I do not speak English, what better way to ask in English?

Hello!

I'm from Brazil, and unfortunately I know very little about idiome English. PS: I admit that it is a failure, "and that must be corrected," but it sure takes time. Currently I have used the google translator to translate language text English to Portuguese. I have achieved great results, but I want to participate but my english sucks.

It is unethical, incorrect, rude, etc., use the google translator to communicate with people of other languages???

There is some other way or another tool to ask questions in other languages??? Not only pergunas but help in the responses, ie, also contribute. Someone could tell me some tips to help solve this problem?

Sorry for my bad English, I used google translator.

thank you Junior
