Tomatoes are full of nutrients and are an especially good source of antioxidants vitamins. In fact,
one serving of tomato will give you 40% of your recommendation daily allowance of vitamin C. Diets
rich in fruit and vegetable are associated with lowerrisks of many diseases and a diet which inludes
high intake of tomatoes has been shown to protect against prostate cancer. Tomatoes are by far the
richest source of lycopene, a powerful antioxidant. Lycopene is highest in processed tomato foods,
such as tomato puree, because they are concentrated.

Tornadoes occur throughout the world, but for reasons that scientists are not fully able to recognize,
the great majority occur in the United States. Approximately 700 tornadoes a year occur within the
US, and this comprises three-quarters of the worldwide total. Most of the tornadoes take place in
the midwest and in the southern states that border the Gulf of Mexico. The most devastating
tornado on record occurred on March 18 1925, in the states of Missouri, Illinois and Indiana.
Traveling at an average speed of 60 miles per hour, the winds at the centre of the storm swirled
around at considerably more than 200 miles per hour. A total of 689 people died, and countless
more were injured, at the hands of this killer storm.

A. Why 700 tornadoes occur annually ?
B. Why tornadoes mostly occur in the U.S ?
C. Why the gulf of Mexico is the source of tornadoes ?
D. Why tornadoes average sped is 60 miles per hour ?

In Marine habitats, a number of small creatures are involved in a ‘cleaning symbiosis. At least six
species of small shrimp, frequently brightly coloured, crawls over fish, picking off parasites and
cleaning injured areas. This is not an accidental occurrence, because fish are observed together
around these shrimp and stay motionless while being inspected. Several inspects of small fish
(wrasses) are also cleaners, nearly all of them having appropriate adaptations such as long snouts,
tweezer-like teeth and bright coloration. Strikig coloration probably communicates that these
animals are not prey.

Whether a tree is coniferous or deciduous, where it bears fruits or not, whether grows in the tropics
or in the temperature zone, every tree has three parts ; the roots, the trunk and the crown. The
roots the part of the tree underground, hold the tree firmly against windstorms and provide the tree
with food gathered from the soil. The trunk, which is the most important woody part of the tree, is
the body of the tree ; it carries the food from the roots to the branches. The crown of the tree
consists of the branches, the leaves, and the fruit of the tree. The leaves use the food sent from the
trunk for many purposes, one of which is a process called photosynthesis, the leaves absorb
carbondioxide from the atmosphere. The single progress is essential to human life because humans
breathe oxygen in order to exist.

The Catastrophe called the Great Dying, which occurred between the Permian and Trissic
periods wiped out 90 percent of the plant’s marine life and 70 percent of all plant and animal life.
The most recent popular scientific belief about what caused it was the impact of a large object from
space, but the examination of sediment and fossil deposited at the time has led two groups of
scientists to revise this belief.
Animals and plants both on land and in the sea were dying at the same time and apparently from
the same causes –“too much heat and too little oxygen. “ said Peter Ward a University of
Washington paleontologist. In their research published in Science and express, the groups found
increased levels of sulphur and depleted oxygen in the ancient rock. Ward and his team of
researchers from the United States and South Africa thought that the sulphur came from continued
volcanic eruptions in an area known as Siberian Trap. The eruptions warmed the Earth, trapped the
sunlight, and depleted oxygen in the air.
At the same time, the Earth’s shifting tectonics plates lowered the levels of the ocean, exposing
seabeds and releasing methane trapped in the sediment there, further increasing the global
warming. The temperature kept rising so that it got hotter and hotter until it reached a critical point
causing everything to die. Temperature ariund the world rose 8 degrees, killing off olants which
served as food for animals, there by starving them. In addition, oxygen levels dropped to about 16
percent of the atmosphere, whereas levels today are at 21 percent.
Therefore, it is believed that the widespread volcanic eruptions that led to global warming was
likely the cause of massive extinction 250 million years ago, not the impact of an asteroid or comet.

