阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

On the first day of school we were challenged to get to know a new classmate. I was looking around, when a gentle hand touched my shoulder. I found a little old lady with a warm smile.

She said, “Hi, handsome! I'm Rose. I'm 87 years old. Can I give you a hug(拥抱)?” I laughed and heartily responded, “Of course!”

“Why are you in college at such a young, innocent(天真的)age?” I asked.

She jokingly replied,“I'm here to meet a rich husband, get married, have children, and then travel around.”

“No, seriously,” I asked. I was curious why she took on this challenge at this age.

“I always dreamed of having a college education and now I'm getting one!” She told me. We became instant friends.

Over the year, Rose became a campus icon(偶像)and she easily made friends wherever she went. She loved to dress up and she enjoyed the attention from the other students. She was living it up.

At the end of the term we invited Rose to speak at our football banquet. I'll never forget what she taught us.

“We do not stop playing because we are old; we grow old because we stop playing. Here are the secrets to staying young. You have to laugh and find humor every day. You've got to have a dream. When you lose your dreams, you die. We have many people walking around who are dead, and they don't even know it!” she said.

“There is a huge difference between growing older and growing up. Anybody can grow older. That doesn't take any talent or ability,” she added. “But growing up requires finding the opportunity in change. The elderly usually don't have regrets for what they did, but rather for things they did not do.”

One week after graduation that year, Rose died peacefully in her sleep. She taught us by example that it's never too late to be all you can possibly be.
