Once there was a teacher who took all his students for tea. What made the students    1  was that all the cups on the table were  2  . Each of them took a cup and started   3 their own tea, looking at the   4  cups.
The teacher said; "Do you notice your   5 ? You are all looking at each other's tea cups and  6  of you even envy (羡慕) the   7  cups of others."Then he went on: "I put the different cups here on purpose! Life is like    8  tea. You all have the same thing in your cups— tea. And yet you can't  9  enjoy it in your envy of another's cup. You forget   10  your own life when you envy someone else's life. So now, taste your own tea! Does it matter from which cup it comes from?"
