Unit 2 Sailing the oceansPart One: Teaching DesignPeriod 3: A sample lesson plan for Using Language (THE GREATEST NA VIGATIONAL JOURNEY: A LESSON INSURVIV AL)AimsTo help students read the passage THE GREATEST NA VIGATIONAL JOURNEY: A LESSON IN SURVIV AL To help students to use the language by reading, listening, speaking and writingProceduresI. Warming up by learning something about William BlighWilliam Bligh in 1814Vice Admiral of the Blue William Bligh, FRS (9 September 1754 - 7 December 1817) was an officer of the British Royal Navy and colonial administrator. He is best known for the famous mutiny that occurred against his command aboard HMA V (His Majesty's Armed Vessel) Bounty and the remarkable voyage he made to Timor on the Bounty's launch after being set adrift by the mutineers. Many years after the Bounty mutiny he was appointed Governor of New South Wales, with a brief to clean up the corrupt rum trade of the NSW Corps. He had some success in his task but quickly faced opposition which culminated in the Rum Rebellion led by John Macarthur. Although William Bligh was certainly not the vicious man portrayed in popular fiction, some claim his over-sensitivity and acid tongue damaged what would have otherwise been a distinguished career.II.

Copying expressions and making sentencesIV. Listening and speaking about Viking sailing and Polynesian seamenThe name Viking is a borrowed word from the native Scandinavian term for the Norse warriors who raided the coasts of Scandinavia, the British Isles, and other parts of Europe from the late 8th century to the 11th century. Vikings traveled to the west and Varangians, who were best known as the Varangian Guards of the Byzantine emperors, to the east. This period of European history (generally dated to 793 - 1066 AD) is referred to as the Viking Age.The word “Viking” was introduced to the English language with romantic connotations in the 18th century. Today, somewhat controversially, the word is also used as a generic adjective, referring to the Viking Age Scandinavians. The medieval Scandinavian population, in general, is more properly referred to as Norse.Where is Polynesia?A division of Oceania including scattered islands of the central and southern Pacific Ocean roughly between New Zealand, Hawaii, and Easter Island. The larger islands are volcanic, the smaller ones generally coral formations.Now go to page 19. L et’s go to listen to something about Viking sailing the oceans. While listening try to circle those aids in the box on page 19 that the early sailors used to find their ways at sea. Now you shall listen to the tape once again to fill in the chart on page 19.On page 20 there are four sayings from Polynesian seamen.What does each of them mean?Now in pairs talk about each of the sayings.V. Closing down by Zheng He, a great Chinese sailorCheng Ho or Zheng He (both: jŭng' hʊ') , 1371–c.1433, admiral, diplomat, and explorer during China's Ming dynasty. At 10 he was captured by Chinese troops in Yunnan, castrated, and sent into the army. He rose in the ranks, became an officer, and in 1404 was named Grand Eunuch by Emperor Yung-lo. The following year the emperor selected him to lead the first of seven epic expeditions (1405–33) that served to expand Chinese political influence and increase its tribute and trade. Sailing to SE Asia (1405–07), he commanded 62 ships laden with porcelain, lacquer, silk, gems, and other luxury goods. Subsequently commanding treasure fleets ranging from about 50 to more than 100 vessels, some of which were 500 ft (153 m) long, he also later sailed to India, Sri Lanka, Arabia, E Africa, and Egypt. On his fourth voyage (1413–15), Cheng returned with envoys from 30 foreign states who rendered homage to the emperor and sailed home on his sixth voyage (1421–23). Although China returned to an isolationist policy after the emperor's death (1424), Cheng made one last voyage (1431–33). A controversial theory posits that Cheng discovered the New World during his 1420s voyage, some 70 years before Columbus.。

