教材练习答案及听力原文 Unit 1 WARMING UP ?Answers: 1 Archimedes, Ancient Greek (287-21 2 BC) He was a mathematician. He found that if you put an object into water the water pushes the object up. It rises and partly floats. The force of the water pushing it up is the same as the weight of the object. 2 Charles Darwin, British (1808-1882) The Origin of Species was published in 1859. It explained how plants and animals had changed over time to fit in with a changing environment. At the time it was published it was very controversial. Many people believed the Bible when it said that God made the first two people (Adam and Eve) and that all other people came from these two. Darwin’s book showed that people had developed from apes instead. So this caused a lot of ar gument between religious and scientific people. However Darwin’s idea became very influential and is still accepted today. 3 Thomas Newcomen, British (1663-1729) He improved the first steam pump built by Thomas Savery in 1698 and turned it into a steam engine for taking water out of mines in 1712. James Watt improved it still further in the 1770s turning it into the first modern steam engine used on the railways. 4 Gregor Mendel, Czech (1822-1884) He grew pea plants and developed ideas on heredity and inherited characteristics. He concentrated on cross-fertilising pea plants and analyzing the results. Between 1856-1863 he grew 28,000 pea plants. He examined seven kinds of seed and plant characteristics and developed some laws of inheritance. The first is that inheritance factors do not combine but are passed to the next generation intact. Second, he found that each partner gives half the inherited factors to the young. Third, some of these factors show up in the offspring (and so are dominant). The other factors are masked by the dominant ones (and so are recessive). 5 Marie Curie, Polish and French (1867-1934) She was born in Poland and came to study in France in 1891 and she lived there for the rest of her life. In 1898 she discovered radium. She received two Nobel prizes, one (with Pierre Curie) for physics (1903) and one for chemistry (1911). She is the only person to have been so honoured. On the death of her husband she took over his job at the Sorbonne in Paris. Her work on radioactivity and the discovery of radium meant that she began a new scientific area of research. She was the first woman to receive a Nobel Prize and the first woman to teach at the Sorbonne. 6 Thomas Edison, American (1847-1931) He was already an inventor of other electrical devices (phonograph, electric light bulb) when in 1882 he designed a system for providing New York with electricity from a central power station. This was a tremendous achievement, which had previously been thought impossible.

But he became inspired when he tho ught about helping ordinary people exposed to cholera. This was the deadly dise ase of its day. Neither its cause nor its cure was understood. So many thousand s of terrified people died every time there was an outbreak. John Snow wanted t o face the challenge and solve this problem. He knew that cholera would never b e controlled until its cause was found. He became interested in two theories that possibly explained how cholera ki lled people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person die d. John Snow suspected that the second theory was correct but he needed eviden ce. So when another outbreak hit London in 1854, he was ready to begin his enqu iry. As the disease spread quickly through poor neighbourhoods, he began to gat her information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why. First he marked on a map the exact places where all the dead people had liv ed. This gave him a valuable clue about the cause of the disease. Many of the d eaths were near the water pump in Broad Street (especially numbers 16, 37, 38 a nd 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame. Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. H e immediately told the astonished people in Broad Street to remove the handle f rom the pump so that it could not be used. Soon afterwards the disease slowed d own. He had shown that cholera was spread by germs and not in a cloud of gas. In another part of London, he found supporting evidence from two other deat hs that were linked to the Broad Street outbreak. A woman, who had moved away f rom Broad Street, liked the water from the pump so much that she had it deliver ed to her house every day. Both she and her daughter died of cholera after drin king the water. With this extra evidence John Snow was able to announce with ce rtainty that polluted water carried the virus.

