Mining tourism in Ouro Preto
Ouro Preto is surrounded by a rich and varied natural environment with waterfalls, hiking trails and native vegetation partially protected as state parks. Parts of these resources are used for tourism. Paradoxically, this ecosystem contrasts with the human occupation of the region that produced, after centuries, a rich history and a cultural connection to mining, its oldest economic activity which triggered occupation. The region has an unlimited potential for tourism, especially in specific segments such as mining heritage tourism, in association or not with the existing ecotourism market. In fact, in Ouro Preto, tourism, history, geology and mining are often hard to distinguish; such is the inter-relationship between these segments.
For centuries, a major problem of mining has been the reuse of the affected areas. Modern mining projects proposed solutions to this problem right from the initial stages of operation, which did not happen until recently. As a result, most quarries and other old mining areas that do not have an appropriate destination represent serious environmental problems. Mining tourism utilizing exhausted mines is a source of employment and income. Tourism activities may even contribute to the recovery of degraded areas in various ways, such as reforestation for leisure purposes, or their transformation into history museums where aspects of local mining are interpreted.
Minas Gerais, and particularly Ouro Preto, provides the strong and rich cultural and historical content needed for the transformation of mining remnants into attractive tourism products, especially when combined with the existing cultural tourism of the region. Although mining tourism is explored in various parts of the world in extremely different social, economic, cultural and natural contexts, in Brazil it is still not a strategy readily adopted as an alternative for areas affected by mining activities.

Acid rain and… the facts
www.acidrain.org.ca / Oxford Children´s Encyclopedia
What causes acid rain?
Acid rain is caused by air pollution. When fossil fuels such as coal and oil are burned, two gases, sulphur dioxide and nitrogen oxide, are released into the atmosphere. These two pollutants eventually react with the moisture in the air. When this polluted mixture falls onto the ground, it is called acid rain.
Rain measuring between 0 and 5 on the pH scale, is acidic therefore called ACID RAIN.
Acid rain is harmful to the environment. It is hard to control because it may be blown by the wind, falling thousands of kilometers from where it was first formed. For example, much of the acid rain in Canada is caused by smoke from factories and power-stations in the USA. The acid rain in Scandinavia may come from Britain.
What are the effects of acid rain?
Acid rain has many different effects. It has killed fish in the lakes of North America, Scandinavia, Scotland, and Wales. Vast areas of forest in northern and central Europe are dying because of it, while in many European cities statues and stone buildings are being eaten away by the acid. Acid rain corrodes metalwork such as steel bridges and railings; it also attacks some types of concrete. Even the water that we drink is slowly being polluted by acid rain.
What are the effects on trees and soil?
One of the most serious impacts of acid precipitation is on forests and soils. Great damage is done when sulphuric acid falls onto the earth as rain. Nutrients present in the soils are washed away. Aluminium also present in the soils is freed and this toxic element can be absorbed by the roots of trees. Thus, the trees starve to death because they have been deprived of their vital nutrients such as calcium and magnesium.
Acid rain is one of the most serious environmental problems of our time. It is a global problems that is gradually affecting our world.
How does acid rain effect lakes?
Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, various types of fish disappear. Other effects of acidified lakes on fish include: decreased growth, inability to regulate their own body chemistry, reduced egg deposition, deformities in young fish and increased susceptibility to naturally occurring diseases.
Clean rain usually has a pH of 5.6. It is slightly acidic because of carbon dioxide which is naturally present in the atmosphere. Vinegar, by comparison, is very acidic and has a pH of 3.
What is pH?
This is a measure of how acidic or alkaline a substance is. (See a pH scale below).
The initials pH stand for Potential of Hydrogen. Acids have pH values under 7, and alkalis have pH values over 7. If a substance has a pH value of 7. It is neutral-neither acidic or alkaline.
Because the pH scale is logarithmic, a difference of one pH unit represents a tenfold, or ten times change. For example, the acidity of a sample with a pH of 5 is ten times greater than that of a sample with a pH of 6. A difference of 2 units, from 6 to 4, would mean that the acidity in one hundred times greater, and so on.

Acid rain corrodes metalwork such as steel bridges and railings; it also attacks some types of concrete. Even the water that we drink is slowly being polluted by acid rain.
What are the effects on trees and soil?
One of the most serious impacts of acid precipitation is on forests and soils. Great damage is done when sulphuric acid falls onto the earth as rain. Nutrients present in the soils are washed away. Aluminium also present in the soils is freed and this toxic element can be absorbed by the roots of trees. Thus, the trees starve to death because they have been deprived of their vital nutrients such as calcium and magnesium.
Acid rain is one of the most serious environmental problems of our time. It is a global problems that is gradually affecting our world.
How does acid rain effect lakes?
Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, various types of fish disappear. Other effects of acidified lakes on fish include: decreased growth, inability to regulate their own body chemistry, reduced egg deposition, deformities in young fish and increased susceptibility to naturally occurring diseases.
Clean rain usually has a pH of 5.6. It is slightly acidic because of carbon dioxide which is naturally present in the atmosphere. Vinegar, by comparison, is very acidic and has a pH of 3.
What is pH?
This is a measure of how acidic or alkaline a substance is. (See a pH scale below).
The initials pH stand for Potential of Hydrogen. Acids have pH values under 7, and alkalis have pH values over 7. If a substance has a pH value of 7. It is neutral-neither acidic or alkaline.
Because the pH scale is logarithmic, a difference of one pH unit represents a tenfold, or ten times change. For example, the acidity of a sample with a pH of 5 is ten times greater than that of a sample with a pH of 6. A difference of 2 units, from 6 to 4, would mean that the acidity in one hundred times greater, and so on.

