Here are a some links to different sites that I like for English.
The English Learner Blog is written by Michal, a Polish guy and it is very well written.
I love recommending BBC’s Newsround because it is news for kids, but it is a great way for adults to get news vocabulary.
Antimoon has great resources, including a fantastic International Phonetic Alphabet chart for English. I don’t agree with all of their advice, but I do agree with a lot of it.
