Unit 3 Under the sea教案设计
浙江省湖州二中 邵宁宁
1．指导思想与理论依据
（1） 指导思想
本课题努力将新课程的理念融入教学之中，将语言知识与学生的现实生活紧密联系；将课堂教学放在具体的语言情景之中；把听、说、读、写语言技能的训练综合运用于课堂教学之中。通过探究法、观察法和发现法，让学生发挥主观能动性，改变原有的教师说解、说教的形式，重视知识和结论形成过程。努力发挥形成评价的激励机制，利用两两合作、小组活动的方式，激发学生参与教学的热情。根据学生的认知能力和接受程度，设计了编写对话和仿效写作文等任务，使任务具有可操作性，让学生整堂课都处于新鲜感不断的亢奋状态中，并产生继续学习的动力。
总之，本次设计的宗旨是努力提高课堂教学的实效性，使学生能够提高语言的实际运用能力，达到最终教学的目的。
（2） 理论依据
《普通高中英语课程标准》明确提出：“要通过设计丰富多彩的课内外学习活动，使学生在参与交际活动的过程中形成交际策略。”和“教师要引导学生主动学习，帮助他们形成以能力发展为目的的学习方式，鼓励学生通过体验、实践、讨论、合作和探究等方式，发展听、说、读、写的综合语言技能。”
2．教材内容分析：
人教版NSEFC M7U3的主题是“Under the sea”，中心话题是海底世界，听、说、读、写活动主要围绕海底动植物、海底奇妙景观，以及有关大海的神话故事展开的。教学内容由二篇阅读，二份听力，三个话题讨论和三个话题延续性写作任务组成。
阅读内容是：1、两起虎鲸轶事（P20-21）
2、一篇有关海洋见闻和感受的日记（P23）
听力内容是：1、三个观鲸人对旅行社服务的一些抱怨（P25-27）。
2、记者和鲨鱼专家有关人们对鲨鱼的误解和为什么鲨鱼会急剧减少的谈话（P65-66）。
话题和写作内容：1、用using language 阅读中表达感受的词汇描述过去的难忘经历（P24）。
2、用listening中的抱怨用语在设置的情境中礼貌抱怨（P27）。
3、用以前学的persuasive writing的表述写一篇有关正确对待海洋生物，禁止乱捕的劝戒性文章。
我把整个单元整合为七个课时：
第一课时是词汇和热身部分。通过提供直观、感性的图片或素材，让学生正确地读、记字词的音、意和学习部分用法，同时提供情境让学生运用新字词完成短文。
第二课时是Using language 中的阅读：A new dimension of life (P23): 首先考虑到第一课时与此部分内容联系密切，环环相扣；其次通过掌握单词和词汇，学生必然对看到的喜欢的和害怕的海洋动植物有一种很想“说”的欲望，而此课时的内容恰恰是表达对这次海洋之旅的感想，可谓首尾呼应，相得益彰。本课时的目标旨在：
1、让学生正确地说出部分海洋生物的名称。
2、让学生学会用wise-looking, brain-shaped, red-spotted, blue-striped 等复合形容词修饰看到的动植物。
3、让学生意识到多个形容词修饰名词时是有顺序的。
4、让学生找出、体会表达感受的字词，并运用到自己的经历中去。
第三课时是课文（P25-27）的读、听、说、写活动，承接第二课时的话题观看海洋生物：由读船上观鲸的旅游广告开始，听三段旅客抱怨的听力，再进入到礼貌抱怨用语的学习和运用这些用语到设置的情境中。
第四课时是一篇内容涉及虎鲸帮助人类捕鲸和救助落水者的两起逸事（P20-21）。作者以第一人称的口吻，讲述了一个名叫Old Tom的虎鲸的故事。故事一共分两部分：第一个故事讲述Old Tom是捉鲸人的好帮手；第二个故事讲述了Old Tom是遇难者的救星。本教学目标旨在：
1、是学生能简单介绍虎鲸的基本信息。
2、是学生会利用关键字词复述故事。
3、是让学生正确认识到人类与海洋生物的关系。
第五课时是language points。
第六课时是V+ing的被动形式的复习和巩固以及运用。目标是学生能在教师设置的情境或图片中正确的运用like/love/ hate/ fear/ enjoy/ imagine/ admit/ stand/ mind…等动词后面跟被动形式和with/ have/ see/ find/ witness/ feel…+宾语+being done 做宾补的形式。
第七课时是听、说、写的整合课内容：听采访鲨鱼专家的听力材料（P65-66），说人们对待海洋生物的态度和如何制止滥捕滥杀现象，写一封信给当地政府来合理利用海洋生物资源。
3．学情分析
高二学生这个新鲜话题普遍很感兴趣，积极性也比较高，但大部分学生对新学的单词词汇还是比较生疏，进行交际英语的能力还是比较薄弱的，因此教师可以利用丰富多彩的图片资源，在任务型教学下完成本课题的学习。班级里的学生水平参差不齐，有些差距还是比较大的，因此在教学过程中，布置的任务要兼顾各个层次的学生，使他们通过听、说、读、写都有所获。
4．三维目标

（2） 帮助学生更多地了解海洋/海底世界。
（3） 复习动词V-ing形式的被动式。
能力目标

（2） 在写作中学会表达责备、抱怨和要求赔偿。

Next, ask students to pay attention to the underlined words and lead into the topic-“V-ing”/ “being done”.
Step2. Grammar Learning
1．现在分词（ing-形式）的构成。
V-ing 形式由 “do＋ing” 构成，其否定形式是 “not doing”, V-ing 可以带宾语或状语构成 V-ing 短语，
没有人称和数的变化，但有时态和语态的变化。
2．动词-ing 形式的被动式分一般式和完成式：
（1） 一般式：表示这个被动的动作正在进行或与谓语表示的动作同时发生。
（2） 完成式：强调这个被动的动作在谓语动词所表示的动作之前完成。
语态
时态 主动语态 被动语态
一般式 (not) doing (not) being done
完成式 (not) having done (not) having been done
3．动词 -ing的被动式的句法功能。
（1） 做主语。如：So being killed by sharks was a common thing.
（2） 做宾语，用在介词后或需要带-ing 形式作宾语的动词后。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） 做表语。如：
What worried the child most was his not being allowed to visit his mother in the hospital.
（4）做定语。如：
The problem being discussed is of great importance.
（5）做状语。如：
Having been shown around the library, we were taken to see the lab.
（6） 做补足语。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 形式被动式主要在句子中作状语、宾语补足语和定语。但V-ing 形式的完成被动式，一般在句中作状语（偶尔作非限定定语），不作其它成分。
They don’t like ____the design of the new bridge _being built__（正在建造的桥的设计）
Not having been completed, the museum can’t be visited yet. (由于没有完工…）
（2）V-ing 形式的被动式逻辑主语（即动作的承受者）如果也是主句的主语，就不需要出示出来，但是如果逻辑主语不是主句的主语，就得把V-ing 形式自己的主语表示出来。如：
The whole classroom having been cleaned, the students went home happily.
（3）在want，need，deserve，require，repay，bear，take等动词及形容词worth后，习惯用动词-ing的主动形式表示被动意义，相当于“to be done"。如：
The house wants cleaning．这房屋需要打扫。
My watch needs repairing．我的手表需要修理。
The way deserves mentioning．这个方法值得一提。
These young trees will require looking after carefully．这些小树需要细心照顾。

二、 参考资料
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.
