课件64张PPT。Welcome!A long time ago,
there was a huge tree.It loved a little boy.
The boy loved to come
and play around it
whenever he was free.While apples riped(成熟),
He climbed to the tree top
and ate the apples.When he was tired,
he took a nap under
the shadow.As the time went by, he
had grown up, he never played
around the tree.Because I’m no longer
a kid now. I don’t play
around the tree anymore.
I need money to buy toys. The tree said,“Sorry,I don’t
have money,but you can pick
all my apples and sell them.
So,you will have money.” The boy was so
excited the time he heard it.
He grabbed(攫取) all the
apples and left happily.For the boy never came back
after he picked the apples,
the tree was sad.The tree wasn’t excited
until the boy returned one day.The tree said
”Come and play with me”.I don’t have time to play.
I have to work for my family.
We need a house for shelter.
Can you help me?“Sorry,but you can chop off(砍掉)
My branches to build your house.”So the man cut all the branches
of the tree and left happily.As soon as the man returned,
the tree was delighted.The man said “I am sad and getting old,
So I want to go sailing to relax myself.
Can you give me a boat?”“Use my trunk(树干) to build
your boat”,The tree said.The man cut the tree trunk
and made a boat.The tree was happy, but not really The tree had been ill for a long time
since the boy went sailing.Finally, the boy returned after
he left for so many years.Sorry,my boy. I had some leaves
not long before you come back,but
I don’t have anything for you now.“I don’t need much more,just a place
to rest. I’m tired after all these years.”
The boy replied.“Good!Old tree roots are the best
place to lean(倚靠) on and rest.Come,
come sit down with me and rest.”The man sat down and the tree was glad and smiled with tears…The tree is our parent.
