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.根據(jù)短文內(nèi)容，判斷下列各句正誤。正確的在題號(hào)前括號(hào)內(nèi)寫“T”，錯(cuò)誤的寫“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：本文是一個(gè)寓言故事，講了一個(gè)貪得無厭，最終以無所獲得故事。11.F【解析】整體理解題 從文中可知漁夫并沒有捉住金魚三次。12.T 【解析】細(xì)節(jié)理解題。從第二段的““Thank you, but I don’t want anything,” the fisherman said.He put the golden fish back into the sea.”可知漁夫抓住金魚之后，就把它放了。

13.F 【解析】推理判斷題。漁夫的妻子每次都不滿意。

14.F 【解析】整體理解題 漁夫的妻子得到了一個(gè)澡盆和新房子，但沒有成為皇后。

15.T 【解析】細(xì)節(jié)理解題 從最后一段的“The golden fish swam away without saying anything.”可知答案。

三．書面表達(dá)

請(qǐng)你根據(jù)下表中所提供的信息以“Learn to express thanks”為題，用英語寫一篇演講稿。背 景 1.認(rèn)為上中學(xué)時(shí)吃好穿好是應(yīng)該的； 2.走向社會(huì)后沒有感恩意識(shí)。

學(xué)會(huì)感恩 1.感謝社會(huì)提供良好的教育機(jī)會(huì)； 2.感謝父母供養(yǎng)自己上學(xué)； 3.感謝老師傳授知識(shí)；

4.感謝朋友的鼓勵(lì)與幫助。

參考詞匯：enter society 進(jìn)入社會(huì)，sense of thanks 感恩意識(shí)，behavior 行為 5.詞數(shù)：80詞左右。開頭和結(jié)尾已給出，不計(jì)入總詞數(shù)。Good morning, boys and girls!The topic of my speech today is “Learn to express thanks”.In the future, we should never forget our society, parents, teachers and friends.At present, we should study harder to make our world more beautiful.Thank you for your listening

二次根式

知識(shí)回顧

1.二次根式：式子(ge;0)叫做二次根式。2.最簡二次根式：必須同時(shí)滿足下列條件：

⑴被開方數(shù)中不含開方開的盡的因數(shù)或因式;⑵被開方數(shù)中不含分母;⑶分母中不含根式。3.同類二次根式：

二次根式化成最簡二次根式后，若被開方數(shù)相同，則這幾個(gè)二次根式就是同類二次根式。4.二次根式的性質(zhì)：(1)()2=(ge;0);(2)5.二次根式的運(yùn)算：

(1)因式的外移和內(nèi)移：如果被開方數(shù)中有的因式能夠開得盡方，那么，就可以用它的算術(shù)根代替而移到根號(hào)外面;如果被開方數(shù)是代數(shù)和的形式，那么先解因式，?變形為積的形式，再移因式到根號(hào)外面，反之也可以將根號(hào)外面的正因式平方后移到根號(hào)里面.(2)二次根式的加減法：先把二次根式化成最簡二次根式再合并同類二次根式.(3)二次根式的乘除法：二次根式相乘(除)，將被開方數(shù)相乘(除)，所得的積(商)仍作積(商)的被開方數(shù)并將運(yùn)算結(jié)果化為最簡二次根式.=(age;0，bge;0);(bge;0，agt;0).(4)有理數(shù)的加法交換律、結(jié)合律，乘法交換律及結(jié)合律，?乘法對(duì)加法的分配律以及多項(xiàng)式的乘法公式，都適用于二次根式的運(yùn)算.勾股定理1.勾股定理：如果直角三角形的兩直角邊長分別為a，b，斜邊長為c，那么a2+b2=c2。

2.勾股定理逆定理：如果三角形三邊長a,b,c滿足a2+b2=c2。，那么這個(gè)三角形是直角三角形。3.直角三角形的性質(zhì)

(1)、直角三角形的兩個(gè)銳角互余?？杀硎救缦拢篴ng;C=90deg;ang;A+ang;B=90deg;(2)、在直角三角形中，30deg;角所對(duì)的直角邊等于斜邊的一半。ang;A=30deg;可表示如下：BC=AB ang;C=90deg;(3)、直角三角形斜邊上的中線等于斜邊的一半 ang;ACB=90deg;可表示如下：CD=AB=BD=AD D為AB的中點(diǎn)

4、直角三角形的判定

1、有一個(gè)角是直角的三角形是直角三角形。

2、如果三角形一邊上的中線等于這邊的一半，那么這個(gè)三角形是直角三角形。

3、勾股定理的逆定理：如果三角形的三邊長a，b，c有關(guān)系，那么這個(gè)三角形是直角三角形。

5、三角形中的中位線

連接三角形兩邊中點(diǎn)的線段叫做三角形的中位線。(1)三角形共有三條中位線，并且它們又重新構(gòu)成一個(gè)新的三角形。

(2)要會(huì)區(qū)別三角形中線與中位線。

三角形中位線定理：三角形的中位線平行于第三邊，并且等于它的一半。

四邊形

1.四邊形的內(nèi)角和與外角和定理：(1)四邊形的內(nèi)角和等于360deg;;(2)四邊形的外角和等于360deg;.2.多邊形的內(nèi)角和與外角和定理：(1)n邊形的內(nèi)角和等于(n-2)180deg;;(2)任意多邊形的外角和等于360deg;12.等腰梯形的判定：

