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 35 to 42.        As the twentieth century began, the importance of formal education in the United States increased. The frontier had mostly disappeared and by 1910 most Americans lived in towns and cities. Industrialization and the bureaucratization of economic life combined with a new emphasis upon credentials and expertise to make schooling increasingly important for economic and social mobility. Increasingly, too, schools were viewed as the most important means of integrating immigrants into American society.        The arrival of a great wave of southern and eastern European immigrants at the turn of the century coincided with and contributed to an enormous expansion of formal schooling. By 1920 schooling to age fourteen or beyond was compulsory in most states, and the school year was greatly lengthened. Kindergartens, vacation schools, extracurricular activities, and vocational education and counseling extended the influence of public schools over the lives of students, many of whom in the larger industrial cities were the children of immigrants. Classes for adult immigrants were sponsored by public schools, corporations, unions, churches, settlement houses, and other agencies.        Reformers early in the twentieth century suggested that education programs should suit the needs of specific populations. Immigrant women were once such population. Schools tried to educate young women so they could occupy productive places in the urban industrial economy, and one place many educators considered appropriate for women was the home.        Although looking after the house and family was familiar to immigrant women, American education gave homemaking a new definition. In preindustrial economies, homemaking had meant the production as well as the consumption of goods, and it commonly included income-producing activities both inside and outside the home, in the highly industrialized early-twentieth-century United States, however, overproduction rather than scarcity was becoming a problem. Thus, the ideal American homemaker was viewed as a consumer rather than a producer. Schools trained women to be consumer homemakers cooking, shopping, decorating, and caring for children "efficiently" in their own homes, or if economic necessity demanded, as employees in the homes of others. Subsequent reforms have made these notions seem quite out-of-date.All of the following statements are true EXCEPT _____ .

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected. The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health. On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about. As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.The phrase "negative publicity" in the passage most likely means ____________.

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 30 to 34.        A tropical cyclone is a violent low pressure storm that usually occurs over warm oceans of over 80°F or 27°C. It winds counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as it is described for the term, cyclone itself. This powerful storm is fueled by the heat energy that is released when water vapor condenses at high altitudes, the heat ultimately derived from the Sun.        The center of a tropical cyclone, called the eye, is relatively calm and warm. This eye, which is roughly 20 to 30 miles wide, is clear, mainly because of subsiding air within it. The ring of clouds around the eye is the eyewall, where clouds reach highest and precipitation is heaviest. The strong wind, gusting up to 360 kilometers per hour, occurs when a tropical cyclone’s eyewall passes over land.        There are various names for a tropical cyclone depending on its location and strength. In Asia, a tropical cyclone is named according to its strength. The strongest is a typhoon; its winds move at more than 117 kilometers per hour. In India, it is called a cyclone. Over the North Atlantic and in the South Pacific, they call it a hurricane.        On average, there are about 100 tropical cyclones worldwide each year. A tropical cyclone peaks in late summer when the difference between temperature in the air and sea surface is the greatest. However, it has its own seasonal patterns. May is the least active month, while September is the most active.        The destruction associated with a tropical cyclone results not only from the force of the wind, but also from the storm surge and the waves it generates. It is born and sustained over large bodies of warm water, and loses its strength over inland regions that are comparatively safe from receiving strong winds. Although the tract of a tropical cyclone is very erratic, the Weather Service can still issue timely warnings to the public if a tropical cyclone is approaching densely populated areas. If people ever experience a cyclone, they would know how strong it could be.The word “erratic” in paragraph 5 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 30 to 34.        A tropical cyclone is a violent low pressure storm that usually occurs over warm oceans of over 80°F or 27°C. It winds counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as it is described for the term, cyclone itself. This powerful storm is fueled by the heat energy that is released when water vapor condenses at high altitudes, the heat ultimately derived from the Sun.        The center of a tropical cyclone, called the eye, is relatively calm and warm. This eye, which is roughly 20 to 30 miles wide, is clear, mainly because of subsiding air within it. The ring of clouds around the eye is the eyewall, where clouds reach highest and precipitation is heaviest. The strong wind, gusting up to 360 kilometers per hour, occurs when a tropical cyclone’s eyewall passes over land.        There are various names for a tropical cyclone depending on its location and strength. In Asia, a tropical cyclone is named according to its strength. The strongest is a typhoon; its winds move at more than 117 kilometers per hour. In India, it is called a cyclone. Over the North Atlantic and in the South Pacific, they call it a hurricane.        On average, there are about 100 tropical cyclones worldwide each year. A tropical cyclone peaks in late summer when the difference between temperature in the air and sea surface is the greatest. However, it has its own seasonal patterns. May is the least active month, while September is the most active.        The destruction associated with a tropical cyclone results not only from the force of the wind, but also from the storm surge and the waves it generates. It is born and sustained over large bodies of warm water, and loses its strength over inland regions that are comparatively safe from receiving strong winds. Although the tract of a tropical cyclone is very erratic, the Weather Service can still issue timely warnings to the public if a tropical cyclone is approaching densely populated areas. If people ever experience a cyclone, they would know how strong it could be.The word “it” in paragraph 5 refers to _____.

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected. The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health. On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about. As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.The word "potentially" in the passage most closely means ____________.

Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a by-product of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it. Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes accustomed. Loud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased. Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America's number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each otherQuestion:It can be inferred from the passage that the eye ___.

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 55 to 64An 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 change. 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. In the future, even water vapor might be considered an air pollutant under certain conditions.Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppmWhich of the following is best supported by the passage?

A tropical cyclone peaks in late summer when the difference between temperature in the air and sea surface is the greatest. However, it has its own seasonal patterns. May is the least active month, while September is the most active.        The destruction associated with a tropical cyclone results not only from the force of the wind, but also from the storm surge and the waves it generates. It is born and sustained over large bodies of warm water, and loses its strength over inland regions that are comparatively safe from receiving strong winds. Although the tract of a tropical cyclone is very erratic, the Weather Service can still issue timely warnings to the public if a tropical cyclone is approaching densely populated areas. If people ever experience a cyclone, they would know how strong it could be.What is the main idea of the passage?
