questions 1-9
牐牐營n science, a theory is a reasonable explanation of observed evnets that are related.
a theory often involves an imaginary model that helps scientists picture the way an
obseved event could could be produced. a good example of this is found in the kinetic
molecular theory, in which gases are pictured as being made up of many small particles
that are in constant motion.
牐牐燗 useful theoty, in addition to explaining past observations, helps to predict events
that have not as yet been ovserved. after a theory has been publized, scientists design
experiments to test the theory. if observations confirm the scientists predictions, the
theory is supported. if observations do not confirm the predictions, the scientists must
search further. there may be a fault in the experiment, or the theory may have to be
revised or rejected.
牐牐燬cience involves imagination and creative thinking as well as collecting information
and performing experiments. facts by thenselves are not science. as the mathematician
jules henri poincare said: "science is built with facts just as a house is built with
bricks, but a collection of facts cannot be called science any more than a pile of bricks
can be called a house."
牐牐燤ost scientists start an investigation by finding out what other scientists have
learned avout a particular problem. after kmown facts have been gathered, the scientist
comes to the part of the investigation that requires considerable imagination. possible
solutions to the problem are formulated. these possible solutions are called hypotheses.
牐牐營n a way, any hypothesis is a leap into the unknown. it extents the scientist s
thinking beyond the known facts. the scientist plans experiments, performs calculations
and makes observations to test hypotheses. for without hypotheses, further investigation
lacks purpose and direction. wheb hypotheses are confirmed, they are incorporated
into theories.

question 10-20
牐牐燘y the mid-nineteenth century, the term "icebox" had entered the american
language, but ice was still only beginning to affect the diet of ordinary citizens in the
united states. the ice trade grew with the growth of cities. ice was used in hotels,
taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh
fish, and butter. after the civil war(1860-1865), as ice used to refrigerate freight
cars, it also came into household use. even before 1880, half the ice sold in new york,
philadelphia, and baltimore, and one-third oof that sold in boston and chicago, went to
families for their own use. this had become possible because a new household
convenience, th
e icebox, a precursor of the modern refrigerator, had been invented.
牐牐燤aking an efficient icebox was not as easy as we might now suppose. in the early
nineteenth century, the knowledge of the physics of heat, which was essential to a
science of refrigeration, was rudimentary. the commonsense notion that the best
icebox was one that prevented the ice from melting was of course mistaken, for it was
the melting of the ice that performed the cooling. nevertheless, early efforts to
economize ice included wrapping the ice in blankets, which kept the ice from doing its
job. not until near the end of the nineteenth century did inventors achieve the delicate
balance of insulation and circulation needed for an efficient icebox.
牐牐燘ut as early as 1803, an ingenious maryland farmer. thomas moore, had been on
the right track. he owned a farm about twenty miles outside the city of washington, for
which the village of georgetown was the market center. when he used an icebox of his
own design to transport his butter to market, he found that customers would pass up the
rapidly melting stuff in the tubs of his competitors to pay a premium price for his
butter, still fresh and hard in neat, one-pound bricks. one advantage of his icebox,
moore explained, was that farmers would no longer have to travel to market at night in
order to keep their produce cool.
10. what does the passage mainly discuss?
(a) the influence of ice on the diet
(b) the development of refrigeration

(a) many fish dealers also sold ice
(b) fish was shipped in refrigerated freight cars
(c) fish dealers were among the early commercial users of ice

question 21-30
牐牐燗side from perpetuating itself, the sole purpose of the american academy and
instiute of arts and letters is to "foster, assist and sustain an interest" in literature,
music, and art. this it does by enthusiastically handing out money. annual cash awards
are given to deserving artists in various categories of creativity: architecture, musical
composition, theater, novels, serious poetry, light verse,painting,sculpture. one award
subsidizes a promising american writer s visit to rome. there is even an award for a
very good work of fiction that falled commercially-once won by the young john
updike for the poorhouse fair and, more recently, by alice walker for in love and
trouble.