(四邊形ABCD是等腰梯形

(3)∵ABCD是梯形且AD∥BC

∵AC=BD

there4;ABCD四邊形是等腰梯形 14.三角形中位線定理：

三角形的中位線平行第三邊，并且等于它的一半.15.梯形中位線定理：

梯形的中位線平行于兩底，并且等于兩底和的一半.一次函數(shù)

一、正比例函數(shù)與一次函數(shù)的概念：

一般地，形如y=kx(k為常數(shù)，且kne;0)的函數(shù)叫做正比例函數(shù).其中k叫做比例系數(shù)。

一般地，形如y=kx+b(k,b為常數(shù)，且kne;0)的函數(shù)叫做一次函數(shù).當(dāng)b=0時(shí),y=kx+b即為y=kx,所以正比例函數(shù)，是一次函數(shù)的特例.二、正比例函數(shù)的圖象與性質(zhì)：

(1)圖象:正比例函數(shù)y=kx(k是常數(shù)，kne;0))的圖象是經(jīng)過原點(diǎn)的一條直線，我們稱它為直線y=kx。

(2)性質(zhì):當(dāng)kgt;0時(shí),直線y=kx經(jīng)過第三，一象限，從左向右上升，即隨著x的增大y也增大;當(dāng)k0，bgt;0圖像經(jīng)過一、二、三象限;(2)kgt;0，blt;0圖像經(jīng)過一、三、四象限;(3)kgt;0，b=0圖像經(jīng)過一、三象限;(4)klt;0，bgt;0圖像經(jīng)過一、二、四象限;(5)klt;0，blt;0圖像經(jīng)過二、三、四象限;(6)klt;0，b=0圖像經(jīng)過二、四象限。

一次函數(shù)表達(dá)式的確定

求一次函數(shù)y=kx+b(k、b是常數(shù)，kne;0)時(shí)，需要由兩個(gè)點(diǎn)來確定;求正比例函數(shù)y=kx(kne;0)時(shí)，只需一個(gè)點(diǎn)即可.5.一次函數(shù)與二元一次方程組：

解方程組

從“數(shù)”的角度看，自變量(x)為何值時(shí)兩個(gè)函數(shù)的值相等.并

求出這個(gè)函數(shù)值

解方程組從“形”的角度看，確定兩直線交點(diǎn)的坐標(biāo).數(shù)據(jù)的分析

數(shù)據(jù)的代表：平均數(shù)、眾數(shù)、中位數(shù)、極差、方差

一元二次方程知識(shí)點(diǎn)總結(jié)

一、知識(shí)框架

二、知識(shí)點(diǎn)、概念總結(jié)

1.一元二次方程：方程兩邊都是整式，只含有一個(gè)未知數(shù)(一元)，并且未知數(shù)的最高次數(shù)是2(二次)的方程，叫做一元二次方程。

2.一元二次方程有四個(gè)特點(diǎn)：(1)含有一個(gè)未知數(shù);(2)且未知數(shù)次數(shù)最高次數(shù)是2;(3)是整式方程。要判斷一個(gè)方程是否為一元二次方程，先看它是否為整式方程，若是，再對(duì)它進(jìn)行整理。如果能整理為ax2+bx+c=0(ane;0)的形式，則這個(gè)方程就為一元二次方程。

(4)將方程化為一般形式：ax2+bx+c=0時(shí)，應(yīng)滿足(ane;0)3.一元二次方程的一般形式：一般地，任何一個(gè)關(guān)于x的一元二次方程，經(jīng)過整理，?都能化成如下形式ax2+bx+c=0(ane;0)。

一個(gè)一元二次方程經(jīng)過整理化成ax2+bx+c=0(ane;0)后，其中ax2是二次項(xiàng)，a是二次項(xiàng)系數(shù);bx是一次項(xiàng)，b是一次項(xiàng)系數(shù);c是常數(shù)項(xiàng)。4.一元二次方程的解法(1)直接開平方法

利用平方根的定義直接開平方求一元二次方程的解的方法叫做直接開平方法。直接開平方法適用于解形如的一元二次方程。根據(jù)平方根的定義可知，是b的平方根，當(dāng)時(shí)，，當(dāng)b”、“=”、“l(fā)t;”)。

