He is barking
.
I heard the bell ring
.
He is flying
.
They are walking
.
He is hiking
.
They have long necks
.
He is a wise king
.
They are playing
.
She is waiting
.
She is washing the dog
.
She is learning
.
He sat on the swing
.
They are rowing
.
The ring is new
.
I need to buy the string
.
Amy is reading
.
She is building
.
He is stirring
.
She was throwing the ball
.
