Read the following passage on transport, 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.     (1) Increasing numbers of parents in the U.S. are choosing to teach their children at home. In fact, the U.S. Department of Education has estimated that in 1999, about 850,000 children were being homeschooled. Some educational experts say that the real number is double this estimate, and the ranks of homeschooled children seem to be growing at the average rate of about eleven percent every year.     (2) At one time, there was a theory accounting for homeschooling: it was traditionally used for students who could not attend school because of behavioral or learning difficulties. Today, however, more parents are taking on the responsibility of educating their own children at home due to their dissatisfaction with the educational system. Many parents are unhappy about class size, as well as problems inside the classroom. Teacher shortages and lack of funding mean that, in many schools, one teacher is responsible for thirty or forty students. The children are, therefore, deprived of the attention they need. Escalating classroom violence has also motivated some parents to remove their children from school.     (3) Although there have been a lot of arguments for and against it, homeschooling in the U.S. has become a multi-million dollar industry, and it is growing bigger and bigger. There are now plenty of websites, support groups, and conventions that help parents protect their rights and enable them to learn more about educating their children. Though once it was the only choice for troubled children, homeschooling today is an accepted alternative to an educational system that many believe is failing. The attitude of the author towards homeschooling can be best described as _____.

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.Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements felt no more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun.Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide is correspondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the monthWhat is the cause of spring tides?

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 36 to 42.     (1) Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.     (2) Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.    (3) All the major organs of the body show signs of aging. The brain, for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.     (4) One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack.     (5) Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fibers can never be replaced once they wear out.     (6) Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years. According to the passage, which of the following is NOT true?

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.Most journeys in Britain and the US are made by road. Some of these are made on public transport but most are by private car. In Britain many people rely on their cars for daily local activities, e.g. getting to work, doing the shopping, and visiting friends. People living in urban areas may use buses, trains or, in London, the Underground, to get to city centres, mainly because traffic is often heavy and it is difficult to find anywhere to park a car. Some places in the country may have a bus only two or three times a week so people living there have no choice but to rely on their cars.In the US large cities have good public transportation systems. The El railroad in Chicago and the underground systems of New York, Boston, San Francisco and Washington, DC are heavily used. Elsewhere, most Americans prefer to use their cars. Families often have two cars and, outside major cities, have to drive fairly long distances to schools, offices, shops, banks, etc. Many college and even high-school students have their own cars.Long-distance travel in Britain is also mainly by road, though railways link most towns and cities. Most places are linked by motorways or other fast roads and many people prefer to drive at their own convenience rather than use a train, even though they may get stuck in a traffic jam. Long-distance coach/bus services are usually a cheaper alternative to trains, but they take longer and may be less comfortable. Some long-distance travel, especially that undertaken for business reasons, may be by air. There are regular flights between regional airports, as well as to and from London. A lot of freight is also distributed by road, though heavier items and raw materials often go by rail.In the US much long-distance travel is by air. America has two main long-distance bus companies, Greyhound and Trailways. Amtrak, the national network, provides rail services for passengers. Private railway companies such as Union Pacific now carry only freight, though in fact over 70% of freight goes by road.The main problems associated with road transport in both Britain and the US are traffic congestion and pollution. It is predicted that the number of cars on British roads will increase by a third within a few years, making both these problems worse. The British government would like more people to use public transport, but so far they have had little success in persuading people to give up their cars or to share rides with neighbours. Most people say that public transport is simply not good enough. Americans too have resisted government requests to share cars because it is less convenient and restricts their freedom. Petrol/gasoline is relatively cheap in the US and outside the major cities public transport is bad, so they see no reason to use their cars less.(Extracted from Oxford Guide to British and American Culture, Oxford University Press, 2000)The word “they” in the last sentence of the passage can best be replaced by ______.

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.Most journeys in Britain and the US are made by road. Some of these are made on public transport but most are by private car. In Britain many people rely on their cars for daily local activities, e.g. getting to work, doing the shopping, and visiting friends. People living in urban areas may use buses, trains or, in London, the Underground, to get to city centres, mainly because traffic is often heavy and it is difficult to find anywhere to park a car. Some places in the country may have a bus only two or three times a week so people living there have no choice but to rely on their cars.In the US large cities have good public transportation systems. The El railroad in Chicago and the underground systems of New York, Boston, San Francisco and Washington, DC are heavily used. Elsewhere, most Americans prefer to use their cars. Families often have two cars and, outside major cities, have to drive fairly long distances to schools, offices, shops, banks, etc. Many college and even high-school students have their own cars.Long-distance travel in Britain is also mainly by road, though railways link most towns and cities. Most places are linked by motorways or other fast roads and many people prefer to drive at their own convenience rather than use a train, even though they may get stuck in a traffic jam. Long-distance coach/bus services are usually a cheaper alternative to trains, but they take longer and may be less comfortable. Some long-distance travel, especially that undertaken for business reasons, may be by air. There are regular flights between regional airports, as well as to and from London. A lot of freight is also distributed by road, though heavier items and raw materials often go by rail.In the US much long-distance travel is by air. America has two main long-distance bus companies, Greyhound and Trailways. Amtrak, the national network, provides rail services for passengers. Private railway companies such as Union Pacific now carry only freight, though in fact over 70% of freight goes by road.The main problems associated with road transport in both Britain and the US are traffic congestion and pollution. It is predicted that the number of cars on British roads will increase by a third within a few years, making both these problems worse. The British government would like more people to use public transport, but so far they have had little success in persuading people to give up their cars or to share rides with neighbours. Most people say that public transport is simply not good enough. Americans too have resisted government requests to share cars because it is less convenient and restricts their freedom. Petrol/gasoline is relatively cheap in the US and outside the major cities public transport is bad, so they see no reason to use their cars less.(Extracted from Oxford Guide to British and American Culture, Oxford University Press, 2000)It is stated in the passage that the major problems of road transport in Britain and the US are ______.

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.Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements felt no more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun.Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide is correspondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the month.What is the main point of the first paragraph?

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 36 to 42.     (1) Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.     (2) Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.     (3) All the major organs of the body show signs of aging. The brain, for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.     (4) One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack.     (5) Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fibers can never be replaced once they wear out.     (6) Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years. The word “brittle” as used in the second paragraph means _____.
