回複：第400多遍跟讀"The happy door--穀興", 多謝指教!

Please don't care too much about pronounciation of single words.

Please pay more attention to rhythm. ( Unfortunately, I thought most of articles/books about pronounciation are not practical or even correct. )

I heard strong accent of Northeastern Chinese. Very probably Shenyang, am i right ?

My suggestion to you is, to follow some media readings read faster, or just sing some kids rhyme with you kids. The one you post here is not good for rhythm practice.