牐牐燭he awards and prizes total about $750,000 a year, but most of them range in size
from $5,000 to $12,500, a welcome sum to many young practitioners whose work may
not bring in that much in a year. one of the advantages of the awards is that
many go to the struggling artists, rather than to those who are already successful.
members of the academy and institute are not eligible for any cash prizes
. another
advantage is that, unlike the national endowment for the arts or similar institutions
throughout the world, there is no government money involved.
牐牐燗wards are made by committee. each of the three departments--literature
(120 members), art(83), music(47)--has a committee dealing with its own field.
committee membership rotates every year, so that new voices and opinions are
constantly heard.
牐牐燭he most financially rewarding of all the academy-institute awards are the mildred
and harold strauss livings. harold strauss, a devoted editor at alfred a. knopf, the
new york publishing house, and mildred strauss, his wife, were wealthy any childless.
they left the academy-institute a unique bequest: for five consecutive years, two
distinguished (and financially needy) writers would receive enough money so they
could devote themselves entirely to "prose literature" (no plays, no poetry, and no
paying job that might distract). in 1983, the first strauss livings of $35,000 a year
went to short-story writer raymond carver and novelist-essayist cynthia ozick. by
1988, the fund had grown enough so that two winners, novelists diane johnson and
robert stone, each got $50,000 a year for five years.
21. what does the passage mainly discuss?
(a) award-winning works of literature
(b) an organization that supports the arts

(d) individual patrons of the arts
22. the word "sole" in line 1 is closest in meaning to
(a) only
(b) honorable
(c) common
(d) official
23. the word "subsidizes" in line 6 is closest in meaning to
(a) assures
(b) finances
(c) schedules
(d) publishes
24. which of the following can be inferred about alice walker s book in love and trouble?
(a) it sold more copies than the poorhouse fair.
(b) it described the author s visit to rome.
(c) it was a commercial success.

questions 31-41
牐牐 archaeological records-paintings, drawings and carvings of humans engaged in
activities involving the use of hands-indicate that humans have been predominantly
right-handed for more than 5,000 years. in ancient egyptian artwork, for example, the
right hand is depicted as the dominant one in about 90 percent of the examples. fracture
or wear patterns on tools also indicate that a majority of ancient people were right-handed.
牐牐燙ro-magnon cave paintings some 27,000 years old commonly show outlines of human
hands made by placing one hand against the cave wall and applying paint with the
other. children today make similar outlines of their hands with crayons on paper. with
few exceptions, left hands of cro-magnans are displayed on cave walls, indicating that
the paintings were usually done by right-handers.
牐牐燗nthropological evidence pushes the record of handedness in early human ancestors
back to at least 1.4 million years ago. one important line of evidence comes from
flaking patterns of stone cores used in toolmaking: implements flaked with a
clockwise motion (indicating a right-handed toolmaker) can be distinguished from
those flaked with a counter-clockwise rotation (indicating a left-handed toolmaker).
牐牐燛ven scratches found on fossil human teeth offer clues. ancient humans are thought
to have cut meat into strips by holding it between their teeth and slicing it with stone
knives, as do the present-day inuit. occasionally the knives slip and leave scratches on
the users teeth. scratches made with a left-to-right stroke direction (by right-handers)
are more common than scratches in the opposite direction (made by left-handers).
牐牐燬till other evidence comes from cranial morphology: scientists think that physical
differences
between the right and left sides of the interior of the skull indicate subtle
physical differences between the two sides of the brain. the variation between the
hemispheres corresponds to which side of the body is used to perform specific
activities. such studies, as well as studies of tool use, indicate that right- or left-sided
dominance is not exclusive to modern homo sapiens. population of neanderthals,
such as homo erectus and homo habilis, seem to have been predominantly
right-handed, as we are.
31.what is the main idea of the passage?
(a) human ancestors became predominantly right-handed when they began to use tools.