高中英语 Unit 2 Sailing the oceansA History of Sailing
A History of Sailing Boat and A History of Steamboat Authoredby Academician Yan You PublishedA History of Sailing Boat and A History of Steamboat, two books authored by Professor Yan You, an academician of Chinese Academy of Sciences and a famous expert on the design and construction of naval architecture and ocean structure and a historian of science and technology, were published by Shanghai Jiao Tong University Press. These two books are part of the series of books intended to publicize science and have a pretty high value in science.Professor Yan You has been devoted to the manufacturing, education and research of naval architecture and held a long-term position of the deputy director of China Society of Naval Architecture and Ocean Engineering and China Society of Ocean Engineering. Since the year 1962, he has been dedicated to the research on the history of naval architecture in China and the world with a series of papers like the Brief History of the Development of the Naval Architecture in China. In these newly published books, Professor Yan provided a vivid picture of the characteristics and the development history of the sailing boats and steamboats in China and the world with concise words and a large number of pictures.By comparison with the books of this kind in China, this series of books place an emphasis on the development history of the naval architecture and ocean engineering in the eastern countries. The Silk Road on the Sea, the Western Voyage of Zheng He (a great Chinese ocean explorer in the Ming Dynasty) and the South Island dialect speakers’ naval achievements are all introduced in the books with the false information removed from the skeptical events in the history, which reflects an old scientist’s spirit of seeking truth in scientific research.1。

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 we’ll 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 MagellanStep 6 SpeakingAfter 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? If time is limited, this can be left as their homework.Step 7 Homework1. Read the new words.2. Preview Reading SAILING THE OCEANS on page 12.The Second Period ReadingTeaching Aims:a.

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 compass 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 completely 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 Bligh’s 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 combination 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.Key phrases:1. in addition 另外There was an earthquake and, in addition, there were tsunamis.除了地震之外，还有海啸。

Unit 2 Sailing the oceansPart One: Teaching DesignPeriod 1: A sample lesson plan for reading(SAILING THE OCEANS)AimsTo help students read about sailing the oceansTo help students learn about the predicateProcedures■Warming up by leaning about navigatorWhat is a navigator?A navigator is the person onboard a ship responsible for the navigation of the vessel. On aircraft, the position may also be referred to as a flight officer. The navigator's responsibilities include planning the journey, advising the captain (or pilot) while en route, and ensuring that hazards or obstacles are avoided.What is exploration?Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown regions, including space (space exploration), or oil, gas, coal, ores, water (also known as prospecting), or information.Exploration has existed as long as human beings, but its peak is seen as being during the Age of Exploration when European navigators travelled around the world.In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Exploration is the attempt to develop an initial, rough understanding of some phenomenon.■Warming up by talking about Zheng He's Seven VoyagesIn July 11, 1405, the eunuch Zheng He of the Ming Dynasty royal court set out on his first overseas voyage.In the following 28 years, this navigator proceeded to carry out six more voyages, accompanied by a huge entourage of nearly 30,000 people. By traveling throughout Southeast Asia, and around the Indian Ocean tothe Red Sea and East Africa, he also landed at over thirty different nations.He was the earliest largest scale navigation in world history, coming more than halfa century earlier than Columbus'famous exploits...■Warming up by looking and listeningHello, class. Do you know this man? Yes, he is Marco Polo. Marco Polo (1254-1324), is probably the most famous Westerner traveled on the Silk Road. He excelled all the other travelers in his determination, his writing, and his influence. His journey through Asia lasted 24 years. He reached further than any of his predecessors, beyond Mongolia to China. He became a confidant of Kublai Khan (1214-1294). He traveled the whole of China and returned to tell the tale, which became the greatest travelogue.I.

Closing down by reading more about sailing the oceansSailing the oceansFor thousands of years, people have been sailing across the oceans and around the world. Knowledge of ocean currents and wind patterns has allowed people to reliably reach their destinations even after crossing huge expanses of open ocean.In this photograph, a sailboat uses wind and currents to move among the islands of Micronesia. Before modern navigational techniques were developed, navigators in the South Pacific relied on stick charts to indicate island locations relative to winds andcurrents.Today, racing sailboats is a sport, and teams test their skills by racing around the world. Navigation now relies on satellites, but knowledge of wind patterns, ocean currents, and potential obstacles in unfamiliar waters is still essential for sailing.In this investigation, you'll plot a course for racing around the world in a sailboat. You'll explore some of the obstacles you might encounter on your route; then you'll have the opportunity to revise your route to improve your speed.。
