Teacher can deal with some language points or useful words:

1．Did you have a good flight?

2．Did you sleep at all on the plane?

At all主要用于否定句、疑問(wèn)句和條件句，用以加強(qiáng)語(yǔ)氣，與否定詞連用，表示“一點(diǎn)也不”

2.Reading

①T says to Ss: Today we will read a passage about the historical development of English over the past fifty year, developing from a widely spoken national language to a universally spoken world language.②let Ss read the text silently, and then fill in blanks(slide show)1

The English is the mother tongue of 375 million people in English speaking countries such as the US, UK, Canada, Australia, New Zealand, South Africa and Ireland among others.2

The number of people who learn English as foreign language is more than 750 million.Most people learn English for five or six years at high school.3

English is the working language of most international organizations, international trade and tourism.English is also the language of global culture, such as popular music and the Internet.③let Ss read the text again, and then work in pairs to answer another questions:

Why is it becoming more and more important to have a good knowledge of English?

In which countries do we find most native speakers of English? Give the names of the three countries.Living in China you can use English every day in different situations.Give two examples.④ play the tape to Ss and let them follow and repeat the text.⑤ deal with some language points and new words

1.There many people speak English as a first or a second language.“ the+序數(shù)詞”用來(lái)表示編號(hào)，強(qiáng)調(diào)“第??”

e.g.Who is the first man to land on the moon?

“ a+序數(shù)詞”強(qiáng)調(diào)“再一??，又??”

e.g.We’ll have to do it a second time.He had jumped two times but failed;he tried to jump a third time.2.Chinese businessmen, taxi drivers and students talk with them using English.Using English是現(xiàn)在分詞短語(yǔ)做方式狀語(yǔ)?，F(xiàn)在份詞作狀語(yǔ)，表示主語(yǔ)正在進(jìn)行的另一動(dòng)作，對(duì)謂語(yǔ)表示的主要?jiǎng)幼骷右孕揎椇团阋r，分詞動(dòng)作與謂語(yǔ)動(dòng)作都必須是同一主語(yǔ)進(jìn)行的，它可以表示時(shí)間、原因、方式、伴隨狀況等。

e.g.Arriving at the bus stop, we found his sister there.表示時(shí)間

Seeing nobody at home, she decided to leave them a note.原因

Travelling by car, the girls visited many places.方式

They walked along the street, talking and laughing.伴隨狀況

3.There are more than 42 countries where the majority of the people speak English.大多數(shù)人講英語(yǔ)的國(guó)家有42個(gè)還多。

more than意為“超過(guò)，不僅僅”，相當(dāng)于over, not only。例如：

（1）There ar more than 2,000 students in our school.我們學(xué)校有2，000多人。

（2）He is more than 40 years old.他40多歲了。

（3）She is more than a teacher.She loves us ilke a mother.她不僅僅是個(gè)老師，她像母親一樣愛(ài)護(hù)我們。

where the majority of the people speak English是定語(yǔ)從句，修飾countries。where在定語(yǔ)從句中作狀語(yǔ)，表示地點(diǎn)。又如：

（1）Last month I visited the village where I was born.上個(gè)月我去拜訪了我出生的那個(gè)村子。

（2）Zhengzhou is the place where his father once worked.鄭州是他父親曾經(jīng)工作過(guò)的地方。

majority是句詞，意為“多數(shù)，大多數(shù)，半數(shù)以上”。例如：

（1）He was supported by the great majority of the people.他受到了廣大人民群眾的擁護(hù)。

（2）The majority of his books are kept upstairs.他的大部分藏書(shū)在樓上。

（3）The majority were/was against the plan.多數(shù)人不贊成這個(gè)計(jì)劃。

4.However, the number of people who learn English as a foreign language is more than 750 million.然而，把英語(yǔ)作為外語(yǔ)來(lái)學(xué)的人有7億5千萬(wàn)。

the number of/a number of 辨析

the number of意為“??的數(shù)目，??的號(hào)碼”作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)；a number of意為“一些，許多”，作定語(yǔ)，修飾復(fù)數(shù)名詞，作主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞用復(fù)數(shù)。例如：

