I was thinking about you today and how you could keep up to date with your English this summer.
Here you have a list of websites where you can find interesting listening activities:
(I specially like "Private lives" series
You also have other links on the right-hand side of the blog, for example, audio books and other resources.
It is also a good idea to watch films in English (try not to use subtitles progressively) as well as to read books. You could even start reading authentic books! I mean, not adapted... Well.. but you already know about this!
Have a nice summer (and don't forget to add some podcasts to your mp3!)