The view that women are better parents than men has shown itself to b true throughout history.
This is not to say that men are not of important in child rearing: indeed, they are most necessary if
children are to appreciate fully the role of both sexes. But women have proven themselves superior
parents as a result of their conditioning, their less aggressive nature and their generally better
communication skills.
From the time they are little girls, female learn about norturing. First with dolls and later perhaps
with younger brothers and sisters, girls are given the role of carer. Girls see their mothers in the
same roles so that it is natural that identify this as female activity. Boys, in contrast, learn
competitive roles far removed from what it means to nurture. While boys may dream of adventures,
girls, conditioning means they tend to see the future in term of raising families.
Girls also appear to be less aggressive than boys. In adulthood, it is men not women, who prove
to be the agressors in crime and war. Obviously, in raising children, a more patient, gentle manner is
preferable to be a more aggressive one. Altough there certainly exist gentle men and aggressive
women, by and large, female are les likely to resort to violence in attempting to solve problems.
Finally, women tend to be better communicators than men. This is shown in intelligence tests,
where females, or average, do better in verbal communication than males. Of course,
communication is of utmost importance in rearing children, as children tend to learn from and adopt
the communication styles of their parents.
Thus, while it is all very well to suggest a greater role for men in raising children, let us not forget
that women are generally better suited to the parents role.

Measles, a childhood disease, has caused sufferings to mankind for thousands of years.
However, the search for an effective measles vaccine, lasted two hundred years and has finally
ended in success. Now, for the first time, easels is a preventable disease. You may ask, 'How is
this important to children?
Every year measles kills twice as many Americans as polio now does. More children die from
measles than from any other common childhood disease. Also complications of some degree
occur in about one child out of six. Most complications include pneumonia and ear disorders.
Another after effect of measles - brain damage is less common, but it can have such serious
consequences that it deserves special attention.
Brain damage due to easels sounds like something far away from our experience. In reality,
it is no. Like any other injury, damage to the brain can be very slight or very severe. It is quite
possible that we have never seen or heard a child who has severe brain damage - the child
would either have died or would be in an institution. However, in medical research a relation
has been found between measles and such things as behavior problems, personality changes
and dulling of mental ability. For example, a child may be bad-tempered or a little slow to learn
after he has recovered from measles.

Alternative energy sources are becoming increasingly attractive as the energy crisis becomes
more severe. Solar heating systems, which use the sun's radiation as a source of energy, are a
promising alternative energy source- Nuclear power plants are already in operation in several
parts of the country. Government and private industry are even investigating the possibility of
capturing the power of ocean waves and tides for conversion into usable energy. Coal is once
again becoming an acceptable fuel as the nation searches for solutions to the energy shortage.
Even garbage is seen as a potential source of energy. In some communities, garbage is burned to
heat buildings and light-city streets.
21. The main information of the text is about....
A. the interest in alternative energy sources
B. potential solar heating systems
C. the operation of nuclear power plants
D. the search for energy from the sea
E. the use of coal to replace oil
22. Which of the following statements is TRUE about alternative sources of energy?
A. Garbage can be recycled into energy to run factories
B. The crisis of alternative energy sources becomes more severe
C. Energy from the sun seems to be potentially the best alternative
D. Coal is considered not suitable to replace oil
E. Private industries have succeeded in producing energy from ocean wave and tides.

Often people who hold higher positions in # given group overestimate their performance,
while people in the lower levels of the group underestimate theirs. While this may not always be
true, it does indicate that often the actual position in the group has much, to do with the feeling
of personal confidence a person may have; Thus, members who hold high positions in a group or
feel that they have an important part to play in the group will probably have more confidence in
their own performance.

In almost all developing countries, the lack of adequate supplies of cheap, convenient and
reliable fuel is a major problem. Rural communities depend" largely on kerosene, wood and
dung for their cooking and lighting needs. But kerosene is now priced out of reach of any people
and wood, except in heavily forested areas, is in short supply. The search for firewood occupies
a large part of the working day and has resulted in widespread deforestation.
Dung is in constant supply wherever there are farm animals and, when dried, it is
convenient to store and use. But burning dung destroys its value as fertilizer, thus depriving the
soil of a much needed source of humus and nitrogen.
Rural areas of developing countries are also plagued by a lack of adequate sanitation.
Improper waste disposal spreads disease, contaminates water sources and provides breeding
grounds for disease-carrying insects.
The problems of improving environmental hygiene, conserving resources, and finding
alternative sources of fuel, may be unrelated. Their solutions, however, are not, as many
countries experimenting with biogas technology are discovering. Biogas, a mixture of methane
and carbon dioxide, is produced by the fermentation of organic matter. The process of
anaerobic fermentation is a natural one, occurring whenever living matter decomposes. By
keeping the matter - and the process - in a digester of biogas plant, the combustible gas can be
trapped and used as fuel for household lighting and cooking. The digested slurry that remains
can be used on the land as a soil conditioner arid fertilizer.
25. What are the two main problems mentioned in the text?
A. Pollution and the high price of fuel
B. Widespread deforestation and the use of dung
C. The lack of adequate fuel and. hygienic conditions
D. The lack of humus and nitrogen in the soil