-必修 5 Unit 2 The United Kingdom Reading PUZZLES IN GEOGRAPHY People may wonder why different words are used to describe these four countries: England, Wales, Scotland and Northern Ireland. You can clarify this question if you study British history. First there was England. Wales was linked to it in the thirteenth century. Now when people refer to England you find Wales included as well. Next England and Wales were joined to Scotland in the seventeenth century and the name was changed to "Great Britain". Happily this was accomplished without conflict when King James of Scotland became King of England and Wales as well. Finally the English government tried in the early twentieth century to form the United Kingdom by getting Ireland connected in the same peaceful way. However, the southern part of Ireland was unwilling and broke away to form its own government. So only Northern Ireland joined with England, Wales and Scotland to become the United Kingdom and this was shown to the world in a new flag called the Union Jack. To their credit the four countries do work together in some areas (eg, the currency and international relations), but they still have very different institutions. For example, Northern Ireland, England and Scotland have different educational and legal systems as well as different football teams for competitions like the World Cup! England is the largest of the four countries, and for convenience it is divided roughly into three zones. The zone nearest France is called the South of England, the middle zone is called the Midlands and the one nearest to Scotland is known as the North. You find most of the population settled in the south, but most of the industrial cities in the Midlands and the North of England. Although, nationwide, these cities are not as large as those in China, they have world-famous football teams and some of them even have two! It is a pity that the industrial cities built in the nineteenth century do not attract visitors. For historical architecture you have to go to older but smaller towns built by the Romans. There you will find out more about British history and culture. The greatest historical treasure of all is London with its museums, art collections, theatres, parks and buildings. It is the centre of national

外研社必修五课文reading-原文

Module 1 British and American English Words, words, words British and American English are different in many ways. The first and most obvious way is in the vocabulary. There are hundreds of different words which are not used on the other side of the Atlantic, or which are used with a different meaning. Some of these words are well known — Americans drive automobiles down freeways and fill up with gas; the British drive cars along motorways and fill up with petrol. As a tourist, you will need to use the underground in London or the subway in New York, or maybe you will prefer to get around the town by taxi (British) or ca b (American). Chips or French fries? But other words and expressions are not so well known. Americans use a flashlight, while for the British, it's a torch. The British queue up; Americans stand in line. Sometimes the same word has a slightly different meaning, which can be confusing. Chips, for example, are pieces of hot fried potato in Britain; in the States chips are very thin and are sold in packets. The British call these crisps. The chips the British know and love are French fries on the other side of the Atlantic. Have or have got? There are a few differences in grammar, too. The British say Have you got ...? while Americans prefer Do you have ...? An American might say My friend just arrived, but a British person would say My friend has just arrived. Prepositions, too, can be different: compare on the team, on the weekend (American) with in the team, at the weekend (British). The British use prepositions where Americans sometimes omit them (I'll see you Monday; Write me soon!). Colour or color? The other two areas in which the two varieties differ are spelling and pronunciation. American spelling seems simpler: center, color and program instead of centre, colour and programme. Many factors have influenced American pronunciation since the first settlers arrived four hundred years ago. The accent, which is most similar to British English, can be heard on the East Coast of the US. When the Irish writer George Bernard Shaw made the famous remark that the British and the Americans are two nations divided by a common language, he was obviously thinking about the differences. But are they really so important? After all, there is probably as much variation of pronunciation within the two countries as between them. A Londoner has more difficulty understanding a Scotsman from Glasgow than understanding a New Yorker. Turn on the TV Some experts believe that the two varieties are moving closer together. For more than a century communications across the Atlantic have developed steadily. Since the 1980s, with satellite TV and the Internet, it has been possible to listen to British and American English at the flick of a switch. This non-stop communication, the experts think, has made it easier for British people and Americans to understand each other. But it has also led to lots of American words and structures passing into British English, so that some people now believe that British English will disappear. However, if you turn on CNN, the American TV network, you find newsreaders and weather forecasters all speaking with different accents — American, British, Australian, and even Spanish. One of the best-known faces, Monita Rajpal, was born in Hong Kong, China, and grew up speaking Chinese and Punjabi, as well as English. This international dimension suggests that in the future, there are going to be many "Englishes", not just two main varieties. But the message is "Don't worry." Users of English will all be able to understand each other — wherever they are.
