Part One: Teaching Design

Period 1: A sample lesson plan for reading (SAILING THE OCEANS) Aims

To help students read about sailing the oceans

To help students learn about the predicate Procedures

■Warming up by leaning about navigator What is a navigator?

A navigator is the person onboard a ship responsible for the navigation of the vessel. On aircraft, the position may also be referred to as a flight officer. The navigator's responsibilities include planning the journey, advising the captain (or pilot) while en route, and ensuring that hazards or obstacles are avoided.

What is exploration?

Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown regions, including space (space exploration), or oil, gas, coal, ores, water (also known as prospecting), or information.

Exploration has existed as long as human beings, but its peak is seen as being during the Age of Exploration when European navigators travelled around the world.

In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Exploration is the attempt to develop an initial, rough understanding of some phenomenon.

■Warming up by talking about Zheng He's Seven Voyages In July 11, 1405, the eunuch Zheng He of the Ming Dynasty royal court set out on his first overseas voyage. In the following 28 years, this navigator proceeded to carry

out six more voyages, accompanied by a huge entourage of nearly 30,000 people. By traveling throughout Southeast Asia, and around the Indian Ocean to the Red Sea and East Africa, he also landed at over thirty different nations.

He was the earliest largest scale navigation in world history, coming more than half a century earlier than Columbus'famous exploits...

■Warming up by looking and listening

Hello, class. Do you know this man? Yes, he is Marco Polo.

Marco Polo (1254-1324), is probably the most famous Westerner traveled on the Silk Road. He excelled all the other travelers in his determination, his writing, and his influence. His journey through Asia lasted 24 years. He reached further than any of his predecessors, beyond Mongolia to China. He became a confidant of Kublai Khan (1214-1294). He traveled the whole of China and returned to tell the tale, which became the greatest travelogue.

I. Pre-reading

What are navigational instruments?

●Navigational instruments were built in the age of exploration to guide the explorers to their destinations.

●navigational instrument - an instrument used for navigating

artificial horizon, flight indicator, gyro horizon - a navigational instrument based on a gyroscope; provides an artificial horizon for the pilot compass - navigational instrument for finding directions

depth finder - navigational instrument used to measure the depth of a body of water (as by ultrasound or radar)

inclinometer - an instrument showing the angle that an aircraft makes with the horizon instrument - a device that requires skill for proper use

asdic, echo sounder, sonar - a measuring instrument that sends out an acoustic pulse in water and measures distances in terms of the time for the echo of the pulse to return; sonar is an acronym for sound navigation ranging; asdic is an acronym for anti-submarine detection investigation committee

II. Reading for forms

Read the text SAILING THE OCEANS on page 12 to: cut/ the sentence into

thought groups, blacken the predicative, darken the connectives and underline all the useful expressions.

SAILING THE OCEANS

We may well wonder/ how seamen explored the oceans/ before latitude /and longitude made it possible /to plot a ship's position/ on a map．The voyages of travelers/ before the 17th century /show that /they were not at the mercy of the sea /even though they did not have modern navigational aids．So/ how did they navigate so well? Read these pages/ from an encyclopedia．

Page l：

Using nature to help

Keeping alongside the coastline

This seems to have been the first /and most useful form of exploration /which carried the minimum amount of risk．

Using celestial bodies

North Star

At the North Pole /the North Star is at its highest position /in the sky, but at the equator /it is along the horizon．So /accomplished navigators were able to use it /to plot their positions．

Sun

On a clear day /especially during the summer/ the sailors could use the sun /overhead /at midday to navigate by．They can use the height of the sun /to work out their latitude．

Clouds

Sea captains observed the clouds /over islands. There is a special cloud formation /which indicates /there is land/ close by. Using wildlife

Seaweed

Sailors often saw seaweed/ in the sea /and could tell /by the colour /and smell/ how long it had been there．If it was flesh /and smelled strongly，then /the ship was close to land．

Birds

Sea birds could be used to show the way/ to land /when it was nowhere to be seen．In the evening /nesting birds return to land /and their nests．So /seamen could follow the birds /to land /even if