Acid rain and… the facts
www.acidrain.org.ca / Oxford Children´s Encyclopedia
What causes acid rain?
Acid rain is caused by air pollution. When fossil fuels such as coal and oil are burned, two gases, sulphur dioxide and nitrogen oxide, are released into the atmosphere. These two pollutants eventually react with the moisture in the air. When this polluted mixture falls onto the ground, it is called acid rain.
Rain measuring between 0 and 5 on the pH scale, is acidic therefore called ACID RAIN.
Acid rain is harmful to the environment. It is hard to control because it may be blown by the wind, falling thousands of kilometers from where it was first formed. For example, much of the acid rain in Canada is caused by smoke from factories and power-stations in the USA. The acid rain in Scandinavia may come from Britain.

Building a Practical College Degree for the
New Economy
This is not a great time to be a recent college graduate.
Average student-loan debt is $29,400. The underemployment rate is 44 percent for graduates ages 22 to 27, meaning they are holding jobs that don’t require bachelor’s degrees. And the average age of financial independence for college graduate these days is 30.
Such statistics have given rise to the narrative that a college degree is no longer worth it, although volumes of economic studies on lifetime earnings prove otherwise. Even so, given the number of college graduates struggling to launch their careers, a wide gap has emerged between what the workforce needs in employees and what colleges are producing in graduates.
Part of the problem is that we have high expectations for the bachelor’s degree today. Thirty years ago, when fewer people required a higher education to get ahead in life, the bachelor’s degree was seen as a vehicle for broad learning. The training part came later by going to graduate school or getting a job where the new employer trained you.
Now we demand that skills training move in tandem with broad learning, and expect both to be completed in the four years of an undergraduate education. For too many students, however, the bachelor’s degree is not providing that dual experience – high-impact, in-classroom learning and out-of-theclassroom, experiential, and hands-on learning necessary for success in today’s economy.
Because of student loan debt, graduate or professional school is no longer an option for many recent college graduates. They’re searching for quick and cheap addon boot camps that give them what they’re missing. And a whole new set of providers are emerging outside of the traditional higher-education ecosystem to provide that lift.
Last year, General Assembly, which offers courses of a few hours to a few weeks in everything from digital marketing to web development, expanded to Washington, DC, where it is selling out of nearly all of its offerings. Its average student is in his mid-20s and just a few years out of college.
Choose the alternative that could correctly and respectively substitute the words in bold from the text.
Choose the alternative that rewrites correctly the excerpt below, taken from the text “Cat Watch 2014: What’s it like being a cat?” published by the BBC News, using the past simple.
Cats are at a crucial point in their evolutionary journey as they transform from solitary hunters to domestic pets, a study by the BBC and the Royal Veterinary College has revealed.
Cats’ highly-developed senses, honed through millions of years of evolution, make them highly efficient predators. In fact, our pets interact with the world in a very different way to us.
Cats see the world in muted colours, making it easier for them to see movement without distractions. They also have large eyes for their size, allowing them to see well in low-level light.
However, they can’t focus on anything less than a foot away, so use their whiskers for detecting objects closer to their bodies.
Read the paragraphs below and choose the alternative that fills in correctly and respectively the blanks with the comparative of equality, the comparative of superiority or the superlative of the given adjectives in parentheses.
This is how stars die
5,000 light years away in Centaurus, a large constellation in the southern sky, is the Boomerang Nebula, a cloud of gas being expelled from a dying star.
This cloud is one of _________ (bizarre)1 and ___________ (mysterious)2 objects in the universe. Here, within the gas streaming outwards, astronomers have found that the temperature drops ___________ (low)3 nearly absolute zero.
It is, ___________ (far)4 anyone knows, the coldest place in the universe.
It may also prove to be quite important. Because this ____________ (frigid)5 place, and objects like it, albeit a tad ___________ (warm)6 – may help astronomers unravel a host of cosmic conundrums, from the violent yet spectacular deaths of stars and the formation of galaxies to cosmic explosions and the origin of life itself.
Death of stars, birth of life
In many respects the Boomerang Nebula is unremarkable. All stars have to die some day. When ___________ (small)7 stars end, those about eight times _____________ (massive)8 our own sun, they produce a similar display of gas and dust.
