Read the following passage and mark the letter A, B, C or D to indicate the correct answer.The Nobel Peace Prize is awarded annually and the first woman to win this prize was Baroness Bertha Felicie Sophie von Suttner in 1905. In fact, her work inspired the creation of the Prize. The first American woman to win this prize was Jane Addams, in 1931. However, Addams is best known as the founder of Hull House.Jane Addams was born in 1860, into a wealthy family. She was one of a small number of women in her generation to graduate from college. Her commitment to improving the lives of those around her led her to work for social reform and world peace. In the 1880s Jane Addams traveled to Europe. While she was in London, she visited a ‘settlement house’ called Toynbee Hall. Inspired by Toynbee Hall, Addams and her friend, Ellen Gates Starr, opened Hull House in a neighborhood of slums in Chicago in 1899. Hull House provided a day care center for children of working mothers, a community kitchen, and visiting nurses. Addams and her staff gave classes in English literacy, art, and other subjects. Hull House also became a meeting place for clubs and labor unions. Most of the people who worked with Addams in Hull House were well educated, middle-class women. Hull House gave them an opportunity to use their education and it provided a training ground for careers in social work.Before World War I, Addams was probably the most beloved woman in America. In a newspaper poll that asked, “Who among our contemporaries are of the most value to the community?”, Jane Addams was rated second, after Thomas Edison. When she opposed America’s involvement in World War I, however, newspaper editors called her a traitor and a fool, but she never changed her mind. Jane Addams was a strong champion of several other causes. Until 1920, American women could not vote. Addams joined in the movement for women’s suffrage and was a vice president of the National American Woman Suffrage Association. She was a founding member of the National Association for the Advancement of Colored People (NAACP), and was president of the Women’s International League for Peace and Freedom. . Her reputation was gradually restored during the last years of her life. She died of cancer in 1935. The word “restored” in line 29 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 following questions          The dream of a canal across the Isthmus of Suez had existed since the time 4,000 years ago when the pharaohs built Egypt's first canal. (It linked the Nile River with the Great Bitter Lake, which then opened onto the Gulf of Suez.) This canal, however, was filled in, and for centuries trade with the Far East was carried overland across Asia. Eventually ships began to sail around the southern tip of Africa to reach the Mediterranean Sea from the Red Sea.          Then in 1858 a French engineer, Ferdinand de Lesseps, acquired the rights from his friend, Said Pasha, viceroy of Egypt, to organize a company and build a canal. On November 17, 1869, the Suez Canal was opened with great ceremony at the northern terminus, Port Said, which was named for Said Pasha. The 12,400-mile (19,950-kilometer) voyage from London around South Africa to Bombay, India, was shortened to 7,250 miles (11,670 kilometers).The Suez Canal is 101 miles (163 kilometers) long, or about twice the length of the Panama Canal. The Suez was easier to construct because it crosses flat, sea-level terrain and requires no locks. About 24 miles (39 kilometers) of the canal are channels dredged through lakes. Most of the banks of the other 77 miles (123 kilometers) are reinforced with stone, cement, or steel to help prevent erosion.The main channels of the canal are dredged to a depth of about 66 feet (20 meters), and the navigational width between buoys is set at 596 feet (180 meters). Double channels, where ships traveling in opposite directions can pass without stopping, have been constructed at four locations and cover a little more than 41 miles (67 kilometers). The largest ships allowed to pass through the canal may have a beam of up to 210 feet (64 meters) wide and a draught (belowwater depth) of up to 53 feet (16 meters).Ships move through the canal under their own power, but large ships must be accompanied by a tugboat. The trip takes roughly 12 to 18 hours. To prevent accidents, vessels must travel in convoys at fixed speeds, fixed intervals and fixed distances between passing ships. Convoys going in opposite directions are usually timed so they will pass each other in the Great Bitter Lake where there is a long double channel.Each day two convoys from south to north and one convoy from north to south sail through the canal, with a maximum total of 80 vessels a day. Yearly traffic numbers about 20,000 ships carrying between 300 million and 400 million net tons. Tankers and cargo ships account for nearly all canal traffic, but occasionally passenger liners and warships use the waterway. Northbound cargo is chiefly oil from the Persian Gulf headed for Western Europe. Southbound cargo consists mainly of manufactured goods and grain from Europe and North America destined for the Far East and southern Asia.Which of the following is TRUE of the passage?

