Unit 3 Under the sea教案設(shè)計
浙江省湖州二中 邵寧寧
1．指導思想與理論依據(jù)
（1） 指導思想
本課題努力將新課程的理念融入教學之中，將語言知識與學生的現(xiàn)實生活緊密聯(lián)系；將課堂教學放在具體的語言情景之中；把聽、說、讀、寫語言技能的訓練綜合運用于課堂教學之中。通過探究法、觀察法和發(fā)現(xiàn)法，讓學生發(fā)揮主觀能動性，改變原有的教師說解、說教的形式，重視知識和結(jié)論形成過程。努力發(fā)揮形成評價的激勵機制，利用兩兩合作、小組活動的方式，激發(fā)學生參與教學的熱情。根據(jù)學生的認知能力和接受程度，設(shè)計了編寫對話和仿效寫作文等任務，使任務具有可操作性，讓學生整堂課都處于新鮮感不斷的亢奮狀態(tài)中，并產(chǎn)生繼續(xù)學習的動力。
總之，本次設(shè)計的宗旨是努力提高課堂教學的實效性，使學生能夠提高語言的實際運用能力，達到最終教學的目的。
（2） 理論依據(jù)
《普通高中英語課程標準》明確提出：“要通過設(shè)計豐富多彩的課內(nèi)外學習活動，使學生在參與交際活動的過程中形成交際策略。”和“教師要引導學生主動學習，幫助他們形成以能力發(fā)展為目的的學習方式，鼓勵學生通過體驗、實踐、討論、合作和探究等方式，發(fā)展聽、說、讀、寫的綜合語言技能�！�
2．教材內(nèi)容分析：
人教版NSEFC M7U3的主題是“Under the sea”，中心話題是海底世界，聽、說、讀、寫活動主要圍繞海底動植物、海底奇妙景觀，以及有關(guān)大海的神話故事展開的。教學內(nèi)容由二篇閱讀，二份聽力，三個話題討論和三個話題延續(xù)性寫作任務組成。
閱讀內(nèi)容是：1、兩起虎鯨軼事（P20-21）
2、一篇有關(guān)海洋見聞和感受的日記（P23）
聽力內(nèi)容是：1、三個觀鯨人對旅行社服務的一些抱怨（P25-27）。
2、記者和鯊魚專家有關(guān)人們對鯊魚的誤解和為什么鯊魚會急劇減少的談話（P65-66）。
話題和寫作內(nèi)容：1、用using language 閱讀中表達感受的詞匯描述過去的難忘經(jīng)歷（P24）。
2、用listening中的抱怨用語在設(shè)置的情境中禮貌抱怨（P27）。
3、用以前學的persuasive writing的表述寫一篇有關(guān)正確對待海洋生物，禁止亂捕的勸戒性文章。
我把整個單元整合為七個課時：
第一課時是詞匯和熱身部分。通過提供直觀、感性的圖片或素材，讓學生正確地讀、記字詞的音、意和學習部分用法，同時提供情境讓學生運用新字詞完成短文。
第二課時是Using language 中的閱讀：A new dimension of life (P23): 首先考慮到第一課時與此部分內(nèi)容聯(lián)系密切，環(huán)環(huán)相扣；其次通過掌握單詞和詞匯，學生必然對看到的喜歡的和害怕的海洋動植物有一種很想“說”的欲望，而此課時的內(nèi)容恰恰是表達對這次海洋之旅的感想，可謂首尾呼應，相得益彰。本課時的目標旨在：
1、讓學生正確地說出部分海洋生物的名稱。
2、讓學生學會用wise-looking, brain-shaped, red-spotted, blue-striped 等復合形容詞修飾看到的動植物。
3、讓學生意識到多個形容詞修飾名詞時是有順序的。
4、讓學生找出、體會表達感受的字詞，并運用到自己的經(jīng)歷中去。
第三課時是課文（P25-27）的讀、聽、說、寫活動，承接第二課時的話題觀看海洋生物：由讀船上觀鯨的旅游廣告開始，聽三段旅客抱怨的聽力，再進入到禮貌抱怨用語的學習和運用這些用語到設(shè)置的情境中。
第四課時是一篇內(nèi)容涉及虎鯨幫助人類捕鯨和救助落水者的兩起逸事（P20-21）。作者以第一人稱的口吻，講述了一個名叫Old Tom的虎鯨的故事。故事一共分兩部分：第一個故事講述Old Tom是捉鯨人的好幫手；第二個故事講述了Old Tom是遇難者的救星。本教學目標旨在：
1、是學生能簡單介紹虎鯨的基本信息。
2、是學生會利用關(guān)鍵字詞復述故事。
3、是讓學生正確認識到人類與海洋生物的關(guān)系。
第五課時是language points。
第六課時是V+ing的被動形式的復習和鞏固以及運用。目標是學生能在教師設(shè)置的情境或圖片中正確的運用like/love/ hate/ fear/ enjoy/ imagine/ admit/ stand/ mind…等動詞后面跟被動形式和with/ have/ see/ find/ witness/ feel…+賓語+being done 做賓補的形式。
