No one really knows how and why people change as they get older. Also, no theory sufficiently explains all the changes of the aging process. Aging is a complex and varied process that varies in how it affects different people and organs. In fact, even in one person , different organ systems “age “ at a different rate.

    At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.

   Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.

    There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.

    What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!

The underlined phrase “bounce back ”means “__________.”

   A. jump backward     B. run fast    C. prevent     D. recover

In order to make people live longer, scientists _______according to the text.

   A. teach people how to eat properly

   B. discover how important the exercise is to one’s health

   C. study the ways to slow or stop the process of aging

Many consider the later part of life to be the time of living because they__________.

  A. consider their lives have been very successful

  B. have come through the battle of life safely

  C. know more about themselves and the outside world

  D. can have a good rest and enjoy themselves

How many factors which decide our health are mentioned in the text?

  A. Two  B. Four   C. Five   D. Six

A few years ago, I had the opportunity to play the character of Ronald McDonald for the McDonald's Corporation.
One day each month，we visited hospitals bringing a little happiness to the children there. But there were two rules placed on me during a visit. First, I could not go anywhere in the hospital  without permission. And second, I could not physically touch anyone within the hospital. They did not want me to carry germs(细菌)from one patient to another. Breaking either of these rules, I was told, I could lose my job. One day, as I was heading down a hallway and on my way home, I heard a little voice coming through a half­opened door，“Ronald，Ronald.”
I stepped in and saw a boy，about five years old, lying in his dad's arms, Mom with a nurse on the other side. I knew by the feeling in the room that the situation was grave. I asked his name. He told me it was Billy and that I did a few simple magic tricks for him. As I stepped back to say good­bye, he asked me “Ronald, would you hold me？”
At such a simple request, my heart was screaming, “Yes！”But my mind was screaming louder. “No！You are going to lose your job！”
“Hold me” was such a simple request, and yet I searched for any reasonable excuses that allowed me to leave, but none. It took me a moment to realize that in this situation, losing my job may not be the disaster I feared. Then, I picked up this little boy. He was so weak and so scared. We laughed and cried for 45 minutes. With tears in my eyes, I left them. Less than 48 hours later, I received a phone call from Billy's mom that Billy had passed away. She and her husband simply wanted to thank me for making a difference in their little boy's life.
Billy's mom told me shortly after I left the room. Billy looked at her and said, “Momma, I don't care any more if I see Santa this year because I was held by Ronald McDonald.”
For the record, McDonald's Corporation did find it out, but, given the situation，permitted me to go on with my job. I continued as Ronald for another year before leaving the corporation to share the story of Billy and how important it is to take risks.
