Great European Cities

PARIS

Paris is the capital and largest city of France, situated on River Seine. It is one of the most beautiful cities in the world and is visited by more than eight million tourists every year. The most popular place for tourists is the Eiffel Tower, the famous symbol of Paris. One of the world’s largest art galleries, the Louvre, is also located in Paris. The city is also located in Paris. The city is also famous for its restaurants, cafes and theatres. About two-thirds of France’s artists and writers live in Paris.

BARCELONA

Barcelona is the second largest city of Spain and is situated on the northeast coast, about five hundred kilometres east of the Spanish capital, Madrid. One of Barcelona’s most famous landmarks is the Church of Sagrada Familia, which was designed by an architect called Antonio Gaudi. Gaudi worked on the project from 1882 until his death in 1926. The church hasn’t been finished yet!

FLORENCE

Florence is an Italian city which became famous because of the Renaissance, a great artistic movement which began in the 1300s and lasted for three hundred ears. During the Renaissance, some of the greatest painters of all time lived and worked in Florence. Many of Florence’s most beautiful paintings and sculptures were produced by great artists such as Leonardo da Vinci and Michelangelo. Florence is visited each year by about a million tourists who come to see the art galleries, churches and museums. The Uffizi Palace is the most famous art gallery in the city.

ATHENS

Athens, the capital of Greece, is known as the birthplace of western civilization. Two thousand four hundred years ago, it was the world’s most powerful city. Buildings such as the Parthenon on the Acropolis Hill were built during this period. Greece’s best writers lived in ancient Athens. Their work has influenced other writers ever since.

The Human Development Report

In the year 2000, 147 world leaders agreed to work together to reduce poverty by 2015 or earlier. From this agreement came the Human Development Report.

One of the most important sections of this report is the Human Development Index. This examines the achievements of 175 countries. The Index measures a country’s achievements in three ways: life expectancy (how long people usually live), education and income. The index has some surprises. Norway is at the top of the list, while the US is at number 7. The other top five countries are: Iceland(2), Sweden(3), Australia(4), the Netherlands(5). The UK is in the thirteenth position, while China is in the middle of the list. The bottom ten countries are all African countries, with Sierra Leone(in West Africa) at the bottom of the list.

The report describes eight Development Goals. The most important goals are to:

Reduce poverty and hunger;

Make sure that all children have education up to the age of 11;

Fight AIDS and other diseases;

Improve the environment of poor people, e.g. make sure they have safe drinking water;

Encourage developed countries to give more help to other countries.

The 2003 Human Development Report gives examples of successful development. For example, in nine years, China increased life expectancy by 13 years. In the last ten years in China, 150 million people moved out of poverty. However, the challenges are still great. Every day 799 million people in developing countries are hungry. Over half of these are in South Asia or Africa. Although more than 80% of children in developing countries go to primary school, about 115 million children are not being educated. More than 1 billion people in developing countries do not drink safe water. However, in other regions of the world, e.g. Eastern Europe, water is now mostly safe to drink.

The report shows that we are making some progress but that we need to make greater efforts. Although developed countries give some financial help, they need to give much more. Interestingly, the countries that give the most money are the Netherlands, Norway and Sweden. These are among the five richest countries in the world , so it is right that they should do so.

The Violence of Nature

What is a Tornado?

A tornado is a rotating column of air from a thunderstorm to the ground. The most violent have winds of more than 400 kilometres per hour. Almost all of them occur in the US, in the area from Texas in the southeast to South Dakota in the north.

Tornadoes can pick up cars, trains and even houses and put them down in the next street—or even in the next town. They can tale the fur off the back of a cat and the feathers off a chicken. They can destroy houses, but leave the furniture inside exactly where it was.

On average, there are 800 tornadoes in the us each year, causing about 80 deaths and 1500 injuries. The worst tornado of all time occurred in 1925, affecting three US states: Missouri, Illinois and Indiana. By the time it ended, more than 700 people had been killed and 2700 had been injured.

What Is a Hurricane?

Hurricanes are strong tropical storms, and they usually occur in the southern Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. There are violent winds of 120 kilometres per hour or more, which cause huge waves, heavy rain and floods. There are on average six Atlantic hurricanes each year and they usually affect the east coast of the US from Texas to Maine.

The worst hurricane disaster of all time occurred on the 8th September 1900 in Galveston, Texas. Winds of 200 kilometres per hour and five-metre-high waves hit the city. The disaster killed 6000 people in a population of 37000 and destroyed 3600 buildings.

