回复：Thank you. You are nice.

Feedback:

1. the /ts/ sound in United States needs to be improved;---I was confident for this pronounciation. Still do not know what is wrong. If it is possible, can you let me know how to pronounce it?
- this might be a one-time happening.

2. you add /l/ sound in several words, lik, "company", and "industry", where the first syllabble in "company" is pronounced as /vl/ (note the "v" indicates the updidedown letter); and /vl/ in the second syllable of "industry". ----do you mean I pronounced them as com-pvl-ny, and in-dvl-stry?
- yes.
