It was a quiet evening. The Greens were all in the living room at the moment. The father, mother and young daughter （enjoy）a game of catch with a ball of yarn（毛线球）. As they threw ball back and forth, it slowly became a knotted mess.
The little girl looked the knot angrily and said, "It is impossible to loosen（松开）this!" The father smiled took the yarn gently in his hands. He began （work）on the strings（线）, one by one, until the knot slowly loosened.
As he worked, he said, "Life is like this knotted string. Our （problem）and challenges sometimes seem impossible. But with patience, love, and a little bit of hard work, a way will （find）in the end."
The little girl watched （careful）as the knot became loose. When it was finally smooth again, she smiled and hugged （she）father. The family continued their game, but they had a （deep）understanding of the value of family and the power of love than just now. That is what truly makes a family strong.
