Step 3 Presentation
Present 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 Discussion
In 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.
