READING :Read the passage , and do the tasks that follow .

Nick's voice is changing . It is one of the many developments that happen to both girls and boys when they reach puberty : a boy's voice gét deeper than a girls 's.

At puberty , boy's bodies begin producing a lot of the hormone testosterone , which causes in several parts of the body , including the voice . For starters , a boy's larynx , also know as the voice box , grows bigger , which causes your voice to get deeper.

Along with all the other changes in your body , you might notice that your throat area looks a little diferent . For boys wherevihe larynx grows bigger , part of it sticks out in the part of the neck at the front of the throat and forms the Adam's apple . For girls , the larynx also grows bigger but not as much as a boy's . That is why girls don't have Adam's apples.

While your body is getting used to these changes , your voice can be difficult to control . A guy's voice "cracks " or "breaks" because his body is getting used to the changing size of his larynx . Fortunately , the cracking and breaking is only temporary . It usually lasts no longer than a few months.
