Teaching procedure 教学过程

Step1 Leading in

1.

Greet each other and then ask students to read the words of this unit. 2.

Tell them we’re to learn the Reading of Unit2 today.

Step2

Warming Up 1.

Show Ss three people on the screen: Zheng He,Marco Polo, James Cook. Then discuss the following questions in pairs：

(1)．What is a navigator? (2)．What is the difference between a navigator and an explorer? (3)．Look at these famous people.Are they navigators or explorers? 2..After a short discussion , share the keys with the Ss and tell them to think deeply. Keys to the Qs: (1).A navigator explores new routes across the sea. (2)．A navigator explores the sea；an explorer discovers new places on land. (3)．Zheng He is a navigator；Marco Polo is an explorer；James Cook is an explorer. Step3:Pre－reading

Ask the students to look at the pictures.Then answer the questions.

Q1．How do you think seamen found their way before modern accurate methods of navigation were invented? Q2．Can you identify these early navigational instruments seamen used and explain how they are used? (1)___________________________________________ (2)___________________________________________ (3)___________________________________________ (4)___________________________________________ .

Step4 Fast Reading

Ask the students to fast-read the text and choose the right answer according to the text. 1．When did early sailors have a practical method of measuring longitude? A．The 12th century.

B．The 17th century. C．The 15th century. D．The 16th century. 2．What does seaweed look like when it is near land? A．It looks nice. B．It looks small. C．It looks fresh.

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 5．The main idea of this passage is about____________. A．that keeping alongside the coastline is first and most useful form of exploration B．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

When the Ss have finished the exercise, check the answers with them and explain. Step5. Careful reading 1.

Ask Ss to read the whole text more carefully.

2.

Correct the mistakes below according to the text.

1．We may well wonder how seamen explored the oceans before latitude and longitude made possible to plot a ship’s position on a map. 答案：

made后加it 2．There is a special cloud formation which indicates there is land close. 答案：

close后加by 3．Sailors often saw seamen in the sea and could tell through the colour and smell how long it had been there. 答案：

through→by 4．Sea birds could be used to showing the way to land when it was nowhere to be seen. 答案：

showing→show 5．An early method of measuring speed involved throwing a knotted rope tying to a log over the side of the ship. 答案：

tying→tied Step6. Post reading and Summary Today we’ve learned a text about sailing the ocean so now let’s finish the following summary of the text to

consolidate what has been learned in this class.

This reading explains how seamen 1._____(explore) the oceans and what kind of navigational instruments were used to sailors 2._____the seventeenth century 3._____they were navigating the open seas without seeing land.The 4.______(voyage) of travelers before the 17th century show that they were not 5._____the mercy of the sea even though they did not have modern 6.______(navigation) aids.The seamen could use celestial bodies，wildlife，the weather or the sea to keep 7.______the coastline.They could also use 8.____________compass to help find the direction that the ship needs to go.They could use the 9.____________(bear) circle to measure the sun’s position and tell if they were sailing on their correct rather than a random course.While the astrolabe，the quadrant and the sextant could help give the seamen the local time and allowed them to find their 10.____________at sea. 答案：

1.explored
