回复：Well read, and have a solid foundation in pronounciation

but I do feel obliged to comment on as I do hope that people here can help each other to progress together. Here're some places which caught my attention the most. They may not be right, just for your reference.
1. the /ts/ sound in United States needs to be improved;
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".
3. you added /i/ sound in the second syllable in word "business";
4. when pronouncing the /er/ sound the so-called /R/ sound, you should finish the vowel sound well before pronouncing the "r" sound, it seems you pronounced it too abruptly and too quick. (hard for me to explain).
5. "employer", /cy/ sound is missing, it should be pronounced as /cie/ (here, the "c" is the mirrored letter sound, and the "e" is the upsidedown one).
6. "official", the emphasis should be in the second syllable, and you stressed the first syllable.

Hope this helps and note that they are friendly reminders on you pronounciation. Some may not be right, just my two cents.