第七課時是聽、說、寫的整合課內(nèi)容：聽采訪鯊魚專家的聽力材料（P65-66），說人們對待海洋生物的態(tài)度和如何制止濫捕濫殺現(xiàn)象，寫一封信給當?shù)卣畞砗侠砝煤Ｑ笊镔Y源。
3．學情分析
高二學生這個新鮮話題普遍很感興趣，積極性也比較高，但大部分學生對新學的單詞詞匯還是比較生疏，進行交際英語的能力還是比較薄弱的，因此教師可以利用豐富多彩的圖片資源，在任務型教學下完成本課題的學習。班級里的學生水平參差不齊，有些差距還是比較大的，因此在教學過程中，布置的任務要兼顧各個層次的學生，使他們通過聽、說、讀、寫都有所獲。
4．三維目標
知識目標
（1） 掌握本單元教學目的和要求中的單詞和詞匯。如：anecdote, annual, witness, accommodation, shore, yell, pack, flee, drag, depth, lip, tongue, abandon, relationship, rent, seaside, net, dimension, reflect, pure, magic, beauty, cell, aware, vivid, poisonous, cave, narrow, sharp, tasty, scare, shallow, entry, awesome, seal, pension, pensioner, ahead of, in the meantime, help out, be/ become aware of, upside down, be scared to death etc。
（2） 幫助學生更多地了解海洋/海底世界。
（3） 復習動詞V-ing形式的被動式。
能力目標
（1） 提高學生閱讀能力和賞析水平。
（2） 在寫作中學會表達責備、抱怨和要求賠償。
情感目標
培養(yǎng)學生熱愛和保護海洋生物的愛心。
教學重點
（1）更多了解海洋海底生物。
（2）樹立正確的觀念“海洋生物和人們是朋友”并要熱愛和保護它們。
教學難點
（1） 鞏固動詞V-ing形式的被動式的用法。
（2） 在寫作中學會表達責備、抱怨和要求賠償。
教學方法
（1） 任務型教學。
（2） 合作型教學。

完成式 (not) having done (not) having been done
3．動詞 -ing的被動式的句法功能。
（1） 做主語。如：So being killed by sharks was a common thing.
（2） 做賓語，用在介詞后或需要帶-ing 形式作賓語的動詞后。如：
George didn't like being kept waiting.
He was terrified of being abandoned by us.
Do you remember having been taken to Beijing at the age of ten?
（3） 做表語。如：
What worried the child most was his not being allowed to visit his mother in the hospital.
（4）做定語。如：
The problem being discussed is of great importance.
（5）做狀語。如：

（6） 做補足語。如：
As we drew closer, I could see a whale being attacked by a pack of six other killers.
When we approached him, I saw James being held up in the water by Old Tom.
[注意]
（1）V-ing 形式被動式主要在句子中作狀語、賓語補足語和定語。但V-ing 形式的完成被動式，一般在句中作狀語（偶爾作非限定定語），不作其它成分。
They don’t like ____the design of the new bridge _being built__（正在建造的橋的設(shè)計）
Not having been completed, the museum can’t be visited yet. (由于沒有完工…）
（2）V-ing 形式的被動式邏輯主語（即動作的承受者）如果也是主句的主語，就不需要出示出來，但是如果邏輯主語不是主句的主語，就得把V-ing 形式自己的主語表示出來。如：
The whole classroom having been cleaned, the students went home happily.
