As there are so many different styles of Western art, it would be impossible to describe all of them in such a short text. Consequentl
2、y, this text will describe only the most important ones. Starting from the sixth century AD. The Middle Ages(5th to the 15th century AD) During the Middle Ages, the main aim of painters was to represent religious themes. A conventional artistof this period was not interested in showing nature and pe
3、ople as they really were. A typical picture at this time was full of religious symbols, which created a feeling of respect and love for God. But it was evident that ideas were changing in the 13th century when painters like Giotto di Bondone began to paint religious scenes in a more realistic way. T
4、he Renaissance(15th to 16th century) During the Renaissance, new ideas and values gradually replaced those held in the Middle Ages. People began to concentrate less on religious themes and adopt a more humanistic attitude to life.At the same time painters returned to classical Roman and Greek ideas
5、about art. They tried to paint people and nature as they really were. Rich people wanted to possess their own paintings, so they coule decorate their superb palaces and great houses. They paid famous artists to paint pictures of themselves, their houses and possessions as well as their activities an
6、d achievements. One of the most important discoveries during this period was how to draw things in perspective. This technique was first used by Masaccio in 1428. When people first saw his paintings, they were convinced that they were looking through a hole in a wall at a real scene. If the rules of
7、 perspective had not been discovered, no one would have been able to paint such realistic pictures. By coincidence,oil paints were also developed at this time, which made the colours used in paintings look richer and deeper. Without the new paints and the new technique, we would not be able to see t
8、he many great masterpieces for which this period is famous. Impressionism(late 19h to early 20th century) In the late 19th century, Europe changed a great deal,from a mostly agricultural society to a mostly industrial one. Many people moved from the countryside to the new cities. There were many new
9、 inventions and social changes also led to new painting styles. Among the painters who broke away from the traditional style of painting were the Impressionists, who lived and worke in Paris. The Impressionists were the first painters to work outdoors. They were eager to show how light and shadow fe
10、ll on objects at different times of day. However, because natural light changes so quickly, the Impressionists had to paint quickly. Their paintings were not as detailed as those of earlier painters. At first, many people disliked this style of painting and became very angry about it. They said that
11、 the painters were careless and their paintings were ridiculous. Modern Art(29th century to today) At the time they were created, the Impressionist paintings were controversial, but today they are accepeted as the beginning of what we call “modern art”. This is because the Impressionists encouraged
12、artists to look at their environment in new ways. There are scores of modern art styles,but without the Impressionists, many of these painting styles might not exsist. On the one hand, some modern art is abstract; that is, the painter does not attempt to paint objects as we see them with our eyes, b
13、ut instead concentrates n certain qualities of the object, using colour, line and shape to represent them. On the other hand, some paintings of modern art are so realistic that they look like photographs. These styles are so different. Who can predict what painting styles there will be in the future
14、?Unit 3It is a beautiful day here and I am sitting under the big tree at the end of the garden. I have just returned from a long bike ride to an old castle. It seems amazing that at my age I am still fit enough to cycle 20 kilometres in an afternoon.Its my birthday in two weeks time and I ll be82yea
15、rs old! I think my long and active life must be due to the healthy life I live. This brings me to the real reason for my letter, my dear grandson. Your mother tells me that you started smoking some time ago and how you are finding it difficult to give it up. Believe me, I know how easy it is to begi
16、n smoking and how tough it is to stop. You see, during adolescence I also smoked and became addicted to cigarettes. By the way, did you know that this is because you become addicated in three different ways. First, you can become physically addicated to nicotine, which is one of the hundreds of chem
17、icals in cigarettes. This means that after a while your body becomes accustomed to having nicotine in it. So when the drug leaves our body, you get withdrawal symptoms. I remember feeling bad-tempered and sometimes even in pain. Secondly, you become addicted through habit. As you know, if you do the
18、 same thing over and over again, you begin to do it automatically.Lastly, you can become mentally addicted. I believed I was happier and more relaxed after having a cigarette, so I began to that I could only feel good when I smoked. I was addicted in all three ways, so it was very difficult to quit.
