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 cause­and­effect 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(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

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

Sleep to Lose Weight

A recent study found that people who sleep less tend to be fat. Experts said it's time to find out if more sleep can fight obesity.

Nowadays, the most popular method to keep fit is doing more exercise and eating less. Some people even take weight-loss drugs to keep slim, which is unhealthy and harmful to your body. " 1.As a result, we’ve failed to recognize the value of good sleep," said a physician.

Men sleep an average of 27 minutes less than women, and overweight and fat patients sleep less than patients with normal weights. In general, fat people just sleep about 1.8 hours less a week than those with normal weights.2.Only an extra 20 minutes of sleep per night contributes to a lower BODY MASS INDEX （身体质量指数）.

Are people less happy or more happy the older they get ? A study found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18.

The finding came from a Gallup survey of more than 340,000 adults between the age of 18 and 85 in the United States.

Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 22 and 25. Stress levels dropped sharply after people reached their fifties.

Happiness was highest among the youngest adults and those in their early seventies. But the people least likely to report feeling negative emotions were those in their seventies and eighties. The survey also found that men and women had similar emotional patternsas they grow older. However, women at all ages reported more sadness, stress and worry than men did.

The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

So why would happiness increase with age ? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

The original goal of the study was to confirm the popular belief that aging is connected with increased sleep problems. The survey did find an increase during middle age, especially in women. But except for that , people reported that they felt their sleep quality improved as they got older.

1.Old people may be happier probably because _________

A. their children have grown up.　　 B. they don’t have to work every day.

C. they can do whatever they like best.　　 D. they are most likely satisfied with life.

2.According to the survey, when will adults feel most stressful?

A. In their twenties.　　 B. In their fifties.

C. In their seventies.　　 D. In their eighties.

3.What may make Arthur Stone a bit surprised?

A. Women usually live longer than men.　　 B. Middle-age men mostly are very rich.

C. Old people usually have a better sleep.　　 D. Most of old people can’t sleep well at night.

4.Which of the following may be the topic of this passage ?

A. The difference between men and women.　　 B. Old people’s feeling of happiness.

The results from the world’s largest sleep study have shown that people who sleep on average between 7 to 8 hours per night perform better cognitively (认知地) than those who sleep less or more than this amount.

The world’s largest sleep study was launched in June 2018 and within days more than 40,000 people from the world participated in the online scientific investigation, which included an in-depth questionnaire and a series of cognitive performance activities.

“We really wanted to capture the sleeping habits of people around the entire globe. Obviously, there have been many smaller sleep studies of people in laboratories but we wanted to find out what sleep is like in the real world,” says Adrian Owen, western’s researcher in Cognitive Neuroscience and Imaging. “People who logged in gave us a lot of information about themselves. We had a fairly extensive questionnaire and they told us things like which medications they were on, where they were in the world and what kind of education they’d received because these are all factors that might have contributed to some of the results.”

More than half of all participants reported typically sleeping less than 6.3 hours per night, about an hour less than the study’s recommended amount. One shocking truth was that most participants who slept four hours or less performed as if they were almost nine years older.

Another surprising discovery was that sleep affected all adults equally. The amount of sleep associated with highly functional cognitive behavior was the same for everyone, regardless of age. Also, the harm associated with too little, or too much sleep did not depend on the age of the participants.

“We found that the best amount of sleep to keep your brain performing its best is 7 to 8 hours every night. We also found that people that slept more than that amount were equally harmed as those who slept too little,” says Conor Wild, Owen Lab Research Associate and the study’s lead author.

1.Where did the study take place?

A. In a lab. B. In the street.

C. On TV. D. On the Internet.

2.What may affect the result of the study according to Owen?

A. Career. B. Diet.

C. Education. D. Exercise.

3.What’s Wild’s view?

A. Sleeping too much is as bad as sleeping too little.

B. People must sleep for eight hours every night.

C. Sleeping too little can make people look older.

D. People needn’t pay attention to the amount of sleep.

4.What can we learn from the text?

