Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine, too. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological clock.

Barbara Wells exercised every morning. She woke up at 6:00 am. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercises before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercises after work.” Her legs and back don’t hurt anymore.

Today, doctors are learning more about chronobiology (时间生物学), the study of biology clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep at the same time every night and to eat only when they’re hungry. Also, doctors discovered that some illness, such as heart attacks(心脏病), occur(发生)most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medicine at night, they may prevent a heart attack in the morning.

Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!

39. What can we learn from the passage?

It was the first day of school. I stood up to look around when a gentle hand touched my shoulder. I turned around to find a little old lady smiling at me.

She said, “Hi handsome. My name is Rose. I’m eighty-seven years old. Can I give you a hug?”

I laughed, enthusiastically responding, “Of course!” And she gave me a giant squeeze. “Why are you in college at such an age?” I asked.

“I’m here to meet a rich husband, get married, have children, and then retire and travel.”

“No seriously.”

“I always dreamed of having a college education and now I’m getting one!”

We became instant friends. Over the course of the year, Rose made friends wherever she went. She loved to dress up and she took great delight in the attention given to her from the other students. She was living it up. At the end of the term we invited Rose to speak at our football banquet (宴会) and I’ll never forget what she taught us.

As she began to deliver her prepared speech, she dropped her note card on the floor. A little embarrassed she simply said, “I’m sorry. This whiskey is killing me! I’ll never get my speech back in order so let me just tell you what I know.” As we laughed, she cleared her throat and began: “We do not stop playing because we are old; we grow old because we stop playing; There are only four secrets to staying young, being happy and achieving success. You have to laugh and find humor every day. You have got to have a dream. When you lose your dreams, you die. We have so many people walking around who are dead and don’t even know it! There is a huge difference between growing older and growing up. If you are nineteen years old and lie in bed for one full year and don’t do one productive thing, you will turn twenty years old. Anyone can grow older. That doesn’t take any talent or ability. The idea is to grow up by always finding the opportunity in change. Have no regrets. The elderly usually don’t have regrets for what we did, but rather for things we did not do.”

At the year’s end Rose finished the college degree. One week after graduation Rose died peacefully in her sleep. Over two thousand college students attended her funeral(葬礼) to honor the wonderful woman.
