Step1 Greetings Greet the whole class as usual.

Step2 Revision

Check the homework exercises. Step 3 warming up 1.

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. 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 of 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. 2.

Ask the students if they want to know some famous navigators and explorers. Then present them some pictures and some related information about them. (1)About Zheng He. (2)About Marco Polo (3)About James Cook (4)About Ferdinand Magellan

Step 4 Pre-reading

After 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?

Step 5 Fast-reading

1.

How did seamen explore the oceans before latitude and longitude made it possible to plot a ship’s position? Keeping alongside the coastline

Using celestial bodies

Using wildlife

Using the weather

Using the sea

2.

What skills did sailors use to explore the seas and discover new lands? Finding longitude:the compass Finding latitude:the bearing circle (方位圆)\the astrolabe (星盘) \the quadrant (象限仪, 四分仪)\the sextant (六分仪) 3.

Read the passage and answer the following questions. (1)

What is the use of a bearing circle, astrolabe, quadrant or sextant?

(

) What is the use of a compass?

(

)

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 (2) When did early sailors have a practical method of measuring longitude? (3) Which is more precise and simplified, the astrolabe or the quadrant? (4) How did early seamen use weather during the navigation? (5) What does seaweed look like when it is near land? (6) Where are we now when the North Star is along the horizon? 4. Fill in the blanks according to the text (P12- P13). Step 6 Detailed reading A.

Read the passage carefully decide if these sentences are true (T) or false (F). 1. Before modern instruments were invented, people hardly used any navigation.

(

) 2. Early sailors could use the height of the sun to work out their latitude. (

) 3. Seamen can’t sail the sea if they don’t know latitude and longitude. (

) 4. Wind could accelerate sailing speed and it was always safe and easy to use.(

) 5. The compass always indicates the North Pole, and seamen could find the direction that the ship needed to go with its help.(

) B. Read the passage carefully and then answer the questions. 1) Why are speed and time important in working out the longitude of a ship? 2) Why is the position of the sun and various stars useful for working out latitude?

C. Suppose you were a sea captain aiming to sail round Africa. Discuss in groups. 1) What skills would you seek in your sailors? 2) What problems would you anticipate for this journey? D. Read the chart below and fill in your plans of action to deal with them. E. Imagine you are on a boat with twenty-nine other people. You have a small box for your personal things but it can only hold ten items. What would you need for a week’s journey across the North Sea to England? Category Items Category Items Clothes shirt, trousers Shoes waterproof

boots Hygiene soap Tools knife,

scissors

Bedding blanket Medicines sea-sick

tablets, cold

medicine

Games cards, chess Books novels, essay collections

A. why early seamen wanted to sail the seven seas B. that there is useful information in an encyclopedia C. that early sailors went exploring the seas using their skills and simple instruments D. why latitude and longitude are important to plot a ship’s position

2. the reading passage mainly wants to tell us________. A. that keeping alongside the coastline is first and most useful form of exploration B. about the skills and navigational aids early seamen used while sailing the oceans C. that finding longitude and latitude is a must to plot a ship’s position on a map D. how the early sailors used their skills and simple instruments Step 8 Homework 1.
