Pollution Thick black smoke curling out of smokestacks, horrible-tasting chemicals in your drinking water, pesticides in your food - these are examples of pollution. Pollution is any contamination of the environment which causes harm to the environment or the inhabitants of the environment. There are many kinds of pollution, and there are many pollutants. Some obvious kinds of pollution are pollution of the air, soil, and water. Some less obvious, or less salient kinds of pollution are radioactive, noise, light pollution, and green-house gasses. Air pollution can be caused by particles, liquids, or gases that make the air harmful to breathe. There are two main types of air pollution: primary and secondary. Primary pollutants enter the air directly, like smoke from factories and car exhaust. Secondary pollutants are chemicals that mix together to pollute the air, like mixtures of emissions, or waste output, from vehicles and factory smoke that change to form more dangerous pollutants in the air and sunlight. Soil pollution can be caused by pesticides, leakage..........................chemical tanks, oil spills, and other chemicals..........................get into the soil by dumping or accidental contamination. Soil pollution can also cause water pollution.............................underground water becomes contaminated by coming.............................contact with the polluted soil. Water pollution can be caused by waste products, sewage, oil spills, and litter in streams, rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of death and disease in the world, causing about 14,000 deaths in the world each day. Radioactive pollution can be caused by leaks or spills of radioactive materials. These materials can come from medical sources, nuclear power plants, or laboratories which handle radioactive materials. Air, soil, and water can be polluted by radioactivity. It can cause damage to animals, both internally and externally, by eating, drinking, or touching it. It can cause birth defects and genetic problems. It can cause certain cancers and other deadly diseases. Noise pollution can be caused by vehicle, aircraft, and industrial noise. It can also be caused by military or experimental sonar. Noise has health effects on people and animals. In people, it can cause high blood pressure, heart problems, sleep disturbances, and hearing problems. In animals, it can cause communication, reproductive, and navigation problems – they have difficulty finding their direction. Sonar has even caused whales to beach themselves because they respond to the sonar as if it were another whale. Light pollution can be caused by advertising signs, stadium and city lighting, and other artificial lighting (like the light caused by night traffic). Artificial lighting has health effects on humans and animals. In people, it can cause high blood pressure and affect sleeping and waking rhythms and immunity. It might be a factor in some cancers, such as breast cancer. In animals, it can affect sleeping and waking rhythms, navigation, and reproduction. In addition, greenhouse gases have caused a warming effect on the earth’s climate. The greenhouse gases are water vapor, carbon dioxide, methane, and ozone. They are naturally–occurring gases in the atmosphere, but human activity has increased their concentration in the atmosphere. For example, the levels of carbon dioxide (CO2) in the atmosphere have risen due to the burning of fossil fuels. The effect is a rise in global temperatures. The higher temperatures cause the melting of glaciers, a rise in the water level of oceans, and the disruption of both land and marine life, including that of humans. Although carbon dioxide is necessary for plants to survive, it is also considered to be a kind of pollution because high levels of carbon dioxide have caused the oceans to become more acidic. It is not possible for anyone to predict the exact timing and effects of global pollution and global climate change brought about by pollution. There is general agreement by scientists that the global climate will continue to change, that the intensity of weather effects will continue to increase, and that some species of animals will become extinct. There is also general agreement, or consensus, that humans need to take steps to reduce emissions of waste products and greenhouse gases into the atmosphere, make adaptations to the changes that are occurring, and figure out ways of reversing the trends of pollution and global warming.

The route to perfection

1 _____ Can there be perfection without pain for those who
are successful in the world of dance? Achieving excellence
depends on many different things, including physique and
4 luck. However, it is indisputable that those who dance
professionally must also follow a rigorous training regime.
Like athletes, dancers have to be strong, but they
7 also have to combine fitness with elegance and musicality.
It is said that giving a professional dance performance is not
dissimilar to playing a football game as dancers have to
10 alternate periods of sustained activity with short bursts of
explosive energy, and also being able to recover quickly.
It is worth noting that while in the past dancers used
13 to train mostly by going through repetitive routines, with
the high fitness standards that are currently the norm, they
use additional new techniques such as gym routines in order
16 to gain muscle strength and stamina. This will perhaps help
them attain their ultimate goal: perfection.

Sound Advice for Language Learners

1 A recent issue of a language learning magazine has
consulted a number of experts in the field of second
language acquisition. Their advice may prove invaluable for
4 those considering a language course. Ask yourself some
basic questions, they suggest. Did you enjoy studying
languages at school, for example? Can you really afford the
7 time to learn a language?
First and foremost, you have to be realistic in your
goals. If you fail to set achievable aims you are likely to give
10 up. Besides, it is worth knowing that the most expensive
courses are not necessarily the best. You should also bear in
mind that the quicker you learn a language the more quickly
13 you forget it. Sue Miller, a French teacher, attempted to
teach herself German by enrolling on a crash course.
Already fluent in three languages, her chances of making
16 progress were high. Two years on she hardly remembers
anything. “I should have chosen a regular course in order to
have more time for practice and consolidation.”
19 Sue’s comment is certainly a good piece of advice.

A Musical Genius

1 Beethoven is one of the most influential figures in
the history of classical music. His exceptional talent was
already evident when he was still a young man, trying to
4 survive a rather unorthodox upbringing. Indeed, his
eccentric father would often make him study music in the
middle of the night.
7 Soon, the young Beethoven's ability won him the
admiration of the leading contemporary musical figures.
However, just at the point when he was beginning to reap
10 the rewards of his early endeavors, he realized that he was
becoming deaf. Beethoven felt devastated as it was clear to
him that his increasing deafness was incurable. And yet, he
13 kept composing and his music displayed a striking change in
style, becoming both heavier in tone and larger in scale.
