1、Unit 1 Fog Fog warning When Polly left home that morning, the city was already covered in a grey mist. At lunch, the radio forecast that the mist would become a thick fog in the afternoon. At four o'clock, Polly left work and stepped out into the fog .She wondered if the buses would still be runn
2、ing. No buses to King Street Once out in the street, she walked quickly towards her usual bus stop. ‘How far are you going?’ the bus conductor asked her before he took her fare. ‘King Street.’ said Polly. ‘Sorry,Miss’ replied the man, ‘the truth is that it is too foggy for the bus to run that f
3、ar. Take the Underground to Green Park. The weather might be better there and you might be able to get a taxi.’ A tall man As Polly observed the passengers on the train, she had a feeling that she was being watched by a tall man in a dark overcoat. At last the train arrived at Green Park station.
4、While the rest of the passengers were getting out, she glanced at the faces around her. The tall man was nowhere to be soon. Footsteps When Polly got to the station entrance, it was empty. Outside, wherever she looked the fog lay like a thick, grey cloud. There was no one in sight. Polly set off t
5、owards Park Street. As she walked along the narrow street, she heard the sound of footsteps approaching, but by the time she reached the corner of the street, the foot steps were gone. Suddenly Polly felt a rough hand brush her cheek, and she heard a man’s voice in her ear saying ‘Sorry.’ The man mo
6、ved away. She could feel her heart beating with fear. The helpful stranger Then she heard the sound again-soft footsteps behind her. A minute before, she had wished for someone to come along. Now she wanted to run, but fear held her still. The footsteps seemed close now. Then a man’s voice came ou
7、t of the darkness. ‘Is anybody there?’ Polly hesitated. At last she answered, ‘Hello, I think I’m lost. ’ A few seconds later, a hand reached out and grasped her arm. Polly found herself staring up at the face of an old man with a beard. ‘Maybe I can help you. Which road do you want?’ he asked.
8、‘I live at 86 King Street.’ Polly replied. ‘Just take my hand.’ said the man. ‘Come with me. You’ll be all right.’ He took Polly’s hand. ‘Watch out for the step here.’ In his other hand the man carried a stick. Polly heard it hit the step. ‘I can remember some terrible fogs, but maybe that was bef
9、ore your time. I can’t see your face, but you sound young. How old are you?’ ‘Just twenty.’ answered Polly. ‘Ah, twenty ! A nice age to be. I was young once. Now we’re at the crossroads. Turn left here.’ ‘I’m quite lost now. Are you sure you know the way?’ Polly was beginning to feel frightened a
10、gain.’ ‘Of course. You really shouldn’t feel anxious,’ He held her hand more firmly. The grateful helper ‘Here we are. King Street.’ He stopped. ‘Thank you so much for coming to my aid.’ said Polly in relief. ‘Would you like to come in and rest for a while?’ ‘It’s very nice of you.’ said the ma
11、n, ‘but I’ll be off. There may be more people lost today, and I’d like to help them. You see, a fog this bad is rare. It gives me the chance to pay back the help that people give me when it’s sunny. A blind person like me can’t get across the road without help, except in a fog like this.’ Project
12、 (P18) Shark attacks There are nearly 400 different types of sharks, but only about 30 types are known to have attacked human beings. Many people know that the most dangerous shark is the great white shark, probably because they have seen the film Jaws. However, two other sharks are also rather
13、dangerous: the tiger shark and the bull shark. Contrary to what many people might assume, evidence shows that sharks seldom attack humans. There are three types of shark attacks. In the main type, the shark attacks you because it mistakes you for a fish, but when it tastes human flesh it decides to
14、 give up and swims away. In the second type, the shark pushes you with its nose to find out if you are fit to be eaten, and then bites you if it thinks you are. In the third type, the shark waits for you to swim by, and then attacks you suddenly. The last two types of attack more often result in the
15、 death of humans. To reduce the risk of a shark attack, you should follow these suggestions. Do not swim in the dark. Sharks can still see you but you cannot see them. Do not go swimming in the ocean if you have a fresh wound. Sharks can smell blood over a long distance. Do not wear bright cloth
16、ing or jewellery, because sharks are attracted to the flash of, colours and bright objects. Stay in groups, as sharks usually avoid large numbers of people. Recently, shark attacks have been increasing as water sports are becoming more popular. If a shark attacks you, follow the advice below. Keep
17、 calm. Do not panic. Hit the shark on the nose with your fist. Stick your finger in the shark's eye. Don't be frightened by sharks: you are 3o times more likely to be hit by lightning than be attacked by a shark. The wonderful world of pigeons It is night. All is quiet. The soldiers are asleep
