Free to fly with the wind
One windy spring day, I observed young people having fun by flying their kites in the wind. Colorful creations of varying shapes and sizes filled the blue and clean skies like beautiful birds dancing. As the strong winds blew against the kites, a  16   kept them in control.
Instead of blowing away with the wind, they went up against it to achieve great  17 . They shook and pulled, but the control string and the long tail kept them under  18  , facing upward and against the wind. As the kites struggled and trem­bled against the string, they seemed to be saying,  " Let me go t Let me go! I want to be  19  !" They flew beautifully even as they fought the control of the string. Fi­nally, one of the kites  20   in breaking loose. "Free at last," it seemed to be saying, "Free to fly with the wind.”
Yet freedom from control simply put it at the   21 of an unsympathetic wind. It dropped ungracefully to the ground and landed in a wild mass of weeds. “Free at last”--- free to  22 powerlessly in the dirt, and to be blown  23  along the ground……
How we are like kites sometimes! The Heaven gives us adversities(逆境), limits and rules to ­­­­_ 24  from which we can grow and gain strength. Control is a necessary opponent（对手） to the winds of opposition. We can never go up high enough to achieve our goals sometimes if we lose our necessary  25 or the rules.
