Aulas de Inglês

Que tal aprender ou desenvolver a fluência em inglês e, simultaneamente, conhecer algumas das obras literárias mais famosas da Literatura Inglesa? O curso oferece o desenvolvimento das habilidades de fala, escrita, compreensão oral e leitura em inglês, a partir da leitura de textos literários adaptados ao seu nível de conhecimento de inglês. Durante as aulas além de lermos e ouvirmos as histórias, comentamos e analisamos fatos, personagens e conhecemos o contexto sociocultural no qual as obras foram produzidas (tudo em inglês!).
Posso garantir que é aprender inglês de forma divertida, motivadora e interessante.
Se tem interesse entre em contato com Kaciana, pelo e-mail: kacianalonso@gmail.com e agende um horário para saber mais.  As vagas para início em Agosto/2012 já encontram-se abertas. Reserve seu horário.

Language, Power and Imperialism

The following text was part of the English Test of Usp Entrance Exam in 2004. It is about how language can be used as a weapon to exterminate another language, a culture and a people.

English is a colonial language that continued to be the official language after independence in virtually all African countries that were under British rule. In some cases it was retained to avoid ethnic tensions. But in all cases it was retained because of its prestige and association with power. In contrast, the vernaculars were viewed as backward and inferior, and so were not developed. Students were made to feel ashamed of their mother tongue and punished for speaking it. 
In Kenya, for example, speaking in vernacular was forbidden and sanctioned in schools. One popular method of punishment was to make pupils carry around a skull of some dead animal the whole day as a way of embarrassing the pupil who dared speak in his mother tongue. 

Today it is difficult to use indigenuous languages because they have not developed , been codified and standardised. Hence there is a shortage of teaching materials and trained teachers in the vernaculars. And this has often been used as an excuse for not adopting the vernaculars in schools.

Why do we yawn?

Yawning... And Why Yawns Are Contagious 

Before you read any more of this page, get a pencil (or pen) and paper.
I will wait...I'm still waiting...Did you get it? Good!
With your pencil and paper, keep track of the number of times you yawn while you are reading this page. I hope reading this page is not boring, but you may find that just thinking and reading about yawning makes you yawn. The results may surprise you. Did you yawn yet? If you did, make sure you count it.
Everyone yawns - babies, kids, teenagers, adults. Some birds, reptiles and most mammals also yawn. However, the reason why we yawn is a bit of a mystery. There is also very little research about yawning because for most people yawning is not a problem. Here are a few things that are known about yawns:
  1. The average duration of a yawn is about 6 seconds.
  2. In humans, the earliest occurrence of a yawn happens at about 11 weeks after conception - that's BEFORE the baby is born!
  3. Yawns become contagious to people between the first and second years of life.
  4. A part of the brain that plays an important role in yawning is the hypothalamus. Research has shown that some neurotransmitters (for example, dopamine, excitatory amino acids, nitric oxide) and neuropeptides increase yawning if injected into the hypothalamus of animals.
You know that when you are bored, you yawn. Scientists have confirmed this observation by comparing the number of yawns in 17-19 year old students who watched music videos to the number of yawns in students who watched an uninteresting color test bar pattern.
As you might have expected, people who watched the color test bar pattern yawned more (5.78 yawns in 30 minutes) than those who watched the "MTV-like" video (3.41 yawns in 30 minutes.) The average duration of yawns was also slightly longer in the test bar viewing group. One unexpected finding was that yawns in male students had a longer duration than those in female students.

Many people assume that we yawn because our bodies are trying to get rid of extra carbon dioxide and to take in more oxygen. This may make some sense. According to this theory, when people are bored or tired, they breathe more slowly. As breathing slows down, less oxygen makes it to the lungs. As carbon dioxide builds up in the blood, a message to the brain results in signals back to the lungs saying, "Take a deep breath," and a yawn is produced.
The only problem with the excess carbon dioxide theory is that research shows that it may not be true. In 1987, Dr. Robert Provine and his coworkers set up an experiment to test the theory that high carbon dioxide/low oxygen blood content causes yawning. Air is normally made up of 20.95% oxygen, 79.02% nitrogen, 0.03% carbon dioxide and a few other gases in low concentrations. The researchers gave college students the following gases to breathe for 30 minutes:
Gas #1 = 100% Oxygen
Gas #2 = 3% Carbon dioxide, 21% Oxygen
Gas #3 = 5% Carbon dioxide, 21% Oxygen
Gas #4 = Normal Air
Breathing 100% oxygen (Gas #1) or either carbon dioxide gas (Gas #2 and #3) did cause the students to breathe at a faster rate. However, neither carbon dixoide gas nor 100% oxygen caused the students to yawn more. These gases also did not change the duration of yawns when they occurred.
The researchers also looked for a relationship between breathing and yawning by having people exercise. Exercise, obviously, causes people to breathe faster. However, the number of yawns during exercise was not different from the number of yawns before or after exercise. Therefore, it appears that yawning is not due to CO2/O2 levels in the blood and that yawning and breathing are controlled by different mechanisms.

So, the question remains - why do we yawn? Dr. Provine suggests that perhaps yawning is like stretching. Yawning and stretching increase blood pressure and heart rate and also flex muscles and joints. Evidence that yawning and stretching may be related comes from the observation that if you try to stifle or prevent a yawn by clenching your jaws shut, the yawn is somewhat "unsatisfying." For some reason, the stretching of jaw and face muscles is necessary for a good yawn.
In 2007, researchers proposed that yawning is used to cool the brain. They found that people yawned more often they pressed a warm or room temperature towel against their heads than when they pressed a cold towel against their heads. People who breathed through their noses (thought to reduce brain temperature) did not yawn at all.
It is possible that yawns are contagious because at one time in evolutionary history, the yawn served to coordinate the social behavior of a group of animals. When one member of the group yawned to signal an event, all the other members of the group also yawned. Yawns may still be contagious these days because of a leftover response (a "vestigial" response) that is not used anymore. None of this has been proven true and yawns are still one of the mysteries of the mind.
So, how many times did you yawn?
Still interested in yawns? Try an experiment to keep track of your own yawning.
Did you know?
Here's a new vocabulary word for you: pandiculation. Pandiculation is the act of stretching and yawning.
They said it!
A yawn is quite catching you see. Like a cough.
It just takes one yawn to start other yawns off."
--- Dr. Seuss (in Dr. Seuss's Sleep Book, New York: Random House, 1962.)