16.如圖，在四邊形ABCD中ABCD，若加上ADBC，則四邊形ABCD為平行四邊形?，F(xiàn)在請(qǐng)你添加一個(gè)適當(dāng)?shù)臈l件：，使得四邊形AECF為平行四邊形.(圖中不再添加點(diǎn)和線)轉(zhuǎn)眼之間一個(gè)學(xué)期也將過去了，同學(xué)們也迎來了期末考試，希望上文為大家提供的八年級(jí)下冊(cè)數(shù)學(xué)期末考試知識(shí)點(diǎn)歸納，能幫助到大家。

6.動(dòng)詞的過去進(jìn)行時(shí)； 【名師講解】 1.bring/take

Bring表示“帶來、拿來”，指從別處朝說話人所在或?qū)⒃诘牡胤健皫?、拿來”。而take則表示“拿去、帶走”，它表示的方向與bring相反，指從說話人所在地“拿走、帶走”。如：

Bring me the book, please.把那本書給我拿來。

Take some food to the old man.給那位老人帶去些食物。2.somebody/ anybody/nobody

一般說來，somebody用于定句，anybody用于否定句、疑問句和條件狀語從句。例如： Somebody came to see you when you were out.你出來時(shí)有人來見你。Does anybody live on this island? 有人在這島上住嗎？ I didn't see anybody there.我在那兒誰也沒看見。

這三個(gè)詞意思都是“聽”，但是它們的用法不完全相同。它們的區(qū)別在于：

(1)listen 只用于不及物動(dòng)詞，后面接人或人物做賓語，著重于“傾聽”，指的是有意識(shí)的動(dòng)作，至于是否聽到，并非強(qiáng)調(diào)的重點(diǎn)。如：

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

(2)listen to 為listen的及物形式，后面一定要接人或物做賓語，這里的to是介詞。如：

Do you like listening to light music?你喜歡聽輕音樂嗎？

(3)hear 可用作及物動(dòng)詞，也可用作不及物動(dòng)詞，意思是“聽到、聽見”，指用耳朵聽到了某個(gè)聲音，表示無意識(shí)的動(dòng)作，著重于聽的能力和結(jié)果。如：

We hear with our ears.我們用耳朵聽。

She listens but hears nothing.她聽了聽，但是什么也沒有聽見。4.many/ much/ a few/ a little/ few/ little(1)many修飾可數(shù)名詞，much修飾不可數(shù)名詞；都表示許多。例如： He has many books.他有許多書。

He drank much milk.他喝了許多牛奶。

(2)a few和a little都表示“有一點(diǎn)兒”，側(cè)重于肯定，相當(dāng)于“some”，但a few修 飾可數(shù)名詞，a little修飾不可數(shù)名詞，例如：

He has a few friends in London.他在倫敦有一些朋友

Would you like some coffee? Yes, just a little.喝點(diǎn)咖啡好嗎？好的，只要一點(diǎn)。

(3)few和little表示“幾乎沒有”，側(cè)重否定。few后接可數(shù)名詞，little后接不可數(shù)名詞。例如：

He is a strange man.He has few words.他是個(gè)怪人，他幾乎不說什么話。Hurry up, there is little time left.趕快，沒什么時(shí)間了。

5.either/ neither/ both

either可作形容詞，一般指“兩者中的任何一個(gè)”。有時(shí)也可表示“兩個(gè)都??”的意思，后跟名詞的單數(shù)形式；neither: 指兩者中沒有一個(gè)，全否定；both: 指兩者都，肯定。句中可作主語、賓語和定語，both后面應(yīng)跟名詞的復(fù)數(shù)形式。如：

Neither of the films is good.兩部電影都不好。（沒有一部是好的）Either of the films is good.兩部電影都不錯(cuò)。（謂語動(dòng)詞用單數(shù)）

Both the teachers often answer the questions.這兩個(gè)老師都常常解答問題。6.take part in/join

take part in參加某種活動(dòng);join參加，加入某一政黨或組織。例如： Can you take part in my party.你能來參加我的派對(duì)嗎？

We often take part in many school activities.我們經(jīng)常參加學(xué)校里的一些活動(dòng)。He joined the party in 1963.他1963年入的黨。

My little brother joined the army last year.我小弟去年參的軍。7.quite/ rather/ very

(1)quite 表示程度“很，十分，完全地”，“相當(dāng)”。如： She is quite right.她對(duì)極了。

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

rather 表示程度上的“相當(dāng)”，比預(yù)想地程度要大，通常用在不喜歡的情況下。如：It's rather cold today.今天的天氣相當(dāng)冷。(3)very表示程度“很，甚，極其，非?！?，用于修飾形容詞或副詞，既可用在喜歡的情況下，也可用于不喜歡的情況下。應(yīng)注意“a very +形容詞+可數(shù)名詞的單數(shù)”結(jié)構(gòu)中，“a”應(yīng)置于“very”之前，該結(jié)構(gòu)相當(dāng)“quite a/an +形容詞+名詞”的結(jié)構(gòu)。如：

Two months is quite a long time./ a very long time.兩個(gè)月是一段很長的時(shí)間。

It's a very nice day / quite a nice day.今天天氣很好。