C. The effect of burning dung on the soil
D. Biogas as a solution to many problems
E. The disadvantages of using dung as fuel
27. The disadvantage of traditional fuels used in developing countries is the they ....
A. reduce people's energy
B. are difficult to extract
C. C, make the soil poor
D. D, do not meet people needs
E. cause damage to the environment
28. The main factor causing the lack of adequate sanitation is ....
A. the domestic use of biogas
B. the great number of far animals
C. the pollution of water sources
D. the badly-managed waste disposal
E. the increase of disease-carrying insects
29. Why is the digested slurry of the fermented organic matter considered valuable?
A. It improves the quality of the soil for agriculture.
B. It increases the export from developing countries.
C. U is considered a relatively cheap fertilizer.
D. it is the best fertilizer in the world.
E. It can be used as fuel for cooking.

Hurricanes generally occur in the North Atlantic from may through November, with the peak
of the hurricane season in September; only rarely will they occur from December through April
in that part of the ocean. The main reason for the occurrence of hurricanes during this period is
that the temperature on the water's surface is at its warmest and the humidity of the air is at its
highest.
Of the tropical storms that occur each year in the North Atlantic only about five, on the
average, are powerful enough to be called hurricanes, To be classified as a hurricane, a tropical
storm must have winds reaching speeds of at least 117 kilometers per hour, but the winds are
often much stronger than that; the winds of intense hurricanes can easily surpass 240
kilometers per hour.

There are three separate sources of hazard in the process of supplying energy by nuclear
power. The radioactive material must travel from its place of manufacture at the power station.
Although the power stations themselves are solidly built, the containers used for the transport
of the materials are not. There are normally only two methods of transport available, namely
road or rail. Unfortunately, both of these involve close contact with the general public, since the
routes are sure to pass near, or even through, heavily populated areas.
Next, there is the problem of waste. All nuclear power stations produce wastes that in most
cases will remain radioactive for thousands of years. It is impossible to make these wastes non
radioactive, and so they must be stored in one of the inconvenient ways that scientists have in
vented. For example they may be buried under the ground, or dropped into abandoned mines,
or sunk in the sea. However, these methods do not solve the problem, since an earthquake
could easily crack the containers open.
Finally, there is the problem of accidental exposure due to a leak or an explosion at the
power station. As with the other two hazards, this is not every likely, so it does not provide a
serious objection to the nuclear program. Nevertheless, it can happen.
Separately, these there types of risks are not a great cause for concern. On the whole
though, the probability of disaster is still high.

who climb a mountain by the most dangerous route. Entrepreneurial types need to try out new
things without knowing whether they will succeed o fail. They also want to prove that they can
make it without big company support.
As well as motivation, most successful entrepreneurs have a number of personal

Cameroon is a West African country often million people which has been very successful in
growing food for it people, unlike many other West African countries. Since 1971 it has doubled
its output of major foodstuffs such a maize and potatoes. Now it is one of the few African
countries able to feed itself. This was not the case five years ago when the country was only 75-
80% self-sufficient in food. Although isolated pockets of hunger still remain, the World Bank
nowadays gives Cameroon money to sustain, not to achieve, self-sufficiency in food production.

Continued progress in advanced technology is not necessary. Already the technical progress
in our world ha caused severe pollution in the air and in the water. Although the technical
progress in previous years has been helpful recent technology has significantly increased
pollution. Another reason to stop technical progress is that many inventions which were
developed for good causes are now also used for powerful weapons or have been found to have
serious side effects. For example, pesticide put inside particle boards to prevent termites has
now been found to be toxic to human life. Technology does not always bring good effects; for
example, computers do much work faster than man. but then man loses his job to a machine.
Because no man can guarantee that technology will have only good effects and will be used only
for the benefit of man, we should delay the continued development of technology.

Magazine production involves teamwork. This means that many people have to work together to
produce the magazine you have in your hand. But one key person is the magazine editor. If some
one has a manuscript he wants to publish, he will send or submit it to the editor of the magazine he
likes. The magazine editor, usually the editor-in-chief, will read it and make recommendation so that
the manuscript can be published. Another task of a magazine editor is to consider whether the
article will be part of series. Will it have photographs or illustration? will it be in full color, two or
three colors, or black and white? Once the decision is made, the work of an illustrator or
photographer begins. Preparing manuscripts for the magazine is hard work to do. After everything is
all right, they are sent to the typesetters. When the galleys (or typeset text) come back, they must be
carefully read. This is the job of a proofreader to find out whether or not there are mistakes in
typesetting. Corrections are made if there are mistakes.
