Sam is a bus driver in a big city.All day he drives a bus through busy street.Driving a big bus is very _51__ work.It makes some drivers unhappy.But not Sam!
Sam is always happy.And the people who ride in his bus seem to be happy,too.This story shows _52__.
Early one morning,Sam started his big green and yellow bus.He went off on _53__ work."Oh,what a beautiful morning!" he sang."Oh,what a beautiful day!"
At the first bus stop,a man was _54__."Good morning,Mr.James," said Sam with a big smile."How are you?" "Fine,thank you,Sam," said Mr.James."How are you?"
"Wonderful!" Sam answered."Just WONDERFUL!This is a fine day."
Mr James smiled.He took a seat.As he looked _55_ the window,he still smiled.
At _ 56__ stop a man came running up.He was puffing.(气喘) "I have to catch a train at seven," he said."Can you get me to the station?"
"Now,just sit down and rest," said Sam."I'll drive a little __57_ .We will be there in time.Then you __58_ run again."
"Thank you!" said the man.He sat down.
Sam did drive just a little faster.He got to the station before seven!
"Thank you," said the man,as he got off the bus."You are the best bus driver in the city!"
As he drove on,Sam __59_ talking again.By this time,many people were on the bus.They were all going to work.But Sam made the ride seem like fun.
"It is now ten minutes after seven," Sam called out,"The sky is blue,it's fine today.We all like sunshine,don't we?"
He began to sing,"I love you,Mr.Sunshine.I love you,Mr.Sun.In all the world I love you best.You are the only one."
"What is that song,Sam?" a girl asked.
"It's my song," he said,"I made it up.I like to sing.It makes __60_ people want to sing,too."
Sam was right!The man behind him started to sing!
