Just stumbled upon this, thought it may be useful practice material (about 20 podcasts).
"Since 2006, the weekly Skeptoid podcast has been taking on all the most popular myths and revealing the true science, true history, and true lessons we can learn from each.
The Chinese version is simply translations and recordings of the same content, but in Mandarin. I’ve spent a fair amount of time listening to Skeptoid Chinese. Here’s why:
Interesting content – It’s refreshing to hear sombre reasoning about various myths, some of which I wasn’t even aware of. Most episodes are well researched and make a decent effort to summarise research into various topics. This isn’t unheard of in English, but I don’t know any other resource like this in Chinese (if you do, please let me know!).
Audio and text in both English and Chinese – Since this is based on the English original, you can get the content in whatever format and language you want. Being able to read the Chinese article and hear it at the same time is very useful. It’s also useful to be able to check the English text for details or nuances. The Chinese translation is idiomatic and well worth studying. The audio is probably a little bit too fast for some students, but it’s still well produced and clearly enunciated.
Just the right length – Each episode is roughly 8-12 minutes. Since this is packed with content, it will keep you occupied a lot longer. I think this length is just about right; it makes it possible to get into the subject and the flow of the episode, but is still short enough to squeeze into a busy schedule. When I found the Chinese version of Skeptoid years ago, I was really bored with podcast episodes that were too short.
It’s free – Just like the original Skeptoid, the Chinese version is offered for free. You are encouraged to support it, but that’s all. You can download all the episodes as mp3 files and browse the text versions online. In case you missed the link above, just click here to browse all the episodes."
