PASSAGE 1 – Questions 1-10
Hong Kong is the name of an island off the coast of mainland China. The
biggest and most important city on Hong Kong is Vitoria, but not many
people use this name. People usually call the city Hong Kong too. Even
though Hong Kong is small, only about 1000 square kilometers, around
seven million people live there today. Hong Kong has a very interesting
history. Many years ago the island of Hong Kong belonged to China and
now it belongs to China again. However, for more than 150 years, Hong
Kong was ruled by the British.
Hong Kong has a very good port and in the middle of the 19th century,
lOMoARcPSD| 60692662
British ships often stopped there. They came to China to trade. However,
in 1839 a war began between China and Britain which continued for three
years. In 1842 the Chinese and the British held a meeting which ended the
war. At the meeting, the island of Hong Kong was given to Britain. Fifty
years later, 1898, China gave the area around Hong Kong to the British
for 99 years. In 1997 the British returned Hong Kong to China but it was
a very different place from the deserted island of 150 years ago.
Not many people lived in Hong Kong when it was first given to Britain.
Most of the people were Chinese farmers and fishermen and soon more
Chinese arrived. Some of them left China because they could not find
work there and others came to Hong Kong when there was a war in China.
All of these people came to find a better life for themselves and their
children. Beside the Chinese, many other people came. They came from
India, Britain, Holland and many other countries. After some years they
began to think of Hong Kong as their home and they began to work hard
for their new home. They too wanted to make a better life for their
families.
People began to build factories and many kinds of things were produced
such as clothes, medicines, machines and radios. These things were not
only sold in Hong Kong but also to many other countries. Hong Kong
soon became famous as a world centre for buying and selling, and it has
continued to get stronger and stronger.
7A In 1997, When Britain returned Hong Kong to China, there were many
differences between the Hong Kong way of life and the Chinese way of
life and people thought there might be some problems. 7B Many people
lOMoARcPSD| 60692662
from Hong Kong didn’t want to live by the Chinese rules. 7CMeetings
between the leaders of both countries were held and it was decided that
Hong Kong would be ruled by “One country, two systems”.
7D
Today, Hong Kong is a world centre for trade and banking. There are
world famous universities teaching in both English and in the Chinese
language of Cantonese. The port is one the the finest in the world and the
beautiful city of Victoria is built surrounding hills. For the visistor Hong
Kong offers both East and West. You can go shopping, try food from many

PASSAGE 2 - Questions 1120
Constellations are patterns of stars in the sky. Over many thousands of
years, human beings living on the Earth have looked up and seen the
shapes of people, animals and everyday objects - they 'joined the dots' of
the stars to form patterns in the sky. They gave these shapes names, some
of which we still use today. But why did they bother with constellations
at all? One reason is that having constellations makes it easier to find your
way around the sky. This is useful for finding north, or working out the
date or the time. When there were no compasses, clocks or watches, this
was all very important.
There is another reason why constellations were so important. Imagine
going back to a time before paper and pencil had been invented. Life was
sparse. If you wanted to draw a picture, you had to scratch it out on a dark
cave wall or write it in sand that could blow away. But at night an amazing
pattern of bright specks of light would appear above your head. By joining
the dots you could see almost any picture you wanted. You could imagine
seeing your favourite shapes in the sky. You might tell others about the
constellations you have made up. They might tell others, and your
constellation could be passed down from generation to generation for
hundreds or even thousands of years. This is how many of the
constellations got the names we use.
You don't see exactly the same part of the sky every night, though between
one night and the next you won't see much of a difference. Over a few
weeks you'll definitely notice that you can see some constellations that
you couldn't see before and some constellations that you could see aren't
there any more. This is because the Earth is moving around the Sun. As
the Earth moves round in its orbit, the night side of the Earth (the side
lOMoARcPSD| 60692662
facing away from the Sun) faces out to different parts of space, where
there are different constellations.
