A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. Parents are supposed to _ when their kids are growing up. A) continue their broken marriage B) allow children to decide when to sleep C) limit teens' using new technology D) force teens to have 10 hours' sleep daily

Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.and the same could be true for people who eat too much sweet junk food,Israeli researchers said Monday. Fructose,found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt.But while its sweet taste is popular,the sugar could cause wrinkles,the researchers said.Dr.Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.Collagen basically holds the body together.The loss of collagen is what causes loose skin and deep wrinkles in older people. The process affected,Werman's team said,is known as"cross-linking "."Too much cross.1inking makes the skin stiff, and these are the conditions that encourage wrink1ed skin,"Werman said in a statement.He said the same could be true of people,although this has not been shown."Americans are eating more and more processed foods such as baked goods,canned fruits,jams is and dairy products that contain fructose,"Werman said.Other studies have shown that taking in high fructose may cause diabetes . The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were fed 12.5 grams of fructose per kg of weight everyday for a year. The best title for the passage should be" _ ". A) Sugar-it could reduce collagen B) Collagen-it could age you C) Collagen-it could cause wrinkles D) Sugar-it could age you