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 53 to 62.History books recorded that the first film with sound was The Jazz Singer in 1927. But sound films, or talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in 1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound that was reproduced at exactly at the same time as the pictures – called “synchronized sound” – began soon after the very first films were shown. With synchronized sound, characters on the movie screen could sing and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and dialogue, was used as a sound system. The biggest disadvantage was that the sound and pictures could become unsynchronized if, for example, the gramophone needle jumped or if the speed of the projector changed. This system was only effective for a single song or dialogue sequence.In the “sound-on-film” system, sound was recorded as a series of marks on celluloid which could be read by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing synchronization. Short feature films were produced in this way as early as 1922. This system eventually brought us “talking pictures”.Short feature films produced as early as 1922 _________.

This system was only effective for a single song or dialogue sequence.In the “sound-on-film” system, sound was recorded as a series of marks on celluloid which could be read by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing synchronization. Short feature films were produced in this way as early as 1922. This system eventually brought us “talking pictures”.According to the passage, the phrase “these signals” refers to _________.

In fact, her work inspired the creation of the Prize. The first American woman to win this prize was Jane Addams, in 1931. However, Addams is best known as the founder of Hull House.Jane Addams was born in 1860, into a wealthy family. She was one of a small number of women in her generation to graduate from college. Her commitment to improving the lives of those around her led her to work for social reform and world peace. In the 1880s Jane Addams traveled to Europe. While she was in London, she visited a ‘settlement house’ called Toynbee Hall. Inspired by Toynbee Hall, Addams and her friend, Ellen Gates Starr, opened Hull House in a neighborhood of slums in Chicago in 1899. Hull House provided a day care center for children of working mothers, a community kitchen, and visiting nurses. Addams and her staff gave classes in English literacy, art, and other subjects. Hull House also became a meeting place for clubs and labor unions. Most of the people who worked with Addams in Hull House were well educated, middle-class women. Hull House gave them an opportunity to use their education and it provided a training ground for careers in social work.Before World War I, Addams was probably the most beloved woman in America. In a newspaper poll that asked, “Who among our contemporaries are of the most value to the community?”, Jane Addams was rated second, after Thomas Edison. When she opposed America’s involvement in World War I, however, newspaper editors called her a traitor and a fool, but she never changed her mind. Jane Addams was a strong champion of several other causes. Until 1920, American women could not vote.

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 following questions          The dream of a canal across the Isthmus of Suez had existed since the time 4,000 years ago when the pharaohs built Egypt's first canal. (It linked the Nile River with the Great Bitter Lake, which then opened onto the Gulf of Suez.) This canal, however, was filled in, and for centuries trade with the Far East was carried overland across Asia. Eventually ships began to sail around the southern tip of Africa to reach the Mediterranean Sea from the Red Sea.          Then in 1858 a French engineer, Ferdinand de Lesseps, acquired the rights from his friend, Said Pasha, viceroy of Egypt, to organize a company and build a canal. On November 17, 1869, the Suez Canal was opened with great ceremony at the northern terminus, Port Said, which was named for Said Pasha. The 12,400-mile (19,950-kilometer) voyage from London around South Africa to Bombay, India, was shortened to 7,250 miles (11,670 kilometers).The Suez Canal is 101 miles (163 kilometers) long, or about twice the length of the Panama Canal. The Suez was easier to construct because it crosses flat, sea-level terrain and requires no locks. About 24 miles (39 kilometers) of the canal are channels dredged through lakes. Most of the banks of the other 77 miles (123 kilometers) are reinforced with stone, cement, or steel to help prevent erosion.The main channels of the canal are dredged to a depth of about 66 feet (20 meters), and the navigational width between buoys is set at 596 feet (180 meters). Double channels, where ships traveling in opposite directions can pass without stopping, have been constructed at four locations and cover a little more than 41 miles (67 kilometers). The largest ships allowed to pass through the canal may have a beam of up to 210 feet (64 meters) wide and a draught (belowwater depth) of up to 53 feet (16 meters).Ships move through the canal under their own power, but large ships must be accompanied by a tugboat. The trip takes roughly 12 to 18 hours. To prevent accidents, vessels must travel in convoys at fixed speeds, fixed intervals and fixed distances between passing ships. Convoys going in opposite directions are usually timed so they will pass each other in the Great Bitter Lake where there is a long double channel.Each day two convoys from south to north and one convoy from north to south sail through the canal, with a maximum total of 80 vessels a day. Yearly traffic numbers about 20,000 ships carrying between 300 million and 400 million net tons. Tankers and cargo ships account for nearly all canal traffic, but occasionally passenger liners and warships use the waterway. Northbound cargo is chiefly oil from the Persian Gulf headed for Western Europe. Southbound cargo consists mainly of manufactured goods and grain from Europe and North America destined for the Far East and southern Asia.After the digging of the Suez Canal, the whole voyage from London to India was _______.

