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 economic expansion prompted by the Second World War triggered a spectacular population boom in the West. Of course, the region was no stranger to population booms. Throughout much of its history, western settlement had been characterized by spurts, rather than by a pattern of gradual and steady population growth, beginning with the gold and silver rushes of the 1850's and 1860's. The decade after the First World War - the 1920's - witnessed another major surge of people pouring into the West, particularly into urban areas. But the economic depression of the 1930's brought this expansion to a halt; some of the more sparsely settled parts of the region actually lost population as migrants sought work in more heavily industrialized areas. By 1941 when the United States entered the Second World War and began to mobilize, new job opportunities were created in the western part of the nation.          If the expansion of industries, such as shipbuilding and aircraft manufacturing, was most striking on the pacific coast, it also affected interior cities like Denver, Phoenix, and Salt Lake City. Equally dramatic were the effects of the establishment of aluminum plants in Oregon and Washington and the burgeoning steel industry in Utah and California.

As land had served as a magnet for western migrants in the late nineteenth century, so wartime mobilization set in motion another major expansion of population. Indeed, it could be said that the entire western United States became a giant boomtown during the Second World War. This was especially true of California. Of the more than eight million people who moved into the West in the decade after 1940, almost one-half went to the Pacific coast. In fact, between 1940 and 1950, California's population surged by more than three million people.The word “it” in paragraph 2 refers 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. Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very different types of flatfish and they have evolved in very separate ways. The skates and rays, relatives of the sharks have become flat in what might be called the obvious way. Their bodies have grown out sideways to form great “wings” They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely fish such as plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole vertically flattened bodies as swimming surfaces, which undulate through the water as they move. Therefore when * their ancestors migrated to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless - In evolution this problem was solved by the lower eye “moving” around the other side. We see this process of moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion, so that one eye for instance the left, moves over the top of the head upwards, an old Picasso - like vision. Incidentally, some species of 20 flatfish settle on the right side, others on the left, and others on either sideAccording to the passage, the ability of a bony flatfish to move its eyes around is:

Read the following passage and mark the letter A, B, C, D on your answer sheet to indicate the correct answer to each of the questions Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut downIn line 13, the phrase “this outlook” refers 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 questionsTelecommuting is some form of computer communication between employees’ homes and offices. For employees whose job involve sitting at a terminal or word processor entering data or typing reports, the location of the computer is of no consequence. If the machine can communicate over telephone lines, when the work is completed, employees can dial the office computer and transmit the material to their employers. A recent survey in USA Today estimates that there are approximately 8,7 million telecommuters. But although the numbers are rising annually, the trend does not appear to be as significant as predicted when Business Week published “The Portable Executive” as its cover story a few years ago. Why hasn’t telecommuting become more popular?Clearly, change simply takes time. But in addition, there has been active resistance on the part of many managers. These executives claim that supervising the telecommuters in a large work force scattered across the country would be too difficult, or, at least, systems for managing them are not yet developed, thereby complicating the manager’s responsibilities.It is also true that employees who are given the option of telecommuting are reluctant to accept the opportunity. Most people feel that they need regular interaction with a group, and many are concerned that they will not have the same consideration for advancement if they are not more visible in the office setting. Some people feel that even when a space in their homes is set aside as a work area, they never really get away from the office.The word “reluctant” in the third paragraph can best be replaced by

But the economic depression of the 1930's brought this expansion to a halt; some of the more sparsely settled parts of the region actually lost population as migrants sought work in more heavily industrialized areas. By 1941 when the United States entered the Second World War and began to mobilize, new job opportunities were created in the western part of the nation.          If the expansion of industries, such as shipbuilding and aircraft manufacturing, was most striking on the pacific coast, it also affected interior cities like Denver, Phoenix, and Salt Lake City. Equally dramatic were the effects of the establishment of aluminum plants in Oregon and Washington and the burgeoning steel industry in Utah and California. The flow of people into these areas provided an enormous impetus to the expansion of the service industries - banks, health care services and schools. Although strained to the limit by the influx of newcomers, western communities welcomed the vast reservoir of new job opportunities. At the same time, the unprecedented expansion of government installations in the West, such as military bases, created thousands of new civilian openings. As land had served as a magnet for western migrants in the late nineteenth century, so wartime mobilization set in motion another major expansion of population. Indeed, it could be said that the entire western United States became a giant boomtown during the Second World War. This was especially true of California. Of the more than eight million people who moved into the West in the decade after 1940, almost one-half went to the Pacific coast. In fact, between 1940 and 1950, California's population surged by more than three million people.What is the main point of the passage?

ĐỀ 10

Read the following passage and mark the letter A, B, C, D on your answer sheet to indicate the correct answer to each of the questions Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut downHow does the author describe the attitude of the population in regard to nuclear power as fuel in the early to the mid 1970s?
