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)
Observe as sentenças a seguir:
I - For now on you have your own bedroom.
II - My father was a bus driver for 10 years.
III - My mother-in-law is very sweet.
Assinale a alternativa correta:
Text 18A3-I
The roar of a waterfall suggests the power of water. Rampaging floodwaters can uproot strong trees and twist railroad tracks. When the power of water is harnessed, however, it can do useful work for humans.
Since ancient times, people have put the energy in the flow of water to work. They first made water work for them with the waterwheel, a wheel with paddles around its rim. Flowing water rotated the waterwheel, which in turn ran machinery that was linked to it. Today, new kinds of waterwheels — turbines — spin generators that produce electricity. Electricity from water-turned generators is known as hydroelectricity.
By building a dam across a river, the natural upstream water level is elevated and a difference in head is created that can be used to drive turbines and generate electricity. A large upstream reservoir may balance seasonal water flow; rain or melted snow can be stored in the reservoir during the wet season to provide electricity during dry seasons.
Waterpower is distributed unevenly among the continents and nations of the world. Europe and North America have developed much of their waterpower. Asia, South America, and Africa have abundant waterpower potential, but while countries such as China and Brazil have become leading hydroelectric producers, much of the waterpower resource on those continents remains undeveloped.