But sound films, or talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in 1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound that was reproduced at exactly at the same time as the pictures – called “synchronized sound” – began soon after the very first films were shown. With synchronized sound, characters on the movie screen could sing and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and dialogue, was used as a sound system.

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 43 to 50.        An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous changes. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened.

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 43 to 50.        An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous changes. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened.

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 53 to 62.History books recorded that the first film with sound was The Jazz Singer in 1927. But sound films, or talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in 1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound that was reproduced at exactly at the same time as the pictures – called “synchronized sound” – began soon after the very first films were shown. With synchronized sound, characters on the movie screen could sing and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and dialogue, was used as a sound system. The biggest disadvantage was that the sound and pictures could become unsynchronized if, for example, the gramophone needle jumped or if the speed of the projector changed. This system was only effective for a single song or dialogue sequence.In the “sound-on-film” system, sound was recorded as a series of marks on celluloid which could be read by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing synchronization. Short feature films were produced in this way as early as 1922. This system eventually brought us “talking pictures”.The word “screenings” in is closest in meaning to _________.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer.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 scene. 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 give in displaying individual styles. Crivelli wanted to show depth in his picture and he used a simple single-point perspective. Cezanne always talked 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 paintings 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. It can be inferred from the passage that Renaissance artists

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 following questions          The dream of a canal across the Isthmus of Suez had existed since the time 4,000 years ago when the pharaohs built Egypt's first canal. (It linked the Nile River with the Great Bitter Lake, which then opened onto the Gulf of Suez.) This canal, however, was filled in, and for centuries trade with the Far East was carried overland across Asia. Eventually ships began to sail around the southern tip of Africa to reach the Mediterranean Sea from the Red Sea.          Then in 1858 a French engineer, Ferdinand de Lesseps, acquired the rights from his friend, Said Pasha, viceroy of Egypt, to organize a company and build a canal. On November 17, 1869, the Suez Canal was opened with great ceremony at the northern terminus, Port Said, which was named for Said Pasha. The 12,400-mile (19,950-kilometer) voyage from London around South Africa to Bombay, India, was shortened to 7,250 miles (11,670 kilometers).The Suez Canal is 101 miles (163 kilometers) long, or about twice the length of the Panama Canal. The Suez was easier to construct because it crosses flat, sea-level terrain and requires no locks. About 24 miles (39 kilometers) of the canal are channels dredged through lakes. Most of the banks of the other 77 miles (123 kilometers) are reinforced with stone, cement, or steel to help prevent erosion.The main channels of the canal are dredged to a depth of about 66 feet (20 meters), and the navigational width between buoys is set at 596 feet (180 meters). Double channels, where ships traveling in opposite directions can pass without stopping, have been constructed at four locations and cover a little more than 41 miles (67 kilometers). The largest ships allowed to pass through the canal may have a beam of up to 210 feet (64 meters) wide and a draught (belowwater depth) of up to 53 feet (16 meters).Ships move through the canal under their own power, but large ships must be accompanied by a tugboat. The trip takes roughly 12 to 18 hours. To prevent accidents, vessels must travel in convoys at fixed speeds, fixed intervals and fixed distances between passing ships. Convoys going in opposite directions are usually timed so they will pass each other in the Great Bitter Lake where there is a long double channel.Each day two convoys from south to north and one convoy from north to south sail through the canal, with a maximum total of 80 vessels a day. Yearly traffic numbers about 20,000 ships carrying between 300 million and 400 million net tons. Tankers and cargo ships account for nearly all canal traffic, but occasionally passenger liners and warships use the waterway. Northbound cargo is chiefly oil from the Persian Gulf headed for Western Europe. Southbound cargo consists mainly of manufactured goods and grain from Europe and North America destined for the Far East and southern Asia.People dreamt of a canal like Suez Canal now ________.
