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

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. A. infer  B. assume  C. bear  D. pertain  56.

A. precautions  B. resolutions  C. proceeds  D. measurements  60. A. comprised  B. derived  C. procured  D. provided    3     
 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.  4   
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        5    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    B. WRITTEN TEST   
I. CLOZE TEST (20 PTS): Read the texts below and complete each space with ONE  suitable word.  Passage A 
The British are widely considered to be a very polite nation, and in some respects this is true. An 
Italian journalist once commented that the British need no (1) ______ than four “thank yous” (2) ______ 
to buy a bus ticket. The first, from the bus conductor means, “I am here”. The second accompanies the 
handing (3) ______ of the money. The third, again from the conductor, means “(4) ______ is your 
ticket”, and then the passenger utters a final (5) ______ as he accepts the ticket. Such transactions in 
most other parts of the world are usually conducted in total silence. 
In sharp (6) ______ to this excessive politeness with strangers, the British are strangely lacking in 
ritual phrases for social interaction. The exhortation “Good appetite”, uttered in (7) ______ many other 
languages to fellow diners before a meal, does not (8) ______ in English. The nearest equivalent - Enjoy 
your dinner! - is said only by people who will not be partaking of the meal (9) ______ question. What's  6

celebrations such as birthdays, the Greeks routinely wish (10) ______ and sundry a “good week” or a  “good month”.  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. 
This fast growing trend of early retirement or redundancy risks creating a group of two million men 
who are (14) ______ little with their lives and whose sedentary lifestyle may jeopardise their well-being. 
Men aged 50-64 are (15) ______ two and three times as likely to die of a heart attack or stroke as (16)

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.
