Business was bad. Sales were non-existent. I was (41) ______ at the bank. I'd (42) ______ up huge  debts and the man who sold me the shop was threatening to (43) ______ me because I hadn't paid him.  I had expected (44) ______ troubles when I took over the shop – all new businesses have problems in  the beginning – but in the eleven months I had been open I had never had a customer. I'd tried  everything to (45) ______ up business – ads in the local newspaper, mid-season sales, sponsoring the  local football team – but nothing I'd tried had worked. I was at my (46) ______ end. A friend suggested I  seek professional advice. He reassured me that his friend, Mr. Stott, would help me (47) ______ the  problem of disappointing sales. So there I was in the city, sitting across from Mr. Stott, a management  consultant. "Now you live here in Willonga, a desert town, and you bought the local bakery, but you didn't  keep it on as a bakery," he said.

Passage B 

Those who (51) ______ for a vegetarian diet must usually weigh up a variety of aspects concerning  the nutritional (52) ______ of vegetables and the adequacy of vegetarian meals in terms of the number of  nutrients provided to the body. Vegetarianism is not a new concept, rather an ancient custom which  evolved in the Far East cultures on ethical or religious grounds.  

In today's world, it has been undertaken by many followers who for a variety of reasons believe the  vegetarian diet more preferable to that containing meat. For example, there's the theory that animal meat  wasn't originally a component of the staple human diet as mankind evolved from foragers who later (53)  ______ a taste for flesh. Hence, our primeval ancestors are alleged to have had a substantial intake of  proteins and vitamins from natural vegetation rather than from the meat of hunted (54) ______. What’s  more, human teeth don’t (55) ______ much resemblance to those of animal carnivores, and neither is our  digestive system equivalent to the meat eaters' one. 

Apart from the enforced vegetarianism of underdeveloped communities where populations deprived of  animal protein (56) ______ the natural vegetation, there's a rising acceptance of the vegetarian diet  which (57) ______ to be regarded as an eccentricity. (58) ______ from animal food, be it for religious,  economic or humanitarian reasons, has been a quickly spreading custom as, surprisingly, the vegetarian  diet needn't be dull or deficient. Yet, it does involve taking good (59) ______ to supply the body with a  sufficient quantity of nutrients (60) ______ from corn, seeds and cereals.  

51. A. prefer B. opt C. select D. favour 52. A. profit B. rate C. value D. esteem 53. A. generated B. acquired C. instituted D. accustomed 54. A. load B. game C. toll D. beat 55.

V. READING COMPREHENSION (10 PTS): Read the texts below and choose the best answer  to each question. 

Passage A 

Recognized as having the largest “green roof” in the world, the new Ford Truck Assembly Plant in  Dearborn, Michigan, serves as a model for the 21st century. In this time of growing concern for  environmental issues from global warming to urban sprawl, the Ford plant shows it’s possible to reduce  these concerns by means of well-designed “green architecture.” 

Green roofs are, as the name implies, gardens that are placed on the roof of a building. These  roofs are composed of a waterproofing and root-repellant system designed to protect the underlying  building structure, a drainage system, a lightweight growing medium, and plants selected based on  characteristics such as drought tolerance. The gardens are designed to be self-sustaining, requiring little  upkeep except for occasional weeding or fertilization. 

In addition to supporting plant growth, the growing medium absorbs water. Experts cite the latter  as the single most important advantage of green roof technology, because the plants store rainwater and  return it to the atmosphere. It is predicted that the Ford Plant green roof will retain 447,000 gallons of  water per year, conserving 50 percent of the rain that falls on the roof each year. Less rainwater also  means less water that must pass through the city’s water sewage treatment facilities. 

What runoff there is has been filtered by the roof system. In addition, green roofs improve air  quality by filtering the air above them and encouraging the exchange of carbon dioxide and oxygen  through photosynthesis. Furthermore, they reduce the “heat island” effect in cities caused by the ever increasing amount of hard surfaces that absorb solar radiation. Finally, green roofs are aesthetically  appealing: they improve the appearance of barren urban and industrial sites. 

61. What is the main idea of this passage? 

A. Green roofs have a variety of environmental benefits. 

B. Green roofs can solve the problem of global warming. 

C. Green roofs need less maintenance than regular roofs. 

D. Green roofs are becoming more common on automotive plants. 

62. How often do roof gardens need to be planted? 

A. annually each spring B. when there is below-average rainfall C. every time it rains D. only once when created 

63. According to the passage, what is the most significant benefit of a green roof? A. It cools the building it is on. B. It retains rainwater. 

