WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.
Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.
The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.
"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.
"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.
"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."
The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.
1.What's the research really about?
A. Boys and girls. B. Food and weight. C. Sleep and health. D. Screens and fat.
2.What's the result of less sleep for teenage boys?
A. Bigger waist and more fat in the body.
B. An increase in weight and height.
C. More concerned with their diet.
D. A decrease in bone and muscle.
3.From the sixth paragraph we can infer that ______.
A. girls usually sleep less and have healthier lifestyles than boys
B. the researchers expected to see the same result in girls
C. peoples' diet has a great effect on their health
D. boys are usually lazier than girls
4.Who would be the most pleased to hear the news?
A. Teachers. B. Girls. C. Parents. . D. Boys.

Sons who have fond childhood memories of their fathers are more likely to be emotionally stable（稳定的） in the face of day-to-day stresses, according to psychologists（心理学家） who studied hundreds of adults of all ages.
“As our study shows, fathers do play a unique（独特的） and important role in the mental health of their children much later in life,” Psychology professor Melanie Mallers of California State University said.
For this study, 912 adult men and women between the ages of 25 and 74 completed short daily telephone interviews about that day’s experiences over an eight-day period. The interviews focused on the participants’ psychological and emotional distress (i.e., whether they were nervous, sad, etc.) and if they had experienced any stressful events that day.
The participants were also required to answer questions such as, “How would you rate your relationship with your mother during the years when you were growing up?” and “How much time and attention did your mother give you when you needed it?” The same questions were asked about fathers.
People who reported they had a good mother-child relationship reported three percent less psychological distress（忧虑） compared to those who reported a poor relationship, according to Mallers.
Men who reported having a good relationship with their father during childhood were more likely to be less emotional when reacting to stressful events in their current daily lives than those who had a poor relationship, according to her findings.
Also, the quality of mother and father relationships was significantly associated（有关） with how many stressful events the participants faced on a daily basis. In other words, if they had a poor childhood relationship with both parents, they reported more stressful incidents over the eight-day study when compared to those who had a good relationship with their parents.
Mallers theorized why healthy or unhealthy relationships may have an effect on how people handle stress as adults. “Perhaps having caring parents equips children with the experiences and skills necessary to more successfully navigate（导航） their relationships with other people throughout childhood and into adulthood.” She said.
【小题1】What can we know about the recent study from the passage?
A It was led by Melanie Mallers.
B 912 adults who were over twenty-five joined in it.
C It lasted as long as eight days.
D It was funded just by California State University.
【小题2】Which of the following may the participants be asked about in telephone interviews?
A Their physical condition. B Their parenting（育儿） skills.
C Their emotional distress and stressful events.
D Their childhood relationships with teachers.
【小题3】Which of the following statements is TRUE?
A Many people with good parent-child relationships still can’t keep emotionally stable in stressful incidents.
B Men with a good mother-child relationship were more likely to be emotionally stable when reacting to stressful events.
C Women were better at getting along with their parents than men when they were young.
D People with good childhood relationships with parents suffered（遭受） fewer stressful incidents.
【小题4】What can be concluded from the findings of the study?
A Childhood memories of parents have a lasting effect on one’s ability to handle stress.
B Adults with good childhood relationships with parents will live happily and successfully.
C The mother-child relationship is more important than the father-child relationship.
D The quality of parent-child relationships determines（决定） how people handle stress as adults.
