Oh, don't worry, you're just beginning, it's not like you should know everything so quickly;
my best piece of advice would be:
learn how to compound short, direct phrases, i.e.,
-Eu fui ao supermercado
-Alimentos são guardados na geladeira
-Eu estou feliz
just simple stuff: subject, verb, noun, that's more than enough for now, and don't worry about verb's conjugation, this is a pain, but the best thing is that you don't need to choose simple past of present perfect for the past ^_^
A sim, Agrias, desculpe a demora, eu estava acompanhando uma discussão muuiiiiito interessante la na agonia...
