Step Ⅰ Lead-in Living without an aim is like sailing without a compass. Step Ⅱ Warming up Ask the students to turn to page 11 and look at the pictures and talk about them in groups.

What is the difference between a navigator and an explorer? Step Ⅲ Pre-reading 1. Ask students if they have a chance to go on sailing, what instruments they prefer to use. 2. Show students some 4 pictures and then answer the questions Step Ⅳ Reading Page1

Skimming 1.How many skills are mentioned to help the navigators explore the seas? 2.What is the first and most useful form of exploration and has the minimum risk? 3.What does seaweed look like when it is near land? 4.When did seaman use fog to help identify the position of a stream or river? Careful Reading 1. True or False 1).Before the 17th century, the travellers were at the control of the sea without modern 3

navigational aids. 2).Early sailors could use the height of the sun to work out their latitude. 3).Wind could accelerate sailing speed and it was always safe and easy to use.

2.

Please complete the following blanks using the information of the text book. 1) Seamen explored the oceans by using _______ and navigational ___________.

2) Using nature navigators could keep alongside the _______, use such celestial bodies as North Star to _______ their positions, as the sun overhead to _______ by, as clouds over islands to indicate land close 3) Wildlife, especially _______ could tell how far or close the ship was to land and _______ could be used to show the way. Fog could help identify the _______ of a stream or river and winds direct the sailing. Certain tides and currents could be used to carry ships to the Page2 3.Choose the best answer 1).

A. organized

B. intentional

C. arbitrary

4). Without secure method of measuring longitude before the 17th century, the British sailors really knew______.

A. how to estimate longitude using speed and time.

B. how to measure speed involved throwing a knotted rope.

C. how to count the knots as a ship advanced through the water.

D. how to deal with the compass to calculate longitude

5). We can infer from the passage_____. A. Earliest seamen explored the oceans since latitude and longitude made it possible to plot a ship’s position.

4

B. The first seamen began to use navigational instruments to find longitude instead of using nature. C. In history of sailing the oceans, man mainly used nature to sail before navigational instruments were made. 4.

True or False 1).Seamen can’t sail the sea if they don’t know latitude and longitude. 2).The compass always indicate the North Pole, and seamen could find the direction that the ship needed to go with its help. 3). The bearing circle was the first instrument to measure position between the sun and the ship. 4).The astrolabe was a special instrument to tell the distance among the ship, the sun and stars. 5).The quadrant was awkward to handle and used a moving ship as a fixed point of reference. 6). The sextant proved to be the most accurate and reliable one among the early navigational 5.Please complete the following blanks using the information of the text book. 1).Navigational instruments helped the sailor to find ___________. They used the compass to calculate longitude and find the _______ for the ship to go. 2).The _____________ was the first instrument to measure the sun’s position.

3).The astrolabe could tell the position of the _______ in relation to the _______ and stars. 4).The quadrant measured how high stars were above the _______ and the sextant was the updated version of the astrolabe and quadrant, measuring the _______ between two fixed objects outside the ship. It _______ to be the most accurate and reliable of the earlier _____________ instruments. Step V Discussion
