve me!”

The fisherman went to tell the golden fish.The golden fish swam away without saying anything.The fisherman walked back.His wife was in her cold clothes.Her old and broken wooden basin was next to her.根据短文内容，判断下列各句正误。正确的在题号前括号内写“T”，错误的写“F”。11.The fisherman caught the golden fish three times.12.The fisherman freed the golden fish after he caught it.13.The fisherman’s wife was really happy every time when her husband came back.14.The fisherman’s wife got a new basin, a large house and became the queen of the sea at last.15.The golden fish didn’t say a word but to swim away in the bed.文章大意：本文是一个寓言故事，讲了一个贪得无厌，最终以无所获得故事。11.F【解析】整体理解题 从文中可知渔夫并没有捉住金鱼三次。12.T 【解析】细节理解题。从第二段的““Thank you, but I don’t want anything,” the fisherman said.He put the golden fish back into the sea.”可知渔夫抓住金鱼之后，就把它放了。

13.F 【解析】推理判断题。渔夫的妻子每次都不满意。

14.F 【解析】整体理解题 渔夫的妻子得到了一个澡盆和新房子，但没有成为皇后。

15.T 【解析】细节理解题 从最后一段的“The golden fish swam away without saying anything.”可知答案。

二次根式

知识回顾

1.二次根式：式子(ge;0)叫做二次根式。2.最简二次根式：必须同时满足下列条件：

⑴被开方数中不含开方开的尽的因数或因式;⑵被开方数中不含分母;⑶分母中不含根式。3.同类二次根式：

二次根式化成最简二次根式后，若被开方数相同，则这几个二次根式就是同类二次根式。4.二次根式的性质：(1)()2=(ge;0);(2)5.二次根式的运算：

(1)因式的外移和内移：如果被开方数中有的因式能够开得尽方，那么，就可以用它的算术根代替而移到根号外面;如果被开方数是代数和的形式，那么先解因式，•变形为积的形式，再移因式到根号外面，反之也可以将根号外面的正因式平方后移到根号里面.(2)二次根式的加减法：先把二次根式化成最简二次根式再合并同类二次根式.(3)二次根式的乘除法：二次根式相乘(除)，将被开方数相乘(除)，所得的积(商)仍作积(商)的被开方数并将运算结果化为最简二次根式.=(age;0，bge;0);(bge;0，agt;0).(4)有理数的加法交换律、结合律，乘法交换律及结合律，•乘法对加法的分配律以及多项式的乘法公式，都适用于二次根式的运算.勾股定理1.勾股定理：如果直角三角形的两直角边长分别为a，b，斜边长为c，那么a2+b2=c2。

2.勾股定理逆定理：如果三角形三边长a,b,c满足a2+b2=c2。，那么这个三角形是直角三角形。3.直角三角形的性质

(1)、直角三角形的两个锐角互余。可表示如下：ang;C=90deg;ang;A+ang;B=90deg;(2)、在直角三角形中，30deg;角所对的直角边等于斜边的一半。ang;A=30deg;可表示如下：BC=AB ang;C=90deg;(3)、直角三角形斜边上的中线等于斜边的一半 ang;ACB=90deg;可表示如下：CD=AB=BD=AD D为AB的中点

4、直角三角形的判定

1、有一个角是直角的三角形是直角三角形。

2、如果三角形一边上的中线等于这边的一半，那么这个三角形是直角三角形。

3、勾股定理的逆定理：如果三角形的三边长a，b，c有关系，那么这个三角形是直角三角形。

5、三角形中的中位线

连接三角形两边中点的线段叫做三角形的中位线。(1)三角形共有三条中位线，并且它们又重新构成一个新的三角形。

(2)要会区别三角形中线与中位线。

三角形中位线定理：三角形的中位线平行于第三边，并且等于它的一半。

四边形

1.四边形的内角和与外角和定理：(1)四边形的内角和等于360deg;;(2)四边形的外角和等于360deg;.2.多边形的内角和与外角和定理：(1)n边形的内角和等于(n-2)180deg;;(2)任意多边形的外角和等于360deg;12.等腰梯形的判定：

