Dear Sir/ Madam ,
I am writing in the hope that you can help me with a problem regarding a camera that I have bought recently.
On 24 April, I purchased a Canon digital SLR camera from a duty -free shop at Freetown Airport on my way from Freetown to
Wondercity. The camera cost $599, and I paid for it by credit card.
When I arrived at my hotel in Wondercity almost 24 hours later , I discovered that the box which contained the camera did not
include the battery , and the space in the box for the charger was empty.
I am now in Wondercity, and I am not returning to Freetown, so I need to get the missing parts here . I would be grateful if you
could arrange for the parts to be sent to me. I attach a copy of the receipt for your information.
I look forward to hearing from you.
Yours faithfully,
Introduction
This report looks at the dietary habits of twenty students in their final year at Freedonian Secondary School. The report is based
on the students’ responses to the questionnaire administered by the school’s doctor.
Meals
The survey have revealed that the students do not have enough meals. Only eight of those questioned eat before school, and half of
them have their midday meal at school. Worryingly, as few as four students have both breakfast and school lunch. Still more
disturbing is the fact that an alarming proportion— approximately onethird—of the students have neither.
Eating brown bread
Interestingly enough, bread, a good source of fiber, enjoys popularity among young people. 75 per cent of the students surveyed
eat three or more slices of brown bread per day, with only a quarter of respondents restricting themselves to one or two slices.
Eating fat
As regards fat consumption , the majority of the students eat margarine . Four students prefer butter, and another four eat neither.
Conclusion
It is noticeable that the eating habits of students in their final year at Freedonian Secondary School are not very healthy.
Moreover , there are no students who have both breakfast and school lunch, eat more than four slices of brown bread per day, and
avoid fat.
In this essay, I will discuss whether prevention is better than trying to treat people who are ill and whether or not this is possible in
all cases . I will divide the subject into illnesses caused by lifestyle, and illnesses caused by other factors such as genetic factors.
First of all, a person ’s lifestyle can be a major factor in their wellbeing, both physical and mental . People who eat too much
fast, fatty, or sugary foods without doing enough physical activity , may put on weight . This has serious effects and can lead to
heart disease . Similarly, people who smoke and drink too much run the risk of getting cancers and heart disease. However , by
avoiding these things and doing simple things such as walking short distances instead of driving , eating five portions of fresh fruit
and vegetables a day, and taking 20 minutes’ exercise three times a week reduces this risk and can prevent disease.
As regards genetic factors, the situation is not so clear . Certain genetic factors mean that some people are forced into a
lifestyle. For example, people who have certain allergies have to avoid foods containing the things they react badly to. In this case,
avoiding certain foods as prevention is obviously necessary. Other more serious genetic diseases , for instance neuropathies,
spinocerebellar degenerations, and certain metabolic disorders , cannot be treated by prevention and need to be treated medically.
In conclusion, although many illnesses are preventable, in some cases, however, it may already be too late for any prevention
efforts; and the money could be spent on research and on developing cures for people with chronic disorders.

Since the beginning of human life, enormous changes around us have taken us to a path of scientific progress, which in turn has
benefited mankind in a number of ways. In every era, man has innovated many things in order to cater for his rising needs .
Undoubtedly, the emergence of necessities has always led man to creative exploration.
As time passed, primitive man realized other needs arising around him. After catering to his fundamental needs of food and
shelter, man felt the need for acquiring goods which he could not produce himself . This led to the idea of the barter system under
which goods were exchanged without the use of money, but a constraint to this mechanism was his limited movement. How far
could a man travel , loaded with tons of wheat just for the sake of some kilos of meat? Then, man came up with the idea of the
wheel .
Furthermore, as communication was channelized, rising horizons of the world led to the imperative need to express oneself.
As the need arose, man seized the use of pictures and paintings for self-expression, which later developed the concept of writing.
With the need for writing evolved the need for a substance to write on. Rocks, parchments, and leaves were initially used, but they
were not satisfactory. With the passage of time, paper was first invented in China and later mushroomed in the rest of the world.
The above inventions were worth mentioning to interpret the fact that how man moulded himself in accordance with his needs.
As the need arose, man came up with new ideas , new thoughts, and forcefully pushed his mind to run on that particular line of
action. Even in the modern era, man has been found to observe the same behavioral patterns . Some years ago, TB and cancer
were regarded as incurable diseases, man conducted massive research on them and finally came up with effective solutions .
Whether it is the old age or modern era, man has been found too efficient to satisfy his needs and has set numerous examples
of it. No matter whether it was a political issue, scientific concern, or even day-to-day chores of life man has reacted in a flexible
mood to create a way for himself whenever he realized his needs. Unsurprisingly, he has been successful in achieving an
alternative source for his need each time as wherever there is a will, there is a way.

