完型填空开头是 a group of graduates,highly established in their car

A group of graduates,highly established in their careers,got together to visit their old university professor.Conversation soon turned into complaints about stress in work and life.
Offering his guests coffee,the professor went to the kitchen and
returned with a large pot of coffee and an assortment(variety) of cups -
porcelain,plastic,glass,crystal,some plain looking,some expensive,
some exquisite telling them to help themselves to the coffee.
When all the students had a cup of coffee,the professor said:"If you
noticed,all the nice looking expensive cups were taken up,leaving
behind the simple and cheap ones.While it is normal for you to want
only the best for yourselves,that is the source of your problems and
stress.Be assured that the cup itself adds no quality to the coffee.In
most cases,it is just more expensive and in some cases even hides what we drink.What all of you really wanted was coffee,not the cup,but you consciously went for the best cups...Then you began eyeing each other's cups.
Now consider this:Life is the coffee; the jobs,money and position in society are the cups.They are just tools to hold and contain Life,and the type of cup we have does not define,nor change the quality of Life we live.
Sometimes,by concentrating on the cup,we fail to enjoy the coffee God has provided us.
Enjoy your coffee!"
The happiest people don't have the best of everything.They just make
the best of everything."
Live simply.
Love generously.
Care deeply.
Speak kindly.
Leave the rest to God.
You are the miracle,my friend;
your life either shines a light OR casts a shadow!
Shine a light & enjoy the Coffee!
