Good news for middle and high school students． When it comes to sleeping a little longer, physicians are on your side．

On Monday, the American Academy Pediatrics（儿科） announced its recommendation that middle and high schools start at 8:30 a．m．or later． "Doing so will match school schedules to the biological sleep patterns of adolescents," the AAP writes in a press release regarding its new policy statement called “School Start Times for Adolescents" ．

"Chronic（慢性的） sleep loss in adolescents is one of the most common public health issues in the U．S．today," according to Judith Owens, director of Sleep Medicine at Children's National Health System．

"The research is clear that adolescents who get enough sleep have a reduced risk of being overweight or suffering depression, are less likely to be involved in automobile accidents, and have better grades, higher standardized test scores and an overall better quality of life," Owens said in the press release． "Studies have shown that delaying early school start times is one key factor that can help adolescents get the sleep they need to grow and learn．"

Even before the AAP's announcement, school districts across the country have been rethinking start times． Earlier this year The New York Times wrote about Dos Santos, a student at Rock Bridge High School． When Dos Santos learned that school officials were considering starting school 30 minutes earlier than the existing time, she became worried．The student gathered others to her cause． In the end, school officials decided against the earlier start time．

One of the organizations that Dos Santos reached out to for help was Start School Later, a nonprofit organization that focuses on getting public schools to set "healthy school hours．"

"It's going to take collective action, perhaps on a national scale, to get many districts to take on this issue," Terra Ziporyn Snider, PhD, director and co-founder of Start School Later, told Yahoo Health．

"The science is clear, the will to change isn't," she explained． "The reason for that is that community life goes around school schedules, and any suggestion of change - earlier, later, whatever - brings powerful opposition from everyone who fears a change in routine．"

1.What can be learned about Start School Later?

A． Dr．Snider is director of this nonprofit organization．

B． It is a commercial organization belonging to Yahoo Health．

C． It helps private schools to set healthy schedules for students．

D． It made a policy called。‘School Start Times for Adolescents"．

2.Which of the following is NOT mentioned as benefit from enough sleep?

A． Students will enjoy a better life．

B． Students might feel less depressed．

C． Students may achieve higher grades．

D． Students are more likely to be on time for school．

3.What can be inferred from the last paragraph?

A． Scientific findings are not convincing．

B． Changing school　 start time is no　 easy job．

C． Most people are willing to change schedules．

D． The revolution of school schedules is under way．

Physical Benefits

1. This is especially recommended for the elders and those who have some form of disability in their voice. However, it is important to find a capable instructor to employ good singing techniques so as not to further damage vocal cords (声带) or lungs.

Getting active in midlife could be as good for you as starting young when it comes to reducing the risk of an early death, researchers have suggested. But experts say the study also shows that the benefits fade once exercise declines.

“If you maintain an active lifestyle or participate in some sort of exercise from youth to middle age, you can reduce your risk for dying,” said Dr. Pedro Saint-Maurice, the lead author of the research. “If you are not active and you get to your 40s - 50s and you decide to become active, you can still enjoy a lot of those benefits.”

The study was based on data from more than 300,000 Americans aged 50 - 71 who undertook a questionnaire(问卷) in the late-1990s. They were asked to recall the extent of their moderate to vigorous leisure exercise at different stages of their life. Researchers then used national records to track who died in the years up to the end of 2016. After taking into account factors including age, sex, smoking and diet, the team found that those who were exercising into middle age had a lower risk of death than those who had never carried out any leisure exercise. However, when the team looked at different patterns in the way people were active over their life, it found a surprise.

Men and women who started exercising at the age of 40 - 50 reduced their risk of death from any cause by about 35%. The benefit was similar to that seen for people who reached and maintained similar activity from their teens or 20s onwards.

However, the study found that the protective effect of exercise did not last forever. People whose levels of leisure exercise decreased by middle age had no difference in the risk of an early death to those who had always been couch potatoes. “If you have been active and you slowly decrease your exercise participation as you age, you lose a lot of the benefits that we know are associated with exercise,” Saint - Maurice said.

But the study has limitations, including that it is based on individuals recalling how active they were many years before. What’s more, the research looked only at death records, not other aspects of health such as levels of sickness and disease. Nonetheless, he said, the message was positive. “This adds to the growing body of evidence about the importance of physical activity and exercise across he life course, and indicates that it is never too late to start.”

1.Which of the following is TRUE about the study?

A.The study took about two decades to complete.

B.The study involved around 30,000 elderly Americans.

C.Questionnaires and interviews were the sources of data.

D.The participants in the study took regular physical exercise.

2.According to the passage, what does “a surprise” (Para.3) refer to?

A.The earlier you exercise, the greater your health benefits will be.

B.Participating in exercise from youth to middle age benefits one’s health greatly.

C.The benefit of getting active in midlife is similar to that of starting young.

D.The benefits of exercising in midlife will decline once you stop exercising.

3.It can be inferred from the passage that _________.

A.an active lifestyle will not necessarily bring positive health benefits.

B.participants’ memories may affect the reliability of the study result

C.people exercising from their teens can maintain health forever

D.women benefit more from vigorous exercise than men do

4.Which of the following might be the best title of the passage?

A.Exercise has its limitations, studies show

B.Getting active when young, experts suggest

C.Health benefits fade with age, doctors warn

D.Never too old to start, researchers say

Many of us suffer needlessly when it comes to our well-being or physical health. In most cases this can be attributed to a lack of knowledge about our lifestyle to include our eating habits along with physical activity. If we learn how to keep healthy, our lives would be so much more enjoyable.

With so many places to find a fast meal, it is hard to maintain control of your eating habits when coupled with a fast pace lifestyle. We do need food to provide the energy our bodies need, but it is our choices that ultimately help or harm us. From increasingly large burgers to fried chicken, we are attacked with endless quick meals. However, we must give our body what it needs to get healthy and not what our taste buds want.

The other key component to keeping healthy is regular exercise. You don’t have to be a gym rat or anything of that nature, but you must develop some type of workout. It can be something as little as walking. Exercising just 30 minutes of your day is all you really need if you want to stay healthy. You can do as little as 3 to 4 days a week or make it a daily routine.

Our bodies are not equipped to deal with stress on a routine basis. Constant stress can lead to a rise in blood pressure which increases your chance for a stroke or a heart attack. It also affects the blood cells that aid in fighting infections. These weaken cells leave you helpless against common colds, other illnesses, and medical conditions. Therefore, you should learn to relax yourself by spending some time every day chatting with your family, playing with your friends or just watching a film or listening to some soft music.

There is no big secret on how to keep healthy. If you take care of your body, it will do the same for you in return. It is best that you take every measure possible to lead a healthy lifestyle. Keep healthy by treating your body right.
