Water and oil don’t mix. We see this every day; just try washing olive oil off your hands without soap or washing your face in the morning with only water. It just doesn’t work!
When an oil spill occurs in the ocean, like the catastrophe in the Gulf of Mexico, what do scientists do to clean up the toxic mess? There are a number of options for an oil spill cleanup and most efforts use a combination of many techniques. The fact that oil and water don’t mix is a blessing and a curse. If oil mixed with water, it would be difficult to divide the two.
Crude oil is less dense than water; it spreads out to make a very thin layer (about one millimetre thick) that floats on top of the water. This is good because we can tell what is water and what is oil. It is also bad, because it means the oil can spread really quickly and cover a very large area, which becomes difficult to manage. Combined with wind, ocean currents and waves, oil spill cleanup starts to get really tricky.
Chemical dispersants can be used to break up big oil slicks into small oil droplets. They work like soaps by emulsifying the hydrophobic (waterrepelling) oil in the water. These small droplets can degrade in the ecosystem quicker than the big oil slick. But unfortunately, this means that marine life of all sizes ingest these toxic, broken-down particles and chemicals.
If the oil is thick enough, it could be set fire, a process called “in situ burning”. Because the oil is highly flammable and floats on top of the water, it is very easy to set it alight. It’s not environmentallyfriendly though; the combustion of oil releases thick smoke that contains greenhouse gases and other dangerous air pollutants.
Some techniques can contain and recapture spilled oil without changing its chemical composition. Booms float on top of the water and act as barriers to the movement of oil. Once the oil is controlled, it can be gathered using sorbents. “Sorbent” is a fancy word for sponge. These sponges absorb the oil and allow it to be collected by siphoning it off the water.
However, weather and sea conditions can prevent and obstruct the use of booms, sorbents and in situ burning. Imagine trying to perform these operations on the open sea with wind, waves and water currents moving the oil (and your boat!) around on the water.
What about the plants and animals? It’s easy to forget about the organisms in the sea that are under water. Out of sight, out of mind! There is not much we can do to help them. But when oil reaches the shore it impacts sensitive coastal environments including the many fish, bird, amphibian, reptilian, and crustaceanspecies that live there. We have easy access to these areas and there are some things we can do to clean up. For the plants, it is often a matter of setting them on fire, or leaving them to degrade the oil naturally. Sometimes, we can spray the oil with nutrients (phosphorus and nitrogen) that can encourage the growth of specialized microorganisms. For species that can tolerate our soaps, manpower is needed to wash every affected animal. Yet, if the animal has tried to lick itself clean, it can die from ingesting the toxic oil.
Unfortunately, there can be many negative economic and social impacts, in addition to the environmental impacts of oil spills and, as you’ve just read, the clean up techniques are far from perfect. Prevention is the very best cleanup technique we have. http://www.curiocity.ca/everyday-science/environme... -cleaning-up-a-spill.html, retrieved on Dec 10, 2010

A música “Hunting High and Low” foi um dos grandes sucessos da banda norueguesa A-ha na década de 80. Leia a letra da canção e responda a questão.
Hunting High and low
(Paul Waaktaar-Savoy)
Here I am
And within the reach of my hands
She sounds asleep
And she's sweeter now
Than my wildest dream
Could have seen her.
And I watch her sleeping away
But I know I'll be
Hunting high and low
Ah, there's no end
To the lengths I'll go to
Find her again
Upon this my dreams are depending
Through the dark
I sense the pounding of her heart
Next to mine
She's the sweetest love
I could find
So I guess I'll be
Hunting high and low
Do you know what it means
To love you
I'm hunting high and low
And now she's telling me
She's got to go away
I'll always be hunting high and low
Only for you
Watch me tearing myself to pieces,
Oh, for you I'll be hunting high and low

TEXT 2
I do realize that in the world of technology there are early and late adopters. I’m not the earliest of cutting-edge early TESL adopters, but I do like to try out new technology and incorporate it into my teaching. This list is a handful of technologies that are established enough not to be too problematic, user-friendly enough that just about anyone can start using them quickly, and useful enough that you’ll soon wonder how you got along without them. In short, this is a list of tech that just about everyone can (and maybe even should) be using in 2010.
1. Wikipedia – It has become popular to question its accuracy. Wikipedia has become a real knowledge bank on the internet. Once we figure out what it is (a compilation of all referenced knowledge) many of these criticisms fall down. Access to all this information means a reorganization of learning.
2. Google – No, I don’t just mean search, but all the other stuff: maps, docs, calendar, etc. It’s never been so easy to collaborate with other people.
3. Twitter – A year ago, I taught a course through Twitter with mixed results. This microblog is almost exclusively interactive, but my ESL students found it tough to collaborate within Twitter because of its constraints on length. The email by contrast, is very simple – it is equally interactive but it is constraint free. So, you should use it and you should see interesting results !
Can you learn the language by using the above alone? Of course not! But they are a good springboard and I hope they lead you to discover all other media available out there (ebooks, blogs, YouTube videos, music, movies, etc.).
More web in the pipeline. Please post a comment.

TEXT 1
At least 200 people have died in the Brazilian state of Rio de Janeiro after another storm. This is arguably the worst torrential rain for decades, causing flooding and landslides. Our website readers in Rio de Janeiro have been sharing their experiences.
Comment 1 - I’ve never seen such chaos. We weren’t prepared for this, even though we were warned that a big storm was about to come. Newspapers are saying that the reason for the catastrophe is the garbage. Well it may have been. We need to teach recycling at schools and community groups, otherwise we will have more disasters like this. (Lia, Niterói)
Comment 2 - Today I witnessed Rio de Janeiro on the brink of collapse. I ventured out around midday, just as the electric power blacked out in my neighbourhood. Three hours later, looking out of my office window, the city still reminded me of a war zone. “What´ve we done to deserve this?”, I thought. It’s night time now and I haven’t been able to return home. I might do so tomorrow. (José, Rio)
Comment 3 - Worldwide, we are seeing more and more
climate instability. The deserts of central Asia are growing,
while areas of the US (and now Rio) are drenched. The lakes
in Minnesota have never thawed this early, at any time in the
recorded record. The icecaps will be history, and islands
around the world are disappearing under the surf. The oceans
are warming, the coral reefs are dying. How much more
evidence do we need of global warming? (João, Brasília)
