Usborne has a series of audio read-along books, of short stories, fairy tales, and kids' versions of the classics like Treasure Island. Each is read by a different British narrator. I had to smile when I overheard the girls re-reading the books to themselves in their very own British accents; but then a chuckle crossed my lips when I overheard them play-acting with those same British accents.
Hopefully after this trip to Taiwan, I shall hear them play-acting more in Chinese than in English.
