   Exercise 7-2:


  Targeting The TH Sound
  In order to target the TH sound,
  first, hold a mirror in front of you
  and read our familiar paragraph silently,
  moving only your tongue.
  It should be visible 1 in the mirror each time you come to a TH.
  Second, find all of the THs,
  both voiced and unvoiced.
  Remember, a voiced sound makes your throat vibrate 2,
  and you can feel that vibration 3 by placing your fingers on your throat.
  There are ten voiced and two unvoiced THs here.
  You can mark them by underscoring the former and drawing a circle around the latter.
  Or, if you prefer, use two of your color markers.
  Pause the CD to mark the TH sounds.
  Don't forget to check your answers against the Answer Key, beginning on page 193.
