I want to ask 2 questions about pronunciation first:
1) Do Americans say /use-d/ or /use-t/ in used to?
2) I saw Ann Cook wrote this in American Accent course:
If the first consonant is voiced, the next one will be as well. If the first one is unvoiced, the second one will sound unvoiced, no matter what you do.
Then she gave out examples:
After a voiced sound: He had to do it /he hae (d) d' du(w)'t/
After an unvoiced sound: he got to do it / he ga(t)d' du(w)'t/
a)(note that the words in bracket (d) (t) (w) are small and stand upper to others, I wonder whether we pronounced them)
b) How do those examples support the cause she gave, but I've seen no reason why. After t( unvoiced), we still pronounce: 'd, and so does after (d), so what's the difference?
3)What is the difference between rate and incidence?
4) "Lifting bar bell helps your pectorals expand" or ""Lifting bar bells helps your pectorals expand"
1) Do Americans say /use-d/ or /use-t/ in used to? - Americans say 'YOOstoo'.
2) He got to do it / he ga(t)d' du(w)'t/ - This means Americans pronounce it as [hee ga T' du w't] or [hee ga D' du w't]
4) "Lifting bar bell helps your pectorals expand" or ""Lifting bar bells helps your pectorals expand" - barbell (sing.), barbells (plur.)
Lifting a barbell helps your pertorals expand. - This is the right sentence. the other sentence implies that the person lifts more than one barbell at the same time.