（3）在want，need，deserve，require，repay，bear，take等動詞及形容詞worth后，習慣用動詞-ing的主動形式表示被動意義，相當于“to be done"。如：
The house wants cleaning．這房屋需要打掃。
My watch needs repairing．我的手表需要修理。
The way deserves mentioning．這個方法值得一提。
These young trees will require looking after carefully．這些小樹需要細心照顧。

二、 參考資料
1. Killer Whales
Common name: Killer Whale
Scientific name: Orcinus orca
Size:
Females can reach lengths up to 24 feet and weigh between 3,000 to 8,000 lb. Males can reach lengths up to 27 feet and can weigh up to 12,000 lb. Calves are about 8 feet long and 300 to 400 pounds at birth.
Where are they found?
From the North Pole to the South Pole from the Indian Ocean to the Atlantic, killer whales are found in all oceans of the world.
What do they eat?
How do you get a name like "killer whale?" Killer whales are one of the top predators in the sea. As a group, killer whales are known to eat fish, squid, seals, sea lions, penguins, even other whales.
But, keep in mind, it would be difficult for a killer whale off the coast of California to eat a penguin. Killer whales eat the food (or prey) that's available to them. For example, a killer whale that lives in the northern Pacific can hunt harbor seals, California sea lions, and a variety of fish. A killer whale in the Antarctic could find Weddell seals, leopard seals, and penguins!
Researchers studying killer whales in the Pacific Northwest have found that some pods feed primarily on fish and others seem to prefer marine mammals.
A killer whales uses its sharp teeth to catch its prey. Killer Whales are toothed whales
Killer Whale Highlights:
Scientists have determined that killer whales can live a maximum of 35 years. How? By looking at a cross-section of a killer whale's tooth. Killer whales, like other marine mammals, produce a periodic growth layer on the teeth. By counting these layers, scientists can estimate the animal's age.
You can tell an adult male from an adult female by the shape of their dorsal fin. This is a male (photo right), how do we know? A male's fin is very tall (up to 6 feet tall) and triangular shaped. A female is shorter (3 feet) and curves back toward the dorsal fin (see the picture of the mother/calf above.)
2. The earth’s oceans can reach depths of up to 11,000 meters. That is deep enough to cover Mt. Qomolangma! The oceans are incredibly large and contain several different habitats. To make it easier to describe the various parts of the oceans, marine scientists usually divide the oceans into five zones. Each zone is different mainly as a result of how much sunlight reaches it.
Most of the life in the ocean can be found in the first zone, which begins at the surface and goes down about 200 meters. Because there is sunlight at this level, plants are able to grow. Marine animals such as dolphins, sharks, sea turtles and sea lions, and of course a variety of fish, live in the sunlit part of the ocean. It is difficult to hide from other animals in this area.
The second zone starts at 200 meters and goes down to about 1,000 meters. Some sunlight can reach this level, but it is not enough for plants to grow. Because this zone is relatively dark, many of the creatures that live here are able to make light with their body. The light from these animals makes the water look like a sky with moving stars in it.
The third zone of the ocean is dark. This place, about 3,000 meters deep, may not seem a likely habitat, but there are more creatures here than one might think. Most of the animals that live here are black or red because of the lack of light.
Below 4,000 meters, the temperature is near freezing and there is no light at all. In fact, the zone is so dark and empty that scientists named this zone after the Greek word for “no bottom”. There is not much life to be found in this cold and unpleasant part of the ocean, but some small creatures still manage to survive here despite the high water pressure.
The very deepest part of the ocean is found 2,000 meters further down. At this depth, the water pressure is extremely high and life is very difficult for the few creatures that live here. Compared to the other zones, this one has very little life. Since there is no light here, some of the animals do not have eyes.
Next time you look at the ocean from the beach or on a map, remember that what you are seeing is only the surface - only the beginning of the large and varied adventure.
