Breastfeeding (母乳喂养) for a month or longer appears to reduce a womans risk of getting diabetes (糖病) later in life, according to a new study. The breastfeeding and diabetes link has been reported in other studies, according to researcher

2、 Eleanor Schwarz. Yet, her study makes the link easier to believe. Her study is published in a journal of medicine in America. Schwarz and her colleagues looked at data about breastfeeding practices. They evaluated data on 2,233 women from California. Of those, 405 were not mothers, 1,125 were mothe

3、rs who breastfed for at least a month, and 703 were mothers who had never breastfed. They were 40 to 78 years old. According to Schwarzs study, the risk of getting a diagnosis (诊断) of Type 2 diabetes for women who breastfed all their children for a month or longer was similar to that of women who ha

4、d not given birth. But mothers who had never breastfed were nearly twice as likely to develop diabetes as women who had never given birth. Mothers who never breastfed were about 1.4 times as likely to develop diabetes as women who breastfed for one to three months, Schwarz found. While one month of

5、breastfeeding appears to make a difference, Schwarz says, even longer is better. (80) “Previous studies have shown the longer the mom breastfeeds, the more benefit for her body.” Many experts recommend breastfeeding for six months and continuing for a year, she says. The diabetes-breastfeeding link

6、is probably explained by belly fat. Mothers, who dont breastfeed, as they get older, may have more belly fat, as breastfeeding helps new mothers take off weight. “Belly fat increases the risk of diabetes as you get older,” she says. The finding isnt surprising at all, says Kimberly Gregory. She ofte

7、n gives advice to women who get diabetes (occurring during pregnancy (怀孕) that they are at risk for later getting Type 2 diabetes and suggests they breastfeed. The new findings will probably inspire Gregory to add to the-advice she gives moms-to-be about the benefits of breastfeeding. She often focu

The most famous collections of fairy tales (童话) are the ones by Jakob and Wilhelm Grimm. The Grimms published their first fairy-tale collection in 1812. They didnt think they were writ

15、ing for children. They thought they were preserving disappearing German folk culture. Their first edition(版本) was a scholarly book that carefully recorded the oral tales. They were surprised when some of their early readers suggested that the stories might be interesting to children. But the Grimms

16、needed money. They had made a bad deal with their publisher and received little payment for their first book. At one point Wilhelm complained there wasnt a chair in his house one could sit on without worrying it would break. So he took the hint and set to work to make a book that would be suitable f

17、or children. He selected a few of the tales, made them much longer, and polished up the language. He didnt add morals, but he did slip in character judgments and moralizing comments wherever he could. The Grimms fairy tales also have one characteristic that would seem to make them unsuitable for chi

18、ldren. Many of them include violent incidents. In “Hansel and Gretel” an old woman is burned to death in an oven, and in “Little Red Riding Hood” a child is eaten by a wolf. When he revised the tales for children, Wilhelm Grimm retained the violence. In fact, he sometimes even ramped it up. For exam

19、ple, in the first edition of the tales, Cinderella forgives her sisters at the end. Its only in the second edition, the one intended for children, that her birds peck(啄) out their eyes. Why, then, have the Grimms fairy tales become classics of childrens literature, so much so that it is hard to imag

20、ine a child who doesnt know Cinderellas story or Snow Whites? One answer is that only a few of the tales survived into modern times. The first edition of the Grimms fairy tales had 210 tales. By 1825 it was down to 50. And today only a dozen or so of the tales are often reprinted in childrens collec

21、tions. But the deeper answer is that the tales that have lasted are magical adventures that help children deal with the struggles and fears of their everyday lives. 6. Why did Wilhelm Grimm set out to adapt his book for children? A. To deal with readers complaints.B. To improve his financial situati

As the school year kicks off, parents are once again straggling to cajole(哄编) and, if need be, drag their exhausted teens out of bed. That image may make you laugh

27、, but lack of sleep is no joke. Teenagers who dont get enough rest have more learning, health, behavior and mood problems than students who get at least nine hours a night. Long-term lack of sleep is tied to heart disease, overweight, depression and a shortened life span in adults, indicating the im

28、portance of establishing good sleep habits early in life. Lack of sleep can be especially deadly for teens; car accidents are the leading cause of death among teenagers, and safety experts believe sleepy driving is a major factor. Unfortunately, few teenagers get the sleep they need. In a survey of

29、middle- and high-school students, University of Colorado researchers found that 82 percent said they woke up tired and unrefreshed, and more than half had trouble concentrating during the day at least once a week. Blame multitasking for some of this. Many students are juggling after-school activitie

30、s, homework and part-time jobs. Even when they manage to fulfill these obligations by a reasonable hour, television, the Internet, video games, phone calls and text messages to friends often keep them awake deep into the night. Taking soda and energy drinks late in the day and going to late-night pa

31、rties on weekends add to sleep debt. Biology also works against teenagers sleep, The bodys internal clock, which controls when a person starts to feel tired, shifts after puberty (青春期), making it hard for most teens to fall asleep before 11 pm. Class usually begins before 8:15 am, with many high schools starting as early as 7:15 am. To get to school on time, most teens have to get up by 6:30 am, guaranteeing theyll be sleep-deprived during the week. Teens often sleep much later on we
