8、，也是學(xué)生最感興趣的話題一一海底動物和植物，要求學(xué)生以互相交流的方式更多地了解海底世界。緊接著是小組活動，要求學(xué)生將的海洋動植物列表歸納，并談?wù)撟约鹤钕矏鄣暮Ｑ髣游锘蛑参?。這一局部的設(shè)計為下一步的課文學(xué)習(xí)以與后邊的聽、說、讀、寫在容方面打下了伏筆。1.2 Pre-reading是Reading文圖并茂的容簡介。"虎鯨幫助捕鯨人在每年須鯨遷徙時捕捉 須鯨"的奇聞軼事會立刻激起學(xué)生的閱讀興趣。1.3 Reading是一篇題為"Old Tom the Killer Whale "的故事，其中包括兩篇關(guān)于虎鯨的奇聞軼事。第一篇講虎鯨如何幫助捕鯨人捕捉須鯨，過程奇

9、妙有趣。第二篇講虎鯨如何從鯊魚群中救出捕鯨人， 情節(jié)驚險感人。學(xué)生通過對課文的閱讀理解，會由衷地感謝這些可愛的海洋動物對人類忠實的幫助和巨大的奉獻，同時習(xí)得閱讀故事的技能。1.4 Comprehending設(shè)計了根據(jù)課文容描述Old Tom和捕鯨人的關(guān)系，旨在引導(dǎo)學(xué)生在閱讀理解的根底上進展再創(chuàng)造。第二題根據(jù)課文答復(fù)以下問題，其目的是評價學(xué)生對文章的理解程度。第三項是小組討論，中心論題一一你是否同意禁止捕鯨一一直擊本單元思想容主題一一環(huán)境和動物保護。整個活動設(shè)計梯次清楚，思想教育意義和語言學(xué)習(xí)意義兩條線共同 逐步深入，以到達閱讀理解的最正確效果。1.5 Learning about Langua

10、ge分為詞匯和語法兩項。 詞匯局部幫助學(xué)生學(xué)習(xí)用適當(dāng)?shù)男问?和意義使用詞匯和短語，旨在培養(yǎng)學(xué)生運用英語詞匯和短語的能力。語法工程是復(fù)習(xí)動詞-ing形式的被動語態(tài)。要求學(xué)生用正確的-ing形式完成單句填空和補全句子來操練這一語法 工程。-ing形式的被動語態(tài)在語法學(xué)習(xí)中是個難點，教師可以在此根底上做些拓展性和穩(wěn)固性的練習(xí)設(shè)計。1.6 Using Language是一個綜合性學(xué)習(xí)工程，包括"閱讀與討論"、"討論與寫作"、"說話與寫作?！伴喿x與討論的主體是一篇與海底動植物相處的感受的日記，其后設(shè)計了四個活動環(huán)節(jié)：速讀選擇信息；細(xì)節(jié)列表；詞匯學(xué)習(xí)；語法

12、務(wù)是本單元寫作練習(xí)的主題：對某事或某人以禮貌的方式責(zé)備和抱怨。該局部提供了表示“責(zé)備和抱怨的習(xí)慣用語和三種情境，要求學(xué)生運用所給的詞語先進展對話練習(xí)，然后再把對話容寫下來。這種寫作練習(xí)設(shè)計能使學(xué)生體會到語言的鮮活、生動和實用，有利于發(fā)揮他們的寫作積極性。2. 教材重組2.1 Pre-reading, Reading, Comprehending 是一個整體，而第一局部 Warming Up 的話題容 又與Reading 致，因此將這幾局部整合在一起，設(shè)計成一節(jié)“閱讀課。2.2 Learning about Language中的兩項活動(詞匯和語法)和 Workbook中的 USING WORD

53、dogs, I think they are the most typical ani mals that help out huma ns in hunting. Upon meeting the quarries, they are very excited and listen to their masters very well to hunt for them. If there is a group of dogs, they may work together till they help the master catch the quarries. Then they will

54、 be very happy and come back to the master to report their success. That' very in terest ing. And if their master is in dan ger, they will rush up to rescue him. There are many moving stories of this kind.Sd: Yes. After readi ng the text, we can leann more about the relati on ship betwee n huma

55、ns and ani mals. Huma ns and ani mals should depe nd on each other and be kind to each other.

Many people are trying to prote

56、ct them from being hunted. The last whaling station in Australia closed in 1978. But some countries oppose the ban. And there are still people who hunt whales. What 'your opinion? Are you for or against the banning whaling? Consider the problem carefully and we'll have a discussion tomorrow.