An Extraordinary Event

This is a story about the 1900 Galveston hurricane. Charles Coghlan was a nineteenth-century Irish actor who went to live in Canada. He then moved to New York, where he became famous. By the late 1890s, he had moved to Galveston, where he died in 1899, a year before the hurricane struck. The cemetery where Goghlan was buried was destroyed by the hurricane and Goghlan’s coffin ended up in the sea.

Eight years later, the coffin was found by fishermen in the sea near his home on Prince Edward Island in the east of Canada. The Gulf Stream had carried it 3000 kilometres up the eastern US coast to Prince Edward Island. Coghlan traveled back to Canada—after he had been buried in Texas!

Sandstorms in Asia

Sandstorms have been a major disaster for many Asian countries for centuries. Scientists have tried many ways to solve this problem and in China, a mass campaign has been started to help solve it.

Sandstorms are strong, dry winds that carry sand. They are often so thick that you cannot see the sun, and the wind is sometimes strong enough to move sand dunes. The four main places in the world where there are sandstorms are Central Asia, North America, Central Africa and Australia. Ren Jianbo, from Inner Mongolia described a terrible sandstorm he experienced as a child in the desert. “To have been caught in a sandstorm was a terrible experience,” he said. “There was nothing to be done. It was the most frightening and the most dangerous situation I’ve ever been in. You just had to hope you’d survive. I thought I was going to disappear under the sand.” Northwest China is part of the sandstorm centre in Central Asia. Sandstorms begin in desert areas. Sandstorms in China appear to have increased in recent years as a result of “destertification”. This is a process that happens when land becomes desert because of climate changes and because people cut down trees and dig up grass.

Sandstorms sometimes affect Beijing. Citizens wake up to an orange sky and strong winds that cover the city in a thick, brown-yellow dust. The storms sometimes continue all day and traffic moves very slowly because the thick dust makes it difficult to see.

The Chinese Central Weather Station can forecast a sandstorm some weeks before it arrives in Beijing, but the strength of the storm sometimes surprises people. When a sandstorm arrives in the city, weather experts advise people not to go out. Huang Xiaomei, who lives in Beijing says, “To be cycling in a sandstorm is frightening. The winds are very strong. It’s difficult to breathe and the dust makes me ill. So if you want to go out, you’d better wear a mask.”

The desert is only 250 kilometres away to the west of Beijing. To prevent it coming nearer, the government is planting trees. Already the government has planted more than 30 billion trees and plans to continue planting for the next five years.

Philosophers of Ancient China

Ancient China was a place where states were often at war with each other. But it was also a time when there were many great philosophers. Confucius is the philosopher whose influence has been the greatest. He stressed the importance of kindness, duty and order in society. Chinese society was influenced by these ideas for more than 2000 years.

Mencius was a thinker whose teachings were very similar to those of Confucius. Mencius was born in 372 BC. His father died when he was young, and he was brought up by his mother. He became a student of Confucius’s ideas, and was then given an important position in the government of a state. However, when he saw that the ruler was not following his advice, he resigned. For many years he traveled from state to state, teaching the principles of Confucius. He then became an adviser to another ruler. He spent his last years preparing a book of his teachings called the Book of Mencius. Mencius believed that the reason why man is different from animals is that man is good. He taught that if the government was kind, then people would be good. He believed that people were more important than rulers, and hated the state when it treated people badly.

Mozi was another teacher who was very influential. Born in 476 BC, he came from a family which was very poor. He became famous for his unusual clothes and behaviour. Mozi founded the philosophy called Mohism. In some ways, his beliefs were similar to those of Confucius. For example, he considered that government was most important. As a result, he spent many years trying to find a state where people would follow his teachings. Mozi believed that all men were equal. His ides of love was different from the Confucian idea of kindness. Mozi taught that we should love all human beings and look after those who are weaker than ourselves. He hated the idea of war. Mozi died in 390 BC.

The Three Gorges Dam

“Walls of stone to hold back clouds and rain”

Mao Zedong wrote a poem in which he dream of “walls of stone to hold back clouds and rain till a smooth lake rises in the narrow gorges”. Now his dream has come true. The power of the Yangtze River, which is the world’s third longest river, has been harnessed by the Three Gorges Dam.

The Three Gorges Dam, which is the biggest construction project in China since the building of the Great Wall and the Grand Canal, has been built to control flooding and provide hydro-electric power for the central region of China. The dam is nearly 200 metres high and 1.5 kilometres wide. It is the largest hydro-electric power station and dam in the world and has cost more than any other construction project in history.