（1）The number of the students in our school is more than 2,000.我們學(xué)校有2，000多人。

（2）The number of my telephone is 0371-6949192.我的電話號(hào)碼是0371-6949192.（3）A number of students in our class have been to Beijing.我們班有很多同學(xué)去過(guò)北京。

2．牛頓第二定律。

教學(xué)難點(diǎn)

牛頓第二定律的意義。

教學(xué)方法

實(shí)驗(yàn)法、講授法、歸納法

教學(xué)用具

兩輛質(zhì)量相同的小車，光滑的水平板（一端帶有定滑輪）；砝碼（一盒），細(xì)繩、夾子 課時(shí)安排 2課時(shí)

教學(xué)過(guò)程

一、導(dǎo)入新課

1．提問(wèn)：什么是物體運(yùn)動(dòng)狀態(tài)的改變？物體運(yùn)動(dòng)狀態(tài)發(fā)生改變的原因是什么？

2．引入新課：

通過(guò)上節(jié)課的學(xué)習(xí)，我們已知道：物體運(yùn)動(dòng)狀態(tài)改變時(shí)產(chǎn)生加速度，而產(chǎn)生的加速度又和物體的質(zhì)量及所受力的大小有關(guān)，那么：加速度跟物體所受力的大小及物體質(zhì)量之間有什么關(guān)系呢？本節(jié)課我們就來(lái)研究這個(gè)問(wèn)題。

二、新課教學(xué)

（一）用投影片出示本節(jié)課的學(xué)習(xí)目標(biāo)：

1．理解加速度與力的關(guān)系；

2．理解加速度與質(zhì)量的關(guān)系

3．理解牛頓第二定律的內(nèi)容。

（二）學(xué)習(xí)目標(biāo)完成過(guò)程：

1、加速度和力的關(guān)系：

（1）用投影片出示本節(jié)課所用的實(shí)驗(yàn)裝置，教師進(jìn)行講解：圖中是兩輛質(zhì)量相同的小車，放在光滑的水平板上，小車的前端各系上細(xì)繩，繩的另一端跨過(guò)定滑輪各掛一個(gè)小盤(pán)，盤(pán)里放有數(shù)量不等的砝碼，使兩輛小車在不同的拉力下做勻加速運(yùn)動(dòng)。

（2）對(duì)本次實(shí)驗(yàn)中說(shuō)明的兩個(gè)問(wèn)題

a：砝碼跟小車相比質(zhì)量較小，細(xì)繩對(duì)小車的拉力近似地等于砝碼所受的重力。

b：用一只夾子夾住兩根細(xì)繩，以同時(shí)控控制兩輛小車。

（3）實(shí)驗(yàn)的做法：

a：在兩砝碼盤(pán)中放不同數(shù)量的砝碼，以使兩小車所受的拉力不同。

高考資源網(wǎng) 2006精品資料系列

b：打開(kāi)夾子，讓兩輛小車同時(shí)從靜止開(kāi)始運(yùn)動(dòng)，一段時(shí)間后關(guān)上夾子，讓它們同時(shí)停下來(lái)。

（4）需觀察的現(xiàn)象，觀察兩輛車在相等的時(shí)間里，所發(fā)生的位移的大小。（實(shí)驗(yàn)現(xiàn)象：所受拉力大的那輛小車，位移大）

（5）分析推理：

a：由公式s1?at2得到在時(shí)間t一定時(shí)，位移s和加速度a成正比；

2b：由實(shí)驗(yàn)現(xiàn)象得到：小車的位移與他們所受的拉力成正比。

c：推理得到結(jié)論：對(duì)質(zhì)量相同的物體，物體的加速度跟作用在物體上的力成正比，即：

a1F1?或a?F a2F2a1F1?a2F2

（6）鞏固練習(xí)：

a．據(jù)得到：要使物體在短時(shí)間內(nèi)速度的改變很大，即加速度很大，就必須給物體提供。

b．競(jìng)賽用的小汽車，要求起動(dòng)后幾秒鐘內(nèi)速度由零達(dá)到60m/s以上，他們?yōu)槭裁匆b備功率很大的發(fā)動(dòng)機(jī)？