This means that you see different constellations in different seasons. Orion
and Taurus are (Northern Hemisphere) winter constellations, because you
can see them on winter evenings. Cygnus and Scorpius are (Northern
Hemisphere) summer constellations, because you can see them on
summer evenings.
So who made up the constellations and their names? The earliest people
on the Earth were hunters and gatherers. They looked up into the sky and
saw shapes that were important to them - like Orion the
Hunter. Much later in human history, English farmers looked up into the
sky and saw the shape of a Plough. Russian peasants, looking at the same
group of stars, called it Ursa Major or The Great Bear. People in France
called it Le Casserole meaning the Saucepan. People in the USA called it
The Big Dipper meaning a soup ladle. All of these different names are
used today. The only people who have decided on one set of names for
the constellations are the astronomers. For example, they always call the
Plough 'Ursa Major', and never any of the other names.
They had to do this so that they all knew what other astronomers across
the world were talking about.
The stars in a constellation have nothing to do with each other; they can
be very, very far apart, even if they appear to be right next to each other
lOMoARcPSD| 60692662
in the sky. Imagine looking up while standing in a street. You might see
your hand next to a street light, which is next to the Moon, which is next
to a planet, which is next to a star. All of these things are far away from
each other, yet they can be next to each other when you look at them.
If you like, you can look up into the sky, join the dots and make up your
own constellations. Tell other people about your constellations. Maybe
one day people all around the world will be using one of your constellation
names!

PASSAGE 3 - Questions 21–30
The discoveries of the white dwarf, the neutron star, and the black hole,
coming well after the discovery of the red giant are among the most
exciting developments in decades because they may be well present
physicists with their greatest challenge since thefailure of classical
mechanics. In the life cycle of the star, after all of the hydrogen and helium
fuel has been burned, the delicate balance between the outer nuclear
radiation, pressure and the stable gravitational force becomes disturbed
and slow contraction begins. As compression increases, a very dense
plasma forms. If the initial star had mass of less than 1.4 solar masses (1.4
times the mass of our sun), the process ceases at the density of 1,000 tons
per cubic inch, and the star becomes the white dwarf. However, if the star
was originally more massive, the white dwarf plasma can’t resist the
gravitations pressures, and in rapid collapse, all nuclear of the star are
converted to a gas of free neutrons. Gravitational attraction compresses
this neutron gas rapidly until a density of 10 tons per cubic inch is reached;
at this point the strong nuclear force resists further contraction. If the
mass of the star was between 1.4 and a few solar masses, the process stops
here, and we have a neutron star. But if the original star was more massive
than a few solar masses, even the strong nuclear forces cannot resist the
gravitational crunch. The neutrons are forced into one another to form
heavier hadrons and these in turn coalesce to form heavier entities, of
which we as yet know nothing. At this point, a complete collapse of the
stellar mass occurs; existing theories predict a collapse to infinite density
and infinitely small dimensions Well before this, however, the surface
gravitational force would become so strong that no signal could ever leave
the star - any photon emitted would fall back under gravitational attraction
and the star would become black hole in space. This gravitational
collapse poses a fundamental challenge to physics. When the most widely
accepted theories predict such improbable things as infinite density and
infinitely small dimensions, it simply means that we are missing some
lOMoARcPSD| 60692662
vital insight. This last happened in physics in the 1930’s, when we faced
the fundamental paradox concerning atomic structure. At that time, it was
recognized that electrons moved in table orbits about nuclei in atoms.
However, it was also recognized that if charge is accelerated, as it must
be to remain in orbit, it radiates energy; so, theoretically, the electron
would be expected eventually to spiral into the nucleus and destroy the
atom. Studies centered around this paradox led to the development of
quantum mechanics. It may well be that an equivalent advance awaits us
in investigating the theoretical problems presented by the phenomenon of
gravitational collapse.
