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+序數詞”用來表示編號，強調“第??”

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

“ a+序數詞”強調“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是現在分詞短語做方式狀語。現在份詞作狀語，表示主語正在進行的另一動作，對謂語表示的主要動作加以修飾和陪襯，分詞動作與謂語動作都必須是同一主語進行的，它可以表示時間、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.大多數人講英語的國家有42個還多。

more than意為“超過，不僅僅”，相當于over, not only。例如：

（1）There ar more than 2,000 students in our school.我們學校有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.她不僅僅是個老師，她像母親一樣愛護我們。

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

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

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

majority是句詞，意為“多數，大多數，半數以上”。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。

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

（3）The majority were/was against the plan.多數人不贊成這個計劃。

4.However, the number of people who learn English as a foreign language is more than 750 million.然而，把英語作為外語來學的人有7億5千萬。

the number of/a number of 辨析

the number of意為“??的數目，??的號碼”作主語時，謂語動詞用單數；a number of意為“一些，許多”，作定語，修飾復數名詞，作主語時謂語動詞用復數。例如：

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

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

⑴.1et Ss read through the exercise and make sure what they will to do.⑵.get Ss to finish the exercise in page 11 individually, and check the answers in the class.2.Grammar---Direct Speech and Indirect Speech 祈使句的間接引語

祈使句的間接引語通常采用含有祈使意義的“及物動詞（ask, tell, order, advise等）+ 賓語+不定式”這一結構將原來的話語表達出來，否定的祈使句在轉換時候在不定式前加not,引述動詞可以根據語意選用。

“ Please give me some oranges.”---He asked me to give him some oranges.“ Don’t stop reading,” the teacher said---The teacher told his students not to stop reading.“ Be careful next time,” Mother said.---Mother warned her child to be careful the next time.“ Please don’t open the window, ” Jack said.---Jack asked me not to open the window.He said, “Get everything ready in two hours.”---He ordered us(them)to get everything ready in two hours.3.practice

2．理解牛頓第二定律的內容，知道定律的確切含義；

3．知道得到牛頓第二定律的實驗過程。

二、能力目標

培養學生的實驗能力、分析能力和解決問題的能力。

三、德育目標

使學生知道物理中的一種研究問題的方法——控制變量法

教學重點

1．牛頓第二定律的實驗過程；

2．牛頓第二定律。

教學難點

牛頓第二定律的意義。

教學方法

實驗法、講授法、歸納法

教學用具

兩輛質量相同的小車，光滑的水平板（一端帶有定滑輪）；砝碼（一盒），細繩、夾子 課時安排 2課時

教學過程

一、導入新課

1．提問：什么是物體運動狀態的改變？物體運動狀態發生改變的原因是什么？

2．引入新課：

通過上節課的學習，我們已知道：物體運動狀態改變時產生加速度，而產生的加速度又和物體的質量及所受力的大小有關，那么：加速度跟物體所受力的大小及物體質量之間有什么關系呢？本節課我們就來研究這個問題。

二、新課教學

（一）用投影片出示本節課的學習目標：

1．理解加速度與力的關系；

2．理解加速度與質量的關系

3．理解牛頓第二定律的內容。

（二）學習目標完成過程：

1、加速度和力的關系：

（1）用投影片出示本節課所用的實驗裝置，教師進行講解：圖中是兩輛質量相同的小車，放在光滑的水平板上，小車的前端各系上細繩，繩的另一端跨過定滑輪各掛一個小盤，盤里放有數量不等的砝碼，使兩輛小車在不同的拉力下做勻加速運動。

（2）對本次實驗中說明的兩個問題

a：砝碼跟小車相比質量較小，細繩對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繩，以同時控控制兩輛小車。

（3）實驗的做法：

a：在兩砝碼盤中放不同數量的砝碼，以使兩小車所受的拉力不同。

高考資源網 2006精品資料系列

b：打開夾子，讓兩輛小車同時從靜止開始運動，一段時間后關上夾子，讓它們同時停下來。

（4）需觀察的現象，觀察兩輛車在相等的時間里，所發生的位移的大小。（實驗現象：所受拉力大的那輛小車，位移大）

（5）分析推理：

a：由公式s1?at2得到在時間t一定時，位移s和加速度a成正比；

2b：由實驗現象得到：小車的位移與他們所受的拉力成正比。

c：推理得到結論：對質量相同的物體，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：

a．據得到：要使物體在短時間內速度的改變很大，即加速度很大，就必須給物體提供。

b．競賽用的小汽車，要求起動后幾秒鐘內速度由零達到60m/s以上，他們為什么要裝備功率很大的發動機？

2：加速度和質量的關系：

（1）實驗裝置同上；

（2）說明與前次實驗的不同。

前一次實驗中，我們是保持小車質量不變，而改變小車所受力的大小，來研究加速度和力之間的關系的。

本次實驗是使兩輛小車所受拉力相同，而在一輛小車上加放砝碼的，以增大質量，研究加速度和質量之間關系的。

（3）實驗現象：

在相同的時間里，質量小的那輛小車的位移大。

（4）分析推理，得到結論：

在相同的力作用下，物體的加速度跟物體的質量成反比，即

a1/a2=m2/m1或a∝m3：牛頓第二運動定律

（1）綜合上述實驗中得到的兩個關系，得到下述結論：

物體的加速度跟作用力成正比，跟物體的質量成反比，且加速度的方向跟引起這個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：如果每個物理量都采用國際單位，k＝1；

高考資源網 2006精品資料系列

b：力的單位（牛頓）的定義：使質量為1千克的物體產生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力作用的情況，當物體受到幾個力作用時，上述關系可推廣為：

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的瞬時對應關系

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：力隨著時間改變，加速度也隨著時間改變。

d：力停止作用，加速度也隨即消失。

4：例題分析（課本例題）

（1）學生閱讀例題內容

（2）分析：

??質量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，也可以用計算法求解。

（3）用投影片展示解題過程：

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

F1x?F1xcos60o,F2y?F2sin60o

F2的兩個分力為：F2xo?F2cos60o,F2y?F2sin60

F1y和F2y大小相等，方向相反，相互抵消，F1x和F2x的方向相同，所以：

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

已知合力F合和質量m，據F合＝ma，即可求得：

10Na?F合??5m/s2

2kg

三：小結

1：本節課的研究方法——控制變量法

2：牛頓第二運動定律確定了a和F之間的大小關系，也確定的a和F的方向關系

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

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。英語閱讀教學是高中教學的重中之重。許多英語教師對閱讀訓練 也給予了足夠的重視，但是在訓練方式上卻存在較多的問題。多數教師過分注重語法結構的 分析和句子的機械翻譯而忽視技巧培養。只有在閱讀教學中教給學生一些學習策略，培養閱 讀技巧，才能讓學生有可能通過課外自學來擴大知識的攝取量，從而彌補課堂英語閱讀教學 的不足。由于時間倉促以及學生口語水平的局限，本課時在學生讓學生討論的環節上，氣氛 不夠熱烈，討論時間不足，今后應盡量鼓勵學生多開口說英語，以彌補這方面的缺陷。
