The best way to learn proper English is to read news report, and watch news on TV. Watching TV shows is a great way to learn casual English, slang words, understand culture reference and humor. If you have already watched these shows then you may recall the words used in the following dialogs.

We have the advantage,
more men, more horses, all fed and RESTED.
Game of Thrones Season 5, Episode 5

I don't think God RESTED
on the seventh day, Bernard.
Westworld Season 2, Episode 7
