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 in 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, 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 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 visitor Hong Kong offers both East and West. You can go shopping, try

PASSAGE 2 - Questions 11 –20
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 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 looking at the peasants,
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 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 the failure
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 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 ; and 3) they have a unique chemical crystal structure
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 are composed of the same element (carbon), but the former isgraphite 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 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 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.

PASSAGE 1 – Questions 1-10
Buddhism comes from the word Buddha. Buddha was a person who lived more than two
thousand five hundred years ago in India. His family was rich and he lived in a beautiful
house with many servants. One day when he went out of his house, he looked at the
people and asked himself these questions, “Why are people so unhappy? How can people
be happy?”
When he was twenty nine years old, he left his family and his beautiful home and went
out into the world to find the answers to his questions. First, he studied with teachers but
they did not answer his questions. After this, he lived by himself in the forest and he did
not eat for many days. He tried to get away from his body and the world but this did not
give him the answers to his questions. Then he sat down under a tree and he thought. He
sat and thought for forty-nine days and after this time he learned something from himself.
He became the Buddha. His questions were answered.
People are unhappy because they want things. They are always looking for food, money
and other things. When people do not want things, then they will be happy. When people
do not want things, they are free. They stop thinking about themselves. They stop
thinking about tomorrow and they are kind to others. These are the teachings of Buddha.
Buddha’s teachings were not written down until two or three hundred years after his
death. Before this, people just remembered and told them to others.
Buddha died when he was eighty years old. During his long life, he travelled to many
places and had many followers. A follower of Buddha is called a Buddhist and some
Buddhist men become monks. Monks do not work and they do not have money. They cut
off all their hair and they wear only a long piece of yellow cloth. They usually do not
wear anything on their feet. Early in the morning, monks walk along the street carrying a
bowl. They cannot ask for food but people stop them and give them food. The life of a
monk is not easy. They spend their time spraying and thinking and trying to get away
from the world. They try to follow the teachings of Buddha.
8AIn Thailand, any man can be a monk and many become monks for a short time,
usually the three months of the wet season. 8B They leave their families and go to live
and study in a temple. 8CAfter three months they go back to their own lives, although
some remain monks and study the teachings of Buddha their whole lives.8D
Since the time of the Buddha, women have also given their lives to Buddhism. These
women are called nuns. Some of them pray and study Buddhism, some study the great
Buddhist writings and others help the poor.
There is more than one kind of Buddhism. While all Buddhists follow the Buddha’s
teachings, Buddhism developed differently in each of the many countries it spread to.
Buddhism started in Asia but today it has spread to Western countries.

PASSAGE 2 – Questions 11-20
If you can read a clock, you can know the time of day. But no one knows what time itself
is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way
we mark its passing. For all our success in measuring the smallest parts of time, time
remains one of the great mysteries of the universe. One way to think about time is to
imagine a world without time. There could be no movement, because time and movement
cannot be separated. A world without time could exist only as long as there were no
changes. For time and change are linked. We know that time has passed when something
changes.
In the real world, the world with time, changes never stop. Some changes happen only
once in a while, like an eclipse of the moon. Others happen repeatedly, like the rising and
setting of the sun. Humans always have noted natural events that repeat themselves.
When people began to count such events, they began to measure time. In early human
history, the only changes that seemed to repeat themselves evenly were the movements of
objects in the sky. The most easily seen result of these movements was the difference
between light and darkness.
The sun rises in the eastern sky, producing light. It moves across the sky and sinks in the
west, causing darkness. The appearance and disappearance of the sun was even and
unfailing. The periods of light and darkness it created were the first accepted periods of
time. We have named each period of light and darkness: one day.
People saw the sun rise higher in the sky during the summer than in winter. They counted
the days that passed from the sun's highest position until it returned to that position. They
counted three hundred and sixty-five days. We now know that is the time Earth takes to
move once around the sun. We call this period of time a year.
Early humans also noted changes in the moon. As it moved across the night sky, they
must have wondered: Why did it look different every night? Why did it disappear? Where
did it go? Even before they learned the answers to these questions, they developed a way
to use the changing faces of the moon to tell time. The moon was "full" when its face was
bright and round and "new" when it was almost entirely dark. The early humans counted
the number of times the sun appeared between full moons. They learned that this number
always remained the same, about twenty- -nine suns. Twenty nine suns equalled one
moon. We now know this period of time as one month.
Early humans hunted animals and gathered wild plants. They moved in groups or tribes
from place to place in search of food. Then, people learned to plant seeds and grow crops.
They learned to use animals to help them work, and for food. They found they no longer
needed to move from one place to another to survive. As hunters, people did not need a
way to measure time. As farmers, however, they had to plant crops in time to harvest
them before winter. They had to know when the seasons would change. So, they were
forced to developed calendars. No one knows when the first calendar was developed. But
it seems possible that it was based on moons, or lunar months.
When people started farming, the wise men of the tribes became very important. They
studied the sky. They gathered enough information so they could know when the seasons
would change. They announced when it was time to plant crops.
11. Why is time such a difficult concept to understand?
A. it's always changing
B. it's always moving
C. it's been misunderstood since pre-history
D. it's not tangible (hữu hình)
12. How were early humans able to begin measuring time?
A. by counting the objects in the sky
B. by working both at night and during the day
C. the movements of objects they saw every day

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 in 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, 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 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 visitor Hong Kong offers both East and West. You can go shopping, try

PASSAGE 2 - Questions 11 –20
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 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 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 the failure
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 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.