The debate about the best way to generate electricity is back on the agenda. The most common methods are by burning coal ,
building dams, or using nuclear power .
However, many people think that nuclear power is dangerous , and when you consider the experience of Chernobyl in the
Ukraine over 20 years ago, you can see why. Countries such as France , however, get about 80% of their electricity from nuclear
power plants , and the pro-nuclear scientists argue that it is actually much clearer than burning fossil fuels , which contributes to
global warming .
Others argue that it is better to get electricity from sustainable resources, such as the wind, the sea, and the sun. Although this
sounds like a sensible idea, they are not reliable enough to malntain a constant supply of power. For instance, you cannot produce
solar energy at night .
Basically, we need a source of energy that will not run out; if it cannot be hydroelectricity or coal-fired energy, it will have to
be nuclear. Finding a way of ensuring that nuclear power is safe and cannot be misused is the real challenge.

The surface of the Earth seems to be warming as a result of the greenhouse effect, created by a build-up of harmful gases in the
atmosphere. Greenhouse gases can occur naturally; however, human activity add to the levels of these gases, causing more
problems. Scientists estimate that the average air temperature could climb a few degrees Celsius in twenty years. Global warming
will affect humans , animals, and even plants.
Obviously, our ‘precious home’ is undergoing dramatic alterations in weather patterns, leading to significant changes in the
world’s physical environment. Sea temperatures and levels are projected to rise due to the melting of the polar ice caps and
thawing of permafrost, which represents an insidious threat to coastal communities throughout the world. Several diverse extreme
weather events, such as droughts, floods , and hurricanes, are occurring concurrently around the world, giving rise to an
unprecedented loss of human life and property. Increases in the frequency and intensity of heat waves and precipitation have also
been observed .
Consequently, a growing number of exotic animals are now on the verge of extinction. More disappointingly, the above-
mentioned climatic changes, combined with heedless deforestation and noxious industrial emissions will not only affect animal life
by changing important habitats but will also contribute to soil erosion and leaching. Thus, crop yields are expected to continue to
drop in coming decades, resulting in widespread famine. Moreover, many regions will face dwindling water supplies as the result
of shrinking glaciers and snowpack, evaporation, and the infiltration of salt water. Acute food and water shortages will
presumably bring about manifold health problems.
To summarise the situation, having no visible manifestation, global warming has been affecting the earth for quite a while
now; the effects of climate change , while not immediate, are potentially catastrophic. I would describe global warming as ‘an
environmental time bomb ticking away .’

Personal freedom is a concept the meaning of which depends on the context from which it arises and to which it applies. In other
words, it is a concept without a fixed meaning.
To most people, freedom means the absence of fetters or bondage, eg. having the power to act or to speak or to think without
externally imposed restraints. One’s childhood’s dream of adulthood is the desire to be independent. One’s adulthood's dream of
childhood is the desire to be free from responsibility and enjoy a life without care. In each case, the dream of freedom is idealised.
A child dreaming of being an adult wants the independence that the adult has but does not understand the responsibility that
accompanies it. An adult dreaming of being a child wants the carefree life that the child has but does not remember that a child is
incapable of doing things that most adults take for granted . The only difference between an adult contentedly remembering
childhood and an adult desperately reliving childhood is that one has learned to live within the restrictions of adulthood while the
other keeps trying to overcome them. What an illusion !
Another ‘ bitter ’ illusion. Some people believe that they are in control of their lives . They like the idea that they are the masters
of their destiny and take personal responsibility for what happens in their lives. However, considering that everything in the
universe is interconnected and in the process of constant change, how can one believe in freedom of choice ? Indeed, people are
presented with some choices; but for different reasons, these choices are limited by somebody or something . One can choose one’s
profession, one’s friends , one’s interests, one’s city of residence; however, having chosen to be an engineer, for example, one
cannot refuse to learn calculus.
In conclusion, ours is not a world where nobody dominates another or is influenced by anything , by violence, by monetary
power, by property rights, by social weight, or by any other means. Hence , it is impossible to find a freedom in which there are no
limits , which means that there is no such thing as absolute freedom, and people just delude themselves into believing that they are
‘free individuals’.
