Please think of ONE www site which you like and visit very often. There are THREE things I would expect of it:
- that it is in English
- that it is dynamic, which means it changes and offers new things on a more or less regular basis (it could be a blog, a podcast, a newspaper or TV channel site, an online video series with episodes published regularly - anything of that sort)
- that it does not promote violence towards anybody
As far as I'm concerned, I sometimes visit, and strongly recommend to those who (rightly) feel English is an endless learning curve, a site called "The Free Dictionary". It offers really challenging vocabulary tasks (hangman, matching, spelling bee or Scrabble) as well as different types of information, including "Quotation of the Day", "This Day in History" and so on. I visit the site quite often as it never fails to surprise me with something, at the same time allowing me to relax a bit between more "serious" tasks. It's just fun to do these puzzles and find out about new words and new facts. Give it a try! :)
