Read the passage and then choose the best answer.

The British ship H.M.S Breadalbane sank in the Canadian Arctic on August 21 1853, after being crushed by encroaching ice while on a rescue mission. The 31 crewmen aboard escaped over the ice to a companion vessel as the Breadalbane went down in 15 minutes.

Canadian scientists now report that after a three-year search of records about the ship, they have located it sitting upright in 110 meters of water. Using a robot camera device, they said they have taken remarkably clear pictures of the Breadalbane, which has been well preserved by the ice and the supercold water "What we have is a treasure trove of 19th century Arctic exploration." reported one scientist. Located 1000 kilometers above the Arctic Circle, the Breadalbane is the world's northernmost known shipwreck.

According to the passage, the Breadalbane was sailing where it was on August 21, 1853, mainly to
A. explore the area in which it sank. B. defend that area for the British government.
C. find a northwest passage to the Orient. D. save the lives of other people.

What happened to the Breadalbane's crew?
A. Some survived but most perished. B. Most survived but a few perished.
C. All perished in the accident. D. All were rescued by another ship.

The scientists can prove they have found the exact location of the Breadalbane because they
A. have taken underwater photos of the ship.
B. dived down to the wreck to explore it
C. managed to refloat the boat using modern engineering techniques.

D. retrieved some objects from the wreck with the ship's name on them.

The reason that the scientists called the wreck a "treasure trove" is that they expect it to yield a lot of

A. precious metals. B. valuable foreign goods. C. precious stones. D. valuable information.

The main reason that they can be sure to expect to learn a great deal about 19th century Arctic exploration from the wreck is that
A. no other ship ever sank in waters so far north.
B. water currents are gentle there so the ship was not moved.
C. the camera they are using is a robot.
D. the ship has been extremely well preserved by the severe cold.

The principal historical distinction of this wreck when compared with other is that
A. it has lain underwater for so long.
B. the scientists expect to become wealthy from its discovery.
C. no other has been found so far north.
D. until now it has been impossible to take pictures in such icy waters.

Read the paragraphs below and the summary which follows. (3ms)

Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn’t enuogh information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases.

The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere can’t think as quickly as other children and are clumsy when they use their hands.

There are other long-term effects of pollution. If the gases in the atmosphere continue to increase , the earth’s climate may become warmer. A lot of the ice near the Poles ma melt and may cause serious floods.

* Complete the summary by writing the correct word in each blank (write one word only.)

Air ___________ (52) can make people ___________ (53). Consequently, some countries pass ____________ (54) to control the quantity of ___________ (55) in the air. Air pollution causes particular damage to the body by harming the ___________ (56). _____________ (57) should not be used in petrol because it is bad for children’s _____________ (58) and makes them clumsy in using their hands. Poisonous gas from ____________ (59) collects in those parts of cities where there are tall buildings. Pollution can also have an influence on the earth’s ____________ (60). The ice may melt near the North and South Poles, resulting in very bad ____________ (61).

II/ Read the passage and answer the question :
Air pollution is a serious problem in many cities. Motor vehicles, factories and other source create so
much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the
people who live in cities. City wastes cause water pollution when they are poured into the waterways.
These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have
difficulties in disposing their garbage. The amount of garbage grows each year, but places to put it are
quickly filling up Citizens, governments, industries, scientists and business people must work
together in different ways to gradually reduce pollution.
True ( T ) or False ( F ) in the space provided
1/ Air pollution is a serious (dangerous) problem in many cities . __________
2/ Air pollution doesn't cause danger to people's health in some cities
3/ Motor vehicles and factories are some of sources of air pollution . ____________
4/ Only factories are the main source of air pollution ._________
5/ Air pollution is the only problem of the environment in this passage .
6/ Some areas are unfit for swimming because of the city wastes .____________
7/ The amount of the garbage in large cities reduces each year ._________
8/ Everyone must cooperate to reduce pollution . ______________