(四边形ABCD是等腰梯形

(3)∵ABCD是梯形且AD∥BC

∵AC=BD

there4;ABCD四边形是等腰梯形 14.三角形中位线定理：

三角形的中位线平行第三边，并且等于它的一半.15.梯形中位线定理：

梯形的中位线平行于两底，并且等于两底和的一半.一次函数

一、正比例函数与一次函数的概念：

一般地，形如y=kx(k为常数，且kne;0)的函数叫做正比例函数.其中k叫做比例系数。

一般地，形如y=kx+b(k,b为常数，且kne;0)的函数叫做一次函数.当b=0时,y=kx+b即为y=kx,所以正比例函数，是一次函数的特例.二、正比例函数的图象与性质：

(1)图象:正比例函数y=kx(k是常数，kne;0))的图象是经过原点的一条直线，我们称它为直线y=kx。

(2)性质:当kgt;0时,直线y=kx经过第三，一象限，从左向右上升，即随着x的增大y也增大;当k0，bgt;0图像经过一、二、三象限;(2)kgt;0，blt;0图像经过一、三、四象限;(3)kgt;0，b=0图像经过一、三象限;(4)klt;0，bgt;0图像经过一、二、四象限;(5)klt;0，blt;0图像经过二、三、四象限;(6)klt;0，b=0图像经过二、四象限。

一次函数表达式的确定

求一次函数y=kx+b(k、b是常数，kne;0)时，需要由两个点来确定;求正比例函数y=kx(kne;0)时，只需一个点即可.5.一次函数与二元一次方程组：

解方程组

从“数”的角度看，自变量(x)为何值时两个函数的值相等.并

求出这个函数值

解方程组从“形”的角度看，确定两直线交点的坐标.数据的分析

数据的代表：平均数、众数、中位数、极差、方差

一元二次方程知识点总结

一、知识框架

二、知识点、概念总结

1.一元二次方程：方程两边都是整式，只含有一个未知数(一元)，并且未知数的最高次数是2(二次)的方程，叫做一元二次方程。

2.一元二次方程有四个特点：(1)含有一个未知数;(2)且未知数次数最高次数是2;(3)是整式方程。要判断一个方程是否为一元二次方程，先看它是否为整式方程，若是，再对它进行整理。如果能整理为ax2+bx+c=0(ane;0)的形式，则这个方程就为一元二次方程。

(4)将方程化为一般形式：ax2+bx+c=0时，应满足(ane;0)3.一元二次方程的一般形式：一般地，任何一个关于x的一元二次方程，经过整理，•都能化成如下形式ax2+bx+c=0(ane;0)。

一个一元二次方程经过整理化成ax2+bx+c=0(ane;0)后，其中ax2是二次项，a是二次项系数;bx是一次项，b是一次项系数;c是常数项。4.一元二次方程的解法(1)直接开平方法

利用平方根的定义直接开平方求一元二次方程的解的方法叫做直接开平方法。直接开平方法适用于解形如的一元二次方程。根据平方根的定义可知，是b的平方根，当时，，当b”、“=”、“lt;”)。

16.如图，在四边形ABCD中ABCD，若加上ADBC，则四边形ABCD为平行四边形。现在请你添加一个适当的条件：，使得四边形AECF为平行四边形.(图中不再添加点和线)转眼之间一个学期也将过去了，同学们也迎来了期末考试，希望上文为大家提供的八年级下册数学期末考试知识点归纳，能帮助到大家。

6.动词的过去进行时； 【名师讲解】 1.bring/take

Bring表示“带来、拿来”，指从别处朝说话人所在或将在的地方“带来、拿来”。而take则表示“拿去、带走”，它表示的方向与bring相反，指从说话人所在地“拿走、带走”。如：