establish the relationship between the mass and gravitational pressure.
24. What happens when compression increases?
A. The hydrogen and helium fuel has been burned

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 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 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.
31. According to paragraph 1, which of the following is a characteristic of mineral? A. Crystal structure B. Organic matter C. Hardness D. Smooth surface
32. The word “the latter” in the passage refers to A. Mineral B. Diamond C. Graphite D. Carbon

PASSAGE 1 – Questions 1-10
Buddhism comes from the word Buddha. Buddha was a person who lived more than two
thousand five hundred years ago in India. His family was rich and he lived in a beautiful
house with many servants. One day when he went out of his house, he looked at the
people and asked himself these questions, “Why are people so unhappy? How can people be happy?”
When he was twenty nine years old, he left his family and his beautiful home and went
out into the world to find the answers to his questions. First, he studied with teachers but
they did not answer his questions. After this, he lived by himself in the forest and he did
not eat for many days. He tried to get away from his body and the world but this did not
give him the answers to his questions. Then he sat down under a tree and he thought. He
sat and thought for forty-nine days and after this time he learned something from himself.
He became the Buddha. His questions were answered.
People are unhappy because they want things. They are always looking for food, money
and other things. When people do not want things, then they will be happy. When people
do not want things, they are free. They stop thinking about themselves. They stop
thinking about tomorrow and they are kind to others. These are the teachings of Buddha.
Buddha’s teachings were not written down until two or three hundred years after his
death. Before this, people just remembered and told them to others.
Buddha died when he was eighty years old. During his long life, he travelled to many
places and had many followers. A follower of Buddha is called a Buddhist and some
Buddhist men become monks. Monks do not work and they do not have money. They cut
off all their hair and they wear only a long piece of yellow cloth. They usually do not
wear anything on their feet. Early in the morning, monks walk along the street carrying a
bowl. They cannot ask for food but people stop them and give them food. The life of a
monk is not easy. They spend their time spraying and thinking and trying to get away
from the world. They try to follow the teachings of Buddha.
8AIn Thailand, any man can be a monk and many become monks for a short time,
usually the three months of the wet season. 8B They leave their families and go to live
and study in a temple. 8CAfter three months they go back to their own lives, although
some remain monks and study the teachings of Buddha their whole lives.8D
Since the time of the Buddha, women have also given their lives to Buddhism. These
women are called nuns. Some of them pray and study Buddhism, some study the great
Buddhist writings and others help the poor.
There is more than one kind of Buddhism. While all Buddhists follow the Buddha’s
teachings, Buddhism developed differently in each of the many countries it spread to.
Buddhism started in Asia but today it has spread to Western countries.

PASSAGE 2 – Questions 11-20
If you can read a clock, you can know the time of day. But no one knows what time itself
is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way
we mark its passing. For all our success in measuring the smallest parts of time, time
remains one of the great mysteries of the universe. One way to think about time is to
imagine a world without time. There could be no movement, because time and movement
cannot be separated. A world without time could exist only as long as there were no
changes. For time and change are linked. We know that time has passed when something changes.
In the real world, the world with time, changes never stop. Some changes happen only
once in a while, like an eclipse of the moon. Others happen repeatedly, like the rising and
setting of the sun. Humans always have noted natural events that repeat themselves.
When people began to count such events, they began to measure time. In early human
history, the only changes that seemed to repeat themselves evenly were the movements of
objects in the sky. The most easily seen result of these movements was the difference between light and darkness.
The sun rises in the eastern sky, producing light. It moves across the sky and sinks in the
west, causing darkness. The appearance and disappearance of the sun was even and
unfailing. The periods of light and darkness it created were the first accepted periods of
time. We have named each period of light and darkness: one day.
People saw the sun rise higher in the sky during the summer than in winter. They counted
the days that passed from the sun's highest position until it returned to that position. They
counted three hundred and sixty-five days. We now know that is the time Earth takes to
move once around the sun. We call this period of time a year.
Early humans also noted changes in the moon. As it moved across the night sky, they
must have wondered: Why did it look different every night? Why did it disappear? Where
did it go? Even before they learned the answers to these questions, they developed a way
to use the changing faces of the moon to tell time. The moon was "full" when its face was
bright and round and "new" when it was almost entirely dark. The early humans counted
the number of times the sun appeared between full moons. They learned that this number
always remained the same, about twenty-nine suns. Twenty-nine suns equalled one
moon. We now know this period of time as one month.
Early humans hunted animals and gathered wild plants. They moved in groups or tribes
from place to place in search of food. Then, people learned to plant seeds and grow crops.
They learned to use animals to help them work, and for food. They found they no longer
needed to move from one place to another to survive. As hunters, people did not need a
way to measure time. As farmers, however, they had to plant crops in time to harvest
them before winter. They had to know when the seasons would change. So, they were
forced to developed calendars. No one knows when the first calendar was developed. But
it seems possible that it was based on moons, or lunar months.
When people started farming, the wise men of the tribes became very important. They
studied the sky. They gathered enough information so they could know when the seasons
would change. They announced when it was time to plant crops.
11. Why is time such a difficult concept to understand? A. it's always changing B. it's always moving
C. it's been misunderstood since pre-history
D. it's not tangible (hữu hình)
12. How were early humans able to begin measuring time?
A. by counting the objects in the sky
B. by working both at night and during the day
C. the movements of objects they saw every day
D. by following the sun to the west
13. The word “it” in paragraph 3 refers to A. The sun B. The eastern sky C. light D. darkness
