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 Virginia 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 establish 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.
In an interview, Turek said some studies have shown sleep causes declines in an appetite suppressing protein hormone, and increases in another hormone that causes a longing for food. In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(重叠), he said.
Patness 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.
66. What’s the passage mainly about?
A. People who sleep less tend to get fat.
B. Fat people need lots of sleep to lose weight.
C. Sleeping has nothing to do with fatness.
D. Fatness has been rising dramatically in developed countries.
67. According to the passage, which of the following is TRUE?
A. Lack of sleep causes declines in a desire limiting protein hormone.
B. Americans experience sufficient sleep and fat bodies.
C. The findings suggest that major extensions of sleep time may be necessary.
D. Fatness has been rising dramatically in America.
68. Which of the following is NOT close to the underlined word suppress?
A. limit B. restrict C. accept D. control
69. According to the passage, which of the following people is the lowest possible one to get fatness?
A. Americans B. Chinese C. Japanese D. English
70. We can conclude the attitude of the author is________according to the passage.
A. worried B. uninterested C. critical D. optimistic

Exercise may hold the key to youth, according to a study published on Monday which showed people who keep fit are up to nine years biologically younger than those who do not. The findings are the first to show in humans how keeping fit affects the ageing process.
The study of 2,40twins found that a sedentary(久坐的)lifestyle raises the risk of a range of problems from heart disease to cancer and appears to play a key role in the ageing process.
It all appears to boil down to(归结为)the length of structures called telomeres(染色体终 端)---which protect the DNA on the chromosomes(染色体),the researchers from King's College London wrote in the Archives of Internal Medicine.
Many studies have shown telomeres get shorter over time, suggesting the cells are ageing or dying. The study, which extracted (提取)a DNA sample from their volunteers, found people who exercised more each week had longer telomeres.
Exercise lowers the risk of a range of problems such as heart disease, diabetes and cancer, the researchers said. “It is not just walking around the block. It is really working up a sweat." said Tim Spector, a genetic epidemiologist who led the study, in a telephone interview.
The study found people who exercised energetically 3 hours each week had longer telomeres and they were 9 years biologically younger than people who did under 15 minutes.
Spector's team, who also adjusted for body weight, smoking, economic status and physical activity at work, also said moderate(适度的)exercise for 1-2 hours each week provided a four- year advantage.
Studying twins also provided a unique opportunity to judge the effects of exercise on people with the same or similar genetic make-up. the researchers said.
The reason why exercise has this effect is not clear but the researchers said they believe physical activity somehow defends against the natural process called oxidative stress (氧化应激反应).which damages and kills cells.
1.What is the risk of sedentary lifestyle?
A.It can cause diseases.
B.It can make our cells alive.
C.It can lengthen telomeres.
D.It can keep us fit.
2.What do we know from the text?
A.Exercising can shorten the telomeres.
B.The less exercise, the longer telomeres.
C.Sitting often boils more chromosomes.
D.Telomeres affect human being's ageing.
3.What can cause ageing according to the last paragraph?
A.Cells with diseases. B.Oxidative stress.
C.Genetic structure. D.Physical activities.
4.What is the purpose of the text?
A.To introduce some exercise.
B.To show how to do research.
C.To encourage people to exercise.
D.To advise people to lose weight.

Are people less or more happy when they get older? A study in 2018 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.
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 the highest among adults between the ages of 22 and 25. 1.
Happiness was the highest among the youngest adults and those in their early 70's. But the people least likely to report feeling negative emotions were those in their 70’s and 80’s. The survey also found that men and women have similar emotional patterns as they grow older. 2.The researchers also considered possible influences like, having young children being unemployed or being single. Bu, they found that influences like these did not affect the levels of happiness and well-being related to age.
3. One theory is that, as people get older, they become more than thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
4.In another study, people in their 80’s reported the fewest problems with the quality of their sleep. The original goal was to confirm the popular belief that aging is connected with increased sleep problems. 5.But except for that, people reported that they felt their sleep quality improved as they got older.
A. So why will happiness increase with age?
B. Researchers surveyed more than 150, 000 American adults.
C. At that time, the people were between the ages of 18 and 85.
D. Stress levels dropped sharply after people reached their 50's.
E Happiness is not the only thing that apparently improves with age.
F. The survey did find an increase during middle age, especially in women.
G. However, women at all ages reported more sadness, stress and worry than men.

