Upon yet again discovering that something did not exist，he continued his voyage.His last stop was in February，1779 at Hawaii where he was killed in a fight with islanders over the theft of a boat.
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.
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.

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 tal king about Zheng He's Seven V oyagesIn July 11, 1405, the eunuch Zheng He of the Ming Dynastyroyal court set out on his first overseas voyage.In the following 28 years, this navigator proceeded to carryout 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 half a 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. Pre-readingWhat are navigational instruments?●Navigational instruments were built in the age of exploration to guide the explorers to their destinations.●na vigational instrument - an instrument used for navigatingartificial horizon, flight indicator, gyro horizon - a navigational instrument based on a gyroscope; provides an artificial horizon for the pilotcompass - navigational instrument for finding directionsdepth finder - navigational instrument used to measure the depth of a body of water (as by ultrasound or radar)inclinometer - an instrument showing the angle that an aircraft makes with the horizon instrument - a device that requires skill for proper useasdic, echo sounder, sonar - a measuring instrument that sends out an acoustic pulse in water and measures distances in terms of the time for the echo of the pulse to return; sonar is an acronym for sound navigation ranging;asdic is an acronym for anti-submarine detection investigation committeeII.

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 islandsof Micronesia. Before modern navigational techniques were developed,navigators in the South Pacific relied on stick charts to indicate island locationsrelative to winds andcurrents.Today, racing sailboats is a sport, and teams test their skills by racing around theworld. 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.Additional MaterialsComplete the summary of the story with one word in each blank.While sailing the _____1___we may make use of both the nature ___2___ the。

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.