(b) it is difficult to interpret the significance of anthropological evidence concerning tool use.
(c) humans and their ancestors have been predominantly right-handed for over a million years.
(d) human ancestors were more skilled at using both hands than modern humans.
32.the word "other" in line 8 refers to
(a) outline
(b) hand
(c) wall
(d) paint
33.what does the author say about cro-magnon paintings of hands?
(a) some are not very old.
(b) it is unusual to see such paintings.
(c) many were made by children.
(d) the artists were mostly right-handed.
34.the word "implements" in line 13 is closest in meaning to
(a) tools
(b) designs
(c) examples
(d) pieces
35.when compared with implements "flaked with a counter-clockwise rotation" (line 15), it can be inferred that "implements flaked with a clock-wise motion" (line13-14) are
(a) more common
(b) larger
(c) more sophisticated
(d) older
36 the word "clues" in line 16 is closest in meaning to
(a) solutions
(b) details
(c) damage
(d) information
37 the fact that the inuit cut meat by holding it between their teeth is significant because
(a) the relationship between handedness and scratches on fossil human teeth can be verified
(b) it emphasizes the differences between contemporary humans and their ancestors
(c) the scratch patterns produced by stone knives vary significantly from patterns produced by modern knives
(d) it demonstrates that ancient humans were not skilled at using tools
38 the word "hemispheres" in line 24 is closest in meaning to
(a) differences
(b) sides
(c) activities
(d) studies
39 why does the author mention homo erectus and home habilis in line 27?
(a) to contrast them with modern humans
(b) to explain when human ancestors began to make tools
(c) to show that early humans were also predominantly right handed
(d) to prove that the population of neanderthals was very large
40 all of the follows are mentioned as types of evidence concerning handedness except
(a) ancient artwork
(b) asymmetrical skulls
(c) studies of tool use
(d) fossilized hand bones
41 which of the following conclusions is suggested by the evidence from cranial morphology(line 21)?
(a) differences in the hemispheres of the brain probably came about relatively recently.
(b) there may be a link between handedness and differences in the brain s hemispheres
(c) left-handedness was somewhat more common among neanderthals
(d) ariation between the brain hemispheres was not evident in the skill of home erectus and home habilis
questions 42-50
牐牐燩lants are subject to attack and infection by a remarkable variety of symbiotic
species and have evolved a diverse array of mechanisms designed to frustrate the
potential colonists. these can be divided into preformed or passive defense mechanisms
and inducible or active systems. passive plant defense comprises physical and chemical
barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable
or toxic to the invader. the external surfaces of plants, in addition to being covered by
an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which
either prevent feetling by insects or may even puncture and kill insect iarvae. other
trichomes are sticky and glandular and effectively trap and immobilize insects.
牐牐營f the physical barriers of the plant are breached, then preformed chemicals may
inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or
potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of
which are highly effective deterrents to insects that feed on plants. the success of the
colorado beetle in infesting potatoes, for example, seems to be correlated with its high
tolerance to alkaloids that normally repel potential pests. other possible chemical
defenses, while not directly toxic to the parasite, may inhibit some essential step in the
establishment of a parasitic relationship. for example, glycoproteins in plant cell walls
may inactivate enzymes that degrade cell walls. these enzymes are often produced by
bacteria and fungi.
牐牐燗ctive plant defense mechanisms are comparable to the immune system of
vertebrate animals, although the cellular and molecular bases are fundamentally
different. both, however, are triggered in reaction to intrusion, implying that the host
has some means of recognizing the presence of a foreign organism. the most dramatic
example of an inducible plant defense reaction is the hypersensitive response. in the
hypersensitive response, cells undergo rapid necrosis--that is, they become diseased
and die--after being penetrated by a parasite; the par asite itself subsequently ceases to
grow and is therefore restricted to one or a few cells around the entry site. several
theories have been put forward to explain the basis of hypersensitive resistance.
42. what does the passage mainly discuss?