III/ Read the passage and answer the question :
Everyone wants to reduce pollution, but the pollution problem is as complicated as it is serious.
It is complicated because much pollution is caused by things that benefit people. For example,
exhaust from motorbikes causes large percentage of air pollution. But the automobile provides
transportation to millions of people. Factories discharge much of the material that pollutes air
and water, but factories give employment to a large number of people.
Thus, to end or reduce pollution immediately, people would have to stop using many things that
benefit them . Most people do not want to do that, of course. But pollution can be gradually
reduced in many ways. Scientists and engineers can work to find ways to lessen the amount of
pollution that such things as automobiles and factories cause. Governments can pass and enforce
laws that require businesses and individuals to stop or to cut down on certain polluting activities.
True ( T ) or False ( F ) :
1. All people want to reduce pollution_____
2. Pollution problem is neither complicated nor serious_____
3. Pollution is brought about by things that benefit people_____

4. People have to sacrifice what they have to stop or reduce pollution_____
5. The government can't do anything to stop or reduce pollution.______
IV/ Read the passage and answer the questions:
Every day on radio, on TV and in the newspapers, we hear , see, read about many problems in
the world , for example , pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars,
airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere even
in the city where many people are living. The second pollution is sea pollution. Many people earn
their living from fishing the sea, and the fish they catch feed many people. But the sea has become so
polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the
fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more
difficult every day. We must find a good solution that makes the world a better place to live.
True — False — Not given?
1. Pollution is one of the city's problems_____
2. Exhaust fume comes from vehicles , airplane and factories_____
3. People pollute seas from dynamite fishing____
4. You can find easily a place nowadays that is not polluted_____

SECTION III: READING (5.0 points)
Part 1: Read the following passage and choose the correct answer to each of the following
questions. Write your answer (A, B, C, or D) in the numbered boxes.
Since ancient times, one of the most common materials people have utilized to make things
with is wood. Wood is used to make houses, buildings, and other structures. People also
make a large number of smaller objects with it.
The desire to make finished products more beautiful appears to be ingrained in huma n
nature. On account of this fact, for thousands of years, people have carved and shaped
wooden objects to make them more appealing to the eye. Humans have additionally tended
to create both religious and ceremonial objects from wood. In fact, all around the world,
countless cultures have made use of ceremonial wood carvings. These objects often reflect
the spirit of the people who made them, and each of them tends to hold a special
significance as well.
One of the most common types of wood carvings is the mask. People in many cultures in
Asia, Africa, and North America have made ceremonial wooden masks. In Africa, for
instance, large numbers of tribes use wooden masks for vari ous spiritual rituals. These
masks are often in the form of animals that are sacred to the tribes. In other cases, the masks
have human forms. The faces, however, may not be exactly humanlike. For instance, the
faces can be distorted, having wider, longer, smaller, or larger features than normal. The
masks may be carved to give them ugly or frightening appearances as well. And, on other
occasions, the masks are made to look as beautiful as possible.
While masks tend to be fairly small, other wood carvings can be enormous. Among the
largest of all ceremonial wood carvings is the totem p ole. Totem poles have been built by
several Native American tribes that reside in the northwestern part of North America. They
are normally made to represent families, or they may honor significant historical events.
Some even tell stories. A typical totem pole has several individual carvings on it. Each
carving represents a different part of the family history, event, or story. Most totem poles
have human or animal faces, as well as other figures, carved in them. They are so large that
they are made from e ntire trees. Once the trees are cut down, master craftsmen work on
them. When completed, they may or may not be painted. Then, the totem poles are
positioned in places of honor and placed upright.

1. What is this passage mainly about?
A. The ways wood can be used to make buildings B. The purposes of masks in some cultures
C. The types of wood carvings some people make D. Totem poles and their significance
2. In line 4, the word ingrained is closest in meaning to _________.

A. important to B. hunted by C. revered by D. necessary for
5. What does the author say about masks?
A. They always resemble human faces. B. It takes a great deal of effort to make them.
