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.

A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food, police and local media reported on Saturday.
The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words.
He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside.
The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19.
“Just incredible that he’s alive considering that he had no food, but also since it’s been really cold for some time after Christmas.” a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news.
Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time.
“We would not make up something like this. The rescue services were on site too and saw the same as us.” he told Vasterbottens-Kuriren.
Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.
Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like(休眠似的) state, physician Stefan Branth told Vasterbottens-Kuriren.
“A bit like a bear that hibernates. Humans can do that.” he said. “He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up.”
“Why the man ended up under the snow in the forest remains unknown,” police said.
