Brazil is a large country in South America, with about 200 million. (it sounds more natural to put more information in one sentence. Don’t forget to capitalize names like South America.
There ARE 26 states AND (use the word, not the symbol when writing sentences) One (use the word and not the symbol) Federal District.
They are: Minas Gerais, São Paulo, Rio de Janeiro, Amazonas, Acre, Tocantins, Rio Grande do Sul, Mato Grosso do Sul, Bahia, Roraima, Rondonia, Amapá, Para, Goias, Maranhão, Ceará, Paraiba, Pernambuco, Alagoas, Sergipe, Piaui, Espirito Santo, Paraná, Santa Catarina, Mato Grosso and Distrito Federal that is a Federal District.
Because THERE ARE so many states, I (use a capital letter if you are talking about yourself) don’t know one person who has VISITED ALL OF THEM.
I only went TO (The word TO is a direction. For example, “I go TO the store.”) Rio de Janeiro, Espirito Santo, Santa Catarina and Minas Gerais.
Many people think that Brazil is only Carnaval, sex and crime, but it is not. For example, FEW people know what Carnaval is.
MOST people think that Carnaval (use a capital letter for names) is what they watch on television. That there are naked women in Rio de Janeiro.
But, EVERY state in Brazil celebrateS Carnaval like that. In Ouro preto, for example, ARE music shows and people drink beer or caipirinha.
AS FOR the sex, all people CAN have sex if THEY want. Not just here. THERE ARE mEn and women who have no sex before MARRIAGE, and SOME who do.
CRIME is A really big problem here. I think IT is because OF social inequality. Here WE have a lot of poor people. (There must be a subject of the sentence.)
WE have a lot of corruption too. Recently, our GOVERNMENT stole a lot of money in a state company PETROBRAS.
I think the problem is the people BEcause they put this person in a power.
However, WE have a lot of good things here too. For the rich people the life is like in THE United States (the proper name of the country is THE United States. To be correct you must use the word THE) or other developed country.
WE have a lot of trees, beaches, and amazing places.
A good place for you TO visit is Fernando de Noronha, Rio de Janeiro (COPA CABANA, IPANEMA, BARRA DA TIJUCA, CABO FRIO, ARRAIAL DO CABO), Florianópolos, some places in NORDESTE, and others.
Very nice job.
