Bi ht: Listening Practice Through Dictation CD 2-32 - V.A

Unit 32 Stop Yawning!
W: Stop yawning, Jason!
B : Im sorry, Ms. Terry. I cant help it!
W: You can! You yawn because your lungs need
more oxygen. When you need more oxygen, you
open your mouth wide and take in a lot of air.
B : What can I do to stop yawning?
W: You should go outside into the fresh air and
breathe deeply. Then you wont need to yawn
anymore. Your lungs will have lots of oxygen.
B : We just came in from recess, so why am I yawning?
W: Are you tired? Being tired also makes you yawn.
This is because your body needs rest. Oxygen
helps your body rest. Sleeping rests your body
and makes you take long, deep breaths.
B : Then, why do I yawn when I am bored, Ms.
Terry?
W: Well, Jason, when you are bored, you are probably
not breathing deeply enough. The best way to
stop yawning from boredom is to do something
interesting. If you cant do that, try taking deep
breaths. This will not stop the boredom, but it
will help you stop yawning
