princess(公主)in the school play.For weeks my mother had
helped me practice my lines.But once onstage,every word disappeared from my
head.Then my teacher told me she had written a narrator's(解说者的)part for the play,and asked me to change roles.Though I didn't tell
my mother what had happened that day,she sensed my unhappiness and asked if I
wanted to take a walk in the yard.
It was a lovely
spring day.We could see dandelions(蒲公英)popping through the grass in bunches,as if a painter had touched our
landscape with bits of gold.I watched my mother carelessly bend down by one of
the bunches."I think I am going to dig up all these weeds,"she
said."From now on,we'll have only roses in this garden."
"But I
like dandelions,"I protested."All flowers are beautiful-even
dandelions!"
My mother
looked at me seriously."Yes,every flower gives pleasure in its own
way,doesn't it?"she asked thoughtfully.I nodded."And that is true of
people,too,"she added.
When I realized
that she had guessed my pain,I started to cry and told her the truth.
“But you will be a
beautiful narrator,”she said,reminding me of how much I
loved to read stories aloud to her.
Over the next
few weeks,with her continuous encouragement,I learned to take pride in the
role.The big day finally came.A few minutes before the play,my teacher came
over to me.“Your mother
asked me to give this to you,”she said,handing me a
dandelion.After the play,I took home the flower,laughing that I was perhape the
only person who would keep such a weed.
