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.

For centuries,the only form of written correspondence (通信)was the letters were,and are,sent by some form of postal service,the history of which goes back a long way .indeed,the egyptians began sending letters from about 2000 BC,as did the Chinese a thousand years later.

   Of course,modern postal service now are march more developed and faster.depending as they do on cars and planes fore delivery.Yet they are stell too slow for some people to send urgent documents (紧急文件)and letters.

   The invention of the fax (传真) machine increased the speed of delivering documents even more.When you send a fax you are sending a copy of a piece of correspondence to someone by telephone service.It was not until the early 1980s that such a service was developed enough for bussinesses to be able to fax documents to each other.

They will be Slumdogs no more．The two kid actors who broke our hearts in the Academy Award—winning “Slumdog Millionaire” are being moved out of their miserable Mumbai slum（贫民区）  into real homes with roofs and doors and walls．

    Rubina Ali and Azharuddin Ismail，who played the young Versions of the two main characters，won’t have to pay anything—their new digs are free．“These two children have brought honors to the country，” said Gautam Chatterjee．head of Mumbai’s housing authority．So for 10 -year-old Azharuddin，it’s goodbye to the simple tent by a busy road that was his family home．And for 9-year-old Rubina，it’s goodbye to the one room house she shared with her family．

The trees arrived by post, a half – open parcel. They were him and straight, rather like arrows but with shiny leaves at one end and muddy roots at the other. Terry and his father took them down to the garden and planted them in their prepared places. Terry had great hopes of the middle tree, now set in the holy spot where Herry, his cat, run over, had been laid to rest a year before. The nine trees made an avenue down one side of the garden, where there was already a fifteen – foot stone wall between the garden and the backyards of the Jenkins Street houses.

“Why do we want a row of trees as well as a wall?” Terry asked his father. His father said, “For privacy. These trees grow very thickly.”

His father’s love of privacy often puzzled Terry, who was not one to keep himself to himself, but he could see part of the point here. The houses in Jenkins Street were on higher ground. His friend Leslie lived at number twelve, and he had only to stand on a box to see right over the wall.

“Will the trees grow higher than the wall?” Terry asked then. “Oh yes, twice as high if not more. It’ll take a few years but they’ll grow.”

So they were going to have nine trees thirty feet tall, to keep them from being overlooked. Terry wondered why this was so desirable. He said, “Our garden is very pretty. Why can’t we let the people over the wall see it? That wouldn’t be showing off, would it?”

“No, I don’t think it would be,” his father said. “Yet some people might feel a bit less happy if they can always see a good thing isn’t theirs. We don’t want to be the cause of any jealousy if we can help it.” This consideration for other people’s feelings must be a grown-up thing. Terry thought. It was not his idea of how to run things. He said, “It seems a lot of trouble to go to stop people being jealous of us.”

His father looked at him. “It isn’t much trouble, Terry,” he said. “These trees will grow without help from us. They’ll be beautiful. And you can already hear them whispering to us in the wind.”

Americans are less inclined to get married than at any time in US history, posing social and public-policy dilemmas（困境）and the threatening to dissolve the “glue” that connects fathers to their children, experts say.

A report released by the US National Marriage Project found “a rather weakening of the institution（制度）of marriage” in America. The researchers said the US marriage rate has never been lower, births to unmarried women have skyrocketed, the divorce rate remains high and Americans’ marriages are less happy than in the past.

“There is no known society that has got along without marriage and has done a decent（体面的）job in rearing and sponsoring the next generation,” said Barbara Dafoe Whitehead, US National Marriage Project co-director.

The crumbling（崩溃）of the institution of marriage should not be viewed as a kind social trend with no costs to society at large, added the project’s other co-director, David Popenoe.

US government statistics cited（援引）in the Rutgers report detail a crisis（危机）in marriage whose origins can be traced back about 40 years. The report, citing census data（调查统计）,said the marriage rate has quickly reduced by a third since 1960. It said there were about 73 marriages per 1,000 unmarried women aged 15 and up in 1960. In 1996, the last year for which such figures were available, the rate was about 49 per 1,000.

Popenoe said the US marriage rate now has dropped below a previous historic low recorded at the turn of the century. He said several factors have something to do with the trend. One is that Americans are delaying marriage until they are older.

In 1960, the median age for first marriages was 20 for women and 23 for men. In 1997, with many college-educated Americans delaying marriage until their 30s, the median age rose to 25 for women and 27 for men, the report said.

“The later the marriage, by and large, the lower the (overall) marriage rate in the long run. In other words, people delay too long and then they decide not to marry after a while,” Popenoe said.

In addition, many American women, particularly black women, are giving birth and raising children without getting married.

In 1960,5.3 percent of all US babies were born to unwed mothers, according to government statistics. In 1997,32 percent of all babies were born to unmarried women－and a startling 69 percent of black babies had unwed mothers.

The percentage of US children living without their father present also has ballooned. In 1960, nine percent of children lived in a single－parent household. Last year, 28 percent of all children and 55 percent of all black children lived with a single parent. Children in single－parent households overwhelmingly live with their mothers, with fathers absent.
