Unit Eight Travel

I.Teaching Objectives:

Students will be able to :

1.understand the main idea and structure of the text;

2.appreciate the fluid and sensual writing style;

3.grasp the key language points and grammatical structures

in the text;

4.conduct a series of reading, listening, speaking and

writing activities.

II.Text Analysis:

The text is beautifully written. That’s why we arrange a post-reading activity simply for students to share favorite sentences with each other. It may be true that the functional use of English will dominate in their life, but it pays to expose them to the aesthetic side of English.

There is an abundance of sensory impressions in the essay.

All of our five senses are appealed to here. We hear the songs of birds, insects and children. We feel the coolness of drinks and the night. We smell the sweetness in the air.

We observe the wonderful sights and graceful movements on the river, on the lake and in the jungle. We taste the

delicious village food.

Not only does the author move effortlessly from one sensory impression to another, but she also handles the changes in time and place in a smooth, seamless way. In part II, she first writes about what happened “later that night”, then moved back to narrate the incidents of “ that afternoon”, finally back to “now”. she was sitting on a tree stump on the river bank near a palm-thatch village in Part I, then she sat in a camp in Part II, went on a journey away from the river into the jungle and finally returned to riverside village in Part III.

All through these movements there is overall coherence.

There is an echo—“It would be worth it”, “The Napo River: it is not out of the way. It is in the way.”

III.Cultural Notes:

1.Amazon (river): river in northern South America, largely

in Brazil, ranked as the largest in the world in terms of

watershed area, number of tributaries, and volume of

water discharged. Measuring 6,400 km (4,000 mi) from

source to mouth, it is second in length only to the Nile

among the rivers of the world. With its hundreds of

tributaries, the Amazon drains a territory of more than 6

million sq km (2.3 million sq mi), roughly half of which is in Brazil; the rest is in Peru, Ecuador, Bolivia, and Venezuela. It is estimated that the Amazon discharges between 34 million and 121 million liters (9 million and

32 million galleons) of water per second and deposits a

daily average of 3 million tons of sediment near its mouth.

The annual outflow from the river accounts for one-fifth of all the fresh water that drains into the oceans of the world. The outpouring of water and sediment is so vast that the salt content and color of the Atlantic Ocean are altered for a distance of about 320 km (about 200 mi) from the mouth of the river.

2.Ecuador:republic in northwestern South America,

bounded by Colombia on the north, by Peru on the east and south, and by the Pacific Ocean on the west. The country also includes the Galapagos Islands in the Pacific, about 965 km (about 600 mi) west of the mainland.

Ecuador straddles the equator and has an area of 272,045 sq km (105,037 sq mi). Quito is the country’s capital.

Ecuador has a diverse population composed of people of European, Native American, and African descent. The majority are Mestizos, individuals of mixed European and

Native American ancestry. Most of the Native Americans live in poverty in the highlands region, where a small elite of European descent controls most of the land and wealth.

Ecuador was a Spanish colony until 1822, when independence forces won a decisive victory over Spain.

Ecuador has had a democratically elected government since 1979, but historically the government has alternated between civilian rule and military dictatorship. Most political conflicts involved squabbles among groups within the upper classes who controlled the nation’s wealth.

3. Andes:the principal mountains of South America and

one of the greatest mountain systems of the world. The Andes include some of the world’s highest peaks. More than 50 of them soar higher than 6,100 m above sea level. Only the Himalayas of south central Asia are higher. The lofty plateaus and high mountain valleys of the Andes contain some of the highest permanent human settlements in the world. The Andes are the longest system of high mountain ranges on earth. They extend for more than 8000 km in a narrow belt along the western edge of the South American continent, from the

coast of the Caribbean Sea in the north to the island of

Tierra del Fuego in the extreme south. Along almost its

entire length, the Andes rise abruptly from the Pacific

coast. The mountains reach into seven countries.

Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and

Argentina.
