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.

A. bring benefits to a baby’s growth
B. lower the risk of insulin resistance

D. To compare the differences between mothers who exercise and who don’t
4. 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 exercise on birth weight before.

My dream was 18 . By the time I was sixteen, I started playing baseball. I could throw a ninety-mile-per-hour fastball and 19 anything that moved on the football field.

A friend recommended me for a summer job. This meant a chance for money in my pocket—money for a new bike, new clothes and the 24 of savings for a house for my mother. Then I realized I would have to 25 up summer baseball to handle the work schedule, and that meant I would have to tell John I wouldn’t be playing.
When I told John, he was 26 as I expected him to be. “You have your whole life to work,” He shouted. “Your 27 days are limited.

Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens(过敏原),prompting researchers to ask: Are cats and dogs really safe for children?
A study finds that, contrary to many parents' fears, owning cats or dogs does not increase a child's risk of developing allergies, and in fact, may actually protect them. The study's lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child's allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
1.Why do the researchers feel “very surprised” by the results of the study?
A.Because the results are contrary to their expectation.
B.Because so many children are playing with cats and dogs.
C.Because parents are so much worried about their children.
D.Because children with animals may develop allergies easily.
2.Compared with children who have pets,those who haven’t ______.
A.will lose the chance to develop immune system
B.may suffer allergic diseases more often
C.will reduce the harm from bacteria
D.can keep doctors away
3.It can be inferred from the passage that ______.
A.pets are ill-treated by their owners
B.less families would like to own cats and dogs
C.keeping pets is a good way to keep children healthy
D.the results of the study can make families with pets feel at ease
4.The underlined word “it” in the fifth paragraph refers to________.
A.the early life
B.an allergic disease
C.immune system
D.something important
5.What may be the best title of the passage?
A.How to protect your kids from allergies
B.Your pets may be helping your kids
