Ss：Yes，we do./That’s 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(shè)計意圖】課前播放攀登珠穆朗瑪峰的配樂視頻帶領(lǐng)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）

【設(shè)計意圖】充分利用教材資源，設(shè)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(xiàn)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(shè)計了一系列的聽說讀寫教學任務(wù)，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(shù)字的表達方法。

2.學生在經(jīng)過初步感知較大數(shù)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(shù)，實現(xiàn)了網(wǎng)絡(luò)與英語課程的整合。事實證明播放恰當?shù)挠新曇曨l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(xiàn)核心句式結(jié)構(gòu)和目標語言，在各種比較中了解了一些有關(guān)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(shè)計的家庭作業(yè)要求從中國悠久的歷史，龐大的人口數(shù)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(nèi)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(diào)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(wù)，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(shè)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。
