2019-2020年高中英语（人教大纲）第三册：Unit2 Crossing limits(第一课时).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 worlds voyage.Second,well 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 explorers 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 plete 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.Teaching Goals1.Talk about exploring the world.2.Practise judging situations and making decisions.3.Review the Predicate.4.Write a persuasive essay.Background Information1.Columbuss 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 wentto Cuba,Puerto,Rico,Jamaica,South America,Panama,down the coast of Central Americait 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 worldand he called it exactly thatbut 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 of Australia 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 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.Teaching Time:Five
