Now I'm feeling that my English is really improving Good Afternoon people!! Going to the point, I would like to share the fact that my English is improving each day. I'm training a lot my listening, a little bit speaking and almost never or little bit reading and write. But even only training more listening, my English impressive is staying better each day over time. My strategies are: watch videos on youtube of several types, courses online and mainly free, and another materials. Thus, my English is improving slowly but consistant. My vocabulary is staying better also even sometimes I forgetting many of them. The grammar is good even making mistakes on accasion. Sorry for the short text.. Thanks in Advanced for the corrections.

Sunday Today it's Sunday. Now in Brazil it is 12:39 p.m, it's sunny although be winter. I'm studying a lot: - English, Espanish, programming and also reading a Stephen King's book Wizard and Glass. It is with that I spend my time on Sunday. I know that it is not healthy but I like so much. Huh!! Almost I have forgot I watch series and movies too.

I love series!!! Good evening!!! As it is on the title, I love series, mainly fiction, terror, adventure, super heroes, of course (hahahah). Actually I'm watching DC's Legends of Tomorrow. Good, but it's very simple script, effects and actors acting a little bit bad no one save yourself it's funny. The main heroes are unknown at least for me, although, appears reference about famous heroes, like The flash uniform or the green arrow. In general, the series it is good for fun without worry about the rest. Later I write more this is was the begin. Thanks in advanced!!!
