Pre-reading • Look at the pictures. Then answer the questions. 1 How do you think seamen found their way before modern accurate methods of navigation were invented? Kept close to the shore, used nature such as the sun, wind, birds, tide, etc, to help them, and used some of the instruments including a compass, astrolabe, etc.
In pairs discuss these questions: 1 What is a navigator? A navigator explores new routes across the sea. 2 What is the difference between a navigator and an explorer? A navigator explores the sea; an explorer discovers new places on land.
3 Why is the position of the sun and various stars useful for working out latitude? The position of the sun and stars are useful for working out latitude because they are fixed points in the sky and their movements in relation to the earth are already known. So they can be used to measure a ship's positiead the passage and answer the following questions. 1 What is the use of a bearing circle, astrolabe, quadrant or sextant? ( B) What is the use of a compass? (A ) A to set the course of the ship B to measure the position of the ship C to measure the speed of the ship D to tell the time
Explorer land use of compass and landmarks find new places within an already identified island or continent Explorer is someone who travels into or through a place in order to learn about it. Very often navigators are also explorers.
3 Can you identify these early navigational instruments seamen used and explain how they are used? compass (in ancient China) 1 _________________________ 2 _________ astrolabe 3 _________ sextant sea / nautical / marine chart 4 ________________________ 4 Which ones do you think are still used today? Sea charts are still used today.
2 Why are speed and time important in working out the longitude of a ship? Speed and time are important in finding out the longitude of a ship because the earth moves fifteen degrees westwards every hour. If you know your direction, speed and time, you can work out the approximate longitude or change in your position in relation to the stars.
3 Look at these famous people. Are they navigators or explorers? What do you know about them? Navigator sea nautical instruments find new islands or continents Navigator is someone who finds the position and plots the course of a ship, an aircraft, a car, etc, using maps and instruments.
2 Which do you think was easier to work out: latitude or longitude? Latitude, because it was used to measure how far you had travelled from land on a straight line. It was discovered a long time before longitude.

Sailing the oceans
• James Cook was born in 1728 in Marton，England.His father， a Scottish migrant farm worker，allowed James to work on coal －carrying boats at eighteen.Cook spent his free time learning math and navigation.This led to his appointment as mate (大 副)．
• The Third Voyage.
• The Navy wanted Cook to determine if there was a Northwest Passage，a mythical waterway between Europe and Asia across the top of North America.Cook set out in July of 1776 and rounded the southern tip of Africa and headed east across the Indian Ocean until his navigation of the Bering Sea was stopped by the impassible Arctic ice.
• Cook’s explorations greatly increased European knowledge of the world.As a ship captain and skilled cartographer，he filled in many gaps on world maps.His contributions to eighteenth century science helped further exploration and discovery for many generations.
