I like podcast as a learning resource.
In the beginning, they converse in slowly way, so that I have time to think out what the word means.
Next he would tell us what the word means in English. I like this way.
Finally, We have read the topic, when they converse in normal speed, we can totally understand.
We can use podcast in convenience way, and I have a suggestion that if we can choose our favorite topic, that will be fun.
