Read the following passage and choose the best answer for each of the questions.

Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include lass of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.

Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.

All the major organs of the body show signs of aging. The brain , for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.

One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack.

Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves may times during the course of a lifetime. Nerve cells and muscle fibers can never be replace once they wear out.

Gerontologists- scientists who study the process of aging- believe this wearing out of the body is controlled by a built- in biological time clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.

1. What does the word “it” in line 2 refer to?

A. aging B. a living thing C. an illness D. an accident

2. All the followings may be the outward signs of aging EXCEPT ________.

A. the graying of the hair B. the wrinkling of the skin

C. the decline in hearing and eyesight. D. the loss of appetite

3. When does the human body begin to lose vigor and the ability to function efficiency?

A. Soon after reaching adulthood B. During childhood

C. Early adulthood D. Past middle age

4. What happens to memorization when the brain begins to age?

A. It works less B. It becomes forgetful

C. It declines D. It slows down

5. According to the passage, which of the following is NOT true?

A. All living things grow old.

B. Aging is unavoidable in any livings things.

C. Plants show less signs of aging than any other living things.

IV. In the following text, six sentences or parts of sentences have been removed. Above
the extract you will find the six removed sentences PLUS one sentence which doesn't fit.
Choose from the sentences (A-G) the one which fits each gap (1-6). Remember, there is
one extra sentence you do not need to use. Write the correct letter in the box.
Choose from the following sentences to fill the spaces in the text. There is ONE extra.
A. Using a microwave for cooking a large food mass is difficult due to limited penetration of
microwaves.
B. This can be overcome by leaving the food to stand for a few minutes when cooking is
completed.

C. It is advised that the water should be poured slowly into another container that already
contains the powder.
D. In this way, buying a microwave oven with a turntable ensure the food is cooked
throughout.
E. Conversely the microwaves do not heat glass, ceramic and plastic containers.
F. If the microwaves are not absorbed inside the oven, the oven can be damaged by
electrical arcs and overheating of the microwave source.
G. When water in that state is disturbed, it can suddenly and unexpectedly boil violently.
MICROWAVING
Microwaving is a method of cooking where food is bombarded by microwaves, usually
within an appliance called a microwave oven which excite the water, fat and sugar
molecules, thereby heating (cooking) both the outside and center of the food at the same
time. (1)…………………
(A common myth is that a microwave oven cooks from the center of the food outward. This
appears to happen because heat generated at the surface escapes more readily from the
surface of the food into the surrounding air.) One advantage of microwaving is that small
amounts of food can be heated very quickly, making it useful for reheating leftovers.
The disadvantage is that food which is microwaved does not undergo some of the chemical
reactions, such as browning, which makes the food visually attractive. Primitive microwave
ovens often do not cook evenly, leading to a concern that bacteria easily killed by more
traditional cooking methods may survive the quick cooking time in "cold spots", though the
food item as a whole is cooked to a safe average temperature. (2) ……
Some high-end microwave ovens are combined with a convection oven which basically
cook the food using microwave and hot air simultaneously to achieve both the fast cooking
time and browning effect.
(3) …………………
However microwave ovens are used in some fast food chains and special microwave bags
are available for cooking fowl or large joints of meat.
Professional chefs generally recommend using microwaves for a limited set of tasks,
including: melting fats (such as butter) and chocolate, cooking grains like oatmeal and grits,
cooking rice, thawing frozen meats and vegetables before cooking by other methods and
quickly reheating already-cooked foods.
Using a microwave to boil water is potentially dangerous, due to superheating. In a
microwave, water can be raised quickly to a temperature above the boiling point before
major bubbles form, especially if it is purified and in a very clean glass vessel. (4)
…………………
This effect is rare, even for scientists who try to deliberately recreate it, and any seed
whatsoever for boiling is likely to prevent the problem. Boiling water with, for instance, a
teabag already in it will prevent any dangers by providing a seed, as will using a mug that is
not perfectly clean.

The risk greatly increases when water has already been boiled once in the same container.
This situation can occur if the user of the oven boiled the water once, forgot about it, then
came back later to boil it again. The first time the water boils, the seed bubbles
(microscopic bubbles of air around which larger steam bubbles grow) are used up and
largely eliminated from the water as it cools down. When the water is heated again, the lack
of seed bubbles causes superheating, and a risk of a steam explosion when the water's
surface is disturbed.
Placing something in the water before heating can mostly alleviate this risk. If you are
planning to mix something with the water, say tea or hot chocolate, adding it before heating
will insure that the water boils. Otherwise, placing a wood object, for instance a chopstick,
in the water before heating will also work.
Care should be taken when removing heated water from a microwave. Make sure that the
hands are protected from possible liquid boil-over, place the container on a level, heat-
proof surface and stir liquid with a warm spoon. Also, never add powdered substances
(such as instant coffee or cocoa mix) to the container taken from the microwave, due to the
addition of all those seed bubbles and the potential for violent, spontaneous boiling. (5)
…………………
Metal objects, such as metal utensils, in a microwave oven can lead to dangerous situations.
Metals do not absorb microwaves effectively. Instead, metals reflect microwaves, thereby
preventing the latter from reaching the food. (6) …………………
Thin metal layers, such as metal foil and mugs with metal trim can melt or burn due to the
strong electrical currents that are generated in metal objects. However, small solid metal
objects, such as spoons, in combination with a large amount of absorbing food or liquid,
normally do not lead to problems.