C. It supports plant life. D. It absorbs solar radiation. 

64. According to the passage, what is one way in which green roofs improve air quality? A. by promoting gas exchange B. by reflecting solar radiation 

C. by reducing air temperature D. by absorbing rainwater 

65. How do green roofs reduce the “heat island” effect? 

A. They retain a lot of rainwater. B. They capture less heat from the sun than traditional roofs. C. They reflect the sun’s heat. D. They increase the movement of air around the building. 

Passage B 

A map created by Martin Waldseemüller in 1507 and acquired by the United States Library of  Congress for ten million dollars is the most expensive one in its collection. Out of the one thousand copies  originally produced, it is the only copy of this twelve-panel woodcut map known to exist. Its rarity is a  significant factor contributing to its value. More important though, the map is special because it is the first  to depict the Pacific Ocean as a separate body of water, the first to depict a separate Western  Hemisphere, and the first to name that mass of land “America.” Waldseemüller christened the new lands  America in recognition of the explorer Amerigo Vespucci, who was the first to identify the New World of  North and South America as separate from Asia. 

More than naming the continents, the map challenges established beliefs. In the map, America is  represented as a long and slender piece of land. This appears to support the contention that the western  edge of the continents had not been explored until after 1507. However, the Americas only appear to be  narrow because the mapmaker used a technique that visually distorted the Earth’s surface on the edges  of the map. Moreover, using the longitude and latitude lines on the map to measure the width of the  continents, one comes up with measurements that match those done by satellite today. Thus, the western  edges of the Americas must have been reached earlier than presently thought.

Another mystery associated with the map is how Waldseemüller received the knowledge that he  needed to make the map. Waldseemüller was the canon, a high-ranking priest, of a monastery in the  mountains of France, and to this day scholars have no idea how discoveries an ocean away found their  way to this legendary mapmaker. 

66. What is remarkable about the measurement accuracy of the map? 

A. It accurately measures the width of the American continents. 

B. It distorts the width of the American continents. 

C. It is more accurate than the maps constructed today. 

D. There is nothing remarkable about the measurement accuracy. 

67. According to the passage, how did Waldseemüller get the information to accurately depict important  geographic discoveries in his map? 

A. He studied other maps. B. He was visited by Amerigo Vespucci at his monastery. C. No one knows. D. He corresponded with the explorers. 68. How does the map contribute to our understanding of world exploration? 

A. Amerigo Vespucci must have gone to Asia. 

B. The American continent used to be a different shape. 

C. It confirms that the Pacific was not explored until after 1507. 

D. Western America must have been explored before 1507. 

69. What do measurement calculations suggest about the mapmaker? 

A. He knew the size of the American continent. 

B. He would have done better with a satellite. 

C. He did not understand latitudes and longitudes. 

D. He thought the Americas were long and narrow. 

70. What is the main purpose of this passage? 

A. to explain the characteristics of a valuable map B. to show how to create an accurate map C. to discuss the significance of a particular map D. to discuss early explorers 

Passage C 

Lights on, lights off. Just the quick flick of a finger on a simple switch brightens or darkens the room. That power is the envy of geneticists. They long for similar ease in activating and de-activating genes  in cultured cells and transgenic animals. In recent years, these scientists have gained some measure of  control by using chemical compounds, including the antibiotic tetracycline, to govern genes in cells and  mice. 

The insect hormone ecdysone may provide the most effective gene switch yet, suggest investigators  from the Howard Hughes Medical Institute at the Salk Institute for Biological Studies in La Jolla, Calif., and  the University of California, San Diego. To support that contention, the group has made mammalian cells  and strains of mice with genes that are activated when ecdysone reaches them. 

With such a system, researchers should be able to examine the importance of the timing of gene  activity, particularly during an organism's development. Since the hormone has no adverse effect on  mammalian cells, ecdysone-based switches may ultimately provide a non-toxic way to control the  therapeutic genes inserted into humans. 

"It looks pretty promising. It seems to work as well as, if not better than, the tetracycline system,"  says Janet Rossant, a developmental biologist at the Mount Sinai Hospital in Toronto. 71. The opening paragraph provides an example of an application of ______.  

A. lights B. rooms C. electricity D. darkness 72. In recent years chemical compounds have helped scientists ______. 

A. to measure cultured cells B. to control gene activity to a certain extent C. to train mice D. to switch from genes to mice 

73. What have investigators managed to do with ecdysone? They've managed to______. A. affect the metabolism of special mice B. produce mammalian cells 

C. change the strains of ordinary mice D. activate ordinary mice 

74. What is an apparent advantage of ecdysone? 

A. It helps make mammalian cells. B. It does not harm mammalian cells. C. It is therapeutic. D. It will become non-toxic. 