18、while a guard watches for the enemy. There is a flash, and the sound of guns! They are being attacked! Hundreds of enemy soldiers rush towards them. They are all going to be killed unless they get help. What should they do? An officer writes a short message quickly on a small piece of paper: 'Being
19、 attacked! Hurry!' He rolls up the paper and puts it into a small case, and then reaches into a cage and gets a bird. Attaching the message to its leg, he sets the bird loose. It immediately flies into the air and disappears in the dark. Will the bird arrive in time? Will they be saved? Though it
20、 may seem hard to believe, the bird the officer uses is the same bird often seen in public parks--the pigeon. Pigeons have a wonderful sense of direction and can find their way home over long distances. Indeed, pigeons have been known to fly home from as far away as 1,800 kilometres. That is why pig
21、eons have been used since ancient times to carry the news or even the mail. However, it was in war that they found their greatest use. During both World War I and II, pigeons were employed by armies to carry messages to and from the front lines, saving the lives of many soldiers and even helping win
22、 some important victories. How do pigeons find their way? Pigeons appear to have a compass inside them that tells them which way is north. How this compass works remains a mystery. Of course, since a compass alone is not enough to find one's way, they also appear to use their sight and even their s
23、ense of smell to tell them which way they should go. Unlike humans, they never get lost and can always find their way home. Unit 2 English and its history All through history, people from many different countries and cultures have lived together in Britain. The English language is made up of
24、 the grammar and vocabulary these people brought to Britain. That is why English has so many difficult rules that confuse people. Old English Old English is very different from the English we speak nowadays. In fact, we would not be able to understand it if we heard it today. Before the middle of
25、the 5th century, people in Britain all spoke a language called Celtic. Then two Germanic groups from the European mainland—the Angles and the Saxons—occupied Britain. Old English consisted of a mixture of their languages. (Both the English language and the English people are named after the Angles;
26、the word Angle was spelt Engle in Old English.) Aside from place names such as London, very few Celtic words became part of Old English. At the end of the 9th century, the Vikings, people from Northern European countries such as Denmark and Norway, began to move to Britain. They brought with them th
27、eir languages, which also mixed with Old English. By the 10th century, Old English had become the official language of England. When we speak English today, we sometimes feel puzzled about which words or phrases to use. This is because English has many words and phrases from different languages, bu
28、t with similar meanings. For example, the word sick came from a word once used by the Angles and the Saxons, while ill came from a word once used by the Norwegians. Middle English Middle English is the name given to the English used from around the 12th to the 15th centuries. Many things played a
29、part in the development of this new type of English. The most important contribution was from the Normans, a French-speaking people who defeated England and took control of the country in 1066. However, the Norman Conquest did not affect English as mush as the Angles and the Saxons’ victory about 60
30、0 years earlier, which led to Old English replacing Celtic. Even though the Normans spoke French for the entire 250 years they ruled England, French did not replace English as the first language. On the other hand, the English language did borrow many words from French. This resulted in even more wo
31、rds with similar meanings, such as answer (from Old English) and reply (from Old French). It is interesting to learn how the words for animals and meat developed. After the Norman Conquest, many English people worked as servants who raised animals. Therefore, the words for most animals raised for fo
32、od, such as cow, sheep and pig, came from Old English. However, the words for the meat of these animals, which was served to the Normans, came from Old French: beef, mutton, pork and bacon. Old French made other contributions to Middle English as well. In Old English, the Germanic way of making wor
33、ds plural was used. For example, they said housen instead of houses, and shoen instead of shoes. After the Normans took control, they began using the French way of making plurals, adding an -s to house and shoe. Only a few words kept their Germanic plural forms, such as man/men and child/children.
