Once again, science supports what your grandmother told you: A good night's sleep helps your body fight a cold.

People who averaged fewer than seven hours of sleep per   1   in the weeks before being exposed to the cold virus were nearly three times   2   likely to get sick as those who   3   eight hours or more, a new study found.

Researchers used frequent telephone   4   to track the sleep   5   of more than 150 men and women aged 21 to 55 over the course of a few weeks. Then they   6   the subjects to the virus, quarantined them for five days and kept   7   of who got sick.

  8   sleeping more, sleeping better also seemed to   9   the body fight illness: Patients who fared better on a measure   10   as 'sleep efficiency' - the percentage of time in bed that you're actually sleeping - were also   11   likely to get sick.

The results held   12   even after researchers   13   for variables such as body-mass index, age, sex, smoking and pre-existing antibodies to the   14   .

  15   your grandmother, the researchers aren't exactly sure   16   sleeping better makes you less likely to   17   a cold. But they   18    take a stab at the answer: 'Sleep disturbance influences the regulation of proinflammatory cytokines（促炎细胞因子）, histamines, and other symptom mediators that are released in response to infection.' In plain English, maybe tossing and turning when you're   19   with the cold virus   20   to the symptoms that define a cold.

The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.

Growing up, I always dreamed of being a professional figure skater. After years of hard work, I am living proof that dreams can come true.

I started taking group skating lessons, and performing on ice came naturally, but I have always been  39  to speak in group settings. One thing I've never been afraid of is  40  , though. I get nervous, but never  41  . For me, skating has been about being my personal best  42  beating others on the ice. 1 progressed through various  43 rapidly and gave my first ice performance at seven. Soon I started winning local and regional competitions. That's  44  being on the ice has always been the one place where I can  45   express my own emotions. The ice is like home.

When I was nine years old I began training  46 . I would wake up at four o'clock in the morning six days a week and skate for five hours. Then I'd go to school. Since  47  has always been important in my family, I had no  48  but to find creative ways to fit in school studies throughout my  49  career.

After graduating from high school, I moved to Canada and set out to train full-time to give my dreams a chance at reality. In 1992 I went to compete in the Olympic Games.  50 , not my coach or even my family, ever talked to me about winning a gold medal. In fact, I wouldn't even  51  myself to think about it. I thought that would disturb me.  52 , I went with the attitude that I wanted to enjoy the Olympic spirit.  53  the expectation of all the people, I won the gold medal and words couldn't describe the overwhelming mixture of emotions I felt. Then I truly understood what  54  most in achieving a dream is nor to  55  it when you 1ace difficulties, but strive to make it come true.

One day a very wealthy father took his son on a trip to the country with the firm purpose of showing his son how poor people can be.

They spent a couple of days and nights on the farm of  36  would be considered a very poor family. On their  37  from their trip, the father asked his son, “ How was the trip?”

“It was  38 , Dad .”

“Did you see how poor people can be?” the father asked.

“Oh yeah?” said the son.

“So what did you  39  from the trip?” asked the father.

The son answered, “I saw that we have one dog and they have four. We have a pool that  40  to the middle of our garden and they have a creek (小溪) that has  41  end. We have lanterns in our garden and they have the  42  at night. We have a  43  piece of land to live on and they have fields that go  44  our sight. We have servants who serve us, but they serve  45 . We buy our food, but they grow theirs. We have  46  around our property（财产） to protect us but they have friends to protect them.”

With this the boy’s father was  47 .

Then his son  48 , “Dad, thank you for showing me how  49  we are.”

Too many times we  50  what we have and concentrate on what we don’t have. What is one person’s  51  object is another’s prize possession. It’s all  52  on one’s perspective (视角). Think about what would happen if we all gave  53  for what we have,  54  worrying about what we don’t have.

Be thankful for every single thing in your life, exactly as it is now–and  55  your friends. Be sure to take the time to express your appreciation and gratitude for the people whom you are close to.
