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.

You return from work on a hot August evening. Your unwashed teenage son is on the sofa scrolling through Instagram, as he has been doing for the past eight hours. Not for the first time, you ask yourself: why are school summer holidays so insufferably long?
This is a more serious question than it sounds. Many children will return from the long break having forgotten much of what they were taught the previous year. One study from the American South found that this "summer learning loss" could be as high as a quarter of the year's education. Poor children tend to be the worst affected, since rich ones typically live in homes full of books and are packed off to summer camp to learn robotics, Latin or the flute.
Summer holidays vary greatly from country to country. South Korean children get only three weeks off. Children in Italy and Turkey get a whopping three months. So do those in America, where their parents, unless they are teachers have an average of only three weeks off a year, among the shortest holidays in the rich world. Companies should let them take a bit more, since burnt-out workers are less productive. But, for their children six weeks out of class is plenty.
Youngsters will hate the idea of a longer school year. Sceptics note that, although those barely rested South Korean pupils do superbly in exams, they are often miserable. It would be unwise to import South Korea's pressure-cooker approach, in which a single exam determines every child's future. But plenty of Western children could usefully spend a bit longer at their books.
More time in school need not mean repeating the same old lessons. Some extra drilling would be beneficial, particularly for those falling behind. But the summer could also be a time for different wind of learning: critical thinking, practical skills, financial literacy, work placements with local firms — schools should be free to experiment.

A.long school summer holidays B.addiction to smartphones

3.In the author's opinion, how long is the summer holiday supposed to be?
A.Three weeks. B.Six weeks.
C.Two months. D.Three months.
4.What is the author's suggestion?
A.Schools should try new approaches to teaching.
B.Schools should provide more exams for students.
C.Schools should think about how to make the best use of the summer time.
D.Schools should offer more materials for students to do laboratory experiments.
