      春雨，像春姑娘纺出的线，没完没了地下到地上，沙沙沙，沙沙沙……

     一群小鸟在屋檐下躲雨，他们在争论一个有趣的问题：春雨到底是什么颜色的？

     小白鸽说：“春雨是无色的，你们伸手接几滴瞧瞧吧。”

     小燕子说：“不对，春雨是绿色的。你们瞧，春雨落在草地上，草地绿了，春雨淋在柳树上，柳树绿了。”

     麻雀说：“不，不！春雨是红色的。你们瞧，春雨洒在桃树上，桃花红了。春雨滴在杏树上，杏花红了。”

     小黄莺说：“不对，不对，春雨是黄色的。不是吗？它落在油菜地里，油菜花黄了，它落在蒲公英上，蒲公英的花也黄了。”

     春雨听了大家的争论，下得更欢了，沙沙沙，沙沙沙，它好像在说：“亲爱的小鸟们，你们的话都对，但都没说全面。我本身是无色的，但我给春天的大地万紫千红。”

阅读课文，说说小鸟们在争论一个什么问题？