In a study recently published in the journal Neuron, researchers found that super memorizers don’t have unusually large brain regions that allow them to remember a lot of information. 1. Here are a few of their favorite tricks that can help you to remember things in your everyday life.
To Remember: New words
Technique: Change routine
In a study, a group of students studied a list of words in two separate sessions. Some studied in a messy room ant some in a neat space. One group of students spent both sessions in the same room, while the other split the sessions between the two environments. During a test, the students who studied in multiple places remembered much more. 2. That includes the time of day, the music in the background, whether you sit or stand, etc.
To Remember: Your PIN
Technique: Count it out
You could use your birthday, or your phone number, but identity thieves have a way of figuring those numbers out. 3. Write a four- wort sentence. Then count the number of letters in each word. For instance, “This is my PIN” =4223.
To Remember: Faces
Technique: Focus on noses
White some super memorizes specialize in associating names with faces, the memory-palace technique doesn’t work as well if the image of the face is changed in any way. Rather than focusing on eyes, as most people do, focus on the centre or to the left of a person’s nose. 4.
To Remember: Facts & figures
Technique: 5.
To learn and remember statistics, reviewing the material repeatedly over a longer time is far more effective than repeating it in a shorter one. If your exam is in a week, study today and then again in a day or two. If it’s a month away, study today and then wait a week before your second session.
A. value exams
B. Give yourself time
C. This allows you to take in their whole face.
D. Their brain structures are in fact the same as the rest of ours.
E. Instead, try this tip from Dominic, an eight-time World Memory Champion.
F. The theory is that your brain links the words to the environment around you.
G. Studies showed that varying other aspects of your environment can also help.

A new study has found that social media could be affecting the sleep of young adults.
The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.
“This is one of the first pieces of evidence that social media use really can influence your sleep.” said Jessica C Levenson. She was the lead author of a report on the study.
The researchers set out to examine the connection between social media use and sleep among young adults. Levenson noted that these young adults are possibly the first “generation to grow up with social media.”
The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media 30 times per week.”
Thirty percent of the study's participants reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.
Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be the most effective.
1.What's the main idea of the text?
A. The researchers focus on social media.
B. The researchers manage to handle sleep problems.
C. Doctors treat young patients.
D. Social media affects sleep.
2.When treating sleep problems, doctors are advised to ________.
A. offer some advice about giving up social media
B. ask the patients about young adults’ use of social media
C. give young adults some medicine
D. ask about the patients' living conditions
3.How did the researchers mainly carry out the study?
A. By doing online research. B. By giving an example.
C. By collecting published data. D. By doing questionnaires.
4.What can be inferred from the text?
A. Men are more likely to suffer from a sleep disorder than women.
B. People often using social media are less likely to have a sleep disorder.
C. Using computers less helps avoid sleep problems completely.
D. Sleep problems can be determined by the times of a person visiting social media.

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.
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 twenty-two and twenty-five.

Scientists found that sleeping considerably improves our creativity. After taking a nap people are able to think faster and put more imagination into their thinking. Besides, if we dream, the thinking abilities are improved even more.
Researchers consider that sleeping on a problem in most cases leads to elucidation(解释). They say when a person enters a phase called Rapid Eye Movement (REM) during sleep, it increases the effect. Such phase takes place right before we awake and according to scientists it helps our brain make links between unrelated subjects.
In the study, led by Professor Sara Mednick, scientists made a conclusion that the REM was “important for assimilating(消化) new information into past experience” in order to find solutions to creative problems.
Prof. Mednick is a psychiatrist at the University of California. Her study involved the analysis of 77 adults. Each participant was given several word-associated creative tasks. All tasks were given in the morning, with participants being shown a number of groups of 3 words, for example: cookie, heart and sixteen. They were asked to come up with a word that would be associated with all three given terms—like sweet. Sometime later, after some participants were allowed to sleep, they were asked to perform the same tasks and some new ones. It is worth mentioning that while some people slept, researchers used brain scans to see the type of sleep each participant entered.
When given the same tasks, participants, who took a nap, were able to give more varied solutions, some of which were much better than they gave earlier. But when given new tasks, researchers found that those who entered REM sleep had a 40 percent better result compared to the performance they showed in the morning.
1.What does “it” refer to in the second paragraph?
A. The effect. B. REM. C. Sleep. D. A problem.
2.Why do the researchers study the REM?
A. Because REM takes place just after you sleep.
B. Because REM can store more information.
C. Because REM can help find creative solutions
D. Because REM can make a creative invention.
3.What can we know from this passage?
A. Taking a short nap is good for your thinking during the day.
B. Sleeping has three processes which is good for creativity.
C. Each adult was allowed to sleep after the task was given.
D. REM is a process taking place right after we awake when we nap.
4.The important stage in the study is________.
A. to think of a creative word
B. to show a group of 3 words
C. to give participants time to think
D. to let some participants sleep for a while
