Upon learning this news, Nancy & I had to decide whether as private citizens we would  36  this a private matter or we would make this news known in a  37  way.
In the past Nancy suffered from breast cancer  38  I had my cancer surgeries (外科手术). We found that after we told it to the public, we were able to  39  public awareness(意识). We were happy that  40   many more people went to have a test. They were treated in early stages and able to  41  to normal, healthy lives.

I will continue to share  47    journey with my beloved Nancy and my family. I plan to enjoy the great outdoors and stay in touch  48   my friends and supporters.
Unfortunately, as Alzheimer’s Disease  49 , the family often suffers a lot. I only wish there was some way I could spare Nancy from this   50  experience. When the time comes I am confident that with your help she will   51  it with faith and courage.
At last, let me thank you, the American people for giving me the great honor of  52   me to serve as your President. When the Lord calls me home,  53  that may be, I will leave with the greatest love for this country of ours and endless optimism (乐观) for its future.
I now begin this  54  that will lead me into the sunset of my life. I know that for America there will always be a bright   55  ahead.
Thank you my friends. May God always bless you.
Sincerely,
Ronald Reagan
