Step I

Warming up What is the difference between a navigator and an explorer? Navigator is somebody who finds the position and plots the course of a ship using

maps and instruments. Explorer is somebody who travels into or through a place in order to learn about it.Very often navigators are also explorers. Step II reading First let the Ss discuss the three questions, and then collect answers from the students. A few minutes later, Decide whether the following statements are true (T) or false (F). 1.

An early method of calculating longitude was to use a knotted rope tied to a log.

(T)

2. The astrolabe was the first instrument to measure the sun’s position.(F)

3. The quadrant was more precise and simplified than the astrolabe, but still had its shortcoming. (T)

4.Up till now, the most accurate

and reliable navigational instrument is the sextant.

(F)

5.

The astrolabe, quadrant and sextant are different kinds of navigational instruments and they have nothing to do with each other.(F) Second Comprehending 1.What’s the main idea of the passage? The reading passage explains how seamen explored the oceans and what kind of navigational instruments were used to sailors before the seventeeth century. 2.

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 3.Why are speed and time important in working 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.

Step III Discussion Suppose you were a sea captain aiming to sail round Africa.

Discuss in groups: What skills would you seek in your sailors?

Step IV Summary Read the passage again and use the information to analyze the navigational skills.

Step VI Homework 1. Review this passage. 2. Preview Learning about language.
