Step2 Revision Check the homework exercises.Step 3 PresentationPresent the students a map of the world and tell them “Today we are going to learn a new unit “Sailing the oceans”. Then ask them to turn to page 11 and give them a few minutes to have a discussion. Step 4 DiscussionIn pairs discuss the questions on page11.This discussion is intended for students to explore the difference between a navigator and an explorer. This difference is important to establish because it encourages students to appreciate shades of meaning in the definitions f words and also because it establishes the idea of categories.After a few minutes, ask some pairs to speak out their result of the discussion. Then sum up and check the answers.A navigator explores new routes across the sea.An explorer discovers new places on land.A navigator is somebody who finds the position and plots the course of a ship, an aircraft, a car, etc, using maps and instruments. An explorer is somebody who travels into or through a place in order to learn about it. Very often navigators are also explorers.In history there are 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.In this unit well talk about Zheng He, James Cook and some other explorers like Marco Polo and Captain Bligh.Step 5 Pre-speakingAsk the students if they want to know some famous navigators and explorers. Then present them some pictures and some related information about them.About Zheng He.About Marco PoloAbout James CookAbout Ferdinand Magellan Step 6 Speaking After showing the students the pictures and their background information, ask the students to think about the question: How do you think seamen found their way before modern accurate methods of navigation were invented?

Listen to the passage and then let them do some true or false questions according to the text.1. I was forced to join Captain Bligh in the small boat. 2. After the crew took over the ship “Boundy”, Captain Bligh was allowed to take with him a chart , a pass and a quadrant.3. It was very difficult for us to get a correct reading from the quadrant as the boat moved constantly during the course. 4. Captain Bligh used a system called “dead reckoning” and he knew there was land directly southwest of their original position. 5. We pletely believed Captain Bligh when he talked hopefully about what we would do when we got back to England.6. Captain Bligh was as weak as the rest of us but he was determined not to give up.7. Captain Bligh kept us busy and tried to take our minds off our stomach and thirst all the way.8. We finally escaped the jaws of death and arrived in Timor over fifty days after being set loose in our small boat.Answers: (FFTFFTTF)b. Give the students a few minutes to read the passage again and then get the general idea of the text. This is the storey of Captain Blighs amazing journey across the Pacific Ocean in an open boat with his followers after another group of sailors under Fletcher Christian had taken over the ship. Later Captain Bligh and his men made for the island of Timor using a bination of navigational skill and “dead reckoning”, which is guessing the correct direction. The voyage lasted over 40 days and was one of the greatest examples of survival at sea. c. Explain some difficult sentences, phrases and words.

You should have reasons for your choice.2. At the time that the nineteen men in the boat sailed for Timor they did not know if they would survive or not. What do you think were the most important things they would need to take with them? Who should decide these items? Remember that the boat was already very full with people and could not hold very much more.3. Many men who wanted to go into the boat were unable to because of the lack of space. If they stayed on the “Bounty” and were caught by the British navy, they should be killed according to the law.4. What would the students have done to avoid being caught and punished if they had been part of the group who took over the “Bounty”? Would they have gone back to Tahiti or looked for another place to live? Which place would be the safest?5. After the discussion let students prepare for the speaking exercise and encourage them to make notes of their ideas. Follow this format: Discuss in pairs. Make a list of the ideas.6. Swap ideas with another pair and resolve differences. Make a new list of the ideas. 7. One member of the group should give the ideas to the class in turn. Other groups can discuss these ideas and evaluate them.One sample dialogue:Li Pei (LP), Du Zhou (DZ), Wen Fuqing (WF) and Liu Yongfu (LY) are discussing the journey and Captains Blighs leadership qualities.LP: Why are you convinced that this journey shows the greatest navigational skill? Im sure there must have been others that were as good, if not better!DZ: Do you know of many other sea voyages of this kind?WF: Well, theres that journey by Shackleton from Elephant Island in the Antarctic to get help from another island with a whaling station. He wanted to rescue his men. The weather was terrible and he was in an open boat, too.LY: How can you think that journey was more difficult? It didnt last very long. Captains Blighs journey lasted over forty days, was very hot and they had very little food and water. It was because Captain Bligh was a great leader that they survived.DZ: Now that Ive heard about it I am very impressed. All those men pushed together in a very small boat, it must have been terrible for them to stay friendly. Meanwhile they were being driven mad by lack of fresh water and there was all that salt water all around them. Thats the reason I think it was the greatest sea escape.LP: When you put it that way I suppose it was a great achievement. Captain Bligh was certainly excellent in the way he kept the men occupied and tried to take their minds off their troubles. In addition he treated everyone the same when it came to food or water. So I think you are right and it was the greatest example of navigational skill against the odds! Do you agree?DA, WF and LY (together): Yes. We do. Step5 HomeworkFinish exercises in workbook.After class write a report to your letter explaining to him why you think Captain Bligh should or should not receive the medal. Sample letterDear Sir，I think Captain Bligh should certainly receive a special medal for his amazing voyage across the sea to Timor. This is a journey that could not have been pleted without great navigational skill. In addition Captain Bligh did not lose one man. First, he showed his leadership qualities by sharing the food and water fairly with the men in the boat. Everyone was treated equally and this made for good feeling between the members of the boat.Second, he kept everyone in the boat cheerful by discussing what they would do when they arrived safely. No one was allowed to think about what might happen if they did not arrive!Third, he kept them occupied by organizing the plicated mathematical calculations needed to find their position at sea. The crew who had taken over the “Bounty” had left Captain Bligh with only a quadrant and a pass. This meant that numerous calculations were needed to find their correct position. Captain Bligh regularly and each person was given a different activity was important because it stopped the men from thinking about how little food and water there was.So I hope you will give Captain Bligh this medal. He has shown leadership, fairness and concern for his crew and helped them return to England safely.

One day he was determined to set out on a across an unknown sea to an unknown continent. He set out with his instruments so he would not be at the of the sea. He found on his journey a rocky island. It seemed to be covered in nests. Suddenly, as Samuel looked, an enormous bird swooped down and picked him up as if he were a/ an parcel. It its speed and rose straight up into the air so as to reach the place on the rocks where its nest lay. Once there, it shook itself and threw Samuel in the direction of the nest. There seemed to be to hide but then he noticed lots of on his left and quickly hid under it. The bird landed nearby and pecked at the rocks. Samuel rolled over swiftly and found himself at the edge of the cliff. He looked down slowly with a beating heart. Below him was his boat lying the shore! “How lucky I am!” Samuel thought to himself. He then gave a mighty leap and landed in it. Once inside he could safely sail away.Suggested answers:Answer key for Exercise 1;1 overhead2 offshore3 alongside 4 simplified; minimum5 voyage; seamenAnswer key for Exercise 2:nowhereanywhere; downloadupload; outwardinward; reliableunreliable;seaweedland flower; shortingstrong pointAnswer key for Exercise 3:NavigationSeanavigate,navigational(instruments:pass, bearing circle, astrolabe, quadrant,sextant), sail,sailor,voyage,latitude,longitude, equator, horizon, captain, sailor, land, island, set sail, nautical middles, explore, exploration , . . .seaman, seaweed, seafood, shore, offshore,onshore,beach, beachbal
