A little stream（小溪） ran down from a high mountain through many villages and forests．Then it reached a desert．"I went through so many difficulties．I should have no problem crossing the desert，"she thought．As she started，she found herself slowly vanishing（消失）into the sand．After many tries，she still failed．"Maybe I can't reach the ocean，"she said sadly to herself．

At this time，a deep voice said，"If wind can cross the desert，so can a river．"It was the voice of the desert．But the little stream answered，"That's because the wind can fly，but I can not．""That's because you can't give up what you are．Let yourself evaporate（蒸发）into the wind and it can take you across me，"said the desert．"Give up what I am now？No!No!"The little stream could not accept this idea．"The wind can carry the vapor（蒸汽）across the desert and let it leave as rain．The rain will form a river again，"said the desert．"And whether you're a river or vapor，your nature never changes．"After hearing this，the little stream went into the open arms of the wind．It carried her to the next stage of her life．
