…so say a couple of my students. Here are some suggestions:
If you like adventure stories, Jules Verne translations are good for low intermediate 2, because he uses short chapters, with quite a lot of action and movement in the stories. Try these: LibriVox
Or:
World News for Children (aimed at 11 - 14 year old native English speakers), 3 minutes long plus transcripts. (Intermediate 1 - low intermediate 2?)
Intermediate 2:
The BBC World Service’s podcast 6 minute English; BBC Learning English - 6 Minute English. Scripts, glossaries etc can be found on the website: Learning English - 6 Minute English
Advanced 1:
If you are interested in news stories, you could try picking a news item and finding a podcast and a news article on the same story. Although they won’t be identical, they will both be about the same story and contain very similar vocabulary. You could therefore listen to the audio and create lingQs from the (similar but not identical) text. You can use Wikipedia articles as a source of vocabulary for podcasts. The Wikipedia article won’t say the same thing as the podcast, but there will be much common vocabulary.
Try the World Service’s Witness podcasts, BBC Sounds - Witness History - Available Episodes.
Any more suggestions?