2：加速度和質(zhì)量的關(guān)系：

（1）實(shí)驗(yàn)裝置同上；

（2）說(shuō)明與前次實(shí)驗(yàn)的不同。

前一次實(shí)驗(yàn)中，我們是保持小車質(zhì)量不變，而改變小車所受力的大小，來(lái)研究加速度和力之間的關(guān)系的。

本次實(shí)驗(yàn)是使兩輛小車所受拉力相同，而在一輛小車上加放砝碼的，以增大質(zhì)量，研究加速度和質(zhì)量之間關(guān)系的。

（3）實(shí)驗(yàn)現(xiàn)象：

在相同的時(shí)間里，質(zhì)量小的那輛小車的位移大。

（4）分析推理，得到結(jié)論：

在相同的力作用下，物體的加速度跟物體的質(zhì)量成反比，即

a1/a2=m2/m1或a∝m3：牛頓第二運(yùn)動(dòng)定律

（1）綜合上述實(shí)驗(yàn)中得到的兩個(gè)關(guān)系，得到下述結(jié)論：

物體的加速度跟作用力成正比，跟物體的質(zhì)量成反比，且加速度的方向跟引起這個(gè)加速度的力的方向相同。

（2）公式表示：

a∝F或者F∝ma m即：F=kma

a：如果每個(gè)物理量都采用國(guó)際單位，k＝1；

高考資源網(wǎng) 2006精品資料系列

b：力的單位（牛頓）的定義：使質(zhì)量為1千克的物體產(chǎn)生1m/s2的加速度的力叫做1牛頓。

（3）推廣：上面我們研究的是物體受到一個(gè)力作用的情況，當(dāng)物體受到幾個(gè)力作用時(shí)，上述關(guān)系可推廣為：

物體的加速度跟所受的合力成正比，跟物體的質(zhì)量成反比，加速度的放心跟合力的方向相同。即F合＝ma。

（4）介紹F合和a的瞬時(shí)對(duì)應(yīng)關(guān)系

a：只有物體受到力的作用，物體才具有加速度。

b：力恒定不變，加速度也恒定不變。

c：力隨著時(shí)間改變，加速度也隨著時(shí)間改變。

d：力停止作用，加速度也隨即消失。

4：例題分析（課本例題）

（1）學(xué)生閱讀例題內(nèi)容

（2）分析：

??質(zhì)量m已知???必須先求F1和F2的合力，而合力的大小可

要求物體的加速度?以用作圖法求解，也可以用計(jì)算法求解。

（3）用投影片展示解題過(guò)程：

如圖所示，建立平面直角坐標(biāo)系，把力F1和F2分別沿x軸和y軸的方向分解F1的兩個(gè)分力為：

F1x?F1xcos60o,F2y?F2sin60o

F2的兩個(gè)分力為：F2xo?F2cos60o,F2y?F2sin60

F1y和F2y大小相等，方向相反，相互抵消，F(xiàn)1x和F2x的方向相同，所以：

F合?F1x?F2x?F1cos60o?F2cos60o?5N?5N?10N

已知合力F合和質(zhì)量m，據(jù)F合＝ma，即可求得：

10Na?F合??5m/s2

2kg

三：小結(jié)

1：本節(jié)課的研究方法——控制變量法

2：牛頓第二運(yùn)動(dòng)定律確定了a和F之間的大小關(guān)系，也確定的a和F的方向關(guān)系

3：求解合力時(shí)，可采用建立平面直角坐標(biāo)系，將各個(gè)力沿x軸和y軸分解，最后求合力的方法。

(一)導(dǎo)入：首先在學(xué)生對(duì)英語(yǔ)是世界上最廣泛使用的語(yǔ)言和越來(lái)越多的人在學(xué)習(xí)英語(yǔ)現(xiàn)有情況了解的基礎(chǔ)上，引出問(wèn)題: “Do you know how many countries use English as their mother tongue? Do you know something about English around the world？”

