听力原文： People who are overweight at 40 are likely to die at least three years sooner than those who are slim, meaning that being fat during middle age is just as damaging to life expectancy as smoking, re searchers say in a new study. The study was conducted by Dutch researchers and is published in The Annals of Internal Medicine.
Nonsmokers who were classified as overweight, but not obese, lost an average of three years off their lives. Obese people died even sooner. Obese female nonsmokers lost an average of 7. 1 years, while obese male nonsmokers lost 5.8 years.
Scientists have long known that overweight people have shorter life expectancies, but few large scale studies have been able to pinpoint how many years they lose. "This study is saying that if you are overweight by your mid-30's to mid-40's, even if you lose some weight later on, you still carry a higher risk of dying," said Dr. Serge Jabbour, director of the weight-loss clinic at Thomas Jefferson University Hospital in Philadelphia. "The message is that you have to work early on your weight. If you wait a long time, the damage may have been done."
For smokers, the results were worse. Obese female smokers died 7.2 years sooner than normal weight smokers and 13.3 years sooner than trim nonsmoking women. Obese male smokers lived 6.7 years less than trim smokers, and 13.7 years less than trim nonsmokers.
The results were culled from 3,457 volunteers in Framingham, Mass. , from 1948 to 1990. The data were analyzed by researchers at Erasmus Medical Center and the University of Groningen in the Netherlands.
About two-thirds of American adults are overweight or obese, according to the Centers for Disease Control and Prevention. Studies have also shown that people are getting fatter at younger ages.
"The smoking epidemic in the Western world is waning; however, a new fear should be the in creasing prevalence of overweight and obesity in young adults, which shows another potentially preventable public health disaster." the researchers said.

W: Yellowstone! I've always wanted to spend some time out in Wyoming.
M: Wait till you hear what the project is... She's working with the buffalo population. The herds have been increasing in size lately, which is good in theory...
W: Yeah... but I thought they were in danger of becoming extinct.
M: Well, apparently, because of all the winter tourists, paths are created in the snow. More buffalo are surviving the harsh winters because the paths make it easier for the buffalo to move around and find food. But it turns out that some of the herds are infected with a bacteria.
W: Oh yeah, I heard about that. Bru—
M: Brucella abortus
W: Right, It's been around for quite a while.
M: Yes it has. And because the buffalo population is increasing, they've been roaming more than usual, and the disease has begun to spread to the cattle ranches that border toe park.
W: That's bad news! Isn't that the disease that causes animals to abort their young？
M: Yes, and it's caused a lot of controversy. Some of the ranchers even want to destroy the buffalo herds.
W: That's awful! Have they made much progress with the research？
M: So far, they've been collecting tissue samples from dead buffalo to see if the bacteria's present.
W: I'd really be interested in working on this. You know I've been researching diseased animal populations...
M: That's why I thought of you... I took the liberty of mentioning your name to my friend. She's ho ping you'll be able to spend the whole summer out there.
W: Well, I was going to work on my thesis a lot in July, but I'm sure my adviser wouldn't want me to pass up this opportunity.

听力原文： Megan Della Selva, a sophomore at George Washington University, has already traded e-mail messages with her mom, just to say hi, Maria Minkarah, the friend she is having lunch with, has just talked to her dad, to report on a doctor's visit and her latest thoughts about studying abroad. The young women keep in close touch with their families, discussing matters big and small, academic and
personal. Interviews with students on a variety of campuses suggest that many turn to their parents for help with everything from roommate troubles to how to improve the paper they e-mailed home. Perhaps the most striking thing was the tone students had when talking about their parents. , fond, warm and admiring. The sense of parents as people to be admired was widespread.
Not all college students are this closely connected with their parents. But university officials, students and their families say that the generation gap is nothing like what it used to be, now that baby boomers, once so alienated from their parents, have become parents themselves. "This generation of parents is more involved," said Jennifer Bell, coordinator of the parents office at North Carolina State University. "Thirty years ago, parents were content to drive their kids to college, drop them off, and pick them up at graduation. Now there are different expectations, because they've been involved in their kids' lives all through school."
Cellphones and e-mail have a lot to do with what university administrators and parents alike say has been a big change over the last decade. Hundreds of colleges nationwide have recognized the new reality by giving parents a stronger presence on campus, through a host of offices created to deal with parents' queries and concerns.
