Read the following passage and mark the letter A, B,C, or D on your answer sheet to indicate the correct answer to each of the questions from 39 to 48.The medieval artists didn't know about perspective; they didn't want to make their people look like real, individual people in a real, individual scence. They wanted to show the truth, the eternal quality of their religious stories. So these artists didn't need to know about perspective.In the European Renaissance period, artists wanted to show the importance of the individual person and his or her possessions and surroundings. A flat medieval style couldn't show this level of reality and the artists needed a new technique. It was the Italian artist Brunelleschi who discovered the technique of perspective drawing. At first the artists of the Renaissance only had single- point perspective. Later they realized that they could have two- pointed perspective and still later multi- point perspective.With two- point perspective they could turn an object (like a building) at an angle to the picture and draw two sides of it. The technique of perspective which seems so natural to us now is an invented technique, a part of the "Grammar of painting" . Like all bits of grammar there are exceptions about perspective. For example, only vertical and horizontal surfaces seem to meet on eye level. Sloping roof tops don't meet on eye level.For 500 years, artists in Europe made use of perspective drawing in their pictures. Nevertheless, there are a range of priorities that artists in displaying individual styles. Crivelli wanted to show depth in his picture and he used a simple single - point perspective. Cezanne always talks about space and volume .Van Gogh, like some of the other painters of the Impressionist period, was interested in Japanese prints. And Japanese artists until this century were always very strong designers of "flat" pictures. Picasso certainly made pictures which have volume and depth. However, he wanted to keep our eyes on the surface and to remind us that his painting are paintings and not illusions.It is technically easy to give an illusion of depth. However, a strong two dimensional design is just as important as a feeling of depth, and perhaps more important.The word "illusion" in paragraph five is closest in meaning to_________ .

Read the following passage and mark the letter A, B,C, or D on your answer sheet to indicate the correct answer to each of the questions from 39 to 48.The medieval artists didn't know about perspective; they didn't want to make their people look like real, individual people in a real, individual scence. They wanted to show the truth, the eternal quality of their religious stories. So these artists didn't need to know about perspective.In the European Renaissance period, artists wanted to show the importance of the individual person and his or her possessions and surroundings. A flat medieval style couldn't show this level of reality and the artists needed a new technique. It was the Italian artist Brunelleschi who discovered the technique of perspective drawing. At first the artists of the Renaissance only had single- point perspective. Later they realized that they could have two- pointed perspective and still later multi- point perspective.With two- point perspective they could turn an object (like a building) at an angle to the picture and draw two sides of it. The technique of perspective which seems so natural to us now is an invented technique, a part of the "Grammar of painting" . Like all bits of grammar there are exceptions about perspective. For example, only vertical and horizontal surfaces seem to meet on eye level. Sloping roof tops don't meet on eye level.For 500 years, artists in Europe made use of perspective drawing in their pictures. Nevertheless, there are a range of priorities that artists in displaying individual styles. Crivelli wanted to show depth in his picture and he used a simple single - point perspective. Cezanne always talks about space and volume .Van Gogh, like some of the other painters of the Impressionist period, was interested in Japanese prints. And Japanese artists until this century were always very strong designers of "flat" pictures. Picasso certainly made pictures which have volume and depth. However, he wanted to keep our eyes on the surface and to remind us that his painting are paintings and not illusions.It is technically easy to give an illusion of depth. However, a strong two dimensional design is just as important as a feeling of depth, and perhaps more important.The following artists' priorities in style shift away from perspective EXCEPT _________.

Read the passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.In the world today, particularly in the two most industrialized areas, North America and Europe, recycling is big news. People are talking about it, practicing it, and discovering new ways to be sensitive the environment. Recycling means finding ways to used products a second time. The motto of the recycling movement is "Reduce, Reuse, Recycle".The first step is to reduce garbage. In stores, a shopper has to buy products in blister packs, boxes and expensive plastic wrappings. A hamburger from a fast food restaurant comes in lots of packaging: usually paper, a box, and a bag. All that packaging is wasted resources. People should try to buy things that are wrapped simply, and to reuse cups and utensils. Another way to reduce waste is to buy high-quality products. When low quality appliances break, many customers throw them away and buy new ones - a loss of more resources and more energy. For example, if a customer buys a high-quality appliance that can be easily repaired, the manufacturer receives an important message. In the same way, if a customer chooses a product with less packaging, that customer sends an important message to the manufacturers. To reduce garbage, the throwaway must stop.The second step is to reuse. It is better to buy juices and soft drinks in returnable bottles. After customers empty the bottles, they return them to the store. The manufacturers of the drinks collect the bottles, wash them, and then fill them again. The energy that is necessary to make new bottles is saved. In some parts of the world, returning bottles for money is a common practice. In those places, the garbage dumps have relatively little glass and plastic from throwaway bottles.The third step is being environmentally sensitive is to recycle. Spent motor oil can be cleaned and used again. Aluminum cans are expensive to make. It takes the same amount of energy to make one aluminum can as it does to run a color TV set for three hours. When people collect and recycle aluminum (for new cans), they help save one of the world's precious resources.What best describe the process of reuse?
