A door was locked．A big stone came and hit the door．But he couldn’t 　　1　　 it．Later a key came．He 　　2　　 the lock and the door opened．The stone was very 　　3　　 that the key could open it so easily．He asked the key：“　　4　　 did you do that?”The key 　　5　　 him and said：“Because I understand its 　　6　　．”

　　Life is just like this．　　7　　 we want to solve a problem, we must understand it 　　8　　．If we want to make friends with people we must understand 　　9　　．If we want our parents to 　　10　　 us, we must first know their hearts．We must know what they hope for．
