For most pregnant women, exercise is the last thing on their minds．After all, keeping slim while you’re expecting isn’t exactly the top priority— rather, it’s making sure your baby gets enough nutrients to grow．But in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life．

The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance（胰岛素抵抗），a condition eventually leading to diabetes（糖尿病）．Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal（胎儿）development．In pregnant women, this condition means nutrients get shunted to the growing baby．

The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulin．So the University of Auckland’s Dr．Paul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise（有氧运动） might have on their insulin sensitivity and, ultimately, on their babies’ birth weight．Researchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exercise．When the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothers．In both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights．

Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging result．Even more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb．

Mr. Clinton and his 13-year-old son Tony are basketball fans．Last October 10^th was Tony’s birthday, so Mr. Clinton decided to drive him to New York, for the first game of the World Series．They had no ticket but hoped to buy a pair from scalpers.

   It was a two hours’ ride．After they arrived, they walked in the street for two hours, carrying a sign（牌子） that read, “ We need two tickets.” There were many scalpers around, but the cheapest ticket was $200．They were about to leave when suddenly a man stopped them．He took out two tickets and handed them to Mr. Clinton.

 “How much do you want?”

    “Just a present,” said the man．“Enjoy the game.”

    Mar Clinton wouldn’t accept, so the man explained, “I’m Jackson．Hans is my boss．He and his wife haven’t missed a World Series in 18 years．But he is ill and can’t watch the game this time．So he told me to give the two tickets to people who I thought would actually enjoy the game．A lot of people looked as if they might just take the tickets and sell them．Then I saw you and I followed you for a while．You seemed very disappointed．You made me think of my dad and me when I was a child．I dreamed of going to a World Series game with my father．But my dream never came true.”

    How do you suppose this made Mr. Clinton and his son feel? Here is what Mr. Clinton said: “This is the most wonderful thing that ever happened to us．My boy and I must have turned to each other over 30 times and said, ‘I can’t believe this.’ We still never forget Jackson and Hans.”