A. Owen and Wild are the first to study sleep.

B. Lack of enough sleep is a common problem.

C. All the people in the world show interest in the study.

D. There is no effective way to solve the sleep problem.

A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived（感知到的）social isolation than those who said they spent a half-hour per day or less on the same sites.

According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader’s Digest. “Although people think being on social media all the time makes them ‘connected’ to others, they are actually ‘disconnected,’ because the more time one spends behind a screen, the less time one spend face-to-face.”

“Part of the issue of loneliness is that the majority of people who use social media aren’t just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else’s posts, where they are and what they are doing. The constant exposure to everyone else’s ‘perfect’ life experiences causes feelings of being left out.”

So what’s the answer? It’s simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else’s life. Just focus on your own life, where you’re going, what you are grateful for, and what you want to accomplish in this world.”

1.What is the finding of the new study?

A. Humans are social-emotional beings.

B. Social media platforms are overused by the young.

C. Social media strengthens interpersonal relationship.

D. Heavy use of Social media can lead to loneliness.

2.How did the team conduct their research?

A. By asking questions.　　 B. By experimenting.

C. By distributing forms.　　 D. By media reporting.

3.Who might have a strong feeling of social isolation?

A. Those who use a single social media platforms.

B. Those who spend three hours a day on social media.

C. Those who don’t spend time on social media.

D. Those spending a half-hour per day on social media.

4.What does Kersting suggest people do to avoid feelings of social isolation?

A. Never compare with others.　　 B. Make more fiends on the internet.

C. Choose a travel destination.　　 D. Set up a clear goal for the future.

The latest study by the University of Florida has found that eating from smaller, less beautiful, and even paper plates will help prevent overeating. Eating with a fork instead of a spoon can help you lose weight, the researchers say. Much to their surprise, they find that putting mirrors in the dining room will also help reduce weight.

The researchers asked 185 college students to choose a chocolate cake or a fruit salad, and evaluated the taste. Those who ate in a room with a mirror scored the taste of junk food much lower than those in a room without a mirror. But the taste of fruit salad remained the same in any case.

Lead scientist, Dr. Ata Jami, says that a glance in the mirror tells people more than just about their physical appearance. It enables them to view themselves objectively and helps them to judge themselves and their behavior in the same way that they judge other people.

The mirrors were found to push people to compare and match their own behavior with accepted social standards. The researchers believe it proves that people don’t want to look in the mirror when they feel they are following the social standards. When they look in the mirror with mouths full of junk food, feelings of discomfort and failure can be increased. Therefore, the presence of the mirror lowers the taste of unhealthy food.

However, researchers say this is only the case if people select the food they are eating, because they are responsible for that choice. The researchers suggest that mirrors be placed in dining rooms and other eating spaces, so that people will start eating more healthily.

1.Researchers are amazed to find that ______.

A. paper plates make food look nicer

B. people using a fork will eat more

C. mirrors can help people lose weight

D. people will eat more in front of a mirror

2.What can be inferred from the study?

A. Some teenagers got involved in it.

B. People were required to eat with a spoon.

C. People preferred a chocolate cake to a fruit salad.

D. The mirror may not affect the taste of healthy food.

3.According to Dr. Ata Jami, the mirror ______.

A. makes people judge others correctly

B. makes people well judge themselves

C. is a necessary part of people’s daily life

D. can only show the appearance of a person

4.How does the mirror affect the taste of junk food?

A. By making people hungry.

B. By showing the social standards.

C. By attracting people to healthy food.

D. By causing a feeling of discomfort.

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.

The findings came from a survey of more than 340,000 adults in the United States. The Gallup(民意调查) Organization questioned them by telephone in 2008. At that time, the people were between the ages of eighteen and eighty-five.

The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.

Arthur Stone at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.

Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.

The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
