Pronunciation: 学习英音还是美音好？

> 现在美音很流行，我学美音很吃力，听也听不清楚，英音感觉和上海话
> 像多了，也清楚，可是现在都是学美音的，就怕学了英音还受美音影响，
> 成了mixture。

If you expect to talk to Americans more, practice American pronunciation. If you talk to the British people, practice British. If you don't know, then it doesn't matter. A mixture of pronunciation is perfectly acceptable, as long as you pronounce words clearly. People living in the New England area of the US have a mixed pronunciation. Nobody laughs at them.
