A study published Monday found that people who sleep less tend to be fat，and experts said it’s time to find out if more sleep will fight fatness.

“We’ve put so much emphasis on diet and exercise that we’ve failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

Monday’s study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

“Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

“Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

“Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

“We caution that this study does not set up a cause?and?effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

Inan interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神經(jīng)療法)in the brain governing sleep and fatness appear to overlap(部分重疊)，”he said.

“Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“l(fā)eading to a variety of health problems.”

Things You Should Quit Doing to be Successful

Would you like to be successful? But what are you willing to do in order to reach your goal? 1. If you want it bad enough, you will get it. When you are productive, you efficiently finish various tasks and achieve better results. However, there are many bad habits that successful people will try to avoid to reach their desired success.

They don’t do without first learning. The greatest thing about learning is the benefit that we receive in all aspects of our lives. If we stop learning, then the only thing we can do is settle with what we already know; if we settle for that, then there is no way to expand our minds. 2. Since our minds require learning for expansion, we must never stop seeking new knowledge.

They don’t work in their comfort zone. What is your comfort zone? Your comfort zone is defined as “A psychological state in which a person feels familiar, at ease, in control, and experiences low anxiety.” When you get outside of your comfort zone, it doesn’t mean that you should strive for a constant state of anxiety and stress. 3.

4. Social networks are great for staying in touch with family and friends. However, when chatting, posting, sharing, and looking at various funny photos, we waste hours just scrolling through pages. Usually, before we fall asleep, we decide to check if there is something new in the news feed and end up falling asleep very late at night. You then feel tired in the morning and incapable of doing anything that demands focus and hard work.

They don’t hang around negative people. Negative people are very harmful to be around when it comes to achieving success. 5. When you are around negative people enough, you start to see things negatively and you begin to lose sight of your dream. If that happens, life will reward you with negative outcomes to deal with.

A. They don’t fear asking for advice.

B. Expansion is essential on the path to success!

C. They don’t spend a lot of time on social networks.

D. Success is not something that happens by accident.

E. Getting lost in small things causes us to miss out on the overall views.

F. Success is more about a person’s way of thinking than anything else.

G. It simply means that, in order to grow, you should try new things and expand your horizons.

Hoverboards(電動(dòng)滑板）were among the most popular Christmas gifts of 2015. They may have also been most dangerous gifts of 2015.

A true hoverboard looks like a skateboard without wheels. To “hover” means to float in the air without moving much in any direction. The popularity of hoverboards began in the 1980s, with the “Back to the Future” movies. Characters in the second and third films used hoverboards as transportation.

This year’s popular hoverboards, however, do not actually hover. They have wheels. And? as it turns out, they are not easy to use.

Adults and children around the world suffered hoverboard-related injuries over the weekend. Many posted pictures of the damage on social media. Twitter user David Douglas posted a photo of both him and a young girl with the broken arms they suffered on Christmas Day. And another user Erin Rafferty uploaded a video of her mother falling off a hoverboard, with the caption, “Who let mom on the hoverboard?”

Falling is not the only risk with some hoverboards. They are also a fire risk. At one store in Texas, an employee tried to fix a hoverboard a customer brought in. The hoverboard then caught fire.

Studies suggest that some hoverboard brands have defective batteries or plugs.

Many major airlines worldwide have banned hoverboards because of the fire risk. But some passengers did not hear the news. Australian actor Russell Crowesaid on Monday about his disappointment that Virgin Australia Airlines did not permit his children to take their hoverboards on the plane.

Major retailers (零售商）are also taking steps to improve the safety of the hoverboards they sell. Amazon in the United States now only sells hoverboards from brands that have submitted safety standard documents. The UK’s Amazon no longer sells hoverboards. It has also advised customers who bought unsafe brands of hoverboards to throw them away.

1.What’s the problem with this year’s hoverboards?

A. They don’t have wheels. B. They catch fire in the sun.

C. They are difficult to handle. D. They can’t move in any direction.

2.We can infer from the passage that .

A. the number of hoverboard-related injuries is declining.