21. Which of the following things was first discovered?

neutron star, and the black hole are significant because these
discoveries
A.demonstrate the probability of infinite density and infinitely small
dimensions
lOMoARcPSD| 60692662

PASSAGE 4 – Questions 31-40
Minerals are naturally occuring solid substances formed by geologic
movements in the Earth. Their main defining characteristics are that 1)
they are inorganic (composed of non-living matter); 2) they have a crystal
structure; and 3) they have a unique chemical composition. The type of
mineral is determined both by its crystal structure and its chemical
composition. A crystal structure occurs when the atoms inside the mineral
are ordered in a geometric pattern that repeats itself throughout the
mineral. All crystal structures fit into one of 14 possible “lattice” regular
pattern arrangements of atoms, which lattices can be detected by X-rays.
A mineral’s physical traits are influenced by its crystal form. For example,
both diamond and graphite are composed of the same element (carbon),
but the former is the hardest mineral while the latter is soft. This is
because graphite’s crystal structure arranges the carbon atoms in sheets
that can slide past each other, while diamond’s carbon atoms are arrayed
in a strong, interlocking network.
Two minerals with identical crystal structures can have different chemical
compositions. Thus, halite and gelena share the same crystal structure but
are composed of different chemicals. Conversely, two minerals with the
same chemical ingredients can differ in their crystal structure. For
lOMoARcPSD| 60692662
example, pyrite and marcasite both are made of iron sufide, but the
arrangement of their atoms differs.
According to the International Mineralogical Association, 4,000 minerals
have been identified to date. Only about 150 of them are plentiful, and
about 50 are classified as “occasional”. The remainder are rarely found,
some consisting of only small grains of rock.
Minerals are often found as components of rocks, which may contain
organic matter as well. Some rocks, which consist wholly of one mineral,
such as calcite in limestone rock. Other rocks may host many minerals.
Almost all of the rocks visible today contain one or more of a group of
about 15 minerals, including quartz, mica, and felspa.
The kinds of minerals found in any given rock are determined by these
factors. First, the rocks chemical composition must be hospitable to
particular mineral. For example, rocks containing silicon will likely
contain quartz. Second, the conditions under which the rock was formed
will influence the kinds of minerals found in the rock. Thus, rock born
from volcanic movements at high temperatures and pressures may
contain granite. Third, mineral distribution is affected by the geological
stages through which the rock passed before reaching its present state. For
example, exposure to moisture and acids may decay some minerals and
cause others to take their place. During the changes from one ecological
stage to another, the rock may disintergrate into sand or soil.
Mineralogists classify minerals according to either physical properties or
chemical composition. Minerals have numerous measurable physical
properties. Hardness is measured on the “Mohs scale”, which ranks
lOMoARcPSD| 60692662
hardness from one to 10. Any mineral can be cut or marked by a mineral
with a higher ranking on the Mohs scale. Thus a diamond, with a rank of
10, can cut into quartz, with a rank of 7. Luster measures the reflection of
light by the surface of the mineral. Metals have a higher luster than
gypsum, which has a porous surface. Cleavage refers to the way a mineral
splits apart along its natural grain, and fracture refers to its breakage
against its natural cleavage planes. Streak is the color of the residue left
by a mineral as it is rubbed across a special plate. Specific gravity
measures the density of the mineral; it is computed by comparing the mass
of the mineral to the mass of an equal volumn of water.
Minerals can also be classified by their chemical characteristics. The most
frequently occuring minerals are called silicates because of their large
shares of silicon and oxygen. Almost all rocks fit this category. The second
most common minerals are carbonates, which contain carbon and oxygen.
Carbornates are found on the ocean floor as the deposits of decayed
plankton. Aother grouping, halides, are found where water has
evaporated, as in dried lake beds and landlocked seas such as the Great
Salt Lake in Utah. Other common classes include sulfates, oxides,
sulfides, and phosphates.

