教材分析和教材重组演讲稿50字
教材分析本单元的中心话题为海底世界。听说读写活动主要围绕海底植物、海底奇妙景观以及有关大海神话故事展开的。
战狼二演员1. Warming Up 部分以海底生物（包括动物和植物）为话题，主要讨论三个方面的问题：学生所见过的海底生物；在何处见过这些海底生物；学生最喜欢的海底生物。该部分提供了短语和图片启发学生思考讨论。在有条件的学校，教师还可以给学生播放一些有关海底生物的电影或录像。
2. Pre-reading 部分设计了一个读图题，图片内容为：Killer whales are attacking a baleen whale with whalers waiting by in their boat，harpoon at the ready. 由此引入阅读文章的相关背景知识：1. 作者：名叫Clancy的老人(an old man, called Clancy); 2. 职业：捕鲸人(a whaler);
3. 文体: 逸事(anecdotes);
4. 概要: 虎鲸(killer whale)在每年的迁徙过程中帮助捕鲸人捕捉须鲸(baleen whale);
5. 地点; 澳大利亚(Australia);
6. 时间: 20世纪初(at he beginning of the 20th century)。
3. Reading 是一篇以第一人称口吻讲述了一个名叫Old Tom的虎鲸的故事。故事分两部分：第一个故事讲述Old Tom是捕鲸人的好帮手；第二个故事讲述Old Tom是遇难者的救星。故事发生在20世纪初，海上捕鲸和捕鲨没有像现在这样受到限制。学生阅读此文可以了解人类如何利用鲸捕杀鲸的残酷事实，同时可以从文中学到许多描述事物和情景的生动手法。
4. Comprehending 共有3个练习，第一个是两人小组活动，就课文内容进行讨论，重点检测学生对课文深层次的理解；第二个是小组活动，讨论以课文为基础，可以进行适当的拓展，通过讨论让学生进一步明确：动物是人类的朋友。第三个还是小组活动，让学生讨论是否应该关闭捕鲸站并保护鲸。
5. Learning about Language部分首先是词汇训练，通过填空的形式，巩固和运用课文中出现的生词和短语；然后是语法训练，通过用所给词的适当形式填空，复习动词-ing 形式的被动式的用法。
炒山药6. Using Language分为四部分，综合训练听说读写的能力。
第一部分是阅读与讨论。阅读材料以“崭新的生活空间”（A New Dimension of life）为题，用日记的形式记述了作者在海底所见到的奇妙景色。阅读之后设置了四个练习。第一个练习要求学生弄清楚本文描写的顺序；第二个练习要求列入潜泳的刺激和危险；第三个练习操练名词短语，要求学生注意其中小桐树
形容词的用法；第四个练习要求学生对第三题中形容词进行分类并且掌握做定语的形容词的先后位置关系。
第二部分是讨论与写作。通过回顾A New Dimension of life的描写片段，给出表达作者情绪的方式。然后要求学生仿照日记的三、四段写一篇描写某个地方和当地动植物的短文。
第三部分是读、议、听，以听力训练为主。在听之前，首先让学生阅读一个观看鲸鱼的广告并讨论三个问题。接着，让学生听游客与导游之间的三段对话并判断游客的态度。接下来，让学生再听一遍完成表格，填写游客的期望与实际情况。然后重点落在
drifting animals and are usually small, however, they can grow to fairly large size. For example, the jellyfish and the Portugue man-of-war are examples of larger types of zooplankton which are unable to propel themlves effectively and are therefore at the mercy of either wind or current. Nekton is the free swimmer and probably the largest portion of familiar animals found in the ocean belonging to this class. Common fishes, the octopus, whales, eels and squid are all examples of nekton.

II. Pre-reading
What is an anecdote? Why do we pay special attention to some experiences and tell about them? Are they true or fal? Can they be trusted? Why do we lectively ignore other experiences? The are questions of vital importance for people who consider it important to really learn what is fact and truth.
Let's start with a definition:
"Anecdote: a usually short narrative of an interesting, amusing, or biographical incident." The very fact that we tell anecdotes is that we find them interesting and often personal. They are unusual, and are often what we have personally experienced or heard about. We wouldn't notice them or bother telling them if they were the norm, rather than the exception. We u them as reinforcements to shore up our arguments. We u them when we lack proof, IOW, for lack of anything better. We also notice them becau they may reaffirm some cherished idea we have: "Man prefers to believe what he prefers to be true." - Francis Bacon"
We also u them becau they give things a personal touch. They are part of us. Cold facts don抰touch hearts. But cold facts will continue to exist, whether we believe in them or not. They are not changed by what we believe about them.
III. Reading
1. Reading aloud to the recording
Comprehension—understanding what you are reading—is important. To read in thought groups is an easy, yet effective, way of improving reading comprehension. Now turn to page 20 and read aloud to the recording of the text Old Tom the Killer Whale. Pay attention to the thought groups in the ntences while listening and reading aloud.
2.Reading for forms
Read the text again to: cut/ the ntence into thought groups, blacken the predicates, darken the connectives and underline all the uful expressions.
3. Copying and making ntences
