A long time ago, snail has wing actually, it is what reason after all, let snail there is wing? The matter still must speak of from the beginning.
很久以前，蜗牛其实是有翅膀的，到底是什么原因，让蜗牛没有翅膀了呢？事情还得从头说起。
One day, snail spreads out wing flying, fly to branch a little while, fly to leaf a little while, fly to lotus leaf again a little while. At this moment, rain had below the sky, snail thinks: Rained, puppy people affirmative meeting comes in my house, I can not want to there are a lot of people in the home that allows me!
有一天，蜗牛展开翅膀在飞行，一会儿飞到树枝上，一会儿飞到叶子上，一会儿又飞到荷叶上。这时，天空下起了雨，蜗牛想：下雨了，小动物们肯定会到我的房子里来，我可不想让我的家里有很多人呢！
At this moment, caterpillar of a wool walked over, light tone says: "Can I take shelter from the rain to your home? " snail shakes his head, keep a straight face say: "Be no good, you will be flyblown of my home. " an ant also asked same word, snail still shakes his head, keep a straight face say: "Be no good, you will be flyblown of my home! " so it carried a house on the back at once, hide into a corner slowly.
这时，一只毛毛虫走了过来，轻声说：“我可以到你家躲雨么？”蜗牛摇了摇头，板着脸说：“不行，你们会弄脏我的家的。”一只蚂蚁也问了同样的话，蜗牛还是摇了摇头，板着脸说：“不行，你们会弄脏我的家的！”所以它连忙背起了房子，慢慢地躲进了一个角落。
Gradually, rain stopped, snail thinks: I still am waited for all the time be here, in case the house that the animal enters me, how to do? From now on, snail also did not fly on a sky again, defend all the time in the home. As a result of long trashy wing, wing also degrades accordingly.
渐渐的，雨停了，蜗牛想：我还是一直待在这里吧，万一有动物进我的房子，怎么办？从此，蜗牛再也没飞上天空，一直守在家里。由于长时间没用翅膀，翅膀也因此退化掉了。
Perhaps be God sees snail is so selfish, punish it to carrying a house on the back forever then, also take no less than coming again, later, what it climbs is slower and slower.
也许是老天爷看到蜗牛这么自私，于是罚它永远背着房子，再也拿不下来了，后来，它便爬的越来越慢了。