you couldn't see before and some constellations that you could see aren't
there any more. This is because the Earth is moving around the Sun. As
the Earth moves round in its orbit, the night side of the Earth (the side lOMoAR cPSD| 60692662
facing away from the Sun) faces out to different parts of space, where
there are different constellations.
This means that you see different constellations in different seasons. Orion
and Taurus are (Northern Hemisphere) winter constellations, because you
can see them on winter evenings. Cygnus and Scorpius are (Northern
Hemisphere) summer constellations, because you can see them on summer evenings.
So who made up the constellations and their names? The earliest people
on the Earth were hunters and gatherers. They looked up into the sky and
saw shapes that were important to them - like Orion the
Hunter. Much later in human history, English farmers looked up into the
sky and saw the shape of a Plough. Russian peasants, looking at the same
group of stars, called it Ursa Major or The Great Bear. People in France
called it Le Casserole meaning the Saucepan. People in the USA called it
The Big Dipper meaning a soup ladle. All of these different names are
used today. The only people who have decided on one set of names for
the constellations are the astronomers. For example, they always call the
Plough 'Ursa Major', and never any of the other names.
They had to do this so that they all knew what other astronomers across the world were talking about.
The stars in a constellation have nothing to do with each other; they can
be very, very far apart, even if they appear to be right next to each other lOMoAR cPSD| 60692662
in the sky. Imagine looking up while standing in a street. You might see
your hand next to a street light, which is next to the Moon, which is next
to a planet, which is next to a star. All of these things are far away from
each other, yet they can be next to each other when you look at them.
If you like, you can look up into the sky, join the dots and make up your
own constellations. Tell other people about your constellations. Maybe
one day people all around the world will be using one of your constellation names!

PASSAGE 3 - Questions 21–30
The discoveries of the white dwarf, the neutron star, and the black hole,
coming well after the discovery of the red giant are among the most
exciting developments in decades because they may be well present
physicists with their greatest challenge since thefailure of classical
mechanics. In the life cycle of the star, after all of the hydrogen and helium
fuel has been burned, the delicate balance between the outer nuclear
radiation, pressure and the stable gravitational force becomes disturbed
and slow contraction begins. As compression increases, a very dense
plasma forms. If the initial star had mass of less than 1.4 solar masses (1.4
times the mass of our sun), the process ceases at the density of 1,000 tons
per cubic inch, and the star becomes the white dwarf. However, if the star
was originally more massive, the white dwarf plasma can’t resist the
gravitations pressures, and in rapid collapse, all nuclear of the star are
converted to a gas of free neutrons. Gravitational attraction compresses
this neutron gas rapidly until a density of 10 tons per cubic inch is reached;
at this point the strong nuclear force resists further contraction. If the
mass of the star was between 1.4 and a few solar masses, the process stops
here, and we have a neutron star. But if the original star was more massive
than a few solar masses, even the strong nuclear forces cannot resist the
gravitational crunch. The neutrons are forced into one another to form
heavier hadrons and these in turn coalesce to form heavier entities, of
which we as yet know nothing. At this point, a complete collapse of the
stellar mass occurs; existing theories predict a collapse to infinite density
and infinitely small dimensions Well before this, however, the surface
gravitational force would become so strong that no signal could ever leave
the star - any photon emitted would fall back under gravitational attraction
– and the star would become black hole in space. This gravitational
collapse poses a fundamental challenge to physics. When the most widely
accepted theories predict such improbable things as infinite density and
infinitely small dimensions, it simply means that we are missing some lOMoAR cPSD| 60692662
vital insight. This last happened in physics in the 1930’s, when we faced
the fundamental paradox concerning atomic structure. At that time, it was
recognized that electrons moved in table orbits about nuclei in atoms.
