回複：need to practice consonants [tr] and [ch]

I really appreciate your comments. Tr and ch sounds are my difficult sounds. Thanks a lot to point them out.

Intonation and stresses are actually the developing areas in this phase. Is it too much to ask an example whichI did wrong? When I hasn't reached the certain level, it is difficult to do self-correction by just listening to myself. That is why I was so passionated about muscle theory of pronouncitation. But I have no efficient way to do the same for intonnation and stress.