Sun Yan-sen, who was the leader of the 1911 Revolution, first suggested the idea of a dam across the Yangtze River in 1919. Three quarters of China’s energy is produced by burning coal. In 1993, China used 1.2 billion tons of coal for heating and generating electricity. Unfortunately, burning coal causes serious air pollution and increases global warming(来自:WwW.hn1C.Com 唯 才 教育 网:高中英语必修三课文原文). The dam will generate electricity equal to about 40 million tons of coal without causing so much air pollution.

The reservoir has flooded 2 cities, 11 counties, 140 towns and more than 4000 villages. More than a million people who lived in the region have moved from their homes. Now they’re living a happy new life in different areas.

The Three Gorges area is one of the most beautiful areas of China and the project has flooded some of China’s

most famous historical sites, including the Qu Yuan Temple, the Han Watchtower and the Moya Cliff carvings. About 800 historical relics have been submerged. Some of them are being removed and some are being put into museums.

Unit 1 Festivals around the world

FESTIVALS AND CELEBRATIONS

Festivals and celebrations of all kinds have been held everywhere since ancient times. Most ancient festivals would celebrate the end of cold weather, planting in spring and harvest in autumn. Sometimes celebrations would be held after hunters had caught animals. At that time people would starve if food was difficult to find, especially during the cold winter months. Today’s festivals have many origins, some religious, some seasonal, and some for special people or events. Festivals of the dead

Some festivals are held to honour the dead or to satisfy the ancestors, who might return either to help or to do harm. For the Japanese festival Obon, people should go to clean graves and light incense in memory of their ancestors. They also light lamps and play music because they think that will lead the ancestors back to earth. In Mexico, people celebrate the Day of the Dead in early November. On this important feast day, people eat food in the shape of skulls and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The Western holiday Halloween also had its origin in old beliefs about the return of the spirits of dead people. It is now a children’s festival, when they can dress up and go to their neighbours’ homes to ask for sweets. If the neighbours do not give any sweets, the children might play a trick on them.

Festivals to Honour People

Festivals can also be held to honour famous people. The Dragon Boat Festival in China honours the famous ancient poet, Qu Yuan. In the USA, Columbus Day is in memory of the arrival of Christopher Columbus in the New World. India has a national festival on October 2 to honour Mohandas Gandhi, the leader who helped gain India’s independence from Britain.

Harvest Festivals

Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter and the agricultural work is over. In European countries, people will usually decorate churches and town halls with flowers and fruit, and will get together to have meals. Some people might win awards for their farm produce, like the biggest watermelon or the most handsome rooster. China and Japan have mid-autumn festivals when people admire the moon and in China enjoy moon-cakes.

Spring Festivals

The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. At the Spring Festival in China, people eat dumplings, fish and meat and may give children lucky money in red paper. There are dragon dances and carnivals, and families celebrate the Lunar New Year together. Some Western countries have very exciting carnivals, which take place forty days before Easter, usually in February. These carnivals might include parades, dancing in the streets day and night, loud music and colourful clothing of al kinds. Easter is an important religious and social festival for Christians around the world. It celebrates the return of Jesus from the dead and the coming of spring and new life. Japan’s Cherry Blossom Festival happens a little later. The country, covered with cherry tree flowers, looks as though it is covered with pink snow.

People love to get together to eat, drink and have fun with each other. Festivals let us enjoy life, be proud of our customs and forget our work for a little while.

A SAD LOVE STORY

LI Fang was heart-broken. It was Valentine’s Day and Hu Jin had said she would meet him at the coffee shop after work. But she didn’t turn up. She could be with her friends right now laughing at him. She said she would be there at seven o’clock, and he thought she would keep her word. He had looked forward to meeting her all day, and now he was alone with his roses and chocolates, like a fool. Well, he was not going to hold his breath for her to apologize. He would drown his sadness in coffee.

It was obvious that the manager of the coffee shop was waiting for Li Fang to leave - he wiped the tables, then sat down and turned on the TV - just what Li Fang needed! A sad Chinese story about lost love.

The granddaughter of the Goddess of Heaven visited the earth. Her name was Zhinü, the weaving girl. While she was on earth she met the herd boy Niulang and they fell in love. (“Just like me and Hu Jin,” thought Li Fang.) They got married secretly, and they were very happy. (“We could be like that,” thought Li Fang.) When the Goddess of Heaven knew that her granddaughter was married to a human, she became very angry and made the weaving girl return to Heaven. Niu Lang tried to follow her, but the river of stars, the Milky Way, stopped him. Finding that Zhinü was heart-broken, her grandmother finally decided to let the couple cross the Milky Way to meet once a year. Magpies make a bridge of their wings so the couple can cross the river to meet on the seventh day of the seventh lunar month. People in China hope that the weather will be fine on that day, because if it is raining, it means that Zhinü is weeping and the couple won’t be able to meet.The announcer said, “This is the story of Qiqiao Festival. When foreigners hear about the story, they call it a Chinese Valentine’s story. It’s a fine day today, so I hope you can call all meet the one you love.”