19、 But I did finally manage. When I was young, I didnt know much about the harmful effects of smoking. I didnt know, for example, that it could do terrible damage to your heart and lungs or that it was more difficult for smoking couples to become pregnant. I certainly didnt know their babies may have
20、a smaller birth weight or even be abnormal in some way. Neither did I know that my cigarette smoke could affect the health of non-smokers. However, what I did know was that my girlfriend thought I smelt terrible. She said my breath and clothes smelt, and that the ends of my fingers were turning yell
21、ow. She told me that she wouldnt go out with me again unless I stopped! I also noticed that I became breathless quickly, and that I wasnt enjoying sport as much. When I was taken off the school football team because I was unfit, I knew it was time t quit smoking. I am sending you some advice I found
22、 on the Internet It might help you to stop and strengthenyour resolve. I do hope so because I want you to live as long and healthy a life as I have. Love from GrandadUnit 4 THE EARTH IS BECOMIG WARMER-BUT DOES IT MATTER?During the 20th century the temperature of the earth rose about one degree Fahre
23、nheit. That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes. So how has this come about and does it matter? Earth cares Sophie Armstrong explores these questions. There is no doubt that the earth is becoming warmer(see Graph 1) and that it
24、is human activity that has caused this global warmig rather than a random but natural phenomenon. All scientists subscribe to the view that the increase in the earths temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process a
25、re called “greenhouse” gases, the most important one of which is carbon dioxide. Dr Janice Foster explains: “There is a natural phenomenon that scientists call the “greenhouse effect”.This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from
26、 the sun and therefore warm the earth. Without thegreenhouse effect the earth would be about thirty-three degrees Celsciu cooler than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be
27、 trapped in the atmosphere causing the global temperature to go up. We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 t
28、o 1997. He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million(see Graph 2) All scientists accept this data. They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon
29、 dioxide. So how high will the temperature increase go? Dr Janice Foster says that over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius, but it could be as high as 5 degrees. However, the attitude of scientists towards this rise in completely different. On the on
30、e hand, Dr Foster thinks that the trend which increases the temperature by 5 degrees would be a catastrophe. She says, “ We cant predict the climate well enough to know what to expect, but it could be very serious.” Others who agree with her think there may be a rise of several metres in the sea lev
31、el, or predict severe storms, floods, droughts, famines, the spread of diseases and the disappearance of species. On the other hand, there are those, like George Hambley, who are opposed to this view, believe that we should not worry about high levels of carbon dioxide in the air. They predict that
32、any warming will be mild with few bad environmental consequences. In fact, Hambley states, “More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will encourage a greater range of animals-all of which will make life for human beings better.”
33、Greenhouse gases continue to build up in the atmosphere. Even if we start reducing the amount of carbon dioxide and other greenhouse gases, the climate is going to keep on warming for decades or centuries. No one knows the effects of global warming. Does that mean we should do nothing? Or, are the r
34、isks too great?Unit 5AN EXCITING JOB I have the greatest job in the world. I travel to unusual places and work alongside people from all over the world. Sometimes working outdoors, sometimes in an office, sometimes using scientific equipment and sometimes meeting local people and tourists, I am neve
35、r bored. Although my job is occasionally dangerous, I dont mind because danger excites me and makes me feel alive. However, the most important thing about my job is that I help protect ordinary people from one of the most powerful forces n earth-the volcano. I was appointed as volcanologist informat
36、ion for a database about Mount Kilauea, which is one of the most active volcanoes in Hawaii. Having collected and evaluated the information, I help other scientists to predict where lava from the volcano will flow next and how fast. Our work has saved man lives because people in the path of the lava
37、 can be warned to leave their houses. Unfortunately, we cannot move their homes out of the way, and many houses have been covered with lava or burned to the ground. When boiling rock erupts from a volcano and crashes back to earth, it causes less damage than you might imagine. This is because no one
38、 lives near the top of Mount Kilauea, where the rocks fall. The lava that flows slowly like a wave down the mountain causes far more damage because it buries everything in its path under the molten rock. However, the eruption itself is really exciting to watch and I shall never forget my first sight
39、 of one. It was in the second week after I arrived in Hawaii. Having worked hard all day, I went to bed early. I was fast asleep when suddenly my bed began shaking and I heard a strange sound, like a railway train passing my window. Having experienced quite a few earthquakes in Hawaii already, I did
40、nt take much notice. I was about to go back to sleep when suddenly my bedroom became as bright as day. I ran out of the house into the back garden where I could see Mount Kilauea in the distance. There had been an eruption from the side of the mountain and red hot lava was fountaining hundreds of me
41、tres into the air. It was an absolutely fantastic sight. The day after this eruption I was lucky enough to have a much closer look at it. Two other scientists and I were driven up the mountain and dropped as close as possible to the crater that had been formed duing the eruption. Having earlier coll
42、ected special clothes from the observatory, we put them on before we went any closer. All three of us looked like spacemen. We had white protective suits that covered our whole body, helmets,big boots and special gloves. It was not easy to walk in these suits, but we slowly made our way to the edge
43、of the crater and looked down into the red, boiling centre. The other two climbed down into the crater to collect some lava for later study, but this being my first experience, I stayed at the top and watched them. Today, I am just as enthusiastic about my job as the day I first started. Having studied volcanoes now for many years, I am still amazed their beauty as well as their potential to cause great damage. 版权所有中国教育考试资源网
