 　　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 visible¹ 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 vibrate²,

　　and you can feel that vibration³ 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.