(a) the success of parasites in resisting plant defense mechanisms
(b) theories on active plant defense mechanisms
(c) how plant defense mechanisms function
(d) how the immune system of animals and the defense mechanisms of plants differ
43. the phrase "subject to" in line 1 is closest in meaning to
(a) susceptible to
(b) classified by
(c) attractive to
(d) strengthened by
44. the word "puncture" in line 8 is closest in meaning to
(a) pierce
(b) pinch
(c) surround
(d) cover
45. the word "which" in line 13 refers to
(a) tissues
(b) substances
(c) barriers
(d) insects
46. which of the following substances does the author mention as not necessarily being toxic to the colordo beetle?
(a) resins
(b) tannins
(c) glycosides
(d) alkaloids
47. why does the author mention "glycoproteins" in line 17?
(a) to compare plant defense mechaisms to the immune system of animals
(b) to introduce the discussion of active defense mechanisms in plants
(c) to illustrate how chemicals function in plant defense
(d) to emphasize the importance of physical barriers in plant defense
48. the word "dramatic" in line 23 could best be replaced by
(a) striking
(b) accurate
(c) consistent
(d) appealing
49. where in the passage does the author describe an active plant defense reaction ?

牐牐燭he most financially rewarding of all the academy-institute awards are the mildred
and harold strauss livings. harold strauss, a devoted editor at alfred a. knopf, the
new york publishing house, and mildred strauss, his wife, were wealthy any childless.
they left the academy-institute a unique bequest: for five consecutive years, two
distinguished (and financially needy) writers would receive enough money so they
could devote themselves entirely to "prose literature" (no plays, no poetry, and no
paying job that might distract). in 1983, the first strauss livings of $35,000 a year
went to short-story writer raymond carver and novelist-essayist cynthia ozick. by
1988, the fund had grown enough so that two winners, novelists diane johnson and
robert stone, each got $50,000 a year for five years.

questions 31-41
牐牐 archaeological records-paintings, drawings and carvings of humans engaged in
activities involving the use of hands-indicate that humans have been predominantly
right-handed for more than 5,000 years. in ancient egyptian artwork, for example, the
right hand is depicted as the dominant one in about 90 percent of the examples. fracture
or wear patterns on tools also indicate that a majority of ancient people were right-handed.
牐牐燙ro-magnon cave paintings some 27,000 years old commonly show outlines of human
hands made by placing one hand against the cave wall and applying paint with the
other. children today make similar outlines of their hands with crayons on paper. with
few exceptions, left hands of cro-magnans are displayed on cave walls, indicating that
the paintings were usually done by right-handers.
牐牐燗nthropological evidence pushes the record of handedness in early human ancestors
back to at least 1.4 million years ago. one important line of evidence comes from
flaking patterns of stone cores used in toolmaking: implements flaked with a
clockwise motion (indicating a right-handed toolmaker) can be distinguished from
those flaked with a counter-clockwise rotation (indicating a left-handed toolmaker).
牐牐燛ven scratches found on fossil human teeth offer clues. ancient humans are thought
to have cut meat into strips by holding it between their teeth and slicing it with stone
knives, as do the present-day inuit. occasionally the knives slip and leave scratches on
the users teeth. scratches made with a left-to-right stroke direction (by right-handers)
are more common than scratches in the opposite direction (made by left-handers).
牐牐燬till other evidence comes from cranial morphology: scientists think that physical
differences
between the right and left sides of the interior of the skull indicate subtle
physical differences between the two sides of the brain. the variation between the
hemispheres corresponds to which side of the body is used to perform specific
activities. such studies, as well as studies of tool use, indicate that right- or left-sided
dominance is not exclusive to modern homo sapiens. population of neanderthals,
such as homo erectus and homo habilis, seem to have been predominantly
right-handed, as we are.
31.what is the main idea of the passage?
(a) human ancestors became predominantly right-handed when they began to use tools.
(b) it is difficult to interpret the significance of anthropological evidence concerning tool use.