As Li Fang set off for home, he thought, “I guess Hu Jin doesn’t love me. I’ll just throw these flowers and chocolates away. I don’t want them to remind me of her.” So he did.

As he sadly passed the tea shop on the corner on his way home, he heard a voice calling him. There was Hu Jin waving at him and calling, “Why are you so late? I’ve been waiting for you for a long time! And I have a gift for you!”

What would he do? He had thrown away her Valentine gifts! She would never forgive him. This would not be a happy Valentine’s Day!Unit 2 Healthy eating

COME AND EAT HERE (I)

Wang Peng sat in his empty restaurant feeling very frustrated. It had been a very strange morning. Usually he got up early and prepared his menu of barbecued mutton kebabs, roast pork, stir-fried vegetables and fried rice. Then by lunchtime they would all be sold. By now his restaurant ought to be full of people. But not today! Why was that? What could have happened? He thought of his mutton, beef and bacon cooked in the hottest, finest oil. His cola was sugary and cold, and his ice cream was made of milk, cream and delicious fruit. “Nothing could be better,” he thought. Suddenly he saw his friend Li Chang hurrying by. “Hello, Lao Li,” he called. “Your usual?” But Li Chang seemed not to hear. What was the matter? Something terrible must have happened if Li Chang was not coming to eat in his restaurant as he always did.

Wang Peng followed Li Chang into a new small restaurant. He saw a sign at the door.Tired of all that fat? Want to lose weight?

Come inside Yong Hui’s slimming restaurant.

Only slimming foods served here.

Make yourself thin again!

Curiosity drove Wang Peng inside. It was full of people. The hostess, a very thin lady, came forward. “Welcome,” she said. “My name is Yong Hui. I’ll help you lose weight and be fit in two weeks if you eat here every day.” Then she gave a menu to Wang Peng. There were few choices of food and drink on it: just rice, raw vegetables served in vinegar, fruit and water. Wang Peng was amazed at this and especially at the prices. It cost more than a good meal in his restaurant! He could not believe his eyes. He threw down the menu and hurried outside. On his way home he thought about his own menu. Did it make people fat? Perhaps he should go to the library and find out. He could not have Yong Hui getting away with telling people lies! He had better do some research!

At the library Wang Peng was surprised to find that his restaurant served far too much fat and Yong Hui’s far too little. Even though her customers might get thin after eating Yong Hui’s food, they were not eating enough energy-giving food to keep them fit. They would become tired very quickly. Wang Peng felt more hopeful as he drove back home. Perhaps with a discount and a new sign he could win his customers back. So he wrote:

Want to feel fit and energetic?

Come and eat here! Discounts today!

Our food gives you energy all day!

The competition between the two restaurants was on!

COME AND EAT HERE (II)

A week later, Wang Peng’s restaurant was nearly full and he felt happier. Perhaps he would be able to earn his living after all and not have to close his restaurant. He did not look forward to being in debt because his restaurant was no longer popular. He smiled as he welcomed some customers warmly at the door but the smile left his face when he saw Yong Hui walking in. She did not look happy but glared at him. “May I ask what you were doing in my restaurant the other day? I thought you were a new customer and now I know that you only came to spy on me and my menu,” she shouted. “Please excuse me,” he calmly explained, “I wanted to know where all my customers had gone last week. I followed one of them and found them in your restaurant. I don’t want to upset you, but I found your menu so limited that I stopped worrying and started advertising the benefits of my food. Why don’t you sit down and try a meal?”

Yong Hui agreed to stay and soon they were both enjoying dumplings and breast of chicken cooked with garlic. When they were served the ice cream, Yong Hui began to look ill. “I feel sick with all this fat and heavy food,” she said, “I miss my vegetables and fruit.” Wang Peng was enjoying a second plate of dumplings so he sighed. “Yes,” he added, “and I would miss my dumplings and fatty pork. Don’t you get tired quickly?” “Well, I do have to rest a lot,” admitted Yong Hui. “But don’t you think it would be better if you were a bit thinner? I’m sure you’d feel much healthier.”