Bring me the book, please.把那本书给我拿来。

Take some food to the old man.给那位老人带去些食物。2.somebody/ anybody/nobody

一般说来，somebody用于定句，anybody用于否定句、疑问句和条件状语从句。例如： Somebody came to see you when you were out.你出来时有人来见你。Does anybody live on this island? 有人在这岛上住吗？ I didn't see anybody there.我在那儿谁也没看见。

Don't let anybody in.I'm too busy to see anybody.别让任何人进来。我太忙，谁也不想见。

There is nobody in the room.房间里没人。

Nobody told me that you were ill, so I didn't know about it.谁也没告诉我你病了。所以我不知道。3.listen, listen to, hear

这三个词意思都是“听”，但是它们的用法不完全相同。它们的区别在于：

(1)listen 只用于不及物动词，后面接人或人物做宾语，着重于“倾听”，指的是有意识的动作，至于是否听到，并非强调的重点。如：

Listen!Someone is singing in the classroom.听！有人在教室唱歌。

(2)listen to 为listen的及物形式，后面一定要接人或物做宾语，这里的to是介词。如：

Do you like listening to light music?你喜欢听轻音乐吗？

(3)hear 可用作及物动词，也可用作不及物动词，意思是“听到、听见”，指用耳朵听到了某个声音，表示无意识的动作，着重于听的能力和结果。如：

We hear with our ears.我们用耳朵听。

She listens but hears nothing.她听了听，但是什么也没有听见。4.many/ much/ a few/ a little/ few/ little(1)many修饰可数名词，much修饰不可数名词；都表示许多。例如： He has many books.他有许多书。

He drank much milk.他喝了许多牛奶。

(2)a few和a little都表示“有一点儿”，侧重于肯定，相当于“some”，但a few修 饰可数名词，a little修饰不可数名词，例如：

He has a few friends in London.他在伦敦有一些朋友

Would you like some coffee? Yes, just a little.喝点咖啡好吗？好的，只要一点。

(3)few和little表示“几乎没有”，侧重否定。few后接可数名词，little后接不可数名词。例如：

He is a strange man.He has few words.他是个怪人，他几乎不说什么话。Hurry up, there is little time left.赶快，没什么时间了。

5.either/ neither/ both

either可作形容词，一般指“两者中的任何一个”。有时也可表示“两个都„„”的意思，后跟名词的单数形式；neither: 指两者中没有一个，全否定；both: 指两者都，肯定。句中可作主语、宾语和定语，both后面应跟名词的复数形式。如：

Neither of the films is good.两部电影都不好。（没有一部是好的）Either of the films is good.两部电影都不错。（谓语动词用单数）

Both the teachers often answer the questions.这两个老师都常常解答问题。6.take part in/join

take part in参加某种活动;join参加，加入某一政党或组织。例如： Can you take part in my party.你能来参加我的派对吗？

We often take part in many school activities.我们经常参加学校里的一些活动。He joined the party in 1963.他1963年入的党。

My little brother joined the army last year.我小弟去年参的军。7.quite/ rather/ very

(1)quite 表示程度“很，十分，完全地”，“相当”。如： She is quite right.她对极了。

That's not quite what I want.那并不完全是我所要的。

rather 表示程度上的“相当”，比预想地程度要大，通常用在不喜欢的情况下。如：It's rather cold today.今天的天气相当冷。(3)very表示程度“很，甚，极其，非常”，用于修饰形容词或副词，既可用在喜欢的情况下，也可用于不喜欢的情况下。应注意“a very +形容词+可数名词的单数”结构中，“a”应置于“very”之前，该结构相当“quite a/an +形容词+名词”的结构。如：

Two months is quite a long time./ a very long time.两个月是一段很长的时间。

It's a very nice day / quite a nice day.今天天气很好。
