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．
