Kitts is one of "Tomorrow's people"—people who have electronic body parts. She has an electronic arm. One year, Kitts lost her arm in a truck accident. She felt angry and sad. She couldn't accept it. But then she heard a piece of good news that a doctor could use her remaining nerves (神经) in her shoulder to fix an electronic arm.

Before long, the doctor decided to move Kitts's nerves to different areas of her top arm. For months, the nerves grew and moved deeper into their new homes gradually. After three months she started feeling a little painful. The doctor helped her a lot to reduce (减少) pains. A month later, her pains disappeared and she got her new electronic arm. An engineer worked with Kitts to connect the computer programs with her real movements more and more closely.

Today, Kitts's arm is great, but it's not yet perfect as normal people. She wants feelings in her hands. For example, she needs to feel whether something is smooth or not. She also needs feelings to do one of her favorite things—drinking coffee. One time at a coffee shop, she, together with her friends, wanted to drink coffee as they talked happily. However, her hand kept closing until it broke the coffee paper cup. "One day I'll be able to feel things with it, and clap my hands to the songs my kids are singing…" she said with hope and pride.

—Yes. __________ good time we are having!

It was two months before Christmas when nine-year-old Rose told her father and me that she wanted a new bike. Her Snow White bike was just too old to ride, and it needed repairing as well.

As Christmas came closer, her dream for a bike seemed to disappear, for she didn't mention it again. We were busy buying some beautiful storybooks, a doll house, a holiday dress and toys.

Then much to our surprise, on the evening of December 24, she said she terribly wanted a bike more than anything else.

Then we didn't know what to do. It was just too late for us to make her dream come true. So there was no time to buy the "right bike" for our little girl. Thinking that we were parents who would make their child unhappy, we tried to deal with the problem.

Suddenly my husband came up with an idea. "What if I make a little bike out of clay and write a note that she could trade in the model bike for a real one?" "Perfect!" I shouted. So he spent the next five hours carefully working with clay to make a small bike.

On Christmas morning, we were so excited to wait for our daughter to open the little box with the beautiful red and white clay bike and the note. She opened it and read the note loudly. She looked at me and her father, and said, "So, does it mean I can trade in this bike for a real one?" Smiling, I said, "Yes." Rose had tears in her eyes when she replied, "What a wonderful surprise I have! I will never trade in this beautiful bike that Daddy made me. I prefer to keep it rather than get a real bike." At that moment, we would have bought her every bike on the earth.

—Yes, I do. And you can see that books are made _______ paper.
