Argentina is famous for the tango. The U.S.A.is known for jazz,the type of music that has gained worldwide popularity. Jazz is an American contribution to popular music. While classical music follows formal European tradition,jazz is rather a free form. It is full of energy,expressing the moods,interests,and emotions of the people. It is breaking and exciting with a modern sound. In the 1920s jazz sounded like America. And so it does today. The origins of the music are as interesting as the music itself. Jazz was invented by American Negroes,or blacks,as they are called today,who were brought to the southern states as slaves. They were sold to farm owners and forced to work long hours in the cotton and tobacco fields. This work was hard and life was short. When a Negro died his friends and s would gather and carry the body to have a ceremony before they buried him. There was always a band with them. On the way to the ceremony the band played slowly,solemn music suitable for the situation. But on the way home the mood changed. Spirits lifted. Everyone was happy. Death had removed one of their members,but the living were glad to be alive. The band played happy music. This music made everyone want to dance. It was an early form of jazz. Music has always been important in Negro life. The black,who were brought to American from West Africa,had a rich musical tradition. In the fields,they made up work songs. Singing made the hard work go faster. And when they got to Christianity,they made lovely spirituals,which have become an everlasting part of American music. Question: From the passage,we can see that jazz _ . Options: A: is a kind of African music B: started from Africa but is popular in America C: was started by blacks working in Africa D: was started by blacks in America

Read the article and select the best answer. Article: An old and very rich friend of mine told me he had an unpleasant experience. He went to a famous jewelry shop and asked to be shown some gold necklaces. After examining several minutes, he decided to buy a gold necklace with a precious diamond, and asked if he could pay by cheque . The assistant said that was quite in order, but the moment my friend signed his name, he was invited into the manager's office. The manager was very polite, but he explained that someone with exactly the same name had given them a worthless cheque not long ago. My friend got very angry when he heard this and said that he would buy a diamond necklace somewhere else. When he got up to go, the manager told him that the police would arrive at any moment and he had better stay unless he wanted to get into serious trouble. Sure enough, the police arrived soon afterwards. They were polite, too, but explained that a person who had used the same name as his was responsible for a number of recent robberies. Then the police asked my friend to copy out a note which had been used by the thief in a number of stores. The note read, "I have a gun in my pocket. Ask no question and give me all the money in the drawer." Luckily, my friend's handwriting was quite unlike the thief's. He was not only allowed to go without further delay,but also to take the diamond necklace with him. Question: The police were polite, too, because _ . Options: A: they didn't think the man was a thief B: the man was old and very rich C: they were not sure whether the man was the thief they wanted D: they doubted that the man was responsible for a number of recent robberies

Ques: Read the article and select the best answer. Article: A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature. The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming. Another source of carbon dioxide comes from _ . In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects. Sophie Armstrong, the writer of Earth Care put it, "There's no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon. Question: Which of the following titles goes with the text? Options: A: A Rising Population B: Saving Sources of Energy C: Global warming: The causes D: Carbon Dioxide
Ans: C

Ques:Read the article and select the best answer. Article: A blue hole is a flooded sea cave with a hole that opens up at the land's surface. These cave systems form in carbonate rock, often on islands. Some blue holes have very special rock formations and water chemistry. Far below sea level, they contain some of the harshest environments on Earth, with no oxygen and no light. Yet these areas are filled with life forms that have adapted to the extreme conditions. Information gathered from these blue holes is helping scientists to increase their understanding of biology, archaeology and geology. But exploring these blue hole environments brings danger as well as discovery. Blue holes get their name from the color1 some have when seen from the air. The color1 is usually a reflection of the sky on the water. But not all of these cave systems have blue surfaces. Some contain dark or muddy water. Blue holes are the result of erosion in which water breaks down rock. Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass. These holes were later filled with sea water as the sea level changed. The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations. Blue holes are vertical caves. But they can also have horizontal cave formations that may be hundreds of meters long. These flooded cave systems can be found in the ocean, or they can be found inland. Ocean caves are affected by tides, so they always have water movement. But blue holes on land are very still. They have several layers of water, chemicals, and bacteria. The top layer of fresh water comes from rainfall. This layer acts like a cap on top of the layered mixture, and keeps out oxygen from the atmosphere. The fresh water floats on a denser layer of saltwater. Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water. Underneath this layer is anoxic seawater -- water that does not contain any oxygen. Underwater caves are probably one of the least explored ecosystems... Question: When exploring blue holes, divers must _ . Options: A: have a thin rope as a guideline anytime B: wear glasses in case of bright blue light C: swim as quickly as possible to save time D: learn to make good use of their air supply

Ans:
D
