Appropriate
Avoid when
You say 'wǒ hái méi qù guo Zhōngguó' (我还没去过中国). This uses 还没去过 to mean 'haven't been yet'.
It's pronounced 'wǒ hái méi qù guo Zhōngguó' with the third tone on wǒ, second on hái, second on méi, fourth on qù, neutral on guo, first on Zhōng, and second on guó.
Use 还没去过 when you want to emphasize that you haven't done it yet but might in the future. 没去过 simply states the lack of experience without that nuance.