However, it was also recognized that if charge is accelerated, as it must
be to remain in orbit, it radiates energy; so, theoretically, the electron
would be expected eventually to spiral into the nucleus and destroy the
atom. Studies centered around this paradox led to the development of
quantum mechanics. It may well be that an equivalent advance awaits us
in investigating the theoretical problems presented by the phenomenon of gravitational collapse.

PASSAGE 4 – Questions 31-40
Minerals are naturally occuring solid substances formed by geologic
movements in the Earth. Their main defining characteristics are that 1)
they are inorganic (composed of non-living matter); 2) they have a crystal
structure; and 3) they have a unique chemical composition. The type of
mineral is determined both by its crystal structure and its chemical
composition. A crystal structure occurs when the atoms inside the mineral
are ordered in a geometric pattern that repeats itself throughout the
mineral. All crystal structures fit into one of 14 possible “lattice” – regular
pattern – arrangements of atoms, which lattices can be detected by X-rays.
A mineral’s physical traits are influenced by its crystal form. For example,
both diamond and graphite are composed of the same element (carbon),
but the former is the hardest mineral while the latter is soft. This is
because graphite’s crystal structure arranges the carbon atoms in sheets
that can slide past each other, while diamond’s carbon atoms are arrayed
in a strong, interlocking network.
Two minerals with identical crystal structures can have different chemical
compositions. Thus, halite and gelena share the same crystal structure but
are composed of different chemicals. Conversely, two minerals with the
same chemical ingredients can differ in their crystal structure. For lOMoAR cPSD| 60692662
example, pyrite and marcasite both are made of iron sufide, but the
arrangement of their atoms differs.
According to the International Mineralogical Association, 4,000 minerals
have been identified to date. Only about 150 of them are plentiful, and
about 50 are classified as “occasional”. The remainder are rarely found,
some consisting of only small grains of rock.
Minerals are often found as components of rocks, which may contain
organic matter as well. Some rocks, which consist wholly of one mineral,
such as calcite in limestone rock. Other rocks may host many minerals.
Almost all of the rocks visible today contain one or more of a group of
about 15 minerals, including quartz, mica, and felspa.
The kinds of minerals found in any given rock are determined by these
factors. First, the rock’s chemical composition must be hospitable to
particular mineral. For example, rocks containing silicon will likely
contain quartz. Second, the conditions under which the rock was formed
will influence the kinds of minerals found in the rock. Thus, rock born
from volcanic movements at high temperatures and pressures may
contain granite. Third, mineral distribution is affected by the geological
stages through which the rock passed before reaching its present state. For
example, exposure to moisture and acids may decay some minerals and
cause others to take their place. During the changes from one ecological
stage to another, the rock may disintergrate into sand or soil.
Mineralogists classify minerals according to either physical properties or
chemical composition. Minerals have numerous measurable physical
properties. Hardness is measured on the “Mohs scale”, which ranks lOMoAR cPSD| 60692662
hardness from one to 10. Any mineral can be cut or marked by a mineral
with a higher ranking on the Mohs scale. Thus a diamond, with a rank of
10, can cut into quartz, with a rank of 7. Luster measures the reflection of
light by the surface of the mineral. Metals have a higher luster than
gypsum, which has a porous surface. Cleavage refers to the way a mineral
splits apart along its natural grain, and fracture refers to its breakage
against its natural cleavage planes. Streak is the color of the residue left
by a mineral as it is rubbed across a special plate. Specific gravity
measures the density of the mineral; it is computed by comparing the mass
of the mineral to the mass of an equal volumn of water.
Minerals can also be classified by their chemical characteristics. The most
frequently occuring minerals are called silicates because of their large
shares of silicon and oxygen. Almost all rocks fit this category. The second
most common minerals are carbonates, which contain carbon and oxygen.
Carbornates are found on the ocean floor as the deposits of decayed
plankton. Aother grouping, halides, are found where water has
evaporated, as in dried lake beds and landlocked seas such as the Great
Salt Lake in Utah. Other common classes include sulfates, oxides, sulfides, and phosphates.