在學(xué)生思索時(shí)，引出課題English around the world。接著再詢問(wèn)學(xué)生： What language has the largest number of speakers in the world? What language is the most widely spoken and used in the world? How many countries do you know use English as their mother tongue?(二)Pre-reading（讀前準(zhǔn)備）：

在學(xué)生回答了以上問(wèn)題后，我讓學(xué)生看這一部分課本上所設(shè)的兩個(gè)問(wèn)題： 1)How many languages do you speak? Which is your native language? 2)If you speak more than one language, in what situation do you use the languages?(三)Reading：使學(xué)生了解英語(yǔ)在當(dāng)今世界范圍內(nèi)人們生活中扮演的不同角色及其重要意義。任務(wù) 1：Listen to the tape，聽(tīng)錄音，然后讓學(xué)生盡力得出大意并且回答問(wèn)題 1.How many countries are there where the majority of people speak English? 2.How is English used in Hong Kong? 3.What language should we use on the Internet so that we can communicate with people around the world? 任務(wù)2：讓學(xué)生帶著問(wèn)題閱讀課文（scanning）。有目的性閱讀是閱讀訓(xùn)練一種技巧，并且提醒學(xué)生不用太多花大多注意力在地名和新單詞上面，集中精力探究文章內(nèi)容。概括每段段落大意。

Paragraph 1: The spread of the English language in the world

Paragraph 2: Native speaker can understand each other but they may not be able to understand everything.Paragraph 3: All languages change when cultures communicate with one another.Paragraph 4: English is spoken as a foreign language or second language in Africa and Asia.任務(wù)3：根據(jù)課文內(nèi)容，判斷句子對(duì)與錯(cuò)。

Give the names of three counties.3）Living in China you can use English every day in different situations.Give two examples.給學(xué)生五分鐘的時(shí)間分組討論，然后讓每組的代表給出答案（完成本課教學(xué)目標(biāo)）。教師在布置任務(wù)后，應(yīng)監(jiān)控各小組的活動(dòng)，適當(dāng)?shù)臅r(shí)候可以參與到學(xué)生的活動(dòng)中去。在活動(dòng)中，教師多用評(píng)價(jià)性語(yǔ)言：Marvelous /Excellent /Fantastic /Well done/Great?(五)Summing-up（總結(jié)）

Through learning this passage, we have got to know that English is becoming more and more popular all over the world now.So English learning seems important to everyone, especially us students of the new century.With China’s entry into WTO, English will play a more important part in business, in tourism, and even in people’s daily life.So it’s no doubt that everyone should have a good knowledge of English.And I hope everyone in our class can make an effort to learn English well.But on the other hand, it doesn’t mean English is better than Chinese.We must keep it in mind that one’s mother tongue is the most beautiful language in the world.The reason why we learn English is that we should thus be more capable of building up our country.(六)給學(xué)生講解本課的生詞。1.include v.a)contain

1、課后熟讀課文；

2、完成Post-reading Ex.2。

課后反思：本課是閱讀課。英語(yǔ)閱讀教學(xué)是高中教學(xué)的重中之重。許多英語(yǔ)教師對(duì)閱讀訓(xùn)練 也給予了足夠的重視，但是在訓(xùn)練方式上卻存在較多的問(wèn)題。多數(shù)教師過(guò)分注重語(yǔ)法結(jié)構(gòu)的 分析和句子的機(jī)械翻譯而忽視技巧培養(yǎng)。只有在閱讀教學(xué)中教給學(xué)生一些學(xué)習(xí)策略，培養(yǎng)閱 讀技巧，才能讓學(xué)生有可能通過(guò)課外自學(xué)來(lái)擴(kuò)大知識(shí)的攝取量，從而彌補(bǔ)課堂英語(yǔ)閱讀教學(xué) 的不足。由于時(shí)間倉(cāng)促以及學(xué)生口語(yǔ)水平的局限，本課時(shí)在學(xué)生讓學(xué)生討論的環(huán)節(jié)上，氣氛 不夠熱烈，討論時(shí)間不足，今后應(yīng)盡量鼓勵(lì)學(xué)生多開(kāi)口說(shuō)英語(yǔ)，以彌補(bǔ)這方面的缺陷。
