    It's going to be Sport Day on Friday. There are some students on the playground.

    They are doing sports. Amy is running. She can run fast. Sam is jumping. He can jump really high. Daming is playing football. He can play it very well. What is Lingling doing? She is playing basketball. She can catch the ball. But she can't catch it very well.

 话说一个国王没有儿女，打算从民间选一个小孩做王子，办法是给候选者每人一颗牡丹花种，看谁种的花儿最漂亮、花儿最多。到了评比的时候，几乎所有的小孩都捧着鲜艳漂亮的牡丹花，只有一个小孩捧着空花盆伤心落泪，他没有种出花来。但是，恰恰是他被选中了，因为所有的花种都被煮熟了，是不能开花的。
国王看中了那伤心落泪小孩的什么道德品质？你从中获得哪些感悟？
