Exercise 10-3: Allz Well That Endz Well     CD 4 Track 33 

Repeat the Z sounds in the paragraph below.

A lazy Thursday at the zoo found the zebrasgrazing on zinnias, posing for pictures, and teasing the zookeeper, whose nose wasbronzed by the sun. The biggest zebra'sname was Zachary, but his friendscalled him Zack. Zack wasa confusing zebra whose zeal for reason caused his cousins, who were naturally unreasoning, to pause in their conversations. While they browsed, he philosophized. As they grazed, he practiced zen. Because they were Zack's cousins, the zebras said nothing, but they wished he would muzzle himself at times.

As mentioned on page 84, like sounds follow naturally. If one consonant is voiced, chances are, the following plural S will be voiced as well. If it's unvoiced, the following sound will be as well. In the past tense, S can be both voiced [z] and unvoiced [s] in some cases.