(c) humans and their ancestors have been predominantly right-handed for over a million years.
(d) human ancestors were more skilled at using both hands than modern humans.
32.the word "other" in line 8 refers to
(a) outline
(b) hand
(c) wall
(d) paint
33.what does the author say about cro-magnon paintings of hands?
(a) some are not very old.
(b) it is unusual to see such paintings.
(c) many were made by children.
(d) the artists were mostly right-handed.
34.the word "implements" in line 13 is closest in meaning to
(a) tools
(b) designs
(c) examples
(d) pieces
35.when compared with implements "flaked with a counter-clockwise rotation" (line 15), it can be inferred that "implements flaked with a clock-wise motion" (line13-14) are
(a) more common
(b) larger
(c) more sophisticated
(d) older
36 the word "clues" in line 16 is closest in meaning to
(a) solutions
(b) details
(c) damage
(d) information
37 the fact that the inuit cut meat by holding it between their teeth is significant because
(a) the relationship between handedness and scratches on fossil human teeth can be verified
(b) it emphasizes the differences between contemporary humans and their ancestors
(c) the scratch patterns produced by stone knives vary significantly from patterns produced by modern knives
(d) it demonstrates that ancient humans were not skilled at using tools
38 the word "hemispheres" in line 24 is closest in meaning to
(a) differences
(b) sides
(c) activities
(d) studies
39 why does the author mention homo erectus and home habilis in line 27?
(a) to contrast them with modern humans
(b) to explain when human ancestors began to make tools
(c) to show that early humans were also predominantly right handed
(d) to prove that the population of neanderthals was very large
40 all of the follows are mentioned as types of evidence concerning handedness except
(a) ancient artwork
(b) asymmetrical skulls
(c) studies of tool use
(d) fossilized hand bones
41 which of the following conclusions is suggested by the evidence from cranial morphology(line 21)?
(a) differences in the hemispheres of the brain probably came about relatively recently.
(b) there may be a link between handedness and differences in the brain s hemispheres
(c) left-handedness was somewhat more common among neanderthals
(d) ariation between the brain hemispheres was not evident in the skill of home erectus and home habilis
questions 42-50
牐牐燩lants are subject to attack and infection by a remarkable variety of symbiotic
species and have evolved a diverse array of mechanisms designed to frustrate the
potential colonists. these can be divided into preformed or passive defense mechanisms
and inducible or active systems. passive plant defense comprises physical and chemical
barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable
or toxic to the invader. the external surfaces of plants, in addition to being covered by
an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which
either prevent feetling by insects or may even puncture and kill insect iarvae. other
trichomes are sticky and glandular and effectively trap and immobilize insects.
牐牐營f the physical barriers of the plant are breached, then preformed chemicals may
inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or
potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of
which are highly effective deterrents to insects that feed on plants. the success of the
colorado beetle in infesting potatoes, for example, seems to be correlated with its high
tolerance to alkaloids that normally repel potential pests. other possible chemical
defenses, while not directly toxic to the parasite, may inhibit some essential step in the
establishment of a parasitic relationship. for example, glycoproteins in plant cell walls
may inactivate enzymes that degrade cell walls. these enzymes are often produced by
bacteria and fungi.
牐牐燗ctive plant defense mechanisms are comparable to the immune system of
vertebrate animals, although the cellular and molecular bases are fundamentally
different. both, however, are triggered in reaction to intrusion, implying that the host
has some means of recognizing the presence of a foreign organism. the most dramatic
example of an inducible plant defense reaction is the hypersensitive response. in the
hypersensitive response, cells undergo rapid necrosis--that is, they become diseased
and die--after being penetrated by a parasite; the par asite itself subsequently ceases to
grow and is therefore restricted to one or a few cells around the entry site. several
theories have been put forward to explain the basis of hypersensitive resistance.
42. what does the passage mainly discuss?
(a) the success of parasites in resisting plant defense mechanisms
