40一道闪电从黑暗的天空劈向了沙漠，沙漠中下起了罕见的一场雨。

　　A lightning struck to the desert from the dark sky. A rare rain come to the desert.

　　小蜗牛倒在卷着边的叶子里，他躺在盛满了雨水的叶子里哭起来。他的身体开始饱涨起来，这使他可以流出眼泪来。

　　The little snail lay down on the withered leaf. He cried in the leaf full of rain. His body began to swell after absorbing water, which enabled him to tear.

　　“这是妈妈的眼泪啊！她在告诉我，孩子，这样做是对的！我可以坚持下去。”小蜗牛对自己说。"This is mother's tear! She is telling me, my child, you are right to do so! I can insist." The snail said to himself.

　　趁着潮湿，小蜗牛又急急忙忙赶路了。

　　Under the cover of moisture, the little snail set off again.
