Brazilians tend not to find any particular language offensive. For their country is a melting pot of just about any culture and language in the world. Despite the universality of their own culture, Brazilians are used to tourists, and people throughout the world, not knowing Portuguese. They even are used to tourists, and people throughout the world, not knowing that there even is such a thing as the Portuguese language. So Brazilians tend not to find either the particular language or the particular language speaker offensive. Instead, what they find offensive is a particular attitude. For Brazilians love their country, their culture, their history, and their language. And they don't appreciate it when people disrespect the rights, and the enjoyment, of others.

Answer

Brazilians do not find a foreign language offensive, however they might not understand the language, specially if you speak russian, chinese, greek, arabic, Hindi, etc.

It isn't offensive to speak in any language so long as you try to speak Portuguese first, and ask if the person speaks your language. It is very offensive to have someone assume you speak English, but so long as you ask in Portuguese if they speak English (and they say yes) then it isn't offensive.

Brazilians do not find offensive if foreigners try to speak in another language. They might not understand what you mean, as the only language spoken in Brazil is Portuguese, however in big cities or touristy areas English and Spanish is also known.

Answer

Brazilians speak Portuguese. Brazil is the only western nation, the only Latin nation in the Americas where Portuguese is the national language. Due to the history and their culture, it is offensive to them when others assume they speak Spanish, much as it is offensive to those from other Latin cultures when someone speaks to them in a different dialect, i.e. Puerto Rican to a Cuban, Mexican to a Puerto Rican, Argentinian to a Mexican, etc.

Brazilians tend to be proud of their country's accomplishments, cultures and vast natural beauty. They also tend to know that one of the great beauties of their country is its role as a melting pot of cultures, geographies, histories and languages. And they also tend to realize that some tourists and visitors don't know that there even is such a thing as the Portuguese language.

So Brazilians tend to be respectful of the cultures and languages of other peoples. At the same time, they tend to welcome opportunities to share their diverse country with tourists and visitors. And so they tend not to find it offensive when people speak to them, be it in Brazilian Portuguese, the Portuguese of Portugal or of one of the former Portuguese colonies, or some other language. But what they tend to find offensive is speech that's arrogant, condescending, disrespectful of another's rights, impatient, and rude; or the equivalent in the accompanying behavior.

Brazilians tend to be an easy-going and people. They tend to appreciate tourists and visitors knowing something of Brazil's official language. For they tend to be proud of their nation's music, language, history, culture and accomplishments. Likewise, they tend to be respectful of other cultures and other languages. For their country often is described as a meltling pot of cultures and languages. And so Brazilians tend to welcome interactions with visitors to their country. And so it isn't other peoples speaking with them that Brazilians find offensive. What they find offensive is other peoples speaking to them in an arrogant, condescending, rude way that disrespects human rights and common courtesies.
Hebrew
Brazilians find it offensive when people speak impatiently, and in a rude way to them. For Brazilians are used to some tourists, and indeed some people worldwide, not knowing that there even is such a thing as the Portuguese language. They also are used to some tourists, and indeed some people throughout the world, trying to speak Portuguese according to Spanish grammar and vocabulary. And so they're used to dealing patiently and respectfully with other cultures and languages.
No. Brazilians tend to be adaptable, easy going and welcoming. They tend not to be offended by the choice of language. For they're proud of their country's reputation as a melting pot of cultures, languages, and peoples. But what they do find offensive is an obnoxious attitude that shows through in arrogant, condescending, discourteous, impatient or rude behavior and speech. Brazilians are used to respecting the rights of others, in order to work as a multicultural nation. And so it's offensive when tourists and visitors don't return such a hospitable attitude and manner.

I completely agree with the above paragraph. And last, but not least, if someone does not know which language Brazilians speak it is a question of education and lack of knowledge. Thus, it would not offended me, indeed.

I think it based on Bali and Sansakrit, the same base as Indian language.

Olá,

Olhe, se essa pergunta fosse em inglês, eu teria dificuldades em respondê-la porque não sou 'expert' em assuntos espaciais. Mas como respondedores aqui no WikiAnswers em português são raros, vou me arriscar a dar minha opinião.

Quero crer que OS ônibus espaciais são as naves que retornam à terra com tripulação, sem sair de um certo limite no espaço. A principal vantagem que consigo imaginar é a de que humanos, OS astronautas, adquirem mais e mais conhecimentos em relação às "pequenas" jornadas no espaço, possibilitando no futuro viagens mais distantes. Espero estar cérto nesta minha pequena resposta, que já é alguma coisa para você. Obrigado pela pergunta.
