1 . Many years ago, when I worked as a volunteer at Stanford Hospital, I got to know a little girl     1    (name) Liz who was suffering from a rare and serious disease. Her only chance of    2    (recover) appeared to be a blood transfusion（输血）from her 5-year-old brother,     3     had miraculously survived the same disease and had developed the antibodies needed to fight the     4    (ill).

The doctor    5    (explain) the situation to her little brother, and asked the boy if he would be willing to give his blood to his sister. I saw him hesitate for a moment before taking a deep breath and saying, “Yes, I’ll do it     6     it can save Liz.”

As the transfusion progressed, he lay in bed next to his sister    7    smiled, as we all did,     8    (see) the color returning to her cheeks. Then    9    (he) face grew pale and his smile faded. He looked up at the doctor and asked with a trembling voice, “Will I start to die right away?”

Being young, the boy had    10    (understand) the doctor; he thought he was going to have to give his sister all of his blood.

2 . It was a sunny day. A little boy’s father was sitting on the couch, drinking a beer, while     1     (watch) a basket match. Seeing this, the boy rushed to his father and shouted, “Daddy, Daddy, show me how to play catch!” The father,  staring      2      the television screen, replied, “Let me finish watching     3     match. Play outside and come back in five minutes.”

“Okay, Daddy!” said the boy, running out of the room. Five minutes later, the boy returned, screaming , “Daddy, let’s go. Let’s play catch now !”

By this time, the father had opened another cold beer and another match was beginning.     4      (patient) with the boy’s interruption, the dad brought a magazine to his son. On the cover of the magazine was a large picture of the world. The father, who     5     (bother) and angry, began tearing the magazine cover into small     6    . Then, the father turned to his boy and said, “Son, once you put this picture back together, we can play catch,  but do not interrupt me again     7     you finish.”

A few minutes later, the boy returned and said, “I     8     (finish),  Daddy! Can  we play catch now?” Surprised, the father glanced towards his child, and there lay the magazine with the world together. The dad asked his child     9     he put the world together so quickly.

“    10     was  simple,” said the boy. “On the back of the world was the picture of a person, and once I put the person together, that’s when the world came together. ”
