A father and his son went to a kite-flying festival. The son was happy when he saw the sky 1  colorful kites. He wanted to fly a kite, too. The father then bought a kite for his son. 

The son started to fly the kite. Soon, his kite was high up in the sky. After a while, the son said, "Father, it seems that the string（线）is 2 the kite from flying higher. If we cut it, it will be 3 and fly even higher. Can we cut it?" The father agreed. The kite started to go higher. This made the little boy 4 .

But then, slowly, the kite started to come down. It soon 5 to the ground. The son was surprised to see this. He said to his father, "I thought that after cutting the string, the kite would fly higher. 6 did it fall down?"

The father explained, "The string was not stopping the kite from going higher, 7 was helping it stay in the sky. You helped the kite go up in the right 8 using the string. But when you cut the string, it could 9 support the kite. "

We may sometimes feel like there are certain things 10  are holding us back and stopping us from growing. But in fact, these might be the things supporting us the most.
