谢谢你祥尽的答复。

总结一下，好象就是用进废退。我所以好奇问这个，是因为我自己说三种语言（方言也算一种，每一句都说得结结巴巴的语言也算进来了 :-) ）, 现在英语没学会，连原先说得很好的普通话偶尔也会发音不够标准，老家方言要回去呆两天才可正常发挥。你能把这么多语言同时维持在这么高的水平，真的很了不起！

I never feel you are crazy. On the contrary, I enjoy reading/listening to your postings, ignoring which language they are in, though I can't fully appreciate some of the songs in Catonese. You have already made very good progress in English pronunciation in the past few days.
