Recently I was invited to attend a party that helps children seriously injured in the big earthquake that happened this May. I went because I 31 . At the party, all the children were given paints in bright, beautiful colors. After a short time, as I 32 , I saw blue clouds, orange sunrises and purple flowers. The 33 were all bright. The boy sitting next to me was painting a heart, but it was 34 and lifeless. It lacked (缺乏) the bright colors that his fellow (同伴) “_35_” had used. I thought maybe he took the only paint that was 36 and it just happened to be dark. But when I asked him about it, he said his 37 was that color. I asked him why and he told me that he was very 38 .

Those 50 really do work.” On my way home I felt my own heart had changed to a brighter color, too.