When it rains, all of the water stays inside it and typically drains into the subsurface. It can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep. ______ 2. A tornado B. The Earth has a crust under the oceans and the land that we live on. This crust made of massive areas of flat rock called tectonic plates, which float on the Earth’s mantle, the inside layer of the Earth. When the plates move slowly together, this movement forces energy through the crusts to the Earth’s surface. The energy causes the Earth to tremble and shake. ______ 3. A hurricane C. It is a very bright flash of electricity that happens in a thunderstorm. It is actually a spark that crosses the gap between two clouds or between a cloud and the Earth. It carries an enormous charge of electricity. Trees are burned, metal can be melted and people can be killed. ______ 4. An earthquake D. It is caused by earthquakes at sea. It forms when energy from an earthquake displace hundreds of cubic kilometers of water from the seabed. Large waves begin moving through the ocean from their epicenters. When it reaches shallow water near coastal areas, it increases in height. The sign comes before it strikes when the waterline suddenly retreats, exposing hundreds of meters of beach and seabed. ______ 5. A volcano E. It is a very violent windstorm. The air is concentrated and whirls up rapidly. It is grey in colour and looks like an elephant’s trunk swaying down from the clouds to touch the ground with its tip. ______ 6. A tsunami F. It is a hill or mountain formed when molten material or lave from the inside of the Earth is forced through the Earth’s crust by gases. It can produce vast clouds of very fine volcanic dust which looks like smoke. ______ 7. A sinkhole G. It is a storm where you hear thunder and see lightning. There is usually heavy rain. It is an electric storm. ______ 8. Lightning H. It is the most violent storm known on Earth. It is a tropical storm. It forms at sea and causes dangerous, stormy seas. It can reach the land and destroy buildings and trees. It can blow high waves onto the land and cause flooding. II.

We are nowadays becoming more aware of pollution matters that affect dramatically our lives; especially there is growing concern about air pollution. There are some reasons that lead to this kind of pollution. Firstly, the development of industrial zones, factories and building construction areas is producing a large amount of dust and poisonous air. Especially in the developing countries, people rarely pay their attention to the air treatment process that make the air pollution condition even worse. Secondly, because of the increasing unrbanization, it can be easily seen that there is always a lot of traffic in rush hour and dust one the road these days. The smoke from vehicles and manufacturing exhaust increase the amount of carbon dioxide in the air which makes us feel really hard to breathe. The consequences are very bed. Smog and dust can do serious harm to our health and especially our lungs. We have thousands of asthma and adult respiration distress cases each year which raise concern about the air quality. Moreover, acid rains are becomning more and more popular which damage crops and fields. Many people believe that air pollution is also causing global warming and it is difficult to improve the air without the efforts of all countries around the world.

There are two types of air pollution. That is the outdoor air pollution caused by factories, automobiles and biological matter. We most commonly associate air pollution with smog and acid rain. That is of course a problem and you might be surprised how aware children are of the air pollution concerns. However, there is also indoor air pollution. Indoor air pollution causes just as many health problems around the globe as outdoor air pollution. And because many people are not aware of it, they suffer unnecessarily. According to the World Health Organization, 2.4 million people die each year from air pollution and 1.5 million of these deaths are caused by indoor air pollution. Educating young kids about air pollution can be an efficient solution to this alarming worldwide issue because it can make them somewhat aware of air pollution. They may have heard about the greenhouse effect, global warming and acid rain. These problems may be frightening for children to hear. However, children also have the power to make changes both inside their home and globally.

Question 1. Choose ONE appropriate question in the box to each paragraph below:

1/ How do industry and transport cause pollution?
2/ How can I help?
3/ What is the pollution?
4/ How can industry help?
5/ What cause pollution?
6/ What about air pollution?

A. _3__ Pollution is the poisoning of the land, sea and air.
B. __5_ Mainly industry and transport. If you go to any city, you will see too many
factories, too many cars with not enough people in them, and not enough public transport.
C. __1_ Factories and vehicles produce waste which goes into the air and rivers and
spreads all over the land. Poisons in the waste build up over the years and harm trees,
plants, animals, and people.
D. _6__ Waste gases build up in the air, and dissolve into raindrops, forming a weak
acid. This "acid rain" can fall far away from the country which produced it, killing trees in
forests and fish in lakes and rivers.

E. _4__ If companies clean their waste gases before releasing them into the
atmosphere, there'll be much less air pollution and no acid rain. But this can be expensive
and it needs all the world's companies to do it.
F. _2__ Cars pollute the atmosphere. Walk, cycle and use public transport as much as
possible. Only use your car when you really need to, and use unleaded petrol if you can -
lead is one of the most dangerous ingredients in petrol. Join us, and help us to campaign for
cleaner air for everybody.
