■Warming up by leaning about navigator
What 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.
■Warmin g up by talking about Zheng He's Seven V oyages
In 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 to
the 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 listening
Hello, 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.

before latitude /and longitude made it possible /to plot a ship's
position/ on a map．The voyages of travelers/ before the 17th
century /show that /they were not at the mercy of the sea
/even though they did not have modern navigational aids．So/ how did they navigate so well? Read these pages/ from an encyclopedia．
