     Sue is only five.  She doesn't go to school.  And of course, she doesn't know how to read and write.

But her sister, Ann is a schoolgirl. She is eleven. One day, Ann saw her little sister at the table with a

pen in her hand and a big piece of paper in front of her.

     "What are you doing, Sue?"Ann asked.

     "I'm writing a letter to my friend, Lily. "

     "But how can you? You don't know how to write. "Ann said.

     "Well," Sue said. "It doesn't matter (这没关系).  Because Lily doesn't know how to read. "
