[教案]人教修订版高三英语Unit 2 Crossing Limits
grammar 教案
人教修订版高三英语unit2Crossing Limits ( grammar) 教案
一、教学目标
通过本章学习，使学生了解谓语的概念、用法，从而减少学生在使用中的
错误。
二、教学重点和难点
在谓语的结构中，某些实义动词兼作连系动词的用法；时态、语态及语
气。
三、教学方法Teacher1．What is the predicate?
First analyse the following sentences.
A．Tom wrote a letter this morning.
B．She is an honest girl.
在B 句中，我们把”she”称为主语，把”is an honest girl”称为谓语部分，只
说”她”，不知她是谁，她怎样了；而只说是个诚实的姑娘，又不知谁是个诚
实的姑娘，这与A 句是一样的。
2．The predicate must contain a finite verb. And we call it the predicate verb. 3．Commonly a predicate must not have more than one finite verb, unless they are
co-ordinated ones. In the sentence, Mrs Green is the subject, went, bought and visited are co-ordinated predicates.
4．中国学生常见的错误之一是在一个句子中，用数个动词，但又没能按规
则使它们成为并列关系。
Unit 2 Crossing limits一、教学内容分析本单元的中心话题是“探索世界”内容涉及人类如何超越极限、海上航行、郑和下西洋、人类攀登珠穆朗玛峰等，帮助学生了解人类在探索世界的过程中如何顽强地克服困难甚至超越极限。
语言技能和语言知识都是围绕这个主题设计的。
“热身”（Warming up）部分由四幅图片和四个问题组成。
要讨论这四个问题学生必须了解郑和、克里斯托弗·哥伦布、詹姆斯·库克和艾贝尔·塔斯曼这四个人物的事迹，他们都为“人类探索世界”做出过巨大的贡献。
在了解人物主要事迹的基础上，学生可以总结出四位人物的共同特点：他们都是探索世界的航海家，从而回答第一个问题。
对于高三的学生来说，回答第二个问题应该很容易，可以复习七大洲的名字。
对于第三、四个问题，学生在讨论的基础上也可以提供部分的答案。
这两个问题的讨论有助于接下来做听力练习。
“听力”部分是一个记者和一个教授之间关于人类过去和现在探索未知世界所可能遇到的困难与挑战的对话。
在听之前让学生讨论练习1的三个问题有助于学生对对话内容的预测，熟悉对话中出现的词汇和表达方法，从而降低听的难度。
练习2让学生比较过去和现在在交际和交通上的重要差异，可以让学生了解过去探索世界的巨大困难。
在录音内容中可以直接得到有关这两方面的情况。
练习3中所设计的几个问题也是围绕人类过去和现在探索未知世界所可能遇到的困难与挑战的主题所设计的，主要训练学生把握文段细节的能力。
“口语”（Speaking）部分要求学生对形势作出分析判断，然后提出相应的对策和作出决定。
在这一部分，学生阅读相关材料并提出他们自己的观点。
在这一过程中学生可以了解我们该如何探索世界，以及如何对待我们探索世界时候所发现的地方、空间、文物等，对于培养他们探索未知世界的热情和克服困难的决心有促进作用。
“读前”（Pre-reading）部分的第一个问题让学生了解“丝绸之路”的有关情况，为第二个问题做好铺垫，那就是在中国陆路已经和其他洲建立联系的情况下，为何还要开辟更长的水路联系？这有何重要意义？从而为我国历史上的那些航海家探索“海上丝绸之路”找到依据。
Unit 2 Crossing limitsⅠ.Brief Statements Based on the UnitThe topic we will talk about in this unit is about exploring the world.First,four famous voyage explorers in the world,including Zheng He in China,James Cook in England,Christopher Columbus in Spain and Abel Tasman in Holland are briefly introduced.They played an important role in the history of the world’s voyage.Second,we’ll learn two passages:one is about Reading out across the ocean,which tells us the contacts between China and Africa.The other is about Going high:the pioneers of the third pole,which describes to us that some people from all over the world climbed Mount Qomolangma.These will provide some information for us about exploring the world,and at the same time make us feel the explore rs’ hardship,puzzles,success and greatness.In addition,the students can learn some useful language points through the materials provided in this unit,which are very helpful for the students to build up vocabulary about exploration.In the grammar part,the students will review the Predicate by doing some exercises,especially how to use the proper forms of given verbs to complete the passages.At last,teacher will help the students finish the task of writing,that is,how to write a persuasive essay.In a word,the students’ integrating skills can be well developed through learning.Ⅱ.Teaching Goals1.Talk about exploring the world.2.Practise judging situations and making decisions.3.Review the Predicate.4.Write a persuasive essay.Ⅲ.Background Information1.Columbus’s VoyagesColumbus made four voyages to the west between 1492 and 1504 in his vain search for a sea route to Asia.The mystery of why he failed to find it haunted （萦绕在心头） him and filled him with sadness.Wherever he went—to Cuba,Puerto,Rico,Jamaica,South America,Panama,down the coast of Central America—it was always the same story.Instead of golden palaces,there were grass huts and palm-leaf tents.Instead of silk-robbed merchant princes,he found “Indians” who did not have so much as a shirt on their backs.When Columbus explored the West Indies in 1493,he heard tales of a fierce Indian tribe（部落） who really devoured（吞噬） its defeated enemies after a battle.This people was called by many names in the area,including Calina,Canima,Carib,Cariba and Caniba.Columbus recorded the name of the American natives as Canibales in Spanish,a word which came to refer,within a few years,to any eater of human flesh.In the similar fashion,the word Caribbean, a title for the sea as well as for the region,came into English.At times Columbus became reconciled（意见一致） to the truth that this new land was not China,not Japan,not the Spice Islands.He seemed to accept it as a part of the earth that the geographers to Europe had never heard of before.It was another world—and he called it exactly that—but Columbus also insisted until he died that the land he had reached was an unknown part of Asia.2.James CookJames Cook was a great explorer,who was sent by England to explore the Pacific Ocean.Before he started exploring,maps of the Pacific Ocean were almost empty.He visited hundreds of islands across the Pacific Ocean and put them in the correct places on the map.He made maps of the coastlines ofAustralia and New Zealand.James Cook was born in England in 1728.His parents were poor farm workers.When James was 18,he found a job on a coast ship.He worked on the ship until he was 27 years old,and then he joined the navy.He fought in eastern coast of Canada in a war against France,and he mapped some of the eastern coast of Canada.In 1768 King George Ⅲ made him Captain of a ship and sent him to the Pacific.He was gone for nearly three years.When he returned,he was regarded as a national hero.He started his third voyage in 1776.On this trip he visited Hawaii.He was the first European to set foot on this beautiful island.Then he mapped the western coast of North America.After that he returned to Hawaii.Unfortunately there was some trouble between the Hawaiians and the white men and they started fighting.In the end Captain Cook was killed in a clash with the locals.Ⅳ.Teaching Time:Five
