L1 and L2 interference - audio samples

[Piotr]

Hi, I'm a student of a Polish Training College For Foreign Language Teachers.
First of all, I'm not sure if I start this topic in the right category but I hope somebody will help me.

I'm working on a presentation showing L1 and L2 interference and I desperately need audio samples of this. Especially language calques but every other examples of interference (pronunciation and so on) are welcome. Could anybody give me a link to such files or maybe record it for me? It can be interference of English with any other language.

You can get samples simply by going into a school where the pupils are using an additional language