34、After the Norman Conquest, high-class people spoke French while common people spoke English. However, by the latter half of the 14th century, English had come into widespread use among all classes in England. In 1399, Henry Ⅳ became King of England. His mother tongue was English, and he used English
35、 for all official events. Modern English Modern English appeared during the Renaissance in the 16th century. Because of this Modern English includes many Latin and Greek words. Pronunciation also went through huge changes during this period. Of course, this was not the end of the changes in the En
36、glish language. The question of whether English will keep on changing in the future is easy to answer. It is certain that this process will continue, and people will keep inventing new words and new ways of saying things. Project The development Chinese characters The Chinese language differs f
37、rom Western languages in that, instead of an alphabet, it uses characters which stand for ideas, objects or deeds. Chinese words are formed by putting together different characters. In many cases, a single character can also make up a word. The history of the Chinese language can be examined by look
38、ing at how these characters developed. Chinese writing began thousands of years ago. According to an ancient story, a man named Cang Jie invented Chinese writing. One winter day while he was hunting, he saw the tracks of animals in the snow and observed that the appearance of each one was different
39、 Then he had the idea that he could use different shapes to represent different objects. The first Chinese characters were drawings of physical objects. Some characters have been simplified and others have been made more difficult over time. However, as a whole, the characters have developed from
40、drawings into standard forms. The character for a mountain was at first three mountaintops together. This became one mountaintop and three lines, and over time turned into the character used nowadays. Not all characters were developed from drawings of objects. Sometimes to express ideas, some chara
41、cters were made by combining two or more characters together. For example, 'rest' was made up of the characters for a man and a tree. The character 'prisoner' was formed with a 'man' inside a square. Other characters were developed for directions and numbers. It is easy to distinguish their meanings
42、 by looking at them, for example, the characters for 'up' and 'down', which are opposites of each other. Though these kinds of characters indicate meanings, one of their shortcomings is that they do not show how they should be pronounced. Therefore, a method was developed to have one part of a char
43、acter indicate the meaning and the other suggest the pronunciation. Many Chinese characters used today were made this way. In the 1950s the Chinese government introduced simplified Chinese characters and now they have widespread use in China's mainland. The story of Braille Usually, when we talk
44、about reading, we think of using our eyes to see letters written in ink on paper. However, this is not always true. For example, blind people cannot see, but they can still read books. The man who introduced blind people to reading was Louis Braille (1809-1852). Braille lost his eyesight at the age
45、 of three as a result of an injury. When he was ten, he went to a school for the blind in Paris. In those days, books for blind people used paper pressed against metal wire to form letters. Since the metal wire was heavy, each book weighed as much as 100 pounds. The whole system was not convenient f
46、or use. Indeed, the school library only had fourteen such books in it. In 1821, a soldier visited the school and showed the students a system for passing messages at night during times of battle. His system used paper with small, raised dots that could be felt with the fingers. Each letter of the al
47、phabet was represented by a different pattern which consisted of twelve dots. The soldiers would drag their fingers over the raised dots to read the message. While the students found the soldier's idea interesting, the system was too difficult to be of practical use. However, young Louis Braille too
48、k the idea and worked on it. At the age of fifteen, he created a system with patterns of six raised dots representing each letter. 'Braille', the system for reading used today by blind people around the world, was thus born. The blind can easily recognize Braille with the fingers. They can also eas
49、ily write in Braille with a special typewriter. Today, it is the most common system used by blind people for reading and writing, and nearly every language, including Chinese, has its own version of Braille for its people to use. Unit 3 Lost civilizations Day 1, 15 July I feel lucky to have
50、won a place on this trip. We are in Italy now, and tomorrow we are visiting Pompeii. Next week we are flying to China, and going to Loulan, which is known as China’s Pompeii in the desert. Both Pompeii and Loulan became lost civilizations long ago. Day 2, 16 July This morning we attended a lecture
