教學步驟

Step 1 Warming up

T：Greet to the class. Before studying the new lesson，lets watch a video recording about a great climber who was climbing a great mountain. And then answer my question.

Step 2 Leading in

T：Boys and girls，do you know what mountain it is ？

Ss：Is it Qomolangma？

T：Yes，thats right. There are so many famous places in the world. Do you want to visit them in the future？（Show them some pictures of the Nile，the Sahara and the Caspian Sea.）

Ss：Yes，we do./Thats for sure.

T：Please try your best to make your dream come true.Today I will lead you to enjoy the beauty of the places.

【設計意圖】課前播放攀登珠穆朗瑪峰的配樂視頻帶領學生進入一種激昂的挑戰(zhàn)境界，引起他們的學習興趣。展示其他世界之最的圖片，為1a做鋪墊。

Step 3 Presentation （Finish the tasks 1a-1c）

T：Lets check the preview of the new words： one student says out the Chinese meanings of the words，the other one spells them. Such two students form a group. （Decide two winners from three or four groups.）

T：All of you did well. Keep trying. In this lesson，we will compare some things with large numbers. Now please try to read these number after me：

135 ；796 ；3，250；13，568，213，000。

（Let the Ss have a discussion about how to sum up the methods of the reading and writing about the numbers. ）

For example： 13 ， 5 6 8 ， 2 1 3 ， 4 7 0

↑ ↑ ↑

billion million thousand

We can read like this： thirteen billion，five hundred and sixty-eight million，two hundred and thirteen thousand，four hundred and seventy.

（Ss read the numbers of Part 1a. The teacher checks the mistakes；then finish Part 1a. Match the places with the facts.Then make sentences such as： The Sahara is about 9，600，000s quare kilometers in size. Then make conversations like this.

S1：How high is Mount Qomolangma？

S2：Its 8848.43 meters high.

T：You have grasped the facts of the four places， now lets find out more characters of them. Listen to the tape and fill in the blanks.

（Ss finish the task of 1b and then sum up the usages of the comparative degree and the superlative degree of adjectives.）

T：Well done！ We must pay attention to the usages：of all...； In the...； than any other ...

Then please recite the jingle to review the three degrees of adjectives.

（Ss口訣：“原級比較形容詞、副詞放在as... as 中間，比較級和than相連，最高級出現在of all...，in...，among...表示范圍的短語前?！盠ook at the big screen and read the changing rules of the three degrees of adjectives and adverbs.）

T：Now please make conversations according to the information of 1b. （Ss make up some conversations in pairs.）

For example：

S1：Whats the deepest lake in the world？

S2：Its the Caspian Sea.

【設計意圖】這四部分教學活動的設計使學生在單詞挑戰(zhàn)，復習語法的活動中，自主探究總結大數的讀法，深入學習形容詞的比較級、最高級，結對練習等學習活動使學生由淺入深、循序漸進地掌握目標語言。

T：I also have some pictures about China. Do you know what they are？

Ss：They are the Great Wall， the Yangtze River，the largest population of China.

T：You are clever enough to answer the questions. Now please listen to the tape and finish Part 2a and 2b. Then read the facts several times and prepare for Part 2c.

（Ss listen to and finish 2a-2c. Check the answers in their own groups，the teacher walks around and gives them help. ）

For example：

S1：Do you know that China has the largest population in the world？

S2：Yes， I do. Its much larger than that of America.

【設計意圖】通過聽說訓練讓學生總結并熟練掌握形容詞的原級、比較級、最高級在本課的拓展用法。比如much，a lot，even集中出現在此環(huán)節(jié)中的形容詞比較級前表示比較的不同程度，最高級出現在one of... 或序數詞后。

（Finish Part 2d.）

T：As we know， every Chinese person is proud of the Great Wall. Today please follow me and have a trip to the Great Wall. （Show them some pictures about it.）

（Ss read the dialogue and finish the following questions：）

.Whats the most popular question when people visit the Great Wall？

.Why did the ancient emperors build the Great Wall？

.Badaling is____ _____ _____（famous） part of the Ming Great Wall？

（After checking the answers，read in pairs and then try to act it out. ）

T：There are some important language points.Now I will give you a task then you can have a discussion and grasp the usages of the phrases and the sentences.

as far as and as far as I know

feel free to do sth.

either and too

There are no other man-made objects as big as this.（=This is the biggest man-made object of all.）

（Ss have a discussion and explain them in detail with the teachers help.）

【設計意圖】將對話問題化，既訓練了學生的思維能力，又加深了學生對對話的理解，接著在小組探究中掌握了對話的語言點和重點句子。

Step 4 Summary

Unit 7 Section A 1a-2d

（Sum up the teaching aims by explain the items of the chart.）

T：Boys and girls，our homeland — China， as one of the four great ancient civilizations，is an old country，full of beauty and fascination. She has 56 ethnic groups， complex and varied terrains，rich and diverse natural resources，long and great history and culture. I think we should be proud of our motherland and our Chinese people. You should work harder and hold on to your dream，I think you can achieve your dream to travel around our country one day.

【設計意圖】師生互動，進一步深化重難點，培養(yǎng)學生的歸納概括能力，形成知識框架。結束語激勵學生為偉大的祖國奮發(fā)圖強，銳意進取。

Step 5 Homework

Write a passage about China. （According to 2a-2d and the pictures below：）

【設計意圖】充分利用教材資源，設計圖例，激發(fā)學生的寫作興趣。再次運用整合本節(jié)課的重點知識，在達到學以致用的教學目的的同時培養(yǎng)學生的民族自豪感，從而實現本節(jié)課的情感教育目標。

教學反思

1.本節(jié)課課型是一節(jié)新授課，設計了一系列的聽說讀寫教學任務，學生在師生互動、生生互動的過程中掌握了重點詞匯，較大數字的表達方法。

2.學生在經過初步感知較大數字讀法及形容詞比較、最高級的拓展用法之后，探究、討論這些問題，達到感知—理解—共鳴—吸收的課堂教學效果。

3.有效地運用多媒體信息技術，實現了網絡與英語課程的整合。事實證明播放恰當的有聲視頻更具有感染力，更能激發(fā)學生的學習興趣。

4.由淺入深地呈現核心句式結構和目標語言，在各種比較中了解了一些有關世界之最和中國之最的地理知識。為了達到學以致用的目的，設計的家庭作業(yè)要求從中國悠久的歷史，龐大的人口數量，著名的長江、黃河、高山、長城等方面寫一篇作文，這項活動既整合了本節(jié)所學內容，又培養(yǎng)了他們的愛國主義情操。

5.各個環(huán)節(jié)的教學都充分調動了學生的學習主動性，啟發(fā)學生思考問題，在小組合作、探究中完成任務，教師適當幫助，盡量不讓一名學生掉隊，使每名學生都成為課堂的主人。

總之，教師要為學生創(chuàng)設生動活潑的語言環(huán)境，把學生吸引到活動中去，激發(fā)他們主動參與學習的欲望。按課堂需要取材，合理地拓展教材、整合教材，把情感態(tài)度與價值觀的教育巧妙地融入教學活動中是我們每節(jié)課備課的一個重要方面。