They began to talk about menus and balanced diets. “According to my research, neither your restaurant nor mine offers a balanced diet,” explained Wang Peng. “I don’t offer enough fibre and you don’t offer enough body-building and energy-giving food. Perhaps we ought to combine our ideas and provide a balanced menu with food full of energy and fibre.” So that is what they did. They served raw vegetables with the hamburgers and boiled the potatoes rather than fried them. They served fresh fruit with the ice cream. In this way they cut down the fat and increased the

fibre in the meal. Their balanced diets became such a success that before long Wang Peng became slimmer and Yong Hui put on more weight. After some time the two found that their business cooperation had turned into a personal one. Finally they got married and live happily ever after.

Unit 3 The Million Pound Bank Note

THE MILLION POUND BANK NOTE

Act I, Scene 3

NARRATOR: It is the summer of 1903. Two old and wealthy brothers, Roderick and Oliver, have made a bet. Oliver believes that with a million pound bank note a man could survive a month in London. His brother Roderick doubts it. At this moment, theysee a penniless young man wandering on the pavement outside their house. It is Hey Adams, an American businessman, who is lost in London and does not know what he should do.

RODERICK: Young man, would you step inside a moment, please?

HENRY:Who? Me, sir?

RODERICK: Yes, you.

OLIVER: Through the front door on your left.

HENRY: (a servant opens a door) Thanks.

SERVANT:Good morning, sir. Would you please come in? Permit me to lead the way, sir. OLIVER: (Hey enters) Thank you, James. That will be all.

RODERICK: How do you do, Mr … er …?

HENRY: Adams. Hey Adams.

OLIVER: Come and sit down, Mr Adams.

HENRY: Thank you.

RODERICK: Your are an American?

HENRY: That’s right, from San Francisco.

RODERICK: How well do you know London?

HENRY: Not at all. It’s my first trip here.

RODERICK: I wonder, Mr Adams, if you mind us asking a few questions?

HENRY: Not at all. Go right ahead.

RODERICK: May we ask what you’re doing in this country and what your plans are?

HENRY: Well, I can’t say that I have any plans. I’m hoping to find work. As a matter of fact,

I landed in Britain by accident.

RODERICK: How is that possible?

HENRY: Well, you see, back home I have my own boat. About a month ago, I was sailing

out of the bay … (his eyes stare at what is left of the brothers’ dinner on the table)

OLIVER: Well, go on.

HENRY: Oh, yes. Well, towards nightfall I found myself carried out to sea by a strong wind.

It was all my fault. I didn’t know whether I could survive until morning. The next

morning I’d just about given myself up for lost when I was spotted by a ship.

OLIVER: And it was the ship that brought you to England.

HENRY: Yes. The fact is that I earned my passage by working as an unpaid hand, which

accounts for my appearance. I went to the American embassy to seek help, but …

(the brothers smile at each other)

RODERICK: Well, you mustn’t worry about that. It’s an advantage.

HENRY: I’m afraid I don’t quite follow you, sir.

RODERICK: Tell us, Mr Adams, what sort of work did you do in America?

HENRY: I worked for a mining company. Could you offer me some kind of work here? RODERICK: Patience, Mr Adams. If you don’t mind, may I ask how much money you have? HENRY: Well, to be honest, I have none.

RODERICK: (happily) What luck! Brother, what luck! (claps his hands together)

HENRY: Well, it may seem lucky to you but not to me! On the contrary, in fact. If this is

your idea of some kind of joke, I don’t think it’s very funny. (Hey stands up to

leave) Now if you’ll excuse me, I think I’ll be on my way.

RODERICK: Please don’t go Mr Adams. You mustn’t think we don’t care about you. Oliver, give

him the letter.

OLIVER: Yes, the letter. (gets it from a desk and gives it to Hey like a gift) The letter. HENRY: (taking it carefully) For me?

RODERICK: For you. (Hey starts to open it) Oh, no, you mustn’t open it. Not yet. You can’t

open it until two o’clock.

HENRY: Oh, this is silly.

RODERICK: Not silly. There’s money in it. (calls to the servant) James?

HENRY: Oh, no. I don’t want your charity. I just want an honest job.

RODERICK: We know you’re hard-working. That’s why we have given you the letter. James,

show Mr Adams out.

OLIVER: Good luck, Mr Adams.

HENRY: Well, why don’t you explain what this is all about?

RODERICK: You’ll soon know. (looks at the clock) In exactly an hour and a half.

SERVANT:This way, sir.

RODERICK: Mr Adams, not until 2 o’clock. Promise?

HENRY: Promise. goodbye.

Unit 4 Astronomy: the science of the stars

HOW LIFE BEGAN ON THE EARTH

No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a “Big Bang” that threw matter in all directions. After that, atoms began to form and combine to create stars and other bodies.

For several billion years after the “Big Bang”, the earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon dioxide, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.
