Stentence Structure:B. Vocabulary:C. T ense:D. Text Structure:INTEGRATING SKILLSReading NATURE'S NURSERY: ESTUARIESAs the oceans are the source of life on earth, the estuaries are our planet's nurseries. An estuary is the body of water where a river meets the ocean. Salt water from the ocean and fresh water from the fiver mix together in an estuary. This mixing of fresh and salt water creates a unique environment filled with life of all kinds -- a zone between the land and the sea. Estuaries are the homes of thousands of animals and plants. Many cities and towns are built near estuaries, and a lot of fish is caught in estuaries.Estuaries are great places for nature's young ones. Here, animals can enjoy all the benefits of the oceans without having to face many of the dangers. Tides provide energy for the ecosystems, but estuaries are protected from waves and storms by islands, mud or sand. Nutrients arrive in estuaries from both the land and the ocean. The density of living creatures is higher than in any other habitat on earth. The diversity of life in estuaries is incredible-- birds, fish, marine mammals, shellfish and other species all come here to live, feed and reproduce.Estuaries are also important because they absorb nutrients and pollutants from water coming from inland sources, thus cleaning our water. Unfortunately, this function also makes estuaries very sensitive to environmental pollution. Since estuaries protect animals and plants from storms and floods and prevent erosion, protecting estuaries is very important.Finally, estuaries provide both recreation and education for human beings. Most of us enjoy fishing, swimming and having fun on the beach, and scientists and students have endless opportunities to study a variety of life in the habitat. Estuaries also contribute to the economy through tourism and fishing.T opic Sentence of Paragraph : _____Sentence:estuaries are our planet's nurseries.Topic Sentence of Paragraph : Sentence: EstuariesTopic Sentence of Paragraph: Sentence: Estuaries are also important because they absorb nutrients and pollutants from waterTopic Sentence of Paragraph: Sentence: Estuariesprovide both recreation and education for human beings.1 Why are estuaries such good places for nature's young ones?2 What does density mean in this passage?3 How do estuaries affect the water that passes through them?4 Why are estuaries more sensitive to pollution than other areas?5 Why are estuaries important to human beings?。

高二英语教案：Unit13教案

Unit 13 Water planet Ｉ．单元教学目标II．目标语言III．教材分析与教材重组1．教材分析本单元以Water Planet“水的星球”为话题, 但课文主要谈论的是The water on the planet where the human beings live,“星球（地球）的水”。

通过本单元教学，学生利用所学英语知识，同时联系其他学科所学知识，了解水的特性、化学结构，还了解海水（咸水）的盐度、密度、热容度以及大洋的运动等科学知识。

通过本单元的学习，学生不仅可以了解到英语（科技）说明文的特点和写作手法，还可以体会到英语的实用价值，从而激发学生学习英语的兴趣。

在学习过程中，应通过给学生布置“任务”，如查阅书籍、上网搜索、小组合作来开发学习资源，拓展主题内容，加深相关题材学习。

教师可提前指导学生利用挑好的部分网站辅助学习。

1.1 WARMING UP 通过几个试验来让学生观察并了解水和其他一些物品放在一起时的一些现象和变化，并通过问题引导学生了解水的特性和重要性。

同时还使学生联想所学过的关于地球水污染和保护的知识话题。

此“热身”活动不仅可练习学生的动手、观察和英文表达能力，也为READING的学习做好铺垫。

1.2 LISTENING 是一首关于海洋中的生命的英文诗歌，讲述航海探险中的一个故事，使学生了解人类和海洋的关系。

1.3 SPEAKING 是学生“双人”交际活动。

要求同学阅读几幅描述人类如何使用水的图画，每组同学选择其中一幅，利用所提供问题或自己设计的问题，讨论使用和保护水的重要性。

1.4 PRE-READING 是READING的热身活动。

目的在于练习学生根据主题设计内容和问题的能力，是阅读和写作的基本技能。

要求学生不阅读课文，只看各段的标题，挑出各段的主题并用所给出的结构提出六个问题，然后与同伴或同组的同学回答这些问题，写下答案和各人所知的关于各话题的知识。

这也是利用其他学科如化学、生物等进行学科整合学习型的活动，利于调动学生的积极性和运用其知识储备解决问题。
