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, rearchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exerci 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, becau exerci 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 exerci put her developing baby’s food supply at risk? Past studies looking at the effect of exerci on birth weight have been inconclusive, and none have really investigated the influence of exerci on the mother’s nsitivity 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 exerci(有氧运动) might have on their insulin nsitivity and, ultimately, on their babies’ birth weight. Rearchers asked some women to exerci on a stationary bicycle for at least 40 minutes per ssion, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exerci. 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 tho 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 exerci did not em to affect the flow of nutrients to the growing babies in the womb. 1. According to the new study, a pregnant woman’s regular exerci may _______. A. bring benefits to a baby’s growth B. lower the risk of insulin resistance C. put her baby’s food supply at risk D. help her keep slim and healthy2.

To find out what aerobic exerci can benefit a baby’s growth. C. To make sure of the effects exerci may have on babies’ birth weight D. To compare the differences between mothers who exerci and who don’t4. Which of the following statements is true according to the passage? A. Lighter babies are generally believed to be healthier than heavier ones. B. Non­－exercising mothers will definitely give birth to heavier babies. C. No studies have looked at the effect of exerci on birth weight before. D. Some women studied were asked to exerci regularly while some don’t.5.