75. According to the last paragraph, scientists are______. 

A. promising miracles B. clearly in favour of tetracycline instead C. looking for more promising alternatives D. optimistic about the potential of ecdysone


Passage D 

 Soybeans or cereal grains, such as wheat or corn, usually make people think of food. However, some  agricultural researchers are now working to make plastics out of such foods. The type of plastic products  researchers say can be made from plant material is limited only by the imagination.  Depending on how it’s formulated, the plastic can be either thin or thick, malleable or hard. Uses for  this new material could range from bottles to plastic-coated paper or car parts. For example, one  prototype plastic is made in a lab with a machine that mixes and heats the material and then squeezes it  out like giant spaghetti strands. Researchers speculate that anything now made from traditional  petroleum-based plastic could, in the future, be produced from compounds using plant material. They are  already developing some plastics using both grain starches and soybean proteins, the latter of which  seems to make stronger, more elastic products than grain starches do. Researchers hope that eventually  all the petroleum in plastics can be replaced with bio-based materials that are environmentally friendly.  These plastics would join other new bio-based products such as adhesives, fiberboard, diesel fuels, and  soy-oil based inks. Utilizing bio-based plastics would also create a new use for agricultural products, thus  benefiting farmers. 

 An important factor in the fate of bio-based plastics is their cost. For industry, cost is the principal  driving force that determines whether a new technology is adopted. If soy-based plastics can be made  more inexpensively than petroleum-based plastics, they are more likely to be considered a viable  alternative. 

 Though this is not the case yet, scientists hope that with time, bio-based plastics will become more  common. As a result, the cost will come down, as is the case with most new products such as computers  and cellular phones. 

76. What is the main purpose of this passage? 

A. to demonstrate the manufacturing process of bio-based plastics in a lab 

B. to explain how the cost of computers and cellular phones can be reduced 

C. to illustrate a new application of plant products 

D. to argue that bio-based products are more durable than petroleum-based products 77. Why does the author use the example of spaghetti strands? To illustrate ______. A. one form bio-based plastic can take 

B. possible uses of bio-based plastics 

C. how strong bio-based plastics can be 

D. how many different products can be made from bio-based plastics 

78. Why does the author mention computers and cellular phones?  

 As an example of products that______. 

A. are environmentally friendly B. can be made from bio-based materials C. created whole new industries D. became cheaper as they became more widely used 79. What are the advantages of bio-based plastics? 

A. They will reduce the costs of computers and cellular phones. 

B. They will replace petroleum as a fuel. 

C. They benefit the agricultural industry. 

D. They benefit the petroleum industry. 

80. According to the passage, what must happen to make industry adopt plant-based plastics?  They must become ______. 

A. more environmentally friendly B. more durable C. less malleable D. less expensive

Passage B 

Each generation of British men has worked for a shorter period than its predecessor. This state of  affairs may be considered desirable when it is a matter of choice, (11) ______ recently many people in  their fifties have had their working lives curtailed through redundancy. Nowadays almost a third of British  men over 50 but below pension age have (12) ______ paid work, and most have given up (13) ______ it.

DEFINITE TURN DETERIORATE AVOID ORDAIN  EXPECT CONCEIVE FOUND MUTATE PRECEDENT



Never in human history has a population so wilfully and deliberately defied nature as has the  present generation. How have we defied it? We have survived. Life (11) ______ at the start of the 19th  century was scarcely 40 years. Over the course of the last half-century, it has continued to increase  steadily by two years each decade. Our (12) ______ survival has produced a revolution in longevity which  is shaking the (13) ______ of societies around the world.

III. ERROR CORRECTION: (10PTS) The following passage contains 10 errors. Identify and  correct them. 

Located in the hypothalamus, the biological clock controls every circadian rhythm in the  body from what we eat, sleep and play to hormone levels, body temperature and  immune functions. The settings of our biological clock determine that we are by nature  early-rising “larks” or night “owls”. 

The convenience and instant access of today's society make it tempting to regard the 


biological clock as redundancy, but the costs of ignoring our internal timepiece can be  great. Despite several scientific studies showing that shift work is unhealthy and  disruptive to the biological clock, we are rapidly moving into a 24-hour society which  brings many of the same ills with it. 

10 

Studies have shown that although “owls” prefer late working shifts, their health has a  serious battering. They develop a range of symptoms including indigestion, ulcers,  fatigues and heart problems. Nor have the 'effects only physical: many subjects reported  feelings of depression and anxiety. A farther hazard of keeping unconventional hours is  an increased tendency to accident-proneness. In fact, many of the world's great disasters  15 

have taken place at the early hours of the morning because of the body's inability to  function efficiently at that time. Sleep researchers believe that the pursuer of a 24-hour  society can only lead to more man-made problems, accidents and fatal errors.
